    Scientists have discovered a "monster black hole" so massive that, in theory, it shouldn't exist.

    It's a stellar black hole—the type that forms after stars die, collapse, and explode. Researchers had previously believed that the size limit was no more than 20 times the mass of our sun because 8S these stars die, they lose most of their mass through explosions that expel matter and gas swept away by stellar winds

    This theory has now been toppled by LB-1, the newly discovered black hole. Located about 15.000 light years away, it has a mass 70 times greater than our sun, according to a press release from the Chinese Academy of Sciences.

    The findings were published by Chinese researchers in the journal Nature on Wednesday.

    "Black boles of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution," said Liu Jifeng, head of the team that made the discovery. "LB-1 is twice as massive as what we thought possible. Now theorists will have to take up the challenge of explaining its formation."

    Scientists are now scratching their heads at how LB-1 got so huge.

    The Chinese team has proposed a number of theories. LB-1' sheer size suggests that it "was not formed from the collapse of only one star," the study said— instead, it could potentially be two smaller black holes orbiting each other.

    Another possibility is that it formed from "fallback supermova." This is when a supernoma—the last stage of an exploding star—ejects material during the explosion, which then falls back into the supernova, creating a black hole.

    This fallback formation is theoretically possible but scientists have never been able to prove or observe it. If this is how LB-1 formed, then we may have "direct evidence for this process" for the first time, the study said.

    There are several types of black holes and stellar black holes like LB-1 are on the smaller side, according to NASA. Supermassive black holes are much bigger—they can be billions of times the mass of our sun,

    Scientists believe supermassive black holes may be connected to the formation of galaxies, as they often exist at the center of the mass star stems but it is still not clear exactly how, or which form first.

    What is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry, geology, engineering, medicine or any other science?

    We all know that science plays an important role in our societies. However, many people believe that our progress depends on two different aspects of science. The first aspect is the application of the machines, products and systems of knowledge that scientists and technologists develop. The second is the application of the special methods of thought and action that scientists use in their work.

    What are these special methods of thinking and acting? First of all, it seems that a successful scientist is curious - he wants to find out how and why the universe works. He usually pays attention to problems which he notices have no satisfying explanation, and looks for relationships even if the data available seem to be unconnected. Moreover, he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves.

    He is a good observer, accurate, patient and objective and uses the facts he observes to the fullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum(光谱).

    He does not accept statements which are not based on the most complete evidence available. He rejects authority as the only basis for truth. Scientists always check statements and make experiments carefully and objectively.

    Furthermore, he does not readily accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation.

    Lastly, he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete. Furthermore, he needs imagination if he wants to guess how processes work and how events take place.

    These seem to be some of the ways in which a successful scientist or technologist thinks and acts.

    When Wu Jia, then aged 23, returned from Canada to work for her father's Hangzhou-based Zoland Animation (动画) in 2007, she found Chinese animation productions were just-so-so. Back then, Chinese animation shown at overseas events, received a poor response.

    But things soon changed following a boom in China's movie and television industries. By 2011, China developed into one of the world's largest animation producers, with animation and cartoon products reaching a record of 260,000 minutes.

    However, that figure has witnessed a fall in recent years. The latest statistics show that China made only 244 animated productions totaling 83,600 minutes in 2017. But Wu says: “Chinese animators are changing from quantity to quality and Chinese animators are now producing more quality works” at the 14th China International Cartoon & Animation Festival.

    Wu, now the chairman of Zoland Animation, is among those who are part of China's rapidly growing animation industry. She says the company has so far displayed more than 8,000 hours of animated content to 93 countries and regions, including the United States, United Kingdom, France, South Korea and Russia.

    Magic Eye, one of Zoland's most popular animated works, which was sold to just Singapore in 2006, is now reaching the screens of nearly 80 countries and regions worldwide. The 500-episode animated series about an alien boy's adventures on Earth also has a sequel (续集) series Magic Eye is Back, which has 104 episodes. Thanks to Magic Eye's popularity, the sequel quickly arouses interest in overseas markets and is being displayed in 38 countries and regions.

    Speaking about how to succeed abroad, Wu says: “First, the works should be good. And, you need an experienced team who knows international markets.”

    There are numerous amusement parks all over the world. A famous magazine, Amusement Today, does a survey among park lovers every year both in the US and overseas, based on which, “Top 5 List of the Best Amusement Parks in the World” has come out as follows:

    Disneyland, California

    Disneyland is a theme park in Anaheim, California, the US. More than 515 million guests have traveled to this American landmark from around the world since the park first opened to guests on July 17, 1955. The park consists of many world-famous sections, such as Main Street, Adventure Land, New Orleans Square, and so on.

    Magic Kingdom, Disney World, Florida

    Magic Kingdom is a theme park within the Walt Disney World Resort in Lake Buena Vista, Florida, near Orlando opened on October 1, 1971. It is the most famous theme park in Florida. The park's design and attractions don't make much difference from Disneyland Park in Anaheim.

    EPCOT, Disney World, Florida

    EPCOT is the second theme park built at the Walt Disney World Resort near Orlando, Florida. The park opened on October 1, 1982, and was named EPCOT Center from 1982 to 1993. It was the largest Disney theme park in the world until 1998, when Disney's Animal Kingdom opened.

    Disney-MGM Studios, Florida

    MGM's streets are the home for some great movie-themed attractions with a history of less than 30 years. With the addition of the Twilight Zone Tower of Terror and the Rock and

    Roller Coaster, the park is now home to Disney World's most thrilling rides.

