The best thing in the world is that when I like you, you like me at the same time.
At first sight, she was a test taker and he was an inspector. She was arrested by him due to a failed cheating attempted.
When they met again, she was the class repre...
"Mu laoshi said that the upper and lower surfaces of the wings of an airplane are shaped differently. The upper surface is a curved aerodynamic surface, so the distance is long and the airflow has to travel a longer distance. at the same time, so the velocity is faster, while the bottom surface is flat surface and the flow velocity is lower. According to Bernoulli's law you just mentioned, to higher is the velocity, to lower is the pressure. So, planes use this pressure difference to fly. " Peng Yu explained very proud of himself.

It took me a long time to realize that the pressure from above was less than the pressure from below, which made it fly.
Liu Qi didn't get angry at Peng Yu even though he was mocking him. After hearing Peng Yu's words, he began to ponder and after a while, he showed a shocked expression, "It turns out that is so. Good to know."
Hearing Liu Qi's praise of him, Peng Yu puffed up with pride and said triumphantly, "These kinds of things are pure trivia."
"However, Master Peng", I deliberately decided to make things difficult for him, "I don't understand anything."
"What?"
"Have you seen those American fighter jets on TV?"
"Yes," Peng Yu agreed.
"According to you, when the plane turns," I made a turning gesture with my hand, "its wings will turn upside down, so why doesn't it fall off?"
"This ..." Peng Yu scratched his head thoughtfully, "I didn't ask Master Mu about that."
This is a tie.
On the way back, I told him, "You can't use other people's strengths to belittle him. Liu Qi also has his own strengths. The robot developed by his team participated in the robot ball game last year and entered the national final. They all have their strengths. If you asked Master Mu to build a robot, he would definitely perplex him. "
Peng Yu turned his head, pouted, and said, "But I like Master Mu better. You and Liu Qi are alike, just as Master Mu and I complement each other." After chatting, he was not happy.
"You are very judgmental," I joked.
"Xue laoshi, it's irrational."
"Why am I irrational?"
"You asked me to come to be a mediator between you, specifically to drive away Liu Qi."
I blinked, but I was being fair.
"I can't take it anymore. Now you say I'm bullying him out of sheer pleasure. You don't know what you want. I help you, but you go out and defend him, you say you're not irrational?" He said feeling aggrieved.
I was stunned, he was right, I patted his head apologetically.
He kept ignoring me.
So I said, "Okay, don't be mad. Next time I invite you to KFC as an apology."
