Introduction to programming
>Students who earn a passing grade on 8 problem sets (programming assignments - 15-20 hours each), 2 quizzes, and a final project will get an honor code certificate from HarvardX. Students may take CS50x at their own pace, starting anytime after October 15, 2012 and finishing anytime before April 15, 2013.
>None. CS50x is designed for students with or without prior programming experience.

Confessions of a Particle Physicist

I must admit something.
My name is Dr. Richard T. Bale, and I hate every single one of you. I'm a practiced particle physicist for the last 32 years; graduated with honors from Duke in my early 20s, then having gained my Ph.D in physics from Edinburgh shortly thereafter. I was soon picked up by company to remain unnamed for various projects, including the search for the Higgs Boson, which had lead me to a short employement at CERN within these last few years.
...we make it all up...
Not a damned night goes by in how I wonder that we've come to far by such an asinine and preposterous understanding of science. There are times I compare my practice to that of spinning a bottle at some 14-year-old girl's birthday, regarding how we choose our fundamental deductions. Frankly, I haven't the slightly inkling how we've not yet blown ourselves up save for some unfortunate people in Japan, for whom we are wholly responsible in crimes against humanity. We're ignorant children playing with a lighter, enamored by the flame in a tribal-like delusion of strength and power, and one of these days we're going to burn down our homes, lands, and very existance from this little blue ball we call Earth.
I've retired early in disgust with these so-called "sciences", and pray those aspiring in the same field do not lower themselves to be clowns in this circus of lies and arrogance. This old codger is through with the parade, and done wearing masks.

Hey /sci/ a friend of mine who is not good at math signed up for statistics honors. I have no idea what they were thinking, but here's a problem they can't figure out. I've never taken stat so if you know of any resources on how to solve this or send me on my way to solving it, or if you could just explain what needs to be done, or if you know of example problems that,d be great. Ideally though I'd rather not bother putting much time into helping them, but they're a good friend of mine.
TLDR: i need some resources so i can teach my friend how to solve this or if you guys want, take a crack at it.
Neuroblastoma, a rare form of malignant tumor, occurs in 11 children in a million so its probability is 0.000011. Four cases of neuroblastoma occurred in Oak Park, Illinois, which had 12,429 children
a_ Assuming that neuroblastoma occurs as usual, find the mean and standard deviation of cases in groups of 12,429 children.
b_ Find the probability of that the number of neuroblastoma cases in a group of 12,429 children is 0 or 1.
c_ Does the cluster of four cases in Oak Park, Illinois, appear to be attributable to random chance? Why or Why not?
I'll delete the thread as soon as i get what I need.

just curious... would a student walkout to the bathroom... (sans hall pass of course) in synchrony at 12:12:12 on 12-12-12 to the restrooms, to flush all things flushable, aka toilets and urinals and sinks and basically anything plumbing related, cause a disturbance in said plumbing system? Just a thought,,,
