“We in the back are convinced your theory is crazy. But what divides us is whether it is crazy enough to have a chance of being correct. My own feeling is that it is not crazy enough.”• Niels Bohr to Wolfgang Pauli, on behalf of the “gang at the back” –
Columbia University, 1958. The remark was made by Bohr at the
conclusion of Pauli’s presentation of a non-linear field theory
of elementary particles developed by Werner Heisenberg and
himself. Pauli may have unintentionally invited the comment
when he allowed that the idea “might look” crazy. .
