Physics Vs Chemistry by Nicholas Clayridge - Sat, 20 Dec 2014 01:29:51 EST ID:iSJN1igQ No.75897 Ignore Report Reply Quick Reply

Don't mind the picture.

So this is my currently dilemma. I've recently gotten my life together and will hopefully be returning to college this fall with chemistry as my declared major. However I have a yearning for physics mostly due to the intense mathematics required and to gain a better understanding of how the world works around me. With chemistry though actually manipulating matter and getting to see my work before me is appealing plus I've always wanted to work in a laboratory setting.

So I guess what I'd like to discuss is others experiences and background in both fields? It is to my understanding that a physicist can have a higher income but requires a master or phd to really be worth while, where I believe as a chemist a BA might be sufficient. Plus demand for physicist should be rising for the years to come while demand for a chemist would stay the same roughly.

Kinda late considering how long this thread has been here for.
Math is probably the worst decision in terms of money. Also grade school is pretty much mandatory if you want to be anything other than a grade school teacher (okay there are a few jobs out there with a bs in math but there's a very good chance you'll end up teaching).

Engineering is probably the best choice for the money. Also the best if you don't want to go to grad school. Your pretty much guaranteed a job. Not many profession are like that. You can take a math minor too if you want. Not that uncommon for engineers (you'll take most of the same lower level math). Or a phys or a chem. Or Dual major with math/phys/chem. Dual majors don't really offer that much more in terms of employment though.

A bs in chem will probably get you a job. Not guaranteed but likely. Go for the acs (or whatever it's called) certification. A ba is even less likely. You probably wouldn't end up doing anything too exciting. A ms/phd will open up a lot of doors. If you into math phys you can specialize in physical chemistry in grad school. Your now qualified to more than just a lab grant work.

A bs in physics I'm not as sure about. I've heard some physicists can get some jobs similar to engineers but I'm not sure how true this is. Grad school is probably going to be necessary. I've heard of people doing a dual major in phys/chem but, this is really for intellectual curiosity than helping in getting a job.

To answer you question, more math is good. All four degrees will require at least cal. 3. Taking differential equations and linear algebra be helpful even for a chemist. If your still not sure even you can take a general semester consisting of a math phys and chem class (plus whatever else you want). This wouldn't really slow you down in the scheme of thing not matter what you decide.

i made this thread on /other/ but this seems a more appropriate place

I got a shitton of pure chloroform, alcohol and ether. I'd like to know what are the best and safest ratios to make an A.C.E. mix for recreational uses, as it seems that there are a lot of formulas. In addition, what do you think about adding essences to it and what would be nice ones? Thanks in advance

I looked up the wikipedia page on chloroform, and the part where it says part of the chloroform is metabolized into phosphogene cites this book. I thought that's where you picked up that info aswell. i didn't find the book either.

i wasn't planning to do this exactly for historical reasons. it's simply a rather popular drug used in my country, i tried it a bit when i was a teenager, now i got access to the substances used in it and simply thought it would be way safer to make my own (since god only knows what the fuck those dumbass drug dealers mix in it) and maybe make some bucks out of it aswell. when i searched deeper, i found out the stuff is similar to the A.C.E. mixture (besides the alcohol). since alcohol makes the whole thing safer for use, apparently, i decided to go with that.

just to let you know, it might interest you
a few decades back then, huffing ethyl chloride was extremely popular in my country. it was so fucking legal they handed out that stuff to little kids in parties. after it got banned, people still wanted it but that shit is not easy to bottle or ti produce, it needs too much infrasctructure to do so as it boils at atmospheric pressure, like a hairspray. so, it seems people started selling C.E. mixture telling people it was ethyl chloride (while C.E. is way, waaay more toxic than ethyl chloride), and that's how huffing C.E. got popular around here. pretty funny huh.

Hi /chem/,

Soo, I've come up with a mid week project, Caffeine 'shards'.

I've got meth shards, I've got MSM shards, I've got Ethyphenidate shards but I'm yet to come across caffeine HCL much less 'glass' caffeine, admittedly because it's stupid, but I see an opportunity for some learning and fun here.

Soo, I have 100g of caffeine Anhydrous to fuck about with, and various ml conical flasks, thermometer and an electric stove.

I've been looking at pubmeds, youtube vids and forum posts on re-crystallization (in this case anhydrous to HCL) but really, until I get hands on, it all means vary little.

So any suggestions on temperatures, solvents to use, if it's possible to color the crystals, how to effect density, size, transparency.

Big thanks in advance mah jolly african-americans. I see some fun sience shit ahead.

