  2. Inquiring minds want to know ... Yo! What holds it together?

  3. Fermi National Accelerator Laboratory (near Chicago)

  4. CDF Minos

  5. Stanford Linear Accelerator Center

  6. Event display from the SLD experiment at SLAC

  7. What forces exist in nature? What is a force? How do they interact? How do forces change with energy or temperature? How has the universe evolved?

  8. Mini-Ph.D. – Quantum Mechanics 101 Lesson 1: Size actually does matter.

  9. Determine the postion and velocity of a car … no problem

  10. Determine the postion and velocity of a small particle … no problem

  11. Problem! Heisenberg uncertainty principle Cannot have perfect knowledge of both the position and velocity Heisenberg

  12. e- Dear Steve, Party relatively hard! -Al The fundamental nature of forces: virtual particles Et  h Heisenberg E = mc2 Einstein

  14. quark-antiquark pair created from vacuum Quantum Chromodynamics QCD relative strength Why bare quarks have never been observed. asymptotic freedom distance energy density, temperature quark Strong color field Energy grows with separation !!! “white” 0 (confined quarks) E=mc2 ! “white” proton (confined quarks) “white” proton Thanks to Mike Lisa (OSU) for parts of this animation
