SUMMARY

The significance of PF signatures in historical physics debates centers around the contrasting contributions of Isaac Newton and Sophus Lie. Newton's work, particularly the publication of "Principia" in 1687, laid the foundation for classical mechanics, while Lie's birth in 1874 marks a pivotal moment in the development of modern mathematical physics through the establishment of Lie groups and invariants. This discussion highlights the irony in the timeline of physics development, emphasizing that the field's evolution extends beyond its traditional milestones.

PREREQUISITES
  • Understanding of classical mechanics and Newtonian physics
  • Familiarity with the concept of Lie groups in mathematics
  • Knowledge of historical context surrounding the publication of "Principia"
  • Awareness of the contributions of key figures in physics history
NEXT STEPS
  • Research the impact of Lie groups on modern physics
  • Study the historical significance of Newton's "Principia" and its influence on science
  • Explore the role of mathematical structures in physics, particularly invariants
  • Investigate the contributions of other key figures in the development of physics post-Newton
USEFUL FOR

Historians of science, physicists interested in the evolution of mathematical physics, and students studying the foundational figures in physics will benefit from this discussion.

Physics did not begin in London in 1686. It began 2 centuries later in 1874 in Kristiania.
@fresh_42 Sorry for the blatant off-topic, please explain this text in your signature. Thanks!

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.
