Strengthening the full implementation of the Treaty on the Non-Proliferation of Nuclear Weapons necessitates a balanced implementation of all of its three pillars: nuclear disarmament, non-proliferation of nuclear weapons, and peaceful nuclear uses. However, the current geopolitical situation has exacerbated significant challenges in all of these three pillars. In his address to the IIEA Ambassador Klement discusses efforts to address those challenges, and reflects upon regional non-proliferation crises and his experience as a negotiator in the Iran nuclear negotiations. Speaker bio: Ambassador Stephan Klement is the EU Special Envoy for Disarmament and Non-Proliferation, a position he has held since February 2024. From 2019 to 2023, Ambassador Clement served as EU Head of Delegation to the International Organisations in Vienna. Since 2016, he has served as the Special Advisor for the Iranian nuclear issues in the European External Action Service (EEAS). Mr. Klement holds a Doctoral degree in International Law from the Institute of International Law and International Relations, University of Vienna. He holds a Doctoral degree in Physics from the Institute of Experimental Physics, University of Vienna, a Masters in Law and a Masters in Theoretical Physics both from the University of Vienna, Austria.
Welcome to the 79th episode of “Decode Quantum”. We continue our “international episodes”, this times with the cofounders of the US startup EeroQ, Nick Farina and Johannes Pollanen, which aims to create qubits with electron spins, electrons being shielded from controlling electronic circuits by a layer of superfluid helium. This is the only company doing this. Nick Farina is the CEO and co-founder of EeroQ in 2017. Beforehand, he worked as an business angel investor, and an entrepreneur, launching multiple tech startups (GiftedHire for online job search, Voltage Digital a digital agency, JetZet providing itinerary management tools to business travelers). He's the one bringing business acumen to the company. He is also a Quantum Computing Governance Member at the World Economic Forum since 2021. In 2000-2003, he was a caddie at a golf club (Biltmore Country Club) where he spent summers watching people cheat at golf and lament their losses in tech stocks. Johannes Pollanen is a co-founder and the Chief Science Officer of EeroQ. He is a researcher from Michigan State University (MSU) where he holds the Cowen chair of Distinguished Chair in Experimental Physics. He is also Associate Director of the MSU Center for Quantum Computing Science and Engineering. He runs the Laboratory for Hybrid Quantum Systems, which is focused on hybrid quantum technologies involving superconducting qubits, superfluids, trapped electrons, and other condensed matter systems. He developed the EeroQ electrons on superfluid helium architecture. He did his PhD at Northwestern University with Bill Halperin and contributed to the discovery of new quantum phases in superfluid helium-3, which influenced his later work in designing quantum computing platforms. He then was a post-doc at Caltech, with Jim Eisenstein, working on exotic many-body states in ultra-clean semiconductor systems.And as usual the transcript : https://www.oezratty.net/wordpress/2025/decode-quantum-with-nick-farina-and-johannes-pollanen-from-eeroq

Why are girls discouraged from doing science? Why do so many promising women leave science in early and mid-career? Why do women not prosper in the scientific workforce? Not Just for the Boys: Why We Need More Women in Science (Oxford UP, 2023) looks back at how society has historically excluded women from the scientific sphere and discourse, what progress has been made, and how more is still needed. Athene Donald, herself a distinguished physicist, explores societal expectations during both childhood and working life using evidence of the systemic disadvantages women operate under, from the developing science of how our brains are―and more importantly aren't―gendered, to social science evidence around attitudes towards girls and women doing science. It also discusses how science is done in practice, in order to dispel common myths: for example, the perception that science is not creative, or that it is carried out by a lone genius in an ivory tower, myths that can be very off-putting to many sections of the population. A better appreciation of the collaborative, creative, and multi-disciplinary nature of science is likely to lead to its appeal to a far wider swathe of people, especially women. This book examines the modern way of working in scientific research, and how gender bias operates in various ways within it, drawing on the voices of leading women in science describing their feelings and experiences. It argues the moral and business case for greater diversity in modern research, the better to improve science and tackle the great challenges we face today. Athene Donald is Professor Emerita in Experimental Physics and Master of Churchill College, University of Cambridge. Other than four years postdoctoral research in the USA, she has spent her career in Cambridge, specializing in soft matter physics and physics at the interface with biology. She was the University of Cambridge's first Gender Equality Champion, and has been involved in numerous initiatives concerning women in science. She was elected Fellow of the Royal Society in 1999 and appointed DBE for services to Physics in 2010. Morteza Hajizadeh is a Ph.D. graduate in English from the University of Auckland in New Zealand. His research interests are Cultural Studies; Critical Theory; Environmental History; Medieval (Intellectual) History; Gothic Studies; 18th and 19th Century British Literature. YouTube channel.

