Quiz: Physics constants

Constants are physical sizes that have a constant value. The names were honored by renowned scientists like Avogard, Stefan and Boltzman. When their values are determined they do not change. Many constants have values written by a scientific record because they are either very large or very small. On the Internet we can find a list of all physical constants, and before you find it, check out your knowledge in this quiz.
