Remember work of Irish physicist
While working in Cambridge, Walton, along with his co-worker John Cockcroft, built the first particle accelerator to split the atom in 1932, earning them the 1951 Nobel prize for physics.
His table top accelerator verified Einstein’s famous equation relating mass and energy, E=mc², and paved the way for later developments in fundamental physics, ultimately leading to the world’s largest accelerator at CERN.
