  2. Re:Missing parts... on Harvard Professor Creates Paper Accelerometer · · Score: 1

    It's nice to pick and choose bits of previous posts to make it sound like that's what you meant, but I know that what you meant is that "oscillating means AC" and that just doesn't jive with the dictionary definition of the term. But congratulations, you won a pointless battle with somebody who wasn't trying to fight in the first place and who you'll never meet :-)

  3. Re:Missing parts... on Harvard Professor Creates Paper Accelerometer · · Score: 2

    The terms AC and DC have two subtly different meanings. In one of them, AC is distinguished from DC because AC oscillates and DC does not. In the other sense, AC differs from DC by virtue of the direction of current flow -- the current only "alternates" if it actually comes to a stop and flows in the opposite direction. It's possible to have oscillation without the current changing direction, for instance a 1 MHz oscillation that ranges from 0 volt to 1 volt. The current always moves in one direction, though its amplitude varies.

    So yes, indicating AC is not redundant. It means the voltage passes through 0.

    If a dimwitted student is holding back the rest of the class, I want the teachers empowered to say so and do something about it.

    There are ways to do that that don't involve ridiculing the "dimwitted" students. This isn't about protecting the self-images of precious little snowflakes, it's about basic human decency and the fact that it's fucking rude to talk about people that way, children or otherwise, especially in a public forum.

    It's not the idea she communicated that got her fired, it's the unprofessional manner in which she did so. What happened here isn't "bad speech, you get fired," it's "unprofessional behavior is not tolerated."

    If the only force you experienced was an upward force, you'd accelerate upward. You do not, because the upward force of the chair is the same magnitude as the downward force of gravity.

    In terms of general relativity, the force of gravity isn't really a force, and the only true force on you is that of the chair, which serves to keep your body moving along a geodesic of spacetime, but seriously, general relativity is unnecessary to explain the operation of an iPhone accelerometer.

    Really? I was under the impression that gravity was accelerating me towards the center of the earth. At least, when I jump, I seem to come back down again. Maybe I'm standing upside down.

    No, he's right. The force of gravity is indistinguishable from what you'd feel if you were in an elevator accelerating upwards at 1 g. Come on, this goes back almost 100 years to Einstein's thought experiment which led to the general theory of relativity.

    When you're standing on solid ground, what do you feel? A force pushing UPWARDS on the soles of your feet. The sensation you have of gravity is that of a force pushing your body UPWARDS. Think carefully about it. Sit in a chair. What parts of your body experience force, and in what direction? Do you feel a downward pressing on your shoulders, or an upward pressing on the backs of your legs and your butt?

    This is a matter of perception. The force is actually a downward force. But in all respects, the effects due to that force are the same as if you were in an accelerating reference frame with the acceleration directed upwards.

    AI is always in the future, almost by definition. As soon as any new "artificial intelligence" algorithm goes mainstream, and starts to be incorporated into real products, people tend to stop thinking of it as AI and more of "just what those computer thingies do." So it's you who keeps changing the definition of what AI is, it's not a lack of forward progress.

    AI tends to be "whatever the most advanced stuff is that people are working on." I hate the terminology, as do you apparently, but a problem with terminology doesn't mean we're not inventing anything.

  16. Re:Dumping snow in the river on 1948 Mayor To MIT: Use Flamethrowers To Melt Snow? · · Score: 1

    Assuming a density of 80 grams per liter (about 8% that of water), a cubic meter of snow has a mass of 80 kg. Heat of fusion of water ice is 333.55 kJ/kg, so it would take a minimum of 27 MJ to melt one cubic meter of snow (more, if it is substantially below freezing). Assuming a 10 hectare campus, and a depth of 1 meter, that's 100,000 cubic meters of snow requiring 2,700,000 MJ of energy to melt, which is 2.7 TJ which is about the amount of energy produced by a 1 gigawatt power plant in a time of 45 minutes...

    I have no doubt that Bear Grylls has some pretty mad skills. What I don't like is how he presents certain things as if they were actually valid survival techniques for the average person, instead of admitting that he's just trying to be impressive. Sometimes it's stemming up a ridiculous chimney climb in tennis shoes, sometimes it's constructing a rope swing from a flimsy vine and then swinging across a 200 foot chasm, or climbing a rickety tree to take a look at the terrain ("It's hilly"), or tackling a wild board and killing it with a knife... All of which are probably decent survival techniques for Bear Grylls, but for most other people doing any of these things is a GUARANTEED way to get killed.

    Sure, at the beginning of the show they throw up that disclaimer, but the guy's ATTITUDE during the show is more like "Watch me and learn these techniques, so you can save yourself if you're ever lost in a desert/deep forest/ice plateau." It's suicidal to try to do most of the things this guy is doing.
