W: Oh, sorry to miss you. But my thirst for knowledge was greater than my pains of hunger.
M: So where were you?
W: My physical science class ran overtime. Actually, what happens is that some of us hang around for a while after class to talk with our professor and ask him questions.
M: Who is this 21st century's Newton?
W: Professor Greg, have you heard of him?
M: Yes. He does have a good reputation in the Physical Science Department.
W: And a well deserved one. The same students who Pall asleep in discussion group fight for front-row seats in his lectures.
M: Oh, on. I hope this isn't amazing.
W: You can joke. But it's great to have a professor who's not only interesting but prepares to give up time to students.
M: I know it is really rare. Maybe I should sit in his class some time. Do you think he'd care?
W: Not at all. Lots of students bring their friends. He says he feels flattered.
M: Well, just to be safe, I think I'll bring my dinner along as well.
W: I'll make a good student of you yet.

As your lab instructor, it is my duty to assist you in setting up your experiments and understanding your results. I will also grade your lab notebooks. But I have an even more basic responsibility: your physical safety. I will insist on proper precautions, such as wearing protective goggles at all times. I also expect you to use common sense: don't wear long scarves that might catch fire; don't smoke; don't taste unknown substances.
Let me reinforce this point with a story. Issac Newton, perhaps the greatest scientist of all ages, lived in a period when the toxic effects of chemicals were less understood than today. He routinely sniffed fumes, tasted chemicals, and used open containers for heating substances. In the early 1690s, he suffered through a period of insomnia, depression, and mental instability. Though his biographers linked this situation to problems in his personal life, researchers now think it was a consequence of his lab procedures; they found abnormally high concentrations of lead, mercury, and other heavy metals in preserved specimens of his hair.
Consequently, we must learn from the past and put safety first.
