Practicalities

• Litterature B.R. Martin G. Shaw, Particle
  Physics(2nd edition), 1997, publ. John Wiley
  Sons Ltd
• Strongly recommended to look at the course
  web-page
• Lots of additional information
• Points to several GOOD introductionary sites

Painless Particle Physics ParticleAdventure.org

• Credits to former teacher Mogens Dam for slides
  etc.
• Non-trivial timetable since both Jens-Jørgen
  Gårdhøje and I have to travel during the course

CERN Summer Student Programme

• A unique opportunity to enjoy a summer in
  Switzerland, learning bleeding-edge science and
  technology and meeting new friends from all over
  the world
• Google CERN Summer Student, or go directly to
  http//humanresources.web.cern.ch/HumanResources/e
  xternal/recruitment/Students/students.asp
• 2-3 months of training at CERN work in a
  research group, lectures, student sessions,
  visits to experiments, workshops,

Particle Physics in a nutshell?

Special relativity
Quantum mechanics

• Formalism is 4-vectors (kinematics)
• Physics content is quantum mechanics
• Plus a big bag of new particles and concepts

APPLIED special relativity and quantum mechanics
9
The MAGIC key

• Natures deepest secret (and we cannot directly
  see deeper)
• Gives us quantum mechanics and string theory
• Add the de Broglie relation l h/p
• Re-define units hc1

The intuitive understanding of particle physics
and its numerical mechanics
