Mathematics versus The Blob

by

(…and so far, the blob seems to be winning)

Here’s a New York Daily News article on mathematical ignorance among City University of New York students:

During their first math class at one of CUNY’s four-year colleges, 90% of 200 students tested couldn’t solve a simple algebra problem, the report by the CUNY Council of Math Chairs found. Only a third could convert a fraction into a decimal.

And here’s Sandra Stotsky, discussing some of the reasons for poor math performance in America’s schools:

But the president’s worthy aims (to improve math and science education–ed) won’t be reached so long as assessment experts, technology salesmen, and math educators—the professors, usually with education degrees, who teach prospective teachers of math from K12—dominate the development of the content of school curricula and determine the pedagogy used, into which they’ve brought theories lacking any evidence of success and that emphasize political and social ends, not mastery of mathematics.

Power: Mechanical, National, and Personal

James Boswell is of course best known as the great biographer of Samuel Johnson. But Boswell didn’t spend all his time in Dr Johnson’s company. In 1776, he visited the Boulton & Watt steam engine factory. Showing Boswell around, Matthew Boulton summed up his business one simple phrase:

I sell here, sir, what all the world desires to have–POWER.

Fast forward to 2009. In the United States as in Western Europe, politicians are conducting a vendetta against the energy industry. See for example this, which describes the closure of an aluminum smelter in Montana–because it can no longer obtain affordable electricity–and the probable exit of much of the nonferrous metals industry from Western Europe, for the same reason.

So, was Matthew Boulton wrong? Have we finally found a group of humans–our present-day political leaders–who are NOT interested in power?

Sloppy PC security leads to people being framed as downloading child porn. Of course, if you are a pedophile, you want to use a Windows machine so you have the handy, “a hacker did it!” excuse.

I was vaguely aware of the Martin Mars, a very large seaplane built in the 1940s for the U.S. Navy…but had no idea that any of these airplanes were still flying in commercial service.

Turns out that two of these planes–the Hawaii Mars and the Philippine Mars–are in regular use as water bombers for forest-fire fighting. Tailspin Tom has a great set of photographs.

Via Neptunus Lex, who notes that the Mars is less a flying boat than a flying ship.

Entrepreneurship in Decline?

by

Michael Malone has been writing about the technology industry, and particularly about Silicon Valley, for a couple of decades. This recent article is not very optimistic. Although Malone identifies several emerging technologies as having great potential, he fears that the basic mechanism by which new technologies are commercialized–the formation and growth of new enterprises–is badly broken.
