answered There seems to be no definition of “stability” in axiomatic QFT. Is there? And, if not, is this a problem?

comment Time evolution in quantum mechanics
Is the question about the differentiability of exponential functions of operators? Or about the definition of exponential functions of operators? Or what can be done with the "formal" solution to get more information about the time dependent behaviour of the system?

comment Number of dimensions in string theory and possible link with number theory
Sorry for being off-topic, but I thought the relationship I mention interesting enough in the given context in its own right.

comment What is the status of applying numerical analysis to QM/QFT problems
A good start place to start is Heinz J. Rothe: "Lattice gauge theories. An introduction."

comment Why is there a search for an exchange particle for gravity?
@Daniel: Indirect evidence for gravitational wave emmision: yes. The existence of gravitational waves is not identical to the existence of gravitons, there is one additional conceputal step (gravitational waves exhibit particle wave duality in the quantum realm with the graviton being the particle). It's not one and the same concept.

comment Does string theory provide quantitative experimental predictions?
"Extra Dimensions" is not an (Gedanken-)experiment, an Gedankenexperiment would be "what would we see if we had a magnifying glass for the Planck scale" (no extra dimensions, I'd guess, because photons ignore those).

comment What is the 4th dimension?
Dear Cameron, this question will be answered in any introductory class to physics, which means that it is not appropriate for this site, which is for students and researchers (see faq). In case you are not a student of physics: there are a lot of nice introductions to special relativity for non-experts, like N. David Mermin:"Space and Time in Special Relativity". I'm voting to close.

comment CFTs and formalizing quantum field theory
@Matt: Yes, vertex algebras formalize 2d CFTs. I assume you allude to the work of Connes-Kreimer on renormalization? That seems to be widely ignored by physicists - just like AQFT :-)
