*/"/**Chiral molecules revisited/"/*

*//*

*//*

*//*

*/Abstract:/*

/According to Hund (1927) quantum mechanics forbids the existence of 
stable optically active (chiral) molecules as they violate the 
invariance under parity of the Hamiltonian. This paradox has attracted 
much attention ever since and there is not yet a universally accepted  
explanation. I will contend that spontaneous symmetry breaking provides 
a qualitative and quantitative explanation. A second paradox concerning 
chiral molecules is the predominance of left handed molecules in living 
matter. This reminds of  the predominance of matter over antimatter in 
the universe. I shall briefly discuss how spontaneous symmetry breaking 
in non equilibrium may offer a clue./*//*
