Week 10

End of the the tenth week: Sections 13.1 through 13.3, oscillations.

I plan to demo the sinusoidal motion of a mass on a spring with the motion detector I used earlier in the semester. I also plan to visit a couple sites before/during class to show some applications of this subject matter to simulations of molecular dynamics:

Classical Dynamics of the Benzene molecule (from U of Texas)
I'll probably show the first one; we will discuss "overtones" when we get to a later chapter on waves.
Movie Gallery from U of Illinois (U-C) computational biophysics group
I'll probably show the third one (Bacteriorhodopsin) and/or the fourth one (Estrogen Receptor-DNA binding) because the dynamics is clear and simple, but the sixth one (Avidin-Biotin system) and seventh one (PLA2) are also pretty nice.

These are big files (several Mb), so don't try this on a phone line!
I found these (and lots of others) by Googling "molecular dynamics animation". You can also see this technique used to model water waves in "Finding Nemo"; an explanation of how they used it can be found on Disc 2 of the DVD.

Week 11

Rest of material on simple harmonic motion (Sections 13.3 thur 13.5) plus Sections 14.1 thru 14.7 on waves.

Week 12

Finish up waves (Section 14.7).

Tues 3/30: Exam 3 will be given.

Rest of the twelfth week: Start the topic of fluids with static cases (Section 15.1). Sections 15.2 through 15.4 (Bernoulli's equation for fluid dynamics) with an emphasis on Section 15.3 (Archimedes' Principle) this semester.

Week 13

Mon 4/5: Start thermodynamics (Section 16.1) after doing any Bernoulli examples relevant to the homework.

Rest of the thirteenth week: Sections 17.1 (ideal gas law) along with the relation between kinetic energy and temperature for an ideal gas (pg. 301), making the connection between specific heat (Section 16.2) and the dependence of internal energy on temperature. Section 16.2 on specific heat for solids and liquids is then followed by Section 17.2 on latent heat, where internal energy changes without changing the temperature.

Week 14

Section 17.3 (thermal expansion).
Note that Section 17.3 may or may not be on Exam 4 depending on our progress this semester and what is in the last HW set before the exam. Ditto for Section 16.3 (heat flow), which is another optional topic.
Start unit 5 Sections 18.1 through 18.3.

Thurs 4/15: Exam 4, which covers everything from Section 13.1 to 17.2, and probably Section 17.3.
