Cavendish Laboratory : Letter from Faraday to Maxwell 1857
Cavendish Laboratory
<p style='text-align: justify;'>A response to the letter from Maxwell of 9 November 1857 (P.M. Harman, 'The scientific setters and papers of J.C. Maxwell', CUP 1990, vol.1 pp. 548-552), in which Maxwell urged a clearer distinction be drawn between conservation of energy and conservation of force. Maxwell also explained why Faraday's idea of field lines can be applied to gravity and proposed the use of a mathematical formalism for further investigation of the phenomenon. This photograph was probably taken on the occasion of the Maxwell Centenary Celebrations in 1931.</p>
