If you're doing complicated math or physics, the last thing you want is to be off by a multiple of 2 when you're done. It's happened to me enough times, I almost wish I were still doing physics so I could use tau instead of pi.
For electron charge, I have, at times for intermediate calculations, used 'e' in place of the negative sign from electrons, and then substituted -1 at the end. Being off by a multiple of -1 is just as annoying as a multiple of 2.
- billswift 16y agoEven more annoying since it is even easier. Losing a negative sign is the most common mistake I make working through a complicated problem. Your idea of using something less likely to be overlooked when transcribing intermediate steps in solving a problem strikes me as a really good idea. Thanks.
