Indoor Skydiving
Have you ever dreamt of flying? Have you ever wanted to experience the excitement of skydiving, but didn’t want to jump out of a plane? Indoor skydiving has opened up a whole new world for you to try flying.
Indoor skydiving is an activity, simulating(模拟)the free fall of a skydive. That means you learn to fly in a column of air produced by a wind tunnel (风道) inside a limited area. Before flying, you need to wear certain equipment to protect you. And each of you is equipped with an instructor that helps you learn to control your body while flying. But you aren’t trained to be more aware in the sky as a normal skydiver.
To be an indoor flyer, you can be at all ages. Fear of height or lack (缺少) of experience won’t stop you from trying. The only real limitation preventing people from flying is weight limit. Countless physically challenged flyers have safely flown with the help of experienced instructors.
Although indoor skydiving gets its name from skydiving, the similarities between the two are actually very few. The one they are in common is in the sense that they both share the freedom of flying.
However, in traditional dives, skydivers usually step out of a plane from more than 10,000 feet high, while indoor skydiving just needs flyers to lean forward and lie on the air. Also, being an outdoor activity, skydiving depends on the weather. The wind, rain, or snow can cancel your plans to jump. Indoor skydiving removes this effect from the picture. Normally, a skydive lasts just between 45-60 seconds, but tunnels allow skydivers to fly longer and as much as they like.
While most people put skydiving in the must-do list, indoor skydiving is much more than that! What used to take skydivers tens of thousands of jumps and years of experience can be learned in a relatively shorter period of time. Skydivers could be trained at lower cost compared to being trained in the sky. Because people of all ages can fly, children are quickly becoming some of the most talented skydivers. Thus, all these will certainly benefit the development of skydiving.

“It's phenomenal,” said Simons. “We have this ability to understand other people so remarkably that their victories literally become ours. Our testosterone literally responds to their victory.
Professor Robert Cialdini at Arizona State University came up with the term BIRG— Basking In Reflected Glory—to describe the intense pride fans feel when their teams succeed. It can be used as a verb, as in, "Seahawks' fans are currently BIRGing up a storm." The counterpoint, as coined by researchers C. R. Snyder, Mary Anne Lassergard and Carol E. Ford, is the concept of CORFing—Cutting Off Reflected Failure.
This leads into another concept, that of cognitive bias, also known as confirmation bias, which causes fans to help explain away defeats by blaming outside factors, such as referees. I'm sure it would also help explain why Seahawks fans rallied around Richard Sherman after his postgame interview, rationalizing behavior that was widely criticized by many fans with no vested interest. It could also explain the notion of "eustress", invented by endocrinologist Hans Selye to refer to a combination of euphoria(极度愉快的心情)and stress, such as that resulting from watching tense sporting events. Indeed, it's much of the appeal.

【推荐2】I remember the first time I saw a skateboarder roll past me when I was 14 in the early 90s. The skater wove in and out of the schoolchildren. He moved in such a smooth and cool way. He flowed through the crowds in the same way that water finds its natural route. It was the coolest thing I’d ever seen. Why walk to school when you could skate? After serious saving and a request for early birthday funds, I found myself in the skate shop and got my first skateboard.
What I didn’t know then was that this first attempt was the beginning of a voyage that would never end. Information and experiences were exchanged and shared with friends. Videos of legendary professionals — Mark Gonzales, Rodney Mullen, Chris Miller — were circulated and pored over. After making a thorough study, I realized that dedication and perseverance played a great role in skateboarding.
Skateboarding forever changes the way you see urban spaces. The 1960s architectural eyesores (碍眼的建筑) become a creative challenge which awaits the unusual exploration of a skater. With the streets as your playground, loyal friendships are formed. You wander like a wolf pack, hunting out new challenges and opportunities. And when you journey further into the unknown architectural skate spots around the globe, you know endless good times await. You’re a global conqueror aboard four wheels and seven layers of plywood (胶合板).
There are no short cuts in the sport. As a creative culture, skateboarding is big business for sure, but the ability to flow confidently on a skateboard is no easy thing to achieve. To succeed at anything worth hard work, you need patience and perseverance — skateboarding is no different.
I’m now 36, and, as I continue to age, my adventures as a skateboarder will go on. While tricks come and go for the most part, it’s the feeling of smoothly moving through time and space that inspires a skateboarder on. Skateboarding is an extension of play and of that, I shall never tire.

【推荐3】Like all big cities, Paris has a traffic problem: lots of cars, lots of traffic jams and lots of pollution from exhaust fumes. So the city began a project to improve the situation.
Under the Velib project (‘Velib’ comes from velo liberty, or ‘bicycle freedom’) people can take a bicycle, use it for as long as they want, and then leave it at the same or another bicycle station. The first half-hour on the bike is free, but if you don’t return it after 30 minutes, you have to pay. But it’s only €1 a day or €29 a year! The bicycles are heavy (25kg), and they are all gray and have baskets. There are about 20, 000 of them in the city, and around 1, 450 bicycle stations. So there are a lot more Velib stations than the 298 subway stations!
Paris is not the first city to have a project like this. But not everybody thinks it’s a great idea. One Parisian said, “These bicycles are only for short journeys. If people want to travel across the city, they won’t use a bicycle —they’ll still use their cars.”
A city spokesman said, “The bicycle project won’t solve all our traffic problems, of course. But it might help reduce air pollution. Traffic, together with factory fumes, is a big problem. There aren’t any simple answers to traffic problems and pollution in cities. But unless we do something now, there will be more traffic jams and temperatures will continue to rise, so the problems in our environment will get worse. The bikes might help people to lead a healthier life, too.”

