THEY FOUND AN ANCIENT MONOPLANE IN A PYRAMID IN EGYPT !!!!
it's 1898 and you're taking part in excavations in Sakara this place not far away from Cairo is full of ancient tombs and pyramids you're in your Indiana Jones mood and hope to find something really phenomenal to become famous gold manuscripts treasure maps mummies of famous pharaohs wait a wooden bird you're really disappointed as it looks like a regular toy an old one but still little do you know that years later someone would propose that your bird was actually an ancient monoplane so the artifact nicknamed the Sakara bird is made of a sycamore tree the birdie has a wingspan of just seven inches and weighs around 40 grams a perfect original souvenir from Egypt I would say it's over 2 000 years old and looks pretty plain without any carvings of feathers or other intricate ornaments it has a beak and eyes though which makes our fine look like a hawk the emblem of the deity Horus its tail is rather unusual as it's squared looks weirdly upright and it seems like the sunken part of it was the place where I now missing piece humans love solving a good mystery so there have been several attempts to explain the use of the birdie first quite simply is that it was a ceremonial object the second idea is that it was a toy for a child from some well-law family it could have been some sort of boomerang which was a popular Concept in ancient Egypt then there was a theory that the bird had been used as a Weathervane but this one has been debunked as the figure doesn't have any holes or markings except for the one made at the Museum in Cairo to fix the exhibit on a stick so there was no way to hang it in the past almost a century after the bird was found egyptologist Dr Khalil masiha proposed a new theory that it could have been a model of a monoplane he believed the bird was missing a horizontal tail plane otherwise it had its wings set at a right angle similar to that of modern planes it could have worked to generate the aerodynamic lift necessary for flights Dr masiha also claimed that it was common at that time to place miniature models of technological inventions in tombs so did the ancient Egyptians really invent the plane in 200 BCE that would make their Wright brothers who are considered the inventors of Aviation really really upset they made one of their first flights only in 1903. there's just one way to know for sure and that is to test the model but you know the ancient Museum in Cairo would unlikely let one of their cherished exhibits fly around like a toy that's why glider designer Martin Gregory built a similar model this time of balsa wood and concluded that even with the missing tail plane the plane wasn't much of a flyer case solved not really this didn't sound convincing enough to the History Channel so they invited an aerodynamics expert to build another replica of the bird he tested it in weather conditions similar to those in Egypt and was impressed with the little plane's abilities so if they did invent the Prototype of a plane back in the times of pharaohs it would be a good example of an upart that's an out of place artifact an object that's way ahead of its time in terms of technology or history and the Sakara bird isn't the only example of such a revolutionary concept in 1901 a group of divers retrieved the anti-cathera mechanism from an underwater shipwreck near the Greek island of antacira it's been dubbed the world's first analog computer and it's currently dated around 100 BCE the bronze mechanism could tell the position of the sun moon planets and stars as well as the lunar phase the dates of upcoming solar eclipses and even the speed at which the moon moves through the sky no one's sure who used it and how or where it was made but it's obvious that it's extremely precise and way too advanced for its time the first flushing toilets in the world were invented in the middle of the 20th century just kidding the ancient Minoans on the Mediterranean island of Crete and the Indus Valley Civilization both came up with this Brilliant Invention at the same time around 4 000 years ago the plumbing and sanitation were so well done that no one managed to design anything better until 2 000 years later one ancient minoan lavatory was discovered at the palace of canosos it looks like it had a wooden seat set over a tunnel that directed water from a rooftop Reservoir to an underground sewer other varieties got water from jugs only the super rich people could afford all this Glory so if you wanted to shop for Real Estate back then the flushing toilet would be a Telltale sign you were in the rich neighborhood automated doors became a cool seemingly new invention back in 1931. but the technology behind them is actually much older think the first century CE old mathematician and engineer Heron of Alexandria came up with a hydraulic system to open and close Temple doors to bring it into action you need to light a fire to produce heat there was a brass pot under the fire half filled with water the inventor connected the brass pot to containers that acted as weight when the fire was burning the water moved into the containers they went down and pulled the ropes it was nothing like a supermarket door that opens in front of you before you even have time to think Heron's door took hours to open and there was no way to stop the process that's why they only opened the doors once a day before people entered the temple to add some mysticism at the temple during ceremonies spooky looks like the first ever battery was invented in Baghdad around 2000 years ago a German archaeologist