$42,000 per flight hour that’s 7 switchblade drones per hour. It raises the question of whether the F35 would be cost effective if we got the planes for free (not $80,000,000 each ). Currently F35s manage on average 11.2 flight hours per critical failure (I got that one partly from memory and partly from googling [f35 11.2 hours]. For one thing, that raises the question of how many will be available when they are needed. For another how many...

First sex ratio disruption is an important general topic in population biology. An allele which causes I note that I have been (ignorantly) discussing this topic for more than 10 years “A disrupted sex ratio can, in principle, drive a species extinct. Consider an abnormal genome which causes a male to produce only male sperm. This could, in principle spread through a population causing a shortage of females and reduced fitness. The key...

Why the public still views inflation as a major problem, despite the official numbers  – by New Deal democrat This is the topic I indicated last week I wanted to write about more at length.  Paul Krugman wrote last week about the disconnect between most economists, who see inflation declining, and voters, who still see inflation as a major concern. Here’s a couple of his tweets: As I wrote last week, the “shrinkflation” in new homes is very...

Hah got your attention there. The connection is Austrian-American actress Hedy Lamarr pionere of Cinematic nudity, Marine drone technology and the anti jamming anti interference technology on which WiFi is based. Notable for the first Hollywood full frontal nudity scene and the concept of an un jammable, uninterceptable, radio controlled torpedo. Lamarr was born in Austria and married a guy who owned a company which made torpedoes. Post WWI when...

It is agreed that freedom of speech does not imply freedom to make whatever performative utterance one chooses. It just isn’t agreed what “performative” means. Some (of whom you are the first I ever heard do so ever in my life) use it in this sense. The usage condemnation is performative when, for example a judge condemns one to death – the sequelae are nonverbal and very direct (much more so before the current practice of 7 years or so if...

There has been much laughter over the fact that Donald Trump has repeatedly given the impression that he thinks that stealth technology works at the wavelength of visible light, so stealthy aircraft are invisible. He isn’t the only one who is saying silly things based on ignoring wavelength. The technology used by the F117, F22, and F35 does not hide planes from world war II era radar. The old radar used long wavelength waves. They are reflected...

This is Part 1 of a three-part story of how politics and delays backed by commercial interests and business sponsor groups delayed and eventually killed a bill meant to aid Ohio citizens. Kind of a forerunner to what may happen if Congress ever promotes a bill for healthcare-for-all. I will post the other two parts over the next two days, We sought a cause of death for HB 135. We found it … and something far bigger, WSYX, Darrel Rowland Part 1...

The 2022 Globie: Money and Empire by Joseph Joyce Every year we name a book the “Globalization Book of the Year” (aka the “Globie”). The prize is (alas!) strictly honorific and does not come with a monetary award. But announcing the award gives me a chance to draw attention to a recent book—or books—that are particularly insightful about globalization. Previous winners are listed at the bottom of the column (also see here and here). This...

General Disclaimer: I don’t know what I am writing about. I am an economist not an electical engineer. This should go without saying, but just in case, remember that I don’t know what I am typing about. Radar is used to determine where airplanes are. One use is air traffic control for civil aviation — the airplanes cooperate. Another is military — hostile aircraft do not cooperate. First in civil aviation, the system is far removed from...

Why would I write of this event on an economics blog. Fourteen years of age and five years away from being in the service. I was very aware then and a freshman at Lane Tech an all boy’s high school in Chicago. It is economics in the rawest of forms. The suppression of an entire population in the South and in the North. Economic slavery . . . September 15, 2023 (Friday), Letters from an American, Prof. Heather Cox Richardson At 10:22 in...
