Matrix Algebra underlies many of the current tools for experimental design and the analysis of high-dimensional data. In this introductory data analysis course, we will use matrix algebra to represent the linear models that commonly used to model differences between experimental units. We perform statistical inference on these differences. Throughout the course we will use the R programming language.

Given the diversity in educational background of our students we have divided the series into seven parts. You can take the entire series or individual courses that interest you. If you are a statistician you should consider skipping the first two or three courses, similarly, if you are biologists you should consider skipping some of the introductory biology lectures. Note that the statistics and programming aspects of the class ramp up in difficulty relatively quickly across the first three courses. By the third course will be teaching advanced statistical concepts such as hierarchical models and by the fourth advanced software engineering skills, such as parallel computing and reproducible research concepts.

These courses make up 2 XSeries and are self-paced:

PH525.1x: Statistics and R for the Life Sciences

PH525.2x: Introduction to Linear Models and Matrix Algebra

PH525.3x: Statistical Inference and Modeling for High-throughput Experiments

PH525.4x: High-Dimensional Data Analysis

PH525.5x: Introduction to Bioconductor: annotation and analysis of genomes and genomic assays 

PH525.6x: High-performance computing for reproducible genomics

PH525.7x: Case studies in functional genomics

In this hands-on course, you’ll learn how to perform engineering simulations using a powerful tool from ANSYS, Inc. This is a problem-based course where you’ll learn by doing. The focus will be on understanding what’s under the blackbox so as to move beyond garbage-in, garbage-out. You’ll practice using a common solution approach to problems involving different physics: structural mechanics, fluid dynamics and heat transfer.

We’ll solve textbook examples to understand the fundamental principles of finite-element analysis and computational fluid dynamics. Then we’ll apply these principles to simulate real-world examples in the tool including a bolted rocket assembly and a wind turbine rotor.We’ll discuss current industry practices with a SpaceX engineer. By working through examples in a leading simulation tool that professionals use, you’ll learn to move beyond button pushing and start thinking like an expert.

This course teaches fundamental concepts and tool use in an integrated fashion using the power of online learning. All learners will have access to a free download of ANSYS Student.

Join us to discover why simulations have changed how engineering is done and how you can be a part of this revolution.

In Part 2 of Science and Cooking (Part 1 is available here), we will be visited by more world-famous chefs who use a number of different styles and techniques in their cooking.  Each chef will demonstrate how he or she prepares delicious and interesting creations, and we will explore how fundamental scientific principles make them possible.

Topics will include:

• How cooking changes food texture
• Making emulsions and foams
• Phase changes in cooking

You will also have the opportunity to become an experimental scientist in your very own laboratory — your kitchen! By following along with the recipes of the week, taking precise measurements, and making skillful observations, you will learn to think like both a chef and a scientist.  This practice will prepare you for the final project, when you will design and perform an experiment to analyze a recipe of your choice from a scientific perspective.

The lab is certainly one of the most unique components of this course — after all, in what other science course can you eat your experiments?

This course focuses on the physical changes that occur during cooking.  If you are interested in signing up for “Part 1,” which focuses more on the chemistry of cooking, you can do so here.

Christianity is a global religion. From modest beginnings 2,000 years ago, it has grown to encompass nearly a third of the human population. Diverse in languages, cultures, histories and creeds, Christians nonetheless share a common collection of sacred scripture called the Bible.

This religion course introduces you to the Bible and its scripture and asks the questions:

• What are the contents, languages, and forms of Bibles in various times and places?
• How have Christians lived out their stories and teachings?
• How does Christian history reflect the contested and varied uses of scripture—in the ancient Roman world where Christianity began, in its spread through European and American colonialism, in the diverse forms it takes in varied locations around the globe?

You will begin to explore these questions and others while learning about the content and interpretations of these sacred texts.

No previous knowledge of Christianity or the Bible required.

Imagine that you are a bank and a main part of your daily business is to lend money. Unfortunately, lending money is a risky business - there is no 100% guarantee that you will get all your money back. If the borrower defaults, you will face losses in your portfolio. Or, in a bit less extreme scenario, if the credit quality of your counterparty deteriorates according to some rating system, the loan will become more risky. These are typical situations in which credit risk manifests itself.

According to the Basel Accord, a global regulation framework for financial institutions, credit risk is one of the three fundamental risks a bank or any other regulated financial institution has to face when operating in the markets (the two other risks being market risk and operational risk). As the 2008 financial crisis has shown us, a correct understanding of credit risk and the ability to manage it are fundamental in today’s world.

This course offers you an introduction to credit risk modelling and hedging. We will approach credit risk from the point of view of banks, but most of the tools and models we will overview can be beneficial at the corporate level as well.

At the end of the course, you will be able to understand and correctly use the basic tools of credit risk management, both from a theoretical and, most of all, a practical point of view. This will be a quite unconventional course. For each methodology, we will analyse its strengths as well as its weaknesses. We will do this in a rigorous way, but also with fun: there is no need to be boring.

Thanks to the wonderful feedback of last year’s students, the course has been further improved.

When you meet a new person, it is hard to know what to expect.  You may not be able to read the person or understand what they mean. Even if you want to have a good relationship with them, this lack of understanding can make interactions tense, unpredictable and scary! The same is true for a lot of people as they encounter statistics and mathematical ways of working with data.  Statistics can be confusing and opaque.  Symbols, Greek letters, very large and very small numbers, and how to interpret all of this can leave to feeling cold and disengaged—even fearful and resentful.

