What jokes or obstacles do you have in the basic five subjects competition?

I was lucky enough to listen to a lecture by Mr. Shu Yousheng, and found that Mr. Shu's speech was very funny, so I extracted his interesting sentences as follows:

1. "What do you think of this problem? ... in fact, students who are good at physics are good at math, and students who are good at math are not necessarily good at physics. So we can easily see that these four points are * * * circles ... "

It seems that I chose a kinematics topic. If I remember correctly, the police caught the thief. )

2. "Non-inertial system has a wish"

(Ready to introduce inertial force)

3. "The math person doesn't agree. He says your EQ is too high." "At that time, the emotional intelligence was very high, and the result came out at once, which was easy to understand."

(Mathematically inaccurate derivation is given)

4. "Who should we admire? Admire the questioner. "

(Comment on a riddle he heard in a foreign taxi)

5. "This child has one characteristic: he likes boys. Oh, he is a boy."

(Evaluation by a proud disciple)

6. "Is the universe equation easy to solve? There is no solution. So let's look at the particle system. "

I have discussed some philosophical contents related to determinism before, and found that it is beside the point. )

7. "I see how those students can turn pens so flexibly. I fell when I turned around, so I envied them, and then I made up a topic. "

(still choose a topic)

8. "Now" (the first two words of a quiz), look at this.

Does the change of tone indicate that the difficulty may have increased? "

(same as above)

9. "How big is this order of magnitude? Let's assume that a person has been writing zeros all his life. Can he finish writing this number? " (Some calculations) "This man wrote more than 30 billion zeros, which is really amazing, and then he died. Then he gave it to his son. Oh, he has no son. "

10. "At that time, there was a very famous physicist. I forgot his name. "

1 1. "It is natural that these two security guards have not studied relativity."

(Relativistic train tunnel paradox)
