The Open Gate of Mathematics: From the Alhambra to Escher
56:25
In 1922, a 24-year-old artist named M.C. Escher visited the Alhambra, a 13th-century Moorish fortress and palace in Granada, Spain. The stunning Islamic design and geometric patterns overwhelmed the young artist, who began a 50-year obsession with dividing the plane. Today, Escher’s name is synonymous with tessellations, symmetry, and impossible shapes. His art’s mathematical structure has affected fields as far-reaching as combinatorics, graph theory, non-Euclidean geometry, and crystallography. This seminar focuses on Escher’s exploration of the two-dimensional plane and his link to the Moorish artisans of the past, begging the question: Were these artists doing math? Presented by Jeff Powers.

Math Hippies - The Pythagoreans by Carolyn Evans
34:47
Once upon a time, in an Italian seaport far far away, a strange cult of young aristocrats arose under the leadership of the mystical and mysterious Pythagoras...
The Pythagoreans were a philosophical society with some pretty radical world views and hippie-esque habits. They believed “that the elevation of the soul to union with the divine occurs by means of mathematics”, and that being strict vegetarians, abstinent from alcohol, and keeping no personal belongings would help them reach this goal.
This seminar will cover some of the philosophical foundations, famous legends, mathematical discoveries, and longstanding impacts that this group accomplished thousands of years ago.

Biodiversity scientists as honest brokers or advocates? | Jonathan Chase | TEDxUniHalle
17:18
What is meant by biodiversity and why is it so important for our lives? This is the question Jonathan M. Chase is dealing with every day. He is a professor of biodiversity synthesis at the German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig and Center for Computer Science of Martin-Luther-University Halle-Wittenberg. At TEDxUniHalle 2017 he overviews the concept of biodiversity and its influence on ecosystem and human welfare, as well as the problems (and solutions) of how to quantify it to develop more meaningful comparisons.
Biodiversity is a concept that has been connected to ecosystem services and functions in recent years, as well as to human health and welfare. Biodiversity is also strongly influenced by natural processes that occur over millions of years across the planet and by human activities that have occurred over the past few hundred years. Despite the clear importance of biodiversity for understanding the natural processes of life and for its direct influence on humans, our tools on exactly how to quantify what biodiversity is and how it varies to influence ecosystems remain rudimentary. The question is: Are biodiversity scientists honest brokers or advocates?
Jonathan M. Chase is a professor of biodiversity synthesis at the German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig and Center for Computer Science of Martin-Luther-University Halle-Wittenberg.
He was born in the U.S. in 1970, studied at University of Michigan and Utah State and completed his Ph.D. at University of Chicago in 1998. After several positions in academia and research as well as numerous awards such as the American Society of Naturalists ‘Young Investigator Prize’ (1999) and the Saint Louis Academy of Sciences ‘Innovator Award’ (2009), Jonathan Chase, together with his wife and two children, moved to Germany in 2014. His current research activities focus on biodiversity and community ecology.

Inklings on Adventurous & Exotic Lives by Way of Narrative Practice | Kevan Walker | TEDxFairbanks
20:56
In this talk, Kevan discusses how the clinical field of Narrative Practice has made forays into community work from its therapeutic beginnings. He also muses on the inklings he’s gotten of what possibilities play at the leading edges of our individual & collective lives, the hats we wear, relating these through bewitching stories told at the edge.
Kevan is a Licensed Marriage & Family Therapist, though prefers the title “Relentless Collector of Magical Moments” (borrowed from acclaimed Photographer Stephen Wilkes) due to the exotic lives he’s uncovered whilst consulting the human beingness of others. Through his Narrative Therapy practice in Fairbanks, Alaska, Kevan enters conversations from a collaborative, appreciative, & curious position to then with his consultants “spit in the soup” of taken-for- granted societal norms, discover & illuminate the adventurous & exotic stories that have been edited out of their lives. He’s been most interested in engaging in discussions around: masculinity, white privilege, medical dialogues, colonization, Dignified Defiance, Latter-Day Saints, & whatever else piques his & other’s curiosity.

