May 16th, 2012Top Story  Your education doesn't have to stop once you get out of school—being free of the classroom just means you have more control over what you learn and when you learn it. We've put together a curriculum of some of the best free online classes available on the web this summer for our second term of Lifehacker U, our regularly-updating guide to improving your life with free, online college-level classes. Let's get started.
Orientation: What Is Lifehacker U? Whether you're just finishing the spring semester, or you're out of school and just want to keep learning and growing, there are an incredible amount of free, university-level courses that become available on the web every school year, and anyone with a little time and a passion for self-growth can audit, read, and "enroll" in these courses for their own personal benefit. Schools like Yale University, MIT, Stanford, the University of California at Berkeley, and many more are all offering free online classes that you can audit and participate in from the comfort of your office chair, couch, or computing chair-of-choice. If you'll remember from our Spring 2012 semester, some of these classes are available year-round, but many of them are only available during the a specific term or semester, and because we're all about helping you improve your life at Lifehacker, we put together a list of courses available this summer that will inspire you, challenge you, open the door to something new, and give you the tools to improve your life. Grab your pen and paper and make sure your battery is charged—class is in session! 
Computer Science and Technology - Codecademy - Codecademy made waves by offering great free development tutorials, but saw a surge at the beginning of the year with its Learn to Code in 2012 promotion. We can't think of a better way to spend a chunk of your summer than learning a valuable skill like programming, and Codecademy is willing to teach you at your own pace, entirely for free. If you can get your friends to participate, you can even work with them, or compete with them for badges and awards.
- Stanford University - Introduction to Computer Science | Programming Methodology - Professor Mehran Sahami - If you're looking to spend some of your summer learning how to code, you'll want to pick up some of the fundamentals and theory to bolster whatever language you choose to learn. Dr. Sahami walks students through one of the largest introductory computer science courses at Stanford all online, and will show you how understanding the basics of computer science can be useful in all disciplines, whether you plan to be a developer or you're a social scientist looking for easier ways to manage data. Designed for a lightly technical audience with no previous programming experience.
- UC Berkeley - Computer Science 10 - Professor Dan Garcia - Updated for a new term and a new audience, Dr. Garcia's classic introduction to computer science and computing in our society takes students through topics like algorithms and how businesses around the globe use them to predict almost everything, 3D graphics and video games and how they're developed, social media and communications, social implications of computing, and what the future of computing holds. Designed for lightly-technical audiences.
- Udacity - CS 101: Building a Search Engine - Professor David Evans and Sarah Norell - Designed for audiences with no prior programming experience, this course will walk you through the fundamentals of computer science, how search engines like Google work, how they were developed and built, and finally walk you through the process of building your own search engine, complete with a web crawler and index of highly ranked web pages.
- University of California, Irvine - Computer Science 171: Introduction to Artificial Intelligence - Professor Max Welling - A primer on how artificial intelligences work, and not in the sci-fi sense (although there's more on that later in the class.) You'll study informed and uninformed search, logic, probability, learning, and other programmable characteristics in self-improving systems in this course. Designed for somewhat technical audiences.
- Stanford University - iPad and iPhone App Development (iTunes U) - Professor Paul Hegarty - If you've ever wanted to learn how to build an iOS app, now's your chance. The entire course is a set of free lessons and lectures you can subscribe to in iTunes U, download, and follow at your own pace, complete with exercises and reference materials to help you build your own app from start to finish. You'll need some prior programming experience to make the most of the course though.
Finance and Economics - Extension.org/University of Minnesota - The Road to Financial Security - A web-based, self-taught course from the University of Minnesota that cover critical topics in financial planning for the future, including planning for retirement, adapting your retirement plan to changes at work or unemployment, changing health care needs, and specific financial issues that face parents.
- Utah State University - Family Finance - Professor Alena Johnson - You don't have to have a growing family or children to appreciate the importance of budgeting for your needs, those of your partner, and whatever common expenses you share. This course from Utah State University will help you set and work towards financial goals set by everyone in the household, based on shared values and priorities. Plus, you'll get retirement tips that will help make sure your whole family is happy as you collectively get older.
