As Boyd recalls, he then remembered that Robert Millikan, a Nobel Prize - winning physicist and the head of Caltech from 1921 to 1945, also had to contend with removing copper oxide when he performed his famous 1916 experiment to measure Planck's constant, which is important for calculating the amount of energy a single particle of light, or photon, Boyd wondered if he, like Millikan, could devise a method for cleaning his copper while it was under vacuum conditions.

Quantum mechanics tells us that the vacuum of space - time is teeming with random quantum fluctuations, which create waves of energy.

(Twenty - seven kilometers of tunnel underground Designed with mind to send protons around A circle that crosses through Switzerland and France Sixty nations contribute to scientific advance Two beams of protons swing round, through the ring they ride»Til in the hearts of the detectors, they're made to collide And all that energy packed in such a tiny bit of room Becomes mass, particles created from the vacuum And then...)

This might have practical implications in quantum computing, as ours is a world of constant fluctuation — even a vacuum is alive with vibrations of energy.

Presently, dark energy — a mysterious substance that seems to be associated with the vacuum of space itself — is pushing the universe outwards more strongly than gravity pulls in, causing the universe to not only expand but to do so faster and faster.

Sexual maturity, the loss of the sweet fuzzy puppy fuzz that is replaced with the dog hair that will clog up your vacuum for the rest of his life, and that beautiful day when he figures out once and for all exactly where the potty for puppies is makes a dog's human proud and gives us the sense that our time and energy is being well spent.

Keith Kloor, the journalist and Collide - a-Scape blogger, e-mailed me this morning asking if I agreed with his post noting an apparent «narrative vacuum» on energy and climate.

If a black body with a fixed - rate energy source is in radiation - rate - equilibrium with the vacuum of space at 0 Kelvins, placing additional material separate from but surrounding the black body will likely cause the temperature of the surface of the black body to change in such a way that energy - rate - equilibrium is re-established for the black body.

And yes, a stationary molecule in a vacuum in deep space, with no interractions with other molecules which recieves little or no radiative energy, will aproximate to near absolute zero.

If the object are NOT in contact with each other (i.e., not connected by a good conductor, but RADIATING at each other with vacuum or air or some good insulator between) the hot to cold rule does not apply except to the NET transfer of energy.

I believe that if in the vacuum of space you place a blackbody object with (a) a constant (i.e., unchanging energy per unit time) internal thermal energy source, and (b) internal / surface thermal conduction properties such that independent of how energy enters the blackbody, the surface temperature of the blackbody is everywhere the same and you place that object in cold space (no background thermal radiation of any kind), eventually the object will come to a steady state condition — i.e., the object will eventually radiate energy to space at a rate equal to the rate of energy produced by the internal energy source.
