William Thomson, a British physicist, said in his speech at the Royal Society's New Year celebration on April 27th, 900, "The building of physics has been basically established, and future physicists only need to do some tinkering work".

William Thomson was awarded the title of Lord Kelvin by the Queen of England for his scientific achievements and contribution to the Atlantic cable project, and later he was called Kelvin.

William Thomson's research scope is quite extensive, and he has made great contributions in mathematical physics, thermodynamics, electromagnetism, elasticity, ether theory and earth science.

William Thomson did not rest on its laurels. He thinks that two problems are more important: "There are still two dark clouds in the clear sky, one related to blackbody radiation and the other related to Michelson's experiment". Later, quantum theory and relativity were born in these two dark clouds.

At the end of that year, Planck put forward the quantum theory, and five years later, Einstein put forward the theory of relativity, and Einstein also developed Planck's quantum theory into the light quantum theory, which became today's light quantum theory.
