Relativity free of Folklore #7
When Celestial Dynamics becomes Kinematics Again - General Relativity
This e-book corresponds to Chapter 7 of the printed book entitled "Galloping with Light - Einstein, Relativity, and Folklore", and is the number 7 of the e-Series entitled "Relativity free of Folklore".
Because you deserve more than just folklore, in this e-book you will find the surprising answers to the following intriguing questions:
1) Why do we see the astronauts weightlessly floating inside the International Space Station, when at the altitude of about 350 Km where the Station is, Earth gravity is of course very strong and it is precisely (according to Newton) the reason why the station keeps rotating?
2) Why is “General Relativity” referred to as a Theory of Gravitation? What does Gravity have to do with Relativity?
3) What does it really mean to say that gravitation and acceleration are equivalent?
4) Is the Twin Paradox a real paradox? If motion is relative, why is the traveler twin the one that is younger when they get together and not the twin that stays on Earth?
5) Do you really age more slowly if you live on the first floor than if you live on the top of a skyscraper?
6) What is the relation between Relativity Theory and the GPS navigation technology in our cars?
7) Why was the Apollo 11 landing on the Moon so important for Relativity Theory?
The fact that the reader may not have a scientific education does not mean that s/he does not have the intelligence to understand profound concepts -- as long as they are presented with semantic and epistemological clarity. After all, Einstein said that Science is simply the refinement of our intuition and everyday experiences.

About the author
Felix Alba-Juez
13 books32 followersFelix was born in Burgos (Spain) in 1948. In 1949, his parents settled in Necochea (Argentina) where he completed his elementary and high school education. In 1966 he moved to Bahía Blanca (Argentina) where he graduated in Electrical Engineering at the 'Universidad Nacional del Sur' (UNS). In 1971, he started his academic life as Teaching Assistant of Mathematics at the UNS and, from 1974 until to 1983, he was Adjunct, Associate, and Full Professor at the 'Universidad Nacional de San Juan' in San Juan, Argentina.
In 1983, he moved to Salt Lake City, USA as Postdoctoral Fellow and soon after Research Associate for the Department of Metallurgy at the University of Utah, conducting basic Research and Development on Optimal Control of Mineral Grinding Operations.
In 1987, he left Academia and founded his own consulting company working over the years with private companies and governmental entities as DuPont, ALCOA, US Department of Transportation, NASA, and Dow Chemical. His first patent was granted in 1992 in USA, United Kingdom, France, Germany, and Japan, protecting a technology based on ultrasonic spectroscopy for measuring particle size in industrial suspensions and emulsions.
In the period 1997-2001, Felix developed a fundamental theory for the generic mathematical modeling of multiple scattering of optical and acoustical waves interacting with highly-concentrated suspensions and emulsions.
During 2001-2007, he developed a particle size analyzer based on optical spectroscopy, and commercialized a generic simulation software tool connectable to acoustic and optical spectrometers, so as to convert them into particle size analyzers. The patent for this generic technology was granted in 2007.
In 2008, Felix sold all his intellectual property to Agilent Technologies, Inc, and currently is a scientific consultant, and writes Popular Science books on Epistemology and Philosophy of Science in English and Spanish. His first book in Spanish on the Theory of Relativity was published in 2009 by the 'Ciudad de las Artes y las Ciencias, S.A.' in Valencia (Spain).
Since October 2013, Felix is back to Academia as a Research Professor for the Department of Metallurgical Engineering of the University of Utah. He is also working on the e-series 'Quantum Physics free of Folklore' of which 'Records of the Future' is its first volume published in January 2013.

En 1983, se trasladó a USA donde se desempeñó como 'Post-Doctoral Fellow' y luego 'Research Associate' en el Departamento de Metalurgia de la Universidad de Utah, conduciendo investigación básica en teoría del control óptimo, y asesorando a estudiantes de doctorado en el control óptimo de la molienda de minerales.
En 1987, se estableció como consultor independiente trabajando para entidades como DuPont, ALCOA, Dow Chemical, 'US Department of Transportation', y NASA. Su primera patente fue otorgada en 1992 en USA, Inglaterra, Francia, Alemania y Japón, protegiendo una tecnología de medición de tamaño de partícula basada en espectroscopia de ultrasonido.
Durante 1997-2001, desarrolló una nueva teoría física para modelar genéricamente la reflexión, refracción, difracción, y absorción múltiple de ondas ópticas y ultrasónicas interactuando con suspensiones altamente concentradas.
En el período 2001-2007, desarrolló un analizador de tamaño de partícula basado en espectroscopia óptica, y comercializó una herramienta de simulación genérica para conectar a espectrómetros

Excellent! Extraordinarily clear and real!
As the questions in the "Book Description" for this Chapter give the potential readers good insight into its contents, all I have to say here is that the answers are crystal-clear, supported with an excellent review of experimental tests and proofs, and wonderfully well associated with our everyday experience.
I am delighted with the manner in which the physics phenomena associated with the gravitational field (e.g. gravitational time dilation/red-shift and deflection of light) are illuminated.
What impressed me most is the author's ability to make a non-mathematical person like me interested in and capable of understanding the concepts behind the physics terms and mathematical expressions/equations necessary for undistorted comprehension of the reality described by the Relativity Theory.
I find this kind of approach extraordinarily efficient. It helps the general reader to get rid of misconceptions and teaches him/her how to think of the physics notions such as the non-Euclidean space-time, gravitational field variable in time, the Principle of Equivalence, etc, in the way that makes perfect sense.
VERY HIGHLY RECOMMENDED!!!
