The wormhole theory postulates that a theoretical passage through space-time could create shortcuts for long journeys across the universe. Wormholes are predicted by the theory of general relativity. But be wary: wormholes bring with them the dangers of sudden collapse, high radiation and dangerous contact with exotic matter. We asked physicist Robert Kehoe, some frequently asked questions about wormholes. Robert Kehoe Professor, Department of Physics, Southern Methodist University Robert Kehoe is a physicist currently studying the nature of the accelerating expansion of the universe. He is a lead researcher on the Dark Energy Spectroscopic Instrument (DESO), which is creating a far-reaching map of our universe. His research has also included work in particle physics, including contributing to the discovery of the Higgs boson, a previously only theoretical subatomic particle that allows for things to have mass. Are wormholes theoretically possible? A wormhole is thought to be essentially a tunnel from one place in space to another. When you have a massive object in spacetime, it basically creates a curvature of the spacetime in the nearby region. As you get more and more mass, we expect that that curvature becomes more and more extreme. We think such objects occur in the universe, and they are what we call a black hole, where light cannot escape due to this extreme curvature of spacetime. We think what happens is, at some point, if the mass of an object becomes large enough, the other forces of nature besides gravity can't support the matter, and it becomes a black hole. You could think about this as one side of a wormhole. Could you have a situation in which the curvature is extreme enough to connect up with something analogous on the other side somewhere else in spacetime? Theoretically, that could be true. Has a wormhole ever been found? No. We have a substantial amount of evidence for the existence of black holes. But there's been no wormholes found. Are there different types of wormholes? There are different theoretical implementations of our theory of gravitation, called general relativity, that would describe wormholes with somewhat different properties. For instance, one of the big distinctions in the types of wormholes that are described are whether or not they are traversable — by that I mean, whether you can go from one end to another. When was the wormhole theory created? Wormholes were first theorized in 1916, though that wasn't what they were called at the time. While reviewing another physicist's solution to the equations in Albert Einstein's theory of general relativity, Austrian physicist Ludwig Flamm realized another solution was possible. He described a "white hole," a theoretical time reversal of a black hole. Entrances to both black and white holes could be connected by a space-time conduit. In 1935, Einstein and physicist Nathan Rosen used the theory of general relativity to elaborate on the idea, proposing the existence of "bridges" through space-time. These bridges connect two different points in space-time, theoretically creating a shortcut that could reduce travel time and distance. The shortcuts came to be called Einstein-Rosen bridges, or wormholes. "The whole thing is very hypothetical at this point," said Stephen Hsu, a professor of theoretical physics at the University of Oregon, told our sister site, LiveScience. "No one thinks we're going to find a wormhole anytime soon." Wormholes contain two mouths, with a throat connecting the two, according to an article published in the Journal of High Energy Physics (2020). The mouths would most likely be spheroidal. The throat might be a straight stretch, but it could also wind around, taking a longer path than a more conventional route might require. Einstein's theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way its gravity affects light that passes by. Certain solutions of general relativity allow for the existence of wormholes where the mouth of each is a black hole. However, a naturally occurring black hole, formed by the collapse of a dying star, does not by itself create a wormhole.

Dr. Martin Savage is a professor of nuclear theory and quantum informatics at the University of Washington. His research explores using quantum computing to investigate high energy physics and quantum chromodynamics.Dr. Savage transitioned from experimental nuclear physics to theoretical particle physics in his early career. Around 2017-2018, limitations in classical computing for certain nuclear physics problems led him to explore quantum computing.In December 2022, Dr. Savage's team used 112 qubits on IBM's Heron quantum processor to simulate hadron dynamics in the Schwinger Model. This groundbreaking calculation required 14,000 CNOT gates at a depth of 370. Error mitigation techniques, translational invariance in the system, and running the simulation over the December holidays when the quantum hardware was available enabled this large-scale calculation.While replacing particle accelerator experiments is not the goal, quantum computers could eventually complement experiments by simulating environments not possible in a lab, like the interior of a neutron star. Quantum information science is increasingly important in the pedagogy of particle physics. Advances in quantum computing hardware and error mitigation are steadily enabling more complex simulations.The incubator for quantum simulation at University of Washington brings together researchers across disciplines to collaborate on using quantum computers to advance nuclear and particle physics.Links:Dr. Savage's home pageThe InQubator for Quantum SimulationQuantum Simulations of Hadron Dynamics in the Schwinger Model using 112 QubitsIBM's blog post which contains some details regarding the Heron process and the 100x100 challenge.

26| Networks, Heartbeats & the Pace of Cities — Geoffrey West

Why do whales live longer than hummingbirds? What makes megacities more energy efficient than towns? Is the rate of technological innovation sustainable? Though apparently disparate the answer to these questions can be found in the work of theoretical physicist Geoffrey West. Geoffrey is Shannan Distinguished Professor at the Santa Fe Institute where he was formerly the president. By looking at the network structure of organisms, cities, and companies Geoffrey was able to explain mathematically the peculiar ways in which many features scale. For example, the California Sea Lion weighs twice as much as an Emperor Penguin, but it only consumes 75% more energy. This sub-linear scaling is incredibly regular, following the same pattern across many species and an epic range of sizes. This is an example of a scaling law. The heart of the explanation is this: optimal space-filling networks are fractal-like in nature and scale as if they acquire an extra dimension. A 3D fractal network scales as if it is 4D.

A particle accelerator is something that scientists use to study the behavior of particles and conduct physics experiments. These machines use an electromagnetic field to make tiny particles move at practically the speed of light: a whopping 186,000 miles per second! So, yeah, a guy stuck his head in one of those… and actually survived! The incident happened in Russia on July 13, 1978. Anatoli Bugorski was a researcher at the Institute for High Energy Physics and worked with the U-70 Synchrotron, the biggest Soviet atom smasher of the time. On that unfortunate day, the scientist was trying to figure out why a piece of the equipment wasn't working as it should. As he was leaning over the machine, the safety mechanism failed at the worst possible moment. It turned out that the scientist's head was right in the path of a powerful proton beam moving at the speed of light. You ready to hear all about it? Then watch the video!

