I’ve never seen acetone that looks so much like french fries.

If you ask a scientist what pi is, they will tell you it equals 3.14159. If you ask a mathematician, they will tell you pi equals the circumference of a circle divided by its diameter. If you ask an engineer, they will say “about 3, but let’s round it up to 5 to be safe.”

I’d replace scientist to something more precise like physicist because usually people consider mathematicians as scientists even if it depends on definitions.

Peppycito,

Feel free! I actually just googled it because I couldn’t exactly remember it. I’d use contractions too and make it less formal sounding.

Thank you, I feel free now. Go get those other hostages now!

milicent_bystandr,

Yikes!

… Wait, does this mean I can call a historian an artist? Then I’m game.

BigDanishGuy,

You can call them whatever you want, what are they going to do? They’re historians!

milicent_bystandr,

In twenty years time they’ll rip into me on r/askhistorians

Historians are scientists imo. Is that a reference I don’t have?

milicent_bystandr,

Usually (in my experience?) history is one of the ‘humanities’, which are more lumped with arts than sciences.

oce,
@oce@jlai.lu avatar

Yes it usually is, but I think the methodologies for modern history research is very much scientific.

somebody needs to change the lede to

Analytical and Bio-analytical Chemistry- your society journal for rapid production and global viscosity on analytical research

just to raise even more eyebrows.

Ask a physician physicist to build a bridge, it collapse but he knows exactly how and why it collapsed.

Ask an engineer to do it, it holds but he has no idea how it’s holding together.

Hobo,

I think the word you’re looking for is physicist. A physician is a medical doctor (as in a person that treats sick people). A physicist is a person that studies physics (as in a person that knows how to solve word problems involving pool tables).

It’s a classic French speaker mistake because physicist is “physicien” and physician is “médecin”, very different.

    Neither do the physicists

    I_am_10_squirrels,

    I did chemical engineering because it only required two physics courses.

    And because I like chemistry.

    calcopiritus,

    In my engineering school, the major difference between software engineers and real engineers is that software engineers don’t study physics.

    Decoy321, (edited ) in Hmmm... pungent, weakly aromatic!

    I went and looked this up, turns out drinking acetone isn’t as outright dangerous as I expected. Our bodies produce a little of the stuff when breaking down fat, into ketones. It’s only a problem when there’s too much of the stuff for the liver to process.

    So basically it’s like drinking rubbing alcohol.

    … Which you still shouldn’t do.

    I looked up the safety sheet for this meme title ngl.

    ornery_chemist, (edited )

    I don’t think your comment emphasizes enough how like drinking rubbing alcohol drinking acetone would be. Rubbing alcohol (isopropanol) is, in fact, metabolized directly to acetone when ingested. The acetone can be metabolized further, but a good chunk is also simply exhaled.

    LemmyKnowsBest,

    All right then, chemically and metabolically speaking, (this is hypothetical and I never have any intention of drinking rubbing alcohol or acetone), what is the maximum amount of these liquids a person could drink before it becomes dangerous?

    onion,

    There usually isn’t a single point where something goes from safe to dangerous

    ornery_chemist, (edited )

    ¯_(ツ)_/¯ I was just trying to highlight a fun fact about how they act similarly metabolically.

    But since you asked, according to wikipedia, the oral LD50s for acetone and isopropanol (taking average of values for rats, mice, and rabbits) are 4713 and 3655 mg/kg, respectively. Extrapolating to a 75 kg human, that’s 451 and 349 mL for a 50/50 shot at permanent night-night. For comparison, ethanol is ~7300 mg/kg -> 694 mL by the same metric.

    Never have I disagreed with him more. Brassicas are horrid and kale is one of the worst

    eestileib,

    I like cabbage and broccoli and cauliflower but FUCK kale. That’s some nasty shit.

    fireweed,

    I don’t know your life, but are you sure you haven’t just had poorly prepared brassicas? Have you tried roasted Brussels sprouts? Do you hate sauerkraut and coleslaw? Buffalo wing cauliflower? What about mustard (the condiment, the spice, and/or the fresh leaf)?

    There are lots of ways I hate brassicas: kale chips (gag), broccoli of any kind (not even in Chinese takeout), and let’s not forget plain, steamed brassicas (basically medieval dungeon food). But the brassica family is huge and there are so many ways to prepare them. Even kale by itself has dozens of varieties, and they do in fact have different tastes and textures. In fact, the exact same plant will taste completely different depending on time of year: mustard leaves harvested in summer heat are almost unbearably spicy, but nearly lettuce-