Collatz Conjecture

This is just so very cool I had to share it. I found this on the xkcd store while browsing around...
I love strange math ;-)

Collatz Conjecture

<< 1 / 2 >>

This shirt is based on the chains of numbers that make up the fascinating Collatz conjecture (also known as 'hailstone numbers'). The conjecture states that if you take any number, and if it's even you divide it by two and if it's odd multiply it by three and add one, and you repeat this process indefinitely, no matter what number you start with, you will always end up at 1. The tree in the shirt shows the route that various numbers take to reach 1.

The conjecture remains stubbornly unproven, and written in small letters at the base of the tree in the shirt is a quote about the conjecture attributed to Paul Erdos - "Mathematics is not yet ready for such problems."

The Tea Parties

I didn't make our local Tea Party , but it pulled hundreds of people as well... Tea, anyone? from Father Hollywood by Father Hollywood Like hundreds of thousands of other Americans, the Hollywoods enjoyed a tea party this past Wednesday. "Tea party" (wink wink). Nothing subversive about sipping a little Darjeeling, eh wot? Nothing to see here, Miss Napolitano. Anyway, our local festivities were held at Veterans Memorial Boulevard in Metairie. There were literally thousands of people crammed into the neutral ground (though on that day, the ground was anything but...), as cars and trucks poured by the busy boulevard laing on their horns in support. Here are pictures. And like every such gathering in our environs, there was even a brass band and an improptu "second line" parade. It was a "party" after all. But it was a party with a serious reason. The crowds were so overwhelming that it was hard to hear the speakers, and unfortunately, we did have a fe...

Viva California! USA out of California Now!

Gene Veith points to a Russian who predicts the breakup the American Empire. Gene is somehow unaware of the dozens of secessionist movements in various states. Granted they are almost all small but still, they exist and this could be a good time for us. Those who know me already understand that I'm a California Nationalist who I doesn't think California should have joined those united States in the first place. Being a part of that empire just costs us money, we get nothing in return. These days we get to be hated by foreigners for being Americans and mocked by Americans for being Californians. Getting us out of the US yesterday would be a day too late as far as I'm concerned.

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
