You're such a BOSON!

Reports are out. They have finally found the mysterious Higgs Boson, or the "God Particle" (apparently, derived from "Goddammed Particle").
What is this Boson? Below is an excerpt from http://physicsforme.wordpress.com/2011/07/24/higgs-boson-one-page-explanation/ , where several explanations for the Higgs Boson are posted. I found this one relatively simple, if you have a high school physics background...and actually remember it:

"The Need to Understand Mass

By Roger Cashmore Department of Physics, University of Oxford, UK.

What determines the size of objects that we see around us or indeed even the size of ourselves? The answer is the size of the molecules and in turn the atoms that compose these molecules. But what determines the size of the atoms themselves? Quantum theory and atomic physics provide an answer. The size of the atom is determined by the paths of the electrons orbiting the nucleus. The size of those orbits, however, is determined by the mass of the electron. Were the electron’s mass smaller, the orbits (and hence all atoms) would be smaller, and consequently everything we see would be smaller. So understanding the mass of the electron is essential to understanding the size and dimensions of everything around us.

The beauty of Martian Landscaping

In a previous post, I mentioned the use of Utah's Plateaus and Canyons to illustrate the Landscape of Mars (Barsoom) in Disney's John Carter.

As some of you may know Mars has just been the closest to Earth it will be for quite some time. If you are like me, you did not possess a telescope powerful enough to get a  glimpse of the martian terrain. Luckily, The University of Arizona  Department of Planetary Sciences/Lunar and Planetary Laboratory's HiRISE, the High Resolution Imaging Science Experiment, has and will continue to capture high resolution images of Mars that we can view on their website . I highly recommend sharing these wonderful photos with the budding astronomer in your family!
