Discussion: What labs do you do to measure k and h?

I'm just curious which method(s) you use at Reed for your student labs on these things, since they show up so many places in physics. For instance, for k you could be looking at things as different as Brownian motion of microspheres in suspension, or looking at resistor noise vs temperature and bandwidth, while for h you could be doing some version of a Franck-Hertz experiment, or perhaps quantized conductance between point contacts, for example. How many students do you have in a given physics lab section, and do they work as individuals, or in small groups?

And, on a separate issue, nice that you seem to have found a house just a few hundred meters from campus! Should be very convenient. I'm sure you are looking forward to moving in soon.

Resistor noise vs temp and bandwidth for k and photoelectric effect at different frequencies for h. (Ok, so actually the latter really measures h/e.) We'll have ~11 per lab section, working in pairs. (Hm, and perhaps a group of 3.) Also need to teach them all about doing something reasonable for data analysis - we don't really require much from our first-year labs, but then crunch time in the 2nd year!

And yes, house is nearby, totally looking forward to it!