Edoardo Boncinelli, Antonio Ereditato"Tutto si trasforma"Breve storia dell'energia dal Big Bang al nucleare, dalle particelle elementari alla vita.Il Saggiatorehttps://www.ilsaggiatore.com/C'è una domanda aperta che anima la natura dell'universo e condiziona le nostre esistenze quotidiane: che cos'è l'energia? Un dilemma scientifico e filosofico al tempo stesso, che ha suscitato altre questioni irrisolte: da dove proviene l'energia? Perché il nostro pianeta, le nostre città e i nostri corpi ne hanno costante bisogno? Perché sentiamo parlare continuamente, nei più diversi contesti, di crisi energetica e di energie rinnovabili?Dagli attimi immediatamente successivi al Big Bang fino alla formulazione delle teorie quantistiche, esplorando il macro e il microcosmo, Edoardo Boncinelli e Antonio Ereditato nelle pagine di Tutto si trasforma hanno deciso di rispondere a questi interrogativi, che da secoli generano incessanti dibattiti, e raccontare una storia dell'energia come motore e causa prima di ogni cosa viva: che si tratti del nostro organismo, di una centrale nucleare o di una delle infinite stelle del cosmo.Il risultato è un viaggio nei «misteri energetici» – l'entropia, la materia oscura, il funzionamento cellulare – e nelle tante scoperte del mondo della scienza – la relatività di Einstein o gli esperimenti per intrappolare il Sole in laboratorio – che ci permettono di leggere questa breve storia di 13 miliardi di anni come la storia stessa della vita.«Tutto nacque con un'immensa quantità di energia comparsa non si sa come. Proprio in quell'attimo fatidico, senza quando e senza dove, essa apparve, tutta assieme, dal nulla. Da allora ha iniziato una folle serie di trasformazioni e cambiamenti, ma senza mai diminuire né aumentare.»Antonio Ereditato (Napoli, 1955) è visiting professor di Fisica all'Università di Yale e professore emerito presso l'Università di Berna, dove per molti anni è stato direttore del Laboratory for High Energy Physics.

In 2020, the esteemed physics professors Eugene Chudnovsky and Luis Anchordoqui published the paper “Can Self-Replicating Species Flourish in the Interior of a Star?” in Letters in High Energy Physics. Their paper describes a theoretical form of life wildly unlike anything else. While all life we know of is built on storing and replication information ("genes") in the long, twisted ladder-like molecule we call DNA, Eugene and Luis suggest that a combination of two hitherto unobserved phenomena predicted by string theory, cosmic strings and monopoles, could perform the tasks of DNA by combining into "necklaces". In this mind-expanding episode, Eugene explains: – What monopoles and cosmic strings are – How these two things could combine to form something that could store information about itself, and replicate - inside a star – Why this kind of life potentially could evolve a million times faster than DNA-based life – and finally, the very esteemed professor REALLY lets his imagination flow! Eugene Chudnovsky received his undergraduate, graduate, and postdoctoral education at Kharkiv University in Ukraine, and has been engaged in human rights for years, among many other things as Co-Chair of the Committee of Concerned Scientists. We talk a bit about his experiences in the Soviet Union before he left for the US. The episode was recorded before the invasion of Ukraine. Ads: Wunderdog exists because of my patrons.

Get in touch.The Omega BaryonIntroductionThe Omega Baryon is the strangest particle we have encountered so far. It may also be the strangest particle known to Science, literally.With a mass of 1672.4 MeV, the Omega Baryon is heavy. As well it should be. It is comprised of three, strange quarks. The three strange quarks gives the Omega an electric charge of three times minus one third, or minus one. Those strange quarks also gives it the unusually long lifetime of about 8% of a nanosecond. While short by our standards - even a bit shorter than some other strange particles - a solid fraction of a nanosecond is an enormous lifetime for a particle with such an enormous mass.The Decay of Strange QuarksAs if on brand, this strangest of the strange particles lives for so long precisely because its made from only strange quarks. The strange quarks, you might recall, struggle to decay. They wouldn't decay- actually - if not for a mild identity crisis.The strange quarks talk to other particles both by photon, gluon and by W boson. That is, in addition to the electromagnetic force, strange quarks communicate via both the strong and weak nuclear forces. From the strong force's perspective, strange quarks are distinct. Just like the up and down quarks. Nobody is confused, all that that subnuclear gu respects their identity as strange quarks.The weak force hedges a bit. The W-boson in particular is a little confused on who is who, and from its perspective down and strange quarks are a little mixed. Just like North and West mean slightly different things to a compass or a cartographer, down and strange quarks appear slightly different to the strong and weak forces. They're almost aligned, but not quite.As a result, the strange quark decays by W boson as if it were a down quark. That decay is amplified by the strange quark's heavy mass, but its still a small effect. The weak nuclear force is… well… weak.Being made of three strange quarks, the Omega baryon decays once one of its constituents does.Omega Baryon Decay ChannelsThe Omega minus decays when one of its strange quarks throws out a W boson, changing its identity to an up quark. Typically the W-boson then decays to a pair of quarks itself, an antiup and a down quark. This all happens quickly inside the baryon itself, which subsequently explodes into a pair or triplet of particles. There there are a number of possible results.Two-thirds of the time, that anti-up quark SCORES and runs away with one of the Omega's other strange quarks, creating one of those tricky K minus mesons that we've discussed previously. What's left over? An up, a down and a strange quark, which manifests as a Lambda zero baryon.Twenty-three percent of the time, that anti-up quark isn't so lucky. It remains stuck so the down quark that came from W boson, which together run away as a negatively charged pion. The quarks that remain - two strange and an up - comprise the neutral cascade or Xi baryon, which of course leads to its own cascade of particle decays.Almost all the rest of the time - that's about 8% for you bean counters out there - the Omega baryon spits out a neutral pion, decaying to a Xi minus instead. For this to happen, that down quark has to hold on tight to that pair of strange quarks that didn't decay.On extremely rare occasions, instead of a neutral pion, the Omega decays to Xi minus by spitting out a pi+ pi- pair. This could happen, for instance, the resulting up and antiup quarks happened to find a down-anti down pair inside the subnuclear goo.Spin and the DecupletIn addition to having three strange quarks, the Omega baryon also has three times the angular momentum of most baryons we've encountered so far. Inside the baryon, those three strange quarks are all zooming around each other, extra fast.We've seen this behavior before, when we looked into the Delta baryons. The Delta Plus Plus baryon, you might remember had three up quarks. And the Delta Minus baryons, which had three down quarks.In a sense, the Omega baryon is the strange version of those beasts. Because of that simple, three strange quark arrangement, the Omega baryon was predicted to exist well before it was found. Well, that's… not exactly right. In fact, it's exactly backwards. Back in the 50s and early 60s nobody knew what a quark was, or how baryons were even organized. They just had all those wild names: Delta. Sigma. Xi. This zoo of strange particles was something of a mystery. The physicist Gell-Mann (and, independently Ne'eman) chased the patterns of all the particles and their decays and divsed the quark model to fit those data. There was only one problem: one particle was missing. The Omega baryon was discovered as a short stub of a line which appeared on a photographic plate at Brookhaven national Lab. It had essentially the same mass, spin and charge that Gell-Mann predicted, ushering in the first of many experimental verifications of the quark model of subnuclear physics.And that concludes our second - STRANGE - season of the Field Guide to Particle Physics!

