Presentation transcript:

Chris Parkes Victor Weisskopf /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 (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
