  1. Re:Here and now? on Robert Zubrin's Mars Gashopper Airplane · · Score: 1

    Problem is, kilograms are properly a unit of mass, not weight (or force). Mars has about 3/8 the surface gravity of Earth (I think), so something that weighs (exerts a downward force of) 88 lbs on Earth weighs about 33 lbs on Mars. But it will still have a mass of about 40 kg.

  2. Re:Here and now? on Robert Zubrin's Mars Gashopper Airplane · · Score: 1

    Interesting question. From the article: The simplest gashopper could actually be quite light, as little as 50 kg (110 pounds). That's using Earth gravity conversions. The same 50 kg would weigh about 41 lbs on Mars.

    But this little beast will use most of its propellant on forward motion, and acceleration relates to mass, not weight. Density of atmosphere will be the other factor, affecting the amount of lift the wings generate.

  6. Re:Those rat b--- on Color Laser Printers Tracking Everything You Print · · Score: 2, Informative

    Nobody prints with green ink.

    Nobody at home, maybe. Commercial printers print with all kinds of ink. If a pamphlet, coupon, or package only needs a few colors in block graphics (no complex shadings), it's more practical to use exactly the colors of ink needed than to uce CYM. Color alignment is simpler, and you use less ink.

    Q&D example off my shelves: Dove soap. The package is has only four colors, two for text, one for solid graphics, and one shaded. The printer used four colors: black, deep bluish-green, light bluish-green, and gold.

    The hardback editions of The Neverending Story were also printed with a bluish-green ink.

    Or think of green-lined ledger pages; you think a printer is going to go to the trouble to line up a cyan and a yellow run when he can do one green run and be done with it?

    So it's entirely plausible that an ink manufacturer or a commercial printer had to abandon a particular variety of green ink as being too close to one of the government's protected shades.

  11. Re:People think in their languages. on The State of Natural Language Programming · · Score: 1

    While it's perfectly possible to parse natural language, it's an impossible problem to reliably extract meaning from it. This is because most meaning in a natural language sentence is not encoded -- it is infered by the hearer based on assumptions about the attitudes, knowledge and intentions of the speaker.

    That's a good deal of what I meant by, "Thought patterns are learned and largely cultural," and "The system would have to be tailored to each. . .culture it would serve."

  13. Re:People think in their languages. on The State of Natural Language Programming · · Score: 1

    Good Lord, that's the truth. Most people I know have no idea how restrictive English grammar is, and how much variation there can be with other languages. English speakers (at least the grammatical ones) are familiar with a handful of verb inflections -- singular vs. plural; present or past tense -- but Old English actually inflected the nouns of a sentence as well, to indicate the subject and the predicate. You could say either "Dick hit Jane" or "Jane hit Dick" and the noun inflection, not the word order, determined who actually got hit. I'm no linguist, but I believe there are contemporary languages with similar features.

    That's a vast conceptual shift, that a person's name can be said differently according to whether he's the subject or the object of an action. How would "natural programming" be different to a person for whom word order is not significant, but individual word structure is? That's a complete shift from classic programming languages (although methods and attributes could be thought of as "noun inflection" in languages like Java or VB, you still can't just put your variable names anywhere you want in a statement).

    There are no natural ways of thinking; thought patterns are learned and largely cultural. For "natural programming" to really work, the system would have to be tailored to each native language and culture it would serve. At least with FORTRAN you didn't have to worry that a programmer from Sweden and a programmer from Hong Kong will expect the plus sign to mean two different things.

  21. By an amazing coincidence... on Earth Tides Trigger Earthquakes · · Score: 1

    A comment I made just a few hours before this article posted mentioned moving the Moon into a geostationary orbit. This would eliminate lunar tides altogether; only solar tides, which are considerably smaller, would be left. To be sure, two sides of the Earth would experience very high stationary tides for a while (with corresponding low-low-low tides at 90-degree angles), until the Earth itself deformed sufficiently to cancel the effect, which probably wouldn't take more than a couple hundred thousand years.

  25. Age concerns on Alvin Submersible Retired After 40 Years Work · · Score: 2, Interesting

    Check out the history of Alvin at the Woods Hole site and you'll see that concerns about fatigue in a 40-year-old pressure hull are misplaced. Alvin has been repeatedly overhauled, with pressure hull and other components replaced. The vehicle has undergone recertification by the U.S. Navy every few years, most recently in 2002. In fact, Alvin has gone deeper in recent years; until 1994 the DSV was only certified to 4000m, not the present 4500m.

    However, the next Alvin will be larger (27 more cubic feet in the pressure sphere, adding about the volume of a good-sized coffin!) and have greater range, both horizontally and vertically. As "Rosco" pointed out above, operating two DSV's at once would be much more expensive. And frankly, any lesser facility than Woods Hole that can afford to operate a DSV would probably prefer to build their own.

    Still, I'm sad to hear Alvin will be retired. Alvin was the first name I learned in deep-sea research as a child, as Jacques Cousteau was the first for shallower waters. A long and brilliant career, averaging (even with overhauls and most of one year stuck on the sea floor) better than a dive every four days for forty years.
