Discover how calculus, geometry and probability can help make life a bit easier for us all. Marcus du Sautoy explores how maths helps us solve problems like the Bridges of Königsburg, neural networks and the quickest way to save someone from drowning. Watch the Q&A: https://www.youtube.com/watch?v=8hRPW0m1k2A Marcus's latest book "Thinking Better: The Art of the Shortcut" is available now: https://geni.us/dusautoy How do you remember more and forget less? How can you earn more and become more creative just by moving house? And how do you pack a car boot most efficiently? Join mathematician Marcus du Sautoy as he interrogates his passion for shortcuts. After all, shortcuts have enabled so much of human progress, whether in constructing the first cities around the Euphrates 5,000 years ago, using calculus to determine the scale of the universe or in writing today’s algorithms that help us find a new life partner. Marcus du Sautoy is the Charles Simonyi Professor for the Public Understanding of Science at the Oxford University, a chair he holds jointly at the Department of Continuing Education and the Mathematical Institute. He is also a Professor of Mathematics and a Fellow of New College. He was made a Fellow of the Royal Society in 2016. This talk was filmed on 8 November 2021. --- A very special thank you to our Patreon supporters who help make these videos happen, especially: Andy Carpenter, William Hudson, Richard Hawkins, Thomas Gønge, Don McLaughlin, Jonathan Sturm, Microslav Jarábek, Michael Rops, Supalak Foong, efkinel lo, Martin Paull, Ben Wynne-Simmons, Ivo Danihelka, Paulina Barren, Kevin Winoto, Jonathan Killin, Taylor Hornby, Rasiel Suarez, Stephan Giersche, William Billy Robillard, Scott Edwardsen, Jeffrey Schweitzer, Frances Dunne, jonas.app, Tim Karr, Adam Leos, Alan Latteri, Matt Townsend, John C.
