An equality between inertial and gravitational masses was established by Galileo Galilei more than 400 years ago and was accepted by Albert Einstein as a key point of his theory of gravitation — General Relativity. The above mentioned equality is called the Equivalence Principle. In this pioneering book, some unusual situations are described, where the Equivalence Principle is theoretically broken, and the possible experiments, where such breakdowns can be observed, are discussed in a brief. It is known that, in standard situations, the Equivalence Principle is extremely well established on Earth and in space in numerous experiments, including experiments during the recent space mission MICROSCOPE. Therefore, this book suggests a real breakthrough in the better understanding of Einstein's gravitational theory and its relation to quantum mechanics, which is a definite step towards the so-called 'Theory of Everything'. This book is recommended for all readers who are interested in gravitation and General Relativity.
The three volumes of the proceedings of MG15 give a broad view of all aspects of gravitational physics and astrophysics, from mathematical issues to recent observations and experiments. The scientific program of the meeting included 40 morning plenary talks over 6 days, 5 evening popular talks and nearly 100 parallel sessions on 71 topics spread over 4 afternoons. These proceedings are a representative sample of the very many oral and poster presentations made at the meeting.Part A contains plenary and review articles and the contributions from some parallel sessions, while Parts B and C consist of those from the remaining parallel sessions. The contents range from the mathematical foundatio...
This Worldwide List of Alternative Theories and Critics (only avalailable in english language) includes scientists involved in scientific fields. The 2023 issue of this directory includes the scientists found in the Internet. The scientists of the directory are only those involved in physics (natural philosophy). The list includes 9700 names of scientists (doctors or diplome engineers for more than 70%). Their position is shortly presented together with their proposed alternative theory when applicable. There are nearly 3500 authors of such theories, all amazingly very different from one another. The main categories of theories are presented in an other book of Jean de Climont THE ALTERNATIVE THEORIES
The Journal on Advanced Studies in Theoretical and Experimental Physics, including Related Themes from Mathematics
Following our preceding article, where we discussed alternative interpretations of the advanced perihelion of Mercury, the present article revisits the 1919 solar eclipse expedition led by Arthur Eddington, which famously provided the first observational confirmation of Einstein's theory of general relativity. We focus on the deflection of starlight data obtained during the eclipse, a cornerstone of this validation. Here, we explore three alternative explanations for the observed light bending that challenge the sole attribution to general relativity. Firstly, the paper begins by arguing based on criticisms raised by Tullio Levi-Civita, a contemporary mathematician, regarding Einstein's use ...
The Marcel Grossmann Meetings seek to further the development of the foundations and applications of Einstein's general relativity by promoting theoretical understanding in the relevant fields of physics, mathematics, astronomy and astrophysics and to direct future technological, observational, and experimental efforts. The meetings discuss recent developments in classical and quantum aspects of gravity, and in cosmology and relativistic astrophysics, with major emphasis on mathematical foundations and physical predictions, having the main objective of gathering scientists from diverse backgrounds for deepening our understanding of spacetime structure and reviewing the current state of the a...

This bang up-to-date volume contains the distilled wisdom of some of the world’s leading minds on the subject. Inside, there is a treasure trove of general (tutorial) and topical reviews, written by leading researchers in the area of organic superconductors and conductors. The papers hail from all over the world, as far afield as the USA and Australia. They cover contemporary topics such as unconventional superconductivity, non-Fermi-liquid properties, and the quantum Hall effect.
2012年4月6日,國際著名天體物理和宇宙學家、教育家、中國民主和人權倡導者方勵之先生在美國亞利桑那州(Arizona)圖森市(Tucson)去世,引起全世界各地,包括海峽兩岸三地的科學家和各界人士的沈痛哀悼。2012年4月14日在圖森舉行了隆重葬禮;同年10月初方勵之先生生前所任教的亞利桑那大學又舉辦了紀念方勵之科學學術會議。在這兩個活動上,方勵之先生的眾多同事、學生和親友們作了感人的發言或書面演講。在這些文章以及原有的一些關於他科學工作介紹的文章的基礎上,本書編輯委員會又向方勵之生前的科學方面的老師、海內外同事、學生、朋友和家人徵稿,請他們從方勵之先生對科學、教育、和人權的貢獻角度來回憶他們與他的交往,並匯集文稿編成此書。希望這本書能夠幫助讀者了解方勵之先生作為一個科學家的本色,以及他是如何從科學出發來影響中國的科技教育發展和社會政治改革,並為後人研究方勵之、研究中國和世界近現代史、近現代科技史保留一些珍貴的史料。
