Our Inconsistent Ethical Instincts
We like to believe that the principled side of the equation is rooted in deep, reasoned conviction. But a growing wealth of research shows that those values often prove to be finicky, inconsistent intuitions, swayed by ethically irrelevant factors. What you say now you might disagree with in five minutes. And such wavering has implications for both public policy and our personal lives. [more inside]

"Perhaps twenty or thirty people in England may be expected to read this book."
G.H. Hardy's review of Whitehead and Russell's Principia Mathematica
, published in the Times Literary Supplement 100 years ago last week. "The time has passed when a philosopher can afford to be ignorant of mathematics, and a little perseverance will be well rewarded. It will be something to learn how many of the spectres that have haunted philosophers modern mathematics has finally laid to rest."

Bret Victor on WorryDream
The power to understand and predict the quantities of the world should not be restricted to those with a freakish knack for manipulating abstract symbols.
When most people speak of Math, what they have in mind is more its mechanism than its essence. This "Math" consists of assigning meaning to a set of symbols, blindly shuffling around these symbols according to arcane rules, and then interpreting a meaning from the shuffled result. The process is not unlike casting lots.

Since 1980, Nikoli^
has been in the business of creating many different variations
of logic puzzles (such as the very popular Sudoku and Kakuro). Unfortunately, as they're stationed in Tokyo, their magazine is unavailable to most Americans.
Luckily, over the decades they've inspired quite a few people to make their own puzzles and variants, including:

Apparently there's at least a 51% chance of God's existence. It starts out 50/50, like with pets. You have, say, either a dog or a cat. It's a 50/50 chance that it's one or the other, just like it's 50/50 that there's a God or not. Well, we exist. You exist. The earth exists. That nudges it up to 51%. If I understand this youtube gentleman
. Hilarious exercise in smug delivery of ironclad logic.

Some are calling it the "Kindle Killer".
(Demo launch video at engadget
.) Plastic Logic's new e-reader, expected to be out in the first half of 2009, does promise to offer a lot that Kindle and most other other popular e-readers don't, like a larger display, big enough to provide a newspaper or magazine layout; touch-based markup and annotation; the ability to read standard documents and other file types without conversion; (promised) Wi-Fi connectivity (including the ability to transfer documents between readers); and last but not least, a screen display that you can hit with a shoe
, and isn't that something we've all been waiting for during these tense times? [more inside]

A mindbending logic puzzle.
A thousand people on the island, 900 brown-eyed and 100 blue-eyed; anyone who learns their own eye color must kill themself the next day; a visitor mentions that there is a blue-eyed person on the island; what happens? Nothing, you say, because they already know that? Wrong. Further details at the Terry Tao post linked above, but don't scroll down below the boxed description unless you want hints and/or spoilers.
