Opportunity to purchase new experiments

Steven J. Koch 02:22, 11 September 2007 (EDT):As I mentioned in class, there is an opportunity to obtain funding to purchase another experiment for the lab. My deadline to submit proposals is Thursday, September 13, so I think perhaps we could obtain the experiment before the end of the semester. So, I am soliciting ideas from students. If I think your idea would fit well into the course, I will then submit the idea up the bureaucratic chain. If not, your suggestion may be appropriate for another lab. Here are some places to look (links courtesy of Professor Bill Miller, the professor helping out a ton in the lab):

• PASCO
• Klinger Educational Products
• Teachspin

Dark labs and taking notes on wiki

Two labs in particular, the e/m ratio and electron diffraction labs, are very hard to conduct even with only the light from the Balmer series and Plank's constant experiments going on in the room. Unfortunately, the Dark room is the same room where all the shiny new computers are at as well. I remember even using tiny flashlights to take down written notes was annoying for the dark labs, since it took some time to readjust to the darkness. Editing the wiki during the experiments will be even more of a pain if done improperly. What will be the procedure for taking down notes during dark labs?--Tomas A. Mondragon 17:12, 10 September 2007 (EDT)

• That's a great question and thanks for thinking of problems ahead of time...unfortunately, my quick answer is: I don't know! Do you have ideas? My opinion with the e/m ratio is that it can be done while using the computer (maybe they improved it by adding a light to see the scale?). And so far the electron diffraction lab isn't working. So maybe it won't be too much of a problem? Here are a couple ideas: (1) Since the monitors are LCDs, it's possible they can be turned down. (2) we could purchase some kind of dark plastic to make the monitors dark. Does anyone else have ideas? Well, these first two weeks will go a long ways towards figuring these kinds of things out, and I appreciate everyone's creativity, patience, and hard work!--Steven J.

A site for the operations of the oscilloscope

here is a link to a website where the expected value of the RC constant for our osicilloscopes is most likley located users manual.

• Thanks, Kyle!--Steven J. Koch 00:52, 5 September 2007 (EDT)

Evenly matched

I reorganized the People page by Mondays and Wednesdays, and couldn't help noticing that if we split me and Devon up, we can play some kind of game with 9 people on a side. I feel like we should play softball or something.--Steven J. Koch 00:22, 29 August 2007 (EDT)

• Or, we could recruit students from my biophysics lab and have 22 total people for football: one offensive squad and one defensive squad. Then we could play Michigan and beat them 34-32. Ha ha ha ha ha ha. Yes, I went to Michigan: tease me about this at your own peril.--Steven J. Koch 00:52, 5 September 2007 (EDT)

I forgot

Hey Steven. After all that I ran out of lab without having you sign my yellow card. How about I catch you at the end of Wednesdays lab, so I can get that taken care of? --Brian Ritter

• That should be fine. Or anytime during Wednesday lab is OK to come by.--Steven J. Koch 15:09, 28 August 2007 (EDT)

i can switch

But, the wednesday class is full in loboweb. maybe we can both drop our classes monday and add the ones we want right after class?--Anne Ozaksut 14:36, 27 August 2007 (EDT)

Yeah I'll switch...

For an A! Just kidding. I went to one of the Consortium seminars for the first time this monday at 2 in the room next door to 184, and it was SO COOL. I really want to start attending those. I'm definitely interested in switching lab days with someone, but I need to clear it with my job first. I'll let you know what happens this weekend.--Anne Ozaksut 00:43, 22 August 2007 (EDT)

• Thanks, Anne! If it works out, that is great. Everyone else in Monday lab, please let us know if you can switch, too, in case it doesn't work out for Anne.--Steven J. Koch 01:17, 22 August 2007 (EDT)
  • PS: That is great that you enjoyed the Consortium seminar!

Too many peeps in the Monday session

Hi Everyone: We have too much demand for the Monday lab session, and there is currently at least one student who cannot enroll. Are there any students who are able and willing to switch to the Wednesday session?--Steven J. Koch 12:55, 21 August 2007 (EDT)

The middleman

What is the page reached by the link "____'s page" for if all it has is a link to our notebook? Shouldn't the link "____'s page" become "My lab notebook" to cut out the middleman? Or will we use the middleman for something else in the future? --Bradley A. Knockel 12:41, 21 August 2007 (EDT)

• Yeah, I hear you. I put the middleman in there "for something else in the future," just like you said. Not sure what, though. Actually, now I remember: it will be a good place to link to your lab reports and / or presentations.--Steven J. Koch 12:48, 21 August 2007 (EDT)
