Process Fractal vs Geometry Fractals
Let proportion be found not only in numbers, but also in sounds, weights, times and positions, and whatever force there is.Leonardo Da Vinci The Mandelbrot set, seen here in an image generated by NOVA, epitomizes the fractal.

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…

Where is Our Starting Point?
“The end he (the artist) strives for is something else than a perfectly executed print. His aim is to depict dreams, ideas, or problems in such a way that other people can observe and consider them.” – M.C. Escher The Nobel Prize in Physics 1914 Max von Laue Quasicrystal: Prof. Dan Shechtman Can you trace…

Project Glass: I Can See Your Thoughts?
[youtube http://www.youtube.com/watch?v=9c6W4CCU9M4%5D We believe technology should work for you — to be there when you need it and get out of your way when you don’t. A team within our Google[x] group started Project Glass to build this kind of technology, one that helps you explore and share your world, putting you back in the…

Quantitative modeling of human brain activity
[youtube http://www.youtube.com/watch?v=KMA23JJ1M1o%5D Quantitative modeling of human brain activity can provide crucial insights about cortical representations [1,2] and can form the basis for brain decoding devices [3,4,5]. Recent functional magnetic resonance imaging (fMRI) studies have modeled brain activity elicited by static visual patterns and have reconstructed these patterns from brain activity [6,7,8]. However, blood oxygen level-dependent…

Thoughts On Dark Matter Search
A filament of dark matter has been directly detected between the galaxy clusters Abell 222 and Abell 223. The blue shading and yellow contour lines represent the density of matter. Image credit: Jörg Dietrich, U-M Department of Physics In light of direction LHC is experiencing there is always the questions of Oversight in terms…

Merging Galaxy Cluster Abell 520
Merging Galaxy Cluster Abell 520 This composite image shows the distribution of dark matter, galaxies, and hot gas in the core of the merging galaxy cluster Abell 520, formed from a violent collision of massive galaxy clusters. The natural-color image of the galaxies was taken with NASA’s Hubble Space Telescope and with the Canada-France-Hawaii Telescope…

EO: Earth Observatory
Twelve years after the Earth was buffeted by one of the more potent Sun storms in modern history, our nearest star crackled with activity again. A solar flare erupted on July 12, 2012, followed closely by a companion coronal mass ejection (CME)—a cloud of magnetically charged particles and energy that can disturb Earth’s magnetic field,…

Fermi Provides Insights?
[youtube http://www.youtube.com/watch?v=im-V5O0QDhI%5D There’s more to the cosmos than meets the eye. About 80 percent of the matter in the universe is invisible to telescopes, yet its gravitational influence is manifest in the orbital speeds of stars around galaxies and in the motions of clusters of galaxies. Yet, despite decades of effort, no one knows what…
