Connection between Bohr model and De Broglie wavelength
I'll just put this here in case I find motivation to work on this. At a minimum, the connection should be explained more clearly in both Bohr model and Louis de Broglie, with mention that this connection was proposed by De Broglie himself along with what is now known as the De Broglie wavelength, and was a major factor in the latter's acceptance.

n&lambda; = 2&pi;r and &lambda; = h/p &rArr; nh = 2&pi;rp &hArr; L = rp = nh/2&pi;
