Computer Science and Technology


Harvard University - CS50X: Introduction to Computer Science - Professor David J. Malan - One of our favorite computer science courses, Harvard's excellent Introduction to Computer Science, CS50x, is starting a new term this month, and if you're at all interested in learning to code, now's the time to sign up. When freshmen arrive at Harvard looking to study Computer Science, this is the course they land in first, and you can take it online with them. In this class you'll learn the basics of computer science, learn to code from the ground up, and study languages like C, PHP, and JavaScript plus SQL, CSS, and HTML. You'll solve real problems in biology, cryptography, finance, forensics, and gaming. It's demanding, but it's an amazing course. Plus, you can earn a certificate from Harvard for successfully completing it. Supplimental material is available at CS50.net. Udacity - Mobile Web Development - Professors Chris Wilson and Peter Lubbers - Developing for the mobile web isn't easy, and it's not just because of smaller screens. You have to consider touch as a primary interface for your site or application, variable screen sizes, users using your service in desktop mode on a mobile device, and more. This course—one we've mentioned before but is still one of our favorite classes for mobile web development—will teach you how to build mobile web experiences that enrich your users and visitors, and even use open APIs available for mobile devices, like geolocation, accelerometer access, and more. You'll also learn how to evaluate mobile performance, so you can make sure your apps and tools work even when network access is spotty. University of Reading Begin Programming: Build Your First Mobile Game - Professor Karsten Ă˜ster Lundqvist - If you're eager to code because you want to build mobile games or start a business building mobile apps, this course can get you started building Java-based mobile games. The aim of the class is, of course, to give you an introduction to programming, specifically in Java, using mobile games and gaming as a hook, and it's beginner-friendly at that. No specific knowledge of programming is required to get started, and this seven week course (starting near the end of January) will have you building and playing mobile games before it's all over and done. University of Maryland - Programming Mobile Applications for Android Handheld Systems - Professor Adam Porter - If you're looking for a more rounded approach to building a mobile app for Android, this course (from my alma mater!) will have you up and running in no time. You don't have to have an Android device to participate (you can use an emulator), but the full syllabus for the course is already posted, and it'll walk you through the basics of the Android platform, resources available to Android developers, application design and frameworks, graphics and animation, using device sensors, and more. Stanford University - Networking: Introduction to Computer Networking - Professors Philip Levis and Nick McKeown - If network administration or engineering is more your interest (as opposed to software development and coding), then this course will teach you the basics of connected information networks, most notably the largest one on the planet: the Internet. You'll learn everything from the ground up, including how popular technologies like BitTorrent and HTTP work, but you'll also study the basics of network design and protocols. You'll read RFCs, study them, and then discuss them with classmates, and the course even touches on current events and internet issues like net neutrality, DNS security, and wiretapping. University of Michigan - Internet History, Technology, and Security - Professor Charles Severance - There are still a lot of us who remember the early days of the internet, when the public was just becoming aware of this vast resource of information available at our fingertips. However, the history of the internet extends far past when consumers and the public got on board, and new users or today's beginners may have no idea how the internet was born, what it was originally designed to do, and the technology that powered (and in some cases, still powers) it. This course will give you a primer to all of those topics and more, including current events and topics of identity, personalization, data collection, individual and corporate security, and more. By the end of the course, the professor explains, you won't take the internet for granted. University of Oklahoma - Power and Elegance of Computational Thinking - Professor Amy McGovern, PhD - If you have absolutely no programming experience (and aren't interested in learning to code) but you're still interested in how computers work and how systems "think," this course will help you understand computational thinking, start thinking that way yourself, and apply basic computational principles in real-world exercises. By the end of the course, you may very well be more interested in computer science. University of Southampton - Web Science: How the Web is Changing the World - Professors Leslie Carr and Susan Halford - The web is very different from the Internet, although the two have largely become mingled because so many people live on the web. There's more to the picture, but the web—the World Wide Web, precisely—shouldn't be discounted in the way it's changed the way we live our lives. Everything from the way we shop, the way we plan major life events like weddings, vacations, jobs, and moves, and the way we entertain ourselves have all changed drastically thanks to the web, and in this course you'll examine the history of the web, the technology that drives and powers it, and learn about the people who made it what it is today. You'll also study key questions of democracy and freedom when it comes to the web versus information control, networking principles, the economics of the web, and of course, how you can get in.

