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

Think about your favourite wine. Imagine the brilliance of its colour in the glass, the ripe fruit aromas on the nose, a hint of toasty oak and lingering tannins on the back palate. Perhaps you like a specific wine, but can’t pinpoint the reason why. The attributes that make wine so enjoyable are achieved through the expertise of viticulturists and winemakers, whose decision-making in the vineyard and winery is underpinned by science – to be precise, viticulture and oenology.

The finer details can take years to learn, but in a matter of weeks this course will give you a broad understanding of the principles and practices used to grow grapes and make wine, and their impact on wine appearance, aroma, flavour and taste. You’ll also gain an appreciation for how cutting-edge research is helping to secure the future sustainability of the global wine industry. Whether you’re a wine novice or a seasoned oenophile,, this course is for anyone who loves wine and wine tasting. You’ll even get to make your own wine-- virtually at least!

Confidently describe wine appearance, aroma, flavour and taste.