Not Just for the Boys: Why We Need More Women in Science (Oxford UP, 2023) looks back at how society has historically excluded women from the scientific sphere and discourse, what progress has been made, and how more is still needed. Athene Donald, herself a distinguished physicist, explores societal expectations during both childhood and working life using evidence of the systemic disadvantages women operate under, from the developing science of how our brains are―and more importantly aren't―gendered, to social science evidence around attitudes towards girls and women doing science. It also discusses how science is done in practice, in order to dispel common myths: for example, the perception that science is not creative, or that it is carried out by a lone genius in an ivory tower, myths that can be very off-putting to many sections of the population. A better appreciation of the collaborative, creative, and multi-disciplinary nature of science is likely to lead to its appeal to a far wider swathe of people, especially women. This book examines the modern way of working in scientific research, and how gender bias operates in various ways within it, drawing on the voices of leading women in science describing their feelings and experiences. It argues the moral and business case for greater diversity in modern research, the better to improve science and tackle the great challenges we face today. Athene Donald is Professor Emerita in Experimental Physics and Master of Churchill College, University of Cambridge. Other than four years postdoctoral research in the USA, she has spent her career in Cambridge, specializing in soft matter physics and physics at the interface with biology. She was the University of Cambridge's first Gender Equality Champion, and has been involved in numerous initiatives concerning women in science. She was elected Fellow of the Royal Society in 1999 and appointed DBE for services to Physics in 2010. Morteza Hajizadeh is a Ph.D. graduate in English from the University of Auckland in New Zealand.

The Field Guide to Particle Physics : Season 3https://pasayten.org/the-field-guide-to-particle-physics©2022 The Pasayten Institute cc by-sa-4.0The definitive resource for all data in particle physics is the Particle Data Group: https://pdg.lbl.gov.Also check out the links embedded this description. Or also check out those same links at:https://pasayten.org/the-field-guide-to-particle-physics/antineutrinoThe Pasayten Institute is on a mission to build and share physics knowledge, without barriers! Get in touch.The AntineutrinoThe neutrino is a curious particle. As fundamental as the electron or the muon, but rarely interact with other particles. This makes the study of these neutrini quite challenging. But also quite interesting.Are there antineutrini? Yes, surely. But, a better question is what are antineutrini?Antiparticles with an electric charge are easier to identify. Positrons and electrons have opposite charges and behave oppositely in most respects. Photons and neutral pions do not have any electric charge. They are their own antiparticle partners! But this isn't always the case with neutral particles. As we have antineutrons and two distinct kinds of neutral kaons: the K0 and K0bar which are antiparticles of each other.Neutrini - those smallest of massive matter particles in the Standard Model - are electrically neutral. So it is natural to ask: are they their own antiparticle? Or are there distinct antineutrini? And importantly, how can we tell the difference?The short answer is, we don't know yet. End of story. But the short answer is boring.Neutrini are famously shy and interact only via the weak nuclear force - and gravity - so detecting them so detecting them is no small task.So without further ado, let's go ahead with the long answer.Beta DecayNeutrons decay to protons by emitting an electron. This is usually called beta decay, and is mediated by the W- boson. Other nuclei experience it as well. Detailed studies of beta decay suggest that the neutron should decay into two particles rather than one. That second particle was need to make sure that energy, momentum and spin angular momentum was conserved. As it should be.The neutrino - the small neutral one - was discovered nearly 26 years after their proposal.Now, electric charge is conserved in beta decay. The uncharged neutron decays to a positively charged proton and a negatively charged electron and a neutrino. The neutrino also has no electric charge, but carries away some of the energy and