Paul Erdős (1913 – 1996) is one of the most celebrated mathematicians of the 20th century. During his long career, he made a number of impressive advances in our understanding of maths and developed whole new fields in the subject. He was born into a Jewish family in Hungary just before the outbreak of World War I, and his life was shaped by the rise of fascism in Europe, anti-Semitism and the Cold War. His reputation for mathematical problem solving is unrivalled and he was extraordinarily prolific. He produced more than 1,500 papers and collaborated with around 500 other academics. He also had an unconventional lifestyle. Instead of having a long-term post at one university, he spent much of his life travelling around visiting other mathematicians, often staying for just a few days. With Colva Roney-Dougal Professor of Pure Mathematics at the University of St Andrews Timothy Gowers Professor of Mathematics at the College de France in Paris and Fellow of Trinity College, Cambridge and Andrew Treglown Associate Professor in Mathematics at the University of Birmingham The image above shows a graph occurring in Ramsey Theory. It was created by Dr Katherine Staden, lecturer in the School of Mathematics at the Open University.

Vašek Chvátal was born in Prague and received his undergraduate degree in mathematics in the same city. He left Czechoslovakia in August 1968, three days after its Soviet-led invasion. Having earned his Ph.D. in mathematics from the University of Waterloo in the fall of 1970, he taught mathematics, computer science, and operations research at McGill, Stanford, Université de Montréal, and Rutgers. From 2004 till his retirement in 2014, he held a Canada Research Chair, first in Combinatorial Optimization and then in Discrete Mathematics, at Concordia University in Montreal. His research agenda has ranged from graph theory and combinatorics to linear programming and cutting planes to analysis of algorithms to the traveling salesman problem. In 2015, he shared the John von Neumann Theory Prize 'for seminal and profound contributions to the theoretical foundations of optimization' with Jean Bernard Lasserre. His most recent book, "The Discrete Mathematical Charms of Paul Erdős", was published last August by Cambridge University Press.

Dr. Fan Chung Graham is the Paul Erdös Professor in Combinatorics at the University of California, San Diego, California. Dr. Chung Graham's research interests include spectral graph theory, extremal graph theory, graph labeling, graph decompositions, random graphs, graph algorithms, parallel structures, and various applications of graph theory in Internet computing, communication networks, software reliability, chemistry, and engineering. In a conversation with students from Simon Fraser University, Amritha Raj Kizhakkeputhukulathil Ramanan, Anmol Anmol Singh, and Brian Krammer, Dr. Chung Graham talks about how she as a graduate student worked on improving the lower bound of R(3,3,3,3), tells about the benefits that art brings to her life, and shares some of her memories about her husband Ron Graham.

We will discuss how other safety science researchers have designed theories that use Rasmussen's concepts, the major takeaways from Rasmussen's article, and how safety professionals can use these theories to analyze and improve systems in their own organizations today. Discussion Points:Rasmussen's history of influence, and the parallels to (Paul) Erdős numbers in research paper publishingHow Rasmussen is the “grandfather” of safety scienceRasmussen's impact across disciplines and organizational categories through the yearsThe basics of this paperWhy risk management models must never be staticHow other theorists and scientists take Rasmussen's concepts and translate them into their own models and diagramsThe paper's summary of the evolution of theoretical approaches up until ‘now' (1997)Why accident models must use a holistic approach including technology AND peopleHow organizations are always going to have pressures of resources vs. required resultsEmployees vs. Management– both push for results with minimal acceptable effort, creating accident riskRasmussen identified we need different models that reflect the real worldTakeaways for our listeners from Rasmussen's work Quotes:“That's the forever challenge in safety, is people have great ideas, but what do you do with them?  Eventually, you've got to turn it into a method.” - Drew Rae“These accidental events are shaped by the activity of people.  Safety, therefore, depends on the control of people's work processes.” - David Provan“There's always going to be this natural migration of activity towards the boundaries of acceptable performance.” - David Provan“This is like the most honest look at work I think I've seen in any safety paper.” - Drew Rae“If you're a safety professional, just how much time are you spending understanding all of these ins and outs and nuances of work, and people's experience of work? …You actually need to find out from the insiders inside the system. ” - David Provan“‘You can't just keep swatting at mosquitos, you actually have to drain the swamp.'

