从海森堡测不准原理的实验开始: 从实验中可以看到,当有光源测定路线,且双孔打开的时候,接收板原波谷处变成了波峰. 对此,广义相对论的解释是:此时电子经过双孔后的轨迹发生了变化.双孔周围的空间弯曲度被光源散发的光子场所扭曲.是的,你没有看错,光子能够扭曲空间,这是广义相对论的推论.因为光子携带能量,而质能等效. 因为双孔周围的空间扭曲度随着光源的打开改变,导致电子轨迹改变,才最终导致统计意义下接收板波形的变化. 如何解释双孔与单孔的不同波形?因为第二孔离第一孔非常近,第二孔周围的空间弯曲可以显著影…
Awesome Courses  Introduction There is a lot of hidden treasure lying within university pages scattered across the internet. This list is an attempt to bring to light those awesome courses which make their high-quality material i.e. assignments, lect…
1.老老实实把课本上的题目做完.其实说科大的课本难,我以为这话不完整.科大的教材,就数学系而言还是讲得挺清楚的,难的是后面的习题.事实上做1道难题的收获是做10道简单题所不能比的. 2.每门数学必修课至少要看一本参考书,尽量做一本习题集. 3.数学分析别做吉米,除非你太无聊,推荐北大方企勤的习题集.此外注意一下有套波兰的数学分析习题集,是不是搞得到中文或英文版. 4.线性代数推荐普罗斯库列科夫的<<线性代数习题集>>和法捷耶夫的<<高等代数习题集>>.莫斯科…
Deep Learning in a Nutshell: Core Concepts This post is the first in a series I’ll be writing for Parallel Forall that aims to provide an intuitive and gentle introduction todeep learning. It covers the most important deep learning concepts and aims…
When a golf player is first learning to play golf, they usually spend most of their time developing a basic swing. Only gradually do they develop other shots, learning to chip, draw and fade the ball, building on and modifying their basic swing. In a…

Understanding Convolution in Deep Learning Convolution is probably the most important concept in deep learning right now. It was convolution and convolutional nets that catapulted deep learning to the forefront of almost any machine learning task the…
http://mathworld.wolfram.com/HilbertSpace.html A Hilbert space is a vector space  with an inner product  such that the norm defined by turns  into a complete metric space. If the metric defined by the norm is not complete, then  is instead known as a…
此主要讨论图像处理与分析.虽然计算机视觉部分的有些内容比如特 征提取等也可以归结到图像分析中来,但鉴于它们与计算机视觉的紧密联系,以 及它们的出处,没有把它们纳入到图像处理与分析中来.同样,这里面也有一些 也可以划归到计算机视觉中去.这都不重要,只要知道有这么个方法,能为自己 所用,或者从中得到灵感,这就够了. 8. Edge Detection 边缘检测也是图像处理中的一个基本任务.传统的边缘检测方法有基于梯度 算子,尤其是 Sobel 算子,以及经典的 Canny 边缘检测.到现在,Cann…
1 量子计算机与量子编程 1.1 量子计算机 Quantum computing is computing using quantum-mechanical phenomena, such as superposition and entanglement. A quantum computer is a device that performs quantum computing. 所谓量子计算即利用量子力学现象来进行计算,例如量子叠加和量子纠缠.量子计算机是一种执行量子计算的设备. 1.2…
