Sigma September.
Tuesday, September 1st, 2020
We started this year visiting Seattle’s Living Computers Museum. It subsequently closed during the pandemic lockdown and remains “closed for now,” an apparent victim of the economics of pandemics.
The letter Σ (sigma), can be, in mathematics, a symbol for summation.
Σ[1,2,3,4,5,6] = 21.
Wikipedia of course has all kinds of arcane uses for sigma.
Σ is the capitalized Greek letter, by the way. The lowercase one is apparently σ but ς in the final position of a word. I really never want to learn Greek.
9, of course, can refer to the ninth month of the year. We’re starting it now! Last chunk of 2020! We can do this!
This particular computer ran for years handling medical billing, well into the era of the personal (desktop) computer. It’s very very large and very very heavy and who knows where it will end up now.
