As described in the book, symmetrical construction was common for children's shoes, slippers, and fancy lady's footwear, while men's shoes typically used chiral left/right construction. $\endgroup$ –

WebNeutrinos can be left-chiral or right-chiral. Physicists have seen only neutrinos born in a left-chiral state, and only right-chiral antineutrinos. So chirality is built in, but helicity is a matter of perspective. Something that could overtake a neutrino—say, a speedy photon—would see the neutrino’s helicity flip. But since humans don ...
