Turing Award winner Tony Hoare, computing pioneer who invented Quicksort, dies at the age of 92

An obituary of Tony Hoare, a pioneer and one of the greatest programmers in the early history of computing.

Quantum computing meets the Möbius molecule

Thanks to the alternating single-double nature of the bonds, electrons in these orbitals end up delocalized; the differences between the bonds become a bit irrelevant, and the molecule is best viewed ...
