Last night was the first session of my Physics class and just like every other new class and new semester, I became introduced to all kinds of new people. It's always a gamble with the professor though, you never quite know what to expect.
First off, the professor walks in and he is terribly skinny, and severely bearded. One could easily mistake this guy for a truck driver or a family member on Duck Dynasty. He talks just like Tommy Chong.... "yeah maaaaan."
In the middle of his wandering discussion, he asks "Why is the sky blue, man?"
I raise my hand and answer (my first mistake of the class), "Because of Rayleigh Scattering."
"No, because the light is bent in the atmosphere, like a pencil in a glass of water," he responds.
I didn't go further with it out of respect for his class, but this hippy was dead wrong.
The blue color of the sky is most definitely due to Rayleigh Scattering, and not Refraction as he said. The fact that he doesn't know this, doesn't really instill too much confidence. Okay, okay... I can hear you all now. I'm being a little Judgy McJudgerson right? Maybe, but I kind of enjoy science and math. I'm on my way to becoming a fully qualified engineer. I should care about this stuff right?
The class goes on and we get into the meat of the class lecture, Kinematics. YES! This stuff is fresh on my mind, I just finished Dynamics. Dynamics was part of my Applied Mechanics courses and is, more or less, the same thing as Physics. We start with basic displacement problems and soon after, I realize this guy doesn't really know what he is doing. He's writing an example problem on the board and is doing the problem wrong! Again, I didn't say anything, but let him go do his thing.
I'm not really looking forward to the rest of this semester. Sometimes, I just hate school.
Oh yeah... the book was ridiculously expensive too, another reason to gripe.
