My student needs to select either University of Michigan or UMD for his BS degree in Physics. His goal is to go to graduate school after that. His interests are in Nuclear Physics, in particular Fusion energy. He has a full ride to UMD which is also instate. If he were to go to UMI, he will only...

Hey all, What would be a good simulation software for electric circuit labs for intro physics? Software must be free to download. I was pointed to Pspice, but they don't have the light version any more. There is a student version, but they ask students to upload a copy of their student IDs...

Hello everyone, I inherited an old apparatus (featured in this link) and I love it. I used the hot water from the tap and measured ΔT values were very small. Even then the results were reasonable. Now I plan to add a few more to the set. What I found in the internet was the one sold by PASCO-...

Colors around me, in this case green kitchen soap,cooking oil and colored water mixed together, makes me happy :)

Welcome Hiba! PF is a great place for physics students. - Gamma

Absolutely. This is a fictional work although the author has done extensive research on the characters for this book. If nothing else, I have renewed interest in looking into further about the life of this couple. To know that extraordinary people like Einstein have the same challenges and...

I am glad that this Summer I was introduced to an awesome novel, The Other Einstein. The book is the fictional portrayal of Mileva Maric, the wife of my favorite scientist Albert Einstein, and her struggles to balance life and work. The author has done a good job in researching the life of...

Hello, Community college teacher here. I was instructed to employ a laser safety program in my intro physics lab. We mainly use Class II lasers that came with the PASCO Optics table and Laser Ray boxes. One of my adjunct faculty uses Purple and green laser pointers which is classified as Class...

Hi educators, This may sound dumb, but my physics lecture room is our lab as well and we spend long hours in class. We spend approximately 4 hours for lecture and other activities and 2 hours for labs. Currently, I have a strict rule that only drink is allowed during lecture and other...

Hello, Is anyone here familiar with teaching Biophysics or biology/life-science focused physics courses in a two-year institution? We have problem of low enrollment in the traditional physics course - i.e. both in algebra-based and calc. based physics courses! But we have very healthy...

"The formula on y=(x/p)* P* g, P is the density of the fluid, p is the density of the object and x is the mass of the object. I assumed the object would be dropped in water, so P=1, and g is of course 9.83. The equation became y=(x/a)*9.82." The way this problem is setup is bit confusing. First...

Thanks vela! I'll be able to see those when my account is verified.

Hello, I want to find the best free textbook for my algebra-based intro physics courses. Currently I am using Physics-Principles with Applications by Giancoli and I am a bit reluctant to move to open source since I have gotten used to the instructor resources that comes with my current...

Right! Yes, this issue came up because my physics lab is also my physics classroom. We spend lots of time learning and we get thirsty :) Since my room was designated as a lab, recently a rule was brought up to not allow water. In fighting back, we found only hazardous material present is the car...

Yes it is! Thanks so much. Very helpful response! -
