H. Pierre Noyes (born December 10, 1923[1]) is an American nuclear physicist. He has been a member of the faculty at the SLAC National Accelerator Laboratory at Stanford University since 1962.[2] Noyes specialized in several areas of research, including the relativistic few-body problem in nuclear and particle physics; foundations of physics; combinatorial hierarchy; and bit-string physics: a discrete model for masses, coupling constants, and cosmology from first principles.[2]

Biography

H. Pierre Noyes was born in 1923 in Paris, France to the American chemist William Albert Noyes, Sr. and Katherine Macy, daughter of Jesse Macy. His older half-brothers were W. Albert Noyes, Jr. and Richard Macy Noyes who both became chemists.

Education

Noyes received his baccalaureate degree in physics (magna cum laude) in 1943 from Harvard University.[2] One of his roommates during this time was Thomas Kuhn, author of The Structure of Scientific Revolutions. Before moving on to doctoral studies, Noyes spent a year at the Antenna Group at the MIT Radiation Laboratory and served in the US Navy for two years as an Aviation Electronics Technician Mate.[3]

Noyes earned his Ph.D. in theoretical physics from the University of California at Berkeley in 1950[2] doing research under the direction of Robert Serber with Geoffrey Chew as his advisor. Noyes’ first doctoral problem was pion-pion scattering, followed by a second problem: meson production from proton-deuteron decay. His work under Chew was among the early applications of S-matrix theory.[3]

After earning his Ph.D., Noyes spent a postdoctoral year on a Fulbright scholarship at the University of Birmingham, England,[2] under the direction of Rudolf Peierls.[3]

Career

Noyes’ career included several academic and research positions. He first worked as a post-doctoral fellow and then as assistant professor of Physics at the University of Rochester (1952–5).[2] During that time, he compiled and edited the Proceedings of the 2nd, 3rd, 4th, and 5th Rochester Conferences on High Energy Physics. During the summers of those years, he worked at Project Matterhorn at Princeton, researching thermonuclear weapons (1952) and at the Brookhaven National Laboratory (1953). During the summer of 1954, he worked on calculating the binding energy of the triton using a particular non-relativistic, quantum mechanical potential model fitted to the low energy nucleon-nucleon parameters at the Lawrence Berkeley National Laboratory in Berkeley, California.[3]

In 1955, Noyes joined the Theoretical Division of what was to become the Lawrence Livermore National Laboratory. From 1956 to 1962, he served there as group leader of the General Research Group,[2] under co-founder and director Edward Teller. During that time, he also served as co-chair of the design-review pre-mortem committee for the devices tested on Christmas Island in 1962 during Operation Dominic I, including the UGM-27 Polaris submarine-launched ballistic missile and Minuteman II intercontinental ballistic missile (ICBM) warhead prototypes.[3]

During a sabbatical from his work at Lawrence Livermore in 1957 and 1958, Noyes was Leverhulme Trust Lecturer in the Experimental Physics Department of the University of Liverpool. He also worked as a consultant to General Atomics under Freeman Dyson and Ted Taylor for Project Orion[2] (a nuclear explosion propelled space ship) from 1958 to 1961 at the invitation of Prof. Dyson.[3]

In 1961, Noyes served as AVCO visiting professor at Cornell University.[2]

Starting in 1962, he worked at SLAC as head of theoretical physics until he was replaced by Sidney Drell (who combined that responsibility with being Deputy Director of SLAC). He progressed from associate professor from 1962 through 1967 to professor (at SLAC, 1967–2002) and was awarded emeritus status in that rank on May 1, 2000.[2] He collaborated with Richard Shoup at the Boundary Institute.[4]

Noyes served as the Associate Editor of the Annual Reviews of Nuclear Science from 1962 until 1977.[5] In 1979 he received an Alexander von Humboldt U.S. Senior Scientist Award, primarily to continue his theoretical work on the quantum mechanical three body problem for strongly interacting particles. In that same year he joined with John Amson, Ted Bastin, Clive W. Kilmister and A. Fredrick Parker-Rhodes to found the Alternative Natural Philosophy Association (ANPA), and was president of that organization until 1987.[3][6]

Research

In his early career, Noyes primarily focused on nuclear forces from an elementary particle point of view. In Inward Bound, Abraham Pais had commented, correctly, that no one's work along this line lead to any fundamental new insights into elementary particle theory. Noyes’ research into this area confirmed that the phenomenological analysis of nucleon-nucleon and pion-nucleon scattering, supplemented by an S-matrix based dispersion theory, shows that quantum field theory is roughly correct for two-particle scattering, and in some cases can be connected to the non-relativistic models used in nuclear physics. The research did not, however, lead to any unique, quantitative model of the strong interactions.[3]

After leaving Lawrence Livermore Laboratory, he started working on the quantum mechanical three body problem developed by Ludvig Faddeev, Alt, Grassberger, and Sandhas by reformulating it in the relativistic domain. In 1969, he concluded that any nonreletivistic quantum mechanical three body problem using strictly finite range forces between the pairs necessarily implies a non-local interaction in any three body system, which would extend to indefinitely large distances. A specific example of this is the fact that three identical particles with scattering lengths between the pairs that tend toward infinity, will support an indefinitely large number of three body bound states with their radii increasing as the square of that number, as was shown independently by Vitaly Efimov in a specific model.[3]

Driven by this success, an interest in John Stewart Bell’s work, and Thomas Phipps’ construction of a covering theory for both classical and quantum mechanics, Noyes was inspired to return his attention to the foundations of quantum mechanics. Around this time (1972-3), he heard a report from Ted Bastin on his combinatorial hierarchy work and met with Bastin and his collaborators: J. C. Amson, C. W. Kilmister, and A. F. Parker Rhodes. The research conducted during this interaction resulted in the development of and many papers on finite and discrete physics and cosmology called bit-string physics.[7] This work became Noyes’ focus for much of the rest of the century. His contributions to the new field include:[3]

of \hbar c / e^2 = 137 given by the first three levels of the combinatorial hierarchy could be given physical interpretation as the maximum number of electron-positron pairs which could be discussed within a radius of \hbar / 2 m_e c, using renormalized quantum electrodynamics. Further, the rest energy of this system (137 \times (2 m_e c^2)) \simeq m_\pi c^2 could then suggest that the breakdown of quantum electrodynamics found by Dyson might be due to the strong interactions mediated by pions. The same argument extended to the fourth level suggested that the closure of the scheme at the fourth level, characterized by 2^{127}, could be understood as the formation of a black hole with the Planck mass by that number of baryons of protonic mass concentrated within \hbar / m_p c. Noyes, however, remained profoundly skeptical of these results until a decade later when David McGoveran showed that the scheme not only allowed one to derive the Sommerfeld-Dirac formula for the fine structure spectrum of hydrogen and then to correct the 137 approximation by correctly calculating the next four significant figures in the inverse fine-structure constant in agreement with experiment, but also to correct the value for Newton's gravitational constant and compute several other elementary particle coupling constants and mass ratios.

Some of his letters to Gregory Breit (1899–1981) are in the collection of the Yale University Library.[9]
