Today Lev Landu was honoured by a google doodle. I searched youtube for more videos about this nobel prize winning Russian physicist but there wasn't much in English. However, in these two short videos Edward Teller describes how he settled a theorectical dispute about superconductivity between Landau and Heinsenberg in Landau's favour and how Heinsenberg got "even". ;-)
