Nature makes penicillin; I just found it
Scottish biologist, physician, microbiologist, and pharmacologist. His best-known discoveries are the enzyme lysozyme in 1923 and the world's first antibiotic substance benzylpenicillin (Penicillin G) from the mould Penicillium notatum in 1928.
Wise men speak because they have something to say; fools because they have to say something
Some cause happiness wherever they go; others whenever they go
Alone we can do so little; together we can do so much
I discover myself on the verge of a usual mistake
Dislike in yourself what you dislike in others
Either write something worth reading or do something worth writing