Get in touch.The Cascade ParticlesPrepare for trouble! And make it double! Today we confront the two Cascade or Xi /ksee/ baryons which each have a PAIR of strange quarks.Xi minus checks in with a mass of about 1322 MeV, making it the heaviest baryon we've encountered so far. This is just as well, as it comprised of two of those heavier, strange quarks. Together with a third, down quark, it also has a total electric charge of minus 3 thirds or… minus one.Xi 0 is just a little bit lighter with a mass of 13 hundred and 14 MeV. Its two strange quarks are paired with an up quark, which gives it an electric charge of twice minus one third PLUS one third, or… zero.Decays of the Xi minusLike many strange particles, the cascades take quite a while to decay. The Xi minus takes a solid fraction of a nano-second, the usual time it takes to convince one of those strange quarks to decay into an up quark. The result? The strange-strange-down bag of quarks converts to up-strange-down bag, otherwise known as the Lambda 0 baryon. As usual, that decay is accompanied by some other junk, and in this case the net result is a pi minus.As we've already seen, the Lambda 0 and the pi minus are both unstable themselves. The former converts to either a proton or a neutron and the latter typically decays to a muon and then an electron.If you tried to sketch that all out, you'd find a LONG decay chain of a LOT of different particles. This gives the cascades their name. Producing ONE Xi baryon results in a cascading SHOWER of particles all the way down to that familiar, stable stuff like protons, neutrons and electrons.Now the Xi minus ALMOST ALWAYS decays to the Lambda 0 with a pi minus. Like 99.8 percent of the time! The rest of the time we find some cuter decays, each incredibly rare, happening less than a thousandth of a percent of the time. These rarer decays shed some rather alarming light on the very identity of the strange quark. But BEFORE we get to that, we should talk about the Xi 0.Decays of the Xi 0The Xi 0 takes about TWICE as long as the Xi minus to decay, which is still, only a third of a nano-second. What's short for humans is a seriously overripe old age for an elementary particle.Like it's partner, the Xi 0 decays into a Lambda0 with a pion. This time a neutral pion. This happens 99.5% of the time. These decays are a little twisted.Its is the same thing we saw with those charged sigma baryons. We need to convince an a bag of of three quarks: up-strange-and-strange, to decay in something that looks like the up-down-strange bag of the Lambda zero. This is troublesome precisely because the strange quark ONLY EVER decays to an up quark.As with decays of the Sigma baryons, things just need to rearrange a little bit. The Sigma Plus you might recall decays into a proton and a pi zero thanks to a W boson. Similarly, one strange quark of the Xi0 decays to an up quark by emitting a W- boson. The W- decays to a down-anti-upquark pair so fast the rest of the quarks barely notice. The down quark runs away with the other “up and strange” quarks from the original Xi 0, and the anti-up quark leaves with the freshly minted up quark as a neutral pion.If that sounds convoluted, it is. It helps to have a diagram to look at, which you can do on our website, pasayten.org.Incidentally, the other, rarer decays of the Xi zero match up quite nicely what you'd expect from those rare decays of the Xi minus. More on those in a later episode.Spin Angular MomentumThe spin angular momentum of both Xi 0 and Xi minus is simply hbar over 2, just like the proton and the neutron. Well those and the three Sigma baryons AND the Lambda baryon. That's a total of eight distinct particles, which is a lot, but you can rest easy knowing there are NO other particles with that spin angular momentum made from combinations of those three quarks. And this is no accident. Any OTHER, three particle combination of up, down and strange quarks - like a baryon with three of the same quarks, like the Delta Baryons we've already seen - will have a higher spin angular momentum. You could think of that as if the quarks were orbiting each other inside that subnuclear goo at a faster and faster pace. And we'll meet some examples of these soon enough. The story behind WHY this should be is fascinating, nerdy and otherwise adds some useful scaffolding to an ever expanding ZOO of wild, subatomic particles.More on that, next time.

Get in touch.The Neutral Sigma BaryonsIntroductionWeighing in at 1192 MeV, the middle-weight sigma baryon is also the the electrically neutral one.The Sigma Baryons are a trio of strange, slightly heavy cousins to everyday particles like the proton and the neutron. We've already talked at length about the charged Sigma baryons. Today, we're focusing on their electrically neutral sibling, Sigma Zero.While the decay resistant charged sigma baryons - with their unusually long lifetimes - certainly qualify as “strange” particles, the sigma zero feels far less strange. At least at first.The Sigma Zero decays rapidly. Tens of trillions of times faster than its charged siblings Sigma Plus or Minus. If you're into really small numbers, or just to measure time in seconds, that's a decimal point followed by 19 zeroes before you get 7 and then a four. 0.000000000000000000074 secondsThat's too short a time for us to fathom, but its about right for an unstable particle that heavy.Remember, it is STRANGE that the typical lifetime for strange baryons like Lambda Zero or the Charged Sigmas can be measured in nanoseconds. So why does the sigma zero baryon decay so quickly? OR why do we even consider it to be in the “Strange” family?DecaysOne reason to consider sigma zero “strange” is because it decays to a strange particle. Specifically, it decays, 100 percent of the time, to a lambda zero.In the process, the sigma zero throws out a photon - that is, a gamma ray - which itself might be hard to explain. You see, photons carry the electromagnetic force. Photons are passed around like baseballs between particles that have an electric charge. Photons can be thought of as building blocks for electric and magnetic fields. SO what business does the uncharged Sigma Zero - or Lambda Zero for that matter - have interacting with a photon?Electrically neutral pions, you might recall, decayed into a PAIR of photons. So perhaps it's not weird. But pi zero decays were something of an anomaly. Literally. You might recall that pi zeros decayed to two photons because of the chiral anomaly. It involved these wild, quantum mechanical beasts known as instantons. Very nonlinear, very intricate, unusual stuff. In some sense, the neutral pion just vaporized into the electromagnetic field.This is decidedly NOT what happens with Sigma zero. It doesn't vaporize. It just decays like any other particle. So what gives?To understand HOW an electrically neutral particle could spit out a photon, we have to look inside the baryon to that subnuclear goo of quarks and gluons.InnardsThe Sigma baryons are all bona fide strange particles, they all have a strange quark. Sigma Plus had two up quarks and a strange quark. Sigma minus shad two down quarks and a strange quark. Can you guess what a Sigma Zero has?One of each. Up, down and strange.But wait. Wasn't the Lambda Zero ALSO made up from an up quark, a down quark and a strange quark? Well yes. And that fact explains in fact, why the sigma zero decays so quickly. It decays to the lambda zero because they both share the same number and kind of internal or valance quarks. As it turns out, the Sigma Zero is something of an “Excited” version of the Lambda zero. Internally, you might say that the up and down quarks are buzzing around in a slightly different configuration. A configuration with slightly more energy. They're a little more spun up, as it were. That bit of spin energy gets released by the emission of a photon, leaving that bag of quarks and gluons with lower internal energy, otherwise known as the particle Lambda Zero.E = mc^2 after all just means that the MASS is proportional to ENERGY.Including PhotonsThe internal structure of the Sigma Zero also explains why an electrically neutral particle can throw out a photon. It's just electrically neutral on AVERAGE. The average value of the electric charges of all the quarks is zero. But individually, they each have a charge.This brings us back to the story of the neutron. While the AVERAGE electric charge of a neutral baryon is zero, the electromagnetic field need not be identically zero.Like the neutron or the earth, the Sigma Zero baryon has a nonzero magnetic dipole moment. It probably should also has an electric dipole moment. All this means is that the electromagnetic fields kind of averages out to zero, but are still smeared out, in a way.And it's these smeared out configurations that allow the Sigma Zero to throw out a photon and decay to a lambda zero. Or at least, that's another fun way to think about it.

