The unprepared mind cannot see the outstretched hand of opportunity
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.
Nothing in life is to be feared, it is only to be understood
Fear not death for the sooner we die, the longer we shall be immortal
Three may keep a secret, if two of them are dead
Everything you can imagine is real
Learning never exhausts the mind
It is painful to realize that while an animal recognizes its master, human beings do not recognize their Lord
