The Sir John Herschel Collection
The preparation of the print Calendar of the Correspondence of Sir John Herschel (Michael J. Crowe ed., David R. Dyck and James J. Kevin assoc. eds, Cambridge, England: Cambridge Univ. Press, 1998, viii + 828 pp) which was funded by the National Science Foundation, took ten years. It was accomplished by a team of seventeen professors, visiting scholars, graduate students, advanced undergraduates, and staff working at the University of Notre Dame.
The first online version of Calendar was created in 2009 by Dr Marvin Bolt and Steven Lucy, working at the Webster Institute of the Adler Planetarium, and it is that data that has now been reformatted for incorporation into Ɛpsilon.
Further information about Herschel, his correspondence, and the editorial method is available online here: http://historydb.adlerplanetarium.org/herschel/?p=intro
No texts of Herschel’s letters are currently available through Ɛpsilon.
Miss Caroline Herschel has just been elected an honorary member of the Academy. How shall they forward the diploma?
Sends copies of three letters by G. B. Airy on proposed railway through Greenwich Park. Asks JH's opinion on possible effects on observatory.
Expresses views on nature of exponential functions and defines terms that may have caused confusion in [J. T.] Graves's paper, which JH found unsatisfactory. Requests JH's reply.
Wants WH's quaternion mathematics to be challenged; also worries that quaternions will become merely 'a private and personal skill' instead of a method that can be taught.
Describes the funeral of James MacCullagh; mystified why he committed suicide.
Thrilled by JH's encouragement concerning WH's 'Theory of Systems of Rays.' Enthusiastic about his career prospects at the University of Dublin.
Sorry that he could not meet JH when JH was in Dublin; hopes to be introduced to JH soon. Answers JH's queries about WH's work; explains that he is studying 'the general properties of systems of rays, and of the surfaces with which they are connected.'
Rev. Humphrey Lloyd's paper on conical refraction agreed with WH's conclusions.
Encouraged that a calculus can be constructed out of his exponential series findings.
Sorry to hear that JH was not elected President of the R.S.L. Sending a supplement to WH's 'Theory of Systems of Rays' essay. Recommends [Edwin Richard Windham Wyndham-Quin,] Lord Adare for consideration as a member of the R.A.S.
Developed a method that greatly simplifies Joseph Lagrange's integration of the 3n differential equations of motion of the second order by reducing all calculations to the application of 'one principal function.' Applies the method to planetary motion.
Congratulates JH on his successful Cape Town enterprise.
Pleased that the Royal Irish Academy awarded its Science Medal to James MacCullagh for his paper on the "Laws of Crystalline Reflexion and Refraction;" he deems MacCullagh's essay superior to WH's "On Algebra as the Science of Pure Time.","L
Asks JH to keep him updated on English research of the dynamics of light. Currently considering the 'propagation' of light waves, as distinguished from their mere 'preservation'; asks whether this is a new study.
Considering motion as a 'successive excitement of powers.'
Confides that the past year has been 'a sombre one ... but not unhappy.'
Thanks JH for JH's translation of Friederich Schiller's poem 'The Walk.'
Jokes about WH's recent 'astronomical insignificance.'
Elated that WH's account of the generation of an ellipsoid is an original result.
Sends some new theorems concerning undisturbed parabolic motion; believes that much remains to be discovered in this field.
