Insects walk on water, snakes slither and fish swim. Animals move with astounding grace, speed and versatility, but how do they do it and what can we learn from them? From the incredible efficiency of the wet dog shake to colonies of ants building rafts out of their own bodies, in this talk David Hu shows how animals have adapted and evolved to traverse their environments, taking advantage of physical laws with results that are startling and ingenious.
These online events are free for everyone to access. However, donations are an extremely important source of support for us and we would be most grateful if you are able to contribute. We are a small, independent charity and receive no government funding. Our income from ticket sales and venue hire has been significantly reduced and will continue to fall. Donations, alongside our membership subscriptions are vital to our development and survival.
Please donate via our JustGiving page. Every donation we receive makes a difference. Thank you for your support.
