The blogger's personal opinion is that there is no distinction between arts and sciences for basic content learning, it all belongs to the liberal arts, and a big feature of the liberal arts is memorization and recitation. Carefully recall the secondary school, learning mathematics, science and chemistry are not to memorize the core knowledge points and formulas and methods, in order to be able to understand the new knowledge points and topics, in order to be able to go through the understanding of the memory, or through the logical deduction of the memory, often this time feel in the study of science, but do not know that the premise for doing so is to have memorized the basic knowledge and formulas, in order to launch the subsequent results. Memorization is the basis of that, there is no way to draw more conclusions without anything. Therefore, everything is liberal arts and everything begins with memorization is to emphasize the importance of memorization and not to resist memorization because it is the beginning of everything. You have to memorize before you can follow up. If you don't have anything in your head, you can't make any waves, because you don't know what waves are, and you can only create new waves after you've seen them.
