CHIP (Computerized Homework in Physics)
There are 28 Homework assignments.
First one is due by noon Friday August 24th
There are 32 pre lecture quizzes
First one is due by 8.30am Wed August 22nd
IMPORTANT Read the QUICK GUIDE TO CHIP handout and login
to the CHIP site today and make sure your Career ID and password
work. There is a much longer guide to CHIP that you can access
from the course home page.
You must also register the serial number of your I Clicker in the
student grade book of CHIP
It is very unlikely that there are any errors in CHIP if it will not
accept your answer then you have made an error. Most common
errors are
Wrong answer, Significant figures, Wrong sign

Who am I
Originally from England
I’m an experimentalist in High Energy or Elementary
Particle Physics trying to find/understand
 The physical laws which govern the Universe
 The fundamental building blocks of all matter
 The evolution of the Universe from the Big Bang to
the present day, 13.6 billion years later
We use
 Particle accelerators which produce collisions with
energy densities the same as a billionth of a second
after the big bang.

liquid Helium (the coldest place in the
entire Universe)
