How did humans move to Mars en masse?
How do we deal with alien visits......
recently
77-year-old Peking University professor Jiao Weixin
Became popular on the Internet
Jiao Weixin is at the School of Earth and Space Sciences at Peking University
Taught books for forty years
At the same time, it is also a basic course for geophysics
Compiler of teaching materials
before
Every time Jiao Weixin goes to class
There were people at the desks and at the door of the classroom
Because it's too popular
The Peking University Student Union also made a special offer for him
Organized a series of lectures "Lao Jiao talks to you about aerospace"
After his retirement in 2011
Jiao Weixin joined
Chinese Academy of Sciences Old Scientists Science Lecture Group
Every year for different ages across the country
Primary and secondary school students with different knowledge backgrounds
Nearly 100 popular science lectures
Encounter "pseudoscience" on the Internet
Jiao Weixin will be very angry
"This is complete nonsense
But I don't criticize people directly
I'm just going to keep doing science."
In the short video released by Jiao Weixin
He talks about the energy released by gamma rays
Space junk all over Earth's orbit
It also talks about more than 300 facial expressions of cats
Even, walk on the bottom of the sea like an alien Siren
……
And these more than 1,400 short videos of popular science
All from Jiao Weixin's own creation
"Cardboard Mobile Phone Recording Method"
He was with his wife
Stick the content of the lecture on the cardboard
Then dig a hole in the middle of the cardboard
Leave space for your phone to record
That's it
Jiao Weixin persisted for 3 years
Although "sometimes it's quite strenuous"
But Jiao Weixin still enjoys it
The resulting video is vivid and intuitive
It is incomparable with other forms of popular science
When I used to teach at Peking University
Jiao Weixin has a nickname given by students
- "Space Guide"
Nowadays, Jiao Weixin, who is doing Internet science popularization
is no longer just a space tour guide for Peking University people
His account is like a ship
A spaceship with no thresholds and no barriers
I carry more people
Travel to a world beyond Earth
As he said
"Scientists are people who are ahead of human development
Only scientists are willing to lead people into the depths of the universe
Only then can the human imagination gradually become reality
Humanity can keep moving forward."
May more people be able to
Develop an interest in "lifelong Xi".
Desire true knowledge, gain true knowledge
