《应对气候变化的中国视角》课程组

As the physical quality of life improves in our increasingly global and technologically focused world, it is particularly important to focus on psychology. In fact, psychology is one of the most popular subjects studied in universities by students across the globe, and there is an increasing interest in studying this fascinating - and constantly changing - field.

This course will cover a wide range of topics from the field of psychology to provide a comprehensive introduction to the subject. Course lessons will focus on consciousness, sensation, perception, learning, memory, thinking, emotion, evolution, motivation, personality, social psychology, and happiness. In every lesson, we use empirical studies of psychology and classical theoretical perspectives as examples, concluding the course with the relatively new perspective of positive psychology. In this course, you will gain an understanding of psychological modes of thought and master the basic methods of psychological research, while freeing yourself of psychological misconceptions and misunderstandings.

Despite the large volume of data mining papers and tutorials available on the web, aspiring data scientists find it surprisingly difficult to locate an overview that blends clarity, technical depth and breadth with enough amusement to make big data analytics engaging. This course does just that.

Each module starts with an interesting real-world example that gives rise to the specific research question of interest.

Students are then presented with a general idea of how to tackle this problem along with some intuitive and straightforward approaches.

Finally, a number of representative algorithms are introduced along with concrete examples that show how they function in practice.

While theoretical analysis sometimes overcomplicates things for students, here it’s applied to help them better understand the key features of the techniques.

Finite Element Method (FEM) is a powerful tool. FEM is an effective numerical technique for partial differential equations (PDEs) in engineering. The fact that modern engineers can obtain detailed information for structural, thermal, electromagnetic problems with virtual experiments largely gives credit to FEM. The finite element method provides infinite possibilities for engineering, and this course provides a detailed introduction of FEM and its applications in engineering and beyond.

This course is divided into 15 lessons, which introduce basic equations of mechanics, mathematical principles of FEM, realizations in both discrete and continuum structures, various applications in engineering and skills at modeling with FEM software. Examples are demonstrated with MATLAB and ANSYS.

有限元方法(finite element method)：基于数学力学原理，采用计算机信息化分析手段，完整获取复杂工程问题及科学研究中的定量化结果，也被称为一种基于计算机信息化处理的“虚拟实验”，在数学上它是求取复杂微分方程近似解的有效工具，是现代仿真技术的重要基础原理。有限元分析的力学基础是弹性力学，方程求解的数学原理是加权残值法和泛函极值原理，实现的方法是数值化离散技术，最终的载体是有限元分析软件。有限元方法已成为机械、航空航天、土木、力学等专业学生的必备知识。

这门课程的主要内容包括：基本变量和力学方程、数学求解原理、离散结构和连续体的有限元分析实现、各种应用领域、有限元分析的软件平台和建模技巧等。在强调有限元理论的工程背景和物理概念的同时，通过一些典型的实例来深入浅出地系统阐述有限元分析的基本原理。此外，课程基于MATLAB演示基于有限元原理的编程方法，通过ANSYS来展示应用有限元方法的具体建模过程。

In this physics course you will learn about electromagnetism, a branch of physics, which includes the study of electric and magnetic fields.

This is a seven-week course, broken up into both basic and advanced sections. Most learners and engineering students may choose to study only the basics. Those who want to learn at the level of a physics major should study the advanced sections of the course as well. However, the final examination will only cover the basic parts.

本电磁学课程主要学习电场和磁场，一般需要28学时 (7周左右)。视频分为基本内容和提高内容（打星或双星），普通学习者和工科学生只需选择基本内容学习，要达到物理专业的学习要求，则需要额外学习提高内容。最后考试只覆盖基本内容。

Geometry can be traced back to ancient Greece, but Computational Geometry evolved less than 40 years as a branch of computer science. The Computational Geometry taught in this course is derived from classical discrete/combinatorial geometry and modern computer science.

Computational Geometry first appeared on the horizon when M. I. Shamos presented his Ph.D. dissertation in 1978. Since then, this phrase has been used to refer to algorithmic study on discrete and combinatorial geometric structures and can also be regarded as the geometric version of Algorithm Design and Analysis. Computational Geometry is now considered the basis of robotics, computer aided design and manufacturing (CAM and CID), and geographic information systems (GIS).

众所周知，几何学的历史至少可追述至古希腊时代，但不同人对“计算几何”的理解却不尽相同。本课程讨论的计算几何，源自于古典离散/组合几何学与现代计算机科学的结合。M. I. Shamos在1978年完成的博士论文，标志着这个学科分支的诞生。从那时起，“计算几何”往往特指针对离散与组合几何结构的算法研究。简而言之，她也可认为是算法设计与分析的几何版。

本课程的教学目标有三：

其一、对计算几何理论的总体认识，在日后的研究工作中，这种认识为你提供几何的视角
其次、对几何问题求解范式及策略的全面领会，包括递增式构造、平面扫描、分而治之、分层化、近似以及随机化等
最后、对基本几何结构及其算法的透彻掌握，包括凸包、多边形细分、Voronoi图、Delaunay三角剖分，以及几何求交、点定位、范围查找、截窗查询等
