I did some popular science videos and posted them online.
Most of the videos are unattended and few viewers.
But there are also a very small number of videos, probably due to a bug in the algorithm of a certain sound platform, which has been pushed to many people.
Why is it a bug? Because I saw a lot of comments that wrote: "I do x, why did I brush this?" (X values: beauty, food, cosplay, ghost animals, etc.).
Of course, there are also pushes on the right people, because some of the comments are "come and learn@xxx @yyy @zzz"
But that's about it, just throwing the bricks out and someone noticed.
It wasn't until the other day that the bricks I threw out finally led to jade.
Popular science is to let everyone gain something in a relaxed and pleasant way, because few people are willing to look at serious professional knowledge, which I deeply understand. It is said that Qian Zhongshu was inspired to read the books in the library, and I also tried it, borrowed a copy of the "Mechanical Design Manual", and felt that it would be good to finish this book in four years. Classmates said, that is different, this is an engineering book, to see the liberal arts class.
I borrowed a book in this subject, the Diamond Sutra, it is not easy to read, the original text is a dozen words, the translation and interpretation have several pages, a total of more than 5,000 words of the Diamond Sutra, I spent more than 10 days to read. It's so easy to read a book from the library!
Therefore, it is necessary to have some popular science things come out, so that non-professional people do not have to chew, and easily look at it. Of course, it would be nice if it could still provoke people to think.
The video "Collision Simulation of Two Planets" does just that, and in the video I released, this is the first video to achieve the effect of "introducing jade".
For example, many people in the comment section questioned that two planets could not collide together, because there was a Roche limit, and it would be torn apart before the collision.
This kind of thinking is very good, and it will definitely be rewarding after thinking about it. We often encounter situations like this in school classrooms:
Textbooks and teachers tell you: Small a is a kind of big A, and a will become b under condition x
Then there will be a thinking question in the textbook (maybe the font will be very small): Will all As become B under condition x?
Don't underestimate this little problem, as it may appear on the exam paper.
I believe that if the people who brushed my video encountered such a judgment question: two celestial bodies collide, will they be torn apart before colliding?
He wouldn't be wrong.
In addition, there have been some humorous fishing comments that can trigger more audiences to think, such as:
Where did the gravitational pull of the planet shatter? (I thought it wasn't fishing before, but now it seems to be)
Where does a planet that doesn't rotate get gravity?
Simulation, if that's the case, I've eaten the universe.
There will be no direct collision, it will definitely circle in a circle first, and it will be hit after a long time.
This collision process lasts 10 million light-years.
These comments have received a lot of likes, but also attracted a lot of replies, the discussion is very warm, and those who participate in the discussion will be rewarded.
So, after causing people to think about it, my video itself is no longer important, the comment area is more exciting than the video, and its task has been completed.
Recently, the recommendation of netizens has also changed from "watching this video @xxx @yyy @zzz" to this:
"Come and see the review @xxx @yyy @zzz"
