Gravimeter: Precision measurement of gravity | informal science

● Eating, sleeping, playing games... of course, scientific research, is the daily life of Xiao Mo Meow and Little Orange. As a result of the Shanghai Research Institute of the University of Science and Technology of China, they do not consciously have more "quantum" shadows when they eat and play games. Let's take a look at their daily life (da) life (da) love (sha) fun (sha), and by the way, understand the scientific research work that happens around them.

In this "informal science" series, you will learn: non-field-of-view imaging technology that makes light "bend", computing power quantum computers, truly unpredictable random numbers, unbreakable quantum communication, ultracold atoms at very low temperatures, and gravimeters, light clocks, and so on that use ultracold atoms.

Our fifth stop: the Quantum Gravity Meter.

There are slight differences in the acceleration of gravity in different parts of the earth, and a gravimeter is an instrument that measures the acceleration of gravity. What is the use of accurately measuring the acceleration of gravity? What can quantum physics do for the precise measurement of gravity?

Mozi Salon is a large-scale public welfare science popularization forum named after the Chinese sage "Mozi", hosted by the Shanghai Research Institute of the University of Science and Technology of China, and co-organized by the Xinchuang Alumni Foundation of the University of Science and Technology of China, the Education Foundation of the University of Science and Technology of China, the Pudong New Area Science and Technology Association, the China Association for Science and Technology and the Pudong New Area Science and Technology and Economic Committee.

Mozi is a famous thinker and scientist in ancient China, whose ideas and achievements are the embodiment of the budding of early science in China, and the establishment of the "Mozi Salon" aims to inherit and carry forward the scientific tradition, build a social atmosphere advocating science, enhance the scientific literacy of citizens, and advocate and carry forward the spirit of science. The object of popular science is the general public who loves science, has the spirit of exploration and curiosity, and we hope that the public with the equivalent academic strength of middle school and above can understand and appreciate the most cutting-edge scientific progress and scientific ideas in the world.
