Hi everyone! This month we\'ve been quite active uploading videos that is whyhere is the latest video before we upload a top secret video.Did you know that sometimes the greatest discoveries made by peopleare extremely accidental? And who knows maybe if it wasn\'t for these accidental discoveries,maybe they would have never been made.That would be very frustrating. Let\'s get started. Accidentaldiscoveries. Once upon a time there lived a guy, whose name was Percy Spencer.He grew up poor and if that wasn\'t enoughthe only relative he had left was his aunt. He was forced to hold down a few jobsto provide for her and himself.Later he decided to join the US marine corps, gotinterested in wireless network, he began studying it andhe got the hang of radio technologies. He was so knowledgeable that in 1939 he beganworking at the Raytheon company. This is amilitary industrial company which suppliesequipment and weapons in the USA. So one dayhe was working on radar inventions standing next to a runningmagnetron, he reached inside his pocket for a chocolate bar but it went off,I mean melted and he was like, what happened?He took corn and ran an experiment with it.As you must have guessed it the popcorn started popping. I mean the cornstarted popping. And he realized that microwaves can reheat food.This is how microwave oven was invented.It is worthy of note, however, that other peoplehad noticed that too but were not as impressed.The corn in my pocket is popping, seemslike it is extremely hot in here. That is how the legend goes. Lots of sources quote itand the Raytheon site tells this story about the chocolate bar too.I don\'t see reasons to doubt it. Later in life Percy Spencer receivedlots of patents and awards. This is howthe first microwave oven Radar Range looked like. It was installed ona naval ship and was as tall as a grown-up man andit was two times as powerful as an ordinary microwave ovenwhich you probably have at home and cost 5000 dollars.Today this is about 60 000 dollars. There lived anotheroutstanding Spencer but in this case Spencer was his name.Spencer Silver who worked at the 3M company. You know thiscompany well even if you don\'t know it. It was started in 1902 and it dealt witheverything that was sticky.Here is a diode strip and a 3M branded sticky tapeBy the way they also invented a scotch tape. Yes, scotch is a name of the a companyrather than of a product. Surprising facts every day. Subscribevideos on this channel are not uploaded every day. So Spencer waslooking for a new super sticky material which could beglued to something and would be hard to remove. But as a result he discovereda weak glue. It could glue a piece of paperand the paper could easily come off without being damaged.Do you see what I am driving at? He needed a strong glue,not a weak glue. That is why he failed tofind a use for such a glue. Another man,Arthur Fry, who also worked there figuredhow to use this glue and came up with press and peel stickers.Later there was founded the Post-it company. Todayyou can buy their products in any stationery store.This is a truly genius invention. Life would have been so much more complicated withoutthem. He should have won a Noble prize.You probably know Alfred Noble. He was a chemist and scientist.We mostly remember him by his insituition of Noble prize.However, if it wasn\'t for one mistake, maybe this prize would have never been instituted.Noble has invented lots of things anda lot of them were used in the military industry and used for destruction,for instance dynamite. He also had a brother, Ludvig Nobel.Eventually he died. So when his brother woke up one dayhe started reading a newspaper and read about the death of Alfred Nobel.A seller of death. A funny story. Journalistsconfused his named with his brother\'s name but this instance moved Alfred tochange his will and testament because he didn\'t want to be rememberedas a bad guy with dynamite in his pocket.He wrote that he wanted people who make most significant contributions into the developmentof humankind to receive his money. Sohere is the question. Did he succeed in improving his reputation?I think he rather did because most probably before this edition you didn\'t know that hehad a reputation of a bad guy.We have a bad reputation. Should we do some charity?Free dynamite, free dynamite. Hey, it is free!Speaking of explosions, here is a story from my childhood. One day I was beingdriven in a car with my mom and uncle. A lorry was driving byand all of a sudden it spilled crushed stones and some bits bumped into the front window of our car.It felt like an explosion and shards of glass flew at us.And of course they sank into our skin. I got awaywith the least amount of cuts because I sat at the back of the car. Even at that age I wondered whyin films glass doesn\'t shatter when it is shot at, bullets only leave small holesand glass doesn\'t shatter. It turned to be true andthe glass of our windscreen was made of was very cheap.The glass your windscreens are made of is called laminated glass.It was invented by a chemist and an artist Edouard Benedictusand it was an accidental invention made when he was working at his workshop,dopeed a jar which didn\'t shatter but only cracked with a \"spider web\".It didn\'t shatter because it had been filled with nitrocellulose, whichwhen evaporated left a thin film on the surface of the glass.Later he glued two sheets of glass this way and gotlaminated glass. He decided to patent his invention but didn\'tstart mass production of it because it wasn\'t cheap to lauch such production.Only many years later peoplestarted using this glass in the eyepieces of gas masks. Only after that Henry Fordbegan using such glass in the production of his cars.Here is another equally interesting story about how a Swiss inventionattracked the world\'s attention, how science and pure accident locked in a battle,about how it started a chain reaction and about how I should stop punningwhen started telling a story. Now I am going totell you how hook-and-loop fasteners, the things that are so hard to live without,were invented. Hook-and-loop fasteners are used everywhere in clothing, at homeand even in the space. All of this is now possible due to a mere accident.In 1941 a Swiss engineer, George de Mestral, was walkingin the Alps with