An object moving in a circle must have a force exerted on it to follow F = mv^2/r If that force is the weight, i.e. v^2/r = g, then the bucket cannot be exerting and force. But what happens if the bucket is swung faster? Or slower?

In parts III and IV he seems to be saying that you can represent time as the phase of a pendulum and restate other variables in terms of that. But this does not forget time, it merely renames it. Time is the phase of an oscillation. I'm not sure his objection "How do we know that a clock measures time, if we can only check it against another clock?" means anything. Isn't the same thing true of mass? Can you measure mass without using forces? A clock measures time because that's how we define it.

I split this off from the GW thread. That seems to be the only story on the topic at the moment, and it's sparse on detail. edit: more articles. Very little, if any, more information. Some is even conflicting http://www.off-grid.net/2008/10/31/micro-nuclear-plants-for-local-power/ http://gigantico.squarespace.com/336554365346/2008/11/9/nuclear-reactor-home-edition.html One article says 200 kW, another says 25 MW. 10,000 homes one place, 20,000 homes another. But those numbers indicate 25MW is probably correct. The typical home uses 1 kW on average (i.e. somewhere, roughly, around 24 kWh per day), but this varies throughout the day. This raises the question of whether the system can keep up with peak demand.

Other than ParanoiA's rather extreme view on this, nobody else seems to have addressed the idea that there is educational value in community service, which is likely why it is put in terms of student participation rather than being age-specific. You may not like having to read Shakespeare in class, either, but education isn't about what students want. Public service, I would argue, has educational value, and that appears to be the context in which the plan is being offered. This is no more oppressive than mandating that everyone complete four years of English classes, or algebra or whatever your least favorite subject is/was in school. Not all will appreciate it, but some may value the sense of accomplishment of having helped someone or improved one's community and/or country.

Not so much. The number of people voting democrat has steadily increased since 1980. http://www.mexicanpictures.com/headingeast/2008/11/a-little-historical-perspectiv.html

You've described a circle, not a sphere.

Oooh, I guess mandated education is unconstitutional too. Child labor, too, even. How despicable.

How much fun is there in forced military service?

traveler has been banned for persistent rules violations. Trolling, thread hijacking and circumventing a locked thread by bringing up the material in the hijacked thread.

Several posts have been moved from another thread, which is why posts appear after Sayo closed it. Hijacking is against the rules. Hijacking to circumvent a closed thread is doubly so. And this was hijacking that was also trolling, on a closed topic. A triple whammy, and if anyone wanted an example of how not to behave, here it is.

Less partying, more studying math. (Try doing the calculation again)

Both the age and citizenship requirements are in the Constitution. The question here is does anyone check, and how do they do so? Do they card you when you announce?

Gah. I misread something in your post (I somehow read the "and" as an "or." Boolean fail) If Apple were actually restricting apps in the app store then that would be anticompetitive. I just don't think that's the actual case, because it apparently isn't part of the developer agreement, and there are lots of developer apps that duplicate existing app functions, and other podcaster and I think one other, these haven't been pulled. But Apple does (or did) have some a general "we can pull any app for any reason" caveat, which could be a killer for developer enthusiasm if it's seen as being applied this way.

What paperwork do you have to file to be put on a ballot? Does that include proof of meeting the credentials? One doesn't need to focus solely on citizenship — what would happen if a 32 year-old tried to run for president?

No, I don't think you are right. Microsoft could have, at the outset, made a completely closed system: sold their OS on their own hardware, and all the software for it. (Had they done that, though, they would never be in the monopoly position they are today.) But they didn't, so it's not an apt comparison. When the iPhone came out, exactly zero developer software was allowed on it. Was that anticompetitive? Can I sue the original makers of Pong? They did the same thing. Don't makers of gaming consoles make you do basically the same thing — license the right to make a game for their console? That's really all the app store does — enforce the licensing agreement of who gets to write software. It wasn't a comparison, it was an aside.

Once the sweat doesn't evaporate it doesn't do you much good, but your body doesn't really "know" this, so you sweat and sweat. It's the body's reaction to being too hot. My very first blog post was about this http://blogs.scienceforums.net/swansont/archives/1

But this is no different than turning on a heater to warm the house up — if one area is better coupled to the outside, you will still transfer that energy. It's also true that water will tend to condense on surfaces that have a large heat capacity. It's not just the coldest points. Some people find low humidity to be very annoying. It dries out the skin. But it all ends up flowing to the cold region, and trying to get to equilibrium. Cold things radiate, too. They just don't radiate as much.

The phone has been strangely silent the past few days. I do expect the Dems' customary "Have you voted yet? We'll drive you to the polling place" call in an hour or two.

I can't reconcile those two statements. If the acceleration is different, the force cannot be the same.

I have no idea. I have no familiarity with this kind of detail. But if he's self-employed, he needs to charge at least $125 an hour for this to be an issue (assuming 2000 hours worked) Plumbers seem to fall a little short of that.

Windows is an OS (and a monopoly at that) put on computers that Microsoft does not sell, and computers are for running programs. That's not even close to the same thing. But, can you buy these competing apps at the Microsoft website? BTW, Microsoft is reportedly going to open their own version of the app store for Windows mobile, called Skymarket. I predict it will not do as well, because Microsoft does not control the hardware that their OS runs on, which makes it harder to do the software.

No. Relativity and our laws of physics are applied to inertial frames from things that have mass. These cannot move at c.

Getting back to the topic of Joe, it occurs to me that this is a huge red herring. I know a few people who have run their own businesses. They incorporate them, so the money earned by the company is separate from what they earn (and, I assume, shields them from personal liability). What you need is a decent accountant. One of these guys was explaining this to me recently. The goal for his personal income was to make very little money, and leverage the business and corporate tax laws as much as possible. Instead of having an income and then paying for things, you can have the company provide you with benefits, some of which are not taxable at all, and some of which have a lower tax burden. Business taxes are capped at 35%, and with various accounting tricks, the actual tax rate is often lower. That's where the big income is. Not with the individual. So if Joe actually were average and were planning on buying the business, he probably still wouldn't run afoul of the $250k threshold for the higher taxes.

Energy is conserved. If the hot water evaporates and then condenses all you've done is move the energy around from the hot area to the cool area, just what you'd expect from the 2nd law of thermodynamics. If, as the context suggests, we're discussing winter, then chances are the air is drier than normal, because cold air has been heated up in your home, and cold air can't support as much water vapor. So you might be doing yourself some good as far as humidifying the house. The alternative of letting the water condense inside the dishwasher and drain means you are letting hotter-than-ambient water move out of your house, which does waste energy.
