In 1860, the Henry was designed by Benjamin Tyler Henry in 1860. It was produced throughout 1860 to 1866 in the United States by the New Haven Arms Company. The Union got small quantities of this rifle in the Civil War, it had greater firepower than the service rifle. It took Benjamin Tyler Henry 3 years to design this rifle. The production of these rifles were very limited, about 150 to 200 a month until the middle of 1864.
This all happened in 1879, when the Kelly gang came up with the idea of making armour from mouldboards. They used hammers to beat the material until it could be worn. Kelly’s gang was killed during a shootout however, Ned Kelly lived. His armour now is a very valuable artefact.
In the 1840s, Friedrich Schönbein accidently discovered that cotton soaked in nitric and sulfuric acid can explode when exposed to heat. This property of “guncotton” results from the fact that the protons on the various alcohol groups of cellulose were converted into NO2 groups, in a process known as nitration. This discovery would inspire the search for similar ways to manufacture explosives. It is extremely fascinating and noteworthy to compare how similar the synthesis of TNT (trinitrotoluene) is to the way Schönbein accidently formed guncotton. If you were to start with toluene as your starting material, you can follow similar steps taken by Schönbein to synthesize TNT.
The Chinese came up with all of this before inventing any sort of gun. The fire lance, one of the earliest ancestors of the firearm, was first used in 1132 (Max Distro, 2013). The fire lance consisted of a spear attached to a flamethrower, and it was capable of firing projectiles from a barrel made of bamboo or paper (Max Distro, 2013). It wasn’t until the late 14th century in Europe when the safety and thoroughness of incorporation was improved by wet grinding the ingredients of gunpowder (Max Distro, 2013). The paste was then rolled into balls to make travel and storing more
Purpose: The purpose of this laboratory experiment was to prepare morphine samples via solid phase extraction, and then analyze them using gas chromatography and mass spectroscopy methods. This was done in order to determine the concentration of one unknown sample, interpreting the results based on a generated calibration curve from the GCMS data. Procedure: • Prepare buffers and a calibration curve: o 100 mL of 100 M phosphate buffer with pH 6.00 0.2 using 1.182 g KH2PO4 and 0.1867 g Na2HPO4 o 100 mL of 100 M acetate buffer with pH 4.5 0.2 using 0.291 g NaOAc and 6.454 mL acetic acid o calibration solutions to generate a curve with the points 2, 10, 30, 50, and 80 g/mL o provided internal standard Test buffers with pH meter. Store in
1. Socrates explains that he has acquired a bad reputation, because a prophecy by the oracle at Delphi stated that no one was more wise than him. He is considered the wisest, because he is the only one that acknowledges that he does not know anything. He uses the oracle to explain his mission by interrogating wise men, but if they were wise, it seemed that they were only wise about their own career, and nothing else. In this mission, he tried to prove the oracle wrong, but discovered he was wiser than these men, because the men he interrogated seemed to think they were knowledgeable on subjects when they weren’t.
Throughout the 1900s, there were new ideas that were both accepted and rejected as useful and realistic. Nanotechnology, radio, and plastic were all developed during this time period and were presented in different ways. The ways in which these new technologies are presented and imagined greatly effects its future. The timing of innovations, the speed of its upheaval, its usefulness in society, and economic impacts are critical factors in the development of technologies. On the other hand, the development of wooden airplanes was not as successful because of the process in which this advancement was researched and applied.
My overall reaction to the narrative when I read And of Clay Are We Created was a sense of heartbreak. It was heartbreaking to watch Carle battle with PTSD and Azucena clinging on the tire for dear life while the bodies of her dead relatives held onto her feet. I would say that the story's overall tone is restless. In essence, the narrator walks us through her actions and inner thoughts so that we may understand what is occurring to Azucena and Carle. The lover of the narrator, Carle, is so intensely concerned that she wants to learn as much as she can about the situation.
The next improvement happen in 1752 when James ascough began experimenting with Tinted lenses. He found that different color lenses can cure diseases. In the 1900’s New glasses were prescribed to people with syphilis they had yellow tinted lenses. Sunglasses became more widespread across the world especially with movie stars. There was a major mass production of sunglasses as well.
It wasn’t until 1977 when they made one last attempt at selling the product in Boise Idaho that they caught their break people started buying the note pad. It was in 1977 that 3M patented their sticky pad dated back to Sep 1974. Alan Amron was still trying to sell his product but also wasn’t having any big success with selling his product. He didn’t realize that 3M was even interested in his product since they never called him back. He continued to sell his product along with creating new products.
The first wetsuit was made in 1969 by Jack O’Neil which allowed surfers to go out in even the coldest conditions. These innovations led to companies such as Bilibong, Quicksilver, Bilabong, and Sex Wax, which showed up in the late 60s and early
REVIEW OF LITERATURE Hippocrates summed it up by saying “… not to reduce it is ti incur the reproach of ignorance; to reduce it is to increase the chances of death.” Papyrus Smith, Egypt, 1800BC “Whenever there is a gaping wound, such as that inflicted by the mouth of a crocodile it should be covered with meat” Amboise pare’ (father of French surgery) in 1545 “ the ski must forthwith be enlarged so that there may be free passage for both for pus or matter as also for other things the wound may contain. If there be any strange bodies as pieces of wood, iron, bones, bruised flesh, congealed blood, or the like, whether they come from without or within the body, he must take them away for otherwise there is no union to be expected.” Before
Batteries have been around for a very long time. It is thought that the very first type of battery may have been made by the Parthians around 250 B.C. They lived in Baghdad and made a clay jar with vinegar and a copper cylinder inside with a iron rod sticking out. Batteries have definitely changed since then. In the 1800 an Italian physicist Alessandro Volta invented the voltaic pile, which was made of zinc and copper plates with vinegar with leather or pasteboard between each plate.
Takata was founded in 1933 in Shiga Prefecture, Japan, by Takezo Takada and started to produce lifelines for parachutes, and other textiles for the WWII Imperial Japanese Army. The original name of Takata was Takata Kojo Corporation. Later they incorporated as "Takata". In the early 1950s, the company started to research seat belts.
The early compasses were made of lodestone, (a naturally magnetised ore of iron) and a needle floating in water. It was first used by
