Things are as they are because they were as they were. - Thomas Gold 1920 to present Astrophysicist
Simple laws can very well describe complex structures. The miracle is not the complexity of our world but the simplicity of the equations describing that complexity. ~ Sander Bais b. 1945 - Theoretical Physicist

On the principle of successive variations not always supervening at an early age and being inherited at a corresponding not early period of life we can clearly see why the embryos of mammals birds reptiles and fishes should be so closely alike and should be so unlike the adult forms. ~ Charles Darwin 1809 to 1882 - Naturalist Evolutionary Biologist
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
If your experiment needs statistics you ought to have done a better experiment. - Ernest Rutherford 1871 to 1937 Physicist
Time is the best appraiser of scientific work and I am aware that an industrial discovery rarely produces all its fruit in the hands of its first inventor. ~ Louis Pasteur - 1822 to 1895
In practical applications we are concerned only with comparatively small numbers; only stellar astronomy and atomic physics deal with ‘large’ numbers and they have very little more practical importance as yet than the most abstract pure mathematics. ~ G. H. Hardy 1877 – 1947 - Mathematician
I believe that thirty million of these animalcules together would not take up as much room or be as big as a coarse grain of sand. ~ Antonie van Leeuwenhoek 1632 to 1723 - Biologist
