@cinebox people often wonder why it takes so much fuel to put a tiny rocher into space. but to carry rocher into space you need fuel, and to carry that fuel into space to burn it later, you need even more fuel. the solution to this conundrum was first described by russian scientist Konstantin Tsiolkovsky, and is therefore known as the Tsiolkovsky rocher equation

@daniel_bohrer @cinebox @amiserabilist ‘rocher’? You mean ‘rocket’?
