    Sorry, I should have said .33 Farads. I changed it above.

    Solar cell charging a super capacitor - need an equation

    I have a very small solar cell that outputs 4 volts (open circuit) and 50 μA (short circuit). I'm trying to charge a 0.33 F capacitor that is rated for 5 volts. I'm looking to understand the charging relationship. 1. What equations govern the charging of this capacitor? I'm already aware of...

    What if the GRE in Physics is not required?

    I just read your full journal. It helped quite a bit. Thanks.

    What if the GRE in Physics is not required?

    Actually, I did do a search for qualifying exams. What I found, didn't tell me much. It's a multi day exam that everyone loses sleep over. You spend your two years studying for it. Thus, I can only guess it is similar to a bar exam - something that comes at the end of your education. If...

    What if the GRE in Physics is not required?

    I was just informed that the school I was considering for graduate school (really my only option) does not require a GRE. Given that I'm going back to school after 10 years of absence from the field, do I really need to take the GRE? It would make my life a lot easier if I just took some...

    Schools Which courses should I take again to prepare for graduate school?

    Yep, I'm the "lawyer dude". I'm considering about two years on the third and fourth year classes again as a refresher. That way I have most of my foundation intact.

    2005 Nobel Conference and Einstein's Work

    I'll be attending the 2005 Nobel Conference at Gustavus Adolphus College in St. Peter, MN. You can read more about it here. To prepare for the conference, I'd like to read through some of Einstein's papers - particularly those from 1905 or so. I have obtained copies of three papers, but I'm...

    Schools Which courses should I take again to prepare for graduate school?

    I'm planning on entering graduate school to obtain a PhD in elementary particle physics. I graduated in 1996 with a physics major. I have NOT worked in this field since that time - I now have a J.D. instead. I need to refresh my math and physics skills to take the GRE. I would imagine a...

    Programs I want to get a degree in Physics, but I'm scared I fooled around too much

    Wow, I'm impressed. This gives me hope (although I haven't failed any classes...). Still, it takes the pressure of significantly.

    Unraveling Spaceman #1's Atomic Pop Gun Mystery

    You're missing the mass of the string, the increased mass of the cork, and the time needed to accelerate to 99% the speed of light. Also, how did you get the 7x mass number at 99% the speed of light?

    Secure USB Hard Drives - Solutions & Ideas

    The Gizmo drive I purchased from Crucial.com came with a security program that unlocks a hidden portion of the drive. Maybe Crucial can tell you where to get it.

    Anyone a non-traditional student in pursuit of a Ph.D.?

    If I made $401k per year, then I doubt there would be a decsion. The 401k I mention is a retirement plan. Company matched. It is the perk of working for a large corporation. The hard work of a PhD doesn't scare me, it is the giving up of security that is troublesome. I'm going to...
