From the New York Times…..

Only now, applying high-resolution imaging systems and three-dimensional X-ray tomography, have experts been able to decipher inscriptions and reconstruct functions of the bronze gears on the mechanism. The latest research has revealed details of dials on the instrument’s back side, including the names of all 12 months of an ancient calendar.

In the journal report, the team led by the mathematician and filmmaker Tony Freeth of the Antikythera Mechanism Research Project, in Cardiff, Wales, said the month names “are unexpectedly of Corinthian origin,” which suggested “a heritage going back to Archimedes.”

No month names on what is called the Metonic calendar were previously known, the researchers noted. Such a calendar, as well as other knowledge displayed on the mechanism, illustrated the influence of Babylonian astronomy on the Greeks. The calendar was used by Babylonians from at least the early fifth century B.C.

A full bus or trainload of people is more efficient than private cars, sometimes quite a bit more so. But transit systems never consist of nothing but full vehicles. They run most of their day with light loads. The above calculations came from figures citing the average city bus holding 9 passengers, and the average train (light or heavy) holds 22. If that seems low, remember that every packed train at rush hour tends to mean a near empty train returning down the track.

Transit vehicles also tend to stop and start a lot, which eats a lot of energy, even with regenerative braking. And most transit vehicles are just plain heavy, and not very aerodynamic. Indeed, you’ll see tables in the DoE reports that show that over the past 30 years, private cars have gotten 30% more efficient, while buses have gotten 60% less efficient and trains about 25% worse. The market and government regulations have driven efforts to make cars more efficient, while transit vehicles have actually worsened.

Lots of charts and graphs in the essay.

On the 4th of July, the extended family held a gathering at an RV campground in Pennsylvania. A pavilion was rented, food contributions lined up, and then the day arrived.
As it happened, I had been to the RV campground many years ago. Many years ago Grandma and Grandpa had a camper at the campground, and [click here to read more]

This personal narrative on the pursuit and application of college degrees reminds me of the importance of being educated (ranks right up there with the importance of being earnest). Usually stories like this end with “. . .and that’s why it’s so important to get a degree!” No wonder, because you need a college degree to figure out the logic of it.

Employers may have to reconsider the requirement of college degrees if credit continues to dry up as educational costs climb. Then again, it’s really more likely that we will print money to give to students so they can pay to go to college so that they can earn the money we printed for them.

Full disclosure: I got printed money in my back pocket.

The durian is “the fruit of trees from the genus Durio belonging to the Malvaceae, a large family which includes hibiscus, okra, cotton, mallows, and linden trees” So begins the wikipedia article. Blah, blah, blah, who cares. Right?

Well, sometimes the peculiar hides right in plain sight. Further on in the article, there was some very [Click here to read some more]

Anchorage Daily News….

Right now the so-called summer of ’08 is on pace to produce the fewest days ever recorded in which the temperature in Anchorage managed to reach 65 degrees.

That unhappy record was set in 1970, when we only made it to the 65-degree mark, which many Alaskans consider a nice temperature, 16 days out of 365.

This year, however — with the summer more than half over — there have been only seven 65-degree days so far. And that’s with just a month of potential “balmy” days remaining and the forecast looking gloomy.

Have you read that a new study proves that men and woman have equal ability in math and so the lack of woman in the hard sciences proves that woman are being held back? Then read this.

The report of the commission to assess the threat to the United States from Electromagnetic Pulse Attack is too long for most mere mortals to read. But everyone should at least make an effort to read chapter one (skip the introduction and scroll down to page 17).

The commission details how the US electrical grid has become increasingly vulnerable to all forms of disruption, not just EMP Attacks. Like the various reports that detailed the problems with the levees that held back the water around New Orleans, this report is going to be ignored. It will only receive widespread press once the grid goes down.

And as the report makes clear, the electric grid is very vulnerable and becoming more vulnerable with every passing day. Vulnerability to EMP attacks is simply the tip of the iceberg. An increasing shortage of black start capability combined with a shortage of parts means that simply blowing up a few key transformers could cause major problems.
