| Title | Letter from M J M [Micaiah John Muller] Hill, 18 Ferncroft Avenue, Hampstead, London, to [Joseph] Larmor |

| Recipient | Larmor; Sir Joseph (1857-1942); Irish theoretical physicist |

| Description | The rejection of M. [Michael] Foster by the University is 'a deadly blow'. [Philip] Magnus is a promoter of the scheme for a new independent technical college in South Kensington and this is contrary to the University Act, and the setting up one directing body. Foster has offended the medicine men, Hill believes, in not nursing his constituency. Hill returns the work that Larmor sent him, his thinking commencing with his spherical vortex paper. This gave some rotational solutions to the equations of fluid motion and Hill discusses his work from that point in detail. He thinks that of relation between the vorticity and the velocity along its axis of the vortex, which would hold good for the spherical vortex and the annular vortex. His problem now is having solved the hydrodynamical equatations inside a finite portion of space, 'can we throw awy the rotational motion outside it & replace it by irrotational motion'. He has had this idea for years but has failed to take the next step. In a postscript, he discusses his double integrals and their implications. |
