Silicon
Misha Glenny and guests discuss the biology, physics and chemistry of one of the most abundant elements in the Earth's crust and its impact on our atmosphere and on technology
Misha Glenny and guests discuss the physics, biology and chemistry of the element silicon which is at the heart of some of the most useful and beautiful objects on the planet. While it is still being created throughout the universe, the silicon we have here was made billions of years ago in dying stars. In its compounds we have long used silicon for glass and, more recently, purified silicon has become the foundation of modern electronics. Perhaps less appreciated is the role silicon compounds play in the biology of life on Earth, on the levels of carbon dioxide in the atmosphere and the cycling of elements between land, oceans and atmosphere that sustains us.
