What exactly are genetically modified organisms (GMOs) and why do scientists develop them? Studying the science of GMOs helps us understand biotechnology’s potential role in addressing challenges in agriculture.

In this introductory Food and Nutrition course, you will learn the basics of genetic engineering, explore the political debate around the GMO and review the arguments for and against their use.

We will study the politics surrounding the GMO and its impact at both an individual level and to society as a whole; including the problems, perceptions, benefits, and risks associated with GMOs. Important to understanding the complexities around this topic we will not only be looking at the science behind how the GMO works, but also to the limitations of this science. We will also discuss the importance of information literacy as a tool for effectively identifying and evaluating issues.

Our goal is that this MOOC will impact people's understanding of science, what it can and can't do, and how information is transmitted. The intent is not to influence how people feel about GMOs, but to give them the critical thinking and scientific literacy tools necessary to make informed decisions — and to understand the broader impacts of those decisions.

学这门课需要数学基础吗?

不需要，是算法课，不是数学课。有高中数学知识足矣。

这门课的程序用什么语言编写? 学这门课是否一定要会C++?

课堂的例程都是用C++编写的，要看懂需要一定C++的知识。至于完成作业，用C, C++, Java,Pascal语言都可以。

还是不明白算法到底有什么用。会各种编程语言不就行了吗？

语言只是实现算法的工具。没有好的算法，许多问题，计算机是不能够在人可以接受的时间内计算出结果的。各大IT公司招聘时往往会考察算法，而不是只问你会哪些语言。不会算法，掌握再多种语言，也很难说是一个好的程序员。

When you notice inequality in your everyday life, do you ever wonder where it comes from, and what keeps it going?

This sociology course introduces you to core concepts of class, gender, and racial inequality, and an approach to studying complex forms of inequality called intersectionality. Featuring interviews with top scholars and discussion of the full-length award winning documentary, China Blue, which follows the life of a young seventeen-year-old worker from Sichuan province, to a Chinese jeans factory, this course will transform your perspective on yourself and others.

No previous knowledge required. Global Sociology is highly recommended.

We encounter signals and systems extensively in our day-to-day lives, from making a phone call, listening to a song, editing photos, manipulating audio files, using speech recognition softwares like Siri and Google now, to taking EEGs, ECGs and X-Ray images. Each of these involves gathering, storing, transmitting and processing information from the physical world. This course will equip you to deal with these tasks efficiently by learning the basic mathematical framework of signals and systems.

This course is divided into two parts. In this part (EE210.1x), we will explore the various properties of signals and systems, characterization of Linear Shift Invariant Systems, convolution and Fourier Transform, while the next part (EE210.2x), will deal with the Sampling theorem, Z-Transform, discrete Fourier transform and Laplace transform. Ideas introduced in this course will be useful in understanding further electrical engineering courses which deal with control systems, communication systems, power systems, digital signal processing, statistical signal analysis and digital message transmission. The concepts taught in this course are also useful to students of other disciplines like mechanical, chemical, aerospace and other branches of engineering and science.

HLS1x Copyright will explore the current law of copyright and the ongoing debates concerning how the law should be reformed.

We will explore the psychology of our everyday thinking: why people believe weird things, how we form and change our opinions, why our expectations skew our judgments, and how we can make better decisions. We’ll discuss and debate topics such as placebos, the paranormal, medicine, miracles, and more.

You will use the scientific method to evaluate claims, make sense of evidence, and understand why we so often make irrational choices. You will begin to rely on slow, effortful, deliberative, analytic, and logical thinking rather than fast, automatic, instinctive, emotional, and stereotypical thinking.

We will provide tools for how to think independently, how to be skeptical, and how to value data over personal experience. We will examine the mental shortcuts that people use and misuse, and apply this knowledge to help make better decisions, and improve critical thinking.

Organizations use their data for decision support and to build data-intensive products and services, such as recommendation, prediction, and diagnostic systems. The collection of skills required by organizations to support these functions has been grouped under the term Data Science. This course will attempt to articulate the expected output of Data Scientists and then teach students how to use PySpark (part of Apache Spark) to deliver against these expectations. The course assignments include Log Mining, Textual Entity Recognition, Collaborative Filtering exercises that teach students how to manipulate data sets using parallel processing with PySpark.

This course covers advanced undergraduate-level material. It requires a programming background and experience with Python (or the ability to learn it quickly). All exercises will use PySpark (part of Apache Spark), but previous experience with Spark or distributed computing is NOT required. Students should take this Python mini-quiz before the course and take this Python mini-course if they need to learn Python or refresh their Python knowledge.
