Happy Birthday Chuck!


Today was Charles Darwin's 200th birthday, or would have been if he hadn't dropped dead long ago. :-)

Serenity and I celebrated with some TVE Homeschool folks out in Livermore. Jenny set up a huge time line covering 3.8 billion years that was very cool. There was also a demonstration of the sexual aspect of natural selection using colored tiles which demonstrated that even though a trait like a bright color might make a species more susceptible to predation the increased success in breeding due to that trait can result in that trait driving out what would otherwise seem to be a better trait. Another demonstration used a variety of colored beans to demonstrate differences in survival rates under predation. Colored beans were scattered around the front yard and the kids "hunted" them down. Starting with 100 each of six different types we discovered, as expected, that large white beans were easy to locate and "capture" while the small green beans blended into the lawn never to be seen again ;-)

After the science there was cupcake and brownie eating followed by sugar powered running and playing. :-) A great time was had by all!

NBC anti-life?

I would boycott NBC, if I ever watched it that is. I actually never watch anything on the old line networks, NBC, CBS, ABC, FOX. Everything I watch is on the cable only stations... do they still broadcast over the air? Ah well, this story is about the fact that it seems NBC refused to air an ad put together by some Catholic outfit that features an embryo and all of the hardships it faced in early life ending up with the revelation that they were talking about Obama. Here is the ad , check it out and see how unoffensive it is. Like I said, if I watched them I'd quit now. :-/

Wikileaks and police state censorship

I saw an article today on SF Gate about some nit wit Bush appointed Federal Judge ordering a website I'd never heard of called Wikileaks shut down because they were publishing some bank documents from some corrupt Swiss bank. The amusing thing is that they can't actually do it! Even more amusing is that this just draws attention to the site and makes it that much more visible, yay idiot goons! :-) There are mirror sites all over the world and it's almost impossible for thuggish police state goons to figure out how to close off all of the leaks :-) One mirror site is here: http://wikileaks.be/wiki/Wikileaks The US site they tried to close down is still here: http://88.80.13.160 "Cowardice asks the question, 'Is it safe?' Expediency asks the question, 'Is it politic?' Vanity asks the question, 'Is it popular?' But, conscience asks the question, 'Is it right?' And there comes a time when one must take a position that is neither safe,...

Child Driven Education

Here is a Ted Talk with Sugata Mitra on Child Driven Education... very unschooling-like I think.  :-)  I've seen videos of him before, this is an update on his research on letting groups of kids learn on the internet, mostly without any supervision at all.  Posted via email from The Angry Gnome
