Marine physics includes a wide range of knowledge, such as marine meteorology, marine acoustics, ocean optics, ocean electromagnetics, estuarine and coastal drives, ...... It mainly uses the theories, techniques and methods of physics to study various physical phenomena and their changes in the ocean.

Marine chemistry mainly studies the chemical composition, material distribution, chemical properties and chemical processes of various parts of the ocean, such as marine water and seabed sedimentation, marine water bodies, marine organisms, and the development of marine chemical resources.

Marine geology is the study of coastal and seafloor topography, marine sediments, ocean floor rocks, seabed tectonics, ocean geological history, and seabed mineral resources.

Marine bionics mainly studies the structural principles and functions of certain organisms, and imitates them in engineering technology to be applied, such as the naked sea butterfly project in Chili, which involves marine bionics.

It's hard enough to choose.

"Marine Bionics ......" Ikeri is a little excited about this major.

The teacher immediately explained to her: " The evolution of biology has a history of more than 3.5 billion years, and bionics is a young science, the future of people's exploration of the ocean, will be more useful for this profession, take jellyfish as an example, before the storm, the sea will produce a kind of infrasound, the speed of propagation is faster than the wind and waves, human ears can not hear infrasound waves, but the special receptors in the jellyfish can be felt, at this time, the jellyfish will quickly move away from the coast, so as not to be swept to the shore by the wind and waves, according to the mechanism of the jellyfish to receive low sound waves, people have created a storm siren, can predict the storm from a certain side 15 hours in advance。 Based on the current state of development, marine bionics is a profession that has attracted much attention. ”

Chi Li flipped through the college leaflet and thought about it.

The teacher said again: "It's okay, let's go to the school admissions office and sit down and rest for a while, drink some water and eat something to think about it." ”

Chi Li followed the teacher to the admissions office, and on the way sent a message to Xuncha.

Ikeri: Which do you think is better: marine physics, marine chemistry, marine geology, or marine bionics?

After a few minutes of looking for tea, he replied: Whichever one you think is fun, choose whichever one you want.

Whichever is fun...... This is a major in college, can you be serious?

So, Chi Li began to think about which major was more fun.

More than ten minutes later, she said to the teacher in the admissions office: "I have thought about it, marine bionics." ”

"Why did you decide on this major?"

Chi Li said seriously: "I feel that this major is a little more fun." ”

"It's fun...... the teacher tugged at the corners of his mouth, "Indeed, this major is quite interesting." ”

Immediately after, the teacher brought Chiri to the computer and asked Chiri to fill in various documents and procedures.

By the time all the formalities were completed, it was already eleven o'clock in the afternoon, and Ikeri had lunch at the school, then walked around the University of Minnesota, and walked around until dinner time before returning home.

Only the younger sister and the aunt are at home, and the aunt has prepared Chi Li's dinner alone, and Chi Li asked the aunt, "Haven't you come back yet?"

"Mr. Xun has always been very busy at work, and he used to stay at the company all night. Auntie said.

"What exactly does he do, so busy?" Chi Li asked curiously, she had never asked about the tea hunt, and had always assumed him to be the photocopyer in the copy room.
