Reminds me of a Triffid.

Hello and welcome. I am no longer in Manchester but I was for my PhD.

You maybe better off thinking 4 dimensional in the first place. That way space-time is not created, nor does it need anything to expand into. By expansion we are talking about the "size" of the 3-spaces embedded in the space-time. You can think of our Universe as a series of 3-spaces all piled on to of each other paramaterised by time. There are technicalities here and you cannot always do this in a meaningful way for general space-times. Anyway, there is no violation of any of the rules of relativity when you have expansion of the 3-space at at rate faster that the speed of light. No physical objects are going past each other faster than the speed of light.

The free non-interacting solutions do. In the Dirac picture (which is mathematically ill) you take the in and out states to be plane waves.

Quantum field theory seems to be the best framework for nature we have. Really quantum field theory is a theory of quantum fields not particles, which are rather a derived notion and quite a special one particular to "flat-like" space-times. Mathematically one often deals with the theory rather formally, but that is okay. Even more abstractly, one school of though is that the fields are not the primary objects, but rather the algebra of observables. This gets mathematically tough very quickly and the framework cannot cope with realistic theories.

Depends on how you go about presenting your ideas and how you respond to criticism.

Judas Priest. \M/

No we are not, so get lost! LOL!

Astronomy you mean.

I don't know how it would develop, but I am interested in the work of mathematicians and scientists during the second world war. In particular, I would like to know which mathematicians and scientists were members of the Nazi party. Teichmüller, who was probably the first to apply differential geometry to complex analysis was a member, for example.

What about a section on the history of science and mathematics? This is not something I know much about. What are your thoughts on this?

Is there much real evidence for this? For sure a lot of the Chinese I have met are very intelligent, they are postgrad students in mathematics for example.

I have now corrected the link. It had http twice!

A good resource is Encyclopaedia of Mathematics, edited by Michiel Hazewinkel. It is online and can be found here. I have personally used this Encyclopaedia many times. The entries are written by experts.

Looks like we now have a "readers' wives section"! In all seriousness, I hope you enjoy using these forums.

Nice to see mathematics fans here! Not enough of us I say.

Being in Portsmouth you are in the right place to ask such questions. The Institute of Cosmology and Gravitation is based at the University of Portsmouth.

I think you may not be on the forums that you are looking for.

Great, though I don't believe you. Welcome to the forums.

There was a first edition in the mathematics library at Manchester. When they moved buildings some physics books got left behind and were free for the taking. Someone has the copy. I imagine it is quite a hard book to read, given our developments since including mathematical notation.

Welcome and indeed AC/DC's High Voltage rocks.

Indeed very wide. The PhD in mathematics is a very noble and worthy pursuit.

Isn't that a strange mix, a degree in physics and then a PhD in sociology?

I am a PhD student at the University of Manchester, I study mathematical physics, in particular the geometry of field theory. Loads more info on my website if your interested.

Hello, I am in Manchester! not being a scientist will not be held against you.
