Gérard Siegwalt est né en 1932. Professeur émérite de théologie protestante à l'Université de Strasbourg, auteur d'une somme théologique originale et sans équivalent dans le monde francophone récent, il est l'un des grands penseurs protestants contemporains. Cet ouvrage évoque plusieurs de ses thèmes majeurs et en propose un axe d'interprétation. Il en montre la diversité, la pertinence actuelle et le profond intérêt humain. Au fil de l’exposé, se dessinent ainsi les contou...

To understand the physics of Black Holes, it is important to understand the first law in Physics which controls our entire universe. This is the law of “Perfect Equilibrium”. Within the entire universe there is always a prefect equilibrium between all the physical forces like gravity, forces of inertia, radiation pressure and Electro-Magnetic Interaction forces at any time, in any direction and at any space coordinate. This is the fundamental law in physics on which also the existence of ...

According to Maxwell’s equations Electromagnetic Waves can only propagate along straight lines and it is impossible that Light (Electromagnetic Waves) could confine with the surface of a sphere or an ellipse. For that reason, these material waves in Schrödinger’s wave equation could only be of a different origin than Electromagnetic Waves. Niels Bohr introduced the concept of “Probability Waves” as the origin of the material waves in Schrödinger’s wave equation. And defined the Ne...

Guided practice helps students develop into expert problem solversThe new 15th Edition of University Physics with Modern Physics, now in SI Units, draws on insights from several users to help students see patterns and make connections between problem types. Students learn to recognize when to use similar steps in solving the same problem type and develop an understanding for problem solving approaches, rather than simply plugging values into an equation. This edition addresses students' te...

Focus on the fundamentals and help students see connections between problem types Richard Wolfson's Essential University Physics is a concise and progressive calculus-based physics textbook that offers clear writing, great problems, and relevant real-life applications in an affordable and streamlined text. The book teaches sound problem-solving strategies and emphasises conceptual understanding, using features such as annotated figures and step-by-step problem-solving strategies. Realising st...

Dark matter theories build strongly on curve fitting to get the picture right.

MOND does not teach us anything about the underlying physics responsible for the described results.

Our alternative with a different angle of approach which was born from establishing a new causal principle for gravity. The resulting discrete model of compressed quanta leads to the equivalent of a galaxy as a Rankine vortex with a central spinning black hole, with stars as co-rotating particles with a rotational ...

Wat is de samenhang tussen ruimte, tijd en materie? In de twintigste eeuw zijn eeuwenlang gekoesterde ideeën over ruimte, tijd en materie overboord gegaan en bleek de werkelijkheid vreemder te zijn dan onze alledaagse ervaring ons influistert. In dit boek lees je hoe de fundamentele natuurkunde ons beeld van de werkelijkheid heeft bijgesteld en worden vragen beantwoord als wat de rol van wiskunde in de natuurkunde is, hoe een knikkerbaan dwars door de aarde zich verhoudt

tot een kwantumveld,...
