A partial history of the weak interaction

The weak interaction is said to be responsible for beta decay, where a neutron decays into a proton, an electron, and an antineutrino. All four of these particles are said to be fermions. Fermions are of course named after Enrico Fermi, who proposed what’s now known as the Fermi interaction. That was in his 1933 paper Attempt at a theory of β rays. It was famously rejected by Nature, then published in both Italian and German in 1934. The Fermi Interaction The Fermi Interaction is “the…

A detective story

So why isn't the future what it used to be? I think it’s something of a detective story, one where you have to look back at the history. In 1831 Michael Faraday was doing his ground-breaking experiments, showing how electricity and magnetism were interrelated. Then in 1865 James Clerk Maxwell developed the theory, and in 1880 we had light bulbs courtesy of Joseph Swan and Thomas Edison. In 1905 Einstein gave us E=mc², saying there was an awful lot of energy in matter. Then in 1934…
