No OP, we will never find out. Its impossible without actually turning back "time" and going to "see" the singularity before "the big bang".

You really shouldt concern yourself with questions like this. Study some quantum physics and one step at the time fellows.

We'll find out. I'm sure of that. We'll know exactly into perfect undoubtable detail how we came into existence from nothing.

But we won't understand it. Because we have basically retarded caveman brains.

We can figure out stuff that we don't even understand.

Im thinking as the finaly job I want to do one of these

Work in a lab researching and creating new magic potions(medicines)

Work in a lab just synthesising chemicals for someone.Then after that maybe start up my own company supplying some sort of company.


Do something related to leaning about the brain like learning about consciousness creativity emotions ect ect

Hello /chem/

First of all, I am by no means a chemist. I probably know more about chemistry than the average joe because I learned some stuff at a high level high school. This however, does not mean that I really know a lot.
Anyway, I'm planning on doing a food-grade cactus alkaloid extraction soon. I found this one to be very doable, and I've found everything needed to do the extract: http://wiki.dmt-nexus.me/69ron's_D-Limonene_Mescaline_Extraction

However, the only ingredient that I'm afraid I won't be able to obtain, ironically, is the D-Limonene itself. Do you guys know any good alternatives, or should I just stick to obtaining this very ingredient? (I'm in The Netherlands btw, should that matter for product choice)

Look for 'Citrus Turpentine' online/in store/art stores, it's D-limonene.

You could also extract it yourself from orange peels. Says you need 900ml, which is probably 50+ peels.

Hey,
I was looking on Erowids rhodiums archive, and found this interesting alternate synthesis of mescaline:
http://www.erowid.org/archive/rhodium/chemistry/electromesc.txt
Since it's from 1933 I think there's some major improvements possibles.
Any ideas?
>The ester in the solution was then
removed by shaking out once with diethyl ether.
A different solvent maybe?
>after extracting four times with ether
same here
> the amine precipitated with dry hydrochloric acid gas.
Could a concentred aqueous (31%) HCl be used?

Maybe you can precipitate the amine with a rotatory evaporator. A yield of 77.3% is already quie good and all the steps used are standard lab procedure today.

Then again. You could just reduce the nitro group with Fe/HCl and then hydrogenate the double bond using a reducing agent like NaBH4 or some Pd or Pt catalytst that probably wasn't available back in the 30.

1) Could try DCM. Easy to get/distill.
2)DCM again
3)No it can not. Dropping sulfuric acid onto NaCl dampened with aq. HCl will do the trick. The gas produced needs to go through a drying tube (CaCl2) and bubbled into a dried (w/ mgso4) solution of nitrostyrene and organic solvent(DCM or toluene) All of those reagents can be hardware store grade.

So chemists, I've run into a disturbing trend of people taking a ratio of MDMA/cathinones then doing a re-x resulting in crystals which test for MDMA on a Marquis, but have a definite cathinone feel to them. How would one reverse engineer this? To make this little mystery even more exciting, I have no idea which cathinone is being used just that it's of the cathinone family.

They aren't just mixing up the two heterogeneously to gain extra weight, one chunk off a single crystal tests positive for both MDXX/Cathinones. I'm guessing the regular freebase/precip w/ HCl procedure won't work out thanks to their similarity. Perhaps freebasing then distilling? I'm absolutely stumped as to howto separate the two. I'm not asking for a step by step "recipe", just a point in the right direction, I can do my own homework

Column Chromatography bro. That would work best. Also, you form a sodium bisulphite adduct with the cathinone. Ketones react with bisulphites and fall out of solution.

I'm graduating university in October. I now have to decide what goes on my official degree. I majored in microbiology and have a double minor in chemistry/psychology, but I can only officially list one minor on my degree. My first reaction was 'well chemistry obviously'. But then I wondered whether psychology might be considered useful as a 'people' skill by potential employers; ie. a background that isn't encountered often (because scientists typically go 'well chemistry obviously'). I've been in school so long I don't know how jobs work, lol. What do you guys think?

Neuroscience guy here, and I'm going to tell you what's up.
Nobody cares about your minor, everybody studies lots of different subjects in undergrad. The job market for chemistry related careers is worse than the job market for psychology related careers. It really depends what you want to do, I majored in psych with minors in bio and english and now am a grad student in an animal behavior lab. If you want to sit at the bench with a pipet and test tubes and a centrifuge then focus on chem or if you're interested in living things like humans then focus on psych. Get a PhD in specifically the type of stuff that you want to do research in, or if your grades are strong then you could go to med school. MD's are running most life science research projects right now.
Peace and SLAYER everyone.

As much as this thread seemed a bit kindergarden grade, I too would actually like to hijack it to ask how to do some of this.

Not necessarily just "how to use excel" per-se... but annotating things with little arrows like that and stuff.

Like so many times in my course do we have to plot standard curves and then read an f(x)... which is dead easy to do with the line equation and do a calculation... but I'm not sure how to just... plot and present some lines that "show" what I'm looking at short of saving the photo and editting it in photoshop.

Is there some more sophisticated software I can use to do things like that or am I stuck doing things the slow way?

do a scatter plot in excel, change the graph format so there are no bullet points, and go to the formatting options and choose 'smooth' or whatever that function is. I forgot what it's actually called but it smooths out the points so you don't have a jagged peak. Just choose your points wisely so that you get the general shape of what you need

Well, I'd recommend gnuplot. Get a gaussian limited between two points such that it stops at the shape you want, the plot two points on the ends and two points that would make the lines you want. Plot the gaussian and two files with those points with lines and bam, that thing.

Than just use some form of office to add those arrows and then text boxes and all's well with the night's watch.

Could also use the matplotlib library for python.

Or if you want to pirate, origin is great.

I think both of those have tools for annotating with arrows and such. But they're limited in that regard. Much easier annotate in photoshop/GIMP/illustrator/Inkscape/etc.
