This article does an amazing job of describing the various versions of the definition of "time" used in physics. The author limits his use of jargon, but defines them well when necessary. Highly recommended.
- iaw 12y agoI wonder if the statement about Newton's second law (there exists an r(-t)) holds true when you include relativistic effects.
