The Lorentz group, a Lie group on which special relativity is based, has a wide variety of representations. Many of these representations, both finite-dimensional and infinite-dimensional, are important in theoretical physics in the description of particles in relativistic quantum mechanics, as well as of both particles and quantum fields in quantum field theory.
This representation theory also provides the theoretical ground for the concept of spin, which, for a particle, can be either integer or half-integer in the unit of the reduced Planck constant ℏ. Quantum mechanical wave functions r...

From 't Hooft's String Theory lecture notes (paraphrased):
To understand hadronic particles as excited states of strings, we have to study the dynamical properties of these strings, and then quantize the theory. At first sight, this seems to be straightforward. We have a string with mass per ...
i think it is appropriate to say that newton was misguided and actually was high on maal whilst undergoing this experiment thus should be renamed maaal's rings since it makes more logical sense.
Rigor is clarity of concepts and precision of arguments. Therefore in the end there is no question that we want rigor.
To get there we need freedom for speculation, first, but for good speculation we need...

This may seem a silly question, but it has always stricken me as odd that chicken should dry out when I boil it in water. Intuitively it just seems weird, but thinking about this a bit while cooking just now, it also makes little sense to me from a basic physics point of view. I googled this firs...