found this oval-shaped clay jar in 1938 scientists are still not sure what purpose it served and who exactly invented it there is a theory that it was used for electroplating objects with precious metals when they filled it with a weak acid like vinegar the battery produced around one volt of electricity another theory says it was a vessel for sacred Scrolls would you like to buy contact lenses designed by Leonardo da Vinci himself in 1508 he invented a Glass Lens with a funnel on one side you were supposed to wear it with water inside to improve your vision sounds a bit uncomfortable doesn't it so around a century later French scientist Renee Descartes decided to improve the idea and make the cornea contact the future lenses contacts because they contact your eyes get it the glass tube with liquid did help improve Vision but blinking was sadly impossible two and a half centuries later new technologies in the glass industry let scientists design contacts that would fit in the eye and even let the wearer blink thanks guys still those lenses were made of heavy blown glass and didn't let the eye breathe about 50 years later contacts became plastic lightweight unbreakable and scratch resistant but still covering the entire eye and then in 1948 an English Optical technician accidentally sanded down a plastic lens and figured out they'd still be in place even if they covered only the cornea imagine you're living in 19th century London and need to send a message to New York it would have taken about 10 days to get there by ship so when delivery time went from days to hours in 1858 it was a true sensation the first message was sent by Queen Victoria herself it was all made possible thanks to the transatlantic Telegraph cable running under the ocean sadly the new cool invention only lasted a few weeks it took years to bring it back to life that's it for today so hey if you pacified your curiosity then give the video a like

WHY SILICON VALLEY IS HERE !
These are the blooms of prune trees. Located in a geologic trough, the Santa Clara Valley in California was once known as the Valley of Heart's Delight due to its farmland filled with flowers and fruit, including prunes. How did a region known for its fruit and flowers... become an intellectual capital? During World War II, American engineer Vannevar Bush basically led wartime R&D. And in 1945 he published an essay called “Science: The Endless Frontier”. Bush reported to President Roosevelt that the pioneer spirit is still vigorous within this nation. Though focused partly on problems like the war against disease... the report also set an expectation... that science and continuing science funding... was necessary for the public welfare. Just a few years later, the National Science Foundation resulted as Harry Truman wrote, Henry Ford to promote industrial development in national defense. This funding meant facilities like NASA's Ames then called NACA... and Navy stations near San Francisco, provided a continuing engineering talent base to the San Francisco Bay Area. That was paired with proximity to Stanford University... the college that had greater land resources than cash. Built from the land grant of Leland Stanford the university was land rich. You can see in this early proposal how a small campus was surrounded by farmland. But Stanford didn't have a ton of cash. The region had a lot of unrealized potential... and one of Vannevar Bush's former students... wanted to realize it. Frederick Terman was a professor of electrical engineering at Stanford as well as an iconic name in radio science. He worked on stuff like jamming Nazi radar during World War II and he also wrote a radio engineering textbook that sold hundreds of thousands of copies. Even before Terman was appointed university provost in 1955 as a professor and as a dean, he sought ways to develop the Valley of Heart's Delight. This 1950s land use study shows that Stanford intended to use some of its land primarily for the campus and residential development. Stanford developed the Stanford Shopping Mall to help remedy their lack of cash. It's still leased by the university today. This is their California Pizza Kitchen. More importantly... Terman helped the university develop Stanford Industrial Park... today called Stanford Research Park. This is what it looked like in 1953. The park provided affordable 99 year leases to tenants with a strict development plan to preserve the character of Palo Alto Construction. They insisted on low buildings and preserved grassland... that the Valley of Heart's Delight was known for. But it was more than just a development on the university's land. From the beginning, Terman imagined a new cycle. Stanford to companies... to Stanford to companies... [repeating and overlapping] to Standford to companies... As he said in one interview for Palo Alto 75th anniversary... “And I would say university made a major contribution... to the development here.” “But then the companies made a major contribution to the development of those parts of the university that contributed to these companies.” He encouraged this in many ways including allowing professors to spend time in corporate roles and get corporate paydays... and helping companies enroll employees as Stanford students. He proudly clipped this article about faculty eggheads becoming millionaires. And he gave speeches about how Stanford is also a source of highly trained manpower for those companies... at a time when such manpower is in short supply. Crucially, this cycle wasn't predicated on silicon or semiconductor companies. Stanford Industrial Park