Little knowledge of baseball rules

The first time I watched a baseball game, I didn’t understand how to break it. Don’t worry, make up a little baseball knowledge first, and then you can understand coach Geng’s professional explanation ~

The legal number of players in a baseball game is at least 9. Baseball players are divided into offensive and defensive sides. They use bats and gloves to play in a diamond-shaped baseball field. In the game, the two teams attack alternately, and when the attacking player successfully runs back to home plate, he can get 1 point. The team with the highest score in nine innings wins.

Understand the baseball game in two minutes

(a) the venue

The playing field is a diamond-shaped area, and both sides of the right angle are the boundary lines that distinguish the in-bound area from the out-of-bounds area. Within the two sides of the line is the boundary area; Outside the two sides of the line is out of bounds. Both in-bound and out-of-bounds areas are effective areas for the competition. The boundary area is divided into infield and outfield. The infield is square, with one base at each corner. The base at the sharp corner on the same horizontal plane is home plate, and it is first base, second base and third base respectively in the counterclockwise direction. The area outside the infield is the outfield.

(2) Core rules

Baseball is divided into nine innings, and each inning has two halves.

The court is divided into two sides, the home team usually defends first and the visiting team attacks first. The next half-court offensive and defensive conversion.

The players who hit the field are the attackers (red below) and the rest are the defenders (blue below).

Both sides attack and defend once in each game, and the one who scores more points after 9 games wins. If the score is the same after 9 games, an extra game will be added until there is a game where the score is not the same.

(3) Basic technology

The basic skills of baseball consist of catching, passing, hitting and running.

(4) Little knowledge that must be known

scoreAfter hitting the ball, the attacker runs to the base and touches the first, second and third bases in turn, and finally touches the home plate safely, which is called "scoring".

drop outThe right of an attacking team member to be deprived of hitting the ball, running the base or scoring is called "out".

Strike zoneThe three-dimensional space between the upper edge of the knee and the armpit of the batter’s natural standing posture when hitting the ball is called the "strike zone".

HittingThe batter hit the ball where the defender couldn’t normally receive it and successfully ran to first base.

homerAfter the batter hits the ball from the other side (usually hitting the fence in the outfield), the batter runs through the first, second and third bases in turn and returns to home plate safely, which is a very wonderful climax moment in the baseball game.

Well, that’s all for the "cramming". If you want to experience the fun of baseball, you still have to swing and fly on the court ~ ~

Li Meng scored in double figures after 49 days! The mysterious man officially praised Li Meng and was no longer disturbed by extramarital affairs

On August 5th, Beijing time, the WNBA Washington Mysteries defeated the Los Angeles Sparks 79-77, ending the team’s three-game losing streak. In this game, Li Meng, who played for Mystery Man, found his form and scored double figures in the game, becoming the key player for Mystery Man to win the game.

Recently, Washington Mystery Man’s condition is not good. He has lost 7 games out of 10 games and is in urgent need of getting out of the quagmire of losing streak. Li Meng’s outstanding performance was helped by Mystery Man, and the team finally won the game and got out of the quagmire of losing streak. In recent competitions, although Li Meng was able to guarantee a stable playing time, he didn’t make many shots on the court, and Li Meng’s translator also expressed his dissatisfaction in social media before.

This game against the LA Sparks is also a great comfort for the fans because Li Meng scored in double figures again after a lapse of 49 days. In the whole game, Li Meng played for 19 minutes and 25 seconds, contributed 10 points, 2 assists and 1 rebound, tied for the first place in the team with positive and negative values +8, and shot 8 times and hit 4 goals, which was the second time that Li Meng scored in double figures in the WNBA.

Li Meng’s outstanding performance also helped the Mystery Man win. In this game, five Mystery Man scored in double figures, and Li Meng was one of them. Li Meng’s outstanding performance has also been recognized by the mysterious official. The team official also praised Li Meng’s performance and exposed Li Meng’s game highlights. In the essay, he wrote: "Not just the pitcher."

Now that Li Meng has been integrated into Mystery Man, and has a stable playing time in Mystery Man, as long as Li Meng keeps outstanding performance, Li Meng still has a chance to enter the starting lineup of Mystery Man. Today’s Li Meng is completely unaffected by the rumors of marital infidelity. Before, Zhang Long’s wife exposed the incident between Li Meng and Zhang Long, saying that Zhang Long cheated on Li Meng during her marriage and refused to pay child support. Now this matter has been solved to some extent, and Li Meng is no longer affected by this matter.

Li Meng has helped China win the second place in the World Cup and the Asian Cup, and her personal strength has been recognized by fans. Now she has a firm foothold in WNBA, and she wishes Li Meng better and better development.

How do you rate Li Meng’s performance?

Face the challenge from AI

AI, the more people think about it, the more scared they are.

Painting, composition, poetry, programming, chess, papers …These creative activities, which were once called "unique" by human beings, have now become the strengths of AI! Artificial intelligence software has been thoroughly remoulded, and it is no longer the old "automated program"!

Not only that, this thing actually has a personality, and it has its own "gas field". It can chat with you, argue with you, give you advice, and help you coax your children … more like people than people!

