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.

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?

Help with this chemistry problem? In a experiment to determine how to make sulfur trioxide, a chemist combines 32.0g of sulfur with 50.0 g of oxygen. She finds that she made 80.0g of sulfur trioxide and had 2.0g of left over oxygen. How would the chemist make 100.0 g of sulfur trioxide so that she has no leftovers?

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.
