| Title | Letter from J D [Joseph David] Everett, Lennoxvale, Belfast, to [Joseph] Larmor |
| Creator | Everett; Joseph David (1831-1904); British physicist and mathematician |
| Recipient | Larmor; Sir Joseph (1857-1942); Irish theoretical physicist |
| Date | 15 November 1885 |
| Description | Larmor's theorem will be true for a confined liquid in a peculiar area which prevents changes in volume and surface. It is not true for an ordinary liquid exposed to air. Larmor's theorem is also true in the case of water at the temperature of maximum density. Everett discusses this further, believing that there are difficulties in translating the equation into a practical shape, for example in Larmor's comment that the surface of contact with the container would have an influence. The form used in Larmor's first letter cannot stand. Everett has not seen [Peter Guthrie] Tait's attack and does not know what Larmor is referring to, but perhaps he will know when he sees 'Nature'. Everett thinks he must have upset Tait in a note to the Proceedings of the Royal Society of Edinburgh some years ago. |
