Sailing the Last Voyage with Newton and Pascal
To prevent fiascos like this, which took place earlier today at the University of Tennessee at Chattanooga: Due to a scheduling error by a staff member in one of our emergency response offices, the test of our system occurred at 12:12 a.m. instead of 12:12 p.m. This was a case of simple human error. We …

This from Rusty Signor, current President of the Pile Driving Contractors Association and President of TX Pile, LLC, in the current issue of Pile Driver: In my last message, I ended with a different, more positive view on the news in our current world situation. This time, I am going to do another first: a …
It's been a long time since many computers ran DOS or even Windows 3.1. Given the changes in hardware, it would be difficult to get most any recent PC to run one or both. Yet every time we have a major software upgrade, we lose some of the capabilities we had in the past. It's …

Anyone who blogs has persistent commenters. Last year my "top" commenter was one David Lloyd-Jones, a Canadian who took exception to a great deal of what I wrote (although not everything he read). Lloyd-Jones found me via my series of my business dealings in China in the early 1980's. He himself has had an interesting …

And it's about to kill him: America's best-known public-opinion guru hasn't suddenly gone vegan. Luntz—the tubby, rumpled guy who runs the focus groups on Fox News after presidential debates, the political consultant and TV fixture whose word has been law in Republican circles since he helped write the 1994 Contract With America—has always been a …
In this case, the legalisation of marijuana, according to Rod Dreher: Opponents of marijuana among the elites are those who have maintained enough contact with Middle America — David “Bobos in Paradise” Brooks has this all over his résumé! — to realize that the experiences of élite urban Americans can’t be extended to all America …

Every New Year's Day, I try to get away from the usual run of topics and tackle something of longer-term interest. Last year it was gun control; the only thing that prevented this from becoming a larger player on our political stage was the ineptitude of the administration that wants to expand it. This year's …

From St. Thomas Aquinas' Summa Theologiae, 3 q. 2 a. 6: ...we must know that two heresies have arisen with regard to the mystery of the union of the two natures in Christ. The first confused the natures, as Eutyches and Dioscorus, who held that from the two natures one nature resulted, so that they …

Yes, a new gas tax can help our transportation system: The program is the federal Highway Trust Fund, which pays about half the yearly tab to build and maintain the nation’s roads, bridges and rails. At the moment, the loudest advocate for fixing it responsibly is a liberal Democrat, Rep. Earl Blumenauer (Ore.). This month …
