    Two words: evaporative cooling.

    You can't go from body temperature to freezing within a minute just by sweating. Your body will close the pores on your skin and prevent the loss of sweat until your body is restored to operating temperature. You could lose some moisture through your mouth, but without any air to breath, you're not going to lose too much.

    I don't understand the grandparent's complaint about Battlestar Galactica because, if it's the episode I'm thinking of, the characters were only exposed to a vacuum for a few seconds.

    Which was considered "severe exposure". A few seconds exposure to vacuum is very far removed from "extreme exposure". Much less enough to cause them to freeze as they go flying out the side of the ship. In reality, the rescuers would have had a good chance of retrieving living (possibly quite healthy) people, even if they were exposed for as long as a minute.

    You seem to forget that:

    a) The body continues to generate heat that more than makes up for the black body radiation loses.

    b) Losses are significantly reduced by any insulating clothing worn. Even your standard shirt and pants provides fairly decent insulation. In the work suits worn on the Battlestar Galactica episode, the characters would have been more than protected.

    To actually lose more heat than you generate, you need to look to an active cooling solution rather than a passive one. Conduction (and by extension, convection) are the ones that cause the body to lose heat faster than it can produce it. Since there's no conduction in space, you're not going to lose heat faster than you can generate it.

    That's why I mentioned black body radiation in passing. It just doesn't matter to this discussion.

    Hollywood still does that. But with modern weapons being capable of holding an indeterminate size of clip (as opposed to the standard six-shooter), it's difficult to call them on it. They just throw a few clip ejections into the fray to make it seem like the characters are really reloading.

    You can kind of call them on double-barreled shotguns, but Hollywood has slowly phased those out for pump-action weapons. Of course, those are similarly amusing, but for different reasons. I was just watching an old episode of Sliders the other day where the characters are carrying pump-action shotguns. Every time they cut to a new scene, the characters would re-pump their shotguns.

    For example, Star Trek has something called a "Navigational Deflector". This is a device (sort of a reverse tractor beam) that sweeps ahead of the ship and removes small particles from its path before they cause a catastrophe. Similarly, shows that posit the existence of hyperspace deal with this from the perspective of hyperspace being a shortcut to another place in space-time. Taking this shortcut does not necessarily convey any great velocity. Travel through "normal" space is usually done at relative velocities that are not dangerous in a non-perfect vacuum.

    Since theres no air convection taking heat away from your body and any sweat would immediately vapourise as it came out your pores so it wouldn't have a chance to spread over your skin and cool you.

    When you sweat, the fluids come from inside your body. Since they're already heated, they will carry away some of the heat when they vaporize. So you'd probably die of other causes long before you overheated.

    In the Space Shuttle, however, the bay doors are opened for heat rejection when in flight. Unlike the "cold" problem we see in Star Trek whenever they lose power (e.g. TNG: Booby Trap), they're far more likely to overheat due to the heat rejection systems being inoperable. (Presumably, a ship like the Enterprise would have a circulatory system that would pump heat from the inside of the ship to the outer skin, where it would be rejected as black body radiation.)

    That one bugged me about a recent Battlestar Galactica, as well. Inside the room, the characters were freezing because the air was leaking away. (Thus cooling the room.) I can accept that. But once they're blasted into space? Not a chance of freezing. No air for cooling == no loss of heat. (Actually, you can still lose it slowly through black-body radiation, but that's another topic.) Human skin is pretty good at holding pressure, so the big things are:

    - Don't hold your breath (unnecessary internal pressure)
    - Close your eyes (they're more susceptable to decompression)

  10. 9 Bad Excuses for a Fluff Piece on 9 Laws of Physics That Don't Apply in Hollywood · · Score: 5, Interesting
    First, let me preface this by saying that Hollywood is fiction. I think when we see the tanker truck blow up, the Power Rangers jump-kicking someone in the chest, or Neo fly through the air like Superman, we understand it's fiction. It's called "suspension of disbelief." It's what makes movies enjoyable. No one is really going to think that these things happen as regularly (or at all) in real life as they do in the movies.

    That being said:

    Explosions on the battlefield go boom right away, no matter how far away spectators are. Even a small thing, like the crack of a baseball player's bat, is simultaneous with ball contact, unlike at a real game.

    In most instances that come to mind, the director takes care of this problem by zooming you in on the Volcano, shell explosion, or baseball hit. Once you hear the sound at the source, the director usually cuts away to the actors after the sound has arrived. (As can usually be surmised by the ash and dirt flying at the camera.)

    Hollywood always gets this one wrong. On film, thunder doesn't follow lightning (as in real life, because sound is slower); they occur simultaneously.

    To the human ear, they are effectively simultaneous if the lighting crack is close enough to the observer. Considering how LOUD the director usually chooses to make the thunder, I don't think it's that bad of a summation. How about we start worrying why the actors aren't taking shelter?

    And because radioactive things emit light only when they run into phosphor - like the coating on the inner surface of a TV tube - you don't really need to worry.

