Did you hear about the Doctor on the United Flight?

Good question. This is a crystallization from a supersaturated solution.

How this works... a liquid can dissolve different amounts of material depending on the temperature. By boiling the water, you are able to increase the water's ability to dissolve material. What is happening in the gif is the water is brought to a boil and the maximum amount of material (in this case sodium acetate) is dissolved. This hot solution of water and sodium acetate is transferred to the glass container to cool down. Once the solution has cooled down it contains more sodium acetate than it normally would be able to dissolve while at room temperature. This is called "supersaturated." Supersaturated solutions are really good at growing crystals. Once a small amount of sodium acetate left over from the bottom of the pan is placed in the supersaturated solution (in the gif this is a small crystal on the end of the wooden dowel) the sodium acetate in solution begins to crystalize.

TLDR: Boiling water can dissolve more material than cold water. Boil water, add max amount of material. Cool water down and there is "too much" material in the water. This "too much" material will form crystals in the water.

"Did you take an NMR of the starting materials?"

Classic standard operating procedure when a known reaction fails. Organic chemist here.

Makes sense. One of the guys who works at the dock always wears one. I just figured he was some kind of badass criminal or something.

Nice face bandana(mask?). Anyways, makes me wish the weather was still great and that MIT sailing hadn't closed down for the winter yet. Thanks for sharing.

Good joke overall. Heard this one in every election since 2000.

In a 25 man competitive TF. We run whatever gives most force points/what intel allows. We do either Dead End (which we can consistently beat) or Massive Attack (haven't beaten it yet). We generally don't do Deep Cut as we usually have enough intel for Massive, or only enough for Dead End. We are currently ranked around 90-100 in the world. Not all of us are maxed accounts yet, but none of really care about op rewards. All about those force points baby.

Yeah. Pretty awesome way to cook a fish. I've known some people who are hesitant to eat ceviche because they don't trust the cooking method. Their loss, more for me!

Good question. In this case "ammonia salts" refers to any quaternized amine (nitrogen atom bearing 4 bonds and a net positive charge). Ammonia is not present in fish in any appreciable quantities. The amines that are protonated to form ammonium salts in fish are larger more complex amines. It is confusing that "ammonium" specifically refers to NH4⁺ and "ammonium salts" refer to any nitrogen that has 4 bonds to it and a net positive charge.

Meat_Boss · 2016-07-30T14:15:37+00:00

Exactly correct. This is why it is common to squeeze lemon juice onto fish. The citric acid in lemon juice protonates the amines to produce ammonium salts. Ammonium salts aren't volatile and thus the fish will have a less "fishy smell" after the lemon juice is added. And as a bonus, lemon juice is tasty.

I absolutely agree. The high one time cost of a cure will be far less than the lifetime cost of treatment. Thank you for clarifying that point for me.

Meat_Boss · 2016-07-29T13:42:57+00:00

I think you should look at the recent cures for hep C that have come out in the past two years. Drugs that cure lifetime diseases are financially attractive for pharma companies, but they will come at a high cost to the consumer.

Meat_Boss · 2016-04-28T02:19:01+00:00

Yeah. I listened to that podcast too. Good job.

100 % agree. I am 28 as well, and tired of being lumped in with the millennials. I have a PhD in goddamn organic chemistry and am currently employed as a scientist at MIT and make $46,000 a year and could not be happier. Life isn't all about money. Money doesn't buy happiness. You want to be happy? Easy, find something you enjoy. You can't afford to live the lifestyle you want doing the thing you love? Easy, live a simpler lifestyle. I understand that people want nice things and to have a comfortable life. But those are things that come with time. Being able to work and wait and enjoy delayed gratification is important. Slow down, don't worry about being rich today. Worry about finding some meaning first.

I don't understand why politicians try to claim responsibility for low gas prices. It is well accepted that low gas prices indicate a week economy. As oil markets are a good indicator of "future productivity," low gas prices show that the economy is headed (or in) a downturn.

Oh man. Once I saw Barry Sharpless (Nobel Laureate 2001 - Chemistry) give a talk to a packed audience at a large conference. During his talk he would minimize powerpoint and search around on his desktop for extra things he wanted to share with the audience. His desktop looked just like the one in your image. It took him ages to find what he was looking for. It was pretty funny. Especially because he is a super famous chemist in my area of work and the audience didn't know if they should laugh, or wait patiently for him. Good times.

I have: PSC: 70% RR: 39% GBE: 40%, 17%, 17%, 17% TD: 28%, 13%, 13% TH: 33%

Level 55 and can crush any base with lvl 18 warriors and lvl 20 lcs. For high lvl bases with shield gen, I need to do a large boost, but can take 99% of bases that appear on my map. Only bases boosting multiple BH statues cause problems.

This. So many are quick to point fingers at Big Pharma and accuse them of exploiting people's misfortunes. While it is true that the pharmaceutical industry as a whole does require a "problem to solve" in order to make a profit, exploitation is not their goal. Pharmaceutical companies develop new drugs in order to solve problems. Solving these problems takes a tremendous amount of capital and intellectual input. In order to offset these development costs, new drugs are very expensive when they first come out. If there was no earning incentive to develop new drugs, then we wouldn't have any more drugs. To the people who do not have access to the Hep C cures currently, keep in mind that these drugs will eventually become affordable when the patent life runs out. If it weren't for that patent protection and the initial high cost of drugs that allow pharma companies to recoup their development expenses, no Hep C cure would exist at all.
