None. This is predicted by existing theories. The setup they have here is basically a waveguide[1][2]. You can show classically, using Maxwell's equations, that the group velocity of a wave of light when confined to a waveguide is less

Yes. In the repo there is a file 'git-icdiff' which runs the following command: git difftool --no-prompt --extcmd icdiff "$@" So you can use 'git icdiff' to get the icdiff display. In general, you can

Why on earth would it take 30 seconds to factor a random 50 bit number? You just check all numbers between 2 and 2^25 (about 32 million). This should take less then a second, maybe two in python. The parent poster likely was thinking 100 bi
