We can break the integrand , as well as the differential into their real and imaginary components:
In this case we have

Oh, memories. I used to tutor these equations in high school, back before I realized you got a lot more ladies as an artist than as a math prodigy.

I used to use Cauchy to school dudes who questioned the continuity of BrikWars's exploding dice progression. (For no reason, since simple algebra did it more directly.)
But Riemann is my favorite mathematician, because in 1851 he's lecturing about how these equations could be used to rotate three-dimensional space through an imaginary fourth dimension, but of course it's just a folly since rotating through the fourth dimension has no practical application.
Ten years later, up shows James Maxwell saying I don't know what the deal is, but it looks like those "bullshit extra dimensions" equations perfectly describe the relationship between electricity and magnetism... and everyone in the world's MIND is BLOWN. Out of nowhere we get the occultist paradimensional obsession of the late 19th and early 20th centuries, which hits its peak with Rasputin and Houdini, but its purest expression in Lovecraft's stories about fourth-dimensional lifeforms.
And as if that's not enough, Einstein shows up in 1906 with some new thoughts on electromagnetic propagation through curved space, the world goes crazy again... not realizing that his fancy equations are the exact same ones that Riemann presented in 1854, again having told everyone that they're mathematically fascinating but there's no possible practical use for them. Next thing you know, mushroom clouds are going up over the Japanese countryside.
The internet wants you to believe that Tesla was the father of the twentieth century. Tesla can suck it! Riemann gave us Cthulhu AND nukes.

Einstein wasn't a math prodigy. He was a special relativity prodigy. Ladies had no defense against his special relations.
