(1914) - Carl Fisher, energetic proponent of the Lincoln Highway (first section opened 13 Dec 1913) "The ability to reduce everything to simple fundamental laws does not imply the ability to start from those laws and reconstruct the universe." - Philip W. Anderson, American Nobel prize-winning physicist (born 13 Dec 1923) "Aluminium may probably send tin to the right about face, drive copper saucepans into penal servitude, and blow up German-silver sky-high into nothing." - comment on Deville's new process for industrial production of aluminium by Charles Dickens, writing in Household Words (13 Dec 1856) | |
