    Poppycock. The cases were a magnesium alloy. The only way the guy got it to burn was to heat it to several thousand degrees so that the alloy broke down. Not to mention that he had to try it with two different cases, AND use tons of lighter fluid to get one to ignite. :-)

    The NeXTStep (a.k.a. OpenStep) API was developed as part of the NeXTOS that ran on NeXT workstations during the 90's. Several deals were made with other Unix vendors (including Sun) for them to support the "OpenStep" standard.

    NeXT was bought off by Apple, and was developed into Mac OS X. The OS X Cocoa API is really nothing more than the NeXTStep API set, and is almost 100% source compatible with programs from the old NeXT machines.

    The GPL is a license. not a contract.

    A license is a type of contract. From here:

    License - A contractual arrangement whereby one person (Licensor) licenses another person (Licensee) some or all trade secret, patent, copyright, trade-mark or intellectual property rights the Licensor has in or to an invention. Unlike an assignment, a license does not transfer ownership. A sub-license occurs when the Licensee has rights to further license the Licensee's rights to a third party. A license may be for a set term or perpetual, be non-exclusive or exclusive, and is often granted in exchange for royalties or other compensation.

    So, he may be in breach of copyright, but not contract.

    That depends upon his defense. He can either state that he agreed to the license (breach of contract) or he can state that he didn't (copyright infringement). Either way, redistributing CherryOS before the situation is resolved will get you into deep trouble.

    That is great an all for someone to see on TV, but does someone suddenly understand genetics when this concept is taught? I do not think so. I believe understanding comes from being able to use probability to calculate measurable predictions from this concept.

    Again, we're just talking about an introduction to the topic. For most people it is sufficient to state that we know ways of converting matter to energy, and methods by which we can accomplish the feat today. (antimatter anihilation, fission, fusion, etc.) Statements like "Energy is not an entity unto itself, but requires a carrier particle. Nature sometimes gets around this issue by using a massless particle called a photon." helps undo some of the nonsense drilled into them by Science Fiction. (Pure energy beings? Right.)

    If the person is sufficiently interested in the topic, they can follow up on it. I'd even suggest having a website that would collect reference material (Wikipedia links would be cheap and easy, for example) for someone to follow up on a show they saw.

    I thought that that the slugs were propelled by a chemical explosion.

    Well, that's true in the sense that a bullet is propelled by a controlled chemical explosion. However, I think you'd be hard pressed to find someone who would equate the detonation of a gun cartrige with a directed blast like the one used in an implosion device. Basically, a gun device wouldn't produce the large explosion like the Mark IV you mentioned, whereas an implosion trigger would. (In fact the gun device was retired simply because it was too easy for the guns to go off accidentally.)

    Either way, the result is the same. The fissable material is temporarily made super-dense, and in that time it managed to go critical, then super-critical.

    You're just agreeing with what I said. It was the conventional part of the bomb that exploded. There was no atomic explosion, what-so-ever.

    As for the Uranium contamination, I wouldn't worry about it much. U235 is a lightly radioactive, alpha emitter. It really wouldn't cause much harm to anyone unless they managed to collect enough of the stuff to cause a high degree of spontaneous nuclear fission. (read: a do-it-yourself atomic pile)

    All nuclear bombs use a chemical detonator.

    That's not true. There are two types of atom bombs. The first one is a "gun" type of device that produces super-criticality by firing uranium slugs at each other. The combined force of the collision is sufficient to produce a super-critical reaction and thus an explosion.

    The second type is the "implosion" device we all know and love. This variation uses a standard chemical explosive to produce super-criticality in Plutonium-239. This device is actually a bit more scalable (i.e. powerful) than the gun device. As a result, implosion devices are used as the trigger for fusion (i.e. thermonuclear) bombs.

    In a thermonuclear bomb, the atmoic blast is reflected back on deuterium via the use of a Uranium neutron reflector. Since all the force is contained, the device heats up to temperatures similar to those in the sun, and the deuterium is forced to undergo fusion.

    The concepts can only be parodied in a 45 minute program. Without the theoretical background, based in Math, the science is only an approximation.

    So that's what we do when we brainstorm on new engine designs, or work out how to make Nuclear Fusion work. We simply "approximate" by saying "I want Nuclear Fusion", then we write a formula. Right.

    Or maybe we figure out how an engine or fusion might work, then run the numbers to see if it will work. Don't believe me? Here's an equation for you:

    k = f - l

    What does that mean? Does it unlock the secrets of the universe for you? No! Of course not! It's just an equation to describe the total amount of fission by neutron capture. It doesn't explain that fission is accomplished by making the atom too heavy instead of blasting it apart with energetic collisions. Someone smart had to figure that part out!

    Same thing with e=mc2, or Isp=EvG. These formulas merely descibe the physical properties of the universe in a form that allows us to know exactly how things will behave. Many times they are approximations themselves.

    Besides, if someone gets interested enough in a scientific subject from watching a Science show, then they can spend the time with a book or on the Internet to look up the formulas.
