Chris Parkes Victor Weisskopf 1908-21/4/2002 Quantum mechanics pioneer Assistant to Pauli, Bohr, Schrödinger Manhattan Project, later peace campaigner CERN Director General "When life is very bad, two things make life worth living – Mozart and quantum mechanics."
Chris Parkes Anti-Hydrogen – CERN Press release 18/9/2002 Anti-protons, anti-electrons (positrons) standard tools in particle physics BUT first production of anti-atoms Do they behave same way as atoms ? ATHENA Charged particles stored by electromagnetic fields But not neutral atoms Anti-H atoms annihilate on walls of vessel Nature Vol. 419, p 456 - 459 (03 Oct 2002)
Quantum Uncertainty Max Planck – Inventor of QM ? Black Body Radiation Eqn (1901) Energy emitted in bundles of energy Energy is QUANTISED Hence birth of QM…. But actually…. The paper does not stress quanta, never says E=nhv “a purely formal assumption”, Planck 1931 In 1901 nobody noticed the quanta ! Historical revisionism! So what was first “Quantum” paper ? 1905, Photo-Electric Effect, Einstein Realised quantum nature of Planck’s theory
