WW1 happened right when modern physics (quantum mechanics and relativity) was being born. This was a time when figures such as Scrödinger, Bohr, Einstein, Curie(s), Dirac, Heisenberg, Pauli, de Broglie, Ehrenfest, Lorentz, Planck (and the list goes on and on) were all alive, well and doing great new physics. To make my question a bit more specific: how did WW1 affect the people that later ended up in this famous photograph (October 1927 Fifth Solvay International Conference on Electrons and Photons): https://i.imgur.com/UaFMHdu.jpg . Also, we need specials on like... all of these guys! Especially Einstein and Bohr and Schrödinger and Heisenberg and damn it I am making a huge list again, sorry, it's just so hard to leave any of these people out. Or how about a special on the history of physics during WW1? And a long one at that! There was a lot of really important stuff going on in the world of physics back then and it would be criminal to not talk about it in exhaustive detail at some point.
