UNC-CH P&A Classes Physics and Astronomy

Physics 201 (Basic Mechanics)

Text: Classical Mechanics (JR Taylor) -- -- -- note there are errata at the textbook website ,
Supplementary: Marion, Spiegel, Wells, Symon, Boas (reserved in Brauer)
Mathematical formulae: Dwight (QA310.D5), Prudnikov (QA308.P7813) (reference shelf in Brauer) 


Office hours: (Most) Tuesdays and Thursdays, 10:30-11 (but stop by or email for an appt, if you need it)



Before we start, here is a sure strategy to get the best grade possible -- it never fails:

  1. Read the book before class.
  2. Do all the problems from the textbook. If you don't understand the concepts, doing problems will help to clarify them.
  3. Do problems from other books, too. Schaum's Outlines are helpful resources.
  4. Once you understand the important concepts, think about the ways the equations represent them and can be manipulated.
  5. Link all of the concepts and equations from the chapter together so that you can see the big picture.

All exams: (3-4 problems) open notes (only your own)
Grades: approximately 20% hw problems and 80% exams
Expected mathematical skills:
(1) second order ordinary differential equations
(2) integral and differential calculus on several variables
(3) Fourier expansions
(4) matrix eigenvalues and eigenvectors
(All will be introduced as practical skills as needed with no background.)


There will be no credit for late homework -- if the clock says 12:01, it's late.

Here are a couple of math tutorials:
Tutorials on several topics, MatLab intensive lecture notes

Here are a bunch of little games for you to play with:
various mechanical systems interactive fourier transformer , cute wave tutorials, Fourier Transform  of waves and noise (used in class).
cute wave tutorials,

Articles about fractals and randomness in the world:
"Random Fractals: Self -affinity in noise, music, mountains and clouds,"  Physica D38 (1989) 362-371 (whole volume on fractal stuff)
"Random fractal Forgeries" in Science and Uncertainty, ed Sara Nash (Science Reviews Ltd, 1985).

Books about fractals in nature:
Fractals, chaos, power laws : minutes from an infinite paradise / Manfred Schroeder.

There is a (stolen) simulator for a driven pendulum for anyone who wants to play with it. It's flexible, but slow.
and a "textbook" on chaos

For those who can be discrete, here are the pages from Baierlein's book on the relationship between the Lagrangian and quantum mechanics.

Solving physics problems is a creative activity at its best, not a rote process of following instructions
