The Big Machines of Modern Physics
2-The Great Accelerators by P. M. S. Blackett , F.R.S.,
Professor of Physics.

Professor Blackett describes the experiments of Cockcroft and Walton in which for the first time an atomic nucleus was spin with particles accelerated .in a laboratory: machine and not by natural radioactivity . He deals with the great machines that have since been built—cyclotron-, synchrotrons,
. and cosmotrons—and refers to the present-day programme of nuclear research in Britain.
