Henri Poincare

4/29/1854 - 7/17/1912

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).

Bertrand Russell

Kurt Gödel

4/28/1906 - 1/14/1978

Tom Apostol

Events

Rhind Mathematical Papyrus

1650 B.C.

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).

Library of Alexandria

284 B.C.

Alexandria, Egypt. It was destroyed between 48 B.C. and around 600 A.D. --- we aren't sure how exactly it was destroyed, but there are varying accounts during this time documenting it

Versorium

1600

First electric measuring instrument, a versorium (Latin for "turn around") was a crude electroscope.

Galileo's Mechanics

1623

Newton's Principia Mathematica

07/05/1687

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.

Coulomb's Law

1785

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).

Decimal Metric System

06/22/1799

Created in France at the time of the French Revolution. These were the precursors of the SI system

Young's double-slit experiment

1803

Ohm's Law

1827

Faraday Cage

1836

Kirchoff's Laws

1845

Maxwell's equations

1865

Published in his paper "A Dynamical Theory of the Electromagnetic Field"

Mendeleev's first periodic table

1869

A Treatise of Electricity and Magnetism

1873

Maxwell's multi-volume treatment of EM

CGS System

1874

Introduced by the British Association for the Advancement of Science (BAAS) under leadership of Maxwell and Thomson. CGS was based on centimeter, gram, and second, with associated 103 prefixes.

Michelson Interferometer

1887

MKS System

1889

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).

Electron discovered

1897

JJ Thompson Discovered the electron while working on cathode ray tubes and created the "Plum Pudding Model" for atoms.

Einstein's photoelectric effect

06/09/1905

Einstein's special relativity

09/26/1905

Einstein's E=mc^2

11/21/1905

Robert Millikan Oil Drop Experiment

1910

Determined the elementary charge.

von Laue x-ray diffraction

1912

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.

Bohr atomic model

1913

Compton scattering

05/1923

De Broglie wavelengths

1924

Schrodinger's Equation

1926

Heisenberg principle

3/01/1927

Van de Graaff Generator

1929

MKSA System

1946

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.

MKSAKCm SI system

1971

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).

Carl Sagan's "Cosmos"

09/20/1980

Physicists

Aristotle

384 b.c. - 322 b.c.

William Gilbert

05/24/1544 - 11/30/1603

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.

Galileo Galilei

2/15/1564 - 1/8/1642

Isaac Newton

12/25/1642 - 3/20/1727

Benjamin Franklin

1706 - 1790

"Discovered" electricity, dubbed "positive" and "negative"

Charles Coulomb

1736 - 1806

In 1784 used that balancing experiment much like was used for gravity to determine the force between point charges. It was analogous to Newton's law of gravitation, where the force was inversely proportional to the distance squared and the charges.

Michael Faraday

09/22/1791 - 08/25/1867

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.

Lord William Kelvin

06/26/1824 - 12/17/1907
