WebScience has given us such colossi as Avogadro's number (the number of molecules in a sample whose weight in grams equals its molecular weight) = 6.023 × 10 23, the Eddington number (astrophysicist Arthur Eddington's best estimate of the number of protons in the universe) = 1.575 × 10 79, and the Supermassive Black Hole Evaporation Time = 10 ... In astrophysics, the Eddington number, NEdd, is the number of protons in the observable universe. Eddington originally calculated it as about 1.57×10 ; current estimates make it approximately 10 . The term is named for British astrophysicist Arthur Eddington, who in 1940 was the first to propose a value of … See more Eddington argued that the value of the fine-structure constant, α, could be obtained by pure deduction. He related α to the Eddington number, which was his estimate of the number of protons in the universe. This led him in … See more The most precise value of α (obtained experimentally in 2012) is: $${\displaystyle \alpha ^{-1}=137.035\,999\,174(35).}$$ Consequently, no … See more • John D.

WebSep 28, 2024 · Your Eddington number is defined as the largest integer E, where you have cycled at least E miles on at least E days. For example an E of 60 means that you have ridden 60 miles or more on 60 or more days. Simple. WebJan 26, 2024 · The Eddington number (E-number) for cycling is defined as the largest number E, where you have cycled at least E kilometers / miles on at least E days.

WebThe Eddington number in the context of cycling is defined as the maximum number E such that the cyclist has cycled E miles on E days. For example, an Eddington number of 70 would imply that the cyclist has cycled at least 70 miles in a day on 70 occasions. Achieving a high Eddington number is difficult since moving from, say, 70 to 75 will ...
