Contact seller5-star seller1st Edition. FIRST EDITION, RARE OFFPRINT OF BONDI ON GRAVITATIONAL BOUNCE IN GENERAL RELATIVITY. Hermann Bondi discusses the adiabatic collapse solutions of uniform density spheres under differing assumptions regarding density and central pressure. In discussing the problem of collapse and bounce, Bondi made two assumptions: ìf…irst, that the motion is isotropic or shear-free; and second, that the density is uniformî (Durgapal, On Collapse of Uniform Density Sphere with Pressure, JMP, 2010, 143). Bondi examined the radial motion of uniform spheres in general relativity, concluding that in certain cases the system would ìbounce,î i.e., reverse its radial motion. In 1957 and in a paper we offer separately, Hermann Bondi demonstrated that gravitation waves indeed carry energy, and furthermore that in order to carry energy (and momentum), gravitational waves must be nonlinear. Gravitational waves, or ripples in the fabric of spacetime, were first predicted by Einsteinís 1916 general theory of relativity. In February 2016, the September 2015 detection of gravitational waves ñ waves first predicted by Einstein over a hundred years ago ñ was announced. CONDITION & DETAILS: First edition offprint. 4to. 10 X 6.75 inches; 250 x 169mm. Clean and bright. Very good condition in every way.

Gravitational waves, or ripples in the fabric of spacetime, were first predicted by Einsteinís 1916 general theory of relativity. In February 2016, the September 2015 detection of gravitational waves ñ waves first predicted by Einstein over a hundred years ago ñ was announced. Bondiís 1957 paper firmly established the physical reality of gravitational waves; his later work in the early 1960s ñ and this is one of those papers -- would put "their physical properties such as energy and momentum flux on a rigorous mathematical footingî (Denef, Science, Feb. 2016). I n this 1964 paper, the contemporary discovery of quasi-stellar objects and pulsating radio sources, for example, had re-sparked ìinterest in the application of general-relativity theory to the structure of massive or highly condensed stars. In some of the resulting models attempts have been made to include a radiation field in the calculationsî (Kaufmann, ìThe Exterior Solution, AJ 156, 257). Bondiís paper presents one such model. Of this 1964 paper, Bondi wrote: ìEarlier ideas associating an invariant integral of the energy invariant with the number of nucleons in a gravitating body are shown to be fallacious, and thus do not provide a means of following through the contraction of such a body. It is shown how the full field equations of general relativity give a feasible and rigorous method of examining contracting models. Schwarzschild-type co-ordinates are introduced and are used to examine the slow adiabatic contraction of a sphere of constant density. The particle paths are found and the pressure-density relation permitting such slow adiabatic contraction is examined. It is shown that the simple 4/3 power law of Newtonian theory has to be replaced by a steeper dependence of pressure on density for high gravitational potentials. Radiation co-ordinates are introduced to examine radiating contracting systems, and equations fully specifying such a system are obtained. A simple example is given in outline to illustrate the methodî (Bondi, PRS, 281, 1964, p. 39). CONDITION & DETAILS: First edition offprint. 4to. 10 X 6.75 inches; 250 x 169mm.

Contact seller5-star seller1st Edition. FIRST EDITION OFFPRINT of ìfamous paper in classic astrophysicsî (SAO/NASA Astrophysics Data System). This paper by the Anglo-Austrian physicist Hermann Bondi studies whether redshifts could be of gravitational origin and ìserved as a theoretical guidepost for planetary and super-planetary relative motion calculatio…nî (ibid). In it he proves that ìwhatever equation of state is chosen, provided it is physically realistic (i.e., with sound speed in the material not exceeding the speed of light), the gravitational surface redshift due to the presence of a massive object like a white dwarf or neutron star cannot exceed 0.62î (Kembhavi, Quasars and Active Galactic Nuclei, 6). For this paper, Bondi adopted the field equations of general relativity ìand physically plausible equations of stateÖ in order to calculate the maximum surface redshiftÖ Bondi [states] that his models give the largest values of surface redshifts among spherically symmetric massive objectsî (Yabushita, MNRAS, 174, 1976, p. 637; MNRAS, 177, 1976, p. 595). Spherical in nature, Bondiís ìmodels are such that a core is surrounded by a thin mass shell or an adiabatically stable envelope. The equation of state in the core is p = qp, where p and p are pressure and energy-density, respectively and q a constant (q = 1/3 or 1)î (ibid). I In 1957 and in a paper we also offer, ìPlane gravitational waves in general relativityî, Bondi had ìfirmly established the physical reality of gravitational wavesî (Denef, Science, Feb. 2016). This 1964 paper is one of a series of papers that Bondi and his collaborators wrote in the early 1960s as they further studied gravitational waves. Their work put ìthe physical properties [of gravitational waves] such as energy and momentum flux on a rigorous mathematical footingî (ibid). Gravitational waves, or ripples in the fabric of spacetime, were first predicted by Einsteinís 1916 general theory of relativity. In February 2016, the September 2015 detection of gravitational waves ñ waves first predicted by Einstein over a hundred years ago ñ was announced. CONDITION & DETAILS: Offprint, Proceedings of the Royal Society. London: Harrison and Sons. Quarto (10 x 7 inches; 250 x 175mm).