Get in touch.The Charged Sigma BaryonsIntroductionThe Sigma Baryons - that's a capital Sigma - are a trio of slightly heavy cousins to everyday particles like the proton and the neutron. With masses of almost 1200 MeV each, it may surprise you that the physics of Sigma baryons feels much closer to a comparatively puny trio of familiar particles: the pions.The pions form a triplet of mesons: pi plus, pi zero and pi minus. So too, do the Sigmas: Sigma Plus, Sigma Zero and Sigma Minus. The similarities are helpful for building an intuition, but the differences are stark. While the charged pions are antiparticle partners, the charged Sigmas are anything but.Today we'll focus on that fact as we explore the pair of particles Sigma Plus and Sigma Minus. Charged SigmasThe charged Sigma baryons are your typical strange particle. They live much longer than they should, given their mass. Their lifetime is a sizable fraction of a nanosecond. Like the Lambda Zero, the charged Sigma baryons live so long because they have to wait for their constituent strange quark to decay.The strange quark can only decay to an up quark, and while possible, it takes a while. It's a quantum bottleneck that in particle decays that has come to be known as the technical term “Strangeness”. While the down quark and the strange quark have separate identities as far as the strong nuclear force is concerned, they mix slightly under the weak nuclear force. That slight mixing is what gives the strange quark a chance to decay.And it always decays to an up quark. Keep an eye on this fact. It's what makes the Sigma baryon decays so tricky.What's fun about the charged Sigma Baryons - that is markedly DIFFERENT than the charged pions - is that they are NOT antiparticles for one another. ¿The ANTI sigma plus is NOT the sigma minus. Not even close.The Sigma Plus has two up quarks and a strange quark. That gives it's electric charge of two thirds plus two thirds minus one third or one. The Sigma Minus has two down quarks and a strange quark, which contribute a charge minus one third each. So, despite having opposite electric charges, they have very different quarks inside:up up and strange versus down down and strange. And with that constitutional difference comes more mundane ones: the Sigma Plus and Sigma Minus have slightly different masses AND slightly different lifetimes. They are, in other words, very different particles.Still. The Sigmas try their best to behave like pions. Isn't it nice how neatly organized Nature at least tries to be?At 1197 MeV, the Sigma minus is just a little bigger than the Sigma plus, whose mass is about 1189 MeV. Bigger masses usually imply short lifetimes, but the Sigma Baryons are strange in this sense too. The heavier, sigma minus baryon has a lifetime around 15% of a nanosecond. The lighter sigma plus baryon decays about twice as fast, living on average for about 8% of a nanosecond. Charged Sigma Baryon DecaysWhy does this slightly lighter, sigma plus baryon decay twice as fast?Sigma Plus has two major ways to decay whereas Sigma Minus has only one. Sigma Minus only really decays to a neutron and a pi minus. There are other options - including muons, electrons, neutrini and, rarely, a lambda zero-electron pair - which all together occur less than 1% of the time.Similarly, 99% of the time Sigma Plus will decay into a familiar nucleon and a pion. But here's a slight imbalance between these two options. The proton and pi zero appears just over 51% of the time. The neutron and pi plus happens a bit of 48% of the time.Amusingly, the other 1% of stuff looks exactly like the anti particle versions of the rare Sigma minus decays. You know, antimuons, positrons and neutrinos. Notably, there's also a rare Lambda zero with positron decay. Charge has to be conserved, after all.Because the sigma plus has two ways to decay - two decay channels, in the parlance of particle physics - it's not surprising that it decays twice as fast as its negatively charged sibling.Why the sigma minus only has one decay channel relates back to the fact that is NOT the anti particle partner of sigma plus. Despite its negative charge, it's made of QUARKS and not ANTIquarks. Because there is no negatively charged analog for the proton, there's nothing else for the sigma minus to decay into.Some Gory, Decay DetailsThe details of these decays are fun to examine.The sigma minus - down, down, strange - decays when the strange quark does. The strange quark emits a W boson and leaves behind an up quark. That essentially converts the Sigma minus into a neutron - down, down, up. The W boson promptly decays into a down quark-antiUp quark pair - that is, a negatively charged pion.Did you get that? Sigma minus decays to a neutron with a pi minus.The sigma plus - up, up, strange - is a bit more complicated. The strange quark again decays, but the final combination of quarks: up, up, up, down, anti-up, can be rearranged to form a proton: up, up, down and a neutral pion: up / anti-up. Because the W-boson lives for such a short time, that rearrangement all essentially happens at once.The other possibility for the sigma plus is even more wild. The strange quark decay as usual, laving behind an up quark, but the emitted W-boson is immediately absorbed by one of the other up quarks, which then converts it into a down quark. If a gluon just happen to be emitted at around the same time, it can convert to a down quark-anti-down quark pair, giving a final combination of quarks: up, down, down, anti-down, up. This can be rearranged to form a neutron (up-down-down) and a pi plus (up-anti-down).Was that complicated enough for you? Converting a sigma plus to a neutron is a little more complex so it doesn't happen quite as often. To get a better sense of visualization, check out our drawing on the website. But suffice it to say, gluons aren't hard to find given all that nuclear goo those quarks live with. It's not all that surprising things work out this way.We should say that these descriptions are something of a sketch or skeleton of what is actually going on. Physicists doing the full calculation using Quantum Field Theory would call it a tree-level approximation. Quantum effects can sometimes be dramatic, as we saw with the pi zero. Mercifully, not in this case.Particle physics is nothing if not messy.Why no Lambda Zero?If you're numerically minded - like you accountants out there - you might wonder why these charged Sigma baryons do not decay into a Lambda zero baryon. After all, the mass of the charged sigmas is around 1190 MeV, but the mass of the Lambda zero is only just shy of 1116 MeV. Energetically, it's more than possible! But the details matter.Both Sigma plus and sigma minus can and do decay to Lambda 0 with either a positron or an electron, respectively. But it's a needle in a haystack. For every MILLION charged sigma baryons you produce - say from cosmic rays in the upper atmosphere or at a particle collider - you can probably count the number of Lambda Zero's produced on one hand. Why is it so rare? Well the strange quark - slow as it is to decay - decays to an up quark much, much faster than the down quark does. Like a few parts per million times faster.So the statistics all wash out, in the end.ConclusionWhile the charge sigmas have trouble decaying into a Lambda zero, the sigma zero baryon does not. This leads to another fun story, which we'll visit next time.

