What Is a Quantum Field Theory ?
Introduction. Quantum field theory began in 1927 with a paper by Dirac [1] in which he sought a framework that would unite the classical electromagnetism of Maxwell with quantum mechanics. Ever since then it has been under continuous scrutiny by physicists, which illustrates the fact that in some ways, physics is more highly focused than mathematics. A mathematician is not forced to work on the...
متن کاملWhat is the Simplest Quantum Field Theory?
Conventional wisdom says that the simpler the Lagrangian of a theory the simpler its perturbation theory. An ever-increasing understanding of the structure of scattering amplitudes has however been pointing to the opposite conclusion. At tree level, the BCFW recursion relations that completely determine the S-matrix are valid not for scalar theories but for gauge theories and gravity, with grav...
متن کاملWhat Good Are Quantum Field Theory Infinities?
A lesson for the new millennium from quantum field theory: Not all field-theoretic infinities are bad. Some give rise to finite, symmetrybreaking effects, whose consequences are observed in Nature. Quantum field theory is the most successful theoretical structure in physics, with applications that range from the short distances of subatomic particles to the microscopic dimensions characterizing...
متن کاملWhat Is Quantum Theory of Gravity?
We present a line by line derivation of canonical quantum mechanics stemming from the compatibility of the statistical geometry of distinguishable observations with the canonical Poisson structure of Hamiltonian dynamics. This viewpoint can be naturally extended to provide a conceptually novel, non-perturbative formulation of quantum gravity. Possible observational implications of this new appr...
متن کاملP-value: What is and what is not
The misinterpretation and misuse of p-value have been increasing for decades. In March 2016, the American Statistical Association released a statement to warn about the use and interpretation of p-value. In this study, we provided a definition and discussion of p-value and emphasized the importance of its accurate interpretation.
