So, normally at this point, we do actually start class with a little bit of history from alchemy to modern chemistry, but I decided to skip that this year.

通常在这个时候,我们要从一些从炼金术,到现代化学的历史出发正式开始我们的课程。

So, this will be a little bit more like a seminar to start with, and a little bit less like a lecture in class.

所以着看起来有点像是讨论课，而不是讲课。

So the Romans, for example, outlawed volunteer fire departments, in local places, because they were afraid that volunteer fire departments could be a place where locals, especially maybe lower-class locals, could get together and then start gossiping about what they could do to cause trouble for the Romans.

So, it seemed like a good start for me, pre-med/bio, and I signed up for my bio class -- I found out, as Professor Drennen did, that I had to take chemistry as well. I wasn't as upset, I was sort of a neutral chemistry person at this point, but I thought it was pretty smart to get it over with on the first semester, so that's what I did.

一个既在科学上有挑战又能帮助他人的职业，从医学预科或者生物起家-,我参加了生物课，我和Drennen教授一样，我也必须要上化学课，我并没有很不爽,我当时对化学的态度很中立。
