One can get out of them what one wants if one uses them, and it is they which have made so much unhappiness and so many paradoxes. Can one think of anything more appalling than to say that ...

general-relativity as an effective-field theory
... We are used to the situation where our theories are only assumed to be provisional. They have been tested and found to be valid over a limited range of energies and distances. However, we do not know that they hold in more extremes situations. There are many examples of theories which have been supe ...

Remarkably, these are precisely the constraints that single out relativistic fields appearing in a local QFT (when no conf ...

Time emerges as a uniform parameter that tracks the sequence of actions and we derive a dynamical equation for the qubit. 7. A qubit needs a carrier, a particle of mass m, its presence in the qubit dyn ...

There are solutions to be found, but as Sherlock Holmes once said, “It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories instead of theories to suit fa ...

Interaction of Elementary Particles
