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.
I closed my mouth and spoke to you in a hundred silent ways
He who learns but does not think, is lost! He who thinks but does not learn is in great danger
The more man meditates upon good thoughts, the better will be his world and the world at large
If you have ten thousand regulations you destroy all respect for the law
Not everything that can be counted counts, and not everything that counts can be counted
The truth is rarely pure and never simple
