The cuttlefish kill physicists in a dream sequence and XKCD is conspiring with biology majors to kill chemists. I fail to see any threat or relevance to mathematicians.

We'd be too busy measuring exactly how well the shell models φ anyway.
Master has given Dobby a doctorate! Dobby is free!
Chemistry (my major ), Physics, Biology. Though I'd have to say anything that deals with outer space would be above even Chemistry. Biology is the least favorite; living things are despicable.
Though being a Mathematics major also entitles me to maximum purity.
Why does he keep saying things in terms of cubic meters? Is using mL taboo?
I've actually wondered this for awhile. Why do you hear in medical shows "i need 10 CC's of bladyblah"?
Well he didn't even say CC, just "cubic centimeter". Bothers me.
Then again that's not the only thing that bothers me in chemistry. There's also the official scientific notation of, say, 6.022 × 10²³ instead of the clearly superior calculator notation of 6.022e23 (or 6.022E23). The e can't even be confused with the natural number e because variables and constants aren't written before numbers.
I mean it pretty much goes against every good habit you learn in mathematics and adds useless length to numbers. Like not using × to represent multiplication because it could be mistaken for an x, or not using · (interpunct) because it could be mistaken for a decimal. Parenthesis, as I have been taught, are the safe way to clearly indicate that a number is being multiplied if juxtaposition is insufficient.
But every professor I've asked was okay with me doing it this way, so long as I wrote a note on my tests and graded homework.
In many scientific fields, the use of cubic centimetres has been replaced by the millilitre. The medical and automotive fields are two of the few fields wherein the term cubic centimetre was never discontinued in the United States.
It's quite fine to use cubic centimeter, since it's the same as mL anyway.
What bugs me is that the dude in the video uses cubic centimeter AND cubic decimeters
please just use liters or just stick to one unit. Even if it's because the concentrations greatly vary, it's still easier and better to hear someone say "number times 10 to the power of number" than hear random units being spouted.
