The "I don't want to talk about AI" thread, and the new topic is: the Big 0

Marcus du Sautoy is a researcher who specializes in the history of 0. He had identified a Hindi temple as the first usage of 0, in the 600's, I believe. About two years ago, he identified a much earlier usage in a hindi manuscript. The western usage of 0 (and our digits) almost certainly came from India, through the Islamic middle east, then Fibonacci brought it into Europe.

If you want a simplification of this history, he made a BBC/PBS film (about 55 minutes long) detailing this. It's called The Story of 1 and is on YouTube.

But other cultures did understand zero and could express it. Quipas (many varant spellings from different transliterations) are pre Colombian new world knot systems that describe sequences of numbers, including zero.
Makes sense.
 
I read that as big O, which has a very specific meaning to computer scientists. And someone called college professors stuffy in another thread.

Well, akshually, it's the Greek letter omicron, and besides, y'all should be using the big theta instead, like Cormen et. al. intended!
 
I do realize that -- my dissertation was mostly theory -- but saying I did my doctoral research on the big O is so much more fun then trying to explain isomorphism groups..
 
My cat Dot was sitting on my lap last night, enjoying some skritches when the dog barked six feet away. Peroxide was involved.
I still have a visible scar on my thigh from where my cat was sleeping in my lap two months ago and thought something was coming. I think she dreamed it. She apparently needed to be 6 feet past me in that instant.
