* Royal Institution Christmas Lectures - Size Matters (2010)

Material scientist Dr Mark Miodownik gives a series of lectures on how size influences everything in science and nature, including the shape of the universe.

Why Elephants Can't Dance
How can a hamster survive falling from the top of a skyscraper, ants carry over 100 times their own body weight and geckos climb across the ceiling? In the first of this year's Christmas lectures, material scientist and engineer Dr Mark Miodownik investigates why size matters in animal behaviour. He reveals how the science of materials - the stuff from which everything is made - can explain some of the most extraordinary and surprising feats in the animal kingdom.

Why Chocolate Melts and Jet Engines Don't
Dr Mark Miodownik zooms into the microscopic world beneath our fingertips, where strange forces dominate the world and common sense goes out of the window. He reveals how this world can make objects behave like magic and discovers the secrets of the extraordinary metals that make jet engines possible. Mark reveals why chocolate is one of the most sophisticated and highly engineered materials on the planet, using special crystals designed to melt in the mouth, and he looks forward to new era of self-healing materials.

Why Mountains are So Small
Why is the tallest building on earth less than half a mile high? Why don't we have mountains as tall as those on Mars? Dr Mark Miodownik investigates the world of the very big and very tall. He reveals that, at this scale, everything is governed by a battle with one of the strangest forces in the universe - gravity. With help from acrobats, levitation devices, spiders and sticky goo, Mark discovers how gravity can make solid rock behave like a liquid and investigates whether it might be possible to build a structure from Earth into space.

* The Joy of Easy Listening (2011)

An investigation into the story of a popular music that is often said to be made to be heard, but not listened to. The film looks at easy listening's architects and practitioners, its dangers and delights, and the mark it has left on modern life. From its emergence in the 50s to its heyday in the 60s, through its survival in the 70s and 80s and its revival in the 90s and beyond, the film traces the hidden history of a music that has reflected society every bit as much as pop and rock - just in a more relaxed way. Invented at the dawn of rock 'n' roll, easy listening has shadowed pop music and the emerging teenage market since the mid-50s. It is a genre that equally soundtracks our modern age, but perhaps for a rather more 'mature' generation and therefore with its own distinct purpose and aesthetic. Contributors include Richard Carpenter, Herb Alpert, Richard Clayderman, Engelbert Humperdinck, Jimmy Webb, Mike Flowers, James Last and others.
