After watching 22 episodes in one go, it seems to be still being updated.

1. Most of them don’t understand it. To read this kind of popular science is still curious to some extent.

2. The reason for not understanding is mainly counter-intuitive (more counter-intuitive than the theory of relativity), and daily experience is completely useless. This is very different from social science popularization.

3. The study of elementary particles seems very interesting, and the study of such a grand problem of the origin of the universe seems to finally return to the most microscopic level of elementary particles.

4. In the study of theoretical physics, mathematics is the killer. I feel that several major unifications were completed by mathematically talented people standing on the basis of their predecessors. Moreover, the research paradigm has also changed from “experimental observation -> finding explanations” to “calculation + prediction -> experimental verification”.

5. The paradigm shift should be that the experimental methods cannot keep up with the research scale of quantum (including the universe) physics.

6. In the first half of the 20th century, the stars were shining brightly. ——At this time, there were two world wars in Eurasia, and the United States was alone overseas, and it was really the national fortune.

It is often said that there will be flooding after a severe drought, but the truth is so simple: the water has evaporated to the sky, and sooner or later it will come down.

And because of the severe drought, the land adhesion is very poor, and the heavy rainfall is easily accompanied by flash floods and mudslides.