some of the momentum.So far as we can tell, energy, momentum and spin like electric charge, is always conserved. Such conservation laws are useful organizing principles for understanding the laws of particle physics. Some might argue they are foundational.Another thing that seems to be conserved in nature - usually anyway - is the number of leptons in the universe. There are actually quantum effects that can change the number of leptons, but in ordinary decays - like beta decay - they seem to conserve the number of leptons.Neutrini - like electrons, muons and taus - are leptons. Naively you might think that beta decay creates two leptons: a neutrino and an electron. The thing is, the neutron actually emits an electron and an antielectron neutrino. Like electric charge, antineutrinos count as minus one lepton.The math also works in reverse. If a nucleus absorbs an electron - which sometimes happens in certain isotopes of Vanadium, Nickel and Aluminum - it will convert a proton to a neutron, and spit out a regular neutrino. Conserving the number of leptons.Now, before your eyes glaze over, I know. Talking about weird conservation rules like lepton number is tricky, because it seems like a bunch of silly rules the details quickly spiral out of control. Neutrino physics is nothing if not complicated.So let's talk more about some of the reactions.Flavors of AntineutriniEach electrically charged lepton: the electron, the muon and the tau, has it's own flavor of neutrino. There's an electron neutrino. A muon neutrino and a tau neutrino. Each electrically charged antilepton also has its antineutrino partner: antielectron neutrino. anti muon neutrino. Anti tau neutrino.When a muon decays into an electron, it actually emits three particles: the electron, the antielectron neutrino and a regular muon neutrino.Given that there are so many cosmogenic muons around us, muon neutrinos - and anti electron neutrinos - are also fairly ubiquitous here on Earth.And of course you might remember the famous experimental result that neutrinos can change their flavor as they move. So neutrinos flavors can get all mixed up, just like antineutrino flavors can get all mixed up. But do neutrini get mixed up with antineutrini?They would if they were the same particle, wouldn't they? Let's think about it another way. In terms of annihilation. Do Neutrini and Antineutrini annihilate each other?When an electron and positron collide, a pair of photons usually comes out. The antiparticle partners annihilate into pure electromagnetic energy. What do you suppose happens when a neutrino collides with an antineutrino?A neutrino and an antineutrino - assuming it exists - would not annihilate to form photons. They have no electromagnetic charge and therefore no chance. They could potentially exchange a Z-boson, or even a Higgs Boson! Although the likelihood of the latter is proportional to the mass of the neutrini involved - and so very, very small.If a neutrino-antineutrino pair of the same flavor smashed against each other violently enough, a pair of Z-bosons could come out. And.. if the neutrino were its own antiparticle partner, well, then any two neutrini of the same flavor could do this!Such an annihilation of two regular electron neutrini would be strong evidence that the neutrino is its own antiparticle. But what a challenging experiment that would be! Where would you get dedicated, high energy neutrino beams?Instead, physicists are looking for a slightly easier measurement with a clear signature: neutrinoless double beta decay.Rarely, nuclei emit two electrons at time, converting their atomic number by changing two neutrons into two protons simultaneously. Germanium-76 and Xenon-136 are just a few of the many nuclei that undergo double beta decay.If neutrini are their own antiparticle partners, it's possible that those two electrons could come out, and the pair of neutrini would annihilate each other just as the decay happens.If no neutrini are produced, conservation of momentum suggests that the electrons will be emitted in opposite directions, and conservation of energy suggests that their energy should sum exactly to difference in atomic mass of the parent and child nucleus.To date, all double beta decays observed have been consistent with the emission of neutrini. Studies from experiments like EXO, NEMO, GERDA have shown that it takes nuclei over 10,000 times longer to decay without neutrini. But of course if it cannot happen - if the neutrino is NOT its own antiparticle in any capacity - then it never