- Extension.org/Multiple Universities - Preparing Your Finances for Times of Disaster - A collection of articles and self-study one-session web courses that will help you prepare your finances to disasters, including natural disasters, unexpected expenses, and changes in your health or wellness. The course walks you through organizing your legal documents so your family is protected, making sure you have the right insurance to cover natural disasters that may take place in your area, and making sure to budget for emergencies.
- University of California, San Diego - ECON 101: International Trade - Professor James Rauch - Distributed in weekly podcast form, this primer to international trade comes without tests, quizzes, or documentation, but it makes for an amazing listen as you learn about how products move across borders, how governments react to price and currency pressures, and both the political and social implications of multinational companies, their growth, and their expanding reach.
- MIT - Economic History of Financial Crises - Professor Peter Temin - The financial crisis that started in 2008 and 2009 has been a long slog, but looking at it through the eyes of economic history is a great way to make sure similar mistakes don't happen again. This course offers a historical perspective on financial panics through history, including the Great Depression, the Japanese stagnation, the first oil crisis, and of course, the economic downturn of 2008.
Science and Medicine - Tufts University - Physics for Humanists - Professor Gary R. Goldstein - If you've ever wanted to learn more about physics—the science that seeks to understand and explain the very mechanisms behind the universe—but you've been daunted by all of the mathematics required, this course is for you. Physics for humanists will walk you through the history of modern physics, major players in physical science over the past hundred years, what their discoveries mean in a big-picture sense, how far we have to go. The course is designed for people intellectually curious about physics, and covers topics like Heisenberg's Uncertainty Principle, Schrödinger's Cat, General and Special Relativity, and even the interaction between physics and society, like nuclear energy and nuclear weapons.
- Imperial College of London - Physics - A collection of lectures from multiple professors, this series of free courses will walk you through recent discoveries, research, and progress made by physicists around the world. Topics include the search for the Higgs Boson, the now-famous study that posited Neutrinos may be faster than light (later discovered to be mechanical error in the experiment), new testing methods in environmental science, the future of fusion-based nuclear energy, and solar effects on climate.
- HACC, Central Pennsylvania's Community College - Astronomy 103: Introduction to Planetary Astronomy/Astronomy 104: Introduction to Stellar Astronomy - Professor Robert Wagner - These two courses will definitely take up some time, but as someone who has a physics degree and an astronomy degree, I would be doing you a disservice if I didn't offer you both. The Planetary Astronomy course will walk you through the solar system, form the sun all the way out to the Kuiper Belt, current research being done close to home, and the new things we're learning about the planets in our own solar system every day. The Stellar Astronomy course will take you thousands or millions of light years away to learn about some of the mysteries of the universe, like dark matter, black holes, and even tackle Astrobiology and Earth-like planets elsewhere in the cosmos.
- Johns Hopkins University - Principles of Human Nutrition - Professor Benjamin Caballero - Before you sign on with the latest diet craze, take some time to develop an understanding of human nutrition from start to finish. Topics in the course include where to get the essential nutrients for the body to remain healthy, how daily recommended intake levels are calculated, why proper nutrition is so important, and the varying signs of malnutrition, and how diet plays a role in the development of long-term illnesses and other chronic conditions.
- University of California, Irvine - Regulatory Requirements for Pharmaceutical Products - This self-study course walks you through the rigorous requirements by government agencies before a new pharmaceutical product goes from research lab to store shelves or doctor's offices. The course discusses the changing rules over the years, but serves as an exceptional educational tool for those who are either uncertain how rigorous the process is, or are ill-informed as to how the process works, all the way from pre-commercial development through clinical trials, FDA inspections, proper labeling, and acceptable advertising and marketing.
