Have you ever wondered how information is transmitted using your mobile phone or a WiFi hotspot? Gain an understanding of the basic engineering tools used and tradeoffs encountered in the design of these communication systems.  

This course is divided into three parts. In Part 1, we examine the point-to-point link, which communicates information from a single transmitter to a single receiver. Part 2 examines how multiple transmitters can share the same physical channel. Part 3 discusses how information can be transmitted reliably from one station to another over a network that connects multiple stations. Online interactive exercises are included to help build your intuition.

This course was inspired by and built upon the course 6.02 Digital Communication Systems developed at MIT, which Prof Bertram Shi worked on during his sabbatical in 2009.

Level Up! covers the complete Advanced Placement* Computer Science A course in unique and engaging ways. It's a significant change of pace from other online introductory programming courses. While you will rigorously learn the art of programming in Java, you will spend much of your time designing and writing games and simulations.  This course has no textbook because all the materials are online.  You’ll be reading; checking your understanding with self-tests; analyzing, modifying, and debugging code as well as writing it; and working with your fellow students to come to common understandings.  You’ll work with sounds and pictures (what do you sound like speaking backwards?), write adventure games and “smart” board games, and spend time trying to understand whole programs rather than just little pieces.
 
We’ve designed this course to help high-school students prepare for the Advanced Placement Computer Science test, and we’ll cover everything you need to know. It has been successfully used in classrooms for several years, and now its available for anyone, in school or not, through EdX. If you are an adult or a student who isn’t going to take the AP test, you are more than welcome to join!  We go beyond the minimum required by the AP committee, introducing graphics, mouse commands, and other tools for real programmers.
 
We based this course on the principles of “lab-centric” instruction, in which lectures are replaced by hands-on activities.  We won’t include long, fact-filled videos, and the webpages in this course will be your “textbook”.

How did Newton describe the orbits of the planets? To do this, he created calculus.  But he used a different coordinate system more appropriate for planetary motion.  We will learn to shift our perspective to do calculus with parameterized curves and polar coordinates. And then we will dive deep into exploring the infinite to gain a deeper understanding and powerful descriptions of functions.

How does a computer make accurate computations? Absolute precision does not exist in the real world, and computers cannot handle infinitesimals or infinity. Fortunately, just as we approximate numbers using the decimal system, we can approximate functions using series of much simpler functions. These approximations provide a powerful framework for scientific computing and still give highly accurate results. They allow us to solve all sorts of engineering problems based on models of our world represented in the language of calculus.

A Room with a View is a 1908 novel by English writer E.M. Forster.  

A Room with a View is a romance and a critique of English society at the beginning of the 20th century. As Forster’s most romantic and optimistic book, A Room with a View is considered one of the top 100 English language novels of all times. An award-winning film adaptation of this novel came out in 1985.

Participants in this course will read, discuss, and write about the text and its influence. As in most book clubs, the focus will be on lively discussion. Course materials will include background information for understanding the text, as well as vocabulary and language support. Assessment will include quizzes and short writing assignments.

The Beauty and Joy of Computing (BJC) is a computer science principles course developed at the University of California, Berkeley, intended to broaden participation in computing to non-traditional groups. Computing has profoundly changed the world, opening up wonderful new ways for people to connect, design, research, play, create, and express themselves. However, just using a computer is only a small part of the picture. The real transformative and empowering experience comes when one learns how to program the computer, to translate ideas into code.

This course teaches students how to do exactly that, using Snap! (based on Scratch), one of the friendliest programming languages ever invented. It's purely graphical, which means programming involves simply dragging blocks around, and building bigger blocks out of smaller blocks. But this course is far more than just learning to program. We focus on seven big ideas (creativity, abstraction, data and information, algorithms, programming, the Internet, and global impact), and six computational thinking practices (connecting computing, creating computational artifacts, abstracting, analyzing problems and artifacts, communicating, and collaborating). Throughout the course, relevance is emphasized: relevance to the student and to society. This fun, introductory course is not just for computer science majors, it’s for everyone… join us!

