It means what educators and others have been saying -- that critical thinking and higher order thinking skills can be taught. And we're doing a better job now of teaching them because we understand better what they are.

My lenovo laptop bluescreens on suspend running Windows 7, and Microsoft hasn't fixed it yet. Does that mean Microsoft ceases to be credible?

On the other hand, I've tried on a few occasions to share an MS doc on Google Docs, and Google Docs has failed catastrophically with a "file too complex" message. And, they aren't all that complex. Just long, with embedded hyperlinks and extended bibliographies (e.g. any typical scholarly journal article with a reasonably complex linked references list). The reality is, Google Docs is good for some simple things and decidedly underpowered for other more complicated tasks. I have lots of docs Google Docs simply can't handle.

No question, these are the books you want. From the publisher's description: Product Description "aha! Gotcha" and "aha! Insight" are here combined as a single volume. The aha! books, as they are referred to by fans of the author Martin Gardner, contain 144 wonderful puzzles from the reigning king of recreational mathematics. In this combined volume, you will find puzzles ranging over geometry, logic, probability, statistics, number,time, combinatorics, and word play. Gardner calls these puzzles aha! problems. He explains that aha! problems "seem difficult, and indeed are difficult if you go about trying to solve them in traditional ways. But if you can free your mind from standard problem solving techniques, you may be receptive to an aha! reaction that leads immediately to a solution. Don't be discouraged if, at first, you have difficulty with these problems. Try your best to solve each one before you read the answer. After a while you will begin to catch the spirit of offbeat , nonlinear thinking, and you may be surprised to find your aha! ability improving." Studies show that persons who possess a high aha! ability are all intelligent to a moderate level, but beyond that level there seems to be no correlation between high intelligence and aha! thinking. So dig into some of the puzzles in this book, and prepare yourself for an aha! experience. Book Description Previously published separately, the two books aha! Gotcha and aha! Insight are here combined as a single volume. The aha! books, as they are referred to by fans of the author Martin Gardner, contain 144 wonderful puzzles from the reigning king of recreational mathematics.

Hm. So someone puts a printout of the license plate of my lexus on a junker honda and ... Gee, I think I'd notice when I got the citation with a printout of the photo. I smell hoax or urban myth.

No, it doesn't. Zoom in and you can see the blur line where it crosses the parking lot. On one side, you can see the parking striping and individual lights; on the other at highest magnification, gray fuzz.
