 12/14  Grades are posted! See the link above.
 12/4  We will have a review session in Gal 208 on Sunday afternoon at 2:30.
 10/30  Someone left a textbook in the room (I'm guessing Arash or Gabby?) I'm putting it in Gal 206 (the room with the combo lock), so if you see this, you can get it.
 10/2  I will be available Sunday, October 4 from 3:305pm in Gal 104. Public Safety says they will open the building for us. If they don't,
I'll open the door off the parking lot. Also, you should now be able to study as late as you like on the second floor of Galileo.
 9/28  EXAM 1 will be Monday, October 5
 9/18  There will be a BBQ for physics/3+2/math/CS majors Thursday, the 24th, at 5:30 on the patio in front of Brousseau Hall.
 9/4  I posted scores from inclass presentation of problems. Check these soon and let me know if you have any questions.
 The textbook will be:

 8/31  2.1  Galilean Transforms, Inertial Ref frames

L1: Fill in the algebra (and be prepared to explain) the steps from Equation 24 through 212 in the text.
L2: Derive the unprimed lorentz Transformation Equations from the primed. (Go from equation 212 to 213 in the text.)
L3: Show that the spacetime interval (c Delta_t)^2  (Delta_x)^2 is invariant.
L4: On earth, an explosion happens at point A. 1microsecond later, there is a second explosion at point B.
A and B are 600m apart.
(a) A rocket ship buzzes by traveling at speed v relative to the earth. How fast is the rocket traveling if
the two explosions happen at the same time in the rocket's frame?
(b) How far apart are the events in the rocket's frame?
(c) If A and B were 100m apart on earth, is there a frame where the two events are simultaneous?
(d) Comment on your answer.
L5: Particle A hits particle B, which is at rest, producing particles C1, C2, C3,... Cn.
Show the threshold energy for this reaction is: (M^2  mA^2  mB^2)c^2/(2mB) where M=mC1+mC2+...+mCn and mA is the mass of A and mB is the mass of B.
L6: Look up the derivation of the wave equation for a transverse wave on a string. Be prepared to explain it in class.
(It would be great to work with someone else so you could split it up into parts and put it up on the board faster.)
You can find this in most intro booksnot the Knight, however. I also do not recommend the version on Wikipedia.
A good outline of the derivation (might be enough for you to fill in the blanks) can be found
here at the HyperPhysics site.
L7: Show that y(x,t) = A sin (kxwt) is a solution to the wave equation above.
L8: We have said that d^2Psi/dx^2 = k^2 Psi has solutions:
Psi = A sin kx + B cos kx
Psi = C sin (kx + delta)
Psi = D e^(ikx) + E e^(ikx)
(a) Find C and delta in terms of A and B (b) Find D and E in terms of A and B.
( Here is a picture of the
assignment from class.)
L9: Given that Psi1=Bxe^(ax^2) where a=sqrt(mk)/(2hbar) is a solution to the Simple Harmonic Oscillator (a) Find B and (b) Find E, the total energy.
