An astronomy enthusiast, an astronomical knowledge

Absolutely, as long as you have the knowledge of it.

I studied materials science in college, but many of my classmates did not take the materials study exam, but also took the business and politics exams.

It doesn't matter at all.

Now they are not the same as they are studying well?

It's hard to say specifically, but if you're doing theory, it's best to have a good foundation in physics and mathematics. Because I have a junior in my laboratory who is doing astrophysics, he is in the physics department as an undergraduate.

Yes, but you need to have a good foundation in physics and mathematics. At present, Nanjing University, Peking University, Beijing Normal University, University of Science and Technology of China and Tsinghua University in China have astronomy graduate programs. In addition, the observatories also recruit graduate students.

Absolutely, I wish you all the best!

If you really want to take the test.

It is recommended to take the Shanghai Astronomical Observatory of the Chinese Academy of Sciences, which has close cooperation with Max Planck in Germany, and it is easy for students to go to Max Planck, which is conducive to later development.

One of my classmates had an undergraduate degree in English, and went to a first-class university to do theoretical physics. Cow, right? Don't be afraid of difficult exams, if you work hard, you will have no problem.

Finally, I want to say: now that inflation is serious, the domestic scientific research environment is not very good, and most of the professorships have been filled by people in the prime of life, it is not easy to support the family through scientific research. Please choose your career carefully.

Absolutely, as long as you have the knowledge of it.

Believe in yourself. I can do it.

Proxima Centauri, the closest star to Earth, is 4.24 light-years away.

The circumference of the Earth's equator is about 40,076.5938 kilometers.

The average distance of the Moon from the Earth is 38.40 thousand kilometers.

It takes 27 days, 5 hours, 5 minutes and 43 seconds for the Moon to orbit the Earth.

The Earth's revolution around the Sun is one year, which takes 365 days, 5 hours, 48 minutes and 46 seconds.

The rotation of the Earth is one day. The time of the "day" is not 24 hours, but 23 hours and 56 minutes.

The cycle of the moon's circle is 29 days, 12 hours, 14 minutes and 3 seconds, which is the lunar month.

The galaxy in which the solar system is located is called the Milky Way. The Milky Way is like a giant pie, about 80,000 light-years wide and about 10,000 light-years thick in the center, with a total number of more than 1,000 stars.

Is this okay with the landlord?

Untitled: This is profound.
