First of all, there may be some changes. Our life will be stimulated, our life will be greatly changed and our life will be more efficient. Appraisal of scientific and technological achievements is one of the methods to evaluate the quality and level of scientific and technological achievements. We can encourage scientific and technological achievements to be evaluated and recognized through market competition and academic schools, so as to promote the progress, popularization and transformation of scientific and technological achievements. In the past, everyone thought that time was one minute, equal to 6 seconds, and one hour was equal to 6 minutes. If we redefine seconds, we may have a different understanding of time. ?

Secondly, appraisal of scientific and technological achievements is one of the methods to evaluate the quality and level of scientific and technological achievements. Scientific and technological achievements can be encouraged to be evaluated and recognized through market competition and academic schools, thus promoting the progress, popularization and transformation of scientific and technological achievements. After a generation of efforts, the history of human society has been quite accurate, and there will be no major disaster, so under certain conditions, scientific and technological achievements will still play a certain role.

Furthermore, the free and high-precision time-frequency transmission experiment in space shows that the stability of time transmission reaches the order of femtosecond, and the error is only one second every 8 billion years. This feat is an important step to redefine seconds with optical clocks. In this study, after a series of technical breakthroughs, the research team successfully achieved free-space time-frequency transmission of 113km, compared with 16km before. Research shows that when measured in hours, they can spread signals with high enough stability.

it is important to know that the feasibility of high-precision optical frequency standard comparison between satellite and ground links is an important step to establish a wide-area optical frequency standard network. It will have an important impact on basic physics research such as dark matter detection, basic physical constant test and relativity test. Generally speaking, this research is closely related to everyone's life, such as satellite navigation, geodesy, geological exploration, radar detection and other fields related to people's livelihood. More and more accurate time measurement will bring more and more convenient experience.
