Question: What is your favourite thing to fix?

My calculations when I eventually screw something up! I was once playing around with a set of equations which described how the universe was expanding (Called the Friedmann equations if you’re interested…). I accidentally managed to prove that the universe didn’t exist… I spotted this because I was trying to take the square root of a negative number (which you can’t do!). I found it quite fun going through my workings and trying to “fix” my mistake =).