Can You Catch Yourself? | Christy Vincent | TEDxUCO
12:39
We all have ways of being in the world. Sometimes those work for us, but sometimes, they work to our detriment by keeping us from new insights and by allowing us to repeat unwanted behavior in our relationships. Dr. Christy Vincent, a business and professional coach, demonstrates how we can catch ourselves before we become our own stumbling block.
Dr. Christy Vincent is a professor in the Mass Communication Department at the University of Central Oklahoma, where she teaches organizational and strategic communication courses. Her research interests include conflict management, mediation, change management, executive coaching, and training and development. Her interest in conflict management led her to the Straus Institute for Dispute Resolution at the Pepperdine University School of Law, where she earned a Certificate in Alternative Dispute Resolution (ADR).
Christy is a communication specialist. Using her years of experience in organizational effectiveness and conflict management, she coaches individuals to increase their leadership effectiveness. While she has coached individuals in all roles, one of her specialties is working with young directors who are being groomed for higher-level positions.

Kurt Godel: The Worlds Most Incredible Mind
15:00
Kurt Godel: The World's Most Incredible Mind.
Either mathematics is too big for the human mind or the human mind is more than a machine ~ Godel
Kurt Godel (1931) proved two important things about any axiomatic system rich enough to include all of number theory.
1) You'll never be able to prove every true result..... you'll never be able to prove every result that is true in your system.
2) Godel also proved that one of the results that you can never prove is the result that says that the system is consistent. More precisely: You cannot prove the consistency of any mathematical system rich enough to include the known theory of numbers.
Hence, any consistent mathematical system that is rich enough to include number theory is inherently incomplete.
Second, one of the propositions whose truth or falsity cannot be proved within the system is precisely the proposition that states that the system is consistent.
What Godel's proof means, then, is that we can't prove that arithmetic—let alone any more-complicated system—is consistent.
For 2000 years, mathematics has been the model—the subject—that convinces us that certainty is possible. Yet Now there's no certainty anywhere—not even in mathematics.
More...
Goedel's Ontological Proof.
For those interested in a discussion of Goedel's reasoning for God, then I suggest starting with this heavily annotated work, which I recently stumbled upon.
scribd.com/doc/95364925/Goedel-s-God-Proof-Annotated-Version
It's not that God is subject to the Freedom Proof or the Doubt Proof.
According to Gödel, He's not. But we have to be, or else we are not free. So
our truth game with God turns into something like Feynman had described.
Feynman's Gods, every time physicists think they have the rules of the game
figured out, throw in a new wrinkle. They let people like Feynman make
progress, but if the Feynmans of the world learn too much, physics will stop
being the joy and challenge that it is. The Gods don't let that happen.
Gödel's God has to be very careful about how he lets our universe unfold.
If the world becomes totally controllable and comprehensible, we'll be God.
God does not object to that. In fact, according to Gödel, that is our destiny.
But it is also the end of us as free human beings. And human freedom is an
essential part of the beauty of God's universe.

