Title: Exploring the Universe with Cosmic Rays


1
Exploring the Universe with Cosmic Rays
  • Jim Linnemann
  • Professor of Physics
  • Frontiers of Science
  • MSU, Oct 16-17, 2003

2
Overview
  • History and Physics of Cosmic Rays
  • The Milagro Experiment
  • A Bit on the Cosmos
  • Resources

3
Thanks to Colleagues
  • Dan Claes, of U Nebraska CROP project
  • Sarah Eno, D0, Quarknet, U Maryland
  • Jordan Goodman, Milagro, Quarknet, Umd
  • Gus Sinnis and many Milagro Colleagues

My Goals for class
  • Share my enthusiasm
  • How my first field of high energy physics
  • science of the very small
  • connects with my second field of astrophysics
  • science of the very large
  • A flavor of mindset and methods of physics
  • Welcoming you to my world
  • Where extrasensory perception is a daily fact
  • Provoke, and try to answer questions!

My Background
  • Grew up on a farm
  • St. Louis U, Cornell
  • 6 years at CERN (Geneva Switzerland)
  • MSU since 1984
  • http//www.pa.msu.edu/people/linnemann/
  • Living in Haslett daughter in 3rd grade
  • High Energy Particle Physics
  • D0 experiment at Fermilab (Chicago)
  • starting a MSU program in Cosmic Ray physics
  • Sabbatical on Milagro, in Los Alamos, New Mexico
  • Im an experimenter
  • Build apparatus, perform experiments, test
    theories
  • I enjoy collaborative and international research

6
Your Background?
  • Do you teach High School?
  • Took physics classes in college?
  • Do you teach physics?
  • Goals for class for you?
  • What else would you like me to know?

7
A random example of the power of mathematics
  • The same equation
  • Governs the radioactive decay of Carbon 14
  • The loss of obsolete words in a language
  • Is this a wild fluke?
  • There is an underlying unity between the
    phenomena
  • number lost per unit time is proportional to the
    original number
  • Provided by an English major friend, at a
    cosmology lecture
  • A remark by one of her linguistics professors