- University of California, San Diego - BIMM 134: The Biology of Cancer - Dr. Jean Wang - Professor Wang walks through the biological underpinnings of cancer, the various types of cancer, the various treatments and wide array of research being done into even the most specific types of cancer, and why cancer is so tough to beat. The course is distributed as a podcast you can subscribe to, and while some prior knowledge of biology will be extremely helpful, you'll be able to pick up a lot without it.
- Johns Hopkins University - Sexual Health, HIV/STI, and Human Rights - Professor Chris Beyrer - Dr. Beyrer's course walks through the delicate intersection between human rights, sexual health, sexually transmitted disease, and how public policy and governments around the world attempt to influence all of those conditions. For example, he discusses how global improvements in human rights at home and abroad can make significant inroads to fighting sexually transmitted infections, and how repressive governments and communities may be doing more harm than good by stigmatizing sexual health, education, and medicine.
Mathematics - The Open University - Math Everywhere - If you're daunted by mathematics, or don't see the value in studying it, this course is for you. You'll learn to see the applications of mathematics all around us, from simple arithmetic and natural law to complicated calculus and advanced statistics that help entire societies make decisions about population growth and where to spend billions of dollars. The course also gets you familiar with your old friend, the graphic calculator—so drag it out of the closet and put some fresh batteries in!
- MIT - Problem Solving Seminar - Professors Hartley Rogers, Kiran Kedlaya, and Richard Stanley - One of the greatest benefits you get from studying mathematics is the ability to look at a problem and come up with a solution. If you find yourself pleasantly challenged by number puzzles and other mathematical problems, or just curious how to bolster your own problem solving and critical thinking skills, this course will help you get reacquainted with them. Students who complete the course can even enter a national mathematics contest to test their skills.
- The Open University - All of the Fun of The Fair - Designed for iOS devices (but not strictly required), this course walks you through an average fair or theme park and helps you understand the underlying mathematics behind four popular carnival rides. This short course details the forces at work so you can begin to see the mathematics under the surface of everyday objects and activities.
Social Sciences, Classics, and Humanities - MIT - Computer Games and Simulations for Investigations and Education - Professor Eric Klopfer - We've discussed how video games can be helpful in the past, but this course takes the topic to a whole new level. You'll learn how we learn from interactive simulations and exercises, how effective those learning methods can be, current research into the issue, and you'll have the opportunity to design your own interactive games, with an emphasis on learning and engagement.
- The Open University - Identity in Question - How is identity formed? What does it mean to be "me?" What influences go into establishing an individual's identity and what they consider to be intrinsic to the "self?" This short course dives into the topic, starting from child-like perceptions of identity, self, and gender, and moving through issues of race, ethnicity, tribe, and how we draw identity from the places that we spend time or grow up in. The course also examines how a person can feel they have multiple identities, often in conflict.
- University of California, Irvine - Anthropology 135A: Religion and Social Order - Dr. Sheila O'Rourke - Religion has played a significant role in social growth, development, conflict, and change since the dawn of civilization. This course walks through the ages, addressing topics of social change, disorder, gender, political and social power, and how all of those elements have changed with the influences of various religions throughout history. The course tackles both classical canon and the theologies of old, and contemporary religions and their applicability to modern conflicts and geopolitical changes.
- MIT - Classics in Western Philosophy - Prof. Rae Langton - Designed for individuals interested in philosophy but without prior training in it, this course looks back to the "founding fathers" of modern philosophy and their work, including Plato, Aristotle, Descartes, Hume, and Kant. Students will tackle the same philosophical questions and challenges they did—the existence of god, where consciousness comes from, what it means to be sentient, and more—and students will use logic and reasoning to come to their own conclusions. The course also examines how the prism of time, society, and external influences change the way we apply that logic.
- University of California, Irvine - Criminology, Law, and Society 219: Hate Crimes - Dr. Valerie Jenness - What exactly is a hate crime, and how is one defined? Depending on who you ask—and their political opinions—you'll get different answers, but there are actually very specific guidelines for what constitutes a hate crime. The course examines those definitions, the social and political contexts in which many hate crimes occur, and the social policies designed to fight bigotry and discrimination in general.
