I often talk about the coldest day in history, July 21, 1983, because it is the day I was born.

One thing I overlooked all this time is how the Mercury hit its lowest point, and the temperature was approximately -129° F. Of course, 129 is 201 in base 8 counting, and Mercury’s Atomic Weight is approximately 201. Keep in mind this record stat came one day after the 201st day of ’83.
