  1. Have you actually read the book? on Roger Penrose and the Road to Reality · · Score: 2, Informative

    Come on. Be honest.

    Scattered throughout the book are sections that speculate on Platonism, and half-dead cats, and astronauts orbiting black holes and anthropic principles.

    The rest of the book is math. And some of it is hard. Maybe iI was supposed to learn about "Clifford Algebra" from juvenile stories about a Big Red Dog. And maybe, I somehow missed the high school geometry lessons about fiber bundles. Perhaps I've simply forgotten my nursery school lullabies on algebraic topology, but I've found that if you actually read the book for the content, and not for the "mindblowin' shit", it's a tough read. Not impossible, mind you. It's just less literary than Goedel Escher Bach.

    A narrowscreen TV has a 4:3 ratio, thus the diagonal forms the hypotenuse of a 3:4:5 right triangle.

    A widescreen TV has a 16:9 ratio, and the diagonal forms the hypotenuse of a 9:16:18 right triangle.

    Thus, a 25 inch archaic style TV will have the same height as a 30 inch widescreen TV.

    Ask yourself what you mean by "pure evolution theory." The phrase is a remarkable syntactical construction that subtly implies a distillation of all the myriad loose ends of evolution into one or two simple concepts. Yet you present no evidence that you have a good working knowledge of those concepts.

  10. Re:In this kind of setup... on DirecTV's 1st MPEG4 Satellite Launch Successful · · Score: 1

    Er, no.

    Let me give you an example. The Fox affiliate in Baltimore is an UHF station broadcasting on channel 45-- plain old NTSC. It also offers a digital ATSC service on channel 46. This ATSC program stream is divided into two subchannels. One (45-1) is a 720p HD stream, which is quite watch-able. The other, (45-2) is a 480i SD stream, which is quite poor in comparison. The same programs are shown on both channels, though 45-1 is widescreen.

    But if you don't have a ATSC tuner you can't watch 45-2. If you do have a ATSC tuner, both subchannels will be accessible, upconverted or downconverted as needed. Thus, 45-2 appears to be superfluous.

  11. Re:It's the economy model, stupid on Airbus A380 Completes Maiden Test Flight · · Score: 1

    The baseline 7E7 has a 14500 km range. They've added a 6500 km model, but the original conception was this:

    Traditionally, the longer hauls were between large cities-- for example, if you wanted to fly from (e.g) Cleveland, OH to Glasgow, Scotland, one might fly from Cleveland into New York, transfer to a connecting flight (on a long range airplane, such as a 747) to London-Heathrow, and then connect to a third flight from London to Glasgow.

    The 7E7 would allow airliners to ditch the hub system and offer flights between Cleveland and Glasgow.

    NTSC still has nasty color artifacts. In theory, a SD ATSC stream, given a high enough bitrate, looks as good as a DVD. But most broadcasters starve their SD streams, either because they multicast several SD channels, or because they insist on simulcasting in both High and Standard definition. Hmm, shall I watch the fuzzy, washed out version, or the sharp, high resolution version? Decisions, decisions....

  18. Re:Duh, analog of course. on Budget LCD Monitor Round-up · · Score: 1

    When the Apple IIgs came out, many of the early reviews had sidebars explaining why a "analog RGB monitor" was better than a "digital RGB monitor"-- an analog CRT could display 4096 colors, while a digital monitor was limited to, IIRC, 64. Some Apple IIe users already had RGB monitors, but those were typically digital (EGA), and thus incompatible with the GS.

    IIRC, the EGA connection was a parallel interface. Increasing the number of colors would mean increasing the number of signaling lines, which would all need to be kept in sync, and free from interference. Serial interfaces would be too slow, and so analog rgb monitors were popularized.

    Since that time, serial technology has improved to the point where a switch back to digital is now possible.

  20. Re:Home Theater Recommendation? Heard of Prof. Aud on Home Theatre PC Guide · · Score: 1

    If you have widely spaced speakers, the center speaker helps improve the illusion that the actors on screen are speaking.

    On a PC setup, the fronts are closer together, and so the center speaker becomes less important. But for a standard size living room, a center speaker is almost a given.

    Rear surround speakers (as opposed to the standard left and right surround speakers) are not so important, but DTS-ES and Dolby Digital EX DVDs do make use of them. Even if you shy away from such mindless thrills as "Lord of the Rings" or "Star Wars", the two advanced surround formats--Dolby Prologic IIx and DTS Neo:6 can use the rear speaker(s) to good effect. Both of those surround formats, incidentally work reasonably well with stereo music.

    Consider that if you decide to upgrade to a 6.1 or 7.1 surround system later, installing the extra two rear speakers will either involve snaking unsightly speaker wires under rugs, along walls, and so on, (ruining whatever aesthetic advantage the original installation may have had) or hacking through drywall and playing around with fish tape.

    Best to at least wire for a 7.1 setup.

    I plan to celebrate April (and May, and possibly June) by reading Roger Penrose's The Road to Reality an entertaining tome of but 1100 pages that purports to teach the reader all the math he needs to understand modern physics. Penrose is the ultimate optimist, but I must confess, I'm having difficulty after only chapter 8 (Riemann surfaces and complex mappings) of 34. Maybe, if I don't pay too much attention to the math, I'll breeze right through it. But then, that would defeat the whole purpose of Math Awareness Month.