Contact seller5-star seller1st Edition. FIRST EDITION, RARE OFFPRINT OF AN IMPORTANT LECTURE DELIVERED BY BONDI AT OXFORD IN MAY OF 1962; this is the first printed version. The following represent just a few scientists whose work Bondi speaks of in his lecture: Michelson-Morley, Milne, Lorentz, Einstein, Maxwell, Wheeler, Feynman, Hogarth, Penrose, Gold,…Percival, CarathÈodory. In 1957 and in a paper we offer separately, Hermann Bondi demonstrated that gravitation waves indeed carry energy, and furthermore that in order to carry energy (and momentum), gravitational waves must be nonlinear. Gravitational waves, or ripples in the fabric of spacetime, were first predicted by Einsteinís 1916 general theory of relativity. In February 2016, the September 2015 detection of gravitational waves ñ waves first predicted by Einstein over a hundred years ago ñ was announced. Bondiís 1957 paper firmly established the physical reality of gravitational waves; his later work in the early 1960s ñ and this is one of those papers -- would put "their physical properties such as energy and momentum flux on a rigorous mathematical footingî (Denef, Science, Feb. 2016). In this 1962 lecture, Bondi states: ìIf we suppose that there are some models of the Universe in which the disequilibrium between past and future depends on the actual cross-section for absorption, then we are led to consider whether this is large enough in all cases, and naturally our minds turn to neutrinos. As you know, their interaction cross-section is very small. Could it be that with neutrinos the disequilibrium between past and future is not sufficient to produce a sense of time?î (Bondi, ìPhysics and Cosmology,î 1962). CONDITION & DETAILS: First edition offprint. 4to. 9 X 6 inches; 225 x 150mm. Very tiny fold at the right foot, not impacting any text; the same small fold on the final page is starting to break loose but is holding. Bright and clean. Very good condition.

Contact seller5-star sellerBOUND FIRST EDITION OF HERMANN BONDIíS SEMINAL 1957 THOUGHT EXPERIMENT DEMONSTRATING THAT GRAVITATIONAL WAVES INDEED CARRY ENERGY, and furthermore that in order to carry energy (and momentum), gravitational waves must be nonlinear. Gravitational waves, or ripples in the fabric of spacetime, were first predicted by Einsteinís 191…6 general theory of relativity. Bondiís paper firmly established the physical reality of gravitational waves; his later work in the early 1960s (and in papers we also offer) would put "their physical properties such as energy and momentum flux on a rigorous mathematical footingî (Denef, Science, Feb. 2016). In February 2016, the September 2015 detection of gravitational waves ñ waves first predicted by Einstein over a hundred years ago ñ was announced. Inspired by conversations with and a presentation by British theoretical physicist Felix A. E. Pirani early in the same year, Bondi began to study gravitational radiation, ìin particular the question of quantifying the energy and momentum carried off 'to infinity' by a radiating systemî (Wikipedia). At his Chapel Hill conference presentation, Pirani had described the ìmathematical properties of general relativity that led Feynman to propose a thought experiment called ëthe sticky bead argumentí for gravitational wavesî (History of Physics: The Wenner Collection). The sticky bead argument is a thought experiment presented at the same conference. It was designed by Feynman to illustrate that the gravitational radiation first predicted by Einsteinís theory of general relativity does in fact exist (see note below). The experiment envisions a gravitational wave causing beads on a stick to vibrate, resulting in frictional heating; Feynman believed that this evidence of physical effects demonstrated that a gravitational wave transports energy and is therefore measurable. Feynman ìfelt that any system which could be an absorber of waves could also be an emitter. For these reasons, he expected gravitational waves to existî (Foenner, The Expanding Worlds of General Relativity, 220). The work of Feynman and Pirani convinced Bondi that two papers of significance published in the late 1930s, papers by Nathan Rosen needed to be refuted and he did so in the form of a letter printed in Nature ñ the document offered here. Writing in both an American and a Soviet journal, Rosen had argued ìthat plane gravitational waves were an impossibility due to the ineradicability of singularities in the metricî (ibid). Bondiís letter, ìPlane gravitational waves in general relativity,î is his refutation of Rosenís work and is his argument ñ using what he learned from Feynman and Pirani -- in favor of the existence of Einsteinís gravitational waves. Over a hundred years later science would prove both Einstein and Rosen correct. Note: ìBondi supposedly learned of the sticky bead argument from Feynman at the Conference on the Role of Gravitation in Physics at the University of North Carolina, Chapel Hill, March 1957, but there are conflicting versions of this story. Daniel Kennefick, in Traveling at the Speed of Thought (2007) reports that Bondi came up with the sticky bead idea independently at the meeting and suggests that Weber and Wheeler may have also done soî (Wenner). ALSO INCLUDED: Harold C. Urey's "Origin of Tektites" (pp. 556-557). Here Urey suggests that tektites are a by-product of collision of a comet with the earth. CONDITION & DETAILS: Full bound volume.
