PARACHUTE inventor



A parachute is a device for slowing down one's descent while falling to the ground. Parachutes are used to skydive from airplanes, to jump from very high places, and to help slow down the descent of spacecraft. Parachutes are also used to slow down some race cars. The early parachutes were made from canvas (a strong cotton cloth). Light-weight (but very strong) silk cloth was then introduced for parachutes. Modern-day parachutes use nylon fabric.

The idea of using a parachute to fall gently to the ground was written about by Leonardo da Vinci (1452-1519). The first parachute was demonstrated by Louis-Sébastien Lenormand in 1783 of France - he jumped from a very tall tree carrying two parasols (umbrellas). A few years later, some adventurous people jumped from hot-air balloons using primitive parachutes. The first person to jump from a flying airplane (and survive the fall) was Captain Albert Berry, who jumped from a U.S. Army plane in 1912. Parachutes were first used in war towards the end of World War 1.

The first postal stamp

The one inventor who can truly be said to have left his "stamp" on the future is almost unknown in the world of inventors. Indeed, who ever heard of Rowland Hill (1795-1879), the man who invented the postage stamp, that little piece of gummed paper which everyone uses today?

The son of an English schoolmaster, Hill thought up a way to reform the postal system that was currently in use - an impractical system in which the postage, based on weight and distance, was charged to the addressee. He advocated a uniform rate of postage to be paid by the sender instead - using stamps.

As is often the case with inventions, several people claimed to have had the same idea. Yet one thing is certain: Hill, who was later knighted by the queeen, is the one who finally carried the project through. As the universally recognized inventor of the postage stamp, Sir Rowland has since been honored over and over again by postal services throughout the world, in particular on the centenary of his death (1979), the bicentenary of his birth (1995) and the 150th anniversary of the invention of the postage stamp (1990). Among the most beautiful commemorative issues printed on those various occasions are a truly magnificent one from Portugal and others from Chile, Ghana and the United Kingdom.

The first postage stamp thus saw the light of day in England - on 6 May 1840 to be precise. Its name? The Penny Black. Printed in black and white, it bore the profile of Queen Victoria, who was so pleased with her likeness that she had the drawing maintained on all the subsequent issues that were put out of the stamp throughout her sixty-year reign.

Postage stamps quickly spread from England to the rest of the world. In 1843, they were adopted in Brazil and in the Swiss cantons of Zurich and Geneva, and in 1845 the canton of Basel issued its famous Basel Dove - the first stamp to be printed in three colors. France, Belgium and Bavaria started putting out stamps in 1849, and other countries soon followed suit.

The first stamps were imperforate: perforated stamps, which are easier to detach, were only invented in 1851. The originator of this idea was Henry Ascher - an Englishman as well.

Blue Jeans


Blue Jeans, invented in 1850
Working as a canvas salesman in San Francisco during the California Gold rush of the 1850s, Levi Strauss made a keen observation. He noticed that pants of prospectors and miners could not withstand the wear and tear of their profession. Strauss decided to stitch some canvas together and sell them as pants. What they lacked in comfort, Strauss's pants made up in durability. When he discovered that using denim -- canvas dyed blue to better conceal stains -- produced even more popular and comfortable apparel, an American fashion mainstay had been established. Once the workwear of cowboys, miners, and ranchers, blue jeans are today worn by people of all walks of life, at work and play.

The return of steam


The future of automotive technology may lie in the past. Bruce Crower, 77, an auto-racing designer with a thriving business in San Diego, has invented a hybrid steam engine in which water is sprayed into a traditional gasoline-powered cylinder, turning waste heat into usable energy. How much energy? Enough to travel 40% farther on a gallon of gas.

Amazing, True Inventions

Never underestimate the power of the human mind to invent new and creative things. In this three part series, we’ll review some incredible inventions and discuss how one might best describe them in English.

company called Flavor Spray Diet has an Internet Web site called (naturally) www.flavorspraydiet.com.

What makes this company "different," is that they specialize in making sprays which actually smell and taste just like your favorite very fattening foods, only these sprays have no calories! This also means no cholesterol, and no chances of making you obese.

For example, if you prefer "bacon and eggs" with your glass of water while dieting, just reach for that bottle and spray it on whatever you like.

If you’re British, you can literally spray your entire English breakfast on you, fooling your colleagues into thinking that you actually know how to cook!

Flavor Sprays are available in many different, well, flavors: Parmesean cheese, peanut butter, pesto sauce, banana split, peanut brittle, smoked bacon and even birthday cake! How about some chocolate fudge spray? Yes, we’re not joking folks, this is all very real.

World famous gourmet chef David Burke invented these wonders, yes, America really does have some excellent world class cooks.

Anti-Teenager Repellent
For those of you who find teenagers to be "annoying," or just don’t want them "hanging around" like they’re prone to do, there’s actually a company in Wales, yes, WALES, which actually makes an anti-teenager repellent device!

Shown here above, this machine actually emits a special ultrasonic frequency which people only under the age of 25 can hear!

Next, this same inventor promises to market anti-teenager ring tones for cell phones.

Imagine being able to actually annoy your favorite teenager with whining noises using their favorite toy (their precious little cell phone) that only THEY can hear!

Isn’t technology wonderful, folks?

Time best inventions 2006

Meet Peter. Peter is a 79-year-old English retiree. Back in WW II he served as a radar technician. He is now an international star.

One year ago, this would not have been possible, but the world has changed. In the past 12 months, thousands of ordinary people have become famous. Famous people have been embarrassed. Huge sums of money have changed hands. Lots and lots of Mentos have been dropped into Diet Coke. The rules are different now, and one website changed them: YouTube.

