Moment of silence for those who thought environmental science doesn’t have maths. (No money is true though.)
accurate, and for the record, EPA, you can take my DCM wash bottle out of my DEAD DEGREASED HANDS
Like, so what if we store our tBuLi with other low-flash point flammables? And pyrophoric oxidizers? In the same bin? That’s stuck in a block of ice in the 30-year-old freezer because it hasn’t ever been de-iced?
What if the power goes out for a long period of time and the tBuLi goes for a swim? Or we say you have to de-ice the freezer?
Haha sounds crazy. And, I wouldn’t have to do the shitty quench before disposal. Or work on that project anymore.
Because you’re injured or because PI fires you?
Haha, yeah :)

Oh, while you’re here, does this still smell like DCM? I can’t tell if I rotavapped it all off and the NMR tubes all need aqua regia (sorry my b).

That’s just bad management and you shouldn’t store tBuLi that long anyway because it’ll decompose. You shouldn’t put it in freezer either

just put it on high vacuum
What are you working with that requires aqua regia to clean NMR tubes? I’ve only had to use piranha once in a decade, while cleaning things that acetone, DCM, and basic ethanol won’t touch, and this was just after moving to another lab
That’s just bad management / just put it on high vacuum
Yes. The whole thing is satirizing the “Safety -> Against” bit. Each piece, though exaggerated for effect, has a basis in something I’ve seen over the years.
Regarding NMR tubes though, the answer in my old group was precious metal complexes, which have a tendency to mirror out once they’ve done their bit. Or just existed for too long; a lot of them were touchy. The mirror tends to resist solvents and scrubbing. Nitric acid alone sometimes was enough to remove it depending on the metal, but often not. At some point the cost, effort, and danger are all supposed to outweigh just binning the lot and buying new tubes, but my PI was allergic to buying new things.
Aqua regia isn’t even that scary. Try pipetting pure bromine while it shoots itself out from constantly evaporating
Aqua regia ain’t no piranha, and also ain’t the most concerning thing in my post lol.
Ah bromine. Super dense, low MW, and low bp, all making dosing accurate amounts a heroic feat. If you store your bromine cold, you can precool the pipette by sucking up and spitting out a few times before transfering, which helps cut down the vapor.
When I find a solvent on pubchem that has the taste characterized by some mad lad from the 1800s, it makes me want to try it.
You say THF is spicy water? Now I’m curious. We must confirm this claim.
I hear ether smells good. We must confirm this claim.
These fancy new box cutters are safe and cannot cut your hand. We must confirm this claim.
There could be one more to differentiate engineers from architects. Do you like to solve problems (engineer) or create them (architect)? Fun flowchart!
“Frickin’ beautiful.”
It got me
You know it’s a complete and proper list because it excludes that pseudo-science Geology.
After indirect
Do you want to feel like you are in a secret society? Yes -> actuarial sciences
Did you try any of these and not like it? Yes -> geology
Economics is STEM???
Yes. In the heirarchy of science, it ranks just below literature.
Well, whilst it’s basically Astrology, it does decorate itself heavily with Mathematics.
(A more serious answer is: it depends on which part within Economics one is talking about. For example Behavioural Economics does use the Scientific Method).
Econometrics, data science, behavioural economics, game theory, micro and macroeconomics, public policy, all of it uses the scientific method and is empirical.
Could you clarify which part of economics you believe is not scientific?
First, Game Theory is from Mathematics, not Economics.
Next, Policy Making is Politics, not Economics. Sure, many Economists end up working in it, but I wouldn’t actually blame Economics for all the Conclusion-Driven Model Crafting that goes on in there - that abuse of Mathematics and modelling to overwhelm and swindle “people who aren’t good at maths” is a perversion of even Economics.
As for the rest, the lack of reliability of central bank forecasts of thing such as GDP Growth and Inflation would indicate that whatever they used to base their forecasts on isn’t reliable enough for publishing.
As the saying goes, Economists have predicted 8 of the last 2 Recessions.
Back in the day when I worked in Finance and followed those things, it was quite extraordinary just how much of that was flipped around and re-explained when the final numbers came out and things turned out to be very different from earlier forecasts.
More in general a lot, if not most, of Macroeconomics does not seem to be Falsifiable: whenever the mathematical models created based on the various theories in Macroeconomics fail to predict what happens (often by a huge distance) it’s invariably blamed on “unexpected factors” - if “unexpected factors” are making your models fail by a huge distance you don’t really have a theory that explains reality and are really just practicing what’s at best semi-guided guessing, same as how in the old days people predicted the weather for the next day by the color of the sunset and how much the bones of old sailors were hurting.
You could literally apply this nonsensical logic to any other field that uses maths and say “it’s mathematics, not X”. This is a non-argument.
“Policy Making is Politics”, politicians implement policies, but the ones behind the scenes who actually do the math to optimise these policies and advise politicians are economists.
“Conclusion-Driven” this is just plain false. There is an overwhelming amount of empiricism in the economics field.
“Economists have predicted 8 of the last 2 Recessions” … and have learned from these mistakes. These were described and studied in detail in my course, and you then go on to say that macroeconomics do not seem to be falsifiable. Yes there are no ways to ethically have experiments in economics, but there are plenty of workarounds to not being able to experiment. Natural experiments are rare but they do exist, as well as a myriad of other data science methods to derive conclusions from real life scenarios.
Finally, “when I worked in Finance”. Finance is a single field of economics, it does not encompass all there is to learn from economics. There is also a conflation from those who study finance courses that what is taught in economics courses is similar. It isn’t. Economics is a STEM field, while finance is a business field.
None of that makes sense.
You’re literally not using Logic (for example “we are improving” does not logically follow from “we make mistakes”), arguing against the very opposite of what I said, constructing straw-men from things I did not say so that you tear them down and trying to support your claims on one thing by making unsupported claims on a different thing.
That shit is political speech, not analysis.
Learning from mistakes is an improvement. That you’re mad about it doesn’t make it any less true. And clearly you don’t know what straw-men are given I’ve quoted you in my reply.
The claim “they learned from their mistakes” does not follow from “they made mistakes” and hence is not supported by it - for example, it’s quite common for people to make a mistake and then derive the wrong conclusion for why, hence not learning from it. You’re literally ignoring the part I disputed in your original statement (that making mistakes does not always lead to learning from them) and instead addressing something I did not dispute at all (that learning is an improvement) - absolutely, learning is an improvement, shame that “learning from one’s mistakes” is a stated desire on how things should be from Pop Culture (i.e. “you should learn from your mistakes”), rather than an observed and confirmed causal relation that’s always true.
Again, shit that isn’t Logic. You adding a claim of madness for my personality really just drives down the point on that.
As for the straw-man, selective picking of what somebody else wrote (with or without the inclusion of selective quoting) “enriched” by affirmations of your own that go beyond what the other person wrote and are not supported or even implied by it, is literally the most common way to build straw-men.
That is literally the path I took to become an Env. Scientist
Ah, a fellow poor with no hope. How goes it!?
