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.
There has to be evil so that good can prove its purity above it
Even if you are on the right track, you’ll get run over if you just sit there
Be the change that you wish to see in the world
We can easily forgive a child who is afraid of the dark; the real tragedy of life is when men are afraid of the light
All truths are easy to understand once they are discovered; the point is to discover them
I have far more confidence in the one man who works mentally and bodily at a matter than in the six who merely talk about it