Get in touch.The Neutral KaonsBefore we can describe neutral kaons in the wild, we need to take a quick detour to the city.South of Downtown Seattle resides the historic Pioneer Square. Bricks line the sidewalks and the ends of metal, reinforcement bars stick out of the old, stone buildings. Approaching the iconic Smith Tower, you cross Yesler Way, and something happens. The direction of the streets change.South of Yesler, the streets all run north-south. The grid, in other words, matches the cardinal points of the compass: north south, east west. When you cross Yesler, confusingly, everything rotates by 45 degrees.The streets of downtown Seattle - between Yesler Way and Denny Way - all point Northwest. The rotation of streets is made to match the contour of Elliot Bay. The waterfront goes NW to SE. Streets run parallel and perpendicular to it.It's often easier for us to think in terms of north south east west, but sometimes the geographic features of the terrain forces a change. There are still two directions, it's just a shift in our frame of reference.This idea of a 45-degree shift in our frame of reference, mixing North with West and South with East, is very similar to how the neutral kaons behave.Introducing the Neutral KaonsThere are two, electrically neutral kaons. K0 and K0bar. Like the eta and eta prime mesons - which are also electrically neutral - these neutral kaons are mesons that include a strange quark.The strange quark is like the down quark, only quite a bit heavier. Because it's heavier, the particles comprised of them like the kaons, also tend to be heavier.Mesons - like the kaons - are quark molecules made from one quark and one antiquark. The strange quark is a heavy version of the down quark, and so both have an electric charge of -1/3. Neutral kaons are combinations of to quark-antiquark pairs: down-antiStrange and strange-antiDown. These two combinations are called K0 and K0bar, respectively.With masses just shy of 500 MeV, these neutral kaons are heavy. Unlike the heavy and short-lived eta and eta prime mesons, the lifetime of these neutral kaons is considerably longer. Like the Lambda zero baryon, the strange quark makes it difficult for the neutral kaons to decay. How they decay brings us back to the streets of Seattle.The Long and Short of itThe charged kaons presented a mystery because they could decay to both three pions and two pions. This confused particle physicists for quite some time. Neutral kaons also share this curious property, with nuance, of course.Like the street map of Seattle, K0 and K0bar mix. While moving through space, a K0 can spontaneously change into a K0bar and vice versa. This mixing is something of an artifact of an even stranger phenomena. Strictly speaking, neither the K0 nor K0bar mesons interact with Weak nuclear force. Only mixtures of them interact the W bosons. Just like North and East can combine to Northwest and Northeast, we think of these kaon combinations as K0 plus K0bar or K0 minus K0bar. It's like a rotation by plus or minus 45 degrees.How is the possible? In a word, Quantum Mechanics. You might say that the Strong nuclear force - the thing that binds quarks together into bigger particles - respects the individual identities of those quarks: up, down and strange. The Weak nuclear force, however, does not. These particle-antiparticle oscillations are similar to the flavor oscillations experienced by the three flavors of neutrini. The “minus” combination is sometimes called K-short, because it decays relatively quickly: just shy of 8 percent of a nanosecond. The “plus” combination is sometimes called K-long, which takes 50 nanoseconds,.Any nanoseconds is an eternity by particle physics standards, but it's remarkable that K-short decays 1700 times faster than K-long given that they're made of the same things.In some sense the K0-K0bar mixing occurs because the “K-short” combination wants to decay so much faster than “K-long”. Given a beam full of ONLY K0 particles, it will eventually turn into ONLY a beam of K-long particles. The K-shorts will all decay.K-short decays into pairs of pions, either two pi0s or a pi plus-pi minus combination.K-long decays into three pions: either one of each or three pi zeros. K-longs actually decays into electrons or muons too - or their associated antiparticles - along with a single charged pion of opposite charge.In SummaryThe number of fine details in the mixing of neutral kaons is staggering. I'll give you three examples. First: if a K0 decays into an electron-like particle, it's virtually always going to be the anti-electron with a pi minus. Second, and oppositely, if K0bar decays like that, it will always output an electron with a pi plus. Finally, there is an extremely small mass difference between K-long and K-short. 3 parts per trillion. The quantum mixing of the two neutral kaons is just the first hint that particle physics only gets more complex and strange as we delve deeper into it. So take a breath. Relax your shoulders. And then get excited. There's still plenty more to see.

Get in touch.The Eta and Eta Prime MesonsThe Eta and Eta Prime particles are a pair of electrically neutral particles that were - for a moment anyway - the center of a fierce debate among physicists. That debate ended as quantum chromodynamics - the mathematical theory which describes how quarks and gluons interact - was enshrined into the standard model of particle physics.Those mathematical details involved in describing eta and eta prime are almost as fierce as the debate over how they worked. And those details are what we'll describe today.With the strange quark, three are three kinds of quarks that can combine into all sorts of particles: up, down and strange. Of course, they each have antiparticle partners: antiup, antidown and antistrange with opposite electric charge.Mesons are particles that mix quarks and antiquarks. The neutral pion is a pretty clean mixture of direct quarks/antiquarks pairs: up-antiup with down-anti-down.Nature can also make nice, clean, symmetric combinations of all three quarks: up-antiup, down-antidown, strange-antistrange. Actually, it can make two of them, because, you know, strangeness. Those two combinations are known as the eta and eta-prime mesons, respectively.Like the pi0, both eta and eta prime have zero electric charge, but these strange mesons are heavy. Eta itself weighs in at 547 MeV, a good four times the mass of the neutral pion. Eta prime's mass is an outrageous 957 MeV, heavier than both the proton and the neutron.The reason the eta mesons are so heavy is related to the fact that the neutral pions decay so quickly. You might remember that the neutral pions decay much faster than the charged pions. In some sense, the charged pions are protected from decaying by the conservation of charge. To be precise, pi0 mesons decay via the chiral anomaly. Quantum mechanics gives rise to sudden host of all the quarks appearing all at once which vaporizes into a pair of photons.Like the pions, the eta and eta prime mesons are electrically neutral. They have no electric charge to conserve and also decay through that quantum mess at at a much more reasonable 10^-19 and 10^-21 seconds , respectively. The lighter, eta meson typically decays just like the neutral pion, that is into a pair of photons. Sometimes it will decay into triplet of pions! Either all three pi0 or one of each, pi + pi - and pi0.The heavier, eta prime meson typically decay into the eta meson and a pair of pions: oppositely charged or neutral. Not infrequently, eta prime will decay instead to a photon plus an unstable, neutral rho meson, which is like the neutral pion, except its constituent quark antiquark pairs are orbiting each other.The same mess of quantum effects that causes all these neutral mesons to decay quickly has one more interesting effect on the eta and eta prime mesons. It explains their heavy masses.The cloud of quantum particles - all those quarks appearing all at once - collectively act to impede their physical motion through space. Physicists have a word for this phenomena. It's called a mass.Different particles experience this mess in different ways, which explains their different masses. The pions barely notice. The eta meson feels it a bit. The eta prime meson feels it the most, which is also why it is the heaviest of the bunch.The debate amongst particle physicists amounted to precisely how these masses came about, and how the Chiral Anomaly was involved. We now understand that the quantum mess of quarks which causes the pi zero and eta to decay to photons and which gives eta prime its enormous mass, are related to instantons - which are like kinks, wrinkles and textures in the quantum subnuclear goo we've been talking about. You know, that amorphous stuff that surrounds all these quarks inside particles.

