CURIOSITY IS NATURAL !

Many associate the progress of science and technology throughout the history of mankind, with the imperative of military progress. In short, how to kill increasingly effective led to the development of human and technological developments in all areas of industrialization (in support of the war effort) to the use of atomic energy, medical advances, especially in surgery, and various inventions that make our currently lives easier - have emerged and developed in one way or another related to the need to create your advantage on the battlefield.

* One of the invention is from a low American company named Kimberly-Clark and absorbent material which is referred to Cellucotton (the combination of pulp and cotton). This material was used to obtain the first surgical pads. U.S. company representatives toured paper mills in Germany, Austria and Scandinavia in 1914 and identified on this occasion a material five times more absorbent than cotton. Once the United States entered World War I in 1917, military doctors began using surgical pads made ​​from this material. But only after nurses understand the benefits of these pads for their own hygiene, Kimberly-Clark American company registered huge gains.

* Another product born in the context of the Great War is a tissue paper. Selling sanitary napkin suffer while the women are ashamed to ask these from sellers men. Only in the early 20s, after the war, the idea was born sanitary napkins produced by hot pressing of the same material used to produce sanitary pads. After a series of experiments that were more or less successful, sanitary napkins were first born in 1924 under the brand name "Kleenex".

* UV lamp appeared in a context where, in the winter of 1918, about half the children born in Berlin suffering from rickets. At that time, the exact causes of the disease were unknown, but the disease was associated with poverty. A doctor Berlin, Kurt Huldschinsky, observed that his patients whom he had treated rickets and very pale. He decided to experiment on four so pale and sick children of rickets, exposing them to mercury-quartz lamps that emit ultraviolet rays.

As the treatment continues, Huldschinsky little ones noted that bones become stronger. In May 1919, with the summer sun, he put the little ones to the beach. The results of this experiment were received with great enthusiasm. Subsequently scientists have realized that bones need to be solid calcium, calcium and vitamin D is absorbed by the action that is, in turn, produced by the body under the influence of ultraviolet rays. Poverty and malnutrition brought about by the First World War led to the discovery of treatment for rickets.

* The transition to summer time - the idea of ​​giving the clocks forward one hour in the spring and fall back one hour that was not new at the beginning of the Great War. Benjamin Franklin suggested in a letter sent to The Journal of Paris in 1784 which would be the benefits of transition to summer time. World War I, however, have to make this change. Faced with a huge shortage of coal, the German authorities decreed that on April 30, 1916 watches to be given an hour before so 23:00 becomes 24:00, resulting in an extra hour of daylight from the next morning. What began in Germany as a way to save fuel for heat and light in time of war, and then spread rapidly to other countries.

* Tea bags were invented to address any issues of war. They were invented by an American retailer of tea in 1908, which aims to sell single portions (and cheap) to prepare a cup of tea. Incidentally, some of its customers have escaped, inadvertently, these paper bags in the cup with hot water, and the rest became history. A German company, Teekanne, but copied this idea during the Great War, including the front rations cotton tea bags. The name chosen for this product was the "bomb tea."

* Wristwatch was not invented specifically for soldiers in World War I, but this accessory began to be increasingly used in conditions of war. Before, men who could afford, used to wear pocket watches with chain. During the war, however, became very important to coordinate perfectly certain military actions - such as the synchronization of artillery barrages on certain sections of the front - and manufacturers of watches have created pieces that could be worn on the hand, while leaving both hands free to keep the gun or if aviators, flight stick.

Even one of the most famous watches today, luxury model Tank, Cartier, comes from 1917 when French manufacturer Louis Cartier chose as inspiration for his new model wristwatch new Renault tanks.

* Vegetarian sausages were invented by Konrad Adenauer, the first Chancellor of Germany after the Second World War. During the first World War, Adenauer was mayor of Cologne and as the economic blockade imposed on Germany by the British began to make its effects felt, Adenauer was faced with the need to feed the city threatened by starvation. He began to use a mixture of rice flour, barley and corn Romanian origin to make bread. Everything seemed to go very well until Romania entered the war on the Entente side and Adenauer did not have access to corn.

With this bread "experimental" Adenauer came to experience and soy sausage that was used as a substitute for meat. Initially, this book received the name "Friedenswurst" or "sausage peace". Adenauer asked to be recognized herein and to obtain a patent from the German Imperial Office for Inventions, but was refused. According to German regulations on the content of sausages, sausage meat free sausages were not considered. Strangely, Adenauer had more luck with the UK, Germany opponent then. On June 26, 1918 King George V patented soy sausages.

* The zipper was invented by a Swedish immigrant origin, Gideon Sundback, who settled in America, where he became chief designer of the company Universal Fastener Company. His concept of fasteners for clothes and shoes, without buttons or laces, was taken over by the U.S. military, especially the Navy, was used during the Great War uniforms and boots marines intervening in the war on the Entente side.

* Another invention verified its usefulness in the Great War is stainless steel. I have to thank Harry Brearley of Sheffield for the idea of ​​a steel does not rust and does not corrode. As mentioned in the archives of the city: "In 1913, Harry Brearley of Sheffield achieved what is considered as the first steel does not rust or stainless steel - a product that revolutionized the metal industry and has become an important component of the modern world."

Before the Great War British Army alloys look better for his guns. The problem was that the gun barrel while deformation due to firing. Harry Brearley, metallurgist from a company in Sheffield, was called to perform some tough alloys. He added chrome steel. The story goes that the results of the first experiments cast scrap yard factory, but later noticed that these were the only samples that have not rusted in the scrap heap were thrown.

* Aviation communications have emerged as a necessity, all during the first World War. Before the Great War, the pilots had no way to communicate with each other or with ground personnel. Radio communications technology was available, but was developed in particular during World War at Brooklands and then at Biggin Hill, UK. The first attempts to integrate wireless communication devices on planes have been hampered by the loud noise produced by aircraft engine. Before that pilots had to scream or to make hand signs to understand each other. Communication problem was finally solved by the invention of a pilot headphone with integrated microphone and speakers, headset that managed to block most of the noise of engines. This way radio communication between pilots paved the way for the enormous progress made by the civil aviation after the war.
