Thank you for anything you can offer. We've got a plasma globe which we can tie into talking about solar and interstellar plasma, and we have a few Galileoscopes, but we don't really have anything else astronomy-themed. I've been thinking, but haven't come up with many ideas. One idea I did...

Hi guys, I am going to get a shot to perform a short experiment of my choosing with an FTIR device. Do you have any suggestions/seen any interesting things I could use it for? (Please keep in mind my knowledge in FTIR in very limited so I would really appreciate interesting suggestions which...

So my numerical analysis class requires me perform iterations involving huge expressions into my strictly NON-graphical scientific calculator. It often happens so that my current calculator (CASIO fx-911ES PLUS) does not allow me to feed in it a expression which goes beyond its input memory...

Hi everyone, new poster here. I'm a chemist who's in a little over my head with an electrical engineering problem, and I'm hoping someone here might have some advice. The short version (details to follow) is that my experimental setup has a photomultiplier tube (PMT) detector whose output has...

G'day all, I'm a 50-year-old ex-hardware pseudo-engineer. I had 2 years of electronics training back in the early 80s, but since then I've been completely self-taught. I was sharp enough to be offered a position at Hewlett-Packard, in instrument repair, although I was the only team member...

I am a undergraduate student now and I have joined in a project in my college. I was assigned a job to simulate the deformation of an elastic membrane given the boundary and the exerted forces on it. It seems to be a homework problem and quite fundamental, but I really have spent much time on it...

I am helping my son (who is a junior) begin researching colleges. He has always planned to go into engineering, but is now leaning toward majoring in physics. He knows he will need to get a masters degree, and probably a Phd at some point if he stays in physics. When he was looking at...

Hi y'all, I am new to the physics forums. I really like Astronomy and Physics. This is a sort of a homework question but I couldn't find the right category to put it in. I have an english paper due soon and I need to find a topic. The paper is supposed to be about a controversial issue. I've...

The Canon MP560 all-in-one printer that I bought in January 2010 just died on me, I think. When I turn it on, it comes up with a B200 error which seems to mean the print head has gotten fried. The instructions I've seen for clearing that error all start with removing the ink tanks, but I can't...

Hey everyone, I was hoping I could get some input on this. I'm taking an honors section of Calculus I this semester, and part of the course involves a cumulative honors project. It has to be a minimum 8 page paper, at least a third of which has to be actual calculations, about a topic that...