    Universal Studios, Florida

    Go behind the scenes, beyond the screen and jump right into the action of your favorite movies at Universal Studios, the number one movie and TV theme park in the world.

    In 2016, designer Liz Ciokajlo received a task from the Museum of Modern Art (Moma) in New York: revisit the Moon Boot, a fluffy-looking snowshoe inspired by the footwear used by the Apollo astronauts.

    Launched in 1972 at the height of the lunar missions, the Moon Boot is an icon of the 20th Century's “plastic age” and the museum administrators wanted a new take on it.

    Ciokajlo set out to reimagine it. She knew only a biomaterial would work in a “post-plastic age”, but the designer also wanted a new destination to inspire it. Our generation's space travel obsession is not the Moon, she thought, but the red planet Mars. And Mars allows you to really think outside of the box.

    The task led her to an amazing biomaterial that had already attracted the attention of engineers innovating m building materials and of top space agencies like NASA and ESA. Her final design, a tall, female, rough-looking boot, can be made on board a spaceship with almost only human sweat and a few fungus spores (真菌孢子), ideal for a seven-month trip to Mars with limited check-in luggage.

    This magic biomaterial is mycelium (菌丝体), the vegetative part of the fungus It looks like amass of white thread-like structures, each called hyphae. Collectively, these threads are called mycelium and are the largest part of the fungus.

    Mycelium has amazing properties. It is a great recycler, as it feeds off a substrate to create more material, and has the potential of almost limitless growth in the right conditions. It can endure more pressure than conventional concrete without breaking. It is a known insulator and fire-retardant and could even provide radiation protection on space missions.

    On Earth it's currently used to create ceiling panels, leather, packaging materials and building materials, but in outer space it stands out for its architectural potential, says artist and engineer Maurizio Montalti, who has teamed up with Ciokajlo.

    For her revisited boot, Ciokajlo wanted to use the human body as the source for some of the building materials and decided to employ sweat. Reusing sweat is not entirely new in space exploration but a novelty approach for footwear. She thinks it might make astronauts feel closer to home during the long journey to Mars.

    The design is still hypothetical, because the real boot submitted for Moma and currently in display at the London Design Museum did use mycelium but not human sweat, as their deadline was too tight, but the science checks out.

Following the old saying of "early to bed and early to rise" I used to go to bed at 10 pm and get up early at 6 am to get ready for school. But that day, as it was cloudy, I continued to sleep for long, thinking it to be the early hours of the day.

Suddenly, I heard a loud voice which startled me up and made me sit upright. It was my mother's voice who was knocking and shouting, "Get up honey. It's 6:45 am already! You are getting late for school!" As it was a cloudy day, I hadn't realized that it was almost 7 and continued dozing for long!

But thank fully that day our pick-up person who generally used to come at 6:50 am got late due to the showers and arrived just in the nick of time when I was ready. By the time we reached school it was a quarter to eight and the drizzle from previous night had finally stopped. I entered the classroom fearing the teacher's anger, but saw only a few students had made it to school. Therefore, the principal declared a holiday. "Hurray!" We all cheered in a chorus at the unexpected holiday and decided to walk back home.

    As it had been continuously drizzling since the previous night there was water all over the place and the roads were impassable. Just then, at a distance my sister and I saw little kids playing in knee-deep water in the streets which touched the play button in us. We quickly approached them and merrily jumped and hopped in the pool of water with them. With shoes in our hands we continued parading on the muddy streets. We were thrilled and our hearts were filled with joy at the sight of the green and fresh leaves on the trees; the frogs drew our attention as we tried to catch butterflies.

    We finally reached home busily playing and laughing with mud-spattered uniforms and shoes. We hurriedly changed our outfits, washed up and sat watching TV with a bowl of hot soup! No doubt, I thoroughly enjoyed this day and secretly prayed for many such days in the future! To this day when it pours, the memories of that eventful rainy day bring a smile on my face!

    Rock climbing is not just for grown-ups. Your children can also enjoy this fun-filled activity as well as getting its advantages. Aside from its heart-health benefit, it is also known to increase their self-confidence and esteem(尊重). While it may not be an impromptu(即兴的) activity like running or biking, there are many climbing walls that are now available, especially with the development of fitness centers and camps.

    The great thing about having your kids join these activities is that it follows up on their natural quality. As you know, children are natural climbers. You can see them going up on trees or climbing tall ladders. With rock climbing, you can satisfy their urges to be a climber.

    What's more, it is fairly easy for the kids compared with adults. With a high strength-to-weight rate, they have less body weight to pull up, and they are more flexible(灵活的).

    It is also a low-impact workout that tests your children's endurance(耐性). It's easy on their joints(关节) as they burn energy during their ascent. In addition, climbing walls are like giant puzzles begging to be solved. Not only does it test the physical aspects of your children's development, but it also wakes their mental abilities.

    This exercise also helps develop your children's essential strength and flexibility. Kids are challenged physically as they pull, lift, stretch, and twist their way up. This activity also develops their eye-hand coordination(协调) as they perform their climb.

    Almost anyone can do it although it may vary in skill level, namely beginner, intermediate, or advanced. But despite its reputation as an extreme sport, children can do this. One does not need to be super-fit to join a rock climbing class. However, good technique is more necessary than strength when doing this sport.
