  1. No Harm, no foul :'( on Know How To Use a Slide Rule? · · Score: 1

    I used a slide rule in my Celestial Mechanics class. We were calculating some orbit to the moon (yes, orbit, since we were going to the altitude of the moon, not the actual moon... two-bodies, y'understand) but I digress. I got an A, but The Professor called me into his office.

    "You did the equations correctly, but your answer was not correct. You had 60.42 (or something) and the answer was 60.4235. Why is that?"
    "Well, I can only see about 4 digits on my slide rule." I produced my 12" Yellow Pickett.
    "You used a slide rule?" This was the guy who used a slide-rule and non-diimensional equations to tell the Apollo 11 Tiger Team where The Eagle had landed, as they forgot to account for the thrust of the docking spring, sheesh.

    He reached into his desk and produced the exact same slide rule. Needless to say we formed a camaraderie from then on.

    He has recently passed away, and will not be able to see the flights of fancy he inspired in my fictional writing. :'( It's not often that an orbit is the co-star of a plotline.

    May all your mechanics be celestial, Professor Harm.

    I'm going to push back on this one...

    The Greek root word that is translated as 'wormwood' is "apsinthos". Certainly the same root word as "absinthium" but I am neither an etymologist, a botanist or a heavy drinker of vodka OR vermouth (which is also a wormwood allusion)

    But this is very moot (a wormwood pun). Yer missing the bigger picture here. The bible referred to a meteorite that made waters toxic. We have now learned that the Peruvian meteorite stirred up arsenic. Ok, so we have a meteorite that falls and releases poison in both accounts. This is pretty good science for a 1900+ year old document. We (science) didn't even know what a meteorite really WAS until the 1500's.

    If you want to quibble about plant species and transliteration of Cyrillic, have at it. That's what Slashdot is for. But you might also want to ask how a ancient bible prophecy described very closely that news headline you just read, and why Revelation looks so much like astrophysics story problems set.

  3. Rename Tiger to R2-D2 on Apple's Leopard Will Exclude 800MHz G4 Processors · · Score: 1

    Several months ago, I posted the idea of setting an "R2 standard" where a computer can be connected to and useful from now until... Much like the R2 unit that both Obi-Wan and Luke used in their fighters.

    This is a perfect example... an 800MHz G4 on Tiger could be one of those "droids". I was quoted as saying recently that "If this G4 Titanium with Tiger is all the computer humanity ever got, we'd be doing alright."

    Specifically, Spotlight is such a boon to workflow, that it's worth the Panther to Tiger step. I'm not sure that Leopard is.

    I know that with ever progressing technology, we can do things we never dreamed. But is that really a good thing? Last night I watched a YouTube video on my G3-400. I saw what I wanted.

    It takes a Titan IV to accelerate something as massive as an SUV into "orbit between the earth and the moon". The delta-V is about 10Km/s, ball park, plus or minus, give or take. The delta-V of an asteroid would have to be half an order of magnitude more and what... 10 orders of magnitude more mass? Picture a Saturn V which is scaled up so that the Command Module is the size of the New Jersey.

  18. Mass Extermination, not Mass Extinction on Nukes Against Earth-Impacting Asteroids · · Score: 1

    There is another element of a "hypothetical known impending collision (HKIC)". The orbital mechanics will give a very precise time of impact, because, if it ain't then, it ain't gonna happen. While the Ground Zero is going to vary with chaotic factors, we will know this much: "It will hit on [this] side of the planet at this time." Chances are, it would hit the Pacific Ocean. But if the groundtrack wends into heavily populated area, let's say for example, USA, then those people know that they are on the bullseye and will feel the devastation of even a Barringer Crater sized event. That is simple rocket science... But...

    What is NOT simple is said locale's reaction to being on the target! WWDUBYAD? What would George Bush do? If (in this hypothetical case) the US Government knew for fact that metric oodles of its territory, including its breadbasket were going to be devastated by an asteroid, what would we do? What would China, India or Russia do?

    To quote Sam Kinison: "MOOOOVE!" What we would see would be a push to move into territory that was safer than where we would be sitting then. China might move into India or the Steppes of Russia. If it were to hit the Pacific, where would Los Angeles go? Arizona? Where can you bivouac 8 million people for an indefinite period? And who will be shipping in the food?

    One of the first effects of an HKIC is a directional diaspora. The blast wave of the asteroid would pale in comparison to the advancing ring of nuclear fire as one massive group clamors out of the target zone, and those already there fight for their very existence. The first HKIC will not trigger mass extinction before it triggers mass extermination.

    This, more than any other reason is why planetary defense should not be handled by any one of us, but by ALL of us. A United Federation of THIS Planet!

    Great analogy.

    Now, imagine that someone skied up beside you, turned your skis the way they wanted, stole your lift ticket, and finally broke your skis halfway down a black diamond run.

    Then imagine that on the way up the ski lift, you are informed that in order to prevent ski theft, you will have a slope protection agent. "You are trying to turn left. Cancel or Allow?" But when you get to the top of the lift, you learn that you have to replace your favorite skis with more expensive skis. Then you need to upgrade your boots to this special limited selection. And none of them will fit into the bindings on the skis.

    Now, you are realizing that the choice of an expensive-ish (not really) snowboard ready-to-ride, or a roll-your-own board shop will get you down the hill in one piece. Cancel or Allow?

  20. Re:Private sector space on Can Space Nerds Get Along? · · Score: 1

    Personally, while I agree that humanity should *eventually* have that sort of capability, I'm not sure it is worth pursuing at the present moment. I'd rather the money went towards basic propusion research, earth/space based telescope construction, and asteroid tracking programs than some sort of "Armageddon" boondoggle. That same logic may have been applied to other heavy lift vehicles, and that *eventually* we may have developed something similar to, if not better than the Saturn V. But I doubt that we *would* have were it not for Kennedy's boondoggle to the Moon in THAT decade.

    We are at the 99.94% mark on heavy lift thrust efficiencies. Hydrogen/oxygen has the highest "specific impulse" of any practical propellant. The SRMs produce more thrust (at a lower efficiency) than anything else practically available. We're not going to get much more efficient. We need to take that and scale it up. The Saturn V could put a "Volkwagen" on the moon in 4 days. The moon's orbit was pretty well known. (And according to my orbital mechanics professor who was at Mission Control at the time of the Apollo 11 landing, they missed the target by more than the width of an asteroid.)

    To get get something big enough to do anything to a smaller object which is moving in a "less well known" orbit will require MUCH MUCH more propellant than even the mighty Saturn V. (They didn't have to stop, they only had to circularize!) Are we going to wait until we only have 10 years to start developing it? (If we get a 10 year warning...)

    Go ahead... mod me "Asteroid Defence Fan-boi". But the laws of orbital mechanics are less forgiving than the Laws of Trickle Down Economics.

    • Build a launch vehicle capable of lifting "asteroid mitigation" equipment, whether it be Bruce Wyllis or a massive thruster.
    • Build a launch vehicle capable of lifting "astronaut rescue" equipment. Why? To rescue astronauts... maybe. But having a "get there quick" to the moon or even Mars will prepare us to rendezvous with an asteroid threat.
