Contributions To Stellar Statistics. First Paper. On The Position Of The Galactic And Other Principal Planes Toward Which The Stars Tend To Crowd

1904039055Washington: The Carnegie Institution 1904. 1st Edition 1st Printing. Soft cover. Very Good. 32 Pp. Quarter Red Cloth Handwritten Short Title On Spine Over Light Green Paper Boards Printed In Black. Wear At Corners Paper Tips Frayed Bookplate Of Dartmouth Mathematics Professor Charles Nelson Harkins. 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 Starting Development 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 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.I N 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. <br/> <br/> The Carnegie Institution paperback

Abbot Went From Being Director Of The Smithsonian Astrophysical Observatory To Becoming Assistant Secretary And Then Secretary Of The Smithsonian Institution Over The Course Of His Career. As An Astrophysicist He Researched The Solar Constant Research That Led Him To Invent The Solar Cooker Solar Boiler Solar Still And Other Patented Solar Energy Inventions. While At The Smithsonian Astrophysical Observatory Sao Abbot Would Work Under Samuel P. Langley. Langley Would Go On To Change His Focus From Solar Radiation To Aeronautics With Abbot Taking Over Solar Radiation Research. Abbot Would Participate In Many Expeditions. In 1900 He Along With Langley Would Travel To Wadesboro North Carolina To Observe A Solar Eclipse Followed By Another Eclipse Expedition To Sumatra In 1901. During His Expedition Experiences He Would Also Travel To Algeria Egypt South Africa Australia And Other Countries Often In Partnership With The National Geographic Society. Abbot Would Become Acting Director Of Sao In 1906 And In 1907 Abbot Became The Director Of The Smithsonian Astrophysical Observatory Following The Death Of Samuel P. Langley. While Langley Was Still Director He Had Visited Mount Whitney And Decided It Would Be A Great Place For An Observatory. Abbot Secured Funding For The Observatory And It Was Built In 1909. As Director A Position He Would Hold Until His Retirement Abbot Would Open The Radiation Biology Laboratory In 1929 To Study Radiation Effects On Plants And Other Organisms. This Helped To Develop The First Wave Of Biophysics Researchers In The United States. <br/> <br/> Smithsonian Institution hardcover
