I remember taking my first undergrad-level class in electrical after getting my physics degree. It took me forever to figure out how to do imaginary numbers on my seldom-used calculator. I still don’t know that I can graph things very well.

Yeah, graphing calculators are still my Achilles heel – something I really need to work on, for my students’ sake.

I remember walking up to my AP Calculus teacher the week before the test, saying, “How do you use this thing?” I don’t think I’d turned it on more than once or twice all year.

(And I never even THOUGHT about doing complex numbers on a graphing calculator! Although obviously they should have that capability.)

These days, if you can’t use a graphing calculator, then you are sunk on the AP test. For example — what if they ask you to integrate cos(x^2) from, say, 0 to 0.6? ? Some calculators can do it, but for all intents and purposes you can’t do it by hand at all.! And that was on the 2013 AP calc BC test.

Yeah, I always made sure to cover the really essential stuff with my students. (Graph equations; find roots; compute definite integrals.) But I know there’s tons of untapped power I wasn’t telling them about.

Of course you can do it by hand. The half-angle formula gives cos^2x – .5(1+cos(2x)).

That formula is a nice trick, but in this case, it’s the input (x) being squared, not the output (cosx). Also, even if it were (cosx)^2, I wouldn’t be able to compute the cosine of 1.2 radians by hand

I like exactness and proofs and writing QED, and find that I consider mistake-ridden work worthless, so in that sense I’m a mathematician. But I’m lazy, and will take an easy approximation any day, which is why I’m an engineer by trade. (Although I never relied too much on my graphing calculator, and never got the hang of the actual graphing or the more complex capabilities it offered.) I really enjoyed this post!

Well, I’m a Communications and Mass Media major who took mostly English classes, left without graduating to enter a Ph.D. program, left that shortly after, went on to a 30-year career as a computer programmer, and am now working as a professional ontologist. What does that make me?

I try my best, yes, though the full philological research program (to understand ancient cultures through their languages and literatures) is now too capacious for any one person to carry out. I should perhaps have mentioned that I spent my first undergraduate year as a physics major, and I remain a scientific American.

As an aspiring economist, I dream of the day we might be taken seriously by anybody.

Great post! Your Newton and Leibniz are definitely not Bad Drawings. I’m curious if there is a word for what mathematicians might call a simplified representation of reality?

Mathematicians don’t care much about reality in the first place; they’re always working with abstractions and idealizations. So I think they just call it “mathematics”!

I have friends who like discussing quantum physics/reality and friends who are mathy.

Unfortunately, they are the same friend and I have to smack him on the forehead every few sentences to get him to stop using math analogies for everything as if they were Aesop’s Fables.

Must show this to my math-major boyfriend! It also reminds me of the time I tried to teach a group of nine-year-olds how to do proofs:
“But why can’t you just say it’s true?”
“Because I’m in high school.”
“What else do they teach you in high school?”
“Right – uh who wants to learn how to count in Spanish?”

I just read this aloud at an extended family dinner filled with mathematicians and computer scientists who are also the descendants of an accountant. There was much hilarity. 🙂

Typo: should be Leibniz.

Yikes! Will fix.

This was excellent and terribly funny 😀 and I love that you included us unemployed English majors haha

Annoyingly difficult to stereotype?

Do you recapitulate philology?

As a Physicist student, i disagree with the calculus one. Leibniz is for Physics, Cauchy for Matematics!

As a math major, I like to switch the letters and Cettle Satan.

Great illusions causes great fluctuations in the stratosphere. In other words hot air rises.

Hysterical.

That went over so well I majored in it!

I have to share this with my physicist son! What a riot!

This is great!

Couldn’t like this more.

A lot of this went over my pleb humanities-taking head, but it was good! I loved the burns on economics too – so true.