John Von Neumann was born in Hungary at the tail end of the Astro-Hungarian Empire. The family was made a part of the nobility and as a young prodigy in Budapest, He learned languages and by 8 years old was doing calculus. By 17 he was writing papers on polynomials. He wrote his dissertation in 1925 he added to set theory with the axiom of foundation and the notion of class, or properties shared by members of a set. He worked on the minimax theorem in 1928, the proof of which established zero-sum games and started another discipline within math, game theory. By 1929 he published the axiom system that led to Von Neumann–Bernays–Gödel set theory. And by 1932 he'd developed foundational work on ergodic theory which would evolve into a branch of math that looks at the states of dynamical systems, where functions can describe a points time dependence in space. And so he of course penned a book on quantum mechanics the same year. Did we mention he was smart and given the way his brain worked it made sense that he would eventually gravitate into computing. He went to the best schools with other brilliant scholars who would go on to be called the Martians. They were all researching new areas that required more and more computing - then still done by hand or a combination of hand and mechanical calculators. The Martians included De Hevesy, who won a Nobel prize for Chemistry. Von Kármán got the National Medal of Science and a Franklin Award. Polanyl developed the theory of knowledge and the philosophy of science. Paul Erdős was a brilliant mathematician who published over 1,500 articles. Edward Teller is known as the father of the hydrogen bomb, working on nuclear energy throughout his life and lobbying for the Strategic Defense Initiative, or Star Wars. Dennis Gabor wrote Inventing the Future and won a Nobel Prize in Physics. Eugene Wigner also took home a Nobel Prize in Physics and a National Medal of Science. Leo Szilard took home an Albert Einstein award for his work on nuclear chain reactions and joined in the Manhattan Project as a patent holder for a nuclear reactor. Physicists and brilliant scientists. And here's a key component to the explosion in science following World War II: many of them fled to the United States and other western powers because they were Jewish, to get away from the Nazis, or to avoid communists controlling science. And then there was Harsanyl, Halmos, Goldmark, Franz Alexander, Orowan, and John Kemeny who gave us BASIC. They all contributed to the world we live in today - but von Neumann sometimes hid how smart he was, preferring to not show just how much arithmetic computed through his head. He was married twice and loved fast cars, fine food, bad jokes, and was an engaging and enigmatic figure. He studied measure theory and broke dimension theory into algebraic operators. He studied topological groups, operator algebra, spectral theory, functional analysis and abstract Hilbert space. Geometry and Lattice theory. As with other great thinkers, some of his work has stood the test of time and some has had gaps filled with other theories. And then came the Manhattan project. Here, he helped develop explosive lenses - a key component to the nuclear bomb. Along the way he worked on economics and fluid mechanics. And of course, he theorized and worked out the engineering principals for really big explosions. He was a commissioner of the Atomic Energy Commission and at the height of the Cold War after working out game theory, developed the concept of mutually assured destruction - giving the world hydrogen bombs and ICBMs and reducing the missile gap. Hard to imagine but at the times the Soviets actually had a technical lead over the US, which was proven true when they launched Sputnik. As with the other Martians, he fought Communism and Fasciscm until his death - which won him a Medal of Freedom from then president Eisenhower. His friend Stanislaw Ulam developed the modern Markov Chain Monte Carlo method and Von Neumann got involved in computing to work out those calculations. This combined with where his research lay landed him as an early power user of ENIAC. He actually heard about the machine at a station while waiting for a train. He'd just gotten home from England and while we will never know if he knew of the work Turing was doing on Colossus at Bletchley Park, we do know that he offered Turing a job at the Institute for Advanced Study that he was running in Princeton before World War II and had read Turing's papers, including “On Computable Numbers” and understood the basic concepts of stored programs - and breaking down the logic into zeros and ones. He discussed using ENIAC to compute over 333 calculations per second. He could do a lot in his head, but he wasn't that good of a computer. His input was taken and when Eckert and Mauchly went from ENIAC to EDVAC, or the Electronic Discrete Variable Calculator, the findings were published in a paper called “First Draft of a Report on the EDVAC” - a foundational paper in computing for a number of reasons. One is that Mauchly and Eckert had an entrepreneurial spirit and felt that not only should their names have been on the paper but that it was probably premature and so they quickly filed a patent in 1945, even though some of what they told him that went into the paper helped to invalidate the patent later. They considered these trade secrets and didn't share in von Neumann's idea that information must be set free. In the paper lies an important contribution, Von Neumann broke down the parts of a modern computer. He set the information for how these would work free. He broke down the logical blocks of how a computer works into the modern era. How once we strip away the electromechanical computers that a fully digital machine works. Inputs go into a Central Processing Unit, which has an instruction register, a clock to keep operations and data flow in sync, and a counter - it does the math. It then uses quick-access memory, which we'd call Random Access Memory, or RAM today, to make processing data instructions faster. And it would use long-term memory for operations that didn't need to be as highly available to the CPU. This should sound like a pretty familiar way to architect devices at this point. The result would be sent to an output device. Think of a modern Swift app for an iPhone - the whole of what the computer did could be moved into a single wafer once humanity worked out how first transistors and then multiple transistors on a single chip worked. Yet another outcome of the paper was to inspire Turing and others to work on computers after the war. Turing named his ACE or Automatic Computing Engine out of respect to Charles Babbage. That led to the addition of storage to computers. After all, punched tape was used for Colossus during the war and and punched cards and tape had been around for awhile. It's ironic that we think of memory as ephemeral data storage and storage as more long-term storage. But that's likely more to do with the order these scientific papers came out than anything - and homage to the impact each had. He'd write The Computer and the Brain, Mathematical Foundations of Quantum Mechanics, The Theory of Games and Economic Behavior, Continuous Geometry, and other books. He also studied DNA and cognition and weather systems, inferring we could predict the results of climate change and possibly even turn back global warming - which by 1950 when he was working on it was already acknowledged by scientists. As with many of the early researchers in nuclear physics, he died of cancer - invoking Pascal's wager on his deathbed. He died in 1957 - just a few years too early to get a Nobel Prize in one of any number of fields. One of my favorite aspects of Von Neumann was that he was a lifelong lover of history. He was a hacker - bouncing around between subjects. And he believed in human freedom. So much so that this wealthy and charismatic pseudo-aristocrat would dedicate his life to the study of knowledge and public service. So thank you for the Von Neumann Architecture and breaking computing down into ways that it couldn't be wholesale patented too early to gain wide adoption. And thank you for helping keep the mutually assured destruction from happening and for inspiring generations of scientists in so many fields. I'm stoked to be alive and not some pile of nuclear dust. And to be gainfully employed in computing. He had a considerable impact in both.