will.But the search is one. The CUORE and KamLand-Zen experiments are still taking data and nEXO is still be planned.Neutrino Masses and the SeesawFinally, we know that neutrini have tiny masses. Super tiny. A million times smaller than the electron, at least.If neutrini are their own antiparticle partners, they have a special kind of mass called the “Majorana” mass. If the antineutrini are distinct particles, then their mass might well be a “Dirac” mass - which is the usual kind mass that leptons pick up in the standard model. This distinction is of course reductive. There is no reason why they couldn't have both a Majorana mass and a Dirac mass.In fact, if they do have both, then there is a very natural explanation for why the neutrino mass is so small compared with all the other fundamental particles.If the Majorana mass is really, really big, say associated to some complicated physics we don't yet understand, and the Dirac mass is “normal” by comparison to other particles, like a few thousand electron volts, the combination of those two masses we experience actually appears as a ratio of the two, rather than the sum. This is the famous seesaw mechanism. Neutrini are the only electrically neutral, elementary fermions known to science. Quarks all have electric charges. Electrons, muons and taus all do too. It is perhaps no surprise that neutrino physics is uniquely complicated. And if there's one thing particle physics enjoys, it's being complicated.©2022 The Pasayten Institute cc by-sa-4.0
We often talk about climate change on this podcast. The IPCC deadline is hanging over our heads like the sword of Damocles. This week Steve talks to David Keith, a professor of both Applied Physics and Applied Policy at Harvard, and author of A Case for Climate Engineering. Climate engineering, a term for solar geoengineering or solar radiation modification, would enable us to alter the Earth's reflectivity and reduce some of the climate risks that come from accumulated carbon dioxide. Keith is quick to point out that this is not a silver bullet but should be considered as part of a multi-pronged strategy. Managing climate risk involves four basic actions: Cut emissions by decarbonizing the energy system Remove carbon dioxide from the atmosphere Solar radiation modification, or solar geoengineering Adaption to reduce the harms of climate change on crops, people, and ecosystems While there's no way to address climate change without replacing our energy system, it's not the entire solution. If we stop all CO2 emissions today, the climate problem won't improve, it will merely stop getting worse. We won't have reduced the amount of carbon in the atmosphere. Thus the case for climate engineering. The discussion includes the different roles for scientists and activists. They look at limitations, or flaws, in the IPCC report, and consider the importance of separating science from strategy. David Keith has worked near the interface between climate science, energy, technology, and public policy for 25 years. He took first prize in Canada's National Physics Prize exam, won MIT's Prize for Excellence in Experimental Physics, and is one of Time Magazine's heroes of the environment. He's a professor of Applied Physics at the Harvard School of Engineering and Applied Sciences, and professor of Public Policy at the Harvard Kennedy School and founder of Carbon Engineering, a company developing technology to capture CO2 from the ambient air to make carbon neutral hydrocarbon fuels. He is author of “A Case for Climate Engineering.” @DKeithClimate on Twitter
The Field Guide to Particle Physics : Season 3https://pasayten.org/the-field-guide-to-particle-physics©2022 The Pasayten Institute cc by-sa-4.0The definitive resource for all data in particle physics is the Particle Data Group: https://pdg.lbl.gov.The Pasayten Institute is on a mission to build and share physics knowledge, without barriers! Get in touch.The AntineutronLike the antiproton, the antineutron is a composite particle made up of antiquarks. It looks a lot like the neutron, and that's pretty interesting because both of those particles have no electric charge!The antineutron is made from two antidown quarks and an antiup quark. The antineutron's mass is a bit over 939 MeV, and the mass difference ratio between the neutron and the antineutron is essentially consistent with zero.Because it's electrically neutral, it is really hard to measure properties of the antineutron. You can't really use electric or magnetic fields to confine, shape or