Biography

Umberto Bartocci was born in Rome, in 1944. In 1967 he graduated in Pure Mathematics with Prof. Beniamino Segre, and then he became his Assistant. After two years of specialization in Cambridge (UK), in 1976 he was appointed Full Professor of Geometry at the University of Perugia. Since then, in Perugia he taught many mathematical courses, mostly concerning Algebra and Geometry, and since 1980 even History of Mathematics.

He slowly realized that there was a strong ideological connection between Darwinism, the formalistic foundation of Mathematics which lead to a Mathematics without Intuition, and the "irrationalistic" development of 20th Century Physics, which started with Relativity and arrived to the widespread interpretation of Quantum Mechanics. The empirical success of Physics reinforced which in his opinion was a bad Philosophy of Mathematics, and he understood that any critical approach to the foundations of his own discipline was impossible, unless it did involve foundations of Physics too.

Thus he started studying the logical and empirical foundations of Relativity, in a long intellectual travel which led to the organization of international meetings, publishing papers, and more recently even the edition of the journal Episteme. Rather deluded for the negligible results attained in front of a great effort, he did retire from teaching and research in 2006.

Description

This book presents 26 papers concerning important fundamental questions in mathematics and physics. Is a line a continuum or a dense set of points? Is space empty or does it contain an ether? Is the ether a sea of virtual particles or a gravitational field? Does quantum theory say nature is actually unpredictable? Can alternative logics resolve paradoxes in physics? Are the space-time ideas of relativity tenable? Can absolute velocities be measured? Can conservation of energy be violated? Why are gravitational and inertial masses equal? Does mass really change with velocity? The authors do not agree with each other. Some accept relativity, while others say it is wrong. The observed force between suspended antennas and the results of many other experiments contradict Maxwell theory and special relativity and are predicted by classical Weber electrodynamics. Some claim quantum behavior is intrinsically unpredictable; while others claim microphysical reality and suggest crucial experiments to prove their point. There is a claim to having observed cold nuclear fusion in a spark discharge. There is a claim to having violated the conservation of momentum and energy experimentally. The Weber potential (so successful in electrodynamics) when applied to gravitation predicts the mass-times-acceleration force as an induction force due to the far mass in the universe, verifying Mach?s principle and proving the identity of gravitational and inertial mass. A unipolar device is described that is supposed to extract energy from space. The Weber potential also predicts the result of the Kaufmann-Bucherer experiments; so mass may not, in fact, vary with velocity. This book presents some new important concrete results. It may not provide the reader with the particular answers he seeks; but many of the important fundamental questions are presented; and it provides a gold mine of references to facilitate the search for further answers.

Description

The book by Umberto Bartocci, Albert Einstein and Olinto De Pretto: The True Story of the Most Famous Formula in the World (Bologna, Andromeda, 1999) is likely to become even more rare than De Pretto if the publisher does not hasten to reprint. The book is part of the series History impossible, is a book just in time, that is printed just in time, in time to be saved.  It is 'the fate of those books that publishers do not consider suitable for publication and that without such a formula would not be able to ever see the light. The manuscripts would fall into oblivion, with the passage of time should be lost in a move or because of some relative distracted.  Are the chills to think about how many novels, essays or those who scientific work has been denied even the simple come to light. Certainly the story was written by unknown hands, which sometimes was not the slightest trace. And it is very exciting to follow these mysterious footsteps. In the near future - and can play almost as a joke - the book Bartocci may be disputed by bibliophiles in search of original texts and prophetic, that do not have marked an era when their silent exit, but they did afterwards, as anticipatory of truth have become such only in the future, sometimes a distance of many years. It is a simple paperback publishing in the eighth, with the black cover on all sides. The face of Einstein and the atomic mushroom that campeggio sul front are two very clear symbols of the concept expressed by the most famous formula in the world. Before that book Bartocci had tried - in vain - to accept for publishing a four-hands, with Marco Mamone Capria on the same topic. The scientific journal to which he had directed the rejected manuscript, in a courteous but final.  All these difficulties stem from the responsibility that is behind the name of Albert Einstein. Still too great and splendid is its star to be able to blur without exposing brutally critical of the 'scientific orthodoxy. Einstein can not be questioned, not yet, at least. Perhaps one day new conceptions of the world of physics toned down his theories, but at the moment remains an immovable pillar, slightly less than untouchable. For this reason that no magazine wants to be a voice worthy of note in academic would dare hold a decidedly "against the tide" that is not supported by evidence and irrefutable around a doubt - albeit qualified - on the paternity of the most famous formula world. It is logical that the problem at the moment can not be presented to a level of conjecture. It is not yet certified, if it ever will be, that Albert Einstein read the work of Olinto De Pretto and, above all, it drew inspiration. Perhaps the only feasible way is to focus attention on the figure of Michele Besso, who was a friend Einstein and connected to De Pretto. Einstein knew Italian, also held conferences in our language.  The science seems not to want to make that De Pretto, this obscure agronomist Vicenza, perhaps inspired the great scientist. Maybe they are formal, not decisive, since the concept of ether does not seem to be applied to the theory of relativity, but certainly the phrase that appears in the work of De Pretto 1904 (a year before Einstein published in Annalen der Physik his two famous works) is explanatory in this regard: "The matter of whatever a body contains in itself a sum of energy represented the entire mass of the body, which moved all united and collectively in space, with the same velocity of individual particles. [...] the mv formula gives us the strength and the living formula mv2 gives us, expressed in calories, such energy.  Since m = lev equal to 300 million meters, which would be the speed of light, also admitted to the ether, everyone will see that you get a lot of calories represented by 10,794 followed by 9 zeroes that is, more than ten million million."

A Simple Classical Interpretation of Fizeau's Experiment

Abstract:

It is well known that Stokes's aether dragged theory is one of the best classical aether theories, since it is in agreement with almost all experimental results (see for instance R. Resnick's popular textbook: Introduction to Special Relativity). This theory is usually dismissed on the grounds of two natural phenomena, which are said to be "unexplainable" in Stokes's conceptual context: Bradley's astronomical annual aberration, and the speed of light in moving water (Fizeau's experiment). In this paper, a simple "time-delay" model for the behaviour of light in a transparent medium is given, which at least gets rid of the second of the two previous objections.

Symmetries and Asymmetries in Classical and Relativistic Electrodynamics

Abstract:

By a comparison between maxwell's electrodynamics classically interpreted (MT) and relativistic electrodynamics (RED), this paper discusses whether the "asymmetries" in MT mentioned by A. Einstein in his 1905 relativity paper are only of a conceptual nature of rather involve specific empirical claims. It is shown that in fact MT predicts strongly asymmetric behaviour for very simple interactions, and an analysis is made of the extent of the ?symmetry? achieved by means of relativistic postulates. A "low" velocity experiment is suggested which could provide another test of the accuracy of RED with respect to MT.

Abstract:

In connection with a note by Rindler on relativity and electromagnetism, it is shown that classically interpreted electromagnetism and special relativity already diverge in their predictions on the behavior of a very simple electrodynamical system, even for 'low' velocities.
