  1. Re:How long? on Giant Squid Caught on Film · · Score: 1

    Have none of your heard of altitude sickness? This is a problem that affects mountain climbers when they climb at high altitude. There are 2 main effects that result: pulmonary and cerebral oedema. This is what happens when the fluid in your body starts to pool in places that the body is used to having a bit of space - namely around your lungs and brain respectively. This problem can easily be fatal when travelling from sea level to 5000m (if you go quickly), and would be much worse in space. So even with a body covered in vaseline and a face mask, you'll still die. (and I wont even begin to talk about the radiation and cold) Now to get back to the topic (very rare on /. I know) I'm not sure if a giant squid is going to have that problem because of it's body structure. It may not suffer from cerebral oedema because it doesn't have a hard skull encasing it's brain (and not much brain I guess either since it has a penis that large!). It may not suffer from pulmonary oedema because it doesn't rely on having a gas move in and out of it's body (i.e. no lungs).

  2. Re:Why they can't use faster rotor speed on Carter Copter Breaks Mu-1 Barrier · · Score: 1

    RTFA.

    They got to MU whilst travelling at 170kts and manually reducing the rotor speed to 107 rpm (a meaningless coincidence that those numbers look similar) - not mach 0.5. They achieved mach 0.5 at a much higher rotor speed.

    Either that, or the post is a troll.... ;-)

  4. Re:Mathematics Out of the Closet on Mathematicians Become Hollywood Consultants · · Score: 3, Informative

    You're right - that's how triangulation works in theory, but in practice its not uncommon to use 3 or even 4 points of reference. The reason is that the angle that you calculate from your reference point to the unknown point is never exactly correct, and you probably don't know exactly where the reference points are either: you'll have thier position with a certain degree of acuracy - eg. +/-100m.

    If you're doing this over any significant distance you may need to calculate in the difference between a 2D map coordinate and the 3D surface of the planet. If the reference points are at different altitudes, then it's even less acurate.

    So if you do as the previous writer said, and use 3 reference points, then you end up with a small triangle where their bearings cross. The target is then in that triangle (or close to it) and the size of the triangle tells you how much confidence to have in the results - a larger triangle means that your reference points and bearings are less acurate.

    Incidentally, triagulation can be used this way for navigation using line of site signals such as light houses or trig stations too.

    Wow. Maybe I spent too much time in the boy scouts. ;-)

    In the article it implies that the full images were available in the data (i.e. a thumbnail in the JPG) - rather than the "wrong copy" being sent.

    Huh? Anyone who has taken a statistics class, (anyone who passed, anyway), would know never to say the probability is "ZERO", but that it is smaller than an arbitrarily chosen confidence factor (such as 0.01, or 0.005).

  10. Re:Big deal on Microsoft Found Guilty of Misleading Advertising · · Score: 1

    If you're in the US, and the normal style of advertising is to use exaggerated or misleading claims to get your attention, then your attention can *only* be grabbed by other misleading or exaggerated claims (or naked bodies of course)- and it means that you'll assume that any ad is misleading and exaggerated - so the one from Microsoft is no big deal.

    However, if you're in a country with stricter advertising laws, and you're used to seeing reasonable claims in ads, then why wouldn't you believe that the claims from Microsoft are real? You'd have no good reason to doubt those claims - and Microsoft shouldn't be able to make them because they are misleading.

    But the point is here: Microsoft broke the law by advertising this way in the UK. I'm assuming that the law is clearly there, advertisers in the UK need to pay attention to that, and Microsoft did not.

    You're right - rotating mass is only more significant when accellerating, but next time you're heading up Alp de Huez pay real careful attention to your speed on that hilly, windy, bumpy road and you'll notice that you're almost never at a "constant speed" and it's certainly not flat!

    PhysicsScholar, What are you on?

    Toshiba is a $47B company with nearly 200,000 employees. What makes you think they don't have someone in there smarter than you?

    And why does "...every engineer..." need to know all that stuff? Haven't you ever noticed that a group of people with different sets of skills can do something as a team that they couldn't do as individuals? Something called communication I believe...

    Oh bugger it - I don't know why I'm bothering with this - you're just trolling for flames anyway.