cool collections of antineutrons in any meaningful way.We don't have a working measurement of the antineutron's magnetic dipole moment. We haven't really studied their decay. Left to its own devices, the neutron decays in about 15 minutes to a proton, and electron and a neutrino. We'd expect the antineutron to decay similarly, but with a positron. But again. It's a serious experimental challenge. We barely have a handle on the antineutron's mass! But there have been experimental antineutron beams and there is still plenty of interesting physics that can be done with them.Antineutron beamsAntiproton and antineutron technologies are linked. The antiproton was discovered in 1955 , and the antineutron was found in 1956. In the 1980s, The Low Energy Antiproton Ring at CERN fired a slow beam of antiprotons at liquid hydrogen to create a secondary beam of anti neutrons.Low energy proton-antiproton collisions proceed by the exchange of a single pion. Because the hydrogen was kept super cold, and the antiprotons had such low energy, the two particles exchanged a single, virtual neutral pion, which afforded a conversion of the proton antiproton pair to a neutron antineutron pair.This secondary beam of neutron/antineutron pairs was aimed at an iron slab for a target. The neutron and antineutron interact with iron differently, but expecting to find both particles simultaneously made the measurement pretty tractable.Again. Antineutrons are hard to work with, so any trick you can find to help is welcome!AntinucleiOf course, there's more.Antineutrons have been created in atomic nuclei. Or antinuclei, if you like. Deuterium - a hydrogen atom with a bonus neutron in the nucleus has a theoretical antimatter cousin, antideuterium. The nucleus of anti deuterium was created in experiments way back in the 60s, although cooling those nuclei down enough to accept an orbiting positron has not yet occurred. But hey, ,antihydrogen was only really successfully studied in 2016!The relativistic heavy ion collider has observed the anti helium-4 nucleus. In other words, there's also an anti alpha particle!All these discoveries point to to the fact that there is very little difference between matter and antimatter, which makes the overall dearth of antimatter in our observed universe even more confusing.

Get in touch.AntiprotonsAntiparticles are everywhere. They're just part of life. The electron has its positron partner. Muons and antimuons are both routinely created in the upper atmosphere. They're so familiar that we often just call them mu plus or mu minus. The antiparticle nature of mu plus just isn't that big a deal.If you've been paying attention to our series, you know we've talked about antiparticles quite a bit, at least in passing. Up and down quarks sometimes associate with anti-up and anti-down quarks to form pions. Other mesons like kaons form similar quark-antiquark pairs.It's fun to see composite particles made up from particles and antiparticles. The neutral pion - for example - is a bound state of particle/anti particle partners - uubar & ddbar - not unlike positronium: where an electron and a positron orbit each other like an atom. Of course, all these composite particles are unstable.Arguably what separates antimatter from antiparticles is finding a composite particle that is stable. Or at least really long lived. Something that looks and behaves like ordinary matter. Something like atoms.Enter the antiproton.Just like the proton, the antiproton is a tiny bag of subnuclear goo. Virtual pions and gluons and other quantum effects are all dressed up in the antiproton package around three valance antiquarks. That's two anti-up quarks and one anti-down quark. The antiproton looks virtually identical to the proton - except that it has a negative electric charge.Like the proton, the antiproton has a mass of about 931 MeV. In fact, it's difference from the proton's mass has been measured, and at present it looks like they're the same up to less than one part in a million!In fact, everything they measure from the antiproton seems to to line up exactly with the proton. The magnetic moment - a measure of a little dipole magnetic field generated by the anti proton - still appears to be equal and opposite to that of the proton.AntihydrogenAnd yes, the negatively charge antiproton can pick up a positively charge positron and form an atom. Like hydrogen. You know, Antihydrogen! Antihydrogen has been studied and confirmed to look and behave exactly like hydrogen. The positron energy levels of thes anti