Controlling the needle's height is a minute electric current that should not flow at all, according to classical physics. Reason: there is nothing to conduct electrons, the carriers of electric current, across the insulating vacuum that separates needle from surface. But modern quantum theory says that a few electrons will jump anyway. Indeed they do, and since the number that jump depends on the size of the gap, the microscope's circuitry can continuously readjust the needle's height by monitoring the amount of current flowing between its tip and the object. The device "is completely new," said...
...crossed the molecular beams in a vacuum, which agitated the molecules. They then used mathematical and experimental methods to determine the velocity and energy content of the resulting reactions, which take place in less then a trillionth of a second...
...formulation of these plans. It included discussion with the Masters, House Committee Chairmen and the Committee on College Life. The Undergraduate Council was kept informed through its representatives on the Committee on College Life. In the nature of the case, the 350th committee members took the lead where a vacuum existed. I am grateful to the members for all the time spent through the spring and summer to plan these events. I hope you will accept and enjoy the festivities in the spirit in which they are offered. A.C. Epps Co-Chairman of the 350th Committee Dean of Students
...preservatives, and protects human health by killing parasites like trichina worms in pork and bacteria like salmonella, which causes food poisoning. Irradiation, they note, can extend shelf life. "We see the day when you can go into a supermarket and buy a barbecued chicken that has been cooked, vacuum-packed and irradiated. It can sit on the shelf for eight years, and all you'll have to do is heat it up," predicts Physicist Martin Welt, founder of Radiation Technology...
...know, inside the Planck length and the Planck duration you have this space-time foam where the quantum fluctuations from matter to non-matter really have very little meaning, mathematically speaking. You have a Higgs field tunnelling in a quantum fluctuation through the energy barrier in a false-vacuum state, and you get this bubble of broken symmetry that by negative pressure expands exponentially...