his dog. Upon returning home hestarted removing burrs from his clothesand his dog\'s fur. As you might know theyalways irritate when you go for a walk to a field. This time hedecided to look at them under a microscope. Burrs stick to clotheswith their natural hooks. It took him 10 yearsto work out how to mechanise production of his hook-and-loop fastenersand patent them. It was challenging for him to choose the right material andeventually he chose nylon. Another challenge waspeople because everyone laughed at him and saidthat his invention would never be necessary. Foolish enviers,what else could we expect from them? Ladies and gentlemen, I would liketo introduce to you a person who doesn\'t care. Do you like ice-creme?I love fruit popsicle the most. It tastes bestin hot weather. But the truth is it was invented not in hot weather andabsolutely accidentally. An 11 year old boyFrank Epperson was running experiments with fizzy drinks outdoors. He mixed lemonade withwater with a stick and left it outside, the temperature outside droppedbelow zero and when he returned he noticed thatthe mixture froze and when he tried to pull the stick out,he lifted it along with the beaker. Ta da, he got a fruit popsicle.Later on he filled a patent and in 1924 he was granted itand he named his invention popsicle. That\'s how this far-fetched story goes butthis is what he himself tells. What can we do. By the way speaking of sticks,you all must know whatviagra is. This is a music girl band and something else. This medicinewas invented accidentaly. Back then scientists tried to create a medicinewhich would dilate blood vessels and help bloodflow.It was supposed to help cure anginaбCoronary artery disease and similar diseases. They synthesizedsildenafil concentrate which theyt began testing.Volunteers didn\'t experince any improvements around their chests but they diddown below.The Pfizer company quickly realized that this medicinecould be used for other purposes. That is why there was no question as to whetherit had benefits. It was patented.All the inventions I have mentioned so far would have been invented anyway,but sometimes the sooner things are discovered, the better. Penicillin was alsodiscovered accidentally and saved a countless number of people.Penicillin is an antibiotic with antibacterial properties.Now it is extracted from such a fungus as penicillium.You can often see such mold in buildings,on food and so on. Many of you don\'t know that it is one of the mostsignificant inventions in the world.I mean discovery of the properties of this fungus. A scientist Alexander Flemingwas studying properties of staphylococcus in his laboratory.This is a type of bacterium which causesdeadly diseases. He decided to take a rest,went somewhere with my family for a month. What did he see when he returned?He saw mold in one of his Petri dishes,like the mold we can see on bread that went off. But he didn\'t see badbacteria around the fungus. This is how it all began.Now Fleming\'s laboratory is a museum.I think it is worthy of mention that back in 1893Bartolomeo Gosio discovered the first antibiotic from another fungushe collected from a rotten corn. This discoverywas forgotten, later it was rediscovered by other people andturned out to have serious side effects. Grab the rubbish.I don\'t have time. I will grab it later. I forgot my smartphone. Here is anotherstory about how someone forgot something. One day in 1879in an Ira Remsen chemistry laboratory a Russian chemist Constantin Fahlbergwas working on something when he finished he went home for a mealand he had something that wasn\'t supposed to be sweet,but it was sweet. All because he didn\'t wash his hands after work.He is sick. His hands were soiled with some chimicals.My mother would never let such a thing happen. It turned out that heaccidentally synthesized what he would later namesaccharin, in fact he did so a long time ago.Of course he was smart enough not to taste it. It wasn\'t apastry bakery after all. That\'s a weird storyin a sense that Remsen wrote a scientific paper about it,but no one cared. Later Fahlbergbegan writing about it himself and named this chemical saccharin. This is how it all began.He enriched himself while the chemistry professor wassomewhat left behind although he was a \"co-author\".Can you really let some smart scientists who will steal your achievementsenter your laboratory after that? In the endI would like to ask you what you know about that device above yourcomputer screen, about web camera? Of course it wasn\'t invented accidentaly,but its use was very funny.In 1921 the first web camera wasplaced in front of a coffee machinein the Cambridge university. It was a very small dimensionblack and white image and it was displayed on the employees\' computerswho worked in another tower of the universityin order for them not to come when the coffee machine was empty. Give them like for their creativity.Give a thumb uop too if you like the video. Thank you so much for watching the video.Check everything yourself. As usual links are down in the description.Of course I haven\'t told you all the stories so we haveI have what to share with you in the future. Besides even nowadays strangediscoveries are made. This is Scientific Research Center,how can I help you? You have found broacasting?Do you even have an idead about how many smrties like you come tous with thier unique inventions? You have come to tell us aboutaether theory which has made all scientists laugh. Time machine, infinite engine...This is a scientific institution, not a circus for dummies.Now listen to me. I was sitting at 2 pm minding my own business as all of a suddenI saw free cartoons, TV channels even though I don\'t havecable TV and so on. I began watching everything.The quality of everything I watched was excellent and Irealized that I had to tell everybody about that.Let\'s get to the point. I suppose have told you everything.Are you making fun of me or you are just stupid? How did you find this broadcasting?It was Yandex TV and there is no need to be so rude. By the way I have prepared a compilationof good films for you. The link is in the description.Sorry, I meant a list, I am a blogger. I have a habit of using the word \"compilation\".Hey, do you know what Yandex TV is? I have a compilationof films.
