This simple and elegant physics experiment makes me wish I could show this device to a classroom full of children.

My wife asks my son Ben, "What's going on in your head all the time when you are so quiet?" My son says; "It's pretty much Star Wars all the time, Mom!" I'm watching a TV show about cosmology, including the possibility of multiple universes. My son has sneaked to the couch across the room and pipes up; "Dad, does that mean that there REALLY could be a Star Wars universe?" he asks. I ask, "What did you just hear about the possibility of multiple universes?" "That there could be more than one universe," he says. "So.....?" "Cool!" he says. "There really COULD be a Star Wars universe!" I immediately chased Ben off to bed. Now and again I hear Ben say, "That defies the laws of physics, except in a Star Wars or other universe!"
In 2009, James Randi declared that homeopathy qualified for his million dollar challenge. He said then
Homeopathy DOES NOT WORK. It's quackery, pure and simple. It's a farce, a fake, and flummery. Prove it works, and win the million dollars.On Saturday, February 5th, he released a statement challenging the homeopathic manufacturers to submit to a double blind test and to the retail outlets to label the products for what they are - NOT MEDICINE! Erich posted a piece “Overdosing on homeopathic drugs” last May which has enough links for someone to see for themselves how absurd this concept is. By their philosophy, we should all be sick from some harmful strain of e. coli because at some point all water has been touched by such, and it will, of course retain that memory. Or does it only retain the memory of the “good” stuff? Go get ‘em, Mr. Randi!
My favorite line in this short video discussing deep field images: These images are all contained in an area as big as a grain of sand at arm's length.
As Darwin Day approaches (February 12), it is obvious that times are changing. America may be getting ready to face the Enlightenment, only a few centuries after our founders tried to encapsulate its principles in our government.
On HuffPo, Paul Pardi recently wrote Religion is Evolving Before Our Eyes, about how American Fundamentalism and even Protestantism in general is suffering from ubiquitous communication. Few kids are exposed to only one point of view any more, so they are more likely to spot the discomforting inconsistencies of any given dogma. Small churches are closing their doors for lack of parishioners, and mega-churches pander to the basest prejudices just to pay the bills.
But on NPR, in the wake of Obama's "Sputnik Moment" comment, Ursula Goodenough wrote It's Time For A New Narrative; It's Time For 'Big History' as a plea to create a more evocative narrative for science, to better win hearts to engage their minds. This is a real problem, as those best trained to understand an issue are rarely well equipped to explain it from the ground up. We need Sagans and Tysons for every school district; those who can evoke the excitement of understanding the universe.
More and more people are turning away from their ancestral religions. Too many toward New Age woo, and some toward rationality. So the marketing arms of the churches work feverishly. They know that rational families tend to stay that way, but woo begets woo, and can be won back to the fold. They tirelessly try to pass laws to insert a religious wedge in science and history classes.
Several states currently have bills pending to make it harder to teach 19th and 20th century biology or geology by inserting stories from ancient texts that contradict every discovery of the last 200 years.
Here is a link with a list of current bills to establish anti-evolution state laws. Missouri, Kentucky, New Mexico, and other states all have at-risk public school syllabi. This may be a desperate last gasp of Fundamentalist anti-intellectualism. Or their fast grasp of schools could succeed, and leave America behind as other nations quickly accept the progressive mantle we are letting slide from our shoulders.
One could see this as the epic battle of the end times. But it is not the world ending, but an ancient and arguably obsolete world view. But the battle may be a messy one. The forces of ignorance are tireless and prolific. After all, an unreasoning populace is easier to lead.
