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...
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 ...

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...
That was a short tour of how the packaging there works. For open issues or pain pain points that there might be, there are packages that don’t have any tests. If we are looking at, what was the number, 63,000 packages, I’m not going to test them by hand, so we really rely ...
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 ...
如果一定要学群论,我会考虑Zee的Group Theory in a Nutshell。 当然,如果有人和你大谈微分几何和数学基础,你可以向他/她推荐Spivak的A Comprehensive Introduction to Differential Geometry,并且敦促他/她全部读完本书及其前置之后再开始学习物理。 数学进阶 还不满足?也许你会合适学数学物理!数学物理是往往数学或者数...
