68 utterly useful free online courses by harvard, mit, & more

Whether you are ten or seventy, there are still tons of things to learn. When the topic is education, the internet is like an ocean, and the resources on the internet are endless. And we are

so lucky because many Ivy League colleges offer tons of completely free courses. I have made a list of the best free online courses from the top eight universities globally so that you can

learn from home. HERE ARE 68 AMAZING FREE COURSES FROM HISTORY TO CODING. STANFORD UNIVERSITY MACHINE LEARNING — 11 WEEKS Machine learning involves getting computers to act without being

explicitly programmed. In the past decade, machine learning has given us self-driving cars, practical speech recognition, effective web search, and a vastly improved understanding of the

human genome. Machine learning is so pervasive today that you use it dozens of times a day without knowing it, and many researchers also think it is the best way to progress toward

human-level AI. In this class, you will learn about the most effective machine-learning techniques and practice implementing them and getting them to work for you. More importantly, you will

learn not only about the theoretical underpinnings of learning but also gain the practical know-how needed to quickly and powerfully apply these techniques to new problems. Finally, you

will learn about some of Silicon Valley’s best practices in innovation regarding machine learning and AI. INTRODUCTION TO MATHEMATICAL THINKING — 9 WEEKS Learn how to think the way

mathematicians do — a powerful cognitive process developed over thousands of years. Mathematical thinking is not the same as doing mathematics — at least not as mathematics is typically

presented in our school system. School math typically focuses on learning procedures to solve highly stereotyped problems. Professional mathematicians think a certain way to solve real

problems, problems arising from the everyday world, science, or mathematics itself. The key to success in school math is to learn to think inside the box. In contrast, a key feature of

mathematical thinking is thinking outside the box — a valuable ability in today’s world, and this course helps to develop that crucial way of thinking. CRYPTOGRAPHY I — 7 WEEKS Cryptography

is an indispensable tool for protecting information in computer systems. This course will teach the inner workings of cryptographic systems and correctly use them in real-world applications.

The period begins with a detailed discussion of how two parties with a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. You will

examine many deployed protocols and analyze mistakes in existing systems. The second half of the course discusses public-key techniques that let two parties generate a shared secret key.

Participants will be exposed to many exciting open problems throughout the course and will work on fun (optional) programming projects. GAME THEORY — 13 WEEKS Popularized by movies such as

“A Beautiful Mind,” game theory is the mathematical modeling of strategic interaction among rational (and irrational) agents. Beyond what we call `games’ in everyday language, such as chess,

poker, soccer, etc., it includes modeling conflict among nations, political campaigns, competition among firms, and trading behavior in markets such as the NYSE. How could you begin to

model keyword auctions and peer-to-peer file-sharing networks without accounting for the incentives of the people using them? The course will provide the basics: representing games and

strategies, the extensive form (which computer scientists call game trees), Bayesian games (modeling things like auctions), repeated and stochastic games, and more. You will include a

variety of examples, including classic games and a few applications. INTRODUCTION TO FOOD AND HEALTH — 5 WEEKS In this course, learners will be given the information and practical skills

needed to optimize their eating. This course will shift the focus away from reductionist discussions about nutrients and toward practical discussions about real food and the environment in

which we consume it. By the end of this course, learners should have the tools to distinguish between foods that will support their health and threaten it. In addition, you will present a

compelling rationale for a return to simple home cooking, an integral part of our efforts to live longer, healthier lives. CHILD NUTRITION AND COOKING — 5 WEEKS Eating patterns that begin in

childhood affect health and well-being across the lifespan. The eating culture has changed significantly in recent decades, especially in parts of the world where processed foods dominate

our dietary intake. This course examines contemporary child nutrition and the impact of the individual decisions made by each family. INTRODUCTION TO STATISTICS — 8 WEEKS Statistics is about

extracting meaning from data. In this class, you will be introduced to visualizing relationships in data and systematic methods to understand relationships using mathematics. STATISTICAL

without heavy reliance on formulas and complex mathematics. You focus on what we consider essential elements of modern data analysis. Computing is done in R. There are lectures devoted to R,

giving tutorials from the ground up and progressing with more detailed sessions that implement the techniques in each chapter. MINING MASSIVE DATA SETS — 7 WEEKS The course will discuss

data mining and machine learning algorithms for analyzing vast amounts of data. The emphasis will be on MapReduce and Spark as tools for creating parallel algorithms to process huge amounts

of data. INTRO TO ARTIFICIAL INTELLIGENCE — 16 WEEKS Artificial Intelligence (AI) has a long history but is constantly growing and changing. In this course, you will learn the basics of

modern AI as well as some of the representative applications of AI. Along the way, I hope to excite you about AI’s numerous applications and possibilities, which continue to expand human

capability beyond our imagination. UNDERSTANDING EINSTEIN: THE SPECIAL THEORY OF RELATIVITY — 8 WEEKS In this course, you will seek to “understand Einstein,” mainly focusing on the

particular theory of relativity that Albert Einstein introduced as a twenty-six-year-old patent clerk in his “miracle year” of 1905. Your goal will be to go behind the myth-making and beyond

the popularized presentations of relativity to gain a deeper understanding of Einstein, the person, and his theory’s concepts, predictions, and strange paradoxes. PROGRAMMING MAX:

