<div style="color:#00000a;">[01:12:33] is going to be the vertical tangent space of 10 dimensions to U direct sum, the four dimensional cotangent space which we're going to call horizontal to U. And the great thing about the chimeric bundle is, is that it has an a priori metric. It's got a metric on the four a metric on the 10 and we can always decide that the two of them are naturally perpendicular to each other.</div> | <div style="color:#00000a;">[01:12:33] is going to be the vertical tangent space of 10 dimensions to U direct sum, the four dimensional cotangent space which we're going to call horizontal to U.
