Suppose we have an unknown number of objects. When counted in threes 2 are left over when counted in fives 3 are left over and when counted in sevens 2 are left over. How many objects are there? ~ Sunzi The Mathematical Classic of Sunzi - Chinese mathematics problem from c. 450 AD
Before the Copernican revolution it was natural to suppose that God’s purposes were specifically concerned with the earth but now this has become an unplausible hypothesis. If it is the purpose of the Cosmos to evolve mind we must regard it as rather incompetent in having produced so little in such a long time. ~ Bertrand Russell 1872 – 1970 - Mathematician and Philosopher
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
Benjamin Franklin performed a beautiful experiment using surfactants; on a pond at Clapham Common he poured a small amount of oleic acid a natural surfactant which tends to form a dense film at the water-air interface. He measured the volume required to cover all the pond. Knowing the area he then knew the height of the film something like three nanometers in our current units. ~ Pierre-Gilles de Gennes 1932 to 2007
An experiment is a question which science poses to Nature and a measurement is the recording of Nature’s answer. - Max Planck 1858 to 1947 Theoretical Physicist
But though the professed aim of all scientific work is to unravel the secrets of nature it has another effect not less valuable on the mind of the worker. It leaves him in possession of methods which nothing but scientific work could have led him to invent. ~ James Clerk Maxwell 1831 to 1879
Perhaps it is not amiss to remark that the biologist may not hope to solve the ultimate problems of life any more than the chemist and physicist may hope to penetrate the final mysteries of existence in the non-living world. ~ Edmund Beecher Wilson 1856 to 1939 - Geneticist Biologist