On this episode, we talk about the following: On Almedalsveckan (https://almedalsveckan.info/), dissent and purpose of education being gaining consent. Closed borders. On making decisions and sticking with them. WHY do we struggle with making decisions vs HOW do we struggle with making them? Playing cards. Slow and fast thinking. "You cannot tell the quality of a decision from the outcome. [..] You can make the best decision you can, based on what you know, but the success of your decision will be heavily influenced by (a) relevant information you may lack and (b) luck or randomness." — Howard Marks, Oaktree Capital On winning as the basic premise which we make our decisions off of (winner/loser). Allowed to think, and provide your expertise. What decisions are worth your energy? Process-oriented model and patterned behaviours. Theory U.

Borrelpraat is terug! Het nieuwe seizoen start lekker chaotisch en lang, met feitjes over een Titanic replica, psychologische spelletjes met kinderen, de Dag Dat Disco Doodging en een Hongaarse machine die caffeine omzet in wiskundige theorieën.

Paul ErdÅ‘s, the famously eccentric, peripatetic and prolific 20th-century mathematician, was fond of the idea that God has a celestial volume containing the perfect proof of every mathematical theorem. “This one is from The Book,” he would declare when he wanted to bestow his highest praise on a beautiful proof. Never mind that ErdÅ‘s doubted God's very existence.

A solid routine fosters a well-worn groove for one’s mental energies and helps stave off the tyranny of moods. In this episode of Made You Think, Neil and I discuss​ Daily Rituals by Mason Currey. In this book, Currey edits together first-hand accounts from different artists and creative thinkers of how they went about their everyday lives. “I write when the spirit moves me,”  said, “and the spirit moves me every day.” – Faulkner. We cover a wide range of topics, including: The problem with lifestyle gurus. Whether drugs enhance genius. Coffee’s role in causing the Renaissance. How people in far-off countries let each other know they were alive before the internet. Beethoven’s perfect cup of Joe. Why you should pin notes to your clothes' Night Owls vs. Early Birds - who gets more worms. Hacks to become an morning person. And much more. Please enjoy, and be sure to grab a copy of Daily Rituals: How Artists Work by Mason Currey! If you enjoyed this episode, be sure to check out our episode on 12 Rules for Life by Jordan B.

