WebThe 2024 Chirality Medal has been awarded to Prof. Ron Naaman . The Chirality Medal, instituted by Società Chimica Italiana in 1991, is awarded annually at the International Symposiums on Chirality to honor … WebHelicity and chirality are not the same thing in the massless limit. They are unrelated. Helicity is an extrinsic physical property related to the alignment of spin and momentum; chirality is related to weak interactions. Chirality is more akin to electric charge or strong color charge than it is to momentum.
