I understand this is all some rhetorical device, but basically all of the facts he quotes about the domains I know are wrong.
- dragontamer 12y agoIndeed. NIST was right down the road from my university, and we were constantly reminded that "universal constants" are really just statistically measured values. There was nothing quite "Here's the value of gravity for today:" set to 15 digits, officially from NIST. Remember people, Gravity is a measured value, a _statistic_. The modern transistor in electronic circuits are also measured values. Depending on the fabrication process and other junk, every transistor on a CPU is in fact different. A huge amount of work goes towards making every transistor on a CPU work similarly to each other (as well as statistics to measure the variance). A world without statistics is a world without modern silicon computers. And I bet you that Vacuum Tubes were similarly measured and specified thanks to statistics.
