弦理论简介(A Brief Introduction to String Theory) 只看楼主收藏回复 大江大海_1949 酷 3 长久以来,我们生活在熟悉的三维世界,无论什么物体,无论在哪儿,可以左右、上下、前后移动,但电影中的一切有所不同。尽管屏幕中的角色看起来是三维的,其实它们仅“困在”二维空间,因为电影屏幕没有前后之分。更直白地说,电影中的“三
The goal is to provide a practical, "how-to" manual on string theory, string model-building, and string phenomenology with a minimum of mathematics. These notes consist of Part I of these lectures, which cover the construction of bosonic strings, superstrings, and heterotic strings prior to ...

一本入门级别的弯曲时空量子场论书是Introduction to Quantum Effects in Gravity(不过我感觉这书内容没比Padmanabhan的相关章节多什么内容, 我翻这本书唯一的收获就是知道了Unruh效应对应什么物理情境,Padmanabhan同样介绍了这个效应,只是没提Unruh这个名字),更进阶的标准参考是Wald的Quantum Field Theory in Curved Spacet...
Introduction and summary Fifty years ago this month, 't Hooft argued [1] that the large N limit of SU(N ) gauge theories, keeping fixed the 't Hooft coupling λ = gY2 MN , could be equivalent to a string theory with string coupling gstr ≃ 1/N , such that the string theory ...
The goal of these notes is to give a short introduction to Fukaya categories and some of their applications. The first half of the text is devoted to a brief review of Lagrangian Floer (co)homology and product structures. Then we introduce the Fukaya category (informally and without a lot ...
Functional Programming Fundamentals: short introduction to FP and its advantages. OO vs FP, Robert C. Martin, The Clean Code Blog. A pretty interesting take on the differences between OOP and FP from an expert in OOP. OO is not about state. Objects are bags of functions, not bags of da...

1d shows that many documents are rather short, e.g. 25% of the documents are below 14575 characters or 3181 words. However, 200 documents are longer than 1 million characters, 49 documents are longer than 10 million characters and the longest documents are several hundred million words or ...
