So, yes, where did he go wrong? We wrote a paper with a brief history of quantum-mechanical ideas, focusing on some of the well-known contributions of great minds – including the ones we already talked about in previous posts – to the Solvay Conferences.
We hope to show there was nothing inevitable about the new physics winning out. In fact, we suggest modern-day physicists may usefully go back to some of the old ideas – most notably the idea that elementary particles do have some shape and size – and that they should, perhaps, try somewhat harder to explain intrinsic properties of these particles, such as angular momentum and their magnetic moment, in terms of classical physics.
The contributions which we discuss are those of Ernest Rutherford, Joseph Larmor, Hendrik Antoon Lorentz and, yes, Louis de Broglie. However, we also singled out Louis de Broglie’s ideas in a more comprehensive but also more technical paper on de Broglie’s wavelength, elementary particles, the wavefunction and relativity.