was open for any tenant that wanted to be near Stanford. Houghton Mifflin, the book publisher staked to claim in the Stanford Industrial Park. Other hi-tech but not computer-focused companies also found spots there, as shown in this 1960 picture. Here's Terman at the announcement of a Stanford Research Park building for SpinCo, a maker of centrifuges and division of a larger company looking to expand in Palo Alto. Stanford's landholdings quickly changed. You can see how it expanded through 1955 with 120 acres into 350 acres by 1960. Terman explicitly said this cycle would not only affect the Bay Area but the national labor market. It worked and in electronics focus grew from Terman’s own interest in engineering. West Coast electronic firms produced 22% of the US’s electronic market in 1960, and it kept growing. This was a competition between regions. Terman said if the Midwest continues to plod along in electronics... it is destined to become the peon group... in the nation's electronics industry. He also argued that growth industries depend on brains... and the best source of brains is the nation's major universities. Proximity of markets no longer will play a key role. This is the Palo Alto garage where Hewlett-Packard was founded. Terman had been a teacher. And his personal solicitations helped bring them to the West Coast. And later, a short drive away in Stanford Industrial Park... where HP secured a 40-acre site. Stanford Industrial Park became a platform for any successful industry that might emerge. William Shockley's Shockley Semiconductor Laboratory is widely credited with starting the Silicon semiconductor boom... and Fred Terman solicited Shockley to start his business in the Valley. He did so in nearby Mountain View. Shockley Semiconductors became a demonstration of the final cycle that Terman initiated: Engineers in the ecosystem would found new companies in the same area. Employees split off Shockley to form Fairchild Semiconductors in Mountain View... and then those employees split off to form Intel locally... and so on and so on. This paired with development of more recognizable companies that started in the industrial park. Renamed the Research Park in 1970. Xerox's Palo Alto reach center, PARC was located there. “This is an experimental office system.” “It's in use now at the Xerox research center in Palo Alto, California.” As venture capital grew in the 1960s... bearby Sandhill Road was an obvious location due to its proximity to the Stanford epicenter. By 1971, journalist Don Hoefler former publicist for Fairchild Semiconductor labeled the region Silicon Valley for a series of articles. It was an allusion to the silicon chips that had taken over the valley. As Hoffler wrote... The pace has been so frantic that even hardened veterans of the semiconductor wars... find it hard to realize that the Bay Area story covers an era of only 15 years. The Valley became home to Oracle... and Next and Adobe and Sun Microsystems. And from Netscape on powered forward... in the first dotcom boom. “In 1994 and 95... Netscape was known as the fastest growing company in the industry... with all the requisite valley attributes.” And even in a remote work era: Meta, Apple, and Google have all maintained Silicon Valley... as a substantial hub. Terman’s vision made that cycle possible. And today's Silicon Valley has fewer prunes... but it remains in all its complicated ways... a Valley of Heart's Delight. Hey, thanks for watching this history of how Silicon Valley became Silicon Valley. But I've got— One more thing. Is that corny? No? Should I have not done that? Anyway. The map that I use of Stanford Research Park... It goes up to a certain point in the video... but it actually comes from a historical survey... that continues in time. So I want to show the rest of that to you here. By 1965, it is up to 500 acres. That's the yellow area. The light green area shows you that it's ballooned to 575 acres by 1970. By 75, it's at 600 acres. That's the dark green. And then you've got the blue, which shows you up to 1980 which expands Stanford Research Park to 700 acres.

Afzal AhamedPublished 9 months ago in EducationSecond world war
Second world war It is the largest armed conflict that humanity has known. A deadly war that involved tens of millions of fighters around the world. Let’s summary of the main events of World War II. At the end of World War I, Germany and its allies are defeated and held solely responsible for the war. With heavy sanctions imposed upon them, the Austro-Hungarian and Ottoman empires are dismantled, while Germany has to repay what many consider an unreasonable debt. Its colonies and some of its territories are ceded to the victors, and to Poland which is recreated. These sanctions are seen as humiliation by the German people. The German economy is weakened by excessive debt and suffers hyperinflation. National mints try to address this by printing banknotes, causing a devaluation of its currency. Between 1914 and November 1923, the value of the mark grew by 1,000 billion. The following year, radical measures are taken to halt inflation and stabilize and revive the economy. But in 1929 the Wall Street crash in New York causes the worst economic crisis of the 20th century.
Heritage lived on for ages and propelled others to emulate their example.
Sometime in the distant past, in a distant land, there was a lovely and prosperous realm. The realm was controlled by an equitable and insightful ruler who was cherished by the entirety of his kin. The realm was wealthy in assets and individuals were blissful and content.
