Everyone knows that Einstein’s special relativity contains a theory of time measurements, which are no longer conceived as absolute, but are related to the state of motion of the clock and to the point of view of the observer, and the same happens to space measurements. Everyone also knows that the theory contains the deduction that a small material mass can be converted into a huge amount of energy according to a precise quantitative relationship.But many who have tried to study the theory have failed to understand it; yet, to fully understand the part of Einstein’s theory about time and space measurements, readers just need to know what speed and square root are, and to obtain a simplified but clear idea of the part regarding the concepts of mass and energy they need just to remember elementary high-school physics. Apparently something is missing in all the many books that describe relativity in a simple or higher level.This book is written in a different way from any other. A rigorous but clear exposition will show all readers, provided they know what speed and square root are, that they can understand fully and perfectly the space-time theory and can judge it with their own intelligence. In addition, readers will have a clear idea of the equivalence between mass and energy and its logical relationship with space-time theory.This book was written for beginners and for perplexed people who have unsuccessfully attempted to study special relativity: both will understand the exact meaning of the famous and difficult essay in which Einstein expounded the theory in 1905, which is examined word by word in this book. And all readers will have a clearer idea of the relevance of relativity for the twentieth (and twenty-first) century culture.

Science at the Crossroads was published by Herbert Dingle in 1972 at the end of a gruelling controversy with the English scientific world about the clock paradox in Einstein’s special relativity. It is still a seminal text, which allows us to understand and evaluate, with Cartesian clarity, the problem of that paradox for all those readers who find themselves in a widespread condition of having studied Einstein’s special relativity or received a teaching of it, and yet of not feeling comfortable it because the attempt to understand the logical connection of the parts with the whole did not succeed. Many have experienced this state of mind, and can admit it. In this way Science at the Crossroads is an important source of knowledge about Einstein’s special relativity and its historical background.Science at the Crossroads contains a great wealth of philosophical and epistemological ideas. The essay has a classic imprint, rich with sharp and clear distinctions, and very elegant in style. We meet countless research possibilities concerning the mathematical idealism of anti-classical physics after 1920 (assuming it is still correct to call it physics rather than metaphysics, as Dingle would suggest, as a partisan of modern science empirical method). Every page written by Dingle suggests research that could be carried out in depth, starting from what Dingle observes on the origins of mathematical idealism in Maxwell himself and his displacement current postulated to ensure the continuity of a given mathematical function, to end with the extreme tendencies of this kind of thought that were manifested towards the 1970s, as for example in the case of Professor Hoyle mentioned in the last chapter, who “has plainly stated his advocacy of the process of telling nature what to do instead of looking to see what she does”. Naturally, it is our task to continue Dingle’s research up to the present.The present electronic edition provides a Foreword from the editor, which informs about the basic knowledge readers are expected to have in order to fully understand Science at the Crossroads.

Pragmatism and French Voluntarism, published in January 1914, is the doctoral thesis of Susan Stebbing, who was the first woman to hold a philosophy chair in the United Kingdom. It is an account of the epistemological ideas that were widespread and widely discussed in the early twentieth century: it introduces us methodically into the world of American pragmatism and of the many French currents of thought that we usually group together in a generic way under the title of anti-intellectualism, and which culminated in Bergson’s philosophy. Why read it today? First of all because inside this book we find a clear and intelligent account of the philosophical currents it deals with. Despite its age, this book is still a useful guide to orient oneself in the contexts of pragmatism and anti-intellectualism of the early twentieth century. Moreover, although it is a work written by the author in her young age and encyclopedic in nature, the personality of the author strongly acts in this book. Stebbing was throughout her life an intransigent critic, who never accepted compromise, of each kind of fall into irrational thinking of twentieth century culture. So this book is permeated with awareness of the deeply irrational and inconsistent statements which can be found in the epistemological currents in vogue at the time, and this awareness corresponds to a moral discomfort, clearly and strongly expressed, although still rudimentary and not articulated, because the times were not ripe to study the prevailing irrationalism in the culture of that era. Nor are they ripe still today: so the works of Stebbing are destined to be instruments for the historiography of the times to come, in precisely determining the falls in irrationality and the genesis of specific mythologies that we can recognize in the most unexpected places of twentieth century culture, and particularly in the science of nature.

Satan the Waster: A Philosophic War Trilogy with Notes & Introduction

LEE, VERNON

This book is aimed at people who simply know the basics of computer programming. It does not require any notion of physics and allows its readers to understand with total accuracy and in the simplest way the use that could be made of a quantum computer, by explaining step by step how to write a software to emulate its operation. The usual expression that a qubit “is an object that can be simultaneously in both binary states 0 and 1” will lose all the aura of mystery that surrounds it, and readers will understand exactly its meaning and implications for computing without the need for any knowledge of physics. The book describes quantum computing by considering it strictly from a computer science point of view, simply as a machine that is capable of transforming a given input into a given output using any suitable physical principle to work, and thus allows to become completely familiar with quantum gates and with the most famous quantum algorithms. The only condition is that the readers are familiar with some programming language and with the basic concepts of classical computer science: those who have this knowledge will easily follow the description of quantum algorithms and understand the software emulation that is implemented in the book, and will also have fun running and testing it with their own PC.The knowledge acquired through this book is of vital importance to investors because it allows them to judge independently on the risk of investing in this technology. It has been written for programmers because the knowledge of basics of computer science is useful to understand exactly what a quantum computer, once built, could be used for. But this understanding is also essential for investors who must evaluate whether and how much it is appropriate to risk investing in the development of quantum computing. Therefore, even investors (private investors, consultants, managers of financing funds for technological enterprises, etc.) who want to decide on the allocation of resources in quantum computing with full knowledge of the stakes, must know this book, and if they do not personally own the necessary prerequisites, they can use it by hiring some trusted computer expert to read it, understand it and report on the result.
