Information
  It is difficult to distinguish the difference between it and ordinary glass only from the appearance. But it has an amazing "memory" and can keep a record of what happened around it. The recording method is not like traditional electronic tools, it is through the changes in the arrangement of internal memory molecules to complete the memory of things. When you need to read and read memory, you can use a special translation machine to translate molecular language into images and display it.
   principle
   Cover a piece of paper with text and images on a piece of transparent glass, and then use short-wave ultraviolet, X-rays, and gamma rays to carry out high-energy electromagnetic radiation. The glass can automatically "memorize" these texts and images. When illuminated by long-wave light sources such as sunlight, the glass stored in a dark background can still reproduce text and images.
  the study
  As early as 1996, physicists at Harvard University in the United States envisioned writing information into a durable, glass-like transparent material. The glass can resist high temperature burning, chemical corrosion and mechanical damage, and even has bulletproof function. Scientists have really worked hard to realize this idea. It's not that glass is difficult to make, but that the laser beam is difficult to precisely control. If you don't pay attention, the tiny patterns carved out will be wrong. Fortunately, this problem has been resolved. As soon as a Japanese company heard about this achievement, it couldn't wait to seize the opportunity to apply this technology to fused silica (a glass-like material) to develop new information storage products and plan to market it in the next few years.
   British physicist Kazanski is also interested in this technology. He considered whether it is possible to engrave a notch with 5 kinds of information at the same time on quartz, that is, not only reflect the changes in three-dimensional space (length, width, and depth), but also record the intensity and polarization of the incident laser pulse. In this way, the information storage density is 8 times higher than that of the Japanese company. It can store trillions of information on a nail-sized quartz material, that is, it can store 5 million books with 100,000 words each, which is almost a large library. Tuck in 2 "nails". Moreover, Kazansky speculated based on the test results that the information stored in this material can withstand high temperatures of 1000 ℃, can escape the damage of a nuclear explosion, can be safely stored for 10 billion years, and its life span is almost coexisted with the universe, and the sun and the moon shine together.
   effect
After the    memory glass technology is put into practical application, the police can track the whereabouts of the criminal several years ago within a "nail". In addition, the Meteorological Observatory can track the changes on the earth in the "nail", and future humans and even aliens can also use this technology to understand the living conditions and civilization achievements of our generations.
   After the "light storage" technology is further mature, the application prospect of this kind of glass in the high-tech field is unlimited.