But in the modern information age, having a healthy relationship with statistics can make life a whole lot easier. We are constantly faced with an onslaught of data and claims about it—from news articles, to Facebook and blog posts, casual and professional conversations, reports at our workplace, advertising, and claims from politicians and public officials. How can we process that information, make sense of it, evaluate truth claims, and put ourselves in a position to act on the information?  One of the most important ways is by befriending statistics and consistently using statistical ways of thinking.
 
The purpose of this course, then is to help you develop a functional, satisfying, and useful life-long relationship with statistics. To achieve that goal, we will take a non-technical approach—you will learn how statistics work and why they are so helpful in evaluating the world of information that is around us. You will learn about the logic of statistical thinking and the concepts (rather than the mathematical details and probability theory) that guide statistical inferences and conclusions.
 
You do not need to be a math whiz to take this course. If you can add, subtract, multiply, and divide (or just be able to use a calculator to do that!), you will be more than able to handle what will happen as this relationship develops.

By the end of the course you will be able to:

• Identify the most important features of a data set
• Select a statistical test based on the features of the data
• Think like a statistical detective
• Understand the relationship between two different characteristics or variables
• Perform some simple statistical calculations and draw some conclusions from real data
• Hopefully, love stats! 

We’ll do all of this using entertaining examples related to real-life situations we all encounter in everyday life.

You face a difficult moral decision every time you decide what to eat. What impact should animal rights have on your decision? Is the suffering involved in meat, egg and dairy production bad enough that you should go vegan? How do your food choices affect the economy and the environment? Should you become a locavore? Should you eat only sustainably produced, "farm to table" food? Or is factory-farmed food more efficient and ultimately better for the environment?

We also face difficult food-related questions at the political-social level. Should states restrict their citizens' food choices so as to encourage healthy eating? Should governments grant patents on genetically modified crops? And how do we, as a society, implement effective food policies for a rapidly expanding world population?

This class will provide the tools required to reflect clearly and effectively on these challenging questions.

Our goal is to provide a working understanding of some leading ethical theories as well as the central empirical issues related to food production, distribution and consumption. Along the way, students will hear from a variety of scientists, philosophers, activists, and industry participants:

• Carol Adams, author of The Sexual Politics of Meat
• T. Colin Campbell, Cornell nutritionist and author of The China Study
• Mark Bittman, cookbook author and New York Times food writer
• Marion Nestle, nutritionist and author of Food Politics
• Joe Regenstein, Cornell food scientist and director of the Kosher-Halal Food Initiative
• Joel Salatin, alternative farming advocate and author of 9 books
• Bryant Terry, award-winning chef, author of Vegan Soul Kitchen
• Brian Wansink, Cornell food and brand psychologist, author of Mindless Eating
   

We are in the midst of an explosion of musical creativity as a result of technologies that allow you to record music using your laptop or tablet. Whether you are a singer, music producer, audio engineer, or just someone that likes to make good music with vocals, it is essential to have an understanding of vocal technologies for music production.

This music production course provides learners with insight into the voice itself, the recording environment, microphones, equalization, compressors, A-D-A conversion, the listening environment, human perception, natural widening concepts, artificial widening concepts, reverb, delay, and more. Grammy-award winning record producer, audio engineer, recording artist, and educator Prince Charles Alexander offers students a first-hand opportunity to learn the technologies behind vocal production, so that you can enhance your music productions with the most compelling and effective vocal tracks.

Three things are clear about today’s music industry: The consumption of music is expanding at the greatest rate in history and from the most portals ever imagined, the cost of producing music is decreasing, and the number of artists creating and seeking to expose their work and develop careers through the Internet has increased dramatically. As demand grows and Internet piracy wanes, ad-supported and subscription models will generate unprecedented revenues that will surpass even the best of past earnings. And, many astute “music industry-watchers” predict a steep rise in business activity and trade earnings by the end of the decade.

Whether you’re a music creator, consumer, or facilitator of this process, you’ll want to understand the history, underpinnings, and basics of the music business. This course has been developed to provide students with the latest instruction on the best way for creators, consumers, and facilitators to navigate the resurgence of one of the world’s most exciting industries: the music business. Course author John Kellogg—administrator, educator, entertainment lawyer, performer, and radio and television personality—offers students the opportunity to learn the fundamental principles of the developing new music business, for now and into the future.

Is a good, solid argument enough to make an impact? How would you disprove the stance that man-made global warming is just an “opinion”? How would you explain your opinion on school tests, budget cuts, crime, immigration, safety and security issues?  No doubt that your persuasiveness relies on your arguments. But your ability to influence and convince critically depends on the way you frame your message.

In today’s world, you often need to reduce a complex reality to a concise and convincing message. Framing is an approach that deals with the way we convey our message: our words, images, and metaphors. To take one basic characteristic, a good frame engages the listeners’ values and emotions – it is easy to remember and it is something that people will usually agree with intuitively.

When you enter into a debate, you might be faced with frames of your opponents – and you will have to reframe the debate. This game of framing and reframing makes the debate to look like a chessboard made out of words. Of course, politicians play this game, trying to pull the debate towards their own words and metaphors in order to win their audience. But the game can be found everywhere: in the world of business, science, media – even at home.

We invite you to join our journey of learning the game of framing and reframing. You will discover how this game is played, and how you can play it yourself. 

This course suits people who are engaged with and interested in public and political debates. Not only people from the public sector will find it useful, but also engineers, consultants, managers and anyone who wants to make an impact in discussions and debates.

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
