Now this is where Joseph Wilbrand comes into play, in 1863, German chemist Joseph wilbrand found a very yellow dye called trinitrotoluene, as a dye though, it was a mediocre dye, it wasn't very stable, and soon better yellow dyes came along. So trinitrotoluene was put on the shelf, and forgotten about for a while. TNT's explosive capabilities weren't even realized until years after its invention. Its explosiveness went unnoticed because TNT has a fairly high activation energy. Another German chemist Carl haussermann, found In 1891, he could just go back
Harry H. Laughlin’s Influence on Nazi Sterilization Law Harry H. Laughlin was a leading eugenicist in the eugenics movement of the United States, the first major eugenics movement in the world. However, the idea of eugenics has been around since ancient times. In his Republic, Plato suggested the idea of selective mating to strengthen the guardian (upper) class of the time, but it was in Great Britain that ‘eugenics’ was created. Sir Francis Galton, cousin to Charles Darwin, first coined the term eugenics in his book Inquiries into Human Faculty and Its Development, taking it from the Greek word eugenes, meaning “good in stock.”
Tea in China is not only a beverage, I 've come to understand that it is a great deal more than that; it 's an art, a custom, and above all a lifestyle. For over 3000 years humankind has been developing a plant that has incited poems, led to the foundation of trade routes and molded human civilization. With its foundations in China, the tea plant has a rich history, and is encompassed by a fascinating culture. During my travel to Hangzhou, my Chinese friends told me interesting stories of China, and the legend of Shen Nong, the “divine farmer”, who taught the Chinese the art of growing tea leaves and agriculture as a whole. The official origins of tea can be traced down to southwestern China in the Yunnan province, where it was first used
Electrical charge is static electricity, or electricity that does not move. The knowledge of electricity dates back to 600 B.C. While the Greeks did not know they had discovered static electricity, they observed that rubbing fossilized tree resin, or amber, with animal fur made the resin attract dried grass. In 1600 AD. An English physicist named William Gilbert wrote books on the attractive nature of amber and used the Latin word "electricus" as a description. Several years later, another Englishman was inspired by Gilbert, his name was Thomas Browne.
While informing the community about his beliefs in germ theory, Louise Pasteur was often ridiculed by the scientific community who preferred the Miasma theory. In 1864, Pasteur held a presentation in front of many famous scientists and intellectuals where he conducted experiments to prove points. The majority of the scientists accepted germ theory after the
“I saw the crown of France laying on the ground, so I picked it up with my sword.” On December 2, 1804, Napoleon Bonaparte boldly crowned himself Emperor of France. He wished to show that he was taking power, not being granted it by the church. From 1804 to 1814, then again in 1815 for the Hundred Days, Napoleon ruled. Much controversy evolved during his reign over whether he was advancing or reversing the spirit of the French Revolution.
Herbal ephedra, which is also known as Ma huang, Chinese ephedra and epitonin, is the world's oldest medicine. The Chinese discovered ephedra in the form of the Ma Huang plant more than 5,000 years ago and it is the basis of Traditional Chinese Medicine. A 1999 UC Berkeley study tells us that the Chinese took sun-dried stems from this ancient plant and ground them up into manageable pieces for use in teas. These teas are still used in many societies, especially in the American Southwest.
However, in 1889, Lars Edvard Phragmen, a Swedish mathematician, was skeptical about Poincare’s claim; that if asteroid’s trajectory is from a fixed point, it would ultimately stabilize towards another fixed point. Poincare rewrote his paper with regards to the problem brought up by Edvard Phragmen. Although Poincare did not succeed in perfecting his work in celestial mechanics, it was still remarkable for him to come up with periodic solutions of the three body problem. Poincare showed the difference between true and intermediate orbits and that is one of the important factors in modern’s day when designing
History In ancient Greece fennel was known as “marathon”. This is because it used to grow in the field where one of the great ancient battles was fought and was called the Battle of Marathon. In the 1300s, it was a staple food in the palace of King Edward I of England.

Also, he had offered to sell the gun to anyone, including the Confederacy and foreigners. Many Gatlings were sold to England, Austria, and Russia and to South American nations.
Borglum found his happiness and talent in sculpting massive art work. He designed and constructed several different sculptures, one of which was a six ton marble head of President Lincoln that was later donated to The Library of Congress in 1908.
