Hi, Honey, I've reentered the domestic habitat!

The following conversation is a near word-perfect transcription of a typical conversation between me and The Husband as we discuss our days.

THE HUSBAND: You know antifreeze?
MO: Uh... yeah?
TH: I froze it today.
MO: Well, everything freezes eventually.*
TH: We had to run a test at -40 Celsius --
MO: Which is also -40 Fahrenheit!
TH: I know! One time I tried to convert -40C to Fahrenheit in my calculator, and it came back as -40! I did it three times before I realized.
MO: Well, the lines aren't parallel! They have to intersect at some point, right?
TH: Yeah. So anyway, antifreeze freezes at -50F, and we had cooled it so quickly that we overshot -40F, and it froze.
MO: That's pretty cold.
TH: So we're going to run it with ethanol instead, since that freezes below -120C.
MO: Ethanol or ethylene glycol?
TH: Ethanol.

*The Husband helped me remember this conversation, and he maintains that not everything freezes. I said that even hydrogen freezes at absolute zero, and he said no it doesn't. I still think it does, but I suppose he might be right, now that I'm typing this, because I guess that freezing is not the same thing as a cessation of molecular vibration. And yes, I'm typing this footnote as an excuse to write the phrase "cessation of molecular vibration," because I like to show off sometimes.

Awesome! My husband and I are both engineers too. I know exactly where you are coming from.
