Here are some of the strangest aviation(航空)ideas in recent history.

    Double-Decker Seating

    In 2015, Airbus filed a patent for a design for a double-decker cabin seating arrangement. Passengers would sit on top of the other, with upper-tier passengers climbing steps or a small ladder to reach their seats. While the design does have some advantages, the idea of climbing a ladder during flight seems unreliable.

    Separated Cabins

    This patent was awarded to Airbus. Rather than waiting for a flight to arrive and be cleaned,passengers could simply board a ready cabin, which would be moved into the plane's body as soon as it was ready. When the plane reached its destination, the cabin would be separated again. Different cabins with different kinds of seating or levels of comfort could be used for flights of different lengths or destinations.

    Windowless Cockpits(驾驶舱)

    For ideal design, airplane noses should be long and pointy. But there's the whole "pilots have to fit in the cockpit" problem. Well, what if the cockpit didn't have to go in the nose of the plane? That's part of the thinking behind this Airbus patent application* which suggests replacing the plane's window with a digital viewing surface. Without a window, there's no reason the cockpit needs to go in the front of the plane —it could go in the middle of the plane, or even in the tail.

    Nap Straps (睡眠吊带)

    Airbus is not the only company in the strange patent contest. Boeing's got its own patent, Nap Straps. With this invention, passengers looking for a nap can find an "upright sleep system^" beneath their seat. In action, the whole thing is somewhat like a traction device for someone who's been in a terrible accident.

    In our increasingly fast-paced, technology-driven world, most adults do not get the 8-10 hours of sleep every night. Things are even worse for those with young children. A recent study showed that 86% of parents in the UK complain of tiredness and about 26% get less than 5 hours of sleep every night. To give tired parents a little relaxation from their tight schedules (时间表), David Lloyd Clubs, a chain of gyms and fitness centers in Europe, has introduced a napping (小憩)class!

    As the name suggests, the hour-long group class, described as a way to " refresh the mind, improve moods, and even bum the odd calorie (卡路里)", does not involve any hard exercise. Instead, the members are guided through 15 minutes of light stretching (伸展)to help them relax. Then, they are encouraged to lie under the blankets of a comfortable bed, cover their eyes with an eye mask, and take a nap for 45 minutes. With music playing in the background and the room set to the perfect temperature, they can be assured of the best possible sleep. The class is now being offered at just one place. If popular, they will be expanded (延伸)to other David Lloyd Clubs.

    Do you know the good points of nap? A study conducted by Pennsylvania's Allegheny College found that midday naps not only help participants feel well-rested, but also enable them to deal with stress better. A follow-up study carried out at the University of California at Berkeley concluded that a 45-minute nap in the middle of the day helps to improve the learning abilities. The good news is that you do not have to make a trip to the U. K. to join this latest exercise fashion. You can get involved with the comfort of your own bed. So, go ahead and encourage your entire family to try a napping class.

    People like to post their selfies(自拍照) on social media. To know more about it, scientists at Syracuse University in New York recently did a research and came up with some surprising findings.

    People who post selfies and use editing software to make themselves look better show behavior connected to narcissism(自恋), the researchers said. Makana Chock, a professor from Syracuse University, said because social media is mostly used by people to share unimportant information about their lives, it is a good place for people to "work towards satisfying their own vanity." Those "likes" under their Facebook selfies make them feel good.

    Besides, people who post group selfies show a need for popularity and a need to belong to a group, the research found. Some people feel "peer(同伴) pressure" to post selfies and some follow the popular belief that if there is no picture of an event or experience, it did not really happen. "Anyway, it shouldn't be seen as negative. People get sense of satisfaction especially when they get likes. And it does no harm," Chock said.

    Other findings from the study include: There are no major differences on how often men and women post selfies and how often they use editing software. But men who post selfies showed more of a need to be seen as popular than women who posted selfies.

Chock said posting selfies on social media is not all that different from what people have done for many years. On trips and special events, our parents and grandparents used cameras instead of phones to take photos. They would bring back photos to show friends and family. You had no choice but to look at them. You probably commented about how nice everyone in the photos looked, especially children and the person showing the photos. They were happy to hear your comments. That was the old way of "clicking like". On social media, however, people can decide not to look at photos — even if they click "like".

A clever technologist took steamboat inventions and turned them into the first commercial steamboat service.

Although Robert Fulton did not invent the steamboat, as is commonly believed, he played an important role in making steamboat travel a reality. He was born in Pennsylvania in 1765. As a young man, he set out to make his name as a portrait painter. His career took him to Europe and into the orbit of people with the power to support him politically and financially.

Fulton entered London society after he painted Benjamin Franklin's portrait. While abroad, Fulton left the arts for a career in shipbuilding. He was interested in the recently-invented steam engine, and thought it could be used to power ships. Fulton's vision was not original; many others had entered the field, and the unfortunate inventor John Fitch had built a working steamship already. But like Henry Ford, Fulton's talent lay not in the invention but in the product's application in the marketplace.

Fulton didn't focus entirely on the steamboat. In 1804, he tested the first submarine successfully, which he had built for the British Royal Navy. His invention would make him a celebrity upon his return to the United States two years later. Fulton's partner Robert Livingston obtained an exclusive license for steamboat services on New York's Hudson River. It was time for Fulton to deliver.

To build an efficient, reliable steamboat, Fulton used a special English steam engine. The ship's bottom was flat and its stern was square. The steamboat Clermont made its debut (首次亮相) on August 17, 1807, steaming up the river from New York to Albany, and it soon entered commercial services. The hilly terrain of New York made water transport faster than land transport, and Fulton's boat — formerly known as the "North River Steamboat" — was a hit. Within five years, Fulton would be running services on six major rivers plus the Chesapeake Bay, and bring in great profits.
