Its all about what promises to be the next fundamental wave of technology - quantum physics. You many see pretty pictures. That is good for public relations since most here would neither understand nor stay awake for the quantum physic questions being answered and asked by those pictures.

Whether it be the creation of new materials, basis of new computer programs, communication and security, converting nuclear waste into safe materials, medical techniques (what does PET scan stand for?), transmission and generation of energy (ie superconductivity), etc. Most research in most technologies now involves various aspects of quantum physics. Unlike the ISS, Hubble has a scientific purpose well beyond pretty pictures.

Stupid Physics Riddle of the Day
 

Q: Why did Albert Einstein cross the road?

A: To get away from Werner Heisenberg. But, when he got to the other side, Heisenberg was there, too!

argh
old =p

wheni was a little kid (hmm not so long ago *laughz) i used to get this dream where i was in a spaceship going to the edge of the universe and i'd get there and there everything was just red when i kept going.
I think that was my brain BSODing on the concept on infinity.

Heres an interesting one
if you have an object that is infinately long, does it have a midde.
