There are a fewnew books on reserve in the library

Used Math This covers very practical math for
the sciences geometry, claculus as well as complex numbers and statistics.
You may not see much of the math in this book until later courses, but
the calculus section is useful.

Precalculus Mathematics in a Nutshell
This book focusses on algebra, trig and geometry. These three topics
are essentials for every scientist and engineer. The book does a
great job of explaining the hows and whys and not simply giving you reference
tables.

How Things Work This book covers everything
from seesaws to microwave ovens. It is written in a very casual manner
that makes for easy reading.

Don't forget:

Everybody needs to enroll in the BlackBoard version
of the course. (BTW: The word on the street is that the default password
may not be not be the first 5 numbers of your ID. Try using your
entire ID number.)

Lab manuals are on sale in the bookstore and Seaver
104 (Dr. Saleh). Read the first experiment before coming to lab next
week.

For Monday, turn in the solution (model) to the assigned
problem. Be sure to follow the problem solving algorithm as best
as you can. I'm not expecting perfection on the first assignment,
but do try your best.

A few interesting notes on recent physics discoveries

Scientific American lists their top
science stories of 2001.

Physicists observe the effects of gravity
on small scales. This may lead to a better understanding of how
quantum mechanics and gravity work together.

Scientists continue to better
understand BoseEistein Condensates. BEC is a state of matter
unlike any we experience in our everyday lives. It is one of the
few systtems where we can see quanum effects on the macroscopic scale.
(The 1995 and 2001 Nobel Prizes were awarded to people studying BEC.)
Today:

Discuss the worksheet we did Wednesday and the one due
today.

Instantaneous velocity and average velocity and how
each of these related to position.

Intepreting graphs.

Practice the problem solving algorithm.