Broad interpretation of artists, anyone who does creative or critical thinking work. 01:24 – There’s a surprising amount of drug-use in this book, lots of alcohol, and not sleeping. On the one hand this seemed undisciplined, but on the other these people did have very regular schedules. There was discipline to keep these activities in a well-worn groove. 01:53 – A hangover can make it easier to write – your brain can be more focused. In some ways it’s like the opposite of being caffeinated. 03:10 – The book has an interesting layout, there’s no attempt at narrative, each chapter is about a new person’s routine. 03:54 – Taleb keeps no routine, he doesn’t even use a calendar. 04:00 – Small gripe with books like this as these are idealized and narrativized versions of these rituals. None of them get drunk and yell at people on Twitter. Wouldn’t be surprised if they’re only true 20-50% of the time. 04:55 – Problem with a lot of the lifestyle guru type people. They don’t do all of that stuff everyday. Except Jocko, he’s never overslept in the last 15 years. His morning routine seems to be the same wherever he is. 06:02 – Maintaining a normal schedule when you travel across time zones helps you adapt way faster. The minute you go back to your hotel you’ll crash, it’s game over! Jet lag is a strange tiredness, especially if you drink coffee, like you’re wired and drunk at the same time. 08:00 – Questioning whether you can save up a store of sleep for a rainy day. Apparently you can’t front load it, but when you get into debt you need to pay it back! 08:46 – Types of polyphasic sleep. Buckminster Fuller developed dymaxion sleep, he did it for two years and he’s the only one who’s ever been able to do it. 5-10% of the population legitimately need less sleep. Everyone else thinks they’re in that group but they’re not. 09:05 – When they tried one study on polyphasic sleep the subject just crashed and they could not wake him up. 11:43 – Is it quote or quotation? Don’t want to anger the grammar people! 11:55 – Download all of our episodes to find out whether one of our team is part of the alt-right. 12:58 – Auden was popping Benzedrine all the time. He regarded it as a “labor saving device,” a daily multivitamin. In the mental kitchen alongside alcohol, coffee and tobacco. 13:40 – Were these people great producers because of these habits or despite them? Question of whether the live-fast, die-young lifestyle enhances genius. 16:22 – Personal experiences and use of some drugs. Coffee for work and productivity, micro-dosing LSD for the same. Marijuana for an after wine session. Fear of getting hooked with tobacco vs alcohol. 18:34 – Ritalin/Aterol for effortless full-speed ahead concentration. 20:12 – Doctors overprescribe Aterol – 90% of people taking it don’t need it. It’s very hard to quit, people get frustrated at never hitting the same level of quality. In some ways similar to steroids. 22:26 – The Renaissance happened when people stopped drinking beer all day and switched to coffee. 22:36 – Drinking habits around the world. Beer used to be brewed as water wasn’t safe to drink. They would steep the same grains up to four times. In Asia they would drink tea all day, which is probably why they were historically more productive than Europe. 24:55 – In sushi bars in Tokyo they have a tap of green tea. In Germany they give you beer, Americans drink water and now they’re more productive because they’re hydrated. 25:53 – Tangent – Most people who are in America now, their ancestors were the risk-takers. The people who took the initiative to leave behind everything they knew. So culturally this is ingrained. 26:59 – People used booked calls to let family on the other side of the world know they were alive before Skype. 27:40 – The history of pokes on Facebook – they would let a non-friend see your profile for a few days without actually becoming your friend. 29:10 – A significant number of people featured in the book seemed to have OCD, they were trying to control chaos. Beethoven’s coffee had to have 60 beans a cup. Kant had an extremely orderly schedule. The clock tower in town stayed on time less passionately than Kant. 32:00 – Everyone has odd habits, especially artists who spend a lot of time in their heads. 