Aerogel was first made in the 1930s by Samuel S. Kistler, who obtained several patents for making a variety of aerogel, including silica, alumina, chromia, tin and carbon.

Mixing four chemicals, which react to form a wet gel, similar to a gelatin dessert creates Aerogel. The gel is then dried in an autoclave, in essence a pressure cooker that applies pressure and heat.

The fact that typical aerogels are between 95 and 99.5 percent porous gives them their unusual characteristics. Because of this highly porous quality they are characterized by extremely high surface area, high thermal and acoustical resistivity, low dielectric constant, and low refractive index. There are other materials that exhibit each of these properties, however, only aerogel exhibits all of these properties at the same time.

Flower essences were first developed in the 1930's by the English physician, Edward Bach. Dr. Bach was a classically trained physician who became a pioneer in understanding the relationship of emotions to the health of body and mind. Today we call this the "body/mind connection." You can also use the tongue-twister, "psychoneuroimmunology." He observed that many physical diseases could be directly related to a person's mental attitude.

Dr. Benjamin Gavish, InterCure's Founder and Chief Scientific Officer, patented and developed a fundamental method of affecting biological rhythms and respiration with external rhythms such as melody, which led to the development of RESPeRATE, the company's first product.

Vibrational essences are a part of ancient wisdom, and have been found in aboriginal cultures throughout the world. The 16th century master physician and herbalist Paracelsus also used essences. The best-known essence maker of the modern world is the English physician Dr. Edward Bach. He re-invented essences in the 1930's, creating the popular Bach Flower Remedies. They are used widely throughout the world. In the past 15 years or so, many new essences companies were founded all over the world.

Answer:It was developed by Dr. Allen Dyer, a world-renowned medical researcher who invented the cardiac defibrillator that went around the globe to revive heart attack victims. Dr. Dyer holds an M.D., a Ph.D. and a pharmaceutical degree. He is the former deputy minister with the Ministry of Health in Ontario, Canada.

Balloons have been around for centuries.  The modern latex balloon that we are familiar with was invented in New England during the Great Depression. A chemical engineer named Neil Tillotson was attempting to make inner tubes using liquid latex, which was a new product.  He was having no luck.  In his frustration is cut out a cat's head and dipped it in the latex.  When it dried he found that he had a cat head.

The first cache was placed by Dave Ulmer near Portland, Oregon on May 3rd, 2000. Three days later, two people who had read about the cache on the sci.geo.satellite-nav newsgroup found the cache and entered their names in its log: geocaching was born! You are welcome to link to any of my pages from your web site but please do not place copies of this site's maps on your own web page. Geocache data has been gathered from geocaching.com, navicache.com, and other sources. We thank them all!

Answer: The short answer is Jesus Christ; Jesus (followed by all his disciples) was the one teaching a first-century Second Coming. The long answer is that Preterism has always been a minor voice throughout Church history. Church fathers like Eusebius of Caesarea, St. John Chrysostom, St. Basil the Great and many others were either Preterists or showed strong Preteristic tendencies.

The mechanical genius Bartolomeo Cristofori invented the piano around 1700. The name piano is actually a shortened version of the Italian term pianoforte, meaning soft-loud, and referring to the fact that the pianoforte could produce sound volume covering a much larger range than its predecessors, the harpsichord and clavichord.

In 1988 gun prohibition activist Josh Sugarmann circulated a paper among anti-gun groups, telling them that they needed a "new issue" to "strengthen the handgun restriction lobby," because their efforts to ban handguns had failed.

Coca-Cola was invented in May 1886 by Dr. John S. Pemberton in Atlanta, Georgia. The name "Coca-Cola" was suggested by Dr. Pemberton's bookkeeper, Frank Robinson. He penned the name Coca-Cola in the flowing script that is famous today. Coca-Cola was first sold at a soda fountain in Jacob's Pharmacy in Atlanta by Willis Venable. During the first year, sales of Coca-Cola averaged nine drinks a day, adding up to total sales for that year of $50. Since the year's expenses were just over $70, Dr.

An aerogel "movie" is a series of 40 images taken of the same minute location of the aerogel collector, with each image focused on a different depth within the aerogel. The focal points range from 20 microns above the aerogel's surface to 100 microns deep within the surface. The "movie" effect is created by moving continuously between the focus levels, which is akin to moving into and out of the aerogel.

Aerogel is endowed with remarkable qualities, including being 39 times more insulating than the best fiberglass insulators. For Stardust, aerogel's most important characteristic is its ability to slow down and preserve particles traveling at high speed. The cometary and interstellar dust particles encountered by Stardust were traveling ten times at speeds of around 20 kilometers (12 miles) per second relative to the spacecraft.

Sailing through a fleet of monohull trailer sailers in 1973, while on an early Piver trimaran, it occurred to designer that the trimaran configuration would be ideal for the trailer sailer. It is light for towing, much more stable, totally unsinkable, and it sails much faster. The only problem was how to fold it down for trailering. Several existing systems were investigated, including telescopic beams, straight hinges, and the 'swing wing' system.
