Bacteria Quote by Anthony Terence Quincey Stewart
“The phrase 'contrary to all expectations' rings through the story of the progress of human knowledge. It was 'contrary to all expectations' that the Earth was found to revolve around the sun, and not the other way round, and that a mould growing in one of Dr. Alexander Fleming's dishes was found to be capable of destroying bacteria. When in 1989 the spacecraft Voyager 2 got close enough to the planet Naptune to take detailed pictures of the surface, they were 'contrary to all expectations'.”
