Trained as a physical chemist and theoretical nuclear physicist, he is the co-author with Pierre Marmier of the widely used multi-volume textbook ''Physics of Nuclei and Particles'', and in later years turned to questions in relativity and cosmology — most notably a re-examination of the relativistic twin paradox that questioned how the standard textbook treatment is presented and taught.

	~~Emeritus Professor of Physics and Applied Physics, Honors Director Emeritus~~		== Biography ==

	~~'''Visiting Professorships:'''~~		=== Early life and education ===
			Sheldon was born in Pilsen, Bohemia, and was educated in England, at Pinner Park Elementary School and Harrow County School in London. He read physics at the University of London, taking a B.Sc. (General) in physics, chemistry and mathematics followed by a B.Sc. (Special) in physics with honours in 1952, and a Ph.D. in 1955. He afterwards studied and worked at the Swiss Federal Institute of Technology (ETH Zurich) and the University of Zurich, and was later awarded the higher doctorate of D.Sc. by London.

	~~1968-69: University~~ of ~~Virginia in Charlottesville<br />1969~~-~~70: University of Texas~~ in ~~Austin<br />1989: University~~ of ~~Oxford <br /><br />'''Education:'''~~		=== Academic career ===
			Sheldon's early research was in physical chemistry — electrochemistry and thermodynamics — including work with J. O'M. Bockris on the mechanism of the hydrogen evolution reaction on metal electrodes under high-purity conditions. He then moved into theoretical nuclear physics and nuclear astrophysics, and it is in that field that most of his refereed output lies.

	~~Pinner Park Elementary School~~, ~~London <br />Harrow County School, London <br />University of London <br />Swiss Federal Institute of Technology (ETH-Zurich) <br />University~~ of ~~Zurich~~		He joined Lowell Technological Institute in 1970, continuing through the institution's successive changes of name:

	~~'''Academic Degrees~~:~~'''~~		* 1970–73: Lowell Technological Institute
			* 1973–91: University of Lowell
			* 1985–88: University Professor, University of Lowell
			* 1991–96: University of Massachusetts Lowell
			* 1994–96: Honors Director, University of Massachusetts Lowell

	~~B.Sc.(General:~~ Physics~~, Chemistry, Mathematics)<br />B.Sc.(Special~~ Physics, ~~Honours)<br />Ph.D. (Science)~~, ~~D.Sc~~. ~~[London]~~		He retired in 1996 as Emeritus Professor of Physics and Applied Physics and Honors Director Emeritus, and subsequently settled in Oxford, England.

	~~'''Learned Societies:'''~~		He held visiting professorships at the University of Virginia at Charlottesville (1968–69), the University of Texas at Austin (1969–70), and the University of Oxford (1989). Since 2000 he has been an Academy Visitor at the University of Oxford.

	''~~'Professional Qualifications:'~~''		=== Nuclear physics ===
			With Pierre Marmier of ETH Zurich, Sheldon wrote ''Physics of Nuclei and Particles'' (Academic Press, 1969–70), a comprehensive graduate text issued in multiple volumes covering nuclear constituents and interactions, nuclear forces and potentials, scattering and reaction models, nuclear models, nuclear matter and elementary particles. The work remained a standard reference for many years and is still in print in electronic editions.

	~~Chartered Chemist (C~~.~~Chem~~.), ~~Chartered Physicist (~~C.~~Phys~~.)		His review article with D. M. Van Patter, "Compound inelastic nucleon and gamma-ray angular distributions for even- and odd-mass nuclei" (''Reviews of Modern Physics'', 1966), became a much-cited reference for compound-nucleus reaction analysis, and he later collaborated with V. C. Rogers on computational codes for nuclear reaction calculations published through ''Computer Physics Communications''. He also collaborated on the English edition of Wildermuth and Tang's ''A Unified Theory of the Nucleus''.

	'''~~Research~~ and ~~Other Interests~~:~~'''~~		=== Relativity and the twin paradox ===
			In retirement Sheldon returned to foundational questions in relativity. In "Relativistic Twins or Sextuplets?" (''European Journal of Physics'', 2003) he revisited the classic twin paradox and argued that the usual textbook treatment — a single travelling twin on constant-velocity legs — conceals as much as it reveals. He set out two contrasting scenarios: one built from constant-velocity segments, and an alternative mission flown with sustained acceleration and deceleration, worked through for a two-way spacecraft flight from Earth to Polaris. By multiplying the number of observers, he showed that the accounting of elapsed proper time is considerably less straightforward than the standard presentation suggests, and that the asymmetry usually attributed simply to "the one who turns around" requires more careful justification than it is normally given.

	~~Physical Chemistry (Electrochemistry~~, ~~Thermodynamics); Theoretical nuclear physics and nuclear astrophysics; Astronomy and astrophysics; Relativity~~ and ~~cosmology~~.		The paper is representative of a line of work by physicists inside the mainstream who accept the formalism of special relativity but object to how casually its paradoxes are dispatched in teaching. It has been cited in subsequent discussions of simultaneity and retarded aging in special relativity, and remains a reference point in the literature on the twin paradox.
