Zero Point Energy Does Not Imply Planck's Radiation Law, and Does Not Replace the Quantum Assumption Gauge Institute Journal Volume 15, No 3, August 2019 H. Vic Dannon Zero Point Energy Does Not Imply Planck's Radiation Law, And Does Not Replace the Quantum Assumption H. Vic Dannon [email protected] March 1999 Revised July 2019 Abstract Zero point energy was introduced by Planck in 1912 in his second radiation law. In the derivation of his Radiation Law, Planck assumed that the radiation energy of his oscillator includes Zero Point Energy 1 w , 2 even at absolute temperature zero. Planck was unaware of his assumption. He believed that quantized energy implied the Zero Point Energy. Actually, Planck's Zero Point Energy is an assumption independent of the well-established fact that energy is quantized. In 1913, Einstein-Stern proposed that Zero Point Energy implies Planck's radiation law with no need for assuming quantized energy. 1 Gauge Institute Journal Volume 15, No 3, August 2019 H. Vic Dannon We show here that Einstein-Stern Dipole Model that assumes Zero Point Energy fails to produce Planck's Radiation Law, and is inconsistent with it. In 1916, Einstein gave up quietly on that claim. His final treatment of Radiation does not mention Zero Point Energy. But in 1969 that claim was revived in a paper by Boyer. Boyer never supplied any derivation of the radiation law, with or without quantum assumptions. We show here that his proposed equation leads to a Ricatti type differential equation, with infinitely many solutions, that are inconsistent with the radiation law.

Planck’s Zero Point Energy In 1912, Planck derived his second radiation law that includes Zero Point Energy by assuming that Zero Point Energy. Unaware of his assumption, he believed that his quantum hypothesis implied the zero point energy. Had he utilized his 1901 derivation to obtain his second radiation law, as we do here, he might have noticed that assumption. His 1912 derivation masked the assumption of his Zero Pint Energy. Thus, he was unable to refute Einstein’s claim that zero point energy alone without quantum hypothesis can imply the first radiation law. Planck was not aware of the necessity of both the ZPE and the quantum hypothesis in his models for the derivation of his second radiation law that includes Zero Point Energy. 1.1 Planck's Assumption of Zero Point Energy Planck’s assumptions in his 1912 paper define a harmonic oscillator with evenly spaced energy levels differing by w .

Vic Dannon This derivation’s assumptions are equivalent to the harmonic oscillator given by the Schrödinger equation. The assumptions that guarantee the radiation law with ZPE for the harmonic oscillator model include the evenly spaced energy levels, the ZPE, and the quantum hypothesis. We see that the quantum hypothesis in Planck’s derivation of his radiation law, does not imply the zero point energy. It is the hidden assumption of ZPE in the oscillator’s average energy that leads to ZPE in the radiation law. Thus, Planck’s derivation does not establish the existence of ZPE. It only recovers what was assumed at the start. 1.2 The Likelihood of Zero Point Energy From 1= u + 1 p w 2 = 1+ 1+ 1 2w 2 ekT - 1 w kT = e , w ekT - 1 we have w ekT - 1 p = w ekT 9 Gauge Institute Journal Volume 15, No 3, August 2019 H.

That is, Planck assumed Zero Point Energy in his derivation with almost 100% certainty. Planck’s “discovery” of zero point energy was instrumental in prompting Einstein-Stern to look for an experimental confirmation in Eucken’s specific heat data. Their analysis precedes Mulliken’s observation of zero point energy in vibrations of isotopes. [Mulliken]. 10 Gauge Institute Journal Volume 15, No 3, August 2019 H. Vic Dannon 2.

    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Catalogo dei prodotti della ricerca Chapter 3 Putting the Quantum to Work: Otto Sackur’s Pioneering Exploits in the Quantum Theory of Gases Massimiliano Badino and Bretislav Friedrich After its appearance in the context of radiation theory, the quantum hypothesis rapidly diffused into other fields. By 1910, the crisis of classical traditions of physics and chemistry—while taking the quantum into account—became increas- ingly evident. The First Solvay Conference in 1911 pushed quantum theory to the fore, and many leading physicists responded by embracing the quantum hypoth- esis as a way to solve outstanding problems in the theory of matter. Until about 1910, quantum physics had drawn much of its inspiration from two sources. The first was the complex formal machinery connected with Max Planck’s theory of radiation and, above all, its close relationship with probabilis- tic arguments and statistical mechanics. The fledgling 1900–1901 version of this theory hinged on the application of Ludwig Boltzmann’s 1877 combinatorial pro- cedure to determine the state of maximum probability for a set of oscillators. In his 1906 book on heat radiation, Planck made the connection with gas theory even tighter. To illustrate the use of the procedure Boltzmann originally developed for an ideal gas, Planck showed how to extend the analysis of the phase space, com- monplace among practitioners of statistical mechanics, to electromagnetic oscil- lators (Planck 1906, 140–148). In doing so, Planck identified a crucial difference between the phase space of the gas molecules and that of oscillators used in quan- tum theory.

