Hey /sci/. Does anyone know where I can download gaussview for free? Where does /sci/ get its specialist software without paying for it?

what is the highest level of mathematics

decode this. Not that hard, let me know what u thk

Hello guys. I somehow passed my last exam for this year, but there is a thing I still don't understand (probably did it wrong in the exam too). It's about the Euler method. As far as I remember the equation looked like this: > dx/dt - t = 0 I solved it like this: > dx/dt = t > x_0 assumed as given > x_1 = x_0 + ht > x_2 = x_1 + ht = x_0 + ht + ht = x_0 + 2ht > x_3 = x_2 + ht = x_0 + 2ht + ht = x_0 + 3ht > x_4 = x_3 + ht = x_0 + 3ht + ht = x_0 + 4ht >... > x_n = x_(n-1) + ht = x_0 + nht The thing is that > t is an independent variable. I think my calculations would be correct if it was a dependent variable, but it's not. How do I calculate this correctly?

Are brains deterministic the way that computers are? Or do they have something in them to generate entropy for random number generation?

My grandma insists in buying me a good graphing calculator. I think I´m going for the TI-nspire CX CAS, is it a good choice? I have another one to use for tests where programable ones are forbidden so that´s not a problem.

1. I'm having trouble really "getting" what a ?-algebra is versus "an algebra." I have the axioms right here, but I think I really need to work with some examples. Could someone more knowledgeable than I provide some such examples? 2. Where can I get a cheap (mechanical) planimeter?

http://www.extremetech.com/extreme/108573-worlds-first-programmable-quantum-photonic-chip Anybody know how the hell this works? I've been messing around for it a bit but just can't quite figure out the simulator. Sim: http://cnotmz.appspot.com/

You know those basic number sequences you can figure out what the next number should be ie. 4,8,16,32,... I'd like to provide some parameters and see if any one can work this out. You can have 6 numbers 123456 They can be arranged in any order and grouped however you like. 1,23,456 - 12, 34,56, The sequence should have more than two given numbers 123,456 is wrong The next number in the sequence should be 335.

Alright, /sci/entists, what's some cool stuff I can make using materials you could find laying around in the house? I'm talking stuff leaning more towards chemistry, alchemy, that kind of thing. Help me see something cool ro make something that's interesting. I've got a weekend ahead of me and all I really have to do is play Saint's Row IV and watch Breaking Bad. And on a side note, is there anything safe but hallucinogenic you could make with household materials? I've always wanted to hallucinate for a short period of time without almost dying...

I'm an expert on calculus. Ask me anything.

In the US, which one is more difficult to get (lab, years, stress, kissing asses, etc) and which one is more respected by the general public?
