In class I refer to the U.S. healthcare system as a Frankenstein monster: every time something doesn’t work properly, we add something new that usually doesn’t work properly either. Dawn Smit, writing at The EclectiSite has put together a nice... Continue reading

Maybe you don’t use multi-level lists. This is Word’s name for something that’s in an outline format: you know, maybe a roman numeral for sections, then a capital letter for subsections that are indented, and so on. Do note that... Continue reading

He passed away yesterday. Actually, I’m at a loss for words about how to even explain someone like this. Check out his Wikipedia page, and keep in mind that this guy was never accused of being a gadfly, but rather... Continue reading

Umm … North Korea negotiated directly with South Korea for access to the Winter Olympic Games, which start in less than 24 hours. For those not paying attention, it’s been years since the two talked amongst themselves. For close to... Continue reading

There’s new research out that meditation … doesn’t help that much.† Fair enough. But here’s the clinker: The most unexpected result of this study, though, was that the more positive results found for compassion had important methodological flaws. Compassion levels... Continue reading

If I blogged about every Grateful Dead release I liked, I wouldn’t get anything else done. Even so, the new “Dave’s Picks Volume 25, Broome County Arena, Binghamton, NY 11/6/77” is one for the ages.† Back in the days of... Continue reading

One thing I am super glad about is that Frank Reich got a (winning) Super Bowl ring, as offensive coordinator for the Eagles. Frank Reich was the backup when the Bills lost 4 Super Bowls in a row, and he... Continue reading

I am not a Patriots fan. I am not a Tom Brady fan. Heck, I haven’t been a football fan since the 20th century. But everyone watches the Super Bowl, right? Plus, I grew up a Buffalo Bills fan. The... Continue reading

Via DailyOverview: Yes, these are satellite images. I like the next one better, although I do wish it had been taken at a time when the vegetation was more vibrant: A larger version of this can be saved from this... Continue reading

Important parts of my childhood were spent at a resort in the off-season. There was not much to do sometimes. Somewhere in the rainy autumn of 1979 or 1980 I bought a book there, trying to recreate the feeling of... Continue reading

Bad news. Washington D.C. is the only one of the 10 largest metropolitan areas in the U.S. with more economists than chefs. It is also one of two with more economists than people who call the clergy their full-time job.... Continue reading

This is very clever: The big insight — which no one told me about until I was about 45 (even though I’m a math nerd) — is that the square of a number is literally a square geometrically. Thus the... Continue reading

Pete Saunders: Chicago may be better understood in thirds — one-third San Francisco, two-thirds Detroit. As a visitor (in 2009, 1998, and 1988), I’ve stayed mostly inside the loop, and loved Chicago. But Shameless is one of my favorite shows,... Continue reading

An experimental archaeologist writes a lot about hominins knapping stones. But he also makes a case that sticks are a lot more important, but necessarily missing from the fossil record. I wish there was more here (but maybe there really... Continue reading

Dolphins can be trained. In study centers, they train them to clean litter from their tanks: find litter, bring it to a trainer, get a fish. Simple, right? The discussion below will fit in best with the last third of... Continue reading

What was Georgia thinking? I’ve watched that last play by Alabama — in slow-motion from behind the quarterback — about 20 times now. A lot of people blame Georgia’s “cover 2” defense. Maybe, but I don’t think so. In cover... Continue reading

Fairly early in microeconomics you learn that the problem with externalities is that the marginal social cost and the marginal private cost need not be the same, and this is the source of problems. The same goes for marginal social... Continue reading

Tim Worstall makes the point that drug legalization is now about quality control: the stuff is so strong that it better be dosed in a lab because it’s close to impossible to do on the street. Fentanyl related deaths are... Continue reading
