Hey /sci/, do any of you know where I can find the"MYRIAD Mathematical Library". It's a torrent with about 1500 math textbooks. Been looking everywhere for it, haven't found a good one.

Probability and statistics are fields of math. Everyday, the events that unfold in your life, to many, can be considered a result of chance. At a given moment, any event can occur, of course, depending on many many variables. So it becomes hard to predict, and even futile to even try to predict. However, math is everywhere. We can see patterns and systems and work them out to expect a result given specific circumstances. So my question is this - every time I create a thread of make a post, what are the chances that i will get dubs, or hell, even trips?

Matrix notation. Which one is correct? My math prof at uni uses left, but I have seen right used often.

Protandim. How much bullshit is nrf2 synergizers? Can I get actual scientific rebuttals http://en.wikipedia.org/wiki/Protandim wiki page for those mildly interested.

Probability

Hi /sci/ Lately I've been having some fun at the casino and I've been trying out a bunch of different strategies to try and get an edge. (I realise it's stupid but it's just a bit of fun so hear me out). If you're familiar with roulette you'll know there's 37 numbers (18 red, 18 black and 1 green). I'm trying to figure out the probability of NOT ROLLING RED 6 times in a row ever in 100 spins. Firstly, the probability of rolling red is 18/37 = 48.65% So the probability of not rolling red is 19/37 = 51.35% The reason I wish to know this is because I'm fascinated by the 'Martingale' method of betting whereby you double up on your losses, but I want to know the actual probability of losing. By the way, the answer is not simply 0.5135 * 0.5135 * 0.5135 * 0.5135 * 0.5135 * 0.5135 = 1.83% because that is the probability that red won't come up 6 times in a row. I want to calculate the probability that it will happen over 100 (or 1000 or whatever) number of spins, but I have no idea how to do this.

mathematica vs. matlab

44 more posts in this thread. [Missing image file: _MATLAB.gif]
what should I learn, mathematica or matlab? (or other options) I'm studying physics and I recently got a small investigation project that requires any of these. Haven't talked yet to the professor so I'm not certain how's it going to be. I just know it's about chemical reactions and that it's recommended knowledge in any of these. I know python, if it matters, and next semester I'm taking a C++ course, so if any of these is similar / can help each other that would be nice. Maybe I can convince the professor to let me use one of these languages? does that make any sense? Also, I'm using GNU+Linux, so compatibility would be nice. Welp, I'm pirating anyway.

Why haven't plants evolved legs or the ability to travel so they can move around to locations where they can get more sunlight / better soil / less danger?

Is it as good as it's supposed to be? Can you really learn high level mathematics? Share your opinion, tell the topics in khan academy that are very well explained and those that are not so well.

What are some hot-button issues in science? It doesn't matter what branch or type of science. It can be a method, it can be a concept. Whatever. It just needs to have smart men with fancy degrees getting angry and calling each other stupid without the scientific community as a whole backing either side. I just LOVE controversy.

If 1+1 actually equalled 3 and we had been tricked by the illuminati into thinking it was 2. Then would all our mathematical discoveries and theorems be wrong?

ITT: textbooks that we bought just to look (pseudo)intellectual with them on the bookshelf, while having no chance at all on understanding whatever is written inside.

Tomorrow I will be at an observatory with a Meade LX200 12" Telescope from EST 21:00 to 25:00 near Lat 44, Long -70. Wat do? > Knows next to nothing about astronomy Oh yeah, taking pics. Will post what I get. Anything /sci/ wants to see?

I'm smart too. I know big words, like Socialism and anti-semite. effZfo declined I don't know exactly know what these mean, but they sound fancy.

Everything that exists, will ever exist and has ever existed came from absolutely nothing. Nothing, that is, being an extant idea itself which allows everything to exist simply by nothing being a medium containing the potential of all existence. Further, that the universe is purely an idea underpinned by logic and more specifically, mathematics. In fact, the concept of everything coming from nothing being mathematically simple to explain as 1-1=0, where you can arbitrarily derive any quantity, to infinity, simply negate it and get 0, i.e. nothing. You can thus further extrapolate this to include more complexity ( ((2+3)-1)+6-(5x2)=0 ) and even manipulate it to include several functions and so on where you create a well-defined mathematical simulation of our entire universe. This holds true not just for our universe, but all possible universes, and that all universes which are logically possible also actually exist as well. And finally, that all of these universes exist merely from the potential of their logical/mathematical possibility to exist.

Psychedelics - incredibly beneficial substances that can be used as tools for expanding consciousness, solving problems, making novel art, and a lot more. Big names who have admitted that their Psy-drug-use played a big roll in their career: >Dr.Karry Mulis - Nobel Prize winner (chemistry) >Francis Crick - co-discoverer of the structure of the DNA molecule >Richard Feynman - quantum electrodynamics >Steve Jobs >Bill Gates Before dismissing this and say this is all hippie bullshit, take a look at this video with an open mind:http://www.youtube.com/watch?v=3shL389L2EY Discuss

You know what? I'm tired of physics, it's not fascinating, it's boring shit about calculating stuff all the time and replacing it in formulas, that's not interesting. Math on the other hand is way more fascinating, it a lot more than just calculate shit, it's way more beautiful and you have to actually think and not just follow steps and calculate all you can so you can see what you can do with those results. That's it, I'm switching to math.

Just took 20mg of hydrocodone. Any advice for a nice relaxing night? I got some lorazepam and wondering if I should take some as well if anyone has had experience with that. Also been listening to Blackmill and I'm trying to find some similar artists if anyone has some suggestions.
