" But, in 1927, Clinton Davisson and Lester Germer in the US and George Thomson in Scotland demonstrated that electrons could interfere with each other, their quantum waves reinforcing and cancelling each other out just like ripples overlapping on a pond. The irony is that George Thomson’s father was ‘J. J.’ Thomson, who had discovered the electron. The father won the Nobel Prize for proving that the electron is a particle; the son won the Nobel Prize for showing that it isn’t. "
