Science is a wonderful thing if one does not have to earn one's living at it.
科学不仅仅是关于事实,更是关于提出正确的问题。
What you actually pay for something is at least twice the listed price because of the energy, time, money needed to set it up, learn, maintain, repair, and dispose of at the end. Not all prices appear on labels. Actual costs are 2x listed prices.
I don't think about being a role model. I just try to be the best person I can be.
