Petroleum Technologies Timeline - Greatest Engineering Achievements of the Twentieth Century: "1920s-1940s Nylon, acrylics, and polyester are developed

An assortment of new compounds derived from byproducts of the oil-refining process enter the market. Three of the most promising new materials—synthesized from the hydrocarbon ethylene—are polystyrene, a brittle plastic known also as styrofoam; polyvinyl chloride, used in plumbing fixtures and weather-resistant home siding; and polyethylene, which is flexible inexpensive, and widely used in packaging. New synthetic fibers and resins are also introduced, including nylon, acrylics, and polyester, and are used to make everything from clothing and sports gear to industrial equipment, parachutes, and plexiglass.

Can You Heal Yourself with Homeopathy? - Inbox - Yahoo! Mail

Can You Heal Yourself with Homeopathy?: "You may be surprised to learn that high-potency homeopathic remedies are diluted to the point where they do not contain any of the original substance -- yet they continue to have powerful healing properties. This is an aspect of the emerging field of energetic medicine. Energetic medicine heals by affecting the electrical and electromagnetic activity of the body -- the means by which cells communicate with one another. Magnet therapy and light therapy also are examples of energetic medicine.

In homeopathy, researchers now believe that the original electromagnetic frequency of the source materials imprints itself on the fluid used to produce the remedy. Because the human body is 70% to 80% water, a fluid medium is an effective way to transmit information throughout the body.

Does this sound far-fetched? Remember that practitioners of Western medicine used to claim that acupuncture and chiropractic were nonsense -- yet now these alternative therapies generally are accepted as legitimate. Researchers at a number of major universities are now studying homeopathy's applications in energetic medicine. I believe we will be hearing much more about this therapy in the years to come."
