true or false...

Would you say this is true or false:  one of the essentials to being a "good" programmer is being able to implement mathematical concepts even if you don't immediately fully understand the theory behind them.  Like implementing what you see verbatim from a math book into your program, even if you still have no idea most of what the math reference is saying, you still get it to work properly in your program.

like quaternions... I got tired of trying to figure out *why* they work, and *why* imaginary numbers would have anything to do with geometry with very little success in figuring it out... so I ignore that part and just **trust** that my math references are correct, and go straight to the implementation.

I sometimes feel like a "bad programmer" when i do this, but... maybe I'm just a bad mathematician (calculus certainly held me back a couple of college semesters) and maybe actually a better programmer than i give myself credit for, if I'm able to implement concepts working that I don't fully understand in my own mind in my software, perhaps?

I allowed him to pull me up onto my knees and I widened the stance of my legs, opening wide to him. My chest was flat against the sheets, and my arms were flung out wide, my fists gathering and releasing bunches of bedspread and sheeting in rhythm with the furious stroking that he, on his knees between my legs, was applying with that long, draggy cock of his inside me. As I knew it would, that cock of his was putting me in the mood for him. I cried out for him, loving those long deep strokes. I writhed underneath him, as he plowed me hard and long. I loved the feel of the sliding uncut cock inside me.
 
With a cry of exultation, he came inside me, flooding me, no need for any protection between us now beyond the rings of pledge on our fingers.
 
We collapsed on the bed, and he stroked me off to ejaculation with his hand. The loving, caring partner. I could feel him stirring again, and he wanted more, but one of us had to be sensible. He had a class to go teach and I needed to get to work on the new chapter of my novel.
