In Our Time: 25 Concepts and Theories in the History of Physics

A BBC Radio 4 Collection

De: Melvyn Bragg

Narrado por: Melvyn Bragg

Melvyn Bragg and guests explore the history of physics through its most important ideas and hypotheses

Eclectic, erudite and entertaining, In Our Time is one of Radio 4's most successful programmes, regularly attracting an audience of over 2 million for its discussions on every subject under the sun: from oceanography to Ovid.

In this special themed collection, Melvyn Bragg is joined by guest experts including Simon Schaffer, John Gribbin, Jim Al-Khalili and Sir Martin Rees to discuss 25 of the key laws, principles and problems of physics. Here are examinations of major concepts including plasma, radiation, matter and antimatter and the Second Law of Thermodynamics, as well as discourses on historical theories such as Zeno's paradoxes, the speed of light and relativity. Also featured are analyses of modern developments in physics, including the discovery and growing understanding of the proton, neutron and electron, the controversial breakthrough of nuclear technology, and the search for the holy grail of 20th century physics: the Grand Unified Theory.

Physicists, students of science and knowledge seekers will savour these wide-ranging, comprehensive and accessible discussions, which serve as a springboard to dive deeper into the fascinating fundamental principles that govern our universe.
