Glass half full?

by | Sunday, September 14, 2008

Just discovered a great riddle/puzzle site: [wu:riddles].

As the site says:

The riddles are organized by difficulty … easy, medium, and hard. Then there is the microsoft section, consisting of weird, open-ended consulting-style questions. The cs and putnam sections contain problems which may require a particularly specialized background in computer science and mathematics

Browsing around in the easy section (that was tricky enough for now) I came across some really nice ones. Check out Glass Half Full and Infinite Quarter Sequence.

Jul 9, 2023

What is this thing called learning? What does it mean to learn something? What makes us want to learn? Why is it fun? Why do we want to know? Even as educators, we often don't take the time to ask ourselves these foundational questions. So it is rewarding when we get...

Aug 9, 2011

This morning I was at the doctor's office and picked up a dated (February, 2011) New Yorker magazine and discovered a great essay by Adam Gopnik: The Information: How the Internet gets inside us. I am not sure how I missed this the first time around but Gopnik does a...

Back from India…

The Allegory of the Cave

Feb 17, 2009

Plato's Allegory of the Cave (see Wikipedia entry) illustrates "our nature in its education and want of education." It is maybe one of the most famous allegories in literature and philosophy, a precursor to the kinds of mind-games (think brain in a vat) that...
