At this blog we have lots of smart Chicago Boyz and Chicago Grrlz and Readerz…but is anyone here as smart as a certain Chinese official from 1000 BC…or maybe even earlier?

Imagine that you are the official in charge of caravans and messengers. Some of these travelers need to cross an unmarked plain, which is subject to sandstorms, thick cloud layers, and heavy fogs…and they have frequently been getting lost. You need something that will aways point south. Problem: the magnetic compass has not yet been invented.

Can you think of a way–without using magnetic principles or other technology that wasn’t likely to be available in 1000 BC…to solve this problem? Think about it for a few minutes before reading further.

An Intersection of Technologies and Infrastructures

Obama has released his plan for the expanded development of passenger rail in America.

Best practice in high-speed passenger rail is, of course, to power it electrically, from overhead wires. And these things use significant amounts of electricity. A quick search reveals that a French TGV train draws somewhere in the range of 6-12 megawatts. (For comparison, 6 MW is the amount of power consumed by 60,000 regular incandescent 100-watt bulbs.)

Most of the electricity that runs the TGV, of course, comes from France’s extensive nuclear power system. It’s unfortunate that Obama, with his admiration for things European, is not paying more attention to France’s very successful experience with nuclear power.

Deadly Naivete – Updated

Jeffrey Goldberg, reporting in the Atlantic on an interview with Israel’s new prime minister:

“The Obama presidency has two great missions: fixing the economy, and preventing Iran from gaining nuclear weapons,” Netanyahu told me. He said the Iranian nuclear challenge represents a “hinge of history” and added that “Western civilization” will have failed if Iran is allowed to develop nuclear weapons.

In unusually blunt language, Netanyahu said of the Iranian leadership, “You don’t want a messianic apocalyptic cult controlling atomic bombs. When the wide-eyed believer gets hold of the reins of power and the weapons of mass death, then the entire world should start worrying, and that is what is happening in Iran.”

Unfortunately, our current leadership in Washington does not see this issue with anywhere near the clarity that Netanyahu does…indeed, Obama seems more upset by American nuclear weapons than by the prospect of nuclear weapons in the hands of the Iranian regime. The same is true of a substantial number of Americans, especially those who consider themselves to be political “progressives” and who work in the media and in academia.

Ralph Peters: One of the most consistently disheartening experiences an adult can have today is to listen to the endless attempts by our intellectuals and intelligence professionals to explain religious terrorism in clinical terms, assigning rational motives to men who have moved irrevocably beyond reason. We suffer under layers of intellectual asymmetries that hinder us from an intuititive recognition of our enemies.

Paul Reynaud–who became Prime Minister of France just two months before the German invasion of 1940–incisively explained what was at stake at that point in time, and why it was so much greater than what had been at stake in 1914: People think Hitler is like Kaiser Wilhelm. The old gentleman only wanted to take Alsace-Lorraine from us. But Hitler is Genghis Khan.

Obama and his acolytes seem to think we are dealing with Kaiser Wilhelm-like figures in Iran and North Korea. It is a shallow and dangerously naive way of looking at the world.

Why do people who are highly educated, and often fairly intelligent, so often fail at comprehending and predicting the behavior of thugs and fanatics?

Finding a Less Costly Alternative

I wrote last year about how I finally took the plunge and canceled my cable TV service.

The reason why I decided to let the television go dark was because advancing technology made paying for TV shows redundant. There are very few that I like anyway, and they are available for streaming free through a variety of websites. Add the fact that my charity work kept me extremely busy, so I would only have time to watch TV at some extremely odd hours, and you can see that online video-on-demand was the cost free way to go.

Things have loosened up a great deal since I shut down the charity self defense course in January. The course put such demands on me that going to an eight hour work day feels like an extended vacation, and I have a great deal more time on my hands. Even so, I still find that only a very few TV shows are at all interesting, and have no desire to start paying for cable service that I won’t watch anyway.

But that isn’t what I want to talk about. You see, now I’m thinking about canceling my phone service.

April 1st

One of these two stories is an April Fool.

General Electric develops talking light bulb.

British Schools will no longer require the teaching of certain historical subjects, such as the reign of Queen Victoria and the events of the Second World War, but will instead emphasize twittering, podcasting, and blogging.

The other, apparently, is not.

Can you guess which is which?
