  1. Re:Disaster magnitude? - why it's bigger on Space Shuttle Columbia Breaks Up Over Texas · · Score: 1

    This might be a little callous, but I think it's at least part of why this is such a bigger disaster - there's a lot more planes, trains and cars moving around every day, and they're not nearly so engineered as a Shuttle...and they still actually have a lower accident rate than the Shuttle, which is 2 for 107. I'd personally expect a lot better performance from something that's that overbuilt; it's like a fully loaded, completely redundant IBM/SUN/SGI/&c. server spontanously failing 1 in 50 instances.

    i am a scientist, and neither of these tests has any sort of scientificism about them. you got the second one ok, but the first one used a poor choice of software (should have been the leanest, most optimized package for each system), a very limited set of test processes, and incredibly disparate hardware - yes, it was supposed to be 'top of the line' systems, but it's really bananas to cherries here; it's like dragging an extremely elegant, sophisticated, state-of-the-art 800hp F1 car up against an old-school brute-force 8000hp Top Fuel dragster and declaring the dragster a much better overall car, because it can romp in the 1/4. by that reasoning, i could say that this rock repels tigers...

    They purposefully take many more crew members than they need so that when they lose half of them in battle the ship can still function.

    A lot of people have been pointing this out, but it seems to me to be largely irrelevant in this day and age - any kind of combat an armed surface ship is going to encounter is going to either do so little actual physical damage as to be irrelevant, or it's going to straight-up sink it (look at the Sheffield, the oversize crew was just that many more people to die). Basically, here just don't seem to be that many weapons systems left these days that have the capability to do severe damage to a ship, killing half the crew, and leave her in any shape that the surviving half is going to want to try and stay aboard - it's either a skiff full of C4 attacking you in harbor, or an Exocet missile blowing you clean in half, there's no middle ground anymore.

    A balistic weapon traveling at 4,600 MPH can't change direction much in 300M

    No, a ballistic weapon can't change direction at all once it's fired. That's what separates a ballistic weapon (bullet, shell, dumb bomb) from a 'smart' weapon (guided missile, smart bomb); the guided weapons are just that, while a ballistic weapon relies soley on it's own momentum from firing and gravity to put it on target (remember projectile motion from Phys101?). 'ballistic missiles' aren't technically truly ballistic, with final-stage guidance on the MIRVs, but the launch to suborbit is.

I looked forward, down the road shimmering slightly in the heat, the red light swinging lazily in the breeze, the lane lines coming together at some infintely far off point just below the snowcapped mountain on the horizon. Glancing down at the small LCD mounted below my stero, blinking and flashing like some outrageous Christmas ornament, showing me the pulse of my own car, I thought to myself, 'this one should be easy'. Seeing everything normal, I looked back out at the other guy and gave him a histrionic 'let's go, buddy!' thumbs-up, complete with foolish grin, and lightly bounced my foot on my own gas pedal, idly revving my engine up to a screaming seventy-five hundred revs right as the light turned green. His monstrous chariot, the epitome of the American Muscle Car, with no higher calling in life than to simply go as fast as possible in a straight line, came to life, howling like a Top Fuel dragster and spinning the huge rear tires like pinwheels, totally obscuring my view of the road ahead as his car leapt out ahead of mine. I laughed quietly to myself as I slipped the transmission out of first and into neutral and slowly rolled to a stop, looking up just in time to see the blue and white sparkle of the state trooper's lights as he skidded to a halt in the middle of the road, blocking the Viper and insuring a hefty ticket for that shadowy figure who dared to look at me and blip his throttle.

    so if less turbulent mixing in the combustion chamber produces a more even flame front that moves faster, why does it tend to increase detonation around the periphery of the cylinder? a really turbulent, inhomogenous vapor flow in the chamber does make for a rougher overall burn, but i know it tends to reduce detonation, at least significantly away from the flame front; detonation on the front isn't nearly so bad since those kernels are rapidly surrounded by the burn proper. i have yet to figure this out; maybe you can help with your infinite wisdom.
