Have you read Baruch? La Fontaine used to cry, enthusiastically. To-day he would have troubled his friends with the question Have you read Einstein?But, whereas one needs only a little Latin to gain access to Spinoza, frightful monsters keep guard before Einstein, and their horrible grimaces seem to forbid us to approach him. They stand behind strange moving bars, sometimes rectangular and sometimes curvilinear, which are known as co-ordinates. They bear names as frightful as themselvescontravariant and covariant vectors, tensors, scalars, determinants, orthogonal vectors, generalised symbols of three signs, and so on.These strange beings, brought from the wildest depths of the mathematical jungle, join together or part from each other with a remarkable promiscuity, by means of some astonishing surgery which is called integration and differentiation.In a word, Einstein may be a treasure, but there is a fearsome troop of mathematical reptiles keeping inquisitive folk away from it; though there can be no doubt that they have, like our Gothic gargoyles, a hidden beauty of their own. Let us, however, drive them off with the whip of simple terminology, and approach the splendour of Einsteins theory.

In questo suo breve saggio, Daniele Biancardi riassume sinteticamente le cause del celebre libro di Charles Darwin Lorigine della specie (1859), nel quale il famoso biologo spiega la sua teoria dellevoluzione, riportando le osservazioni che egli stesso aveva compiuto durante una spedizione, secondo cui gruppi di organismi di una stessa specie si evolvono gradualmente nel tempo, attraverso il processo di selezione naturale.

A dialogue between science and spirituality is a necessity in our times where both, differences and mutual enrichment of the two great fields of human approach to reality, are taking place. This volume addresses this need from the perspective of different areas of science and spiritual traditions. The starting point is the intention of the founder of the IIAS, Dr S. Radhakrishnan, who saw that both the practice of science and experience of spirituality are intimately related to being human. Although much thought has gone into their relationship, the present volume intends to broaden and deepen the possibility of a harmonious integration, necessary to overcome the present-day crisis of humanity.From the side of science, the contributors come from the fields of physics, plant biology, neuroscience, psychology, ecology and philosophy of science; and from the side of spirituality, following traditions and spiritual masters are represented: PAtajala Yoga, Trika aivism of Kashmir, VedAnta, Buddhism, Christianity, Theosophy, and Rabindranath Tagore, Swami Vivekananda and J. Krishnamurti. The deliberations included topics such as Awareness in plants, Neuroplasticity and Habit, appropriate use of terms such as Consciousness and Energy in different contexts, clarifying several issues concerning the on-going dialogue. The contributing scholars have built bridges of understanding, thus encouraging the reader to proceed further in this quest.

George Frederick Barker (1835-1910) was an American physician and scientist. Born in Charlestown, Massachusetts, he graduated from the Yale Scientific School in 1858. He was successively chemical assistant in Harvard Medical School, professor of Chemistry and Geology in Wheaton College and professor of Natural Science at the Western University of Pennsylvania. He subsequently went to Yale as a professor of Physiological Chemistry and Toxicology, and later was a professor of Physics at the University of Pennsylvania. He served as President of the American Association for the Advancement of Science in 1879, President of the American Chemical Society, Vice-President of the American Philosophical Society, and for several years an associate editor of the American Journal of Science.Modern Aspects of the Life-Question, the essay by George Frederick Barker that we offer today to the attention of modern readers, was the text of the speech delivered by him as outgoing president of the American Association for the Advancement of Science, at the meeting in Boston, August 25, 1880. In it the great American scientist explores the origins of life on Earth and the great mystery of existence.

Kein Zweig der menschlichen Kenntnisse bietet anziehendere Ergebnisse dar und erlaubt wichtigere Anwendungen auf das thatige Leben, als die Astronomie; aber keine wir mussen es mit Beschamung gestehn wenigstens bei uns Deutschen, ist weniger verbreitet als sie. Es ist wahrhaft emporend, wenn man, trotz der groen Anzahl von Lehrbuchern, in jedem Jahre Manner, die sich zu den Gebildeten, ja Gelehrten, zahlen, auftreten sieht, um in Druckschriften die grobste Unwissenheit zur Schau zu legen. Fast scheint es, da die allgemein gefurchtete Mathematik auch die Astronomie in ihren Bann mit fortgerissen habe. Auch lat sich nicht leugnen, da es fur einen der mathematischen Sprache unkundigen Leser ein sehr unangenehmes Geschaft ist, die Schlusse muhsam aus den ihm unverstandlichen Beweisen herauszusuchen, und die Mathematik selbst verlangt in der That ein viel zu ernstes Studium, und erscheint dem Anfanger zu schwer und zu trocken, als da man sie in den schon so weiten Studienkreis der Gebildeten ziehen konnte, und die ersten Anfangsgrunde reichen zum Verstehn der Astronomie bei weitem nicht aus. Zwar kundigen sich mehrere astronomische Lehrbucher als popular an, allein wenn die Leser, durch den Titel getauscht, eine durchgangig verstandliche Darstellung der Astronomie erwarten, so finden sie entweder die Mathematik in andrer Gestalt, wie bei Schuberts popularer Astronomie und La Places Exposition du systeme du monde, oder einen solchen Mangel an Grundlichkeit und Vollstandigkeit, da sie ihren Zweck nicht erreichen.

