Space Calc

Welcome!

Want your story / game / RPG / thought-experiment to be scientifically accurate, but don't want to be constantly looking up poorly explained formulae while banging your head against a calculator?

I've got you covered. This site contains handy JavaScript tools for simulating, calculating, and deriving in your favorite space/sci-fi context. Many calculators also come with detailed explanations, derivations, or equations—but the calculator is always there first, in case you just don't care and only want the numbers.
