I Made Scientific Magic

Early the next morning, a group of wizard apprentices stepped into the examination room with apprehension. After getting their own examination papers, they quickly counted with frowns.

Pierce didn't dare to delay, and turned his gaze to the first question.

[A and B are walking towards each other from two places at the same time. After four hours, they meet at a distance of 5 kilometers from the center point. It is known that A is faster than B. How many kilometers is A faster than B in an hour? 】

Pierce frowned all of a sudden. This should be an Olympiad problem, seeking the unknown, but there were not many conditions given. After thinking for a long time, he finally got the idea to solve the problem, and began to draw a line diagram.

On the other side of the examination room, several wizards in charge of the examination were also looking at the examination papers in their hands.

Fulla and the others were very interested in this graduation exam of the Iyeta School, so they reported themselves to be brave enough to come over to supervise the students, and at the same time became a little bit interested in doing the questions.

Originally, Fulla thought that these questions were prepared for apprentices, and it was not easy for her as a formal wizard, but after reading a few questions in a row, she was immediately dumbfounded.

"Does the Iyeta Academy teach these on weekdays?" A wizard asked confusedly, he thought the content of the exam would be knowledge about elements, herbs, alchemy, and shaping.

"Not bad!" Lin En nodded, looked at Fulla and the others, and said. "Generally speaking, there are three subjects: Mathematical Olympiad, Chemistry, and Physics... Biology may be added in the future."

"But what's the use of learning these things? Why don't you learn a few more spells if you have time..." Fulla curled her lips.

Lynn turned positive. "The Olympiad is the foundation of all natural sciences. Chemistry is the discipline that studies the composition, structure, and changes of magic elements. As for physics, it is the exploration of the laws of the world's operation..."

"The purpose of studying these courses is to explore where magic comes from!" Lynn said firmly.

Where does magic come from?

Hearing this, the hearts of all the people present were trembling. Although they studied magic in the past, they seldom thought deeply about this issue.

Lynn continued to speak. "As for their function, I think you have seen it? The whole city is everywhere! You see glass, paper, airships, ships, and even electromagnetic rail guns, everything can be classified To these three disciplines!"

Thinking about what she had seen and heard since entering Iyeta, Fulla put away her contemptuous thoughts, and began to seriously examine each topic.

It's just that I haven't studied the Olympiad systematically, and I really don't know where to start to solve these equations for a while, so I can only look to Lin En for help.

Lin En raised his hand and tapped lightly, creating a sound-proof barrier nearby, before explaining.

"This question is actually easy to calculate, but it's just a little detour. If A and B have the same speed, then they will definitely reach the midpoint at the same time, but they meet at a distance of five kilometers from the midpoint, so the speed must be faster. Faster A walked twice as far as B, which is 10,000 meters."

"It took four hours for the two to meet each other, that is, A and B both walked for 4 hours, so we only need to perform a simple division operation, and it can be concluded that A's speed is 2.5 kilometers faster than B!"

Lynn explained the idea of ​​solving the problem as concisely as possible. This problem is actually not difficult, and it can be solved with a little use of the brain.

And the exam paper he gave had a total of fifty questions, with two points for each question, and a total score of one hundred. Sixty points is considered a pass, which means that only thirty questions need to be answered correctly!

The difficulty of these questions has also been carefully designed by Lynn. There are twenty-five "point-giving" questions like this, twenty "easy" questions, and five "more difficult" questions.

According to his prediction, if Ailoke and the others took notes seriously, it should be easy to do all the score-giving questions, and then they only need to do five 'simple' questions correctly to pass.

However, this is only a passing grade. Lynn hopes that there will be a few students with excellent grades for key training. They are all scientific research talents.

Of course, in addition to the "Liberal Arts" exam, these students have to take a practical course to test their actual combat and basic spellcasting ability, and the average of the two is used to determine whether an apprentice is qualified to become a formal wizard. This is also an extra opportunity for some partial students.

After Lin En analyzed a few Olympiad questions, Fulla and the others quickly experienced the joy of doing the questions, and began to ponder with a pen one by one, completely forgetting that they were here to supervise the exams of those students.

For Orlando, these "point-giving" questions are naturally nothing. After a few glances, he turned his attention to the questions that Lynn marked as easy on the test paper.

[A wizard driving an airship accidentally encountered an air crash. He jumped from a height of 480 meters. After free falling for a certain distance, he performed a slow fall technique and performed a uniform deceleration movement with an acceleration of 2 meters per second to reach the ground. When the speed is exactly zero, without considering the air resistance, find the total time of falling and the distance of free fall...]

Well, this should also be an equation problem.

Orlando thought about it. He remembered that Lynn said that free fall is a uniformly accelerated linear motion with an initial velocity of 0. The formula is v=gt, and g is the acceleration of gravity, which seems to be 10 meters per second? What is this t, should it be time?

But the falling body is divided into two parts, the time and distance of the fall are unknown, and it is an answer that needs to be found. Simply applying this formula will definitely not work...

Orlando pondered for a long time, cold sweat broke out on his forehead.

He realized that he... couldn't do it!

"Dean Lynn, these questions are too difficult, aren't they?" Orlando couldn't help reminding, you call these easy questions? !

Is this really what apprentices should do? Does he think this is a bit too outrageous?

"Is this difficult?" Lynn gave Orlando a strange look. He remembered that he had explained the relevant formulas and published them in [Magic Daily], so that wizards and even townspeople who are interested in studying calculations can learn more about them. Residents can also enjoy the fun of Mathematical Olympiad.

Moreover, every wizard is equivalent to a humanoid computer. Even apprentices have much stronger computing power than ordinary people. These problems should be within an acceptable range.

Lin En was about to explain when his face suddenly changed. He stretched out his hand and snapped his fingers. Magic power surged in the area around him. In an instant, a copper nail flew out and nailed an apprentice with lightning speed. On the quill and test paper I'm holding...
