The literary convention that numbers less than 10 should be given in words is often highly unsuitable in mathematics… The excessive use of the word forms is regrettably spreading at the present time. ~ J.E. Littlewood 1885 – 1977 - Mathematician
Physics is actually too hard for physicists. ~ David Hilbert 1862 to 1943 (Mathematician)

I have eaten 2/3 of 1/3 of my food ration. 7 remains. How much food did I start with? ~ Cuneiform Babylonian mathematics exercise 1900 – 1600 BC
Actually everything that can be known has a Number; for it is impossible to grasp anything with the mind or to recognize it without this. - Philolaus c. 470 – c. 385 BC Scientist and Philosopher

Chemists do not usually stutter. It would be very awkward if they did seeing that they have at times to get out such words as methylethylamylophenylium. ~ Sir William Crookes - 1832 to 1919
No two electrons in the same state? That is why atoms are so unnecessarily big and why metal and stone are so bulky. (Explaining that atoms are as large as they are because of Wolfgang Pauli’s Principle.) ~ Paul Ehrenfest 1880 – 1933
Chemistry begins in the stars. The stars are the source of the chemical elements which are the building blocks of matter and the core of our subject. ~ Peter Atkins - 1940 to present
