  They also work great for getting PETG prints to release from PEI build plates. Flip the can upside down, spray at the back of the sheet where the print is until it forms a thin layer of frost. Wait until the frost disappears (really you’re waiting for the metal to contract, but you won’t see that), bend the plate, and the part should pop right off.

  …then flee to somewhere better ventilated to escape the cloud of bitterant before you vomit.

  OP isn’t referencing “the imaginary numbers” as in the set of numbers that are multiples of the square root of -1. They’re referencing the fact that in grad school, you’re told “forget everything you’ve been taught about math up to now. We’re going to start with a couple of basic assumptions, and extrapolate all of Cartesian Algebra (the math taught in preschool through undergrad) from those assumptions. Now, let’s see what other algebras we can create by changing those assumptions.”

  The only two “numbers” that need to exist to derive all of Cartesian Algebra are zero (additive identity) and one (multiplicative identity). All other numbers are just convenient identifiers that can be extrapolated rather than assumed, hence the overly simplified “all numbers are imaginary”.

  This is similar to other STEM subjects, like how in Physics you’re taught Newtonian physics, then you’re taught why Newtonian physics is just a tiny subset of relativistic physics, and then in grad school you are taught everything you know is just a tiny subset of quantum mechanics. What’s taught in undergrad is “good enough” for your average person to do really complex things in typical day to day life, but for someone dedicating their academic career to the subject, they need to learn the dirty, overly complex details to have a true understanding of the subject.

  You shouldn’t wear Depends in the shower. They’re for getting back to that squishy feeling after the shower.

  That’s because the person who had the solution removed their comment history, but the person who said thank you didn’t.
