#Science of #Silicon avec la #MonicaGrady

Silicon
In Our Time

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.

It really feels like the end of an era: Melvyn Bragg is leaving his role as host of "In Our Time". 🙁

Melvyn Bragg has left some really big shoes for Misha Glenny to fill 😬:

“Misha Glenny To present BBC Radio 4’s In Our Time” [2025], BBC (https://www.bbc.com/mediacentre/2025/misha-glenny-in-our-time-bbc-radio-4).

When I feel sad and angry about the BBC's willingness to be Nigel Farage's megaphone, I try to save myself from plunging into despair by remembering the kind of broadcasting which Melvyn Bragg exemplifies.
