- 14 Mass - Luminosity relation
- 15 Mass - Luminosity relation calculated by Eddington
- 16 Luminosity of a star depends only on its mass!
- 17 Why are the stars as they are?
- 18 To Eddington this 'agreement' was most annoying! "What business have they on a curve reserved for a perfect gas?", he exclaimed.
- 19 "Our mistake was that in estimating the congestion in the stellar ball-room we had forgotten that crinolines are no longer infashion" - Eddington
