    Too much Maths, too little History: The problem of Economics

    1:37:11

    This is a recording of the debate hosted by the LSE Economic History Department, in collaboration with the LSESU Economic History Society and the LSESU Economics Society.





    Speakers:
    Proposition Team - Lord Robert Skidelsky & Dr. Ha-Joon Chang
    Opposition Team - Prof. Steve Pisckhe & Prof. Francesco Caselli
    Chair - Professor James Foreman-Peck

    The LSE is currently the only institution to have a separate EH department. We want to encourage students and academics alike to rethink the methodologies used to explain how our world works.

    Do we use the theoretical and econometrical method to create models with assumptions to distil the complexities of human nature and produce measurable results? Or do we use the historical process of considering all factors to provide a more holistic explanation? More importantly, which method should be adopted to better understand increasingly complex economic phenomena in the future?

    We are striving to provide our students breadth that exceeds their current theoretical studies. Hence, whilst we recognise the importance of economic history in allowing us to become closer to the truth and produce more intricate portrayal of events, the significance of models and mathematics remains to be emphasised.

    Indeed, we wish to have this controversially named debate in order to both highlight the tension between the two disciplines and to produce a more nuanced overview in defence of the future of Economics.

    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.

    2011 Hagey Lecture: Dr. Ian Hacking - How did mathematics become possible?

    1:22:27

    In the 2011 Hagey Lecture, Professor Ian Hacking explores how human beings developed the ability to do math.

    Monday, October 3, 2011 at 8:00pm, Humanities Theatre, Hagey Hall

    Drawing from recent cognitive science, the history of early mathematics, social studies of science, and what has been called the archaeology of mind—how fashioning artifacts has changed the human mind itself—the lecture aims less at building bridges between these different kinds of inquiry, than at highlighting how much we are learning right now, and how little we know.

    Ian Hacking is regarded as a leading scholar in the history and philosophy of science, although his work has touched fields as diverse as statistical inference and the emergence of multiple personality disorder. His contributions have earned many awards, including the Killam Prize for Humanities and an appointment to the Order of Canada.

    Waterloo's premier invitational public lecture series since 1970, the Hagey Lectures are co-sponsored by the Faculty Association and the University of Waterloo.

    The Secret Mathematicians - Professor Marcus du Sautoy

    53:54

    Professor du Sautoy examines the way that Mathematics has overtly and covertly inspired some of the greatest artists. He examines how they might be considered as secret mathematicians:

    From composers to painters, writers to choreographers, the mathematician's palette of shapes, patterns and numbers has proved a powerful inspiration. Artists can be subconsciously drawn to the same structures that fascinate mathematicians as they hunt for interesting new structures to frame their creative process.

    Professor du Sautoy will explore the hidden mathematical ideas that underpin the creative output of well-known artists and reveal that the work of the mathematician is also driven by strong aesthetic values.

    MathHistory20: Group theory

    58:54

    Here we give an introduction to the historical development of group theory, hopefully accessible even to those who have not studied group theory before, showing how in the 19th century the subject evolved from its origins in number theory and algebra to embracing a good part of geometry.

    Actually the historical approach is a very fine way of learning about the subject for the first time.

    We discuss how group theory enters perhaps first with Euler's work on Fermat's little theorem and his generalization of it, involving arithmetic mod n. We mention Gauss' composition of quadratic forms, and then look at permutations, which played an important role in Lagrange's approach to the problem of solving polynomial equations, and was then taken up by Abel and Galois.

    The example of the symmetric group is at the heart of the subject, and so we examine S_3. In the 19th century groups of transformations became to be intimately tied to symmetries of geometries, with the work of Klein and Lie. A nice example that ties together the algebraic and geometric sides of the subject is the symmetry groups of the Platonic solids.

    Hardy, Littlewood, Ramanujan and Cartwright - Professor Raymond Flood

    50:48

    The story of the most productive collaborations in mathematical history:

    The collaboration between G.H. Hardy (1877-1947) and J.E. Littlewood (1885-1977) was the most productive in mathematical history. Dominating the English mathematical scene for the first half of the 20th century, they obtained results of great influence, most notably in analysis and number theory. Into their world came the brilliant and intuitive mathematician, Srinivasa Ramanujan (1887-1920), who left India to work with Hardy until his untimely death at the age of 32.

    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.

    The Unreasonable Effectiveness of Quantum Physics in Modern Mathematics -- Robbert Dijkgraaf

    59:56

    Robbert Dijkgraaf, Perimeter Institute for Theoretical Physics
    March 5th, 2014

    ----
    Mathematics has proven to be unreasonably effective in understanding nature. The fundamental laws of physics can be captured in beautiful formulae. In this lecture I want to argue for the reverse effect: Nature is an important source of inspiration for mathematics, even of the purest kind. In recent years ideas from quantum field theory, elementary particles physics and string theory have completely transformed mathematics, leading to solutions of deep problems, suggesting new invariants in geometry and topology, and, perhaps most importantly, putting modern mathematical ideas in a `natural’ context.

