Throughout the history there have been thousands and thousands of discoveries made by people who did not seek, or close, to what end ended up finding.
1 -. Penicillin The bacteriologist Alexander Fleming, from the decade of the twenties, was very interested in the treatment of infections caused by wounds. In 1929 Fleming , after returning from a vacation, he realized that in a forgotten pile of plates before his departure, which had been cultivating a bacterium, Staphylococcus aureus, had also grown a fungus in the place where it was inhibited growth of the bacterium. It turned out that the fungus “was manufactured” a substance that resulted in death of the bacteria, and the fungus belongs to the species Penicillium , Fleming established that the substance produced would be called “penicillin” . .
2 – LSD Swiss chemist Albert Hofmann took The world’s first acid in 1943 , when it struck a mica lysergic acid diethylamide, a chemical compound which was investigating to stimulate labor. However, he soon discovered that the substance had a power greater than that of almost any other known at the time, so that the dose administered was actually higher than later advised for therapeutic purposes.After ingesting the substance Hofmann felt it difficult to speak intelligibly and asked his laboratory assistant, who was aware of the experiment , to accompany him on his journey home on bicycle , then, by the restrictions of the war period, there were no cars available . During the ride home, Hofmann status worsened, and wrote in his diary that he had everything in his field of vision wavered, distorted as an image in a concave mirror. Although I moved quickly, had the paradoxical feeling that remained stationary . When he got home, he called a doctor and asked his neighbor some milk, believing it would help him recover. Hofmann notes that despite his delirious state, was able to choose lucidly milk for quality nonspecific antidote for poisoning. When the doctor arrived, he found no abnormal physical symptoms other than extremely dilated pupils. After spending several hours terrified , convinced that a demon had possessed his body, that his neighbor was a witch and the furniture of his house threatening him, Dr. Hofmann thought it was completely mad. In his diary indicates that Dr. Hofmann decided not to medicate and preferred sending to bed. Once lying Hofmann felt panic beginning to give way to a feeling of good fortune and gratitude . The colors and sets of forms he saw him with closed eyes now proved enjoyable. It was “fantastic images” that arose before him, alternating one after another, opening and closing circles and spirals and then explode into color sources, and start again, in an endless flow. During his ‘journey’ , acoustic impressions (like the noise of a passing car) were transformed into images. Finally, Hofmann fell asleep and woke up the next day fresh and clear mind, albeit with some body fatigue. has had breakfastwith a sense of well being and renewed life, and found the food delicious. As I walked through the garden, he noticed that all his senses “It vibrated with higher sensitivity, which lasted all day.” .
3 – Saccharin was a young scientist in the laboratory of chemical American Ira Remsen, surnamed Fahlberg , who by chance was discovery. He was in the dining room of the laboratory, when he noticed that the soup had a sweet taste. I was surprised to notice while the cook did not notice anything and was angry with him. After testing, bread and other foods, he realized that everything was sweet. Just then licked his hand and found that during one of the experiments being conducted with coal , looking for new colors reaction, he had created a sweetener. The isolated and patented by the name we all know, the saccharin.
4 – Microwave emitters microwave (or magnetrons) radars supplied the allies in the Second World War. The microwave emitters (or magnetrons) radars supplied the allies in the Second World War . The Spencer Company engineer Raytheon , his pocket of his coat a bar of chocolate, which gave rise to one of the most inventions used in everyday life. At that time the engineer Spencer conducted research with a high frequency generator (60,000 MHz) for use as radar. After a while researching felt a little hungry and decided to eat the chocolate bar in his pocket of his jacket. When he took the candy bar to eat it, found the chocolate melt. The engineer decided to check their experience placing an egg and some popcorn near the generator frequency and then retired. Returning to his lab found that it was full of popcorn and scrambled egg. .
5 – Oxygen Joseph Priestley , chemist British philosopher and theologian, belonged to the Royal Society, but soon left Britain to leave the USA and develop your career as a chemist. He discovered many gases but certainly the most important was that of oxygen . One day, heated mercuric oxide in an incandescent glass, producing a more intense heat any flame, producing a colorless gas that burnt the candle flame more brightly than in the air. Trying to figure out if the gas was harmful, placed inside the bell a lab rat. It was found that the rat lived half hour breathing the gas before dying, but with normal air within the hood, the rat could only live fifteen minutes. Puzzled about the nature of the gas, there was first isolated oxygen without . know .
6 – Cognac The merchants of wine Medieval used to extract water from the wine (boiling) so their delicate cargo better settle and occupy less space in the ship’s cargo; adding it to reach its destination . Much later, some intrepid soul – bet that was a sailor – decided to avoid the process of reconstitution, giving birth to the cognac.
7 – Telescope The great discovery of the telescope , according to some sources, an apprentice of the master manufacturer is awarded lenses Lippershey Hans (1570-1619), who taking advantage of the absence of the master, playing with eyeglasses got a mixture that allowed them to see things much closer. At the turn of the master, and let him know this, inlaid these opaque lenses in a tube, thus inventing the telescope . The great discovery of the telescope , according to some sources, an apprentice of the master lens maker wins Lippershey Hans (1570-1619), who taking advantage of the absence of the master, playing with eyeglasses got a mixture that allowed them to see things much closer. At the turn of the master, and let him know this, inlaid these opaque lenses in a tube, thus inventing the telescope.
8 – Anesthesia The N2O , nitrous oxide, better known by the name of laughing gas, caused in humans generally laughter and occasional fights occasion. It was in a show organized by Professor Gardner Colton in 1844 , where coincidentally the dentist were Horace Wells , with his friend Samuel Cooley. Colton requested volunteers to test this gas and Cooley volunteered for it, causing the gas in it reaction tremendous violence, causing a fight. After the fight, Wells noted the presence of a pool of blood, discovering that his friend had a deep wound in the leg, and what was more surprising, Cooley had not even noticed because of the effects of the gas. Wells became quickly up and began to investigate the possible application of gas in dentistry, asking a colleague to a Foreign chopped a tooth under the influence of nitrous oxide. Thus opened the field of anesthesiology in dentistry .
9 -. Xray History of the X-ray experiments begins with British scientist William Crookes , who investigated in the nineteenth century the effects of certain gases when subjected to power surges. These experiments were carried out in a vacuum tube, and electrodes for generating high voltage currents. He called Crookes tube. Well, this tube being near photographic plates, generated in the same some blurry images. Despite the discovery, Crookes not continued researching this effect. Thus Nikola Tesla , in 1887 , began studying this effect created by Crookes tubes. One of the consequences of their research was to warn the scientific community the chance to organisms biological posed by exposure to radiation.But until November 8, 1895 they were not discovered X-rays, physical Wilhelm Conrad Röntgen , performed experiments with Hittorff-Crookes tubes (or just Crookes tube) and coil Ruhmkorff . Analyzing the cathode ray fluorescence to avoid violet cathode rays producing the walls of a glass tube. This creates an environment of darkness, covering the tube with black cardboard sleeve. When you connect your computer for the last time at evening, he was surprised to see a faint yellow-green glow in the distance: on the near bank was a small cardboard with a solution of crystals of platinum-cyanide of barium, which was observed darkening to turn off the tube. When you turn on the tube again, the glow produced again. Farther removed solution crystals and found that fluorescence was still produced and repeated the experiment and found that the rays created a very penetrating radiation, but invisible. He noted that the rays they crossed large layers of paper and even less dense than lead metals. .
