In 2019, Larry Griffing, an affiliate professor in Biology at Texas A&M College, proposed that a portrait by Mary Beale of the not known sitter and called Portrait of the Mathematician – is really of Hooke, noting the Bodily functions from the sitter inside the portrait match Hooke's. The determine factors to a drawing of elliptical movement that appears to match an unpublished manuscript designed by him. The painting also incorporates an orrery depicting the exact same principle. Based on Griffing, buildings included in the picture are of Lowther Castle, now in Cumbria, and its Church of St Michael.

Hooke's statements around 1674 make no mention, on the other hand, that an inverse sq. law applies or might utilize to these points of interest. His product of gravitation was also not however universal, nevertheless it approached universality much more closely than former hypotheses.[117] Hooke didn't supply accompanying proof or mathematical demonstration; he stated in 1674: "Now what these a number of degrees [of gravitational attraction] are I have not yet experimentally confirmed", indicating he didn't nevertheless really know what law the gravitation could possibly adhere to; and about his total proposal, he explained: "This I only trace At this time .
