Good Morning!

I've been reading George Lakoff's book,  The Political Mind, Why You Can't Understand 21st-Century American Politics with an 18th-Century Brain.   Empathy is the key here, the key for the Democrats to win the election.  I'm glad Barack is taking a break, and hope he is reading this book.

I stayed awake for the meteor showers and kept getting up and now I see I had the wrong night.  It was worthwhile though as the stars, and the moon while it was up, were exquisite.

I'm startled by this with Georgia and Russia.  Georgia expects us to support them, and we are not there.   One of the many things that bothered me about the war in Iraq was we were using up our reserves.  What do we now have to offer?

Know that the George Lakoff book requires a strong stomach as to our actions.  It's nothing new, and it is always difficult to read it all bunched together.

Amidst it all, enjoy a beautiful day, and savor the steps.  We walked to The Buckeye yesterday for brunch and I savored the thrill of the bounce in my steps.   Walk on dirt.  It gives the most beautiful interaction with earth.

Invisibility -

I am trying to understand all this with Georgia and Russia and seem to be boggled.  I am going to slip into my invisibility cloak.

Scientists closer to developing invisibility cloak

Scientists say they are a step closer to developing materials that could render people and objects invisible.

Researchers have demonstrated for the first time they were able to cloak three-dimensional objects using artificially engineered materials that redirect light around the objects. Previously, they only have been able to cloak very thin two-dimensional objects.

The findings, by scientists at the University of California, Berkeley, led by Xiang Zhang, are to be released later this week in the journals Nature and Science.

The new work moves scientists a step closer to hiding people and objects from visible light, which could have broad applications, including military ones.

People can see objects because they scatter the light that strikes them, reflecting some of it back to the eye. Cloaking uses materials, known as metamaterials, to deflect radar, light or other waves around an object, like water flowing around a smooth rock in a stream.

Metamaterials are mixtures of metal and circuit board materials such as ceramic, Teflon or fiber composite. They are designed to bend visible light in a way that ordinary materials don't. Scientists are trying to use them to bend light around objects so they don't create reflections or shadows.

It differs from stealth technology, which does not make an aircraft invisible but reduces the cross-section available to radar, making it hard to track.

The research was funded in part by the U.S. Army Research Office and the National Science Foundation's Nano-Scale Science and Engineering Center.
