How wise is it to make your Ph.D. topic on something that can be disproven experimentally maybe in a year or two? I tried to make this question as general as possible, so that it can apply to others who have the same question. Specifically, if I do some calculations or theoretical work in...

Which topic to pick for physics coursework??!? For our physics coursework we can choose any topic around physics to talk about and I am stuck on which one to do. A good topic will be one that I can link many other aspects of physics to it, for example quantum or something else. Previous done...

New topic about Complex Network. Is there Anyone interested in this filed?

I am not sure if I am reading well the following article about KT phase transition in spin systems. http://www.itp.uzh.ch/~llucas/projects/proseminar.pdf Page 5 quotes a theory regarding the Helmholtz free energy function. The curve surrounding a spin site or an atom looks like everyone's best...

Hey, I'm a high school student interested in persuing Physics in college. I just took my AP Physics exam, and I think it went well =]. I realize this isn't a specific homework question, but because it pertains to my AP Physics class I thought it would be appropriate here. Because we took...

This is a bit different kind of help that I need compared to most other threads in this forum. I was not sure of where exactly to post this. But, since it is pretty much homework, and it's for my AP Calculus AB course, I thought this would be an appropriate place to put this thread. If not...

I'm studying AS Physics, and we're doing the sensors project for our coursework. WE can use LDRs, Thermistor, rotary sensor and a variable resistor (length). I have to think of a context to the measurements, and our teacher wants it to be witty and original, but have no ideas! Examples of...

This Tuesday, I am going to walk into my class and take the first test this semester, which also happens to be my midterm. I'm taking Physics 204 - Mechanics and it's pretty much kicking my butt ha ha. The teacher has told us that a "cheat sheet" will be allowed STRICTLY for equations...

I'm going to be choosing the topic of my masters thesis rather soon which will lay a lot of the ground work for my PhD. But I am wondering how general should I make my thesis with respect to other engineering areas. I'm looking to go specifically into energy and heat transfer of...

Does anyone know about the IB Diploma course? We're supposed to make a project or investigation and analyze the physics, chemistry and biology aspect of it... the theme of the project is 'Go Green' and it can be literal (do things involving green things, paint green stuff)... I'm confused of...

I have no where else to go to, and posting anonymously on a public computer seems to be my best bet because I have lurked these forums for a while and believe most members here are intelligent enough to provide an objective answer. As I've already stated, this issue may be sensitive to some...

After doing some research on the subject I have managed to work out roughly how it works. What I havn't been able to find out is what it does. Were there any implications from this effect? Did it lead to disproving or proving a theory? Any help would be very usful.
