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:

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.

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.
