engineer...

(Curious ask Anon! Thanks for sending it in!!)

Scout: Kinda a jock, but also a loner. The school prankster, everyone in office knows his name, favorite food, and the names of all his siblings (whether or not they go to the same school, or when they come to pick him up)

Engineer: Such a try-hard student, ohmygooooood. Lowest grade was 1 A- in the third grade. Took dozens of math and science classes, and even some after school courses.

Sniper: Such a loner, he would climb up the courtyard trees to eat his food. I like to think he got into tech theater, did set design and backstage work. Average B’s and C’s, fucking terrible in geometry. Saaaaaame.

Soldier: SCREW THE AMERICAN SCHOOLING SYSTEM! He was trained by the ancient teachings of great generals and warriors of the past, and the courage in his heart! (high B’s, so pretty good.)

Demoman: Home-schooled by his parents in the way of Demolitions. Has a knack for the study of quantum physics though.

Medic: Sent to boarding school at a young age, got high marks in science and math. Very much a cookie cutter, quiet kid… he became much more exuberant when he entered Medical school, a lively character.

Pyro: Studied music at Julliard is the new rumor around the base.

Heavy: Loved reading as a child, SAMMMMMMMMMMMME, so immanently began studying to become literary professor, my hero. Got very high scores in Russian and Lit, not so much in the science and math department.

Spy: Private tutors, did everything and anything to get good remarks from them, not excluding bribery or blackmail, the little shite. Was infamous for his undetectable pranks, including the rotten goat cheese he hid in his teachers car for months.

This is what happens when you chat with @marvelthismarvelthat about whether your Fitz holding baby manip or your Skimmons domestic bliss manip is more adorable, and in the end you decide:

anonymous asked:

Hello! If it was the post-apocalypse, would it be realistic for a chemist to ask for uncontaminated samples of 'old world' substances from before the apocalypse—like hair dye, deodorant, etc.—so they could reverse engineer them and synthesize usable facsimiles? What equipment would they need? What sorts of ingredients would be difficult/impossible to obtain/create? Thanks in advance!!

You need to determine three things to reverse-engineer a mix:

  1. The reagents—the what
  2. The amounts—the how much
  3. The procedure—the how

When you’re creating your final product, you need to add things in the right order. Otherwise, your mixture might not mix well, things might precipitate out, you might have a runaway reaction, or any number of other happenings. A chemical analysis might help you with the first two requirements, but that last requirement is something that’d rely on knowledge and wisdom.

Unfortunately, unlike the movies, you can’t just plop your sample onto a scanner and have the computer instantly spit out a perfect analysis of what and how much. Instrumental analysis is not that straightforward:

  • There isn’t One Instrument To Rule Them All—instruments are chosen and calibrated with specific standards based on what you want to analyze. If you have a GCMS (gas chromatography/mass spectrometry) calibrated for quantitative analysis of lightweight VOCs (volatile organic hydrocarbons) and you feed in a sample of heavy PAHs (polycyclic aromatic hydrocarbons), the readout will be nonsensical because it won’t match the calibration standards. Also, the instrument would be contaminated, which will screw up future VOC analyses until it gets flushed and cleaned.
  • You need to prepare your samples—by which I mean you need to turn it into a phase that the instrument can accept. For example, an X-ray diffractometer analyzes minerals ground into a very fine powder, whereas HPLC or MS have samples dissolved into solution.
  • Your samples need to be relatively pure and diluted appropriately. If you simply dilute your hair dye and feed it straight into the instrument without removing the majority of your inactive ingredients, your results will be an absolute mess because there’s too much there. If your sample is beyond the concentration range of the calibration standards, you will not be able to quantify your results. Badly prepared samples could also contaminate the instrument.
  • Molecules don’t always survive a trip through an instrument whole and hale; they often fragment and the readouts reflect that. Also, particular functional groups (fragments) of a molecule often have characteristic ranges on a given instrument’s readouts, but the exact result varies depending on the particular molecule. Your analyst needs to be trained to interpret the results.
  • Finally, a mixture has multiple components. In the case of hair dye, you might care about the actual dyes—i.e. the molecules that would bind to your hair and change its colour. But a sample of hair dye has a lot of other things like thickeners, emollients, oils, pH adjusters, antimicrobial agents, et cetera. If you want to reverse-engineer a complete sample, you’d have to work up your sample, keep all the workup phases, and analyze them each by turn. You may not successfully identify all of the components.

Does that sound like a lot of work? It is.

