Weekly Physics: Ballistic Motion
This gives us that the y component of the velocity (which is zero) equals the y component ... times the inverse sine of the distance between Bob and Tom times 9.8 m/s^2 divided the square of the initial velocity. ( theta = .5 * sin-1( d * 9.8 / V0^2 ...
Dirty Rotten Infinite Sets and the Foundations of Math
Today we’ve got a bit of a treat. I’ve been holding off on this for a while, because I wanted to do it justice. This isn’t the typical wankish crackpottery, but rather a deep and interesting bit of crackpottery. A reader sent me a link to a website ...

In short, Ron Paul is a simpleminded fool on 90% (at least) of the issues, domestic and foreign. There have been no good consequences or byproducts of his candidacy, he has worsened the already abysmal US political discourse, he has not forced any ...
The needle in the haystack
Writing for the Hoover Institution, Russell painted a picture of sclerotic and constipated process: The Central Intelligence Agency is the “first among equals” in the intelligence community and deserves particularly close independent scrutiny.
Angle of Radiation - What is it?
The angle of radiation = sin-1 (0.25/h) where h = the antenna height above ground in wavelengths. (The sin-1 is inverse sine but I couldn't get it to ... is not nearly as critical as with a vertical. Thanks for the post. For a while I used a low hanging ...
