They both combine elements of chemistry, metallurgy, physics, medicine, astrology, semiotics, mysticism, spiritualism, and art. It has been practiced in Mesopotamia, Ancient Egypt, Persia, India, and China, in Classical Greece and Rome, in Muslim civilization, and then in Europe up to the 19th century in a complex network of schools and philosophical systems spanning at least 2500 years. Today the discipline is still active but is of interest mainly to historians of science and philosophy, and for its mystic, esoteric, and artistic aspects. Alchemy was one of the main precursors of modern sciences, and many substances and processes of anc emmineb Thu, 26 Apr 2007 09:22:42 GMT http://www.biology-online.org/dictionary.asp This dictionary is based on a WiKi system, which enables everyone to add and update the content.

"Our memory device is soft and pliable, and functions extremely well in wet environments – similar to the human brain," one of the researchers, Michael Dickey, said when announcing the breakthrough. To construct the circuits, the team used a liquid alloy of gallium and indium, set in water-based gels. "We've created a memory device with the physical properties of Jell-O," says Dickey. emmineb Fri, 15 Jul 2011 17:44:24 GMT http://britneyspears.ac/lasers.htm The physics of optoelectronic technology emmineb Tue, 13 Feb 2007 06:30:32 GMT http://www.custom-logic.com/exp/cloth/cloth.html emmineb Sat, 16 Feb 2008 17:12:40 GMT http://www.gladwell.com/1998/1998_02_02_a_pima.htm The Pima are famous now--famous for being fatter than any other group in the world, with the exception only of the Nauru islanders of the West Pacific. Among those over thirty- five on the reservation, the rate of diabetes, the disease most closely associated with obesity, is fifty per cent, eight times the national average and a figure unmatched in medical history. It is not unheard of in Sacaton for adults to weigh five hundred pounds, for teen-agers to be suffering from diabetes, or for relatively young men and women to be already disabled by the disease--to be blind, to have lost a limb, to be confined to a wheelchair, or to be dependent on kidney dialysis. emmineb Fri, 13 Apr 2007 10:04:51 GMT http://qntm.org/destroy Destroying the Earth is harder than you may have been led to believe. You've seen the action movies where the bad guy threatens to destroy the Earth. You've heard people on the news claiming that the next nuclear war or cutting down rainforests or persisting in releasing hideous quantities of pollution into the atmosphere threatens to end the world. Fools. The Earth is built to last. It is a 4,550,000,000-year-old, 5,973,600,000,000,000,000,000-tonne ball of iron. It has taken more devastating asteroid hits in its lifetime than you've had hot dinners, and lo, it still orbits merrily. So my first piece of advice to you, dear would-be Earth-destroyer, is: do NOT think this will be easy. This is not a guide for wusses whose aim is merely to wipe out humanity. emmineb Wed, 21 Mar 2007 08:23:05 GMT http://www.physorg.com/news95575580.html An IBM scientist holds a thinned wafer of silicon computer circuits, which is ready for bonding to another circuit wafer, where IBM's advanced "through-silicon via" process will connect the wafers together by etching thousands of holes through each layer and filling them with metal to create 3-D integrated stacked chips. The IBM breakthrough can shorten wire lengths inside chips up to 1000 times and allow for hundreds more pathways for data to flow among different functions on a chip. This technique will extend Moore's Law beyond its expected limits, paving the way for a new breed of smaller, faster and lower power chips.

The best example I can think of in describing what a gravity wave looks like is to think of a rock being thrown into a pond. Ripples or circles migrate from the point the rock hits the water. An up and down motion is created. With increasing distance from the point where the rock hit the water, the waves becomes less defined (the waves are dampening). Now let's look at what a gravity wave is in the atmosphere. To start a gravity wave, a TRIGGER mechanism must cause the air to be displaced in the vertical. Examples of trigger mechanisms that produce gravity waves are mountains and thunderstorm updrafts. To generate a gravity wave, the air mus emmineb Tue, 29 May 2007 13:42:36 GMT
