only works in 2D.
in 3D, prob. of ‘drunken walk’ approaches zed.

“two of the objects might orbit each other closely while the third is flung into a wide orbit”
I got flung once as described here. ...out of a mosh pit.
The third object generally lands on it’s ass and slides a short distance before it’s friends hand it it’s drink and tells it to get back in the pit which the third object is more than happy to oblige.
Here, hold my beer.

At this point they seem satisfied with probability rather than certainty. Seems inadequate, still.

Calculus is the mathematics of approximations. At some point the approximations are ‘close enough’.................

Euler?
Lagrange?
The Hillary Klintoon walk?
As a retired physicist, sure glad I retired in 1985...

That’s why designers, engineers and architects put tolerances on drawings/models.

I just came upon a drawing of Newton with the following verbiage overlaid:
“Think you’re bored? Sir Isaac Newton invented calculus during the plague. Do you have any idea of how bored you must be to invent calculus?”
Wish I had seen this years ago when I was teaching some grad math. ‘Twould have added some humor to “Calculus on Manifolds”.

My very first computer program was for a school assignment to encode numerical solutions the restricted three-body problem. Earth, Moon and spaceship, for example. You can get a good handle on that.
As for this project, I’m not sure that assigning probabilities to different outcomes is the same as “cracking” the problem. As usual, the headline writer promises much more than the researchers do themselves.
To: Waverunner
“That’s why designers, engineers and architects put tolerances on drawings/models.”
Those are manufacturing tolerances.
There are no tolerances in the above, only probabilities of a given outcome.

..."initial conditions" — that is, whatever speed and position they were in previously. Heisenberg says that is impossible to know................

(The above is not a statement of fact. It is either opinion, or satire. Or both.)
To: Red Badger
"[The three-body problem] depends very, very sensitively on initial conditions, so essentially it means that the outcome is basically random,"... Translated: We cannot characterize the intial conditions properly, so we cannot solve the problem.

Differential Calculus is the mathematics of approximations.

Heisenberg didn’t know if his cat was alive or dead... LOL
