After Archimedes and Vitruvius era, for more than 2000 years, it has been believed that the displacedwater measurement of golden crown is impossible, and at his Eureka moment, Archimedes discovered theArchimedes measured the weight of displaced water.
After which, Archimedes continued to measure the specific gravity of various solids and fluidsIn this paper, the process to the discovery of Archimedes’ principle (Proposition 5) is presented

The obligation of decryption assistance by Internet service providers reflects the conflict between public power (the power of investigation) and the right of privacy (the right of communication privacy, private rights). Internet service providers should gather data under encryption by users on the basis of the principles of controllability and traceability, proportionality, and necessity. Providers should consider choosing their path prudently, supervised by strict procedure. Thus, the overall utility of social governance control, the tranquility of private life, and the business interests of Internet service providers can be maximized. Severe violations of private rights and disorderly situations due to governmental failure can be avoided if these suggestions are carried out.