Get in touch.Charge KaonsStrangeness - as a property of particles - was an attempt to explain why some particles took a really long time to decay. By that measure, the charged Kaons are definitely strange.Weighing in at 493 MeV, the charged kaons are heavy. Three times as heavy as the pions. And yet, given their mass, it's surprising that they're lifetime is also measured in nanoseconds. About 12 nano seconds, actually. Quite long for such heavy particles.The charged kaons are composed of a strange quark and an antiup quark. Or an up quark and an anti-strange quark. Kind of like pions. Only STRANGE.Kaons are strange in more than the technical sense. Their decays confused everyone for quite some time.In the late 1940s, particle physicists discovered a few strange particles that all seemed to have about half the mass of the proton, but decayed very differently.Something physicists originally called the tau+ (a historical name, which should not to be confused with the tau lepton) decayed into THREE pions. A pi+ and two neutral pions. Something originally called the theta+ also decayed into pions, but only one pi+ and ONE pi 0. Confusingly, these taus and theta appeared to be IDENTICAL otherwise. They should have been the same, actually, except for those different decays. And up until that time, no particle had ever been seen decaying to BOTH two AND three pions.How could the tau+ and the theta+ be the same particle? It would be as if you were BOTH totally left handed AND totally right handed. Like you were literally your reflection in your mirror, but only sometimes. These ideas are captured by the idea of PARITY, nothing more than a twist on the idea of left and right handedness. Decaying to THREE pions suggested that the kaon parity was ODD. But decaying to TWO pions suggested it had even parity. Numbers can't be BOTH EVEN AND ODD, how could particles?This might seem like an abstruse problem to have, but to physicists at the time, conservation of parity seemed as vital as the conservation of angular momentum. We know better now, as kaon decay involves strange quarks which each via the weak nuclear force. The weak nuclear force - carried by W and Z-bosons - violates parity explicitly. Maximally, as it turns out.The charged kaons decay to muons about 63% of the time. Those two pion decays? That's just over 20%. The three pion decays? Just about 5.6%. There are crazy things too, like the so-called semileptonic decays which include BOTH pions AND electrons or muons. Things get complicated when the masses get large. But this is only the tip of the strangeness iceberg. There's plenty more to come.

Get in touch.Strange QuarksQuarks make up baryons like the proton and the neutron. Or more exotic things like the Lambda0 or the Delta++. Previously, we've learned about the up and down quarks - those fundamental constituents of matter like protons and neutrons. Today we're learning about the third of the three light quarks - the strange quark!The stability of quarks against decay is a quirky thing to talk about because the context matters a lot. One of the down quarks in the neutron will decay - in about fifteen minutes or so - to an up quark, shooting out an electron and leaving behind a proton. But that's only if the neutron is alone. If its bound together with a proton in an atomic nucleus, it is stable.The strange quark will also decay - also typically to an up quark - and it's lifetime also depends on the context. The Lambda baryon - like the proton - is a big bag of nuclear goo with three quarks banging around inside. It has an up, a down and a strange quark.The thing about strange quarks is: particles that contain one tend to live longer than you'd expect.The reason for this? There are a few. First, it necessarily decays via the weak force, which is always slower to move. But it's worse than that. There's just not much for a strange quark to decay into. Heavier particles can only decay into lighter particles, and the strange quark is just not heavy enough to provide many good options. There is literally one option: the up quark. To decay into an up quark, strange quark must emit a W-boson. It must behave like a down quark. The window for that decay is small! It might be 13 percent the size of a down quark. But between us, it's kind of surprising that this happens at all! That 13 percent suppression is related to something astonishing called the Cabibbo angle, which we'll come to at the end of the season. In any case, getting the right window to decay to an up quark takes awhile, which is why strange particles tend to live so long.Just like it's awkward to talk about the lifetime of a strange quark, it's also awkward to talk about it's electric charge. Quarks always show up in groups - and its their collective, electric charge that matters - but for the bean counters out there, the strange quark has an electric charge of minus 1/3. Just like the down quark.In a lot of ways, the strange quark is just a heavy version of the down quark.How heavy? Fairly. Compared to the humble 4.7 MeV of the down quark, the strange quark's mass is around 95 MeV.It's possible - in some corners of our universe - that strange quarks could be stable. But this is probably only true at stupidly high pressure. For example, It's possible that they exist inside neutron stars. Neutron Stars are what's left over after a star goes supernova. A fragment. A tight ball of matter that fell in on itself. Without the constant outward pressure given by a star's normal nuclear furnace, what's left of star falls inward, pulled together by gravity. Neutron star matter so tightly bound it's basically like one titanic nucleus. These are stars that are just on the precipice of becoming black holes.In this context. It is possible that the strange quarks can exist stably. For the experts, the Pauli Exclusion principle creates an effective, statistical pressure - modeled say by the Lennard-Jones potential - on the up and down quarks in the neutron star that can be relieved - in part - by the inclusion of strange quarks to literally mix things up.At least, that's what the models say. Whether we'd ever be able to test those models directly, is another matter.

Get in touch.For more technical details on the Lambda 0 baryon, including how why it decays to an up but not a down quark, check out this short, informal video.The Lambda 0 BaryonWith a mass of well over 1115 mega electron volts, about 20 percent more than the proton, the Lambda 0 is a rare, but historic particle to find.Inside the Lambda Baryons you'll find an up quark, a down quark and… something else. The first Lambda Baryon was first observed in 1950. In what amounts to a weather ballon. Way up high in the atmosphere. On a photographic emulsion plate. Particle physics was a different game back then!Physicists KNEW it was a baryon because it decayed into a proton. And it was heavy.Heavy particles decay quickly, and the Lambda was heavy. But it did not decay quickly enough. It stayed around for quite a while, a bit less than a nanosecond, which is rather long by particle physics standards. Especially for a baryon.Very strange. The long lifetime of the Lambda 0 was so strange that physicists knew there was something special about that particle. It had a special property. And in the 50's this new property of particles was showing up in more and more experiments. Because they had no idea what it could be, that called this property strangeness. For better or for worse, that technical name stuck.The new particle that makes up the Lambda 0 baryon is called a strange quark, and we'll visit them soon enough. Suffice it to say, a Lambda 0 baryon is composed of an up quark and a down quark and a strange quark.The Lambda 0 has no electric charge. It typically decays to either a proton or a neutron. If it's a proton - which happens about 63 percent of the time, it spits out a negative pion in the process. If it's a neutron - which accounts for most of the rest of the decays - it spits out a neutral pion instead.Using this quark model, we can explore the decay of the Lambda 0 in sharper detail.Inside the Lambda 0, the strange quark decays into an up quark, which converts that big bag of nuclear go into that proton or neutron. To do that, it must emit a W boson. Those familiar force carriers then decay into to a pion. As per usual.The Lambda 0 was just the first of the strange family of particles to be discovered. This entire season will be devoted to these strange particles.

