What are the hot topics in astronomy and cosmology as measured by production of recent academic papers? I'm not looking for an exact number, just a relative ranking with some sense of order of magnitude. My motive is to get at the whole mainstream v. non-mainstream issue in a way that...

Are there any topics in physics that concerns fire? I need it for some essay.

I am interested in quantum computing, but presently have no clue as to where should I start. Could you suggest some topics in the field for me to go ? Some simple ones that I can finish them in one year ? Could you ? Thanks a lot

Idea ? Hello all! I'm back again...sorry to say...I'm busy these days with my exams...and lots of club works... Ok...I've problem...I want to take research on Computer Science subject...but problem is as we are in South Aisa...we don't get much upto date news about technology...I...

I'm a grade 12 student and have been given the task of teaching our algebra and geometry class for a day :smile: . There are absolutely no restrictions on what I can teach about. It does not in any way have to be related to algebra or geometry, just mathematics in general. What I really need is...

Everytime I try opening a topic here my browser shuts down. So this is just to see what happens if I start the topic I try to get into.

As a student I have grown a curiosity on Research Topics in Mathematics. Anyways I would like to know what are the current Research Topics in Mathematics for Phd students? I just want an idea of what they are researching on, to give me a focus in a particular area of study of the basics...

For the experienced scientists and educators, what are the most useless math topics from a practical standpoint. I would list my favorite: 1. Polynomial long division. If the numerator and denominator don't factor, what is the use of performing the long division? I know of only one...

From favorite to hated: 1. Kinematics / Gravitation / Relativity 2. Conservation of Energy / Vectors 3. Momentum 4. Dynamics 5. Waves / Oscillations 6. Magnetism 7. Electric Fields / Optics 8. Pressure/Fluids... 9. Angular stuff...blech

Hi, I was wondering how and where physics researchers find good research topics in the field of theoretical physics? (and possibly experimental physics too) I'm not talking about obvious holy grail of physics such as 'theory of everything' or cold-fusion.. but some topics that are...

Who can tell me some typical topics in Condensed Matter Physics nowadays?[?]

Hello all, It's time for a little experiment. As part of my constant quest to stimulate discussion and bring more technical content to physicsforums.com, I am going to occassionally provide links to posts from the usenet newsgroup sci.physics.research, which is a moderated internet-based...

Hi I found these forums by accident but I'm happy I did because I'm always ready to talk physics.I am not a phyiscs major or in that field, I did take it in high school and have read some books on relativity and some Hawkins books. I'm looking for the latest information on a few topics.. 1...

I'm asking because I'm trying to get a feel for this forum.

Before the change overmorp FZ, meteor, Hurkyl, dg, Tom, and myself had an interesting forum on photons. As this does not appear to have been revived yet, I have put my almost complete revision of a page on Light on my site. This should be read in conjunction with the page on Bosons. Can we get...
