He grabbed the wrong part

I had the butterfly effect wrong
for twenty years.

You know the butterfly effect. A butterfly flaps its wings in Brazil, and a few weeks later there is a tornado in Texas. Everything you do matters, that sort of thing.

I have said that line for years. The man who came up with it never said it.

He turned up to a talk in 1972 with no title for it, so somebody else wrote one for him. Before that he had been using a seagull. And in the same talk he said the flap could just as easily stop a tornado. A butterfly moves so little air that the push turns into heat and is gone.

What he did find is better. In 1961 he typed a number into his weather computer and got it slightly wrong. 0.506 instead of 0.506127. He went for a coffee. When he came back the computer had made two months of weather that looked nothing like the first go.

Peoria, 1943. This one finished penicillin.

So a butterfly cannot do it. But small things change big things all the time. When they do, people write reports about it. A rocket blows up and by law you go and find the smallest thing that started it.

We read those reports. Ten of them.

The thing at the top is a resistor. In 1956 a man reached into a box and picked up the wrong one. What he built by accident was the first pacemaker. It is in millions of chests now.

I make one of these most weeks. The bigger builds live in the Hidden Tab, a few dollars a month.

And if you have not played Long Story Short, today's sentence is a good one.

Know one I missed? Hit reply and I will put it on the page.
