Hey /sci/, can you give me some tips on finding textbook pdf? Ebookee used to be my to-go place but most of the links are dead now. I've been combing google for hours but couldn't find any of my textbook. Can any of you help out a fellow scientist please? -introduction to molecular thermodynamics by hanson and green -The elements of physical chemistry 6th edition by atkins -Quanta, matter and Change - a molecular approach to physical chemistry by Atkins, de Paula and Friedman -Physical Chemistry-A Molecular Approach. McQuarrie and Simon -Molecular Quantum Mechanics. Atkins and Friedman -Biochemistry 3rd by matthews, van holde, appling and anthony-cahill -the organic chemistry of biological pathways by Mcmurry and begley -Advanced organic chemistry by bernard miller 2nd edition These are some of my txtbooks this semester, PLEASE HELP ;_;

How do minimum (alcohol) and maximum (mercury) thermometers work? Here is one definition I found for minimum thermometer: >"The liquid used in minimum thermometer is alcohol in which a dumb-bell-shaped index is set. When the temperature falls, the alcohol column drags the index towards the bulb end but when the temperature rises the alcohol column expands and runs past the index without disturbing it. Thus the end of the index farthest from the bulb gives the lowest temperature attained in a day." How does it drag the index? And why doesn't it move the index when it expands? Is there some kind of animation anywhere. I couldn't find anything on Youtube. -- Maximum thermometer: >"Maximum thermometer is also a mercury-in-glass thermometer having a constriction near the bulb end. When the temperature of air rises, the mercury in the thermometer expands and forces its way into the stem past this constriction. But when the bulb cools none of the mercury above the constriction will get back into the bulb and then the length of the mercury remains the same. The end of the mercury thread farthest from the bulb registers the highest temperature reached in a day." Why can't mercury go back down past the constriction when it cools down? Why is the maximum thermometer slightly tilted? Wouldn't the expanded mercury past the constriction point go back down to constriction point when it cools down?

What's so bad about INFPs?

So, I'm a medical student, but I'm also an INFP, a friend of mine seems to think this means I'm destined to fail at medicine. Why? I'm not sure what the NF means, but my friend was able to explain about perceiving and judging and I already knew about introverted/extroverted. That being said, from what I do understand, I'm introverted, which just means I do a lot of extra-research because I'd rather be doing that than socializing a lot of the time. And if I withhold judgment wouldn't that make me good at diagnosis? My friend does neuroscience, so I tend to trust his opinions on these matters, and looking the type up on Wikipedia it thinks I'd make a great writer which, oddly enough, makes sense to me. I never thought of it as a career path but I genuinely do love to write, just for my own satisfaction. If I don't write anything for a while I tend to get grumpy and/or every other thing I say is some sort of pun. Anyway, before this gets any more self-indulgent, what do you guys think? About personality tests? About my personality (doing the test I scored really high on every factor except I, which was 20, everything else was 60+. I dunno what that means, but maybe someone else does?)

Explain why a polynomial of odd degree must have at least one real zero. This is killing me because I know Descartes' law, and yet I have no idea what the answer to this question is. What is it? A single sentence answer is perfect.

Guys, halp. A cannon fires a cannonball 500.0m downrange at a 45.0 degree angle. At what velocity does the cannonball leave the cannon? This is one a physics review sheet involving a lot of v=d/t type of problems, though most supply the velocity and ask for time. (Easy) I don't understand what to do with this problem, and the answer is already supplied. [70 m/s] I'd prefer to understand how to get to the answer rather that just copy it down, though. Halp Oh, and please define variables in whatever equations and try to make this as clear as possible, please.

