| | | | | This post will be my attempt to explain intuitively what is Quantum Field Theory. This idea came to me after reading two books: "QED: The Strange Theory of Light and Matter" by Richard Feynman, and "Quantum Field Theory in a Nutshell", by A. Zee (that I only started). Both books use path integrals, but in a very different way: Feynman tells us that the particles can move anywhere they want in space and time, while Zee uses conventional 'forward in time only' paths but of a 'mattress' and not just one par... | |

| | | | | I've said something like this before, but here's another way to say it. The problem of quantum gravity is one of the most famous problems in physics. You've probably heard someone say that quantum mechanics and general relativity are fundamentally incompatible. Most likely, this was narrated over pictures of a foaming, fluctuating grid of space-time.... | |

| | | Consider a monic polynomial with integer coefficients: $latex p(x)=x^d + a_1 x^{d-1} + \cdots + a_{d-1}x + a_d$, $latex a_j \in \mathbb{Z}$.The complex roots of such polynomials are called algebraic integers. For example, integers and the roots of integers are algebraic integers. Note that the Galois conjugates of an algebraic integer are also algebraic integers.... | ||
