Truth or Utility

What does science know about reality? Since science works from particulars, how can it claim to give universal truths? I think of science as a collection of ideas, organizing empirical facts. That is, scientific laws are contingent on what facts we have. They are to be measured, in my opinion, not by their truth, but…

So 85+% of energy is already…

Black Hole Derivation

I was fiddling around with a particle accelerating to the speed of light in a gravitational field and arrived at the Schwarzchild radius. A nice surprise 24 years ago.


A sphere has 14% of its volume in its crust. A hypersphere of dim 19, has 62% of its volume in its crust.