Finance and Economics


University of California, Irvine - The Power of Macroeconomics: Economic Principles in the Real World - Professors Peter Navarro and Ali Saffari - Macroeconomics, or the branch of economics that has to do with large scale economies and financial systems as a whole, can be pretty difficult to understand and get your arms around. That doesn't stop many people from positing on what economies should and shouldn't do, or what is or isn't in the best interest of businesses, nations, and peoples. This course will give you the information required to really understand the economics of nations, businesses, and international systems so you can be a more informed consumer of news and public policy. You'll learn about popular theories and economists who shaped today's approach to finance, and cover topics like unemployment, inflation, deflation, monetary policy, budget deficits and public debt, and more. Best of all, the course is aimed at people with no economics background. University of California, Irvine - The Power of Microeconomics: Economic Principles in the Real World - Professors Peter Navarro and Ali Saffari - By contrast to macroeconomics, microeconomics has to do with smaller organizations, individual households and businesses, and smaller movements of money. In this course, you'll pick up the basics of supply and demand, consumer behavior and marketing, monopolies and competition, oligopolies, strategic behavior of businesses, the labor market, even land and rent. You may not be balancing your checkbook in this course, but you will understand how businesses do it, and what it really means when you call someone a monopoly—and how it compares to the monopolies of the past, whether it's more or less similar than you expected. IE Business School - Understanding Economic Policymaking - Professor Gayle Allard -The decisions and movements of money by large governments and public organizations can be confusing to say the least, and it's easier to rise up in outrage than to stop and consider why the money moves where it does and who actually benefits from it. This course is designed to help you understand those processes, how the media uses financial information to inform the public, and what terms like GDP and inflation really mean on a global scale. You'll study the current and ongoing international financial crisis and how governments around the globe are responding, along with the success (or lack thereof) many of them are seeing in response to their policies. Before the end of the course, you'll try your hand at policymaking for a hypothetical nation, and see how your own philosophies and decisions pan out for the people of your fictional nation. University of East Angila - The Secret Power of Brands - Professor Robert Jones - From Apple and Samsung to Google and Microsoft to McDonalds and Taco Bell, brands have huge marketing power and mind share. Merely uttering the name of a company inspires imagery and specific messages in consumers' heads inspired either by their own marketing efforts or by their competition, and competing brands don't just drive incredible sales, but fierce competition among champions of those brands who aren't even employed by the companies that own them. This course examines the power of brands and branding, why brands matter so much and how they have such incredible sway over people—even when those people say that branding and marketing doesn't matter to them. You'll learn directly from marketing experts at companies like Google and Virgin, and open up topics of branding and marketing that are still controversial and under research. University of California, Irvine - Fundamentals of Financial Planning - Finance and economics are all well and good when they're on a large scale and have nothing to do with your household, but what about your personal finances? This self-led, anytime financial planning course is designed to help you walk through the basics like budgeting and balancing your own books all the way up to investments, estate planning, insurance, and retirement. The course covers topics that a professional financial planner would discuss with you, and by the time you've worked your way through its 22 modules, you'll ideally have a strong handle on your personal finances—and be a better consumer of financial information and services from others.

