Can anyone explain HOW tanning makes a person look more muscular? /fit/ sure as hell couldn't. I haven't really been able to find an answer to this anywhere. Usually, it's just a bunch of imbiciles saying "yeah, it does make you look better" or it "looks healthier.

Does someone has the pdf version of Organic Chemistry: A Biological Approach from Mcmurry? I've searched and I can't find it. If someone could provide a link, I would be very grateful

How can I ensure my mood is happy all the time? For example on day I'll do my favourite things, will enjoy them lots, another I will get no pleasure out of it, just tell me what hormones are causing this and how can I ensure that they are constantly at high levels, because if it's not hormones then I've no idea. No drugs lol.

I would like to pirate mathematica. The latest version I could find was 7.0 while the current version is 8.04. Does anyone know where I could find it since thepiratebay doesn't seem to have it?

Man, I'm fucked. I have a test tomorrow and I need to know: Blackbody Radiation, Photoelectric Effect, Bohr's Hydrogen Atom, Heisenburg Uncertainty Principle, Average energy of molecule, Particle in a box, Eigenvalues, Hamiltonian etc etc... My professor explains these things terribly, can /sci/ recommend me some good videos on these subjects to learn from?

Is this an inside joke?

[rant] I'm close to my breaking point /sci/. I feel like engineering school is just a big joke from the professors standpoint. They give us a shit ton of theory, nobody knows how to do it, we all copy the solutions manual, and then the professor says good job. Test average -> 30/100 Professors comment on the test: "Oh, looks like I made it a little to hard this time." Me in my head: "No fucking shit..." My overall thoughts: Nobody becomes a professor because they are good at teaching. They become a professor because of $$$ and research investments. Honestly, at the end of each school year they should have a standardized test and the professors pay depends on how many kids pass the standard test. At least then I'd get a professor who didn't reuse handwritten slides from 1999. And don't even get me started on the people that write the books... [/rant]

The 'mirror test' is the most fucking retarded, useless, invalid, and pseudoscientific 'experiment' to ever plague science. Partly because not everyone (human or nonhuman animal) will react the same to seeing themselves in a mirror (some won't give a fuck and will ignore it), and partly because not understanding how a mirror works provides absolutely no evidence whatsoever as to lack of consciousness or 'self awareness'. You put a mirror in front of a caveman and at first he will think it's another person, so what if it takes some animal a lot longer than another. TLDR; mirror test is fucking retarded and whoever believes it is a disgrace to science and humanity. Pic related: Clay pot attempting to pass the mirror test.

HELP WITH CHEM SUBMERGING PROBLEM? A 2.03g lead weight, initially at 10.8 degrees Celcius, is submerged in 8.04g of water at 52.8 degrees Celcius in an insulated container. What is the final temperature of both substances at thermal equilibrium?

At what part of your college education is it okay to start thinking about changing majors. I'm on my first term of my sophomore year of college (3 terms per year) and while I did fine in chemistry, math and my chemical engineering courses last year, this year I feel like I don't understand any of it. I've still got the chem down but the Math and chem E work is making me pull my hair out - it seems like nobody in the class knows what to do, but that I'm the only one that actually fails. Anyway, we have midterms next week which will be a benchmark for how I'm doing, and based on my inability to understand or do a lot of the homework due per week, I'm probably not doing very well. I want to know when it's time to give up.

Confessions of a Particle Physicist

7 more posts in this thread. [Missing image file: Lies.gif]
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.

Has anyone here ever had real trouble with a college class before? I'm struggling with Chem103 currently and can't seem to catch up. I got a D+ on the first exam of the semester and have pretty much failed all the mini quizzes my TA gives me. I study the material and do all the homework but for some reason when it comes time to take a test I can't figure things out anymore. I'm considering hiring a tutor but I don't know if that's necessary yet.

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.

So /sci/, why do scientists, when they discover water on other planets, say it must have life or could have life? Why can't planets without water have life, with beings that don't NEED water like we do? This never made sense to me.
