Ideas in the History of Nano/Miniaturization and (Quantum) Simulators: Feynman, Education and Research Reorientation in Translational Science
2015
Cultural history of nanominiaturization, computing, quantum computing and simulating is necessary to comprehend human character and place it in the whole of living beings. Ideas in the history of physics by Feynman, etc. are valued by the questions that generate. A series of questions, answers and hypothesis introduces the nature of the history of nanominiaturization, providing facts. Nanotechnology adds a third dimension to the periodic table of the elements. Thinking about computers was useful. It must do with learning computers possibilities and physics potential. Provisional conclusions follow. (1) Nature (space–time) is not classical but discrete; quantization is a different kind of ma…

L'epistolario ritrovato. Le lettere “napoletane” di Baldassarre Boncompagni a Gilberto Govi.
2016
In questa nota forniamo il testo di numerose lettere inviate dallo storico della matematica Baldassarre Boncompagni al fisico e storico della fisica Gilberto Govi. Queste lettere erano conservate presso il Dipartimento di Matematica ed Applicazioni “Renato Caccioppoli” dell’Università di Napoli Federico II. Esse attualmente devono essere considerate disperse. Il testo allora è tratto da alcune fotografie ritrovate tra le carte dello storico della matematica Franco Palladino recentemente scomparso
On the history of the PMNS Matrix... with today's perspective
2013
The conceptual basis for understanding the interplay of neutrino mass and mixing for neutrino oscillations were paradoxically discussed in a period when the prevailing view was that of massless neutrinos. The name of Bruno Pontecorvo is associated to most of the components for this beautiful quantum phenomenon: muon-electron universality, different neutrino flavours, mismatch between weak interaction and mass eigenstates, neutrino oscillation phenomenology, including flavour and Majorana transitions.
Einstein's Washington Manuscript on Unified Field Theory
2020
In this note, we point attention to and briefly discuss a curious manuscript of Einstein, composed in 1938 and entitled "Unified Field Theory," the only such writing, published or unpublished, carrying this title without any further specification. Apparently never intended for publication, the manuscript sheds light both on Einstein's modus operandi as well as on the public role of Einstein's later work on a unified field theory of gravitation and electromagnetism.
Astrophysik contra Astronomie
1981
[Astrophysics contra astronomy] means the displacement of astrometry and stellar astronomy as the main and solely conceded branches of astronomy by the new astrophysics. This displacement started with the introduction of spectroscopic and photometric methods of observation in astronomy founded by J. C. F. Zoellner and W. Huggins in the late 1850s. It was Zoellner, too, who gave the methodical and intrumental foundations of the new branch called consciously [Astrophysik] by him, because it gives insight into the [physical constitution] of the celestial bodies - whereas the traditional astronomy (or: astrophysics according to the older meaning) had been studying only the motions of the stars …
Das Werden des Kosmos Von der Erfahrung der zeitlichen Dimension astronomischer Objekte im 18. Jahrhundert
1985
The Permanent ‘Becoming’ of the Cosmos: On Experiencing the Time Dimension of Astronomical Entities in the 18th Century. - This paper deals with two of the initial stages through which the dimension of time, in the sense of an irreversible development, found its way into astronomical-cosmological thinking. The one resulted from the first consequental application of Newtonian principles and laws to cosmic entities outside of our solar system found in the General Natural History or Theory of the Heavens of Immanuel Kant (1755): Endeavoring to explain through natural causes first the peculiarities of the solar system, no longer naturally explainable through the celestial mechanics of Isaac New…

Towards a model of Quintessential Inflation
2000
A model of quintessential inflation is presented, which manages to achieve the requirements of both inflation and quintessence with natural values of the mass-scales and parameters.
Fifty Years of Mössbauer Spectroscopy in Solid State Research - Remarkable Achievements, Future Perspectives
2011
Mossbauer spectroscopy was founded more than fifty years ago based on an outstanding discovery by the young German physicist Rudolf Ludwig Mossbauer while working on his Ph.D. thesis. He discovered the recoilless nuclear resonance fluorescence of gamma radiation and was awarded the Nobel Prize in Physics in 1961 as one of the youngest recipients of this most prestigious award. His discovery led to the development of a new technique for measurements of hyperfine interactions between nuclear moments and electromagnetic fields. This method, with highest sharpness of tuning of 10–13, yields information on valence state, symmetry, magnetic behavior, phase transition, lattice dynamics and other s…
