...frustrated by all the things that had to be done to make another run after fixing an error, she devised a way to bypass the computer’s clunky debugging process. To Lorenz’s delight, Hamilton would take the paper tape that fed the machine, roll it out the length of the hallway, and edit the binary code with a sharp pencil. “I’d poke holes for ones, and I’d cover up with Scotch tape the others,” she said. “He just got a kick out of it.”
Many accounts, including the one in Gleick’s book, date the discovery of this butterfly effect to 1961, with the paper following in 1963. But in November 1960, Lorenz described it during the Q&A session following a talk he gave at a conference on numerical weather prediction in Tokyo. After his talk, a question came from a member of the audience: “Did you change the initial condition just slightly and see how much different results were?” “As a matter of fact, we tried out that once with the same equation to see what could happen,” Lorenz said. He then started to explain the unexpected result, which he wouldn’t publish for three more years. “He just gives it all away,” Rothman said now. But no one at the time registered it enough to scoop him.

Long ago everyone I knew did fractals.
Pecking in a few lines from MICRO CORNUCOPIA, let the Z80 grind away all night… look almost a quarter of the screen... Now I need to find my old copy of Fractint… and maybe update it…
A long read about some esoteric but of history, with a PC bias.
If you were ever taken by a strange attractor, you may enjoy this article.
Yes, everyone knows that Einstein's first wife did all the heavy lifting and he took all the credit...
I have to go to work in an hour but when I have a few hours to look up all the words I dont understand in YOUR POST ALONE :), I’ll get to it!
You sound like a smart fella.
The first half of your screen name suddenly doesn’t feel fitting anymore :)
You sound like a smart fella.
Or maybe not.
Rest assured, two minutes or less speaking with my wife.
You will know the facts.
Now it’s a challenge that I have bookmarked to read tonight. :)
I’m halfway smart :)
But never liked reading books, whether they be fiction or factual..history...current events...science.
As a result I find myself looking up words in posts rather regularly.
I’m good with that.
Learning new things is good for the brain as one gets older, so they say :)
Yet leftards think that they are able to predict the weather 100 years from now.
I did my PhD work in nonlinear dynamics - Chaos Theory/Fractals. Looked at it with a Information Theory twist. Biological world is full of fractal relationships.
The funny thing is, astrophysicists found this out a long time ago trying to model systems that are a lot less complex than weather systems. Just trying to model the movement of bodies in the solar system, they discovered that it was impossible to accurately predict the movements of a dynamic system to a great degree of accuracy once you got beyond just a couple of moving parts.
The French mathematician/physicist Poincare (April 1854 – 17 July 1912) did work in that arena - “the 3 body problem”.

Similar to the famous constipated mathematician?
Yes, he worked it out with a pencil!!!!
that’s an oldie. and please
excuse the lack of capitals.

A nice old Pickett dual base?
Nice!
I’d steal that line if only, I can remember it!!!
