| Title | Letter from Ernest W [William] Brown, 116 Everit Street, Yale University, New Haven, to [Joseph] Larmor |
| Creator | Brown; Ernest William (1866-1938); British mathematician and astronomer |
| Date | 20 January 1915 |
| Description | He has been trying to make Larmor's first hypothesis look reasonable, but he 'sticks' near the foot of page 4 of Larmor's paper. He agrees with Larmor reasoning on the rate of Earth's rotation. The Moon is less effective in showing the error of the Earth as a clock and he comments on the minor changes in the Moon's longitude. By Larmor's hypothesis it would require a fall of 750 feet in a year, outside the range of probability. Minor changes in the Moon's longitude cannot be attributed to this cause. The hypothesis may be different for slow long continued changes. He has not been over the frictional part in detail yet. There are few German sympathisers at Yale, conditions are more or less normal, with much unemployment. In a postscript, he comments that evidence for big changes such as those mentioned in South America is doubtful, as is their age. |