A Tribute to Euler - William Dunham

A Tribute to Euler
William Dunham
Truman Koehler Professor of Mathematics, Muhlenberg College
Tuesday, October 14, 2008, at 6:00 PM
Harvard University Science Center, Hall D
The fall 2008 Clay Public Lecture will be held at Harvard on October 14, in association with the Harvard Mathematics Department. Known for his writings on the history of mathematics, Professor William Dunham will examine the genius of one of the world's most prolific mathematicians in his talk A Tribute to Euler in Hall D of the Harvard Science Center at 6 pm.
Among history's greatest mathematicians is Leonhard Euler (1707-1783), the Swiss genius who produced an astonishing 25,000 pages of pure and applied mathematics of the very highest quality.
In this talk, we sketch Euler's life and describe a few of his contributions to number theory, algebra, and other branches of mathematics. Then we examine a particular Eulerian theorem: his simple but beautiful proof that there are as many ways to decompose a whole number as the sum of distinct summands as there are ways to decompose it as the sum of (not necessarily distinct) odd summands.
Condorcet, in his Eulogy to Euler, wrote that All mathematicians now alive are his disciples. It should be clear to those who attend the Clay Public Lecture that these words are as true today as when they were first set down, over two centuries ago.
William Dunham, who received his B.S. (1969) from the University of Pittsburgh and his M.S. (1970) and Ph.D. (1974) from Ohio State, is the Truman Koehler Professor of Mathematics at Muhlenberg College. In the fall term of 2008 he is visiting at Harvard University and teaching a course on the work of Leonhard Euler.
Over the years, he has directed NEH seminars on the history of mathematics and has spoken on historical topics at dozens of U.S. colleges and universities, as well as at the Smithsonian Institution, the Swiss Embassy in Washington, and on NPR's Talk of the Nation: Science Friday.
In the 1990s, Dunham wrote three books on mathematics and its history: Journey Through Genuis: The Great Theorems of Mathematics (1990), The Mathematical Universe (1994), and Euler: The Master of Us All (1999). In the present millennium, he has written The Calculus Gallery: Masterpieces from Newton to Lebesgue (2005) and edited The Genius of Euler: Reflections on His Life and Work (2007). His expository writing has been recognized by the Mathematical Association of America with the George Pólya Award in 1992, the Trevor Evans Award in 1997, the Lester R. Ford Award in 2006, and the Beckenbach Prize in 2008. The Association of American Publishers designated The Mathematical Universe as the Best Mathematics Book of 1994.
Our thanks to the Harvard Mathematics Department for hosting this event.

Mysteries of the Mathematical Universe
1:16:48
Mathematical mysteries have challenged humanity’s most powerful thinkers and inspired passionate, lifelong obsessions in search of answers. From the strangeness of prime numbers and the nature of infinity, to the turbulent flow of fluids and the geometry of hyperspace, mathematics is our most potent tool for revealing immutable truths. The event was a vibrant tour to the boundaries of the mathematical universe, and explore the deep puzzles that have been solved, the masterminds who powered the breakthroughs, and the towering challenges that have shaken the confidence of some of today’s most accomplished mathematicians—even as they enlist new ways to pursue mathematical truths.

MathHistory1a: Pythagoras theorem
48:55
Pythagoras' theorem is both the oldest and the most important non-trivial theorem in mathematics.
This is the first part of the first lecture of a course on the History of Mathematics, by N J Wildberger, the discoverer of Rational Trigonometry. We will follow John Stillwell's text Mathematics and its History (Springer, 3rd ed). Generally the emphasis will be on mathematical ideas and results, but largely without proofs, with a main eye on the historical flow of ideas. A few historical tidbits will be thrown in too...
In this first lecture (with two parts) we first give a very rough outline of world history from a mathematical point of view, position the work of the ancient Greeks as following from Egyptian and Babylonian influences, and introduce the most important theorem in all of mathematics: Pythagoras' theorem.
Two interesting related issues are the irrationality of the 'square root of two' (the Greeks saw this as a segment, or perhaps more precisely as the proportion or ratio between two segments, not as a number), and Pythagorean triples, which go back to the Babylonians. These are closely related to the important rational parametrization of a circle, essentially discovered by Euclid and Diophantus. This is a valuable and under-appreciated insight which high school students ought to explicitly see.
In fact young people learning mathematics should really see more of the history of the subject! The Greeks thought of mathematics differently than we do today, and all students can benefit from a closer appreciation of the difficulties which they saw, but which we today largely ignore.
This series has now been extended a few times--with more than 35 videos on the History of Mathematics.

To err is to human, and I human a lot. I always try my best to be as correct as possible, but unfortunately I make mistakes. This is the errata where I correct my silly mistakes. My goal is to one day do a video with no errors!
1. The number one is not a prime number. The definition of a prime number is a number can be divided evenly only by 1, or itself. And it must be a whole number GREATER than 1. (This last bit is the bit I forgot).
2. In the trigonometry section I drew cos(theta) = opposite / adjacent. This is the kind of thing you learn in high school and guess what. I got it wrong! Dummy. It should be cos(theta) = adjacent / hypotenuse.
3. My drawing of dice is slightly wrong. Most dice have their opposite sides adding up to 7, so when I drew 3 and 4 next to each other that is incorrect.

