Interesting article on math edu. Also there is this nice quote:

In the words of Michael Jordan: “I’ve missed 3,000 shots. Twenty-six times the game-winning shot has been trusted to me, and I’ve missed. I’ve lost over 300 games. I’ve failed over and over and over again, and that is why I’ve succeeded.”

This is why I talk about 'math fitness'. People aren't bad at math; they are out of shape. We can all get (mathematically) in shape. We may not all go to the Olympics, but we can get in shape.

Nice mate-in-2 due to Oskar Blumenthal, thanks to the futilitycloset.com. The solution isn't hard but the composition is clever. For more on Blumenthal, see this:

The writing addiction, but Maryalnd author Bud Sparhawk:
The writing urge is enticing, enthralling, and at times frightening. You might begin on impulse, trying to relieve an itch with the point of a Number 2 yellow pencil and a pad of lined paper. It's not too hard, you imagine ...

Nice mate in 2 due to Orest Jewetzky, thanks to the futilitycloset.com. I can't find a date for this but I think it was created around 1900-1910.

Pretty funny when you think about it.
Our brains fool us all the time. And we typically have no idea that it’s happening.

Whoa
See also Scott Hanselman's blog here I'm in San Francisco this week, attending Microsoft's Build developer conference, as a sponsored guest of Microsoft. That's perhaps a bit odd for me, as I hadn't used Windows in nearly 1...

Interesting description of studies of how college student's moral behavior changes.
Efforts to make another person more generous or less arrogant may prove pointless, according to studies that find moral character is fairly stable.

I have used All for the Pet for years and never once had rude service. The store doesn't even open until 9am and Lisa often comes in early to help out people who want to drop off their pet before going to work. I think she does a good job with my pets and her prices are reasonable.
