  7. Resolution Resolved (Re:Price pressure... Really?) on 13.8MP Kodak Tops Previously Leaked Canon · · Score: 1

    Uh... resolution does not "vary with the square of the pixel count." The pixel count is the total number of pixels, and therefore determines the resolution. It's not the number of pixels per side, or something, which is what you perhaps had in mind.

    Actually, that turns out not to be the case. Resolution refers to the ability to resolve, and is generally defined as the maximum number of alternating black and white lines that can be clearly seen per unit distance in an image. Camera makers generally use the megapixel shorthand to give an indication of resolution, but you can generally assume that the pixels are arranged in an approximately 3x4 aspect ratio, and make your assumptions based on that. But regardless of that ratio, image resolution is limited by the spacing of the pixels in any linear direction.

    It makes sense if you think about it: In order to double the resolution of an image (simply, to see the same amount of detail at twice the subject distance), you have to quadruple the sensor's total pixel count. All else being equal, images from a 4-megapixel camera will have twice the resolution (resolving ability) of a one-megapixel camera. Not as impressive for the brochure, but still a physical fact. Assuming a fixed aspect ratio, image resolution varies with the square of the pixel count, and that's just the way it goes.

    Personally, I'm waiting for Dr. Arroway's camera in the movie Contact:

    Maybe that will be Nikon's response!

  9. Price pressure... Really? on 13.8MP Kodak Tops Previously Leaked Canon · · Score: 4, Insightful

    "The best news is that new products like this will push prices down on the 4-6MP cameras at the high end of the consumer level."

    IMHO, they won't have a real impact on that market. Canon's excellent G2, a 4-megapixel camera, is currently selling at a street price of $600-$650. Others are in that same range, between $500 and $1000. Do you really think that someone considering the purchase of a $700 camera is going to be swayed by a $4000 camera with less than twice the resolution (noting that resolution varies with the square of the pixel count)? And remember, interchangeable lenses means they're extra, so the actual price difference is actually greater.

    I'm really excited about these new cameras and sensors, and I think they're going to make a big impact in the film-dominated pro market, but to think they're going to generate price pressure on sub-$1000 cameras would be like Toyota dropping Camry prices to compete with the newest Lamborghini.

    CONTOUR: Latest News
    August 16, 2002 -- 1 p.m. (EDT)
    Search for CONTOUR Continues


    Mission operators continue to listen for a signal from CONTOUR.

    Using its 34-meter antennas, NASA's Deep Space Network stations are scanning the spacecraft's expected path beyond Earth's orbit, attempting to pick up radio signals from CONTOUR's transmitters. The CONTOUR team is also awaiting feedback from several NASA-sponsored and other optical and radar sites that have been searching the skies for signs of the spacecraft.

    CONTOUR's STAR 30 solid-propellant rocket motor was programmed to ignite at 4:49 a.m. EDT on Aug 15, boosting the spacecraft out of an Earth parking orbit and onto a trajectory to encounter two comets over the next four years. The spacecraft was too low for DSN antennas to track it during the burn - about 140 miles (225 kilometers) above the Indian Ocean - and the CONTOUR mission operations team at the Johns Hopkins University Applied Physics Laboratory expected to regain contact about 45 minutes later to confirm the burn. No signal was received, and the team has been working through plans to find the craft along the predicted trajectories for a successful burn.

    CONTOUR's onboard computer was carrying a command that, starting at 6 a.m. EDT today, would have turned the spacecraft and pointed another of its four antennas toward Earth. So far, however, no signal has been received.

    CONTOUR, a Discovery-class mission to explore the nucleus of comets, was built and managed by the John Hopkins University Applied Physics Laboratory, Laurel, Md., for NASA. Additional information about CONTOUR is available on the Internet at: http://www.contour2002.org.

    ...indicate that, assuming the Moon's orbital momentum were bled off at some reasonable (!) rate, that it would spend sufficient time within its Roche limit (5.5*2.42/3.34 = ~4 earth radii) to be torn to bits and redistributed into a massive, chunky ring. Once that transformation was accomplished, the Earth's surface would rapidly restabilize; since the ring would have a somewhat evenly distributed mass, its major tidal effect would be to increase Earth's equatorial bulge.

    Of course, the large number of collisions in NEO among kilometer-and-greater-diameter objects would result in many thousands of catastrophic KT-magnitude impacts, meaning that any current life on earth would be kaput without a primary lunar impact ever occurring.

    Mr. Bailey answered this question well, but seemed to believe that this kind of event was impossible. I'd suggest running an N-body simulation in which a small, massive object such as a black hole passes near the Earth-Moon system, in such a way as to impart a differential acceleration to the two bodies. It's easy to find (by trial and error, if need be) the appropriate criteria for a fly-by that would drop the Moon right in our laps, with little or no lateral motion. I'd guess that this was probably the kind of impact that the questioner envisioned.

Since then I've owned a IIIxe, a Vx, an m500 and an m505, and have been pleased with all of them except the m505.
