Watching 3 body problem and remembering a nitpick I have with it (spoilers for the VR game plot) (hexbear.net)

So the computer based solution proposed by Newton and Turing is rejected because the system is chaotic, meaning a general solution will always diverge from reality.

What I don't get is: this should still be good enough Run your solution every month or so, with updated measurements, and you'll have an ongoing "forecast" of conditions.

I'm referencing weather because that's we do. A weather forecast is a prediction of a chaotic system, but of one which changes every day or so. Prediction difficulty is dependent on local conditions and weather type, but we can still make predictions.

A gravitational system of 4 mutually interacting bodies is muuuuuch simpler than weather, and could be predicted far enough in advance to let a civilization adapt and persist!

The Netflix series have altered a lot of the book’s plot.

You remembered correctly about the books, the Trisolarians did not care about humans surpassing themselves as you mentioned the Sophons were already locking out their basic sciences. They were only worried about humans discovering the deterrent.

The show changed a few characteristics about the Trisolarians to make it seem much weaker than they should be. They are traveling at 1% light speed in the show! In the books, they were already reaching 10% light speed at that point.

They are traveling at 1% light speed in the show! In the books, they were already reaching 10% light speed at that point.

Technically their whole journey is at 1% light speed in the books, accounting for acceleration and deceleration - they take ~400 years to go 4 light years. I guess the show just couldn't be bothered to explain the mechanics of it.

Yes, that’s true, but by forgoing this detail in the show, there are consequences in how to explain some of the later events.
