What is field in field theory?
What is a field theory? A field is a physical quantity that has a value at each point in space and time [from Wikipedia: fields in the physical sense]. Physical quantities can be measured by definition. Fields are described by mathematical functions of space-time locations.
What does quantum field theory study?
Quantum Field Theory (QFT) is the mathematical and conceptual framework for contemporary elementary particle physics. ... In a rather informal sense QFT is the extension of quantum mechanics (QM), dealing with particles, over to fields, i.e. systems with an infinite number of degrees of freedom.
Is quantum mechanics hard to learn?
Quantum mechanics is deemed the hardest part of physics. Systems with quantum behavior don't follow the rules that we are used to, they are hard to see and hard to “feel”, can have controversial features, exist in several different states at the same time - and even change depending on whether they are observed or not.
What math does quantum mechanics use?
The main tools include: linear algebra: complex numbers, eigenvectors, eigenvalues. functional analysis: Hilbert spaces, linear operators, spectral theory. differential equations: partial differential equations, separation of variables, ordinary differential equations, Sturm–Liouville theory, eigenfunctions.
