In reserve: Allen Morris (15 min)

Each day will comprise two hours of lecture and three hours of lab. Laboratory will consist of lecture demonstration construction projects which you will take with you when completed.

Questions for SMU Faculty

  1. I would like to see a discussion of whether or not mass increases with velocity. Some take the view that it does and particle physics people seem to take the view that it doesn't. Are there any opposing views within the faculty that they would like to air before us?

    Particle physicists look for unique quantum numbers to describe the particles they study: electric charge; spin; lepton number; etc. Since there are only two non-arbitrary speeds in the universe, zero and light speed c, particle physicists label their quarry by the rest mass m0 (measured at zero relative speed) if the particle can be brought to rest. If the particle can't be brought to rest, then it is massless and travels always at the speed of light.

    If you want to define "mass" as "resistance to acceleration" or "gravitational charge," then mass definitely increases with relative speed. A particle physicist would say that the energy of the particle increases with speed.

    E = m(v) c2 = m0 γ(v) c2, where γ(v) = (1 - v2/c2)-1/2

  2. How about updates on the status of the Fermilab built magnet structure that broke during pressure tests at CERN?
  3. How about an update on dark matter and dark energy?
  4. How about someone discussing the advantages of a linear collider as opposed to another ring --- and whether or not hadrons or heavy ions would ever be used in it? Or other particles? Is the main reason for a linear collider so that the smaller particles won't radiate away so much energy?
  5. Maybe a neutrino update? Interesting experiments going on now...
  6. Higgs watch update for Fermilab --- and, if the machine holds out and the luminosity continues to increase, will Fermilab be able to definitely find or at least rule out a Higgs within their energy range and this point the LHC in new directions?
  7. Discussion of the new accelerating technique being developed at SLAC? Wake field in plasma?
  8. How about the rise of grid computing?
  9. What about the efforts to explain global warming by cosmic ray interaction with water vapor? That could be a hot topic...

    This is mentioned briefly in but the details are maddeningly absent.

    "The final hypothesis for solar forcing of global warming involves the modulation of intergalactic cosmic rays by the solar-cycle-dependent interplanetary magnetic field. Reductions in this magnetic field during the minimum of solar activity increases comic-ray penetration into the Earth's atmosphere. It was postulated that during this period of increased cosmic ray penetration, cloud formation would be enhanced through the cloud chamber effect well known to physicists in the high-energy laboratory. An early, surprisingly high positive correlation of increased cloud formation with enhanced cosmic-ray flux stimulated interest in this possibility, but further work with a more extensive database has negated it. This was not surprising, given a large number of other problems with this hypothesis too technical to review here."

  10. The IB Physics curriculum has just been updated including a new particle physics section. In view of this it would be nice for me if someone could lecture on the basics of Feynman diagrams (I can send you the details from the updated curriculum if that would be helpful in pinpointing exactly what I'm looking for).

    Here are some web links:
