This is how I'm inclined to think of it. But it has a major difference to the usual course work component - you have to obtain the Distinction level to proceed. What I'm asking is that if I get, say, a Merit, will I have to do a second course work in the next University?

The thing is that I would like to do a PhD in Cambridge and to do this I need to do the Part III. However, I would like to know what will happen with me in case I miss the level of Distinction in the examination. I will certainly apply for a PhD in other University but will the courses I did in...

Hi I have just finished a Master degree in Physics and I am looking for a PhD in theoretical physics. Doing this, I eventually came along with the Part III in Cambridge (also known as Cambridge Certificate of Advanced Studies in Mathematics). After reading the information given on the...

As far as I know, a black hole is a singularity in the space-time. The space-time becomes so curved that the geodesics can't get out, i.e., the gravitational field becomes so strong that information can not get out. OK! But what about gravitational waves? As far as I know, gravitational waves...

The mechanism that "makes gravity remain outside the event horizon" is the same one that makes the Earth orbiting around the sun - the curvature of space-time...

But is that because as the universe expand, the curvature in at a point is getting smaller? If we look at the cosmos like a sphere, as the radius expands the curvature in the surface is getting smaller. Is this the interpretation one should give to R? The thing that confuse me more is the...

What is the meaning of the curvature scalar (R) in GR? More precisely, what is the meaning of it's evolution? Why when we are concerning the solar system we take R to be small and when we are concerning the cosmological scales the we assume R to be large? Thanks in advance.

Ok. That was what I thought. I was just wondering if there was another reason for that. Thanks a lot for your replies

Why in every single text about GUT theories only the left spinors are used? Why use the conjugate of the spinor instead of the spinor itself? Is it just a another historic definition? Thanks

I am looking for the theoretical value of sin(2\beta) but I just keep finding the experimental one. I supose there is a theoretical value because I have read that they choose in the BaBar experience the channel B^0\rightarrow J/\psi K^0_S because the theoretical error for sin(2\beta) was very...

How can I write the most general real scalar potential in terms of the singlets and doublets corresponding to irreducible representations of S3?

My question is quite basic... sorry. What is the A_n group? Is it the dihedral group (represented in my book by D_n)? Thanks

Where can I learn more about doublet representation? Are the doublet and spinor representations the same?

I have being studying group theory but I am getting to it quite slowly. Please correct me if I am wrong. When we say that a particle theory is invariant for a given group we are saying that the particles form a representation of that group. So for instance the leptons doublets forms a...

What does it mean to have a model that is SU(2)xU(1)? Does it have anything to do with the electro-weak unification? I asking this because the weak interaction has 2 bosons and the electromagnetic interaction has 1 boson... :confused:
