Simon Newcomb (1835 -1909) Was A Canadian-American Astronomer, Applied Mathematician And Autodidactic Polymath. Newcomb Visited Paris, France In 1870, Already Aware That The Table Of Lunar Positions Calculated By Peter Andreas Hansen Was In Error. While In Paris, He Realized That, In Addition To The Data From 1750 To 1838 That Hansen Had Used, There Was Further Data Stretching As Far Back As 1672, And Newcomb Used The "New" Data To Revise Hansen's Tables. In 1878, Newcomb Started Planning For A New And Precise Measurement Of The Speed Of Light, Using A Refinement Of The Method Of Léon Foucault. A Letter From Albert Abraham Michelson Began A Long Collaboration And Friendship. In 1880, Michelson Assisted At Newcomb's Initial Measurement, But Michelson Left To Start His Own Project. Miichelson Published His First Measurement In 1880 (Reprinted Here), But Newcomb's Measurement Was Substantially Different, And, In 1883, Michelson Revised His Measurement To A Value Closer To Newcomb's. In 1881, Newcomb Discovered The Statistical Principle Now Known As Benford's Law, Formulating The Principle That, In Any List Of Numbers Taken From An Arbitrary Set Of Data, More Numbers Will Tend To Begin With "1" Than With Any Other Digit. In 1891, Within Months Of Seth Carlo Chandler's Discovery Of The 14-Month Variation Of Latitude, Now Referred To As The Chandler Wobble, Newcomb Explained The Apparent Conflict Between The Observed Motion And Predicted Period Of The Wobble, As Due To Elasticiity; He Used The Variation Of Latitude Observations To Estimate The Elasticity Of Earth, Finding It To Be Slightly More Rigid Than Steel. He Wrote On Economics And His Principles Of Political Economy (1885) Was Described By John Maynard Keynes As "One Of Those Original Works Which A Fresh Scientific Mind, Not Perverted By Having Read Too Much Of The Orthodox Stuff, Is Able To Produce From Time To Time In A Half-Formed Subject Like Economics." He Was Credited By Irving Fisher With The First-Known Enunciation Of The Equation Of Exchange Between Money And Goods Used In The Quantity Theory Of Money. His Reputation Suffers From His Hostility To C. S. Pierce, And Also From Newcomb's Disbelief In The Possibility Of Manned Flight. (Source: Wikipedia). Albert A. Michelson (1852-1931) Performed Early Measurements Of The Velocity Of Light With Amazing Delicacy And In 1881 He Invented His Interferometer For The Purpose Of Discovering The Effect Of The Earth's Motion On The Observed Velocity. In Cooperation With Professor E.W. Morley, And Using The Interferometer, It Was Shown That Light Travels At A Constant Speed In All Inertial Systems Of Reference. The Instrument Also Enabled Distances To Be Measured With Greater Accuracy By Means Of The Length Of Light-Waves. At The Request Of The International Committee Of Weights And Measures, Michelson Measured The Standard Metre In Terms Of Wavelength Of Cadmium Light. He Invented The Echelon Spectroscope And During His Wartime Service In The Navy He Performed Research Work On Devices For Naval Use - He Developed A Rangefinder Which Was Adapted As Part Of U.S. Navy Equipment. On His Return To Civilian Life, Michelson Became More Interested In Astronomy And In 1920, Using Light Interference And A Highly Developed Version Of His Earlier Instrument, He Measured The Diameter Of The Star Betelgeuse: This Was The First Determination Of The Size Of A Star That Could Be Regarded As Accurate. He Was The First American To Receive The Nobel Priize For Physics. (Nobel Lectures, Physics 1901-1921, Elsevier Publishing Company, Amsterdam, 1967).