    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:

    GRCC Math Lecture: Hyperbolic Geometry

    48:49

    In this seminar Steven Janke will speak on the historical development and fundamental concepts of Hyperbolic Geometry.

    For more than 2000 years, Euclidean Geometry was considered to be “the” Geometry; there were no others.


    Triangles, Parallels, and Perpendiculars: A Story of Geometry

    One of the basic ideas in geometry is that when you add up all the angles in a triangle you get 180 degrees, but is this always true? Consider the earth and one line being the equator and two other lines being lines of longitude. If we pick two longitudinal lines that are perpendicular then these lines will form a triangle. However, this triangle has 3 right angles which add up to 270 degrees. Surely this must be a mistake, or some special case, or maybe there is something wrong with geometry…or could there possibly be alternative geometries?

    Learn about the history of Hyperbolic Geometry, its creation and its discovery, and attempts to prove Euclid’s Parallel Postulate. Some of the major issues with newer geometries are finding logically consistent models, and we will explore some of the famous models for Hyperbolic Geometry and learn some of the basic constructions possible. We will finish with a qualitative investigation into curvature of a surface and what that means for geometry.

    MathHistory27: Sets, logic and computability

    53:01

    In this video we give a very quick overview of a highly controversial period in the development of modern mathematics: the rise of set theory, logic and computability in the late 19th and early 20th centuries.

    Starting with the pioneering but contentious work of Georg Cantor in creating Set Theory arising from questions in harmonic analysis, we discuss Dedekind's construction of real numbers, ordinals and cardinals, and some of the paradoxes that this new way of thinking led to. We also explain how the Schools of Logicism, Intuitionism and Formalism all tried to steer a path around these paradoxes.

    I should qualify this lecture by stating clearly that in fact I don't really ascribe to any of the theories presented here. My objections will be laid out at length in my MathFoundations series. In this video I am mostly overviewing--rather briefly to be sure!-- the standard thinking, even though I have very little sympathy with it.

    But it is important to understand this historical period, since it impacts so heavily on the mathematics that we currently believe in, teach and apply to the world. We are part of a trajectory of human thought, and not necessarily on the pinnacle or high point of that trajectory--much as we would like to think so! In particular, there is much to be learnt by a study of the issues here that so captured the imagination of the late 19th century and early 20th century mathematical and philosophical thinkers.

    MathHistory9: Calculus

    1:00

    Calculus has its origins in the work of the ancient Greeks, particularly of Eudoxus and Archimedes, who were interested in volume problems, and to a lesser extent in tangents. In the 17th century the subject was widely expanded and developed in an algebraic way using also the coordinate geometry of Descartes. This is one of the most important developments in the history of mathematics.

    Calculus has two branches: the differential and integral calculus. The former arose from the study by Fermat of maxima and minima of functions via horizontal tangents.

    The integral calculus computes areas and volumes beyond the techniques of Archimedes. It was developed independently by Newton and Leibnitz, but others contributed too. Newton's focus was on power series, for which differentiation and integration can be done term by term using a formula of Cavalieri, and which gave remarkable new formulas for pi and the circular functions. He had a dynamic view of the subject, motivated in large part by physics.

    Leibnitz was more interested in closed forms, and introduced the notation which we use today. Both used infinitesimals, in the form of differentials.

    MathHistory12: Non-Euclidean geometry

    50:52

    The development of non-Euclidean geometry is often presented as a high point of 19th century mathematics. The real story is more complicated, tinged with sadness, confusion and orthodoxy, that is reflected even the geometry studied today. The important insights of Gauss, Lobachevsky and Bolyai, along with later work of Beltrami, were the end result of a long and circuitous study of Euclid's parallel postulate. But an honest assessment must reveal that in fact non-Euclidean geometry had been well studied from two thousand years ago, since the geometry of the sphere had been a main concern for all astronomers.

    This lecture gives a somewhat radical and new interpretation of the history, suggesting that there is in fact a much better way of thinking about this subject, as perceived already by Beltrami and Klein, but largely abandoned in the 20th century. This involves a three dimensional linear algebra with an unusual inner product, looked at in a projective fashion. This predates and anticipates the great work of Einstein on relativity and its space-time interpretation by Minkowski.

    For those interested, a fuller account of this improved approach is found in my Universal Hyperbolic Geometry (UnivHypGeom) series of YouTube videos.

    MathHistory16: Differential Geometry

    51:32

    Differential geometry arises from applying calculus and analytic geometry to curves and surfaces. This video begins with a discussion of planar curves and the work of C. Huygens on involutes and evolutes, and the related notions of curvature and osculating circle. We discuss involutes of the catenary (yielding the tractrix), cycloid and parabola. The evolute of the parabola is a semi-cubical parabola. For space curves we describe the tangent line, osculating plane, principle normal and binormal.

