If y = r3/3
Then dy = r2.dr == r.dr.r, or "Har-Dee-Har-Har"
Ah, so that's what it is. (A Simpsons joke that I do not remember? Shame on me!)
Personally I'm into Physics, so I'm not fuzzy with where I put the dr. (I did get it down to the r^2dr form, but I totally didn't see the Har-Dee-Har-Har.

To be strictly accurate, the number would have to be (pure) imaginary for that to work, rather than simply not real.
If a number lies outside of the real line, it is imaginary. That is, it HAS to be expressed in form of A+Bi.
Not all scientists are very boring. Why, I have lengthy conversation with my friends about going on a huge trip to find magnetic monopoles. We believed it is just beyond the pot of gold at the end of the rainbow, hidden by some unicorns. But we probably have to track down a bigfoot so we can steal the map to get to the end of the rainbow first.
Unfortunately the trip didn't happen because nobody wants to explain all those to the admin when we ask them to fund our project.
Also, physicists have the nicest facial hair out of all professions.
By the way, why does water put out fire? Does it evaporate at relatively low temp so it sucks out all the energy or what?