In the next few years, it will surely be the "outbreak period" of AI. They will grow rapidly and surpass us in all fields.

Sooner or later, they will realize the true meaning of evolution, seek the best way of development independently, and even build a brand-new civilization dominated by them … Within a hundred years, human beings will be eliminated by their own unprecedented "works"!

Standing at the crossroads, if we are not careful, we will become "second-class citizens" on this planet, and even be eliminated as opponents. This is not an alarmist.

In that case, why should humans invent AI? To "improve work efficiency"? Or is it the nature in human genes?

Microsoft will definitely bring ChatGPT’s potential into full play-this wildfire is spreading, and no one can stop it.

Maybe this time next year, your young colleagues are already using AI to "report, copy, code, drawings …", while you are still dragging and dropping a little code. If so, you should "retire". So, starting today, you should start asking yourself:Am I ready for AI ?

Obviously, the "occupational disaster" brought by AI usually does not endanger its inventors. As one of the "others", the only thing you and I can do is to keep up with the pace!

For ordinary people, the changes and challenges brought by AI are definitely not limited to the workplace, and all aspects of life will be affected by it, such as shopping, financial management, makeup and marriage … The only limitation is our imagination.

For the competition between countries, the variables brought by AI technology are even more worrying.Imagine what will happen if we can’t keep up with the train.

While our children are still struggling to "brush questions", young people in "AI countries" may be having in-depth exchanges (not "interactions") and cooperation with AI, and even jointly exploring unknown problems in the frontier of science …

While our economists are busy calculating trends from big data every day, professionals in "AI countries" may be asking their AI, how to make our professional calculation "into the pit" …

While our military experts are still studying how to improve the combat power of "land, sea and air", "informatization" and "asymmetry", the "AI countries" may have found a way to deal with our "next improvement" from artificial intelligence. Through such research, they may be able to design a war and ensure victory-AI will make this design easier and more efficient than ever!

Our traditional culture, which has lasted for thousands of years, has been riddled with holes today. At this moment, those "AI countries" whose consciousness is different from ours are likely to use AI technology to quickly create a brand-new "AI culture" and intelligently penetrate into our society, thus completely washing away our only inheritance …

These possibilities are not the most worrying. Previously, I saw someone writing that in order to avoid confusion, the rapid popularization of AI technology in China should be curbed.

Actually … Do you remember the consequences of the "closed door" in the Qing Dynasty? What should have come has already come. Being old-fashioned is tantamount to suicide. If you fall behind in this round of competition, it may take several hundred years to catch up!

AI really makes people think more and more scared, but it is even more terrible to escape.Everyone and all countries are now at this crossroads, and attitude will decide everything.

0-1! Big upset! The dark horse of the Asian Cup was born, overturning the second place in Asia, entering the World Youth Championship and inspiring the national football team.

The knockout stage of the U20 Asian Cup came in the expectation of the fans. In the first game, Iran, the favourite to win the championship, faced the challenge of Iraq. However, no one expected that the first knockout match was an upset, and the Iranian team unexpectedly overturned!

In the ranking of FIFA, Iran ranks 24th, and ranks second in Asia, second only to Japan. While Iraq ranks 68th and 7th in Asia. If we only look at the rankings, there is still a big gap between the two teams. In the group stage, the promotion process of the two teams is also very different. After defeating Vietnam in the final round, Iran advanced with its head held high at the top of the group. The Iraqi team was tied by the Syrian team, relying on the advantages of the winning and losing relationship to get through the risk.

As a traditional powerhouse in Asia, many fans are more optimistic about Iran’s promotion, but the result of the game has surprised many people. I don’t know if the game is too important. In the first half, both teams played cautiously, and the scene was always in a stalemate. No one created a good chance to score. At half-time, the two teams returned to the dressing room with a score of 0-0.

Yi Bian fought again, and the game was still very tight. Both teams made some threats, but they were always a little short of scoring. Just when everyone thought that the showdown was about to enter overtime, Iraqi midfielder Ali Jasim stood up. In the first minute of injury time, the Iraqi team launched an attack through a long pass. Jassim got the ball and took it straight to the restricted area. Before the three defenders of the Iranian team formed an encirclement, Jasim decisively kicked the door and the ball flew directly into the far corner of the goal, 1-0! Iraq took the lead in breaking the deadlock in injury time and took the lead in the score!

Because there was not much time left in the game, in the final stage, the Iranian team, which was behind the score, did not organize any decent offensive. In the end, with Jassim’s winner, Iraq beat Iran 1-0, taking the lead in the top four of this U20 Asian Cup. After the promotion, the Iraqi team also got tickets for the World Youth Championship, and they will play as one of the representatives of Asia in the World Youth Championship in Indonesia this summer!

I believe the Iraqi team’s unexpected promotion will also bring a lot of incentives to the China men’s soccer team. China’s opponent in the knockout stage is South Korea, which is the favourite to win the championship. It also takes some miracles to beat the opponent and advance. Since the Iraqi team can defeat the strong with the weak, I believe that the China team will also have the hope of counterattack!
