<blockquote> | |||
0.5 ...when I have to describe what General Relativity is, and I don't wish to lie the way everyone else lies (if I'm going lie I'm going to do it differently) I say that: | |||
1. You have to begin with 4 degrees of freedom | |||
2. And then you have to put rulers and protractors into that system so that you can measure length and angle. | |||
3. That gives rise miraculously to a derivative operator that measures rise over run | |||
4. That rise is measured from a reference level | |||
5. Those reference levels don't knit together | |||
6. And they form Penrose stairs | |||
7. And the degree of Escherness, or Penroseness, is what is measured by the curvature tensor | |||
8. which breaks into three pieces | |||
9. you throw one of them away, called the Weyl curvature | |||
10. you readjust the proportions of the other two | |||
11. and you set that equal to the amount of stuff. | |||
12. It is linguistically an accurate description of what General Relativity actually is. | |||
13. It also illustrates cohomology | |||
