- Purpose of use
- Had a silly little idea I rattling around in my head for years. Thought I could prove it wrong and put it to bed. Turns out it''s valid to more than 16 decimal points. Now I have to kind a competent physicist and ask him how WTF??? Thanks so much, if I had found this site earlier I would be finished now. ;-)

- Purpose of use
- Super useful for determining the power of a 2 cm diameter tungsten ball used in a Relative Kinetic Kill Vehicle.

- Purpose of use
- Research into the destructive potential/ Hard Science fiction

- Purpose of use
- Generator
[7] 2017/07/25 10:18 Male / 60 years old level or over / Self-employed people / Very /
- Purpose of use
- To determine what fraction of a mass would be needed to accelerate a mass to relativistic speeds. To accelerate to 0.2c about 2% of a mass would need to be converted to energy. I've been thinking about the Fermi Paradox and this was good information.

- Purpose of use
- Fact checking
[9] 2014/03/31 00:15 Male / 40 years old level / Others / Very /
- Purpose of use
- Double checking math, personal interest, non-school related.
