Shen Qi borrowed a car from the Guiyang Mathematical Association, and he will drive his daughter to Kedu Town.

The matter of borrowing the car has already been connected, and the Guiyang Mathematics Association has installed child seats in the car very intimately, and asked Shen Qi if he needs a local guide.

Shen Qiwan rejected their kindness, he just wanted to be with his daughter quietly.

The second day of the May Day holiday.

Shen Qi's father and daughter got into the car, and Shen Qi drove one kilometer manually into the intelligent highway network.

"Xiaoqing, switch to autopilot mode. Shen Qi said to the steering wheel.

A sweet female voice sounded in the car: "Okay, according to the preset route, Xiaoqing has switched to L4 level automatic driving mode for the owner." I have detected that the child seat has been loaded with passengers, do you need Xiaoqing to play a song suitable for children to enjoy?"

Before Shen Qi could reply, Shen Nuofei said skillfully: "I want to listen to "You Are a Liar". ”

Xiaoqing was silent for a few seconds, presumably analyzing the sound data.

After a while, Xiaoqing said: ""You are a liar" is about to be played for the master and the little master, Xiaoqing warmly reminds that the L4 level of automatic driving needs to be answered by the master when it encounters an emergency. There are thousands of roads, safety first, driving should be standardized, relatives do not shed tears, I wish the owner and the little master a happy time in Kedu Town. ”

The cheerful music of "You Are a Liar" sounded in the car, Shen Qi threw away the steering wheel and released the accelerator, and he did not forget to pay attention to the road situation while talking to Nofi.

Xiaoqing is an on-board artificial intelligence, Shen Nuofei is very familiar with this thing, and the artificial intelligence in her parents' car is more advanced.

With the continuous improvement of autonomous driving technology and intelligent highway network, L4 autonomous driving has been achieved in some parts of China, and in the foreseeable future, L5 (i.e., fully autonomous driving) will enter the stage of commercial popularization.

Driving out of the smart highway network and onto the county road, Shen Qi switched to manual driving mode, and the father and daughter arrived in Kedu Town in the afternoon.

The 500-meter-aperture China Sky Eye is the world's largest radio telescope, and it is located in the Dawotai Karst Valley, not far from the town of Kedu.

The main use of China's Tianyan is scientific research, and its fame is very large, attracting many tourists to travel.

There is a shuttle bus to the China Tianyan Viewing Platform in Kedu Town, and most tourists choose to take the shuttle bus to the viewing platform during the day.

Shen Qi's father and daughter lived in the staff dormitory of the Academy of Sciences in Kedu Town, the competent department of China's Tianyan, and a large number of astronomers and cosmophysicists have been stationed in Kedu Town for a long time.

Room 79649, this is where Shen Qi's father and daughter stayed.

The small one-bedroom apartment is small in size, the interior is clean and tidy, and an optical telescope is placed under the windowsill of the living room, and the lens is pointed at the sky.

The asteroid 79649 is also known as the "Nanren East Star", and this apartment was originally room 202, which was the room of Academician Nan, and was later changed to room 79649.

Shen Qi came to the optical telescope under the windowsill, the 10-inch Schmidt-Cassegrain telescope was produced in 2007, and it was the equipment used by Academician Nan during his lifetime.

There is also a domestic 15-inch optical telescope in the corner of the living room, as well as two portable binoculars.

In principle, Academician Nan's 10-inch Shika telescope cannot be taken out of the room, so the Academy of Sciences prepared a new 15-inch optical telescope and binoculars for Shen Qi's father and daughter.

The 15-inch optical telescope was a big guy, and it took Shen Qi a lot of effort to move it into the trunk of the car.

As the sun set, Shen Qi drove his daughter to Tianyan, China.

Opening the car window, the fresh air moistened his lungs, and Shen Nuofei squinted his eyes pleasantly: "It's so comfortable." ”

In areas with severe smog, it is difficult to make astronomical observations with optical telescopes, and even radio telescope observations have been affected to a certain extent.

There are no heavy industry factories around Tianyan in China, and it is an excellent place for astronomical observations.

Huge ears with a diameter of 500 meters lie quietly among the mountains, listening to the sounds and signals from the depths of the universe.

The setting sun shines on the surface of FAST, gilding it with a golden glow.

"These are big eyes, huh?" Shen Nuofei saw the Chinese Sky Eye, and she wondered, why doesn't this thing look like eyes?

"FAST, that is, this big guy in front of you Nofi, its more appropriate nickname should be called Chinese Tian'er, it is used to listen, so it is the ear. ”

Shen Qi picked up the binoculars and shook them, and he explained to Nofi: "This small telescope in Dad's hand is an optical telescope, through which you can directly see the stars, it is an eye. ”

Shen Qi pointed to FAST and said, "That's a radio telescope, it can hear rays and radio waves in the universe, so as to quantitatively and qualitatively describe the stars, it is the ear." Optics and radio astronomy are very difficult knowledge for Nofi, and you may not understand it at all now, but it doesn't matter, you will understand it later. ”

"It's the eyes. Nofi looked at the binoculars and then at the huge 500-meter aperture radio telescope: "That's the ear, I see." ”

"Nofi was awesome. ”

Shen Qi parked the car, and he began to install a 15-inch optical telescope.

At night, the tourists in the karst pits of Dawotai return to Kedu Town or go to other towns.

Shen Qi installed the 15-inch optical telescope and debugged it OK.

Under the night sky, everything was so silent.

The temperature difference between morning and evening in the mountains is large, and Shen Qi took out a wool shawl and wrapped Nofi.

Shen Qi adjusted the eyepiece to a position where Nofi could observe, he squatted down, and the father and daughter looked at the brilliant galaxy head to head, identifying the bright and dark stars in the night sky.

"Do you know Nofi, the place where we live is called the earth, and the earth is a star, and in the universe, there are many, many different stars. ”

"It's beautiful!"

Saturn is the superstar of the night sky, and its beautiful little round ball floats in a black velvety field of view, surrounded by a delicate halo that makes Saturn so special.

Jupiter is a giant in the solar system, and its foreign name is Jupiter--- corresponding to Zeus in Greek mythology. Jupiter's strange changes in clouds make it look like a colorful beach volleyball, suspended in the air by invisible ropes.

Shen Qi guided Nofi to look deeper and farther into the depths of the universe, where the absolute magnitude of Ophiuchus α was 0.96, and even though it was 54 light-years away, it was bright and moving.

Shen Nuofei, who was stargazing for the first time, became interested in the stars: "Dad, is there anyone living on those stars?"

Shen Qi shook his head and said, "We haven't found anyone living on other stars yet. ”

Nofi asked, "Can we go and live?"

"Dad didn't know about this either. When Nofi grows up and learns a lot, you'll be able to study the problems of the stars and the mysteries of the universe on your own. ”

"Then I'm going to grow up quickly, Dad, I'm hungry. ”
