Believed in the power of intuition over logic as mathematical understanding (contrary to those as Russell). Bounced around off problems, discovered him through vector analysis (via his assessment of Stokes' Theorems' relation to calculus). Apparently he described relativity mathematically via Lorentz transformations before 1905 (ie "Ars Magna", when Einstein published his papers).

A fantastic source of information on Egyptian mathematics. There is some contention in this date - Boyer says possibly more like 4000 B.C. Talks about 2/p fraction decomposition into unit fractions (didn't seem to grasp general fractions).

Three books in Latin detailing Newton's laws and deriving Kepler's Laws, along with deriving infinitesimal calculus (apparently Newton and Leibniz had a bit of a battle in who invented calculus)? It was a landmark work that set the standard for science to come.

The torsion balance experiment used to derive the inverse square relationship of force to distance between charges. This setup is much the same as that used to determine the force of gravity (though those forces were much weaker).

The "Metre Convention" in 1875 created the BIPM (the Bereau International des Poids et Measures, or in English, the International Bureau of Weights and Measures, which exists today to oversee the SI units). BIPM is in France. The MKS system was meters, kg, and second. BIPM exists under the authority of the General Conference on Weights and Measures (CGPM, Conference Generale des Poids et Mesures), which meets every 4 years to discuss the happenings of CIPM.
Also established from the Meter Convention was the CIPM (Committee for Weights and Measures), which consists of 18 individuals from different countries (this is starting to sound like the IETF structure).

X-rays, produced first by Rontgen in 1895, were shined into a crystalline solid, producing a diffraction pattern, creating a method of mapping atomic structures. It also shed light on the x-ray wavelength.

With an added unit of electrical nature, the ampere (either the ampere or ohm would've worked, as shown by Gorgio in 1901), electrical units could be expressed as derived SI units, so the ampere was added.

After the addition of Ampere to the SI base units in 1946 and the kelvin and candela in 1954, the mole was added in 1971, following discussions between chemists and physicists at the CGPM conference for weights and measures. This is the current form of our SI base units (meter, kilometer, second, ampere, candela, kelvin, mole).

An English physicist regarded as one of the "fathers" of electricity. He invented the electroscope (basically an electrostatic compass) and coined the term "electricus" from the Latin word for "like amber", from which "electricity" was derived.

English scientist, contributed to electromagnetism for Maxwell to run with (Faraday didn't have much of a math background). Discovered EM fields and realized they could affect light (thus were the same phenomena). Developed field lines.