Science and Medicine


University of Virginia - How Things Work I - Professor Louis A Bloomfield - Physics is all around us; from the cars we drive to the computers we use, and this course, designed explicitly for people with no science background, aims to show you the physics behind how the world works. The course takes examples from the world around us and uses them to showcase physics in action, from how levers work, wheels roll, ice skaters glide across the ice, and so on. The class is case study driven, so while there's a little bit of math involved, it's nothing you'll need to study up for. The goal is to get people thinking about science and understanding the role that physics plays in... well, everything. The University of Edinburgh - The Discovery of the Higgs Boson - Professor Luigi Del Debbio - The discovery of the Higgs Boson was a huge milestone for physics, and it verified a lot about our understanding of the universe, how particles obtain mass, and went a long way towards completing the Standard Model of particle physics. If all of that means nothing to you, but you did hear about the Higgs when it was discovered, that's because it was also one of the most covered and publicized scientific events in recent memory, even earning Peter Higgs, the man for which the particle is named, a Nobel Prize. So how did it happen? What is the Higgs Boson, and what does it mean that we discovered it? This course will tell you, and help you explore the purpose and design of the Large Hadron Collider (LHC) which was so instrumental in its discovery. The University of Southampton - Exploring Our Oceans - Professors Jon Copley and Verity Nye - More than half of the Earth's surface is covered by water, and while we largely have them mapped, so little of it has actually been explored that it's remarkable. The depths of the oceans still harbor amazing creatures, formations, and ongoing processes that clue us in to how the Earth was formed, how everything we know got here, and what the Earth will look like thousands or millions of years from now. This course will show you some of those mind-blowing sights and stories, from the icy depths of the poles to the tropical trenches near the equator. University of Bath - Inside Cancer: How Genes Influence Cancer Development - Dr Momna Hejmadi - If you've ever heard that someone in your family had a certain type of cancer and it made you worried, or that a direct relative of yours died of cancer, you undoubtedly started wondering and researching about whether their type of cancer is hereditary or influenced by genetics. This course explains how genes and genetic expression can influence cancer, how genes can make people more or less likely to develop cancer, and the fundamental differences between cancer cells and regular cells. Essentially how cancer forms, how it differs from normal cells in our bodies, and what makes some people more or less likely to develop it. Duke University - Introduction to Astronomy - Professor Ronen Plesser - Without a doubt, you've looked up at the starry night sky and wondered what was out there, what you were looking at exactly, how far away from us it was, and what it looked like close up. This introduction to Astronomy course will help you understand not just what it was you were looking at, but the processes and mechanisms that describe how the stars and planets came to be, how they move around the sky, what they look like near and far, and more. You'll start with basic, naked-eye astronomy and progress from near-earth out to the far reaches of the galaxy, learning more about everything you pass along the way, and then beyond to quasars, supernovae, and the universe as a whole, exploring what we know about it and, more interestingly, what we don't know. Australian National University - The Greatest Unsolved Mysteries of the Universe - Professors Brian Schmidt, PhD and Paul Francis, PhD - If you've ever wanted to sit in the tutelage of a Nobel Prize winner, now's your chance. This course from the Australian National University is led by Brian Schmidt, 2011 Nobel Prize winner in Physics and one of the people responsible for the discovery of dark energy—the mysterious inflationary force that's causing our universe to continually expand at an ever-increasing rate. What is dark energy? Why is the universe still expanding? How do we detect dark energy? These are all contemporary questions in modern astronomy and cosmology, and while there may not be specific answers, there are plenty of theories. Join Schmidt and Francis in exploring some of the greatest mysteries of the Universe in this course—things that, for all we know and understand, we still don't have the data or technology to puzzle out just yet. University of Birmingham - Good Brain, Bad Brain - Professor Alison Cooper - We know a lot about the brain and how it works, but a detailed map of it and what every part of the brain does still eludes us. For as much as we understand about neurology and neuroscience, there's just as much that's not clear to us, or has conflicting reports and studies over the years. This course will guide you into the topic of neurological science, help you get your bearings around how the brain works, what—beyond our thoughts and feelings—it's capable of doing, what we know, and what we're trying to figure out. Designed for the non-technical or non-medical person, by the end of the class you'll have a whole new appreciation for your own brain, and how it works diligently around the clock to keep you alive, inspired, functioning, and healthy. University of Alberta - Dino 101: Dinosaur Paleobiology - Professors Philip John Currie and Victoria Megan Arbour - A lot has changed in the field of paleontology since you were a child, and that's comfortable to say without knowing what age you may be. Dinosaur physiology used to be extremely poorly understood, but even today, thanks to DNA sequencing, better imaging tools and technologies, and never-before seen samples and fossils, we know more about dinosaur biology than ever before. In this course, you'll learn about the myriad dinosaur species that roamed the earth in the Mesozoic Era, from 250 to 65 million years ago. You'll study how dinosaur species evolved and adapted to their changing world, developing new techniques to attack and defend themselves, run, jump, swim, and fly, find mates, settle down, and, of course, what brought the age of the dinosaurs to an end and what that end probably looked like. University of Exeter - Climate Change: Challenges and Solutions - Professor Tim Lenton - This course aims to take the topic of climate change, set it against the natural climate variations of the past, and examine—with real data—the causes and influences of the global climate shifts of the past several hundred years. It's a multidisciplinary course with a heavy focus on provable science, and incorporates experts from multiple fields to discuss the data at hand, the impacts of climate change, and what can be done to avert, remedy, or correct for those effects. Stanford University - EP101: Your Body in the World: Adapting to Your Next Big Adventure - Professor Anne L. Friedlander, PhD - If you wanted to climb a mountain, base jump, or dive into the deepest parts of the ocean, would you be physically ready? You may be in good shape (or maybe not), but drastic things happen to our bodies when we put them in amazing situations. This course will help you prepare for your next big adventure, and rather than just teach you lessons, you'll hear from experts, doctors, and adventurers, watch them as they do what they do best, and see real videos of amazing things that only humans can do. You'll learn how the body responds to cold, heat, stress, altitude, pressure, even how the aging process works, and more, in a truly exhilarating environment. University of Oklahoma - Chemistry of Beer - Professor Mark Morvant, PhD - Beer is delicious, and can even be nutritious, since it's fortified with minerals and vitamins that your body actually needs. In this course, you'll understand the chemistry that's not just going on in your bottle or glass of beer, but the chemistry behind how beer is made, how beer was made in the past, and the differences between styles and types of beer. You may want to have some knowledge of general or organic chemistry for this course to make the most of it, but since it's free (and not for credit unless you're a UO student), you might be able to squeak past on an otherwise incredibly interesting topic.

