@@CHAP@@ Chapter I Can You Get an MIT Education Without Going to MIT?
Only a few hours left. I caught myself glancing out the window as the early-morning light glittered off the buildings in front of me. It was a crisp fall day, surprisingly sunny for a famously rainy city. Well-dressed men carried briefcases and fashionable women pulled miniature dogs beneath my eleventh-story vantage point. Buses dragged reluctant commuters into town one last time before the weekend. The city might have been rousing from its slumber, but I had been awake since before dawn.
Now is not the time for daydreaming, I reminded myself and shifted my attention back to the half-finished math problems scribbled on the notebook in front of me. “Show that for any finite part of the unit sphere . . .” the problem began. The class was Multivariate Calculus for the Massachusetts Institute of Technology. The final exam would start soon, and I had little time left to prepare. What was curl, again . . . ? I closed my eyes and tried to form a picture of the problem in my head. There’s a sphere. I know that. I conjured a bright red ball in my mind’s eye, floating in empty space. Now what was n̂? The n̂ stands for normal, I reminded myself, meaning an arrow that points straight up from the surface. My red ball became furry, with hairlike vectors standing straight at all ends. But what about curl? My imagination turned to waves of tiny arrows pulsating in a vast sea. Curl marked the eddies, swirling around in little loops. I thought again to my furry, red ball with the static-charged hairdo. My fuzzy sphere had no whorls, so there must not be any curl, I reasoned. But how do I prove it? I scratched down some equations. Better double-check it. My mental pictures were clear, but my symbol manipulation was a lot sloppier. There wasn’t much time left, and every second of preparation counted. I needed to grind through as many problems as possible before time ran out.
That was nothing unusual for an MIT student. Tricky equations, abstract concepts, and difficult proofs are all a normal part of one of the most prestigious educations in math and science in the world. Except that I was not an MIT student. In fact, I had never even been to Massachusetts. All of this was taking place in my bedroom, twenty-five hundred miles away in Vancouver, Canada. And although an MIT student typically covers the entirety of multivariate calculus over a semester, I had started only five days before.
@@CHAP@@ The MIT Challenge
I have never attended MIT. Instead, my college days were spent studying business at the University of Manitoba, a middle-ranked Canadian school I could actually afford. After graduating with a bachelor of commerce, I felt as though I had picked the wrong major. I wanted to be an entrepreneur and so had studied business, thinking that would be the best route to becoming my own boss. Four years later, I discovered that a business major was largely a finishing school for entrants into the world of big corporations, gray suits, and standard operating procedures. Computer science, in contrast, was a major where you actually learned to make things. Programs, websites, algorithms, and artificial intelligence were what had interested me in entrepreneurship in the first place, and I was struggling to decide what to do about it.
I could go back to school, I thought. Enroll again. Spend another four years working toward a second degree. But taking out student loans and giving up a half decade of my life to repeat the bureaucracy and rules of college didn’t seem very appealing. There had to be a better way to learn what I wanted.
Around that time, I stumbled across a class taught at MIT and posted online. It had fully recorded lectures, assignments, and quizzes; even the actual exams used in the real class with the solution keys were provided. I decided to try taking the class. To my surprise, I found that the class was much better than most of the classes I had paid thousands of dollars to attend in university. The lectures were polished, the professor was engaging, and the material was fascinating. Digging further, I could see that this wasn’t the only class MIT offered for free. MIT had uploaded the materials from hundreds of different classes. I wondered if this could be the solution to my problem. If anyone could learn the content of an MIT class for free, would it be possible to learn the content of an entire degree?
