Celebrating 90 Years of Quantum Mechanics in Singapore (QM90) Video by Prof CN Yang addressing the audience

摘要

In the digital era that we live in with more and more technological innovations, it is interesting to reflect on the enormous progress that modern physics has made. It all started with Max Planck's suggestion of light being quantized in 1900, which Albert Einstein was the first to really comprehend and use. In the mid 1920's, a revolution was made in physics, when Quantum Mechanics was formulated by Werner Heisenberg, Erwin Schr?dinger, Paul Dirac, and a handful of other young geniuses under the supervision of Niels Bohr, and Albert Einstein with a critical voice. At the famous Fifth Solvay Conference in 1927 on Electrons and Photons, perhaps the most famous physics conference ever, where 17 of the participants either already were or were to be Nobel Laureates, much of the basic formulation was ready and discussed. Never in the history of physics had so much been achieved by so few scientists in such a short time.