Mathematics


Stanford University - Introduction to Mathematical Thinking - Professor Keith Devlin - Mathematical thinking isn't the same as actually doing mathematics, as Devlin will describe. The goal of this course is to teach you to think mathematically and analytically—to think logically about a problem or puzzle and try to deduce the best approach based on the information available. The course starts at the beginning of February and comes in two flavors, the Extended version that's designed for college students interested in studying mathematics, and the shorter Basic version for people who just want to improve their critical and analytical thinking skills and apply what they've learned to their general and professional lives. MIT - Dynamics - Professors David Gossard, Thomas Peacock, and J. Kim Vandiver - If you land at MIT interested in studying mechanical engineering, you first have to work your way through some of the basic mathematics that explains and describes how mechanical systems work. This course will help you do just that, and has the same rigor as the MIT class for undergraduates—you'll learn about the geometry of objects in motion, you'll learn to predict the movements of objects accurately, use tools like MATLAB to perform your calculations, and understand topics like torque and angular momentum—things you see every day, but may not be able to describe. You'll definitely be able to by the end of this course. Udacity/San Jose State University - Visualizing Algebra - Professor Sandra DeSousa - Algebra can be a tricky topic, and this course will help you tackle and master it visually, with real world examples, puzzles to solve, and visual exercises for those of us who like to put our eyes on a problem instead of work in the abstract. The course is designed for people with no math background really. By the end of the course, you'll have a better feel for algebra and mathematics in general, and you'll be ready to tackle more complicated topics. Even if you're not, you'll find yourself more prepared to tackle other logical problems and analyzing patterns. The Ohio State University - Calculus One - Professors Bart Snapp and Jim Fowler - If you've mastered algebra and you're eager for more of a challenge, or you want to embrace some of the mathematics that some of your favorite scientific topics are steeped in, this course is for you. You'll need some understanding of algebra to succeed in it, but beyond that, they'll take you through the basics of derivatives, integrals, functions and limits, and more. The course is designed as a first and easygoing introduction to calculus for people who haven't approached the topic before.

