Comment Re:Gallons per mile? (Score 1) 403

This is why we use MPG and why they put big numbers on the speedometer even though that 4 Cylinder would never make it to 120 MPH.

Considering how long Indy racers ran with four-bangers ...

Or for that matter, my Subaru with its four-cylinder Boxer is basically an updated version of the car that holds a long list of speed records for distances like 50,000 km -- at sustained average speeds of over 135 mph.

The real reason auto manufacturers put silly speedo ranges on is to keep the most common highway speeds in the upper quadrant of the dial, for quick reading and thus faster times getting your eyes back on the road. And, yes, I've worked with the auto industry on speedometers, albeit long long ago.

The reason it's considered inferior is because it's inverted from what you really care about - what you care about is "how much fuel will it take me to get n miles".

No, what I really care about is, "can I make it to the next fuel stop with what I have in the tank." Which is not a problem in most of Europe, but is very much a problem in large parts of the USA.

And unlike the manufacturers' economy claims, I use the number on a regular basis instead of just when I'm planning to buy a car.

Comment Wavefunction collapse (Score 2) 770

This whole discussion is distorted by the framing around "belief." As long as the result of a scientific inquiry is "belief" it's reasonable (in the "sound reason" sense) to hold the issue open and speculate that Einstein's General Theory (or the current version of Darwin's) might in fact be totally wrong.

But that's where the denialists play word games. They talk about open minds, and how consensus isn't dispositive, etc. and then use that as an argument against teaching evolution in schools or taking steps agains AGW. Or, for that matter, against teaching heliocentrism or plate tectonics.

The "scientific consensus" may not be dispositive in any epistemological sense, but when it comes time to collapse the waveform and make a decision it's certainly the way to bet.

Comment The human touch (Score 3, Interesting) 102

Thanks to a prosthetic knee, I get the "human touch" every time I fly. That's after a trip through the pornscanner and taking out all of my electronics and startingt them up, of course.

As for the kiosks -- if you know what you're doing, the last thing that you need is the kind of condescending "help" that gets in the way of getting your freaking boarding pass.

Comment Gross or net? (Score 2) 155

The United States exported about $106 billion worth of such goods last year.

It's one thing to export $106 billion more than you import and quite another to export $106 billion while importing $250 billion.

A good rule of thumb is that if an article doesn't explicitly tell you that it's a net export, it's because it's a puff piece with a bias and the truth would harsh the whole slant.

Comment Chicken or egg? (Score 3, Interesting) 230

Yes, lots of educated (and wealthy) citizens create markets for better services in cities. But decades of surveys of companies planning locations and of educated workers considering relocation tell us it works the other way around, too.

States like Arizona and Texas that base their plans for attracting high-wage (lots of educated employees) employers on cutting taxes usually do it by also slicing schools and other services.

That seems to be working in places like Austin, where the city makes up for the lack of State support for education (or actual hostility to it) by cranking up local sales taxes -- which fall more on the poor than on the affluent. Which is a sweet deal if you're making serious money as a twenty-something in technology there, but might not look so good when you have kids and you're looking for daycare and primary schools.

We're doing the experiment. Check in again in ten or twenty years to see which way the arrow of cauality runs.

Comment Re:But you can still (Score 1) 702

Ask yourself: what does the TSA do to detect iron oxide and aluminum? (Much less magnesium! MacBooks, anyone?)

They've known about this for years. They have quite competent "red team" people who think up possible threats, and they're not remotely so stupid as to believe that the Bad Guys can't think up this kind of thing themselves. Ask a classroom of sophomore-level engineering students to come up with ways to get plane-killers aboard and this is one of the first ones -- although it's a very, very long list.

However, stopping thermite from getting onboard is going to be way more of a public inconvenience than their mission statement allows.