Going back to your question: what equipment you will need depends on what samples you’re analyzing. In the example of hair dye, I would expect you need to have some common organic solvents, filtration setups, flash chromatography columns, and the glassware required to do some basic workups to separate the organic dyes from the everything-else. You will also need volumetric equipment to dilute your samples with acceptable precision.

Ideally you’d have a fully functioning HPLC (high pressure liquid chromatography) that you can feed the appropriately-diluted sample and it’d separate and analyze all the dyes in the sample for you (I know Agilent has a column that can do this). The silicones common in hair products could probably be identified via GCMS (gas chromatography-mass spectrometry) or FTIR (Fourier transform infrared). Some of the inorganic stuff could probably be identified via ion chromatography. These instruments would need to be set up, supplied with appropriate gases, and calibrated with calibration standards. The samples would need to be prepped, with stabilizing solutions, correct solvents, and internal standards.

Seeing that instrumentation works when the instrument is appropriately chosen and calibrated, such quantitative analysis really only works when you have some idea of what you’re looking for. If you have a blob of red gel and no idea what it is, this may take you a while.

As for what would be difficult to source after the apocalypse…this is really hard for me to answer. It’s reasonable to assume that many chemicals, especially laboratory-grade chemicals (which are graded for high purity), would be hard to source after the apocalypse. However, if you’re at the point where you are able to set up chemical laboratories, then perhaps enough time has passed for industry to sufficiently recover. As a reader, I would accept that you can source the ingredients for hair dye if you’re at the point where you can set up a lab to analyze hair dye; the latter has higher standards of purity.

Now, my question to you: do you have to reproduce this sample of hair dye exactly?

Assuming there’s nothing amazing about this particular sample of hair dye, I don’t think it’s worth the effort to exactly reverse-engineer this sample. Hair dye is also pretty low on the list of priorities after an apocalypse. If we are at the point post-apocalypse where we can think about dyeing our hair, and we have the resources to set up chemistry laboratories correctly and interpret their results, I’m assuming some knowledge from the pre-apocalyptic days survived the apocalypse. Even if the exact formula of your favourite L’Oreal dye didn’t survive, maybe something from Garnier did, and you can simply reproduce whatever you do have and tweak as you go along. Or you might just mix the dyes you do have on hand, add in a bit of antimicrobial agent, and call it a day, even if it doesn’t smell as nice or work as well.

Desperate times, desperate measures and all that.

(How the Mercs got they’re pets, summed up in less then five sentences each)

Scout: Scout caught a squirrel one day. Squirrel has been with him ever since. The Squirrel likes nuts and it sounds like it’s always chucking, hence the name. The End.

Engineer: A barn cat through and through, Ein takes care of all the mice, bugs and Spy’s that come into his work shop.

Sniper: Well, his pet rattlesnake bit him, but as he was slowly dying of poison, he thought that it actually looked kinda cute when it wasn’t trying to kill him. So, after a brief trip to respawn, he adopted the blind rattlesnake, named it Charles and Charles now lives in a bucket.

Soldier: Merasmus! There is raccoons by the pond!” “Leave them be!” *and five minutes later* “Merasmus, I am demoting you down from rank of lieutenant, for you have been replaced… with about eleven others.”

Demoman: He was drunk, shocking, when he first saw Jackie, his terrier puppy. She was pawing at the shop window, so Demo waltz in, traded a grenade, some gum, 83 cents and a bottle of his homemade gin, and walked out with a puppy… Who he forgot about when he woke the next morning with a hangover, and a non-house-trained dog sitting on him. Don’t drink near pet stores, kids!

Medic: The story of his doves are an ongoing case and can’t be discussed with the general public, but he got his white lab mice as a gift when he actually followed medical law. The eight mice he has now are actually the great-great-great-great-great-great-great-great-great-great-great-great grandchildren of his first mice! (Except for Marcellus. He’s adopted, shhh)

Pyro: Well, no one knows exactly what it IS, but apparently it likes raw meat, loves Pyro and it’s illegal in three different countries.

Heavy: Heavy has been collecting fish from every nearby pet-shop he can find. They are beautiful, don’t require much, and are not annoying like whiny cats and Scout. Perfect.

Spy: Spy’s cat is a purebred, black turkish angora , which he… acquired after a job gone sour. The cat is now spoiled rotten, but it’s quite literally a pussycat… It’s terrified of Scout’s squirrel.

 I’ve been dabbling a bit in environment design… 
this scene was built in unreal. I used various other 3d programs to create the assets. 
I still need to figure out a better way unwrap UVs and I’m using 3ds max which is pretty weird with UVs. I’ll probably need to get some scripts that add better UV tools max. In the long run, I might just make the leap to Maya instead.