Andrey Golutvin is a Professor at Imperial College London, Doctor of Physics and Mathematics. He is a globally renowned specialist in the area of elementary particle physics. Under his direct guidance, a series of studies of third-generation lepton features were conducted, and B-meson oscillations were discovered. A large value of B-meson oscillations opens up great opportunities for examining the phenomenon of CP-parity non-preservation, which resulted in creating specialized B-mezon factories and installing LHCb on the Large Hadron Collider (LHC) in the European Nuclear Research Organization (CERN).

Andrey Golutvin is a Professor at Imperial College London, Doctor of Physics and Mathematics. He is a globally renowned specialist in the area of elementary particle physics. Under his direct guidance, a series of studies of third-generation lepton features were conducted, and B-meson oscillations were discovered. A large value of B-meson oscillations opens up great opportunities for examining the phenomenon of CP-parity non-preservation, which resulted in creating specialized B-mezon factories and installing LHCb on the Large Hadron Collider (LHC) in the European Nuclear Research Organization (CERN). He made a significant contribution to developing the methodologies of fast, radiation-protected scintillation electromagnetic calorimeters. Under his direct guidance, the LHCb unit was successfully launched, and several most exact results of checking a standard model in heavy quark decays globally were obtained. He is a regular speaker at international conferences, including with his plenary reports at the largest, so-called Rochester Conferences on High Energy Physics in 2000 and 2010. He gave lectures at the Department of Elementary Particle Physics at MIPT and currently gives lectures at Imperial College London as a professor for the Department of High Energy Physics.Andrey focused on searches for new fundamental particles which are very weakly-interacting. Motivated by the lack of evidence for new heavy particles, he proposed the Search for Hidden Particles (SHiP) experiment to search for light, new particles in 2013 and this is currently his main research activity.The SHiP experiment has a window of opportunity to lead to fundamental findings on a timescale of < 10 years. The potential discovery of New Physics by SHiP may lead to a complete change of direction in high energy physics and, in particular, may prove that newhigh energy colliders are not needed to uncover the origin of neutrino masses, dark matter, and baryon asymmetry of the Universe.SHiP has instigated a number of pioneering developments that make it possible to construct a large-scale, background-free, high-precision detector operating in beam-dump mode with the full power of the SPS accelerator at CERN. This puts SHiP in an outstanding position world-wide to make a break-through in the domain of particle masses and couplings that are not accessible to the energy and precision frontier experiments, and potentially find the particles that lead to neutrino masses and oscillations, explain baryon asymmetry of the Universe, and shed new light on the properties of dark matter.SHiP has received a large amount of attention from the particle physics community ever since its inception. In the 2019-2020 update of the European Strategy for Particle Physics, Dark Matter and Feebly Interacting Particles took a prominent position for the first time, and SHiP was ranked as a mature and competitive project ready for implementation. The preparatory evaluation of experiments complementary to the high energy frontier, singled out SHiP and the associated Beam Dump Facility (BDF) as a major potential player in the search for Feebly Interacting Particles.SHiP is currently a collaboration of 53 institutes and 4 associated institutes, in total representing 18 countries, CERN and JINR. Currently, SHiP's central challenge consists in finding the resources required to take advantage of the time-limited opportunity that exists to launch SHiP's data-taking before the end of this decade. The total cost of the project is about 220 MCHF, including 150 MCHF for the Beam Dump Facility and 70 MCHF for the SHiP detector.CERN committees have endorsed the SHiP science case. In order to obtain the seal of approval to the project and start the construction of the BDF, three key concepts have to be proven with prototypes, namely the ultra-high efficiency for slow extraction and delivery of the SPS beam, the extreme conditions for the high-density proton target, and the unprecedented background suppression through the use of an active muon shield. The CERN Medium Term Plan of this year allocates sufficient resources to complete the R&D studies of the beam line and the target. The construction of the muon shield prototype and study of its performance is led by the group from Imperial College London and requires funding at the level of ~3 MCHF during next 2-3 years

Hello and welcome to another episode of the Dongfang Hour China Aero/Space News Roundup! Our sincere apologies for the late upload of this episode, due to technical issues. Without further ado, the news update from the week of 7-13 December.1) iSpace making progress in the development of Hyperbola 2iSpace announced that they had completed the production of the fuel tank for the Hyperbola-2 rocket. The company’s Hyperbola-2 will use liquid methalox fuel, and is China’s first common bulkhead fuel tank for rockets above 3m diameter. iSpace also completed a week earlier a series of supersonic wind tunnel tests for the vertical landing phase, a crucial moment of the flight with complex aerodynamics and instability. 2) Launch of Long March 11 with 2 CAS satellitesLast week, China saw a launch of a Long March 11 rocket, the 3rd launch of such a rocket in China in 2020. This launch received less cover overall, as it concurred with the Chang’e 5 hype that was taking place at the same time.This launch of LM-11 took place at Xichang on the 9th of December, and put into orbit 2 smallsats of the GECAM mission (aka Gravitational Wave High-energy Electromagnetic Counterpart All-Sky Monitor), and initiated by the CAS Institute of High Energy Physics in Beijing.Designated KX-08A and KX-08B, each satellite will embark a number of instruments to detect gamma/x wave bursts in the universe.3) Great article on C919 SuppliersThe Center for Strategic & International Studies (CSIS), a think-tank based in DC, published on Dec. 7 a good piece on the Chinese commercial aviation industry, and notably on the poor performance of COMAC, from both an industrial and technical point of view.According to CSIS, while China admittedly has done admirably in turning itself into a high-tech superpower in a number of industries, commercial aviation is not part of them.To justify this point, CSIS points to some of the recurring problems of COMAC, including:- The poor performance of COMAC A/C- The significant delays that the programs have experienced- The poor industrial productivity (based on the annual production rate)- The troubles with certification- And its reliance on foreign suppliersAll in all, a great piece that we recommend to our viewers, although admittedly we feel that in some areas the paper is overly pessimistic/negative about Chinese commercial aerospace.4) National Radio and Television Administration AnnouncementChina’s NRTA announced this week plans for modernization of the country’s broadcast sector. This includes several key phrases, namely “smart business”, “UltraHD/4K”, and also “Satellite internet/converged two-way services” (融合双向业务). The announcement also hits on the convergence of TV and internet access, that is, most TV can be delivered via internet access. Other points of note in the announcement included a call to build a cloud platform for satellite broadcast (建设直播卫星云平台), and to develop “two-way communications” for satellite broadcast that allow for things like online shopping, smart homes, and digitization of small towns.Overall, the announcement should be taken as an indication that China wants to modernize its relatively archaic linear broadcast industry. 5) Dongfang Hour reaches 100+ subscribers!Last but not least, the Dongfang Hour channel has reached 100+ subscribers this week, with a 10% jump in the last few days. While this remains a modest figure, we would like to address a big thanks to our viewers for their support, and hope to bring more valuable content on Chinese aerospace and tech in 2021! ---------------------------------------------Follow us on YouTube, LinkedIn, Twitter (https://twitter.com/DongFangHour), as an audio podcast, and on our official website: https://www.dongfanghour.com/