Many physicists have pointed out that the formulation of Quantum Mechanics is missing an important piece. Its theoretical incompleteness has been evoked, there has been talk of hidden variables, non-locality of the theory, provoking long debates which have left things at a standstill. There is even Einsteins famous phrase in which he says that "God does not play dice". A big mistake! If God did not play dice, as Darwin taught us, there would be neither evolution nor the immense variety of our world which would be limited to a single atom. Perhaps more simply the theory lacks an unprecedented operation of analysis and synthesis capable of providing the "missing part" or a new logical paradigm capable of making Quantum Mechanics understandable to human beings.The book starts from the basics with the analysis of the concept of Plancks constant h in terms of Minimum Action, i.e.: a flow of a quantum of energy in the unit of time. The next step is to formalize the motion as a phenomenon on the fabric of a space that is also quantized, recently back in fashion in Quantum Gravity.Attention! In this case a mysterious question arises: how can one conceive the movement of a particle between discrete areoles of space with solution of continuity? A promising idea may be that of resorting to the strange dual nature of wave-matter discovered by de Broglie by means of which the particle would not move but probably only its information is translated in wave form between spatial quanta. However, this idea requires a subquantum mechanism where the quantum vacuum becomes a key participatory element, or rather a fundamental intermediary already glimpsed in Alain Aspects experiments on entanglement. The development of a paradigm of the subquantum mechanism would show among other things that the main concepts of special and general relativity can be derived from Quantum Mechanics. This approach helps to clarify within an intelligible logical structure several obscure aspects of modern physics including Quantum Gravity itself and also the root cause for which space is curved by the presence of mass. In fact, according to advanced physics, space is anything but inconsistent, as supposed at the time by the Michelson-Morley test.Einsteins well-known reasoning -gedanken experiment- of the elevator represented an ingenious analogy on gravity capable of providing a final effect that can be calculated with extreme precision, alas overlooking the profound cause of the phenomenon. In fact, General Relativity does not predict that gravity implies invisible attractive forces between masses but only a deformable geometry that pilots the trajectories of the planets along the edge of a sort of funnel. Nevertheless, we have a problem namely that to bend a spatial fabric, by no means inconsistent, a force whose origin is obscure is needed. On this specific point no one has been able to provide an exhaustive logical framework. Instead, it seems that the existence of Matter in space requires quantized actions of energy without which the objects of the world would disappear instantaneously. Such an effect would delight the great physicist Ernst Mach who hypothesized mass as a condensation of accelerations that were exchanged between them in terms of gravitational attraction.(With a more philosophical approach see by the same author: "The hidden paradigm of Quantum Mechanics"- Streetlib).

Eccellenze, Signore, Signori,Leterno dibattito sullimportanza da attribuirsi agli studi scientifici in confronto agli studi classici ebbe un giorno a campioni, in Francia, attorno al 1840, un insigne astronomo e fisico, Francesco Arago, e lillustre autore delle Meditations poetiques, Alfonso Lamartine. Credeva Arago di aver inchiodato al muro lavversario, gridandogli: Non e colle vostre belle parole, che si fabbrica lo zucchero di barbabietola; ne con versi alessandrini che voi estrarrete la soda dal sal marino!. E soggiungeva: È la scienza che ha fatto cadere per sempre i pregiudizi!. Lamartine non negava che la scienza fosse utile; ma: Se il genere umano diceva fosse condannato a perdere interamente uno di questi due ordini di verita, o tutte le verita matematiche, o tutte le verita morali, esso non dovrebbe esitare a sacrificare le verita matematiche; perche, se si perdessero tutte le verita matematiche, lindustria, il mondo materiale, ne avrebbero indubbiamente un danno immenso; ma se luomo perdesse anche una sola delle verita morali acquisite cogli studi letterari, questo segnerebbe la morte sua e dellumanita intera. E concludeva inneggiando alle lingue che voi chiamate morte, e io chiamo immortali.Vedute matematiche su fenomeni e leggi naturali, Gino Fano.Gino Fano (Mantova, 5 gennaio 1871 Verona, 8 novembre 1952) e stato un matematico italiano.

This edition includes the following editors introduction:The importance of Charles Forts "The Book of the Damned" as a precursor of pseudoscienceOriginally published in 1923, New Lands is the second nonfiction book of the American author Charles Fort.There are many books that tell of sightings of ghosts, aliens, and strange animals, but Charles Forts "New Lands" is perhaps the only book in which whole continents, geographies, and, indeed, planetary systems themselves are seen in the same uncertain twilight of perception. "New Lands" deals primarily with incredible astronomical anomalies.Fort expands in New Lands on his theory about the Super-Sargasso Sea a place where earthly things supposedly materialize in order to rain down on Earth as well as developing an idea that there are continents above the skies of Earth. As evidence, he cites a number of anomalous phenomena, including strange "mirages" of land masses, groups of people, and animals in the skies. He also continues his attacks on scientific dogma, citing a number of mysterious stars and planets that scientists failed to account for.

The discovery of new elementary gas in the atmosphere in 1894 aroused much interest, and public attention has again been directed to the air, which was, for many centuries, a fruitful field for speculation and conjecture. The account of this discovery, communicated to the Royal Society in January 1895, was, however, necessarily couched in scientific language; and many matters of interest to the chemist and physicist were written in an abbreviated style, in the knowledge that the passages describing them would be easily understood by the experts to whom the communication was primarily addressed. But persons without any special scientific training have frequently expressed to me the hope that an account of the discovery would be published, in which the conclusions drawn from the physical behaviour of argon should be accompanied by a full account of the reasoning on which they are based. An endeavour to fulfil this request is to be found in the following pages. And as the history of the discovery of the better known constituents of the atmosphere is of itself of great interest, and leads up to an acquaintance with the new stranger, who has so long been with us incognito, an effort has here been made to tell the tale of the air in popular language.