An Australian left wing leb commie abbo-loving professor multiculturalist was teaching a class on Mohammed Abderrahman, known Terrorist. "Before the class begins, you must get on your knees and worship Mo and accept that he was the most highly evolved being the world has ever known, even greater than Steve the Irwin!" At this moment, a brave, blue aussie, solidaric pro-white Australia policy TV presenter called Paul Henry who served more than 1500 hours on breakfast TV and fully understood the necessity of VPL for breakfast and fully supported all decisions made by the Australian cricket board stood up and held up a glass bottle. "What's in this bottle, ya big gallah?" The arrogant drongo smirked quite poofily and smugly replied "That is a bottle of Victoria Pale Ale, you bloody wombat". "Wrong. This is the national drink of all Australians, and if towel heads are aussies, then why can't they drink it? The professor was visibly shaken, and dropped his chalk and his copy of the Qu'ran. He stormed out of the room crying those Melbourne anti-aussie tears. The students applauded and all went out to get pissed and go surfing that day. A Kookabura named "Mick Dundee" entered the room and threw a shrimp on the barbie. The professor lost his tenure and was fired the next day. He was killed by an abbo who has been huffing fumes all day and no one even liked him enough to call him a cunt at his funeral. Fuckin' drongo. TLDR: ATHEISTS 0 CHRISTIANS 1

hello /sci/ First off i am not trying to troll, nor am i trying to start some flame war. It is kind of common to mock the religious institution for being backward and just believing something they are told. but when was the last time you actually used the scientific method? when was the last time someone told you something like the sun is getting brighter(pro tip: it is), and you went out and actively looked at the math at looked at the science? Do you understand string theory? Do you believe time to be a dimension? do you hold these beleifs because you went out and researched this (Reading others work counts) or because someone told you? Finally and TL;Dr what is the difference between believing what a scientist tells without research and faith?

Holy fucking shit. Have any ukfags been watching Britain's Brightest? They are trying to find... well, Britain's Brightest. They test things such as "spelling, maths and emotions". WHAT THE SHIT? Many of the contestants are women, despite us knowing that the brightest people are all men. OK, we can expect such a bias from the BBC. Some of the professions of contestants: >nurse >childminder >mother >telemarketer Yeah there was also a maths teacher and physics PHd who did well, but why are the above even in it? The reason for these people becoming contestants are things such as: >good at scrabble >watches TV quiz shows >"I always know the answer to things other people don't" Some of the rounds: >guess people's age >guess people's weight WHAT THE ACTUAL SHIT? Were these literally put in just so women could compete with men? How do they test intelligence? Even the spelling test was silly. The guy who sets the Times crossword puzzle knew all the answers, but lost because they have to do a thing like XBox Kinect and the computer thought he skimmed one of the words with his arm. A TEST OF INTELLIGENCE TO BE SURE. Is this literally the only way they could make intelligence appeal to the masses? By making it stupid and having everyday people on it? Where are the university professors? Are we expected to believe that the most intelligent people in the UK are hidden away having never excelled at anything? These people all believe they are very bright.... Dunning-Kruger much?

/sci/, today was a dark day for science. Aaron Swartz, one of the most brilliant young minds in the country, committed suicide (age 26) after being hounded by U.S. federal prosecutors for his attempts to liberate scientific journal articles which are locked behind paywalls. It's absolutely inexcusable that science articles paid for by public taxpayers is held behind ridiculous paywalls (usually somewhere between $18-$40 to download a single PDF). Aaron's story tells us that in the U.S., profits are put above science. It makes me so furious, I want to do something about it.

I'm intrested in chemistry, biology, physics and math but have a talent for languages, art and all that useless shit which will get you nowhere. I'm currently finishing highschool and would be utterly willing to sacrifice three or more years to specialize in the subjects mentioned above. Where should I begin to reconstruct my life?

Okay, this is what we have so far. We might have a connection between 4220220 and 332 and it's Decatur, Illinois IF we take the first number as a phone number and the second one as an area code.

What are the limitations of building shit in space? Hoe big, assuming you had the resources, could you go before you had structural soundness problems? Are O'Neil cylinder type structures possible?

titrations

I'm currently doing my AH chemistry investigation on a thermometric titration between HCl and NaOH/ CH3COOH and NaOH, and I need to find some decent sources for background theory. Also, in the guide for the experiment, it just says "make graph with results", which is fine, but then it says "find enthalpy of neutralisation", which I am not sure how to do.

Ironically /mu/ is retarded when it comes to this part of music since it deals more with acoustics than aesthetics. Is there any solid argument for the tuning A432 rather than A440? A lot of it is psuedoscience and correlations but I want solid proof
