At 2:50, Professor Tao slowly walked up to the podium.

There are simply too many applicants.

“I’m glad that people are interested in high-dimensional space.”

Professor Tao looked at the students in the hall and paused slightly. Their eyes were mixed with various things, but no one was looking at the podium.

“Ahem.”

Professor Tao coughed.

The students then turned their gazes over. After all, one had to appear to be okay on the surface first in order to perfectly hide his infatuated behavior.

Professor Tao nodded with satisfaction.

"The concept of high-dimensional space has always been a sensational and mysterious existence."

“People who are interested in this concept hope to find a world that breaks the limits of imagination.”

The students had to think along the lines of Professor Tao's words.

A world that breaks the limits of imagination. There are many of them in science fiction movies, such as the Infinity Stones, or Thanos destroying the world with a snap of his fingers.

I've watched so many movies that there's nothing I can't imagine.

The students thought that Professor Tao was sensationalizing and trying to attract attention.

But Professor Tao on the podium seemed to understand the students' expressions and smiled. "Indeed, the concept of a higher-dimensional world is not new, but people have been discussing it over and over again, but few people know where the term higher-dimensional comes from."

The students thought about it.

It is true. Few people have explained the original meaning of "high dimension".

Professor Tao said very calmly: "The concept of dimension comes from mathematics. It is also called dimension, which is the number of independent parameters in mathematics."

"It is a kind of background reference, the foundation of human mathematics."

“Newton’s classical physics, Maxwell’s equations, and even Einstein’s theory of relativity are all based on this.”

"but."

Professor Tao's eyes suddenly flickered. "This series of various mathematical formulas do not have corresponding dimensional restrictions. Those equations can be solved in reality and are called iron laws. However, in high-dimensional space, they may be completely wrong formulas. And the higher the dimension, the more outrageous the error!"

"Suppose we change the dimension."

"The length, width, height, coldness, heat, softness, hardness, and so on of objects, as well as the so-called maximum speed of light and the uncontrollability of time, can all be easily overturned."

"so."

“No one can imagine what a higher-dimensional space would look like if all laws were broken.”

Professor Tao looked at everyone and said, "After all, it is not easy for everyone to break out of the inherent knowledge system."

The students were suddenly stunned.

So, all the advanced mathematics I learned before has to be overturned? That's good.

But at the same time, they also realized a hint of mystery.

Only Brother Liu nodded secretly.

Suddenly a student raised his hand and said, "Professor! Do higher-dimensional creatures definitely have superpowers?"

Professor Tao shook his head. "Superpowers are not enough to describe dimensions. Dimensions are another space parallel to ours. Above three dimensions, you can't see or touch them. This is a breakthrough in the gap between life levels. The basic abilities of living things should be what you consider superpowers."

Immediately, Professor Tao smiled and said, "I will do my best to describe this high-dimensional world to you!"

Before you know it.

A group of students began to stare at the podium.

Professor Tao put a chalk dot on the blackboard and said, "A dot is zero-dimensional. A string of them is one-dimensional. Four lines form a square, which is two-dimensional. And three-dimensional is the accumulation of countless two-dimensional things, which is equivalent to a cube, just like us..."

Suddenly a student interrupted and said, "Professor, we all know this. You can just 'upgrade'!"

"Understand?"

Professor Tao shook his head and smiled, "It's best not to ignore the first and second dimensions, because there are also life forms hidden there that you can't imagine, such as the shadow that is omnipresent and follows you everywhere."

Hiss. The students were suddenly stunned and looked at the shadow beside them. If this guy had his own life, it would be scary enough. Even if they shone a flashlight in the quilt, it would be there!

But Officer Tao Wutian just laughed and said, "This old man has a weird theory. If the shadow really comes to life and commits some illegal crime, my head will explode on the spot."

Brother Liu was also staring at his own shadow in deep thought. The more he looked at the shadow, the weirder it seemed.

What the professor said was not funny at all.

Since there are four-dimensional creatures looking down on us, we can naturally look down on two-dimensional creatures!

There is no mistake in the poem, post, content, and read the book on 6, 9, and bar!

Professor Tao put down his chalk and continued, "The fourth dimension is to add a time variable. The creatures in it can see time as a straight line. They can stay at any time. They can watch the birth of the earth and the evolution of life with their own eyes."

"And the fifth dimension can further strengthen this variable and allow the timeline to break through to the future!"

"To see someone's birth, aging, illness and death, glory or desolation in an instant is transcendent."

A student shouted: "Is this understandable? It's time travel! Professor, what is the sixth dimension?"

"Although the fourth and fifth dimensions can travel through time, they are illusory. Only when we reach the sixth dimension can we touch and interfere with the timeline."

Professor Tao said slowly.

"Um?"

A student asked, "Is this what the sixth dimension is like? It doesn't seem that strong!"

Professor Tao shook his head and said seriously: "Observation and interference are two completely different states!"

But Brother Liu was confused.

He raised his hand slowly.

All kinds of eyes gathered over at once.

My male god is going to speak?!

So handsome.

Before she knew it, SSS's ultimate goal had become her male god.

Liu Di said: "Professor, but I...Oh, I have a friend who believes that he can touch reality in four or five dimensions, but six dimensions are the future, and the order is different from what you said."

Professor Tao's eyes flickered. "High dimensions overturn everything. There is no order. Perhaps your friend has created a new path."

Liu Di was still puzzled: "How do I determine my friend's dimensional level?"

Professor Tao smiled and said, "Dimension is not a level, but a kind of existence. When you have the ability in it, aren't you a so-called high-dimensional creature?"

Brother Liu seemed to be thinking about something.

But the girls who like appearance kept clicking their tongues, saying that they didn’t expect the male idol is actually a middle school boy. What do your friends think?

Making friends out of nothing.

I'm afraid that's just your fantasy! But at this moment, the thoughtful Liu brother suddenly asked: "Professor, what is the seventh dimension?"

Professor Tao looked at Brother Liu approvingly, "Above the seventh dimension, it's beyond imagination."