It's been an interesting year in technology. Nintendo invented a video game you control with a magic wand. A new kind of car traveled 3,145 miles on a single gallon of gas. A robot learned to ride a bike. Somebody came up with a nanofabric umbrella that doesn't stay wet. But only YouTube created a new way for millions of people to entertain, educate, shock, rock and grok one another on a scale we've never seen before. That's why it's Time's Invention of the Year for 2006.

But if YouTube is the Invention of the Year, who exactly invented it?

Let's be clear: we know who started it. That would be three twentysomething guys named Steve Chen, Chad Hurley and Jawed Karim. At a Silicon Valley dinner party one night in 2004 they started talking about how easy it was to share photos with your friends online but what a pain it was to do the same thing with video.

So they did something about it. They hacked together a simple routine for taking videos in any format and making them play in pretty much any Web browser on any computer. Then they built a kind of virtual video village, a website where people could post their own videos and watch and rate and comment on and search for and tag other people's videos. Voilˆ: YouTube.

But even though they built it, they didn't really understand it. They thought they'd built a useful tool for people to share their travel videos. They thought people might use it to pitch auction items on eBay. They had no idea. They had opened a portal into another dimension.

The minute people saw YouTube they did its creators a huge favor: they hijacked it. Instead of posting their home movies, they posted their stand-up routines and drunken ramblings and painful-looking snowboarding wipeouts. They uploaded their backyard science projects, their delivery-room footage and their interminable guitar solos. They sent in eyewitness footage from the aftermath in New Orleans and the war in Baghdad—from both sides. They promulgated conspiracy theories. They sat alone in their basements and poured their most intimate, embarrassing secrets into their webcams. YouTube had tapped into something that appears on no business plan: the lonely, pressurized, pent-up video subconscious of America. Having started with a single video of a trip to the zoo in April of last year, YouTube now airs 100 million videos—and its users add 70,000 more—every day.

What happened? YouTube's creators had stumbled onto the intersection of three revolutions. First, the revolution in video production made possible by cheap camcorders and easy-to-use video software. Second, the social revolution that pundits and analysts have dubbed Web 2.0. It's exemplified by sites like MySpace, Wikipedia, Flickr and Digg—hybrids that are useful Web tools but also thriving communities where people create and share information together. The more people use them, the better they work, and more people use them all the time—a kind of self-stoking mass collaboration that wouldn't have been possible without the Internet.

The third revolution is a cultural one. Consumers are impatient with the mainstream media. The idea of a top-down culture, in which talking heads spoon-feed passive spectators ideas about what's happening in the world, is over. People want unfiltered video from Iraq, Lebanon and Darfur—not from journalists who visit there but from soldiers who fight there and people who live and die there.

The videos may not be slick, but they're real—and anyway, slick is overrated. Slick is 2005. The yardstick on YouTube is authenticity. That's why celebrities like Paris Hilton and P. Diddy can compete with a cute sleepy kitty and a guy doing a robot dance—and lose. That's why Peter's crusty, good-natured reminiscences have made him the all-time second-most-subscribed-to uploader on YouTube. That's why Michael J. Fox let his Parkinson's tremors show. That's why politicians have suddenly started to act like real human beings in their campaign ads, and why some—like Senator George Allen of "Macacagate" fame—have been busted for getting a little too real.

Less than a year after its launch, YouTube has become a media giant in its own right. Last month the company moved out of its 30-person office above a pizzeria in San Mateo, Calif., and into an office building in nearby San Bruno. Oh, and on Oct. 16 Hurley and Chen sold the company to Google for $1.65 billion.

With that kind of money behind it, YouTube has to start conducting itself with a little more legal and financial gravitas. That means making money—mostly through advertising—and convincing the TV, movie and music executives who find copyrighted material on YouTube that it's a revenue opportunity and not grounds for litigation. The learning curve is still steep. "The people marketing content see it as a great new platform, but the legal side of the business doesn't know how to react," Hurley says. "We have instances where someone within the company uploaded something, and the other side's asking you to take it down."

But YouTube isn't Napster. It already has partnerships with NBC, CBS, Universal Music, Sony BMG and Warner Music. And come on—it's the one place on the Net where people willingly, knowingly click on ads, like Nike's legendary clip of sharpshooting soccer star Ronaldinho. If you can't find money on YouTube, you're in the wrong economy, buddy.

YouTube is ultimately more interesting as a community and a culture, however, than as a cash cow. It's the fulfillment of the promise that Web 1.0 made 15 years ago. The way blogs made regular folks into journalists, YouTube makes them into celebrities. The real challenge old media face isn't protecting their precious copyrighted material. It's figuring out what to do when the rest of us make something better. As Hurley puts it, "How do you stay relevant when people can entertain themselves?" He and his partners may have started YouTube, but the rest of us, in our basements and bedrooms, with our broadband and our webcams, invented it. (...)

AEROSOL SPRAY CAN

The forerunner of the aerosol can was invented by Erik Rotheim of Norway. On November 23, 1927, Rotheim patented a can with a valve and propellant systems - it could hold and dispense liquids.

The first aerosol can (a can than contains a propellant [a liquefied gas like flurocarbon] and has a spray nozzle) was invented in 1944 by Lyle David Goodloe and W.N. Sullivan. They were working for the U.S. Department of Agriculture and were trying to find a way to spray and kill malaria carrying mosquitos during World War II for the soldiers overseas. The "clog-free" spray valve was invented by Robert H. Abplanal in 1953.

The first spray paint was invented by Edward H. Seymour in 1949. Seymour's wife Bonnie had given him the idea of an aerosol applicator for paint. The first spray paint he developed was aluminum colored. Seymour formed the company, Seymour of Sycamore, Inc. of Chicago, USA, which is still in operation.
