and the comedown is a bitch, especially when I pull out the banhammer.
just kidding
Science is cool ok?
Just be careful hey....otherwise I will have to send my white coated mates around. They will open a can of Newton's third law on your a$$.

Hey matt not sure if this is up your alley but did you see below?
Scientists make light pulses dance
IN a sub-atomic light show that has had quantum physicists shaking their heads in wonder, US scientists have made a tiny pulse of light stop, jump from one group of atoms to another and then continue on its merry way.
The experiments, conducted at Harvard University, are consistent with quantum mechanics, the laws governing the behaviour of atoms that Albert Einstein postulated in the 1920s at a time when it was technically impossible to prove him right or wrong.
But the results are still startling, say scientists, because they were so hard to demonstrate and because of their potential applications in technology.
"When I saw the study I did not at first believe it,'' said Michael Fleischhauer, a professor at the Technical University in Kaiserslautern, Germany.
"It shows that we are entering a state of unprecedented experimental control of coherent light and matter waves.''
To get the light beams to dance from one cloud to another, Naomi Ginsberg and a team of physicists at Harvard fired a laser into a cloud of atoms that had been deep chilled into a slow-moving state known as Bose-Einstein condensate.
The pulse of light, composed of particles called photons, was "slowed down from 300,000 kilometers per second to 20 kilometers per hour'' and then to a standstill, its information stored inside the frigid, treacly cloud, one of the authors, Lene Vestergaard Hau, said.
What has happened up to this point is a phenomenon well known to scientists.
But when the the laser was turned off, the light pulse made an imprint - "like a hologram,'' that started moving slowly until it exited the condensate cloud into free space.
"What you wind up with is an absolute perfect copy of the light pulse, but in matter form,'' Ms Hau said.
And then, in a true "quantum leap'', the transformed photons entered into the neighboring condensate cloud a fraction of a millimeter away, where the original light field reappeared.
"It is one of those things that are known from theory but are still counter-intuitive,'' said Mr Fleischhauer, who wrote a commentary which like the study is published in the British journal Nature tomorrow.
The team said harnessing the "matter waves'' contained in atoms would make it possible to design ultra-accurate atomic clocks, gravity detectors and interferometers used to measure rotations and accelerations.
