Open course ware

STEVE LERMAN: Welcome. I know there'll be a few additional people. And if people could slide over, that'd be great, as new people arrive. It's my pleasure to welcome all of you here today. My name's Steve Lerman. And I've been at MIT a long time, but I certainly, for this occasion, my singular honor has been to be associated with OpenCourseWare since its inception. I served as chair of the Interim Management Board and am now chair of the Faculty Advisory Board. It's my privilege to be your emcee today. But in fact, while this event is meant to honor the achievements of OpenCourseWare, I sort of like to emphasize my own view that the best is still yet to come. In 2001, MIT made an extraordinary commitment to publish in electronic form the teaching materials we use in virtually all our courses, the entire undergraduate and graduate curriculum of this institution. And we committed to make those materials freely and openly available for any non-commerc...

PROFESSOR: All right, welcome. We have some fun origami topics today, mostly related to a topic called pleat folding. General idea of pleat folding is to fold alternating mountains and valleys back and forth. And you can do a lot of cool things with pleat folding, and that's what I want to talk about today. In particular, this model is usually called the hyperbolic paraboloid. It's pretty simple. You start with a square paper. You fold this crease pattern, which is concentric squares alternating mountain and valley, and you fold the diagonals, alternating mountain and valley. You crush it all together, you'll get this sort of x-shape. And you sort of let go, give it a twist, and it pops into this saddle form, which looks a lot like a hyperbolic paraboloid, which is one of the standard saddle surfaces. It's approximating a hyperbolic paraboloid, we think, or we thought, and that's why it's called that. So you should all try this at home. It's a ...

Hello, everyone. Welcome. I'm Krishna Rajagopal, MIT's Dean for Digital Learning. And I'm here to welcome everyone to this joyous occasion as OpenCourseWare turns 20. Today, we celebrate OCW's first 20 years, and look ahead to the potential and the plans for OCW, and the entire ecosystem of open educational resources that OCW sits within, in its next 20. The mission of OCW since its founding was to unlock knowledge and empower minds by publishing materials from virtually all MIT courses, and extend the reach of those materials via the OER movement which OCW played a key role in seeding. Charles Vest, who is the president of MIT who launched OCW 20 years ago, spoke at that time about how surprising and audacious the vision of OCW that came to him from a founding group of MIT faculty members was. Put all of our materials on the internet, openly? This came as a big surprise to President Vest 20 years ago. One way to see how right the faculty were back then, t...