32:21 – The general impression of Benjamin Franklin is “early to bed, early to rise” but he seemed to set his 13 virtues up as goals rather than things he’d achieved. Comparing Ben Franklin to Tim Ferriss. People disapprove of others not following their own advice to the letter. 35:53 – Controversy when one updates his opinions. 36:16 – It’s surprising how few hours people worked – the bulk of the creative work was 5-6 hours a day, max. Darwin was famous for having two 3 hour work blocks. It’s hard to do creative work for longer. But good for mental energy. 38:00 – Tangent. It’s hard to be spontaneous in New York. Phone calls are scheduled a week in advance.  Time management tips: set regular stand-ups, only book meetings at certain times. Color-code your calendar. 40:30 – Work environments are moving towards being more results orientated, moving away from people just sitting at their desks doing nothing. A relic of the production line. Schedule Tetris in large corporations. 43:26 – Hack. Schedule hour meetings for 40 minutes, or half hour meetings for 20 minutes. It forces people to condense. 44:58 – Data should make it easier for people to get paid based on productivity rather than time. For consulting jobs, it doesn’t make sense to charge based on time. Historically, time was the best way of measuring output and so this made sense. 47:43 – Education is also stuck in this time loop since it was originally influenced by factory organization. Most interesting ideas that end up leading somewhere come from play, from free time. 49:21 – After unsuccessfully trying for ten years in New York, Henry Miller had given up writing, when he finally wrote a novel in Paris it was published without editing, there’s sentences that just stop mid-way. Seeing from outside, it seems these creatives are able to follow a routine without anyone forcing them. 51:44 – Jordan Peterson says there’s no such thing as writer’s block. If you’re stuck it’s because you have run out of things to say, you need to unblock yourself. 53:10 – Sleep and wake up at the same time every day, even on weekends, may make you feel much more energized. Sleeping in on the weekend it’s almost like changing time zones every five days. 56:41 – Giveaways are coming, sign up for the email list. 57:03 – To remember to do important things pin a piece of paper on a different piece of your clothing, a form of mnemonics. 58:15 – When you first wake up, that’s a different person. You have to find ways of tricking him into not hitting snooze. Routines and replacement can help you get past undesirable behavior. 59:04 – Sponsor time. Mushroom elixir from Four Sigmatic and bone broth from Kettle & Fire along with Perfecto Keto collagen. Use them to replace alcohol in the evening! 1:01:38 – Despite living in climate controlled environments, we still feel like it’s cold outside when it’s winter, even though it’s the same temperature where we are. 1:03:30 – Some people’s capacity for alcohol is so far beyond the average. If you’re regimented and disciplined you could physically drink a bottle of spirits a day. 1:07:15 – Sugar is like a mild form of cocaine. It’s a stimulant followed by a crash. Hormetic stressors are only “natural”. 1:09:20 – Psycho-active drugs don’t make your brain do things it can’t do, they mimic neural pathways. Maybe adaptation is down-regulating the amount of neurochemicals being released in response to the trigger. If you know, write in! 1:11:36 – Morning Working vs Night-time working theme. More of the creators were geared towards mornings but it wasn’t across the board. Evolutionarily, it doesn’t make sense for humans to want to work at night. 1:14:20 – Waking up hack. Trick yourself into getting up by telling yourself you can go back to bed in 30 minutes if you’re still tired. 1:14:45 – Wrap-up and sponsor time. Perfecto Keto is perfect for all your ketogenic diet needs. Exogenous coffee-flavored ketones. Their matcha MCT oil powder is highly recommended for focusing. You can use the MCT oil with a Four Sigmatic mushroom coffee or your hot chocolate, all 15% OFF through our sponsored link or use the coupon code mentioned. Kettle & Fire will give you 20% OFF on their delicious bone broths –beef recommended for cooking, and chicken for a good, hot wintery drink– and free shipping!

