19. 决定读研
• 如何决定读研?
– 博士生、硕士生都叫研究生
– 材料学研究方向的博士学位主要就业面:
• 高校、研究所:正式以科学研究为职业
• 有实力的企业的销售、研发、售后岗位
– One of the goals of education is to make people aware of how
little they know. An undergraduate major acquires a great deal
of knowledge, but there are many (fun!) things that you do not
have time to explore. The excitement of exploring the cutting
edge of knowledge, and the thrill of your first research result,
something you have discovered that no one else in the world
knows, are worth savoring.
