    On the other hand, movie technology is advancing rapidly. Take a look at the short film duality . (divx version available from divx.com).


    That movie was made mostly by two guys. Total crew for everything was around 8. They used good consumer level equipment. Editing and special effects were done on Macs using about $2000 worth of software. It's only their second attempt at a movie, too.


    And guess what? Duality looks as good as anything in the original Star Wars.


    I think we are entering a phase where the resources required to make a top notch movie with full special effects are going to go way down. So maybe it is true that it won't be possible to get a $200 million budget for a major movie...but I don't think anyone will need a $200 million budget anymore.

  8. That's Not Taiwan Law on (Almost) Free Movies On-Line... Sorta · · Score: 2
    I have serious doubts about this. Taiwan follows the Berne Convention on copyright. One of the the requirements of Berne is that you cannot require formalities such as registration.

    You are allowed to apply different rules to your own citizens and their works. For example, the United States does have registration requirements that must be met if you want to sue for certain kinds of damages. If a US author doesn't register, their remedies are limited. If a foreign author doesn't register, they aren't limited. Yup...US law actually treats foreign authors better than US authors (and if you are going to pirate...pirate domestically!).

    What's probably happening, assuming that there is a grain of truth to this story, is that Taiwan is doing what the US does, and subjecting their own people to extra requirements. So, it is believable that a movie made in Taiwan that is shown and not registered does not get copyright, but it is certainly not true for foreign (to Taiwan) movies.

  10. Measuring the speed of light with a ruler on Speed of Light Measurement Using Ping · · Score: 4, Interesting
    One day in APh 23 (the introductory optics class) at Caltech, the professor announced it was time to measure the speed of light, and pulled a ruler out of his pocket. The class laughed.


    He then turned on a laser of known wavelength, and reflected the beam off the ruler onto the chalkboard. The ruler had raised lines every 1/16th of an inch, and this made it basically act as a diffraction grating, and there was a clear diffraction pattern on the chalkboard. He marked off the pattern on the chalkboard with chalk, then took the ruler and measured the distance between the lines on the diffraction pattern. Then, still using the ruler, he measured the distance to where he had held the ruler.


    A quick calculation later, and he had the speed of light.


    I'm not sure that this was fully legitimate, because I can't think of a way to know the wavelength of the laser that doesn't involve already knowing the speed of light, but it was interesting nonetheless.


    Speaking of interesting things to do with interference patterns, that professor did some work at Hughes on an optical weapon system. It had an array of radiators. Turn them all on, and you get a classic interference pattern, so you get a strong lobe in one direction, and not enough radiation in other directions to harm anything. The cool part was how it was aimed.


    You aimed the main lobe by playing with the phase of the various radiators, so you didn't have to move things around to do fine aiming.


    Here's the cool part. They used a feedback system. The modulated the phase of each radiator with a sine wave, using a different frequency for each radiator. They'd point a sensor at the target, and look for variations in the intensity of the reflection. If a particular radiator was at a phase that was contributing toward putting the max lobe on the target, there would be a weak variation in the reflection at the frequency of the sine wave they were modulating that radiator with (if the radiator is at the right phase, you are near a peak, and small variations from the modulation don't lose much). If a particular radiator's phase was way off, you'd get a strong single at the frequency of the modulation.


    So, they could simply do a fourier analysis of the reflection, and see what radiators needed their phase adjusted to hit the target.


    The professor had a film of a test, with a small number of radiators. They were all pointing at a black background, and you saw a kind of vague shifting light pattern. Then someone tossed a small metal model of the starship Enterprise in, and blam!, the phases were adjusted in a millisecond or so, and that thing lit up. It was very cool.

  16. Re:Free Energy not impossible on News Media Scammed by 'Free Energy' Hoax · · Score: 2
    Perhaps these laws of thermodynamics are only valid within a particular context, and the free energy comes from outside that context?

    The context in which conservation of energy is valid is a universe in which the laws of physics are symetrical with respect to time. (Conservation of momentum is a consequence of symetry under translation, and conservation of angular momentum comes from rotational symetry).

    Since there has never been even a hint that these symetries don't hold in our universe, anything that claims to violate conservation of energy (or momentum, or angular momentum) is extremely unlikely.

    All correct, of course, and nicely demonstrating my point that "you can't get out because you can't go faster than light" has little to do with it. Basically, the escape velocity being greater or equal to lightspeed is a consequence of why you can't get out, not a cause.

    Thought experiment for you: take an object and start moving it upwards at 10 miles/hour (it can be a rocket with a large fuel supply, or you can supply energy from the ground, e.g., with a launching laser). Keep supplying enough force to keep the object moving away from earth at 10 miles/hour.

    Question: what happens to this object?

    Answer: it gets arbitrarily far away from earth. After a year, for example, it is about as far away as the moon.

  21. Re:no singularity... on Black Holes Disputed · · Score: 5, Insightful
    Yeah, that's the physics geek explanation. When I posed this question to one of my physics professors at Caltech back in my student days, he came up with nothing better than that, either. Basically, as far as we could tell, (1) the "escape velocity is greater than speed of light, and nothing can go faster than light" explanation has nothing really to do with it, and (2) there is no simple intuitive explanation of why you can't get out of a black hole (where "simple intuitive" means comparable to the escape velocity explanation).

    This reminds me of the explanations in books for the general public on how airplanes work. The usual explanation is that because of the curve on top of the wing, when the airflow splits at the leading edge, the part that goes over the top has to go farther to meet up with the corresponding part that goes under the wing, and since it has to go farther in the same time, it has to go faster. We know from Bernoulli that a faster airflow has lower pressure, so we get a pressure differential, and the wing rises.

    Anyone see the problem with that? The first problem is that no reason is given for the airstream over the top to have to meet up with the airstreem under the bottom. Why can't it just flow straight back?

    The real reason wings work is that they cause vortices to be generated that, because of the shape of the wing, go down, and since vortices have momentum, by the usual laws of elementary physics, there is force upward on the wing.

    There is no simple explanation of why wings cause these vortices, but no one likes to say in their books for laymen that it takes a PhD in aerodynamics to understand how airplanes work, so we get the totally irrelevant Bernoulli explanation.

    It would be interesting to compile a list of various areas in science and engineering where there are explanations for the general public like this, that are basically wrong, and are so widespread that even scientists and engineers use them without thinking about them when writing for the general public.

    You missed the point. A rocket can leave earth, for example, without ever reaching earth's escape velocity, because it has thrust, whereas a bullet would need to be fired at escape velocity or higher to leave earth. Heck, you could leave earth without ever going faster than 1 mile/hour, as long as you had enough fuel.

    Try again.

    I've never understood this. Escape velocity is the velocity you need to get out frem a given point in a gravity well with no thrust. Can anyone give a good intuitive explanation of why a rocket could not get out of a black hole?