【推荐1】Let’s face it—you’re attached to your phone. You use it to communicate, play games and surf the Internet. But there’s a great way to make your smartphone a life-enriching device without hurting your eyes. Check out the world of podcasts.
Think of podcasts as YouTube camels for listeners that you can download to your phone. What’s so exciting about that? Well you can find a lot of amazing shows! Whatever you find that catches your attention, one thing is sure—listening inspires the imagination. Because you can only listen to a show and not see it, you have to pay more attention. Therefore, your imagination has the potential to become stronger and more vivid as a result.
Podcasts allow you to experience the world from various angles. Take America’s NPR and Britain’s BBC, for example. Both have produced several podcasts. By listening to them, you can learn to appreciate cultural to linguistic distinctions. Choose what you like. In the end it’s your device—you get to decide who influences you!
So what’s out there? Lots! Since podcasts are created for very specific audiences, you’re sure to find one that interests you. Podcasts had been around for more than a decade, and one that really put podcasting in the spotlight is called Serial. It’s in the form of a story, broken up over several weeks, complete with cliffhangers. Or maybe you like listening to people discuss interesting topics. My personal favorite is White Horse Inn. If you’re a fan of informative speeches, subscribe to one of the many TED talks podcasts. There are several language-learning podcasts too, like ESLPod. The list goes on. If you’re not sure where to start, look up “top podcasts” and give one of their recommendations a try.
Whether you’re riding a bus, exercising, or just relaxing, put on some headphones and put your listening skills to the test. Download a podcast App, subscribe to a few and get listening. Or, better yet, if you have an idea for a podcast, why not produce one yourself!

【推荐2】In habitats across the planet, animals periodically drop everything to walk, fly or swim to a new place. Wildlife such as whales and geese learn migration paths by following their parents. Others, including small songbirds, gain the distance and direction of their migration within their genetic code. And some animals use a combination of genetics and culture to guide their migration.
Another group of migrators does not quite fit either model, and researchers have only recently started to figure out how they find their way. Take the Cory’s shearwater, an oceangoing sea bird that migrates over the Atlantic every year. The young do not migrate with their parents, so culture cannot explain their journeys. And the exact paths vary wildly from individual to individual, making genetics equally unlikely.
Cory’s shearwaters are long-lived, rarely producing young successfully before age nine. This leaves an opening for learning and practice to develop their migration patterns. Researchers call this the “exploration-refinement”, and until now it has been hypothetical (假设的) because of difficulties in tracking migratory animals’ movements.
But a team of researchers has done that by attaching small geolocators to more than 150 of the birds aged four to nine. They found that younger birds traveled longer distances, for longer periods, and had more diverse paths than older birds. “We finally have evidence of the ‘exploration-refinement’ for migratory birds,” says Letizia Campioni, who led the study. Younger Cory’s shearwaters are able to fly just as fast as the adults— but they do not, suggesting that the young do more exploring, which gradually fades as they mature and settle into a preferred course.
Although it may seem less efficient than other strategies, “exploration refinement could be beneficial to birds and other organisms (生物) in a rapidly changing world due to unpredictable man-made changes,” says Barbara Frei. “It might be safer to repeat a behavior that was recently successful than to rely on patterns that were perfected long ago but might no longer be safe.”

【推荐3】Earthquake forecasting is one of the most ancient skills known to mankind. From ancient Greece to the present day, countless scientists have tried to develop tools to predict earthquakes. Their attempts usually focused on searching for reliable evidences of coming quakes.
However, there are many reasons why predicting quakes is so hard. “We don’t understand some basic physics of earthquakes,” said Egill, a research professor at the California Institute of Technology. Scientists have also attempted to create mathematical models of movement, but precisely predicting would require great mapping and analysis of the Earth’s crust. Other challenges include a lack of data on the early warning signs, given that these warning signs are not yet entirely understood. Actually, real earthquake prediction is very similar to the diagnosis of potential human illnesses based on observing and analyzing each patient’s signs and symptoms. As it turns out, quake prediction is extremely difficult.
Many sources show that earthquake forecasting was a recognized science in ancient Greece. Ancient Greeks lived very close to nature and were able to detect unusual phenomena and forecast earthquakes. The first known forecast was made by Pherecydes of Syros about 2500 years ago: he made it as he scooped water from a well and noticed that usually very clean water had suddenly become muddy. Indeed, an earthquake occurred two days later, making Pherecydes famous. Nowadays, seismic and remote-sensing methods are considered to have the greatest potential in terms of solving the earthquake prediction problem.
Currently, Terra Seismic can identify a forthcoming earthquake with a high level of confidence. Generally, Terra Seismic does not predict a quake if the earthquake’s epicenter is located beyond a depth of 40 km. Fortunately, such quakes are almost always harmless, since quake’s energy reduces before reaching the Earth’s surface. “Scientists have tried every possible method to try to predict earthquakes,” Bruneau said. “Nobody has been able to crack it and make a believable prediction.”
