Literature Definition and 101 Threads

I have been attempting a question about noisy linear dynamical systems lately. Specifically, suppose we are given a linear dynamical system $$ x_t = Ax_{t - 1} + \mathcal{N}(0, \sigma^2) $$ where $A$ is orthogonal, $x_t \in \mathbb{R}^n$, and $\mathcal{N}(0, \sigma^2)$ is a normal distribution...

A conversation on "great one liners from pf members" prompted me to start this thread. How were you introduced to the books? What impact did the books have on you? what age? What is special about them? How do they stand against other works of 20thC literature? and....what did you think of the...

TL;DR Summary: Looking for literature on O(N) vector model Hello, We have been going over the O(N) vector model in my QFT class but the notes are not very detailed and we are not using a textbook. Does anyone know of a good QFT book which goes over this material? I have a copy of Shrednicki...

According to professional scientific literature and to our best understanding, are there any suggestions that entanglement might imply some sort of faster than light signaling between the entangled particles? I know that according to relativity nothing can travel faster than light, but what...

Hi, I will be starting my research in topological QC (based on non abelian anyons following the work of A. Yu. Kitaev). To begin understanding this theory, I need to develop a background in the braiding group used to describe anyons, fault tolerance in quantum computers and probably condensed...

I know about arxiv.org for natural science (is that the right term?) and pubmed for medical science. Is there a similar site for literature and the more softer "sciences"? :)

Hi all, I am looking for a pedagogical (or maybe also historical) paper that describes the attempts of quantizing gravity and the problems that appear along the lines. It is quite interesting to hear from public talks that "when we try to canonically quantize gravity as we did EM we get...

Hello, I want to try studying QM. I have already read Susskind Minimum QM. Now I have some trouble focussing while reading and mild dyslexia. So I only want to read the stuff I need (doesn't everyone?). HOW do I find the right sequence of the right books to progress from basic to more...

The Nobel Prize in Literature 1936 was awarded to Eugene Gladstone O'Neill "for the power, honesty and deep-felt emotions of his dramatic works, which embody an original concept of tragedy." Eugene O'Neill received his Nobel Prize one year later, in 1937. During the selection process in 1936...

Say I want to do molecular dynamics simulations on a crystal of a specific substance. I get on Scopus and search for it, say going back a couple of years with the results, and then I also check the references in these papers. How can I be kind of sure that this background research is adequate?

Preface There are lots of times in physics when we use approximations of a more accurate or fundamental physics theory because it is easier to work with. For example, in quantum chromodynamics (QCD) lots of calculations are done using the Schwinger-Dyson equations rather than the actual...

I need recommendations on literature to read. Basically i do not understand these section of Frank Harary's book on graph theory since the definition of what a boundary and a cycle vector is not clearly defined. I have googled literature on it but I am having a tough time finding the right...

Lately, I've been hooked on Douglas R. Hofstadter's book Gödel, Escher, Bach. In it, he discusses the idea of "strange loops"—often apparent logical paradoxes—and argues that they are the key to understanding consciousness. He includes witty dialogues, as well as examples of "strange loops" in...

The depiction of courtroom proceedings in the TV series "Perry Mason" was unrealistic - but how realistic was the portrayal of courtroom proceedings in the Perry Mason novels? I haven't read many of the Perry Mason novels. In the few I read, Perry Mason, like any good lawyer, settled things...

I mean there's one way to read a book where the author becomes all important to the narrative, (like his/her life, why it was written, the era it comes from, etc) ) and then the other way is where what the author writes has a life of its own, and takes on meanings that the author might not even...

Prompt 3. How do you read the final scene of Thelma and Louise? Is it a fitting conclusion to the film? Does it shed new light on meanings of the road? The main topic in the course is road narratives. I need feedback for my essay. It's just a 3 page essay. I need also new ideas to finish my paper.
