Brian Clegg: Gravity
A history of gravity, and a study of its importance and relevance to our lives, as well as its influence on other areas of science. Physicists will tell you that four forces control the universe. Of these, gravity may the most obvious, but it is also the most mysterious. Newton managed to predict the force…

Weber Bars Ring True?
Gravitational Radiation Gravitational waves have a polarization pattern that causes objects to expand in one direction, while contracting in the perpendicular direction. That is, they have spin two. This is because gravity waves are fluctuations in the tensorial metric of space-time. How would you map this above? WMAP image of the Cosmic Microwave Background Radiation…

The Universe Time Travel
The mystery of time travel is explored as we embark on an adventure to reveal if traveling into the future will one day be a reality. Next we examine if traveling into the past will have bizarre consequences. Finally, are scientists on the verge of discovering an Earth-like planet within the next few years? The…

Gravity is Talking, LISA will Listen
It seems by measure the Interferometer has come a long way. If one recognizes how gravitational waves are measured, you come to understand how they can have a affect on laser light. Bee and Stefan of Backreaction have gone to visit the historical location of the beginnings of how we use interferometers. (click on Image…

Correlating Gravitational Wave Production in LIGO
Drawing by Glen Edwards, Utah State University, Logan, UT The most important thing is to be motivated by your own intellectual curiosity.KIP THORNE *** Fig. 1. The four forces (or interactions) of Nature, their force carrying particles and the phenomena or particles affected by them. The three interactions that govern the microcosmos are all…

Leaving Footprints
Labyrinth on the portico of the cathedral of San Martino at Lucca, Tuscany, Italy. The term labyrinth is often used interchangeably with maze, but modern scholars of the subject use a stricter definition. For them, a maze is a tour puzzle in the form of a complex branching passage with choices of path and direction;…

What are Memories made up of ?
Illustration by The New York Times Some do indeed understand the fuzzy logic. These images are pixel orientated. They describe a process of thinking that is quite impermeable to the everyday biological function of the thinking brain that we have devised a way in which to represent the process of marketing for the populace at…

Stargazers and Hill Climbers
AS with Einstein, who was Socrates daemon?:) In Plato’s Apology of Socrates, Socrates claimed to have a daimonion (literally, a “divine something”)[6] that frequently warned him – in the form of a “voice” – against mistakes but never told him what to do See:Fullerane and Allotropes Some may even call “hills” mountains. Depends on where…

Gran Sasso and the Pyramid
What good is a universe without somebody around to look at it?Robert Dicke This summer, CERN gave the starting signal for the long-distance neutrino race to Italy. The CNGS facility (CERN Neutrinos to Gran Sasso), embedded in the laboratory’s accelerator complex, produced its first neutrino beam. For the first time, billions of neutrinos were sent…

Time is Like a River
How can a speck of a universe be physically identical to the great expanse we view in the heavens above? (Greene, The Elegant Universe, pages 248-249) As Alice learned, it’s not always clear what’s a looking glass, and what’s a window to another world. Mirrors and windows are often interchangeable: we look out into the…