STRUCTURING INTERACTIVE SOFTWARE FOR DIGITAL ARTS — 13 WEEKS Max is a powerful platform that accommodates and connects various sound, graphics, music, and interactivity tools using a

flexible patching and programming environment. Max allows most computer users to write a simple, meaningful program within a few minutes, even with limited programming knowledge. However, to

entering the industry at a higher level, with considerably greater perks and privileges. HUMAN RESOURCES — 20 HOURS One of the few things every business and organization has in common is its

reliance on human resources. Exactly how well or otherwise a business performs will always be determined by the human resources that make up the workforce. Human resource managers oversee

the workforce’s creation, development, advancement, and general management. From initial hiring to ongoing training and disciplinary proceedings, the HR manager is the linchpin that holds

the team together. INTERNET MARKETING — 20 HOURS Internet marketing is quickly replacing traditional marketing as the primary go-to for a new generation of businesses worldwide. The power of

digital marketing has already vastly outshined that of conventional marketing strategies — a trend that is only set to continue indefinitely. As the world becomes increasingly digitized,

the influence of traditional marketing platforms like television, print, and radio is diminishing rapidly. At the same time, those with advanced digital marketing skills are becoming an

increasingly priceless asset in the eyes of business leaders and recruiters, spanning the vast majority of contemporary sectors. If you like the idea of building a career in internet

manager. If you are interested in climbing the career ladder as quickly and efficiently as possible, you need to see yourself as both. While management is generally associated with control,

processes, operational standards, and leadership, leadership is more about inspiration and vision. Combine the two, and the result is a professional of outstanding caliber with the potential

to succeed in almost any modern industry. PUBLIC RELATIONS — 20 HOURS Public opinion is the most powerful and influential factor in determining whether any business or organization will

succeed. The same is true across private and public sectors — public opinion has the power to make or break a brand in record time. Just as strong public opinion can propel a business to

succeed instantly, a poor reputation can have the opposite effect. The internet has made constant and aggressive reputation management more important than ever — a process orchestrated and

managed by PR professionals. If PR is the career you can see yourself succeeding in, this exclusive free course from Oxford Home Study College could represent the perfect starting point!

PROJECT MANAGEMENT — 20 HOURS All over the world, businesses and organizations in every capacity are fundamentally reliant on projects to grow, evolve and succeed. Absolutely any

limited-time activity that is undertaken with a specific goal in mind represents a project. Projects vary from new product introductions to service alterations to expanding into new

territories. Projects can be relatively simple or spectacularly complicated, though in all instances are planned, implemented, managed, and optimized by professional project managers. If a

career in management with no limitations appeals to you, this 100% FREE PROJECT MANAGEMENT COURSE could be right up your street. RISK MANAGEMENT — 20 HOURS The divide between risk and

opportunity is so fine that they are often seen as the same. Every opportunity that comes along must be considered by its risks; just as much is taken to make the most of any opportunity. It

is, therefore, how risks are approached and controlled that will often determine whether or not it is a risk worth taking. Risk managers play a critically important role in almost every

business environment, tasked with minimizing threats and maximizing opportunities. Risk managers take control wherever risk exists, from business expansion efforts to new products to

employee health and safety. STARTING ONLINE BUSINESS — 20 HOURS One of the biggest privileges the internet has brought to the modern world is establishing and managing your own business with

nothing more than a computer. Setting up a business from scratch these days is a process that can be completed in minutes — much of the process has been simplified or even automated by

intelligent software. All you need is a vision, a workable idea, relentless commitment, and the business/technical skills required to get things off the ground. If the idea of becoming your

boss appeals to you, this exclusive free Starting an Online Business Course could be just the thing to steer you in the right direction. SUPPLY CHAIN COURSE — 20 HOURS In almost every

business setting, there will be some supply chain that facilitates everyday operations. From initial manufacturers to delivery services to storage facilities to High Street stores, the

supply chain represents the combination of links/contributors that result in customers being provided with products or services. Just like a chain, absolutely every link is reliant on every

other — if a single linking the chain fails, the chain as a whole cannot function. Building, maintaining, and optimizing supply chains can be challenging and complicated, which is precisely

why businesses hire elite supply chain managers to oversee the process. DEEP LEARNING FOR NATURAL LANGUAGE PROCESSING This is an advanced course on natural language processing. Automatically

processing natural language inputs and producing language outputs is a crucial component of Artificial General Intelligence. The ambiguities and noise inherent in human communication render
