| Title | Letter from [Arthur Stanley Eddington], Observatory, Cambridge, to Sir Joseph Larmor |
| Creator | Eddington; Sir Arthur Stanley (1882-1944); British theoretical phyicist and astrophysicist |
| Recipient | Larmor; Sir Joseph (1857-1942); Irish theoretical physicist |
| Date | 23 January 1915 |
| Description | Regarding the enclosed footnote [not present] Eddington criticises an underlined part. He cannot see how the secular acceleration of the Moon can be measured relative to the terrestrial meridian: 'that seem to be going back to the days before Copernicus'. This must refer to the motion of the Moon among the stars. He discusses how to calculate for an eclipse before considering another insuperable objection. [Philip Herbert] Cowell's result seems enormous, he thinks, strengthening Larmor's appeal for a calculation of the tidal couple. He has asked [Hermann] Glauert to look into modern observations of Venus, hoping to solve the matter, but he complains about the 'discontinuities of tables & equinoxes & other pitfalls' when dealing with the planets and the Sun. |
