Between 1834 and 1838 Schwann carried out experiments to probe the phenomenon of spontaneous generation of life, which was widely believed to be responsible for microorganisms. In one experiment he took a broth of nutrients and sterilized it by boiling. He also heated the air above it to a high temperature. The result was that no microbes grew and no biological or chemical activity were observed in the broth either. This experiment convinced Schwann that he had killed all the microbes and no more could be produced, so the theory of spontaneous generation was incorrect.

Assuming SI units , F is measured in newtons (N), m 1 and m 2 in kilograms (kg), r in meters (m), and the constant G is approximately equal to 6989667400000000000♠ × 10 −11  N m 2 kg −2 . [29] The value of the constant G was first accurately determined from the results of the Cavendish experiment conducted by the British scientist Henry Cavendish in 1798, although Cavendish did not himself calculate a numerical value for G . [3] This experiment was also the first test of Newton's theory of gravitation between masses in the laboratory. It took place 111 years after the publication of Newton's Principia and 71 years after Newton's death, so none of Newton's calculations could use the value of G ; instead he could only calculate a force relative to another force.

After the Civil War ended in 1646, Locke aged 14, was sent to Westminster School in London. He was an able student and was elected a King’s Scholar for his academic merit – a form of scholarship. However, he did not particularly enjoy his time at school; he later wrote a pamphlet “ Some Thoughts Concerning Education ” (1693) criticising the emphasis of public schools on corporal punishment and a dry, narrow, academic outlook. Locke felt education should promote more than book learning, but good morals and the development of reason.