  • Design of Experiments for Light Speed Invariance to Moving Observers
    Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 24 February 2021 doi:10.20944/preprints202102.0547.v1 DESIGN OF EXPERIMENTS FOR LIGHT SPEED INVARIANCE TO MOVING OBSERVERS Design of experiments for light speed invariance to moving observers Revised 2/22/2021 08:08:00 Qian Chen International Education Foundation 4667 Highland Ct, Grandville, MI, USA 49418 e-mail: [email protected] The principle of the constancy of the velocity of light, which stated that the light velocity is invariant to the motion of the emitter, was well established and directly proven by experiments. Interestingly, the further assumption that the light velocity is independent of the motion of the observer was, arguably, never directly proven by any experiment for a century. This paper proposed the design of two experiments to directly test this assumption, which tried to address some perceived technical difficulty in such experiments. One is to directly measure the light speed as to moving sensors. The experiment setup is designed in such a way that the concerns of time synchronization and dilation can be avoided. Another experiment is to test the isotropy of the light speed to a moving particle in the electromagnetic accelerator by measuring the momentum to acceleration ratio. The experiment result, if positive, will provide direct and solid proof of the assumption. Otherwise, it may imply a need for further investigation. Since the light speed invariance to moving observers is a key assumption of some fundamental physical theory, either way, the experiments will have significant meanings. Keywords: Light velocity, Special Relativity, Time dilation, Time synchronization, Sagnac effect, Mass- Energy relationship, Particle acceleration, Michelson-Morley experiment, Asymmetry Theory search for direct experimental proof is of significant I.

  • The Collaboration of Mileva Marić and Albert Einstein
    Asian Journal of Physics Vol 24, No 4 (2015) March The collaboration of Mileva Marić and Albert Einstein Estelle Asmodelle University of Central Lancashire School of Computing, Engineering and Physical Sciences, Preston, Lancashire, UK PR1 2HE. e-mail: [email protected]; Phone: +61 418 676 586. _____________________________________________________________________________________ This is a contemporary review of the involvement of Mileva Marić, Albert Einstein’s first wife, in his theoretical work between the period of 1900 to 1905. Separate biographies are outlined for both Mileva and Einstein, prior to their attendance at the Swiss Federal Polytechnic in Zürich in 1896. Then, a combined journal is described, detailing significant events. In additional to a biographical sketch, comments by various authors are compared and contrasted concerning two narratives: firstly, the sequence of events that happened and the couple’s relationship at particular times. Secondly, the contents of letters from both Einstein and Mileva. Some interpretations of the usage of pronouns in those letters during 1899 and 1905 are re-examined, and a different hypothesis regarding the usage of those pronouns is introduced. Various papers are examined and the content of each subsequent paper is compared to the work that Mileva was performing. With a different take, this treatment further suggests that the couple continued to work together much longer than other authors have indicated. We also evaluate critics and supporters of the hypothesis that Mileva was involved in Einstein’s work, and refocus this within a historical context, in terms of women in science in the late 19th century. Finally, the definition of, collaboration (co-authorship, specifically) is outlined.

  • Quantum Mechanics As a Theory of Relativistic Brownian Motion 3
    ANNALEN DER PHYSIK 7. FOLGE * BAND 27, HEFT 1 * 1971 Quantum Mechanics as a Theory of Relativistic 6RowNian Motion By Yu.A.RYLOV Abstract It is shown that non-relativistic quantum mechanics can be treated as a kind of relati- vistic statistical theory which describes a random motion of a classical particle. The theory is relativistic in the sense that for the description of the particle behaviour the relativistic notion of the state is used. This is very important because a statistics is a state calculus and the result depends on the definition of the notion of state. Attempts by different authors [1-1411) to treat quantum mechanics from the position of classical theory did not lead to full success2). Though it may seem paradoxical, the reason there of, in our opinion, lies in the fact that the attempts to understand non-relativistic quantum mechanics were based on non-relati- vistic classical mechanics. In this paper we shall show that quantum mechanics is a variety of the re- lativistic theory of BRowNian motion3). The difference of our approach from approaches of others lies in the fact that we treat non-relativistic quantum mechanics from the point of view of relativistic classical mechanics. New principles are not needed for understanding the quantum mechanics of a single particle in this approach. In particular, such specific quantum mechanical principles as the uncertainty and the correspondence principle may be under- stood from the classical position. The clue to such an approach is the relativistic notion of system state. 1. The notion of state In non-relativistic physics the state of a physical system is defined4) as a set of quantities which are given at a certain moment of time and determine these quantities at any subsequent moment of time.

