Overview

• Where are we?

  • By 1930, we have arrived at a new space-time description of physical events (relativity) and a new description of the interactions in nature (quantum mechanics).
  • Next step: combine the results of these two 20th century revolutions into a single theory which describes the interactions of the fundamental building blocks of nature.

• Today’s focus:

  • A snapshot of the developments from 1930 to today.
  • Our focus will be on the search for the ultimate particles.
  • The “Standard Model” that describes know particles today
  • Questions that may lead to future discoveries

• Next Time:

  • The Universe as we see it: Galaxies, Stars, Black Holes, ….
  • Evidence for the “Big Bang”
  • The quantum soup in the first moments of the Universe
  • Will the Universe keep expanding? Will it collapse to a point?