Social Sciences, Classics, and Humanities


Yale University - Moralities of Everyday Life - Professor Paul Bloom - If you've ever wondered how human beings are capable of such amazing acts of brilliance, beauty, and achievement, but simultaneously capable of unspeakable cruelty and devastation, this is the class for you. The course talks about morals and ethics and how to make sense of varying opinions on topics of torture, war, genocide, racism, abortion, and more. The course aims to teach you to challenge your own biases and teach you to look at your own deeply held beliefs, but also how to challenge others, understand them, and explore the modern science of moral belief and moral action. You'll study actions from households to the battlefield, study laboratory research and real world situations, and investigate the differences between beliefs on opposite ends of every political and ideological spectrum. It's not for the easily offended or puritanical though—you'll cover topics of prejudice and bigotry, sexuality and purity, crime and punishment, vengeance and revenge, and more. University of Birmingham - Shakespeare's Hamlet: Text, Performance, and Culture - Professor Michael Dobson -Shakespeare's Hamlet is often described as one of his best works: multi-layered and intelligent, at times contradictory and paranoid, but a seminal tragedy that helps define the genre and is still performed even today. This course will walk you through the text, how the play is performed, the environment in which it was written, and so much more. You'll hear from experts in theatrical history, classic literature, and modern drama to understand how and why such a amazing piece of fiction has managed to persevere for so long. Harvard - Early Christianity: The Letters of Paul - Professor Laura Nasrallah - So much of Christianity focuses entirely on the Bible, when the Letters of Paul are some of the oldest Christian documents, written at a time when the word "Christian" didn't exist by arguably one of the first people to ever hold the title. This course examines the religious and political context of the Roman Empire two thousand years ago, what those letters said, how they were interpreted, and how their impact is still with us today. The course also examines archaeological materials and ancient documents that help shape the world in which Paul lived and wrote his letters, some of his inspirations, and what, if anything, there is to be learned from them today. University of Virginia - The Modern World: Global History Since 1760 - Professor Philip Zelikow - The world was a very different place over 300 years ago, but the underpinnings of that society are the foundations on which everything we know today are built. What did the world look like back then? What were the worries and concerns of global powers, nation-states, and of course, of everyday people? What were the amazing discoveries of the day, or the world-changing events that shaped the world then until now? This course will walk you through all of that, with special emphasis on individuals and the little histories that give us clues into what the world was like and how it came to be the way it is today. The University of Warwick - The Mind Is Flat: The Shocking Shallowness of Human Psychology- Professor Nick Chater - In many ways, human beings are incredibly predictable. We suffer under the illusion of mental depth—that all of our actions and decisions are based on some deeper, mental wrangling and inner thought processes when in reality most of our decisions, actions, and everyday activities are really defined by simple sets of needs, desires, habits, and behaviors. This course will expose some of those things to you, not to dissuade you from thinking you're an interesting person or that humans are interesting, but to help you understand the real motivations behind your own actions and decisions, and those of others, their morality, and even the movements of large markets, nations, and leaders. Rutgers University - Soul Beliefs: Causes and Consequences - Explore how the human perspective on the afterlife and the soul formed in this course. The course goes back into the depths of ancient history to explore how societies gone by all came up with and cemented their own various beliefs in a persistent "soul" that would exist after death, what those various cultures and societies believed, how those beliefs changed as time progressed, and where we stand today. The point of the course isn't to challenge anyone's specific beliefs, but rather to examine the causes and the consequences of those beliefs—how they arose, and how those beliefs then shape society, morality, ethics, and human behavior as a result. Harvard - Poetry in America: The Poetry of New England - Professor Elisa New - From Puritan poets to hip hop artists, this Harvard course aims to explore the history and variety of the past 400 years of poetry on the American continent. The course will start with the classic poets of the 17th century, retelling their lives and experiences in the New World, and progress through history all the way to the current day, where many of the themes and topics remain the same, even if the language, style, and structures have changed. You'll cover major historical figures you may know (Poe, Frost, Dickinson, etc.) but go beyond and study less well-known names and avant garde poets working on their art today. iVersity - Public Privacy: Cyber Security and Human Rights - Professor Anja Mihr - "Human Rights" is a phrase thrown around a lot, but what does it actually mean, especially in the context of the digital age and the internet? This course will examine human rights, both afforded by international law and common belief and practice, and then weave in the internet, topics of privacy, public space, e-governance, and the conflict between state sovereignty and the privacy rights of the public all in one course. It's currently going (it started last month) so hop in now to catch up!
