0, 1, 1, 2, 2, 3, 3, 4, 4 ... what is the function for that numbers ? sorry for my bad english, i'm not sure if function is the right word. I mean f(1) =0, f(2), f(3) = 1, whats that function ?

Why is calculus so depressing? It's supposed to be simple as fuck, yet I'm sitting here looking at the tasks our prof gave us and it only makes me want to jump out the window.
I never liked math, but was fairly good at it, but the jump between high school and this is just insane. I'm sweating, can't focus on a single thing for longer than 10 seconds and my stomach feels like it's going to implode.
What the fuck is happening to me? Did I just reach the limit of my intellectuals capabilities?
I don't want to be retarded, I think I'm gonna be an hero.
Did /sci/ feel the same on their first year?

Why might a genetic resistance to antibiotics not go to fixation in a bacterial population?
This question was on a test I had at the beginning of this semester. I said that the genes for antibacterial resistance might be recessive, or that the population wasn't exposed to antibacterial agents all at once, preserving some of the individuals without the genetic resistance. I got the question wrong, and the teacher didn't give me a correction or explanation, so I'm pretty confused.
What do you think, /sci/?

Hey neuro/sci/, can you tell me what kind of interfaces there exist between a particular skeletal muscle and the cortex?
In pic related there is the Ia sensory neuron, which increases or decreases its rate of fire as the rate of change in muscle length increases or decreases.
I'm also aware of the type II sensory fiber, which increases or decreases its rate of fire as the muscle length itself increases or decreases.
Interesting how both l (muscle length) and dl/dt are being monitored, but is this the whole picture that the cortex gets of arm kinematics (other than visual cues) or is there anything keeping track of the actual exertion of the muscle for monitoring cases like increased load bearing?
The way it's described in the video, the Ia sensory neuron is the only one implicated in the circuit involved in a myotatic reflex, but there must be more to the picture if things like the goal encoding (that the arm actually WANTS to be kept at the same angle) is to be accounted for, or am I mistaken?
