This is evidenced by his reclusive lifestyle and lack of social interaction. Author of. Working within the framework of Newtonian mechanism, Cavendish had tackled the problem of the nature of heat in the 1760s, explaining heat as the result of the motion of matter. Even during the Royal Society dinners, which were the only social gatherings he attended, this remarkable chemist was found lurking in the empty corridors and sneaked in when no one was noticing. On 24 November 1748, he entered St Peter's College, University of Cambridge, but left three years later. Henry Cavendish. Henry Cavendish was styled as "The Honourable Henry Cavendish".[3].

Soon after the Royal Institution of Great Britain was established, Cavendish became a manager (1800) and took an active interest, especially in the laboratory, where he observed and helped in Humphry Davys chemical experiments. He then calculated the average density of earth to be 5.48 times greater than density of air, a calculation that only differs by 10% to modern day calculations made using sophisticated instruments. He conducted a famous experiment meant to discover the weight of the Earth, an experiment that has come to be known as 'The Cavendish Experiment'.