In 1770, Hungarian engineer Wolfgang von Kempelen unveiled a miracle: a mechanical man who could play chess against human challengers. In this week's episode of the Futility Closet podcast we'll meet Kempelen's Mechanical Turk, which mystified audiences in Europe and the United States for more than 60 years. We'll also sit down with Paul Erdős and puzzle over a useful amateur. Intro: Lewis Carroll sent a birthday wish list to child friend Jessie Sinclair in 1878.

Exploring the beauty of maths, we may just find that faith and proof are not mutually exclusive. --- "An equation for me has no meaning unless it expresses a thought of God." - Srinivasa Ramanujan. Ramanujan was a self-taught mathematical genius from India, who moved to Cambridge University in 1914 to work with the eminent mathematician, G. H. Hardy. His story, as told in the movie The Man Who Knew Infinity, is not only one of a brilliant mind capable of remarkable work, but of an unlikely friendship between a devout Hindu, and an atheist who was a stickler for proofs. "Your theorem is wrong," Hardy tells Ramanujan in the movie, "this is why we cannot publish anymore until you finally trust me on this business of proofs." Once described as "the most romantic figure in recent mathematical history", Ramanujan's life also speaks to the idea of finding beauty in maths - and this is what we explore in this episode of Life & Faith. You'll hear from a leading Australian mathematician about her response to the film, and her sense of the relationship between divine reality and mathematical practice. Then, Oxford mathematics professor John Lennox shares his thoughts about the beauty of the world of numbers and patterns. We wrap up the episode with a poem written and read by former Archbishop of Canterbury, Rowan Williams - you won't want to miss it. "Why are numbers beautiful? It's like asking why is Beethoven's Ninth Symphony beautiful. If you don't see why, someone can't tell you. I know numbers are beautiful. If they aren't beautiful, nothing is." - Paul Erdős --- This episode was first broadcast on 30 June 2016.

Mathematician Paul Erdős had no home, no job, and no hobbies. Instead, for 60 years he wandered the world, staying with each of hundreds of collaborators just long enough to finish a project, and then moving on. In this week's episode of the Futility Closet podcast we'll meet the "magician of Budapest," whose restless brilliance made him the most prolific mathematician of the 20th century. We'll also ponder Japanese cannibalism in World War II and puzzle over a senseless stabbing. Intro: Elbert Hubbard published 12 blank pages in 1905. A duck spent 18 months in the U.S. 2nd Marine Division in 1943. Sources for our feature on Paul Erdős: Paul Hoffman, The Man Who Loved Only Numbers, 1999. The magisterial biography of Erdős.

In the sixth Advent Podcast, Robin Ince talks to Dave Gorman about the mathematician Paul Erdős, and how, where all actors have a "Bacon Number" to denote their degrees of separation from Kevin Bacon, all mathematicians have an Erdős Number. He would also like a Soda Stream for Christmas. Recorded in 2008. Music by Andrea Rocca.
