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I'm afraid my conception of the compressibility of BEC is somewhat out of date.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...- kublai

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?- kublai

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.- kublai

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...- kublai

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.- kublai

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.- kublai

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.- kublai

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...- kublai

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.- kublai

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...- kublai

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- kublai

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.- kublai

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.- kublai