atom and the associated electromagnetic spectra are all the same. Even the fancy, hyperfine splitting of those energy levels have been experimentally shown to be identical with ordinary hydrogen, at least up to experimental precision.Antiproton decayBy all observations so far, the proton appears to be a stable particle. If the proton did decay, it would be big news and a boon for folks looking to study physics beyond the standard model.The antiproton - so far as we can tell - is also stable. Which is good - our theory is self consistent - but it does present the question: if they don't decay, then where are all the antiprotons in nature?!Sources of antiprotonsNobody knows why there's so little antimatter in the universe, but there definitely is some.Antiprotons impinge upon the Earth's upper atmosphere all the time. They're secondary cosmic rays that currently appear to be associated with super high energy protons smashing into gas and other material sitting in between the stars in our own galaxy. It's a by-product - in other words - of cosmic ray collisions. We can make them here on Earth too. The ALPHA experiment at CERN has an antiproton source made by smashing protons into iridium. The Tevatron at FermiLab had an antiproton source that used Nickel instead.The Tevatron was an interesting particle accelerator in that - unlike the LHC, which colliders protons together - the Tevatron collided protons against antiprotons, to give it a little extra boost in energy from quark-antiquark annihilation when those two, composite particles collided.The fact that there is so much more matter in the universe than antimatter means that antimatter is simply going to annihilate against any matter that it runs into. But how protons and antiprotons annihilate is a complicated issue.Antiproton annihilationElectrons and positrons annhilate cleanly into a pair of gamma rays. The antiproton and the proton do not cleanly annihilate. There is no easy, super clean signal when they annihilate. They're composite particles. Worse, they're both really messy composite particles.Typically what happens when a proton meets an antiproton is that one of the quarks meets up with one of the antiquarks and interacts from there. All kinds of particles can come out, things like pions, more protons, and other emissions from the subnuclear goo. The details all depend on how quickly those particles are moving when they meet each other.If they're moving slowly, their quantum clouds of subnuclear goo might overlap, and a pion might be exchanged. If they're moving quickly, like they were at the Tevatron, those antiquarks - who carry the highest fraction of the antiproton's momentum - will collide with the quarks in the proton, and all kinds of things can - and have! - come out.

My guest on this occasion is Jean-Yves Tinevez, research engineer and head of the image analysis hub at the Institut Pasteur. I have the great privilege of now considering Jean-Yves a friend. However, some years ago, I was just a fan of his work, particularly trackmate. His reaction to me letting him know of this small piece of history was a true testament to his character. Jean-Yves is brilliant, loves the community he is part of, and conducts himself with great humility, he even reveals in our conversation some of the ways in which he checks his ego, making sure it does not grow more than he sees fit. We go over many topics, discussing his love for experimental physics, how the need for better measurements and his personal skill sets drove him to develop trackmate, and how trackmate and other software he developed and maintains have evolved to tools used by the bio-image analysis community at large. I hope that you find this conversation as interesting as I did.

Eric Cornell in conversation with Priyamvada Natarajan. The notion of imperfection usually carries negative implications and the idea of defect. But what is the significance and implication of the concept of imperfections in the field of physics? How did it impact our universe? Eric Cornell, Professor of Experimental Physics from the University of Colorado and Nobel Laureate for Physics in 2001, speaks with distinguished astrophysicist Priyamvada Natarajan and evaluates the one moment in time 14 billion years ago that made it possible for us to be here today. This episode is the audio version of a live online session from #JLFColorado2020.
Joel Sherrill (JoelSherrill) spoke with us about choosing embedded operating systems and why open source RTEMS (RTEMS_OAR) is a good choice.