The first is that AI and robots will take over the world and the second is that we are so far away from this reality we have enough time to make sure this doesn't happen. In my conversation with Dr Sofia Vallecorsa we discuss her work at Cern, home of the Large Hadron Collider. Sofia's extensive experience in software development in the High Energy Physics domain, in particular on Quantum Computing and Deep Learning applications makes for a very interesting conversation on the future of AI.

Antonio EreditatoEdoardo Boncinelli"L'infinito gioco della scienza"Come il pensiero scientifico può cambiare il mondoIl Saggiatorehttp://ilsaggiatore.it/Nell'era della superficialità dell'informazione, in cui imperversano le fake news e al ragionamento critico si antepongono presunzione e ignoranza, la scienza sembra essere sotto attacco. Ma non è che un paradosso, perché mai come oggi la ricerca scientifica è stata così forte e affidabile.Edoardo Boncinelli e Antonio Ereditato, due scienziati italiani in prima linea nei rispettivi campi di indagine – la genetica e la sica delle particelle –, ci raccontano che la scienza è bellezza, creatività, gioia della ricerca e della scoperta. È indagare e comprendere i misteri della natura, è lo sforzo di evocare nelle nostre menti l'universo intero. In fondo, la scienza è un gioco. Un gioco intellettuale e materiale, faticoso eppure attraente, in cui si procede per tentativi ma secondo regole ferree, in cui ogni conclusione è sempre provvisoria e il rincorrersi virtuoso tra teorie e osservazioni porta a risultati sorprendenti. E non sono soltanto le applicazioni della ricerca scientifica a cambiare il mondo in cui viviamo e il nostro modo di pensarlo; è l'atto stesso del ricercare che lo modifica, introducendo novità e trasformazioni di ogni tipo.L'infinito gioco della scienza ci svela che il potere della scienza è proprio questo: la capacità di plasmare la realtà e di partecipare alla sua costante ricreazione. Una partita che Boncinelli ed Ereditato ritengono troppo emozionante per essere abbandonata: si resta in campo, quindi, a giocare il fantastico e infinito gioco della scienza.Edoardo Boncinelli è il più importante genetista italiano. Per più di vent'anni ha svolto attività di ricerca presso l'Istituto di genetica e biofisica del cnr di Napoli. È stato direttore del Laboratorio di biologia molecolare dello sviluppo presso l'Università San Raffaele e direttore di ricerca presso il Centro per lo studio della farmacologia cellulare e molecolare del cnr di Milano.Antonio Ereditato è professore di Fisica delle particelle elementari presso l'Università di Berna e direttore del Laboratory for High Energy Physics e dell'Albert Einstein Center for Fundamental Physics sempre a Berna.

The Sun (in common with other stars) is a fusion engine that turn protons by a series of processes into helium, emitting energy in the process, with about half of the Sun's protons captured so far. Hydrogen atoms, stripped of electrons, are single protons which can be accelerated to smash other nuclei and have applications in proton therapy.

Bioinformatics and more widely Computational Biology is a largely data-driven Science. The array of high-throughput technology platforms in the last 10 years mean that the amount of data being generated in this field is likely to enter into Exabytes by 2020. The challenges associated with this are quite different from the data sets generated by High Energy Physics or Astrophysics in that they tend to gathered from a wide variety of different providers. Meta-analyses of these data sets can give startling new insights but come with many caveats - in particular that the quality of the data from each provider can be highly variable. I will spend some time talking about one set of experiences I have dealing with one specific technology platform and in particular how it is clear that the detection of bias in data sets is a key element of any high-throughput analysis.

He has been on Coast to Coast Am w/George Noory.Dr. Piccioni has a B.S. in Physics from Caltech, a Ph.D. in High Energy Physics from Stanford University, was a faculty member at Harvard University.We live in the Golden Age of Astronomy. More has been learned in our lifetime about stars, galaxies, black holes and the Big Bang than in the entire prior history of mankind.Two award-winning books: 1. Can Life Be Merely An Accident? 2. Everyone's Guide to Atoms, Einstein, and the Universe. His website is www.guidetothecosmos.com Also Author Peter Kling will be with us at 11 pm.Considered as the Einstein of Biblical prophecy: Mr. Kling started being taught Bible Prophecy from the age of 5. He had his first prophetic dream at 9. Started being educated in science and chemistry at the age of 10. Had "Contact" at 18. Studied Metaphysics at 22. Started scientific based research on the Biblical record in 1985, (still in process). 2009 authored "Letters to Earth You Can Survive Armageddon!" "Mr. Kling has combined his scientific and religious education together, to uncover the "mystery" that religion has tried to keep hidden for over 2000 years."

Melvyn Bragg and guests discuss Antimatter, a type of particle predicted by the British physicist, Paul Dirac. Dirac once declared that “The laws of nature should be expressed in beautiful equations”. True to his word, he is responsible for one of the most beautiful. Formulated in 1928, it describes the behaviour of electrons and is called the Dirac equation. But the Dirac equation is strange. For every question it gives two answers – one positive and one negative. From this its author concluded that for every electron there is an equal and opposite twin. He called this twin the anti-electron and so the concept of antimatter was born.Despite its popularity with Science Fiction writers, antimatter is relatively mundane in physics – we have created antimatter in the laboratory and we even use it in our hospitals. But one fundamental question remains – why isn't there more antimatter in the universe. Answering that question will involve developing new physics and may take us closer to understanding events at the origin of the universe. With Val Gibson, Reader in High Energy Physics at the University of Cambridge; Frank Close, Professor of Physics at Exeter College, University of Oxford; Ruth Gregory, Professor of Mathematics and Physics at the University of Durham
