GILBERT STRANG: Hi, I'm Gilbert Strang, and professor of mathematics at MIT. And I get a chance to say a few words about 18.06, Linear Algebra. It's one of the basic math courses. Can I say a little about linear algebra itself? Classes in linear algebra earlier years tended to be pretty much for pure math majors, and a lot of proofs, and usefulness... Read More
