In this episode, we are donning our lab coats and gaining access to the secrets of particle physics. We visit 1932, an astonishing year in the history of science across the world, from Carl Anderson’s rooftop cloud chamber in California, to Marietta Blau’s mountaintop experiments in Austria, via the Cavendish Lab at the University of Cambridge.

Our guest is Dr Suzie Sheehy. Dr Sheehy is unusual for Travels Through Time – she is a scientist rather than a historian – but she is also quite unusual within her own field of accelerator physics. Firstly, because she is a woman, and secondly because she is a brilliant communicator, able to beautifully articulate the wonder and complexity of Physics.

In her new book, The Matter of Everything, Twelve Experiments that Changed Our World she tells the major discovery stories of the past century: the cathode ray tube that brought us television, splitting the atom, finding new particles and, of course, the Large Hadron Collider and Higgs Boson. Behind each of these breakthroughs are the brilliant scientists whose curiosity and persistence made them possible.

Show Notes

Scene One: 2nd August 1932. The discovery of the positron, Carl Anderson, at Caltech in America.

Scene Two: 14th April 1932. Cavendish Laboratory, Cambridge, the splitting of the atom Ernest Rutherford (at almost the same time James Chadwick discovers the neutron in the same lab!).

Scene Three: 1932. Hafelekar observatory, Marietta Blau and her assistant Hertha Wambacher place 'emulsion plates' 7,500 feet above sea level, near Innsbruck, Austria. They would go on to have a huge impact scientifically, but as women their work was undervalued and overlooked at the time.

Momento: Marietta Blau’s diaries so Dr Sheehy could write about her and fully reveal her genius and achievements to the world.
