Fastest star in the galaxy

　　Recently, German astronomers discovered the fastest-moving star on record near the center of the Milky Way.

　　In general, it is difficult to find new stars near Sagittarius A*, the black hole at the center of the Milky Way, because the closer you get to the center, the denser the stars and the harder it is to identify them. This time astronomers identified five new stars there using the Very Large Telescope in Chile.

　　Among them is S 4714, whose elliptical orbit is only 12.6 times the distance from the Sun to the Earth at its closest point to the central black hole. It travels at nearly 24,000 kilometers per second, or 8 percent of the speed of light.

　　Looking at the sky from such a star should be very fascinating. The sky will be filled with bright stars. You can also see the massive black hole and the bright accretion disk formed by the material falling into it. In particular, you can also observe the strange time and space drag effect. General relativity predicts that when a celestial body moves at a fast speed, it will drag the surrounding space-time, creating a vortex-like structure, just like you stir the batter with a chopstick; and the light that would have traveled in a straight line, in such a space-time When propagating, it also takes a tortuous path.

Moroccan football team: "The most familiar stranger"

　　When I was still in college ten years ago, I led a sightseeing group of more than 30 Moroccan students. Before meeting them, my general impression of the Moroccans was that they are from North Africa but closer to the Arab world. They have religious beliefs, are used to worship, and are inextricably linked with France. 　　When I saw the real person, I realized that the North Africans in front of me were actually a group of children playing with each other and having fun in time. They were about the same age as me at the time. I have all kinds of nicknames and nicknames. During the process of taking them to Badaling, the Summer Palace and Houhai, two classmates and I, together with more than 30 Moroccan students, realized "cultural integration" and "world unity" in the small group to some extent. 　　During the World Cup in Qatar, I was surprised to find that the little-known Morocco team, which was eliminated in the group stage of the last World Cup, after miraculou...

Zeigarnik effect

　　As a freelancer, you have to fight procrastination every day. "I've made up my mind many times, but I just can't change it. Is it because I'm slow or slow?". In fact, many procrastinations are irrational. Many obstructions are imagined by myself. So distract, postpone, avoid confrontation. It's cool to procrastinate, and it's cool to procrastinate all the time, so I can't do it. Concentration is also related to physical strength. When the physical strength is exhausted, it is even more difficult to concentrate. You’ll tell yourself: I’m too tired to do this—okay, another perfect procrastination. 　　In 1927, Bruma Zeigarnik's senior research found that people are more likely to care about unfinished and interrupted work than completed work. This is the Zeigarnik effect. For example, we often don't care much about what we have got, but we will especially cherish what we have worked hard but haven't got. Therefore, the TV series will tell you...
