I’m working on a presentation around the number “50”. I’m not a strong math guy, but I use mathematic principals and effects with numbers often . Wondering if anyone knows anything that might be unique or interesting about this number (even a number close to it). I don’t know what I don’t know, but you might. Could be a force, a trick or just a unique quality of the number. Thanks for helping me crowd source possibilities, I do appreciate it!
