Physics did not begin in London in 1686. It began 2 centuries later in 1874 in Kristiania.

1686 was Newton, but 1874 was Lie.

Aaa, 1686 was what? Principia was published in 1687. And 1874 is the birth year of Sophus Lie, right?

Oh, the irony/controversy.

It might be the final manuscript date vs. the publication year.

I had no idea Samuel Pepys was involved. Whaddaya know.

Maybe, it could be summarized as: Newton found the equations, and Lie established the invariants.
