Which is also missed by most of popularisations, and unfortunately a lot of physicists.

See my post #2 about a more modern interpretation. In an inertial frame of reference an object obeys Newton's first law. The danger, as...

Interesting article about Newton's first law...

OK. So you really are interested in what Newton said. But please don't use what he said as anything that contradicts modern statements...

Thanks!

I think you've missed the point of the thought experiment.

I’d venture that this is unanswerable and not an object of scientific pursuit. Had you asked “how,” perhaps something could be said. But...

I agree. They are subtly different, I would say.

How are they "very different", if the difference has zero impact on the quantitative predictions?

That's the sort of thing that happens on IT projects!

See post #2 where I said: It doesn't matter whether you start with "Young and Randall" or start with "Serway". You end up with the...

It's not necessarily the one-way speed, but it is necessarily the two-way speed of light. What your maths tells you, in short, is that...

The motion of the planets relies on the gravitational force to keep them in an elliptical orbit. The point that Newton is making is that...

The 3 body problem was the first example on which people became aware of what dynamical chaos is. The effect of separatrices...

Oh, it's definitely solvable, and we know how to solve it. So your conclusion is correct, but I don't see how it follows from your...