To be clear I'm not wanting to do this to cut meth, nor do I intend to use made crystals, I got better drugs this is for fun and education

What have you found so far? post links.

Generally, you don't need to worry about temps. You heat until it boils, then you cool it slowly, to as cold as you can.

If I were in a lab, I'm sure some hexane/ethyl acetate mixture would do the trick. For DIY solvents, naptha or acetone might be good. These are guesses though, the surest bet is to find what someone else did.

You might be able to color them, but impurities effect crystal size. So don't bother until you know you can get a good size.

Density you can't effect.

Size is basically a function of how slowly you cool it. There's other factors, like the concentration of the solution.

Just because something can crystalize doesn't mean you'll be able to get big crystals. I bet you can at least get some glittery shit, but IDK about "shards". I really don't know, though. You could certainly try. Like I said, post links to what you have so far. Preferably papers. Google scholar is better than pubmed for this, and use libgen.org to get any papers you want access to. If you can't find anything good, I can search for ya.

I'm going to try to explain this as best as I can.
A while back, I was using a small hand mirror to look at the back of my head. I used the hand mirror, and with my back turned to a bathroom mirror, I looked at the reflection of the back of my head using the hand mirror.
What I found interesting was that WITHOUT my glasses on, I was able to see the back of my head, but it was very blurry.
However, WITH the mirror, the reflection of the back of my head was clear.
I also found that without my glasses, the closer I got to the mirror (with my back still turned, and still looking into the hand mirror) the clearer the image became.
This has me interested because, I'm not looking at the bathroom mirror's reflection, I'm looking at a reflection of THAT reflection, and the reflection that I'm looking at is much closer to my face. Why is it that the distance between the two effects my ability to clearly see it?

Sorry if this is a dumb question, or if this is the wrong board, but I'm legitimately curious.

So, my bathroom is only so big, and I couldn't step away that far. But I DID noticed that even with my glasses on, the farther I got from the bathroom mirror, the more blurry the image became.

Yeah, it sounds like one of the mirrors is ever so slightly concave. The reason two mirrors helps bring it into focus is that it doubles the length of the path. put it on a level surface, then put a bearing on its edge. If it always rolls towards the center, it's concave.

I know some people who think wind turbines are the ugliest fucking things in the world. Obviously rich landowners can pull the "not in my backyard" card, because they're rich landowners. But seriously, we're surrounded by ugly infrastructure. Power lines, antennas, miles and miles of strip malls and McMansions, and highways, to name some of the most common examples. Most Americans see this shit every day without thinking it's abnormal. We'll get used to wind farms pretty quickly if they become more common, and if they don't become more common, we'll still have to put up with them like we do with the occasional (and far uglier IMO) fossil fuel power plant.

Also, do wind farms really kill birds? I don't feel like researching it. I find it hard to believe, but if so, they certainly can't kill more birds than cars or windows.

Wind farms aren't the most effective way to make electricity, but at least they're clean and cheap.

Buildings, fossil fuel power plants, pesticides and cats kill way more.

It is a problem that needs to be considered when building a wind farm though. For example, you probably shouldn't build one near endangered bird nesting sites.

Anyone have any joy or recommendations for these or other cheap chinese milligram scales? I bought some 0.01g and they didn't move until 39mg. I bought some 0.001g and they worked well once for weighing 25mg, then the second time I come back to use them they have somehow fallen apart (the pan unscrewed itself on the underside and when reattached they just drifted forever despite calibration).

I know you get what you pay for, but I'm not sure I can justify or maintain some very expensive specialist ones and maybe there is a sweet spot for these seemingly junk chinese scales where price:performance comes together?

What I mean to say is that you can't give a child Asperger's as a secondary effect of being a shitty parent. Whether or not you are a good parent, if your child was born with Asperger's than they have Asperger's. I really hope you aren't about to have a kid/already a parent.

i do not agree with your ridiculously pretentious attitude in nearly every single one of your posts over on /opi/, and i do not agree with the absolute bullshit you believe about your 5 year old niece.

when i was 8 years old (grade three) my teachers were telling my parents i was at a grade eleven "reading level" (read several stephen king novels, was up to date on harry potter, etc).

this fact should imply that i was ages ahead of my peers which, in most situations, i was. this doesnt mean i was "extremely bored" and caused me to get bad grades, act out against peers etc... completely contrary actually.. the intellectual superiority over my peers in grade school influenced me to achieve very high marks because the material i was being given was jack fucking shit to what i was capable of at the time..

tl;dr your 5 year old niece is just another retard able to read books at a "higher" reading level than the ones her teachers are prescribing her, and is acting out because she is again, just another retarded 5 year old kid...