    Surfaces were studied by Euler, who investigated curvatures of planar sections and by Gauss, who realized that the product of Euler's two principal curvatures gave a new notion of curvature intrinsic to a surface. Curvature was ultimately extended by Riemann to higher dimensions, and plays today a major role in modern physics, due to the work of Einstein.

    Time travel: separating science fact from science fiction

    1:13:54

    Is time travel possible? Science fiction has monopolised this question for so long, we thought it was time to investigate what real science has to say. In this lecture which will cover fascinating ideas in physics that lead from Einstein's theories of relativity, Jim Al-Khalili will treat us to a look at dimensions, investigate how we can possibly imagine living in curved space-time, and how this curvature can cause a black hole to be punched in space.

    Borrowing from science fiction, Professor Al-Khalili will also explore the more problematic question of time travel into the past and the paradoxes that arise. And finally, investigate how we could go about constructing a time machine!

    Gauss and Germain - Professor Raymond Flood

    54:55

    Two of the greatest mathematicians habe their shared history and correspondence examined:
    Carl Friedrich Gauss (1777-1855) was one of the greatest mathematicians of all time. Possibly his most famous work was his book on number theory, published in 1801. After reading this book, the French mathematicians Sophie Germain (1776-1831) began corresponding with Gauss about Fermat's last theorem, using a male pseudonym.
    Subsequently her interests moved to working on a general theory of vibrations of a curved surface which provided the basis for the modern theory of elasticity.
    The transcript and downloadable versions of the lecture 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 are currently over 1,900 lectures free to access or download from the website.

    The Music of the Primes - Marcus du Sautoy

    1:08

    The Music of the Primes
    Marcus du Sautoy, Oxford University
    Thursday, May 8, 2008, at 6:00 pm

    MIT, Compton Laboratories
    Building 26, Room 26-100
    Access via 60 Vassar Street

    Marcus du Sautoy, author of the The Music of the Primes, will discuss the mystery of prime numbers, the history behind the Riemann hypothesis and the ongoing quest to solve it.

    Why did Beckham choose the number 23 shirt? How is 17 the key to the evolutionary survival of a strange species of cicada? Prime numbers are the atoms of arithmetic -- the hydrogen and oxygen of the world of numbers. Despite their fundamental importance to mathematics, they represent one of the most tantalizing enigmas in the pursuit of human knowledge. In 1859, the German mathematician Bernhard Riemann put forward an idea -- a hypothesis -- that seemed to reveal a magical harmony at work in the numerical landscape. A million dollars now await the person who can unravel the mystery of the hidden music that might explain the cacophony of the primes.

    Marcus du Sautoy is Professor of Mathematics at the University of Oxford and a Fellow of Wadham College. He is author of numerous academic articles and books on mathematics. He has been a visiting Professor at the École Normale Supérieure in Paris, the Max Planck Institute in Bonn, the Hebrew University in Jerusalem and the Australian National University in Canberra.

    Marcus du Sautoy is author of the best-selling popular mathematics book The Music of the Primes published by Fourth Estate in 2003 and translated into 10 languages. It has won two major prizes in Italy and Germany for the best popular science book of the year. His new book Finding Moonshine: A Mathematician's Journey Through Symmetry is also published by Fourth Estate and was released in March 2008.

    Mathematical History: Triangular Relationships - Professor Patricia Fara

    48:49

    And first, the fair PARABOLA behold,
    Her timid arms with virgin blush unfold!...

    Mathematical poetry may seem an unlikely form of satire, but 'The Loves of the Triangles' (1798) was not only a clever parody of Erasmus Darwin (Charles' grandfather) but also a powerful political commentary expressing contemporary fears of revolution and evolution.

    From One to Many Geometries - Professor Raymond Flood

    1:2:49

    For 100 years up to the end of the 19th century the study of geometry was completely changed with the development of non-Euclidean geometries and the use of techniques to think of geometries in higher dimensions - a development essential to Einstein in his development of the theory of General Relativity.

    MathHistory21: Galois theory I

    43:54

    Galois theory gives a beautiful insight into the classical problem of when a given polynomial equation in one variable, such as x^5-3x^2+4=0 has solutions which can be expressed using radicals. Historically the problem of solving algebraic equations is one of the great drivers of algebra, with the quadratic equation going back to antiquity, and the discovery of the cubic solution by Italian mathematicians in the 1500's. Here we look at the quartic equation and give a method for factoring it, which relies on solving a cubic equation. We review the connections between roots and coefficients, which leads to the theory of symmetric functions and the identities of Newton.

    Lagrange was the key figure that introduced the modern approach to the subject. He realized that symmetries between the roots/zeros of an equation were an important tool for obtaining them, and he developed an approach using resolvants, that suggested that the 5th degree equation was perhaps not likely to yield to a solution. This was confirmed by work of Ruffini and Abel, which set the stage for the insights of E. Galois.
