# Comments for A Simple Time Machine

Sir,

I constructed your time machine as instructed, but was disappointed to find that it does not work as described. I too planned to travel only a short distance in my initial test, but found the distance traveled was shorter than calculated by your formula. I believe this is due to the omission of a factor of exp(exp(-i*pi)) in your time-difference-equation.

See you in the future....Sir,

My time travel experiment was likewise unsuccessful, but so was my attempt to fix the problem by reinserting the constant discussed by Terry above (which, being entirely new, I propose to name "Terry's constant"). I believe this is due to an excess of exp(), or expcess, if you will.

After an exhaustive study in which I tested all functions in alphabetical order, I have found the correct adjustment to make. The numerator in your infinite summation should not be 1 at all, but (ln T)^k, where T is Terry's constant. This will cause the sum to stop increasing without limit, and instead somehow "zoom in" on a particular value -- a bizarre phenomenon that requires further study.

Regards,

your future self

*Unknown [DwE4KFYW2]*:Wuffle2013-10-30 08:06:02.000ZThis is amazing, and a bit crazy, but true. I just time travelled WITHOUT building the machine! I began reading these instructions on building the machine, and lost a full 10 minutes. I'm convinced I only took 3 minutes to read it. Well, you do the math. (ok, I'll do it; endTime - startTime = totalTime; 9:45 - 9:58 = -13 minutes; totalTimeLost - actualTimeToRead; -13 - (-3) = 10 minutes unaccounted for)...

WHOOoooa! I just noticed I did it again. And it's around 10 minutes again. Could this be a new constant? At this rate I'll either be at the end of my life in no time or live for a very long time; it's relative, I think.
