What are the Holy Grails of Science that could change our world?
http://en.wikipedia.org/wiki/Theory_of_everything" is the holy grail, I believe. "Sentient computer" or "self-aware computer" AI is not necessarily that intelligent nor self-aware. Interstellar colonization http://en.wikipedia.org/wiki/Space_colonization" "Free energy" would be...- Jim1138

Undergrad Question about sound waves - lengths and related
Stokes' law http://en.wikipedia.org/wiki/Stokes%27_law_(sound_attenuation)" Sound traveling through a Newtonian fluid (i.e. water, air, metal, but not Jello) attenuates by the square of the frequency. 1000 Hz attenuates four time as much over a distance than 500 Hz. Which is why elephants... -

Humans only use 20-30% of their brain
I seem to remember (but don't rely on this) that walking and running is mostly performed by ganglia. The story goes that if you chop a chickens head off, it can walk and run just fine (for awhile). I would imagine that collision avoidance is impaired a bit. Collision avoidance appears to...- Jim1138

Humans only use 20-30% of their brain
If one removes 10% of one's brain, you don't just take 10% longer to solve a problem. You would be totally non-responsive and die if that 10% is your brain stem. You might go blind, deaf, mute, be partially or fully paralysed, loose interest in sex, be unable to remember, etc. etc. There may...- Jim1138

Death by Cell Phone texting What evidence? Compared to what? Far more likely you die from texting then by cell phone "radiations". There is http://www.reuters.com/article/2008/10/02/us-usa-train-crash-idUSN0152835520081002" .- Jim1138

Making bacteria express green fluorescent protein - could it decrease fitness?
It depends on how strongly the protein is expressed. It can reduce the growth rate to zero in extreme cases. If one strain outgrows another by 1%, the first population will be about 2.7X the second in 100 generations (assuming none die).- Jim1138

Graduate What would happen if an ICBM was hit by a 1.3 petawatt laser?
Have you read http://en.wikipedia.org/wiki/Directed-energy_weapon ? The problem with using Lawrence Livermore's petawatt laser http://en.wikipedia.org/wiki/National_Ignition_Facility (NIF) as a weapon is 1) it is huge. It wouldn't even fit on an aircraft carrier. 2) while the peak power is...
