WOW! I’m impressed, I guess ... what the heck are they talking about?

When two objects are orbiting one another under the influence of gravity, how will they move around one another? For any time in the future can you predict where they'll be with respect to one another, how fast they'll be moving, and in which direction. Newton solved that problem 300 years ago.

Can you do the same for three bodies? Mathematically, it's a much more difficult problem, which is surprising. As the article says, Euler made some progress. Personally, I was unaware that any further advancements had been made. I just figured it was one of those intractable things and that was that.

And four bodies, five bodies, etc.? Fuggedaboudit.

Check out the wiki article.

Pretty exciting.

” - - - what the heck are they talking about? - - - “

1.) The essence of a great manager: Ability to keep many balls in the air.

2.) Juggling 3 objects in space.

3.) Opposites attract, but three is a crowd.

4.) One if by Land, Two if by Sea, and Three is one of those damn Obamadrones!

Thank you for clearing that up somewhat. I will research now that my curiosity has been peeked.

French scientists discovered it first, called it a Menage a` Trois

Very cool. Can’t wait for someone to code up a simulator for it that I can run on my desktop.

Doesn't that involve 3 competing French socialist "brigades" attempting to not engage each other, while gloriously looking for a fight?

Ok, who is up for solving the problem for four bodies?

“Enquiring minds want to know.....”

We are just dying to know!

Newton solved that problem 300 years ago.

It might be more accurate to say that Newton placed a theoretical foundation under Kepler's solution. (Though Kepler thought planets orbited the sun, not the center of mass of the sun-planet system. Thanks for clearing that up, Isaac.)

It is also inaccurate to say that Newton did not solve the three (or many body) problem. The answer today is the same as it was in Newton's day, as my Gujarati Calculus professor would say, "Integrate, only." It's like Woody said about Buzz Lightyear, "That's not flying, that's falling with style." Same thing, these are not closed from solutions, they're integrating with style.

This is a classic Mafia math problem. Youse got three bodies, a large garbage bag and enough space for one and a half bodies in the trunk of youse car. The bodies is in a public spot where dey might be discovered at any moment. How do youse get rid of da bodies? (Use a no. two axe. Show all work.)

I would like to see all of the orbit animations in real space.

Me, too! Must take a long time for them to trace out those intricate butterfly patterns? They should just speed it up a thousand fold if necessary and let us see it!
