  1. Re:Hardware emulation on Retro-Computing with FPGAs · · Score: 1

    As I understand it, write-once FPGAs can run at much higher speeds than the SRAM-based volatile ones. It's a trade-off.

  2. Re:Hard Evidence Suggests Otherwise on We Are Not Related · · Score: 1

    Hey, horses and donkeys can produce offspring, but they aren't fertile. This hybrid of which you speak might not be either.

  3. Re:Why not? on Downloading The Mind · · Score: 1
    Paraphrasing someone whose name escapes me:

    If the brain was simple enough for us to understand, we'd be too simple to understand it.

  4. Earth-Sun baseline? on A Telescope The Size Of The Earth · · Score: 1

    If you were to build a space-based radio telescope and nudge it over to one of the earth-sun trojan points, you'd have a 1 A.U. baseline. Is this technically feasable? How well does this sort of thing scale?

  5. Re:Russian efficiency... on For Want Of A Soyuz · · Score: 1
    I'd rather use a million dollar ballpoint than wonder where that broken pencil point has got to....

    If you're wondering why that's bad, try dumping some pencil shavings inside your PC.

  6. Re:New Motto! on Space Shuttle External Tank Webcam · · Score: 1

    Given the design of the Apollo programme command modules, I would have to say that it's more likely that if the tank re-entered in a stable attutude (ie not tumbling), it'd be arse-backwards.

  7. Re:Not liftoff on Space Shuttle External Tank Webcam · · Score: 3, Insightful
    The shuttle main engines have been placed central to the mass of the joined shuttle/tank. The OMS engines (Orbital Maneuvering System), being placed much higher, are not. I expect the shuttle would tumble in orbit if the OMS were activated with the tank attached.

    The reaction-control jets will have similar troubles. Remember the control problems the astronauts in Apollo 13 faced when trying to control the LEM with the command/service modules still joined?

  8. Re:'Laws' on Book Review: Voodoo Science · · Score: 1

    All scientific laws are "theories", and to dismiss any of them as being _just_ a theory misses the point of why they are so defined. A _good_ theory is one that is testable, and has a lot of supporting observations. You won't find many better than the Thermodynamics laws. If you have the aptitude to challenge said laws, good luck, and say Hi for me to Sweden's king, but if not, you might as well regard them as truth. The truth is : Free energy machines are impossible!