Leonard Susskind
June 26, 2013
Anyone can see that the past is different from the future. Anyone, that is, but theoretical physicists, whose equations do not seem to distinguish the past from the future. How, then, do physicists understand the arrow of time — the fact that the past and future are so different? Leonard Susskind will discuss the paradox of time's arrow and how physicists and cosmologists view it today.
The Riemann Hypothesis: How to make $1 Million Without Getting Out of Bed
1:5:41
Mathematics is patterns and logic, imagination and rigor. It is a way of seeing and a way of thinking. Math Mornings is a series of public lectures aimed at bringing the joy and variety of mathematics to students and their families. Speakers from Yale and elsewhere will talk about aspects of mathematics that they find fascinating or useful. The talks will usually be accessible to students from 7th grade and up, although occasionally some familiarity with high-school subjects will be helpful.
Math Mornings lectures will occur on three Sundays each semester at Yale University. The third lecture for the series was given by Yale Mathematics Professor Alex Kontorovich on December 2, 2012 who spoke about The Riemann Hypothesis: How to make $1 Million Without Getting Out of Bed.
Please see yale.edu/scienceoutreach for further information about Math Mornings and for a list of other free Yale STEM outreach programming and events.
A Brilliant Madness: A Mathematical Genius Descent into Madness
55:05
A Brilliant Madness is the story of a mathematical genius whose career was cut short by a descent into madness. At the age of 30, John Nash, a stunningly original and famously eccentric MIT mathematician, suddenly began claiming that aliens were communicating with him and that he was a special messenger.
Diagnosed with paranoid schizophrenia, Nash spent the next three decades in and out of mental hospitals, all but forgotten. During that time, a proof he had written at the age of 20 became a foundation of modern economic theory. In 1994, as Nash began to show signs of emerging from his delusions, he was awarded a Nobel Prize in Economics. The program features interviews with John Nash, his wife Alicia, his friends and colleagues, and experts in game theory and mental illness.
Go beyond the Oscar-winning drama A Beautiful Mind and learn more about the life of troubled mathematician and Nobel Prize-winner John Nash and his struggle with mental illness in this PBS American Experience documentary. Exclusive interviews with Nash and wife Alicia are included.
James Clerk Maxwell: The Greatest Victorian Mathematical Physicists - Professor Raymond Flood
52:32
James Clerk Maxwell (1831-1879) was one of the most important mathematical physicists of all time, after only Newton and Einstein. Within a relatively short lifetime he made enormous contributions to science which this lecture will survey. Foremost among these was the formulation of the theory of electromagnetism with light, electricity and magnetism all shown to be manifestations of the electromagnetic field. He also made major contributions to the theory of colour vision and optics, the kinetic theory of gases and thermodynamics, and the understanding of the dynamics and stability of Saturn's rings.
This talk was a part of the conference on '19th Century Mathematical Physics', held jointly by Gresham College and the British Society of the History of Mathematics. The transcript and downloadable versions of all of the lectures are available from the Gresham College website:
Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website. There is currently nearly 1,500 lectures free to access or download from the website.

Mersenne Primes and Perfect Numbers: A Love Story by Dan Garbowitz
41:44
GRCC Adjunct Mathematics Instructor Dan Garbowitz talks on how prime numbers and perfect numbers have fascinated professional and amateur mathematicians for centuries, and much about them remains unknown. This talk will provides glimpse of the beauty and mysterious nature of these numbers and the relationships between them. Perfect numbers were known to the Greeks and have been studied since at least the 3rd century B.C. Marin Mersenne, a 17th century theologian and mathematician, developed a list of prime numbers, all with the same interesting form. Sometime later, Leonard Euler proved a fascinating statement that related the perfect numbers to the Mersenne Primes. During this seminar we will investigate this theorem in particular, and other number theory topics relating perfect numbers and Mersenne Primes.
