  1. Re:Funny, but lame on How Can We Convert the US to the Metric System? · · Score: 1

    As far as I understand it, relativity does not apply to quantum mechanic oscillations ... maybe that's why Einstein didn't like the q.m. I guess the movement is in the same frame of reference ... so go a head bring out the measurement tools

  2. Re:Europe burns my ass on The European Grand Challenge · · Score: 4, Informative

    One of the main military policies of the US is to be an early adopter and thus on the forefront of every military technology (pratically every technology, besides eco-related :-)) , therefore EU or any other will always be copying the US in some way

    Some comments on the EU Galileo (GAL) project and differencies to GPS (Nav Sys / US):
    - GAL - Civilian (public and pay services), GPS - (public and military services)
    - GAL works in cojunction with GPS and GLONASS (Russia), GPS is not meant to work with other systems (first adopter)
    - GAL and GPS both are augmented by overlayer system like WAAS and EGNOS
    - GAL has a rescue service with return link (SAR Beacon), this is actually 'copied' from GLONASS :-) (USSR first adopters) ... FYI: works like this: you activate beacon, signal picked up by sat. relayed to ground, emergency services signaled and confirmation to beacon is relayed back.
    - GAL has an important integrity signal relayed with nav.signal, to tell uses if the system is actually performing, nice to know if your placing a 100 ton concrete slap (EU first adopters)
    - GAL will work well over most of the globe, GPS has places where the constellation is sub-optimal (like nothern EU contries), GLONASS is very poor at the moment.

    Basically there is some copying going on, but I would say it's more a re-working with a broader perspective. The main point is Galileo is non-military, not hooked up to an early-response-system, and not hooked up to an total-annihilation system :-(

    Yes, I'm European and work in the Galileo project, call me French if you like (but I'm not).
