Deep Space Planet Leader

One week later.

Earth Era has unfolded a huge light sail, formally broke free from the gravity of the moon, and headed to the Jupiter Industrial Base.

The laser system of the moon base and the rays of light from the sun will provide continuous power for it.

For the small society inside, there is not much difference between spaceship being static or moving.

A vast "basic ability level test" will be staged in various regions.

The "Star University" and "Deep Space University" in spaceship have officially started enrolling students.

Of course, the current recruits are all graduate students, and only a very small number of undergraduates are enrolled. If some people really want to re-enter the university, it is also feasible.

"...have you all figured out what major you want to take the exam?"

"If anyone is good at the exam, he can formally be transferred from this low-level post, and he doesn't need to be with me Sweeping the floor. Getting together is fate. For the first classmate in our group, I will also give him a brand-name fountain pen brought from Earth!"

Wang Xin took out a bright Shining pen, said to a group of members.

The other 7 people have just graduated from college, that is, he is in his early thirties.

"Brother Wang, you must be eccentric. With Zhang Yuan here, you might as well give it to him directly!"

A girl yelled.

"Yeah, yeah."

Zhang Yuan is a little bit embarrassed. In fact, everyone is a schoolmaster, basically there is no such thing as a fool.

It's just that after a long period of struggle, he has evolved into a master of God, not only smart but also hardworking, which is beyond comparison by others.

He quickly turned off the topic: "Brother Wang, what about you, don't you plan to take the exam?"

"I have graduated for so many years, and I have forgotten all that knowledge. What exam to take."

Wang Xin said with a smile: "I will do some administrative work in the future. It doesn’t matter if I hibernate earlier. Anyway, my wife is here, and Earth has no worries. Every place needs talents, not just scientific research talents, right?"

Zhang Yuan nodded.

In fact, there are many expert scholars, all of whom take the spaceship to the family. Of course, their families are basically equally good.

"Which research do you want to do one by one?"

"Spaceship planting!"

"Spaceship environmental science!"

"Hey, me, being a programmer is enough..."

......

"Zhang Yuan, how about you?"

Zhang Yuan is a little confused. He actually likes mathematics, such as the "far Abelian geometry" studied by Professor Wang Zhong, or symplectic geometry, but these subjects are all Epic Grade sinkholes, the current spaceship Inside, there are no particularly strong pure mathematicians.

So after much deliberation, I can only engage in the larger direction of "space mechanics". There are several well-known professors in these directions, and they have even met and interviewed beforehand.

As we talked, the bell rang, and Zhang Yuan and everyone walked into the examination room.

The "basic ability level test" is an important basis for applying for graduate students. Although he has been selected by some professors, he still has to take the test to avoid being spoken out.

He has four exams to take. The first sect is "advanced mathematics", which is a basic course, and basically every candidate has to take the exam.

The remaining three subjects are informatics, basic algorithms, and political history.

"Please note that all candidates, the test item in this test room is advanced mathematics. The test time is three hours. Please turn off the communication equipment."

Said: "...There are too many people in spaceship now, and it’s a bit too much to support. Any cheating will be recorded and forced to hibernate."

Suddenly, all the candidates became nervous and sent out There was a sparse sound.

A few more candidates handed in their mobile phones.

The test paper has been issued.

Zhang Yuan glanced at the subject.

1. Set b=(√5-1)2, and define the number sequence an: when [b*n] is odd, an=1; when [b*n] is even, an =-1, [x] is the rounding function, ask whether Sn=∑an is bounded.

Hey, did you choose to fill in the blanks?
