A high-achieving student holding peking university Tsinghua diploma ran to the renmin university affiliated middle school to apply for a teacher, and after reading his thick resume, the principal asked meaningfully: "Our teacher's monthly salary is only 4,000 yuan, and we have to be busy from morning to night, are you sure you are willing to come?" Gao Caisheng was stunned, and the principal thought that he had played a retreat, but he did not expect that his words later made the principal completely change his mind.
Since he was a child, Li Yongle has been addicted to physical phenomena such as "small hole imaging", "rainbow formation", "refraction of light" and so on, always chasing the teacher to break the sand pot and ask the end. When he grew up, he became a veritable bully:
Accidentally, in the National Physics Olympiad, he won the first place in Jilin Province;
Accidentally, he was sent to the Physics Department of Tsinghua University, and then accidentally admitted to peking university graduate school.
Holding the golden resume of "Tsinghua Peking University", Li Yongle was originally a beloved fragrant feast, who ever thought, because of a mouth that was too "straight", the road to job hunting made him suffer a lot.
With the aura of a famous school, Li Yongle passed the barriers and came to Lehman Brothers, Citibank, Goldman Sachs and other famous companies, and the interviewer smiled and asked: "You are very good, but there is one last question, can you accept overtime?" ”
"No way! Work is about efficiency, I am willing to improve work efficiency, but do not want to work overtime to affect normal life. Besides, employees are people and not machines. ”
Although the interviewers were confused, although they were moved by Li Yongle's high diploma, they also had to "endure the pain of cutting love" and gently "invited Li Yongle out".
Li Yongle never dreamed that he would be rejected by many famous enterprises. Frustrated, he stayed at home for three days, and his father couldn't help but point out: "Your upright personality may be difficult to see the wind and steer in the workplace, so it is better to try to go to school and be a teacher who only pays attention to right and wrong." ”
Li Yongle woke up like a dream and came to the Beijing People's Congress Affiliated High School with a thick resume. The principal suppressed his excitement and tentatively asked: "You are a highly educated talent, but the teacher's salary is only 4,000 yuan, are you willing to come?" ”
Li Yongle said seriously: "I think young people can't take money too seriously, teaching and educating people is a very meaningful thing, and it can't be measured by money." This time, he "accidentally" became an "internet celebrity teacher".
I have to say that Li Yongle seems to be born to be a teacher's material, standing on the three-foot podium is like starting a personal show variety show. He explains the knowledge points and asks guided questions, interspersed with some anecdotes about scientists.
If other physics teachers explain the "pressure difference", they generally start from the concept first, and the "pressure difference" refers to the difference in air pressure on the indoor and outdoor surfaces of the window. When the air pressure on the outdoor surface is greater than the indoor surface, the pressure difference is set as positive; conversely, it is set as a negative value.
Students are naturally confused about this abstract concept. But Li Yongle took out a boiled egg, peeled off a corner of the egg, and then took a deep breath to hold the egg and blew it hard, resulting in a completely peeled egg. At this time, Li Yongle will throw out the knowledge points of the pressure difference, and the students will suddenly realize.
For example, when other teachers talk about parabolas, they may just draw dry pictures and then lead to the concept: in the plane, the trajectory of the point to the point at which the distance between the fixed point and the fixed line is equal is called the parabola. But Li Yongle tells the love story of Descartes and the princess, which leads to an equation: r = a (1-sine), also known as the "heart parabola".
Under his description, the students nibbled on the usual obscure physics. The students affectionately called him "Yongle The Great" and "Poor Life Savior"!
In the past few years, Li Yongle "accidentally" sent more than 200 students to Tsinghua Peking University, and also brought out dozens of international and domestic Olympiad gold medalists. This year's physics competition gold medal winners Zhang Zhelun and Sun Xiangkai, two classmates, are the proud protégés he brought out.
But despite bringing out a lot of high-achieving students, Li Yongle is still worried, especially after a trip to Gansu, he thinks he must make some changes!
When Li Yongle went to Gansu to teach, he found that the teaching resources there were poor, there was no laboratory at all, the students knew little about physics, and the science results were also very poor. Li Yongle was sad to see it, because he also came from the countryside.
Therefore, Li Yongle broke the obsession of "no overtime", took the initiative to take out 4-6 hours a day, recorded many interesting popular science videos, so that physical knowledge was cloaked in grounded gas, and students could quickly understand and absorb obscure knowledge points.
A popular science video of "what is going on in a leap year" became popular overnight, and even CCTV couldn't help but like and forward him like crazy.
Li Yongle is simply a "man who grows up on hot spots", so that his aunt can fall in love with "mathematics, physics and chemistry", and every social issue is followed by his popular science:
It takes a few seconds to escape from a 40-meter machete;
Why retail investors in the stock market are prone to losses;
Why don't the Winter Olympic jumpers fall from a height and get injured?
All the metaphysical problems are interesting physics problems in the pen of teacher Li Yongle.
Many parents hope that Li Yongle will compile a set of physics enlightenment books suitable for children to read, Li Yongle spent 3 years to carefully compile a set of "Li Yongle Teacher To Children About Physics" 42 volumes, this set of books covers 20 major themes layer by layer, both from shallow to deep, but also divergent thinking, no formula, only fun and popular science.
Li Yongle continued his consistent style, the word "interest" throughout the end, from the beginning to the end is trying to tell children that physics is not only very interesting, but also very useful, once listed, it sold 20 million copies, the craziest time is even difficult to find a book!
"Peking University Tsinghua is far away, the ladder is very close, and Teacher Li is the ladder."
"There is only one Li Yongle between me and Peking University Tsinghua."
CCTV host Ju Ping highly recommends this set of books, and said that it satisfies children's curiosity, develops good habits of research, and enlightens children for a better future.
Nowadays, the era of off-campus tuition is coming to an end, the era of big physics has arrived, and those who get physics win the world! This set of 128 books was rated by CCTV as "one of the best books for primary and secondary school students"! The new semester has arrived, in order to let the child not lose at the starting line, smart parents hurry up to give their children a set of it!
