A Renaissance in Economics The American President Ronald Reagan once quipped, “The nine most terrifying words in the English language are, ‘I’m from the government and I’m here to help.’” I get the same shivers when someone introduces themselves as an economist.

The Nature of Computation
- Intellects Vast and Warm and Sympathetic
: "I hand you a network or graph, and ask whether there is a path through the network that crosses each edge exactly once, returning to its starting point. (That is, I ask whether there is a 'Eulerian' cycle.) Then I hand you another network, and ask whether there is a path which visits each node exactly once. (That is, I ask whether there is a 'Hamiltonian' cycle.) How hard is it to answer me?" (via

The New "Science" of Siblings
An amusing article from Time magazine by Jeffrey Kluger which reports that your siblings have more influece on your personality than any other group-- parents, peers, spouses, children, etc. My ex-wife thinks I'm sarcastic, combative, insensitive, etc. Do I get to blame my brothers and sisters for this now?
Another article on this issue "The Science of Siblings"

"If time has to end, it can be described, instant by instant," Mr. Palomar thinks, "and each instant, when described, expands so that its end can no longer be seen."

The False Controversy of Stem Cell Research.
Kinsley: In fact, thinking it through is a moral obligation, especially if you are on the side of the argument that wants to stop or slow this research.
It's not complicated. An embryo used in stem-cell research (and fertility treatments) is three to five days past conception. It consists of a few dozen cells that together are too small to be seen without a microscope. It has no consciousness, no self-awareness, no ability to feel love or pain. The smallest insect is far more human in every respect except potential.
