[PAR] [TLE] Arthur Eddington [SEP] Sir Arthur Stanley Eddington (28 December 1882 – 22 November 1944) was an English astronomer, physicist, and mathematician of the early 20th century who did his greatest work in astrophysics.  He was also a philosopher of science and a populariser of science.  The Eddington limit, the natural limit to the luminosity of stars, or the radiation generated by accretion onto a compact object, is named in his honour. [PAR] [TLE] Eddington number [SEP] In astrophysics, the Eddington number, "N", is the number of protons in the observable universe.  The term honors the British astrophysicist Arthur Eddington, who in 1938 was the first to propose a value of "N" and to explain why this number might be important for physical cosmology and the foundations of physics.
