When an experiment can't be repeated with the same conditions there's only a few explanations;
a) there's something you aren't accounting for so it isn't the "same"
b) you are the variable
c) you are switching universes in between experiments
d) there are science goblins messing with your mind
All of these options reminded me of this song
The chorus is
"There are monsters here
And as you scream it makes no sense
It makes no sense
It makes no sense at all "
That pretty much sums up the last 2 weeks of work for me.