We are introduced to the show by Russ Willard (Jonathan Pryce), the founder of the Mercer Center for Experimental Physics, nicknamed by the local Ohio residents as "The Loop." He explains The Loop exists to unlock and explore the mysteries of the universe, and that everyone is connected by it, so we begin one of many stories with the local residents. Loretta (Abby Ryder Fortson), a bright young girl, comes home from school to hear her mother, Alma, has stolen a piece of The Eclipse, the power source of the Loop, to conduct an experiment. That next day, after recieving outstanding marks on a math test, Loretta heads to the MCEP to surprise her mother with the good news, but does not find her. In her search for Alma, she discovers an unusual rock that she can float in the air, befriends a boy named Cole (Duncan Joiner), meets his family, but finds no trace of Alma. She only finds her math test tucked in a box of trinkets owned by Cole's mother, also named Loretta (Rebecca Hall). The older Loretta later makes this realization and seeks out her younger self to explain the phenomenon she had misremembered as a dream and come to terms with the unexplained disappearance of her mother. She brings young Loretta into The Loop to return the lost fragment of The Eclipse, thus returning her younger self to her time and reminding her present self to reconcile with her own child.

While glass items have been made for at least 5,000 years, scientists are yet to explain, conclusively, what happens when the substance it's made from moves from a molten state to its hard, transparent phase. It is said to be one of the great unsolved problems in physics. While apparently solid, the glass retains certain properties of a liquid. At times, ways of making glass have been highly confidential; in Venice in the Middle Ages, disclosure of manufacturing techniques was a capital offence. Despite the complexity and mystery of the science of glass, glass technology has continued to advance from sheet glass to crystal glass, optical glass and prisms, to float glasses, chemical glassware, fibre optics and metal glasses.

Dimensions. Reflecting on dimensions has a long history in popular culture, from the geometrically minded satirical novella Flatland: A Romance of Many Dimensions by Edwin A. Abbott to the 1937 film The Fourth Dimension by director Jean Painleve. But how is the relationship between different dimensions explored in the Star Trek universe? From a plane of two-dimensional beings in the Star Trek: The Next Generation episode "The Loss," to higher-dimensional beings like members of the Q continuum with their ability to pop in and out of three-dimensional space at will, Star Trek is replete with examples of dimensional interplay. In this episode of Meta Treks, hosts Mike Morrison and Zachary Fruhling are joined by Trek.fm Patreon manager and host of Melodic Treks and Warp Five, Brandon-Shea Mutala, to discuss the physics, the philosophy, and the geometry of dimensions in the Star Trek universe.

Dame Athene Donald is one of our leading physicists, and an outstanding role model and campaigner for women in science. She is Master of Churchill College, Professor of Experimental Physics at the University of Cambridge, and as the new head of the British Science Association, she has already made waves suggesting that girls should be given Meccano in preference to Barbie dolls to encourage them into science. It's physics with a clear practical end - the physics of the everyday - which is her passion. Her expertise lies in developing techniques to study 'soft' materials: the way paint particles stick together, or what happens to things when you cook them, or more recently, the generic way protein molecules stick together, which, for some very specific proteins, is the process which underlies Alzheimer's disease. A life-long promoter of women in science, she is a recipient of the L'Oreal-UNESCO Award for Women in Science in Europe and writes a popular and entertaining blog about science, women, the wider world, and sometimes music too. A talented viola player, she considered a career in music as a teenager, and her choice of music reflects her continued love of the instrument: Bach's 6th Brandenburg Concerto, Janacek's Second String Quartet, known as 'Intimate Letters', and Mozart's Sinfonia Concertante for violin and viola which she played with her husband, a mathematician - and violinist. Keen to promote women in music as well as women in science, she's also chosen music by the French composer Lili Boulanger. Producer: Jane Greenwood A Loftus Production for BBC Radio 3.

