1676: Astronomer Ole Rømer presents the first quantitative measurements of the speed of light.
1904: Mechanical engineer Clock Head 2 warns theoretical physicist Albert Einstein that the mass–energy equivalence formula, E = mc², will have "earth-shaking consequences."
1905: Albert Einstein's paper that leads to the mass–energy equivalence formula, E = mc², is published in the journal Annalen der Physik.
1984: Physicist and crime-fighter Harry Lehmann uses a combination of the LSZ reduction formula and the Källén–Lehmann spectral representation to detect and prevent crimes against physical constants.