The Call of the Wild is a 1903 novel written by Jack London. The story is set in the Yukon, the far northern territory of Canada/Alaska, during the 1890s Klondike Gold Rush. During this period, good sled dogs were in high demand. The novel's main character is a dog named Buck, who lives on a California ranch.

London himself lived nearly a year in the Yukon, collecting material for the novel. Like many older popular novels, The Call of the Wild was serialized in the Saturday Evening Post in the summer of 1903. A month later, it was released as a  book. The novel’s great popularity and success made London famous. The appeal of this story comes from its simplicity as a tale of survival. As early as 1908, the story was adapted to film. Since then, there have been other adaptations.

Participants in this course will read, discuss, and write about the text and its influence. As in most book clubs, the focus will be on lively discussion. Course materials will include background information for understanding the text, as well as vocabulary and language support. Assessment will include quizzes and short writing assignments.

This course will examine Oscar Wilde’s only novel, The Picture of Dorian Gray. This novel was first published as a serial novel in Lippincott’s Monthly Magazine in 1890.

The Picture of Dorian Gray was immediately controversial, and was censored by the magazine’s editors. Even with the censorship, reviewers still thought that Wilde ought to have been prosecuted for violating laws concerning public morality. This story has two important themes: the idea of selling one’s soul, and the theme of living a double life. Wilde takes these themes to their extreme.

SCOPE: To create an interactive learning module to help reinforce the concept of maintaining lab safety where hazardous materials are used in various laboratories.

Academic laboratories where hazardous materials are used are potentially dangerous places. Taking the necessary precautions to avoid unnecessary hazards is paramount for the safety of all involved.

In this course, you will learn about lab safety through an interactive game called "Don't Endanger the Owls".

The characters in the game include Wise Owl, Owlet, and the Zombie Squirrels. Owlet is the student figure and Wise Owl is Owlet’s sage advisor / professor figure.

In the game, your goal is to stop the Zombie Squirrels from spreading their Zombiegen by finding an “Anti-Zombiegen” in the lab that will counteract the effects of the Zombiegen. In order to find the Anti-Zombiegen, you will journey through three lab rooms: the biology lab, the chemistry lab and the analytical lab. Along the way, you will learn safe laboratory practices. In the end, if you follows safe laboratory practices, you will find the Anti-Zombiegen and saves the campus from the Zombiegen outbreak.

“Don’t Endanger the Owls” is a collaboration between the instructors of Rice University’s Responsible Conduct of Research Graduate Course, Rice’s Environmental Health and Safety and HyperWindows Inc.

The course is suitable for students seeking eventual employment with a brokerage company, investment company or financial services company with responsibilities in evaluating and selecting equity securities for investment portfolios.

Brain and behavior are inextricably linked in neuroscience. The function of the brain is to govern behavior, and the aim of this course is to causally link biophysical mechanisms with simple behaviors studied in mice. The brain processes information through the concerted activity of many neurons, which communicate with each other through synapses organised in highly dynamic networks. The first goal of the course is to gain a detailed understanding of the structure and function of the fundamental building blocks of the mammalian brain, its synapses and neurons. The second goal is to understand neuronal networks, with specific emphasis on the interactions of excitatory glutamatergic and inhibitory GABAergic neurons. The third goal is to place neuronal network function in the context of sensory processing ultimately leading to behavioral decisions and motor output.

Le cours met l'accent sur le lien entre les prédictions théoriques et les observations et constitue la base indispensable des cours d'astrophysique avancés.

