I would like to share an observation that works for both mathematics and theoretical physics. If you're going to be extremely good at some subject , Let's say Quantum field theory or algebraic topology , the only way is to work out everything independently on your own. You know some basic tools...

Well , they said that they have discovered positron excess which is most probably due to dark matter but the possibility that positron excess is due to pulsars has to be ruled out

Methods of solving Partial differential equations , linear algebra , contour integration and special functions are very important .Group theory is very important in particle physics too . All the math you would need is covered in the book " Mathematics of classical and quantum physics "

You will be fine studying jackson at this level . Landau is very good and develop the whole electromagnetic theory from the principle of relativity and lagrangian formalism . I don't think that jackson is very difficult either. It's the problem set that are difficult not the explanations

Yes,but more complicated math is essential to solve more complicated problems .

Hi guys , Is applying to a public college for an undergraduate physics program a good idea if I want to specialize in theoretical physics in the future and do research ? How much does it cost on average ? I don't have the money for other universities and I didn't graduate from a US high school...

Ultraviolet rays have suffiecient energy that they can damage the DNA of the skin cells causing various forms of cellular dysfunction .The most dreadful is skin carcinoma which occurs commonly in light skinned individuals , Burns also occur due to damage to the skin structures and subsequent...

You should train yourself in linear algebra ,fourier transforms and partial differential equations well .they are very important

I learned physics up to (some)quantum field theory on my own without even taking calculus at university

Well , as far as i know they are just teenagers , seemingly christians why did he portray them as traitors?

If he is not insane , Why did he murder all these people ?? What was his motives?

I see , Thanks a lot naima .

Hi guys , I don't know anything in electronics past how to calculate voltage and currents in circuits containing resistors and batteries . I lack the practical knowledge of how to construct real circuits . I want to know how to design real circuits . Can some one please point me to resources on...

Can some one please explain to me equation 2.35 on page 49 in the textbook "Lie algebra in particle physics " How can he extract the 2 Transformation matrices outside the trace operator ?I think there is something wrong Sorry I do not know how to use latex

Hi guys , I found a lot of incredibly useful lecture videos provided by the international center for theoretical physics see http://www.ictp.tv/ However there is one problems . They use a technology called EyA to view the lectures.It creates high quality images of the black board every 6 seconds...
