    Undergrad Can Sound Waves Travel at the Speed of Light?

    I'm afraid my conception of the compressibility of BEC is somewhat out of date. I rejected at once the idea of infinite compressibility but did consider cheek to cheek density a possibility. Probably because I always thought of zero terperature neing a cold, dead state (similar to deSitter state...

    Undergrad Can Sound Waves Travel at the Speed of Light?

    Anyone know of experiments on sound through a Bose-Einstein condensate? Should be pretty fast. Could a BEC be compressed? Another stray thought; What would be speed of sound through a compressed plasma of quarks and gluons?

    Graduate What Defines Local vs Non-Local Interactions in Quantum Entanglement?

    Read the paper and THEN judge the author. Like I said in the previous post, there are dozens of recent papers on the subject, not just arXiv, browse the journals, take your pick. Whatever floats your boat, ttn.

    Graduate What Defines Local vs Non-Local Interactions in Quantum Entanglement?

    ttn, relax and take a look at this: http://arxiv.org/PS_cache/quant-ph/pdf/0502/0502016.pdf VI. CONCLUSIONS There were two basic elements to all proofs of non-locality: the fact that the de Broglie-Bohm interpretation of a 2-particle singlet wavefunction generated non-local forces on...

    Graduate What Defines Local vs Non-Local Interactions in Quantum Entanglement?

    ttn, there is nothing *hidden* and once the particles are prepared there are no *variables*; all properties are set before the particles are separated.

    Medical Can Brain Scans See Depression? [NY Times]

    Seems to me scanning the brain to find out what is going on psycologically is like xraying a computer to find out what progam is running. Bah, humbug.

    How about Can ultrasonic waves create extreme temperatures inside gas bubbles?

    Pressure is force, force acting on mass is acceleration, more force gives more acceleration.

    Medical Shrimp have the world record for impulse conduction speed

    Sort of an aside to the main topic, myelin serves several purposes besides insulation. It structurally protects, it is a conduit of neutrients and waste, it serves to bundle the nerves for organized routing, allows bending without kinks, allows stretching and some more that I can't think of...

    News The Impact of Alito's Nomination on Individual Rights and Government Power

    An *experienced* judge surely must have a lot of personal equity in their previous decisions. Baggage is another name for it. Would it affect future decisions? Perhaps. I like the idea of Mier being out of the club, so to speak.

    Genes to live a really extended lifetime

    I have read there is a strong link between life span and metabolic rate. Longer lived species have slower biological processes, especially metabolism. A fly in the soup is than mankind has been evolving more or less independent of Darwinian evolution since brain development reached the stage...

    News The Impact of Alito's Nomination on Individual Rights and Government Power

    Which is more important, how a judge would rule on a single issue like Roe v Wade , or all of the other cases (thousands) that the judge will face in a 20+ year tenure? Single issues are the most dangerous basis I can think of to support a SC Judge

    News The Impact of Alito's Nomination on Individual Rights and Government Power

    Meirs may not have prior juducial experience but she has good sense and a history of making sound decisions. Extensive experience is detrimental if that experience is in making bad judgments.

    High School Why does the sun generate white light?

    Because it's so damn hot! The hotter a star the broader the spectrum, the whiter the light.

    Undergrad Saturn's Moon Iapetus: Big Wall & Geology Mystery

    If the moon is rotating very fast it may have driven debris from the rings to it's equator. Or, fast rotation during a rapid cooldown causing the crust to be crunched into a moutain ring by contraction of the main mass. I think I like the first guess better.