    This is actually incorrect. Radioactive "things" can emit light through two other methods:

    1. They grow physically hot enough to glow red-hot or white-hot.

    2. They heavily ionize the air around them, creating pretty streaks and rainbows.

    However, the green-glow often seen in movies and cartoons does usually require the presence of phospher.

    So, when you see a gal kick someone across the room, technically, the kicker (or holder of a gun) must fly across the room in the opposite direction - unless she has a back against the wall.

    Or... the kicker could be properly grounded. If the kicker is properly braced against the ground, it's not impossible to send an unbalanced opponent off his feet. The fact that you can pick an opponent up and toss him in a single motion demonstrates that. That's not to say that the exact situation of many fights isn't ridiculous (excuse me, rediculous), but the physics of the situation don't prevent a kicker from delivering a blow hard enough to knock someone off their feet. Perhaps even to the point of sending them flying. (Though it's unlikely that it would be to the point of many kung-fu movies on strings. There's only so much structural capacity in the human body. After that, you start breaking your own bones.)

    Now when they miss their target and don't go flying across the room... :-P

    But in the movies, buses and cars shouldn't be able to jump across gaps in bridges, even if they go heavy on the accelerator.

    Unless, of course, there is some sort of incline for a takeoff (ever notice how the Duke boys always manage to find that conveniently placed incline?) or the second section is lower than the first, thus allowing for the jump to complete depsite the drop in altitude. (As the camera appeared to make the situation in Speed.)

    The problem, though, is that their voices don't change. In reality, if you slow down motion by a factor of two, the frequency of all sounds should drop by an octave.

    Smash cuts don't exist in real-life, either. Yet we don't complain about those. Slow motion is an entirely artistic thing, and is not related to the physics of the situation. At all.

    So not only is your god mutable

    What's the point in being God if the rules don't follow your whim? :P

    Actually, the law is based on a single promise. The promise of eternal life to Adam and Eve. The problem was that Adam and Eve failed to follow the single law they were given (don't eat from the tree at the center of the garden) and were cast out. But that's not entirely fair to their descendents, so they each had the choice to live their life according to the promise given. The 10 Commandments were a set of laws God gave to the Jewish civilization so that they would know how to conduct themselves in a pure form. If one sinned, they were required to atone for that sin. The most common atonement was to slaughter a lamb as a sacrifice. This was symbolic of the fate that would await the savior. You see, in Judaism, they believed in Christ before he came. Those who continue to practice Judaism believe that he hasn't arrived yet.

    The harshest penalty (death) was reserved for only the highest crimes, murder being the most obvious. Even then, you'll note that God was merciful in many sitations, sparing the the life of the individual.

    at one point in time (approximately two thousand years ago) it punished people for myriad minutiae (I'm thinking of Leviticus here)

    You need to be more specific. Leviticus set up the laws under which the Jewish people lived. They did not differ all that significantly from the laws we live under today. The only thing that's changed is that today's laws are not as hard and fast as those of the old testament. e.g. When you sleep with a virgin woman outside of marriage, it may be "wrong" from a Christian perspective, but the law doesn't require you to marry her and pay the father 100 shekels of silver. Today's law in Christian societies recognizes grace, which the old testament did not. This follows a general societal pattern of placing greater value on life. If you look back in history to the period in which Leviticus was written, the humans of the world did not place a very high value on an individual's right to live.

    I'm curious why you think your omnipotent god changed its mind all of a sudden?

    He didn't "suddenly change his mind". First off, the savior was promised to the Jews long before he arrived. The primary purpose of the Bible is to track his lineage, going all the way back to Adam and Eve. It was important that Jesus be a son of man and not of the Niphilim. The Bible also tells us that Jesus spent time in the place of imprisioned spirits (hell? purgatory? I'll leave that to the scholars) preaching to them so that they might also be saved.

    You are mistakenly quoting the law. Under the law it was incredibly difficult to get to heaven. Under grace, it's as easy as:

    "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life." --John 3:16

But if, while we seek to be justified by Christ, we ourselves also are found sinners, is therefore Christ the minister of sin? God forbid. For if I build again the things which I destroyed, I make myself a transgressor. For I through the law am dead to the law, that I might live unto God. I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.

A storyline can do a great deal to improve a game, but it can also detract from it. Most of the "great" games of times gone by never had anything more than a token plot.

    Q: I wonder if you can think a little further out. Give us your vision for the gaming experience say, five or 10 years from now.

Five years, in terms of what are the products going to look like, imagine Nemo-like graphics with much more realistic characters and animation. What I think is going to be important to the future of this business, in addition to better graphics and better sound and smoother animation, is that we have to be better storytellers and that we start to create characters that people care about. I think that, longer term, (it will) help to broaden the demographics where we get more women into the demographic and even broaden the age demographic.

    No wonder they've got a bad reputation! They've bought into the idea that better graphics == better games! Which is exactly what is visible in the Superman Game. It seems that no one really stepped back and thought, "what is it that would make this game fun?" They apparently thought they already knew the answer: Better graphics & a story from a movie tie-in.
