Has do you brace a structure to make sure that it doesn’t distort when loaded? And, more importantly, how can we prove it without trial and error? Robin Wilson, Gresham Professor of Geometry, explains how a good diagram and simple graph theory can solve this seemingly difficult problem.

This is the 22nd part of ‘A Millennium of Mathematical Puzzles’.
The full lecture is available (in 24 parts) here on YouTube, or it can be downloaded (like all of our lectures) in its complete form from the Gresham College website, in video, audio or text formats:
http://www.gresham.ac.uk

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.

The introduction to a series of four videos about Evolution, and how evolutionary mathematics not only explains how evolution itself works, but also can explain animal behaviour, altruism and even why morality exists. Although about mathematics, the videos are NOT difficult to follow for those not mathematically inclined…..

Finding math difficult because you don’t have a grasp of the basics?
Learn your 1 to 12 (1,2,3,4,5,6,7,8,9,10,11,12) multiplication tables with GCSE Maths Tutor.
Play this video of tables 1 to 12. For best results say them out loud. Repeat them all at least once every day for a week.
No matter what method you use to learn your tables(even if you use your fingers) they are a cornerstone of arithmetic. To do math with confidence and speed you must have these at you fingertips and use them without thinking.
As well as the complete set of tables in one video, individual tables can be downloaded from:
www.gcsemathstutor.com
These are of much higher definition.

I discuss and solve a challenging integral. The method involves differentiation and then the solution of the resultant differential equation. The so-called Leibniz rule for differentiating integrals is applied during the process. Such an example is seen in 2nd-year university mathematics.

“Fermat’s last theorem is strikingly different and much more difficult to prove than the analogous problem for n = 2… The fact that the problem’s statement is understandable by schoolchildren makes it all the more frustrating, and it has probably generated more incorrect proofs than any other problem in the history of mathematics. No correct proof was found for 357 years, when a proof was finally published by Andrew Wiles in 1994. The term “last theorem” resulted because all the other theorems proposed by Fermat were eventually proved or disproved, either by his own proofs or by other mathematicians, in the two centuries following their proposition.”

For Professor Xiu Ye, approximation is the key to solving life’s mysteries. There are so many variables, she says, the key is understanding the problem to be solved and then getting the closest approximation possible.

Dr. Ye’s specialty is applied mathematics — specifically numerical analysis — a field she says is difficult for non-mathematicians to appreciate.

“Most of the time, people don’t understand what we’re doing with math,” she said. “The research is different. We’re solving problems with a pencil and paper, but our work applies to real world problems also.”

Many times, mathematics and statistics researchers do not receive grants, Dr. Ye said, but she has been one of the fortunate ones, garnering a $61,000 grant from the National Science Foundation. In the competitive field of professional academics, Dr. Ye has produced 40 scholarly papers that have been accepted for publication. Six of those have been published in the top journal for mathematics scholars, the SIAM Journal of Numerical Analysis.
