From Stars By A. S. Eddington
By mathematical methods it is possible to work out how fast the pressure increases as we go down into the sun, and how fast the temperature must increase to withstand the pressure. The architect can work out the stresses inside

the piers of his building; he does not need to bore holes in them. Likewise the astronomer can work out the stress or Perhaps its more surprising hat it temperature cal be found by pure calculation. It is natural that you should feel
10. rather skeptical about our claim that we know how hot it is
12. skeptica when l divuge the actual figures Thererore had
13. better describe the method as far as I can. I shall not
14. attempt to go into detail, but I hope to show you that there
15. is a clue, which might be followed up by appropriate
16. mathematical methods.
