ResourceOn This Day - Nov 23 : Henry Moseley was born
He developed a law concerning the characteristic X-rays that are emitted by atoms, and thus allowed atomic numbers to be defined. Until this point, these numbers in the periodic table were simply an element’s place, rather than being associated with a physical property.

ResourceOn This Day - Jan 25 : Robert Boyle was born
He famously discovered that the volume of a gas is inversely proportional to its pressure (Boyle’s Law) and, together with Robert Hooke, invented the vacuum chamber. Boyle was also a founding member of the Royal Society.