Quantitative Methods in Clinical and Public Health Research is the online adaptation of material from the Harvard T.H. Chan School of Public Health's classes in epidemiology and biostatistics. Principled investigations to monitor and thus improve the health of individuals are firmly based on a sound understanding of modern quantitative methods. This involves the ability to discover patterns and extract knowledge from health data on a sample of individuals and then to infer, with measured uncertainty, the unobserved population characteristics. This course will address this need by covering the principles of biostatistics and epidemiology used for public health and clinical research. These include outcomes measurement, measures of associations between outcomes and their determinants, study design options, bias and confounding, probability and diagnostic tests, confidence intervals and hypothesis testing, power and sample size determinations, life tables and survival methods, regression methods (both, linear and logistic), and sample survey techniques. Students will analyze sample data sets to acquire knowledge of appropriate computer software. By the end of the course the successful student should have attained a sound understanding of these methods and a solid foundation for further study.

Addressing students' interests in 20th century Western Music Culture and incorporating music theory, the course examines 20th century Western music. By combining theory and practice, the course not only aims to provide a clear view of the historical development of the music, but also emphasizes the training of aural skills and the accumulation of musical knowledge. The course covers not only classical music, such as neo-classical, expressionism, nationalism and other genres, but also explores in depth jazz, rock, and pop music of the 20th century. While studying Chinese music and other forms of national folk music in the 20th century world music context, students will also analyze large and complex works such as opera, musicals, and film music. By enhancing students’ understanding of 20th century Western music (classical music, pop music, folk music, comprehensive art) as a foundation, three core questions will be addressed: what is music, what is the 20th century Western music, and what is effective listening? The course aims to guide students to examine the three listening modes of 20th century Western music with the hope of forming a diverse and multi-faceted, knowledge and understanding of the 20th-century Western music culture phenomena, expanding students’ horizons, enhancing their ability to reason by analogy, and promoting cross-disciplinary, creative development.

课程重视知识还是能力？
课 程最关心音乐聆听能力的发展，在提供行之有效聆听技术的同时，安排适当知识内容的传授。加之考试不重知识，而重能力，因此，课程中因教室光线不足而造成无 法做太多笔记，恰恰是教师所希望的。课后传发同学的曲目说明，其中所标出的知识点，所指系能力而非知识。在音乐领域，所谓历史是听觉样本，即艺术品本身积 累起来的，而非人名和作品名串联起来的。艺术史，是感觉的历史，不是文字描述的历史。

What is the aim of the music puzzle assignment within the course?

The purpose of the assignment is to prepare and develop audiometry and memory skills.

课程所谓音乐拼图作业的目的是什么？
作 业的目的，在于听觉甄别力和记忆力的筹备与发展。相当于我们小时候玩得拼图或积木游戏，从局部观察到整体把握，这一训练所形成的对线条、形状、色泽等构成 物的甄别与记忆，不仅是视觉所需，也是发达听觉所必备。多数情况下，类似课程作业的练习，在中国音乐课程中，很少会有。之所以课程一开始便这样做，是因为 知道学生听觉的普遍问题。不少同学在实践之初，会遇到困难，这很正常，如果没有做好接受困难的准备，也就不必来此课程分享，也就不必来北大读书了。

Will the course provide information about music composition and technology?

No. Music composition mastery requires long-term training, usually at a conservatory level.

课程是否可能或可以提供关于作曲的知识与技术？
课 程不可能在作曲方面给予单独帮助，通过目前的教学方式，尽管正在探索，教师只能也必须照顾到最大多数同学的需求，这一难处，是客观的，请多谅解。关于作曲 四大件的技术发展，在音乐学院有一套完整的训练程序，乐理是入门，和声是基础，二者建立关于调性音乐系统的初阶。随后的复调写作，作曲系耗时约需一年甚至 更多，根据全面仿作练习，帮助同学发展多声思维和多声部操控技术。配器是第三梯度，约需一年时间完成，全面掌握乐队法。曲式分析，是封顶收官之课。将之前 所有梯队课程的内容，一并总结。

Will the course be available in English?

The videos in the course will include English subtitles. However, the rest of the course content will only be available in Mandarin.

这门课程使用英语授课吗？
视频中教师使用中文授课，有英文字幕，但是课程的其他内容，如阅读、作业题、讨论等都只用中文。
