Dr Mark Miodownik presents the 2010 CHRISTMAS LECTURES®.
From the very large to the very small, the Kings College London scientist investigates why size is an important factor for both living and non-living matter.
Beginning his journey into the world of scale with a furry friend, Mark reveals why hamsters fare better than humans when jumping from the top of a skyscraper. We find out why mountains don't grow any taller, why the size of an elephant means it has trouble dancing, and why ants can lift many times their own body weight compared to humans.
Plus, Mark scales down to the molecular level to reveal why chocolate tastes so good and returns again to explain how sperm whales – one of the world’s biggest animals – have developed nifty ways of diving deep into the ocean.
On giving the lectures, Dr Miodownik said:
"I'm delighted to be delivering the CHRISTMAS LECTURES®. I watched the lectures when I was small and it feels amazing to be on the other side of the show. Hopefully, they will continue to inspire another generation of young scientists."
The CHRISTMAS LECTURES® in 2010 were originally broadcast on BBC Four and were sponsored by Microsoft Research.
