Science and math issues that draw my interest and effort.

Soft Sciences, Hard Sciences

Russia and Oil Prices

In the Twilight Zone episode (1960), ‘The Hitchhiker’ a sign shows gas at 32.9 cents/gal. Now it’s about 10 times higher. What’s that inflation rate?

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