- MIT - How to Stage a Revolution - Professors Jeffrey S. Ravel, Meg Jacobs, Peter C. Perdue, and William Broadhead - Everyone talks about revolution, and how there's desperate need for change in politics and government, including local, regional, national, and global. But how do you go about making that change reality? This course walks through how revolutions across the ages got their start, what caused people to take action, and what took entire nations from talking about change to actually making it happen. Students will study the writings, art, and memoirs of revolutionaries from nations come and gone to understand their motivations, and what made them succeed—or fail.
Law - University of Oxford - Ethics, Law, and Armed Conflict - A series of seminars by various professors and visiting dignitaries, this political science course approaches conflicts in recent history and attempts to answer the question: Was this an ethical conflict? From the international intervention in Libya to the possibility of preventative cyber-warfare, the course asks when a preemptive strike is considered ethical, when an armed conflict can be called a success (if ever), and wrangles with tough topics like whether or not targeted killing and assassinations are ever ethically sound or within the bounds of international law.
- Duke Law School - Theft: A History of Music - Professor Jennifer Jenkins - Dr. Jenkins sees current legal issues around music and technology as not new at all—and neither should you. At the end of this one hour lecture, you'll understand how these problems have persisted for thousands of years. During the renaissance, music publishers were granted monopolies to keep anyone else from printing and distributing music, and even Plato argued once that mixing types of music was disharmonious and should be banned by the state. And yet, even today we struggle with issues of ownership, distribution, and sharing of music. It's a battle that seems to reappear with every new technology and every new generation.
- University of California, Irvine - Immigration Law Symposium - Everyone has an opinion on immigration law, but few actually understand immigration law as it stands. This series of lectures tackles the issue from both sides and features engaging discussions and debates by legal experts with different opinions. The lectures include topics like managing immigration and immigrant populations through criminal law versus outreach, how race and discrimination come into play, our society's institutional values and historical perceptions of immigration, and how immigrants work and find jobs in their host country—whether they're welcome or not.
Cross-Disciplinary Courses and Seminars - Udacity - CS 373: Programming a Robotic Car - Professor Sebastian Thrun and Gundega Dekena - Google's self-driving car is headline fodder for tech blogs around the web, but how exactly does it—and other self-driving systems in development by automakers worldwide—actually work? Dr. Thrun, an AI researcher, will explain how a vehicle can learn and adapt to its surroundings, and how designers and developers integrate tracking and control systems, localization utilities, and other robotic systems into the vehicle. You'll need programming knowledge to make the most of this course, but you can still watch and be fascinated without it.
- MIT - Inventions and Patents - Dr. Robert Rines - This course will walk you through the history of public and private rights when it comes to engineering, inventions, gadgets, solutions, and even software. The focus is on patent law in the United States, and how individuals can apply for patents for their inventions, how patents are handled in a legal context, and more. Technology isn't the only application either—the course discusses the role of discovery and patenting in a medical and pharmaceutical context, and even in terms of genetic engineering and whether a company or person can "own" a gene sequence or modification technique.
- Carnegie Mellon University - Logic and Proofs - This self-guided course will teach you the basics of using symbolic logic to develop and support arguments and positions. The course's focus is on strategic argumentation, and while you can't be there in person to demonstrate, you can still practice your deductive skills and how to present arguments at home.
- Emory University - Emory Looks at Mad Men - Emory professors discuss the racial, social, and historical aspects of the popular television show. How accurate is the historical portrayal of advertising, or of society? The course is currently on-going, and available to subscribe to via iTunes U.
- University of South Florida - Social Media - Most of us use social media to tell our friends what we're up to and stay close to people who are far away from us, but businesses are using it to make big bucks. What is social media exactly, how do people gauge trends in social media, and what role does social media play in politics, government, and even political rebellion? This course tackles all of those topics, as well as how you can use social media for your personal and professional life.
