You are reading the word "now" right now. But what does that mean? What makes the ephemeral moment "now" so special? Its enigmatic character has bedeviled philosophers, priests, and modern-day physicists from Augustine to Einstein and beyond. Einstein showed that the flow of time is affected by both velocity and gravity, yet he despaired at his failure to explain the meaning of "now." Equally puzzling: why does time flow? Some physicists have given up trying to understand, and call the flow of time an illusion, but the eminent experimentalist physicist Richard A. Muller protests. He says...

We are entering a new technological era. In this world, we relate with ourselves and others in a clear, precise manner. In "Dwelling in a New World, " author Robert Gold introduces an invention that will provide an explosive expansion of our capacities and profoundly reorient us, growing our relations and awareness.

"Dwelling in a New World" reconstructs communication, technology, and accounting. Exploring what we have taken for granted, it tells of reinventing communication and our understanding of existence in order to gain an awareness of a direct connection with affinity, harmony,...

The book provides readers with an understanding of the mutual conditioning of spacetime and interactions and matter. The spacetime manifold will be looked at to be a reservoir for the parametrization of operation Lie groups or subgroup classes of Lie groups. With basic operation groups or Lie algebras, all physical structures can be interpreted in terms of corresponding realizations or representations. Physical properties are related eigenvalues or invariants. As an explicit example of operational spacetime is proposed, called electroweak spacetime, parametrizing the classes of the...

In physics, the idea of extra spatial dimensions originates from Nordstom's 5-dimensional vector theory in 1914, followed by Kaluza-Klein theory in 1921, in an effort to unify general relativity and electromagnetism in a 5 dimensional space-time (4 dimensions for space and 1 for time). Kaluza-Klein theory didn't generate enough interest with physicist for the next five decades, due to its problems with inconsistencies. With the advent of supergravity theory (the theory that unifies general relativity and supersymmetry theories) in late 1970's and eventually, string theories (1980s) and...

Raum und Zeit sind die grosse Buhne, auf der sich unser Leben und alle irdischen und kosmischen Vorgange abspielen.Meist erleben wirRaum und Zeit als unveranderlich und unbeeinflussbar. Doch Raum und Zeit konnten Eigenschaften haben, von denen selbst Einstein nicht zu traumen wagte. Andreas Muller erlautert unser modernes und hochst faszinierendes naturwissenschaftliches Weltbildund stellt das erfolgreiche Konzept der Raumzeit vor, das vor gut hundert Jahren von Albert Einstein begrundet wurde.Daruber hinaus fuhrt er den Leserbis zu den spannendsten Fragen der Gegenwart: Gibt es mehr als...