Melvyn Bragg and his guests discuss the science of matter and the states in which it can exist. Most people are familiar with the idea that a substance like water can exist in solid, liquid and gaseous forms. But as much as 99% of the matter in the universe is now believed to exist in a fourth state, plasma. Today scientists recognise a number of other exotic states or phases, such as glasses, gels and liquid crystals - many of them with useful properties that can be exploited. With: Andrea Sella Professor of Chemistry at University College London Athene Donald Professor of Experimental Physics at the University of Cambridge Justin Wark Professor of Physics and Fellow of Trinity College at the University of Oxford Producer: Thomas Morris.

When she started her career, physicist Dame Athene Donald took a decision that shocked her colleagues. She wanted to apply the strict rules of physics to the messy, complicated world of biology. Since then, she has taken the field of biological physics out of an unfashionable rut in the 1980s, and helped to turn into one of the most exciting and promising areas in science today. As Professor of Experimental Physics at the Cavendish Laboratory in Cambridge University, she studies the microscopic structure of everyday stuff, from plants to plastics. Jim Al-Khalili talks to Athene about her life and her passionate campaign to get more women working in science. Producer: Michelle Martin
Melvyn Bragg and guests discuss the giant molecules that form the basis of all life. Macromolecules, also known as polymers, are long chains of atoms. They form the proteins that make up our bodies, as well as many of the materials of modern life. Man's ability to mimic the structure of macromolecules has led to the invention of plastics such as nylon, paints and adhesives. Most of our clothes are made of macromolecules, and our food is macromolecular. The medical sciences are making increasingly sophisticated use of macromolecules, from growing replacement skin and bone to their increasing use in drug delivery. One of the most famous macromolecules is DNA, an infinitely more complex polymer than man has ever managed to produce. We've only known about macromolecules for just over a century, so what is the story behind them and how might they change our lives in the future?With:Tony RyanPro-Vice Chancellor for the Faculty of Science at the University of SheffieldAthene DonaldProfessor of Experimental Physics at the University of Cambridge and a Fellow of Robinson CollegeCharlotte WilliamsReader in Polymer Chemistry and Catalysis at Imperial College, London Producer: Natalia Fernandez.

Melvyn Bragg and guests discuss mysterious phenomena called Gravitational Waves in contemporary physics. The rather un-poetically named star SN 2006gy is roughly 150 times the size of our sun. Last week it went supernova, creating the brightest stellar explosion ever recorded. But among the vast swathes of dust, gas and visible matter ejected into space, perhaps the most significant consequences were invisible – emanating out from the star like the ripples from a pebble thrown into a pond. They are called Gravitational Waves, predicted by Einstein and much discussed since, their existence has never actually been proved but now scientists may be on the verge of measuring them directly. To do so would give us a whole new way of seeing the cosmos. But what are gravitational waves, why are scientists trying to measure them and, if they succeed, what would a gravitational picture of the universe look like?With Jim Al-Khalili, Professor of Physics at the University of Surrey; Carolin Crawford, Royal Society Research Fellow at the Institute of Astronomy, Cambridge; Sheila Rowan, Professor in Experimental Physics in the Department of Physics and Astronomy at the University of Glasgow

Melvyn Bragg and guests discuss the Higgs Boson particle. One weekend in 1964 the Scottish scientist Peter Higgs was walking in the Cairngorm Mountains. On his return to his laboratory in Edinburgh the following Monday, he declared to his colleagues that he had just experienced his 'one big idea' and now had an answer to the mystery of how matter in the universe got its mass. That big idea took many years of refining, but it has now generated so much international interest and has such an important place in physics that well over one billion pounds is being spent in the hope that he was right. It's the biggest science project on Earth; the quest to find the 'Higgs Boson', a fundamental constituent of nature that - if it does exist - has such a central role in defining the universe that it's also known as the God Particle.What is the Higgs Boson? Why is it so important to scientists and how are they planning to find it?With Jim Al-Khalili, Senior Lecturer in Physics at the University of Surrey; David Wark, Professor of Experimental Physics at Imperial College London and the Rutherford Appleton Laboratory; Professor Roger Cashmore, former Research Director at CERN and now Principal of Brasenose College, Oxford.