Einstein introduced the concept of “light quanta”, an indivisible packet, although it was not until 1926 when the term “photon” (coined by Gilbert Lewis (https://en.wikipedia.org/wiki/Gilbert_N._Lewis) (1875-1946) in an article published in Nature) substituted Einstein’s “light quanta” forever. Of course, this year 2015 marks the centenary of the publication of Einstein’s papers on general relativity and –as the IYL 2015 Resolution points out – “the embedding of light in cosmology thorough general relativity”. However, perhaps it is not so well known that Einstein also made several seminal contributions to the science of light.

Sommerfeld’s extension of Bohr’s atomic model was moti- vated by the quest for a theory of the Zeeman and Stark effects. The crucial idea was that a spectral line is made up of coinciding frequencies which are decomposed in an applied field. In October 1914 Johannes Stark had published the results of his experimental investigation on the splitting of spectral lines in hydrogen (Balmer lines) in electric fields, which showed that the frequency of each Balmer line becomes decom- posed into a multiplet of frequencies. The number of lines in such a decomposition grows with the index of the line in the Balmer series.

  • Normal Typicality and Von Neumann's Quantum Ergodic Theorem
    Normal Typicality and von Neumann’s Quantum Ergodic Theorem Sheldon Goldstein,∗† Joel L. Lebowitz,∗‡ Christian Mastrodonato,§¶ Roderich Tumulka,∗k and Nino Zangh`ı§∗∗ April 15, 2010 Abstract We discuss the content and significance of John von Neumann’s quantum er- godic theorem (QET) of 1929, a strong result arising from the mere mathematical structure of quantum mechanics. The QET is a precise formulation of what we call normal typicality, i.e., the statement that, for typical large systems, every initial wave function ψ0 from an energy shell is “normal”: it evolves in such a way that ψt ψt is, for most t, macroscopically equivalent to the micro-canonical | ih | density matrix. The QET has been mostly forgotten after it was criticized as a dynamically vacuous statement in several papers in the 1950s. However, we point out that this criticism does not apply to the actual QET, a correct statement of which does not appear in these papers, but to a different (indeed weaker) state- ment. Furthermore, we formulate a stronger statement of normal typicality, based on the observation that the bound on the deviations from the average specified by von Neumann is unnecessarily coarse and a much tighter (and more relevant) bound actually follows from his proof.

Cetto Instituto de F´ısica, Universidad Nacional Autonoma´ de Mexico´ Apdo. Post. 20-364, 01000 Mexico,´ D.F., Mexico Recibido el 19 de marzo de 2001; aceptado el 3 de julio de 2001 In this paper we show that a strong link exists between Planck’s blackbody radiation formula and the zeropoint field. Specifically, the hypothesis that the equilibrium field (including the zeropoint term) follows a canonical distribution, in combination with the requirements that its specific heat remain finite as the temperature T ! 0 and that it behave classically as T ! 1, implies that the energy of the zeropoint field has a fixed value and leads to Planck’s law for the equilibrium distribution at arbitrary T ; this in turn implies quantization of the energy of the field oscillators. There is no need to introduce any quantum property or ad hoc assumption for the purpose of the present derivation. Keywords: Zeropoint field; Planck’s law; blackbody radiation; energy quantization. En este trabajo se exhibe la existencia de una estrecha relacion´ entre la formula´ de Planck para la radiacion´ de cuerpo negro y el campo de punto cero. Espec´ıficamente, la hipotesis´ de que el campo de equilibrio (incluido el termino´ de punto cero) sigue una distribucion´ canonica,´ junto con las demandas de que su calor espec´ıfico se mantenga finito conforme T ! 0 y de que se comporte clsicamente para T ! 1, implica que la energ´ıa del campo de punto cero tiene un valor fijo y conduce a la ley de Planck para la distribucion´ de equilibrio a temperatura arbitraria; esto a su vez implica la cuantizacion´ de la energ´ıa de los osciladores del campo.

  • On the Electrodynamics of Moving Bodies
    ON THE ELECTRODYNAMICS OF MOVING BODIES By A. EINSTEIN June 30, 1905 It is known that Maxwell’s electrodynamics—as usually understood at the present time—when applied to moving bodies, leads to asymmetries which do not appear to be inherent in the phenomena. Take, for example, the recipro- cal electrodynamic action of a magnet and a conductor. The observable phe- nomenon here depends only on the relative motion of the conductor and the magnet, whereas the customary view draws a sharp distinction between the two cases in which either the one or the other of these bodies is in motion. For if the magnet is in motion and the conductor at rest, there arises in the neighbour- hood of the magnet an electric field with a certain definite energy, producing a current at the places where parts of the conductor are situated. But if the magnet is stationary and the conductor in motion, no electric field arises in the neighbourhood of the magnet. In the conductor, however, we find an electro- motive force, to which in itself there is no corresponding energy, but which gives rise—assuming equality of relative motion in the two cases discussed—to elec- tric currents of the same path and intensity as those produced by the electric forces in the former case. Examples of this sort, together with the unsuccessful attempts to discover any motion of the earth relatively to the “light medium,” suggest that the phenomena of electrodynamics as well as of mechanics possess no properties corresponding to the idea of absolute rest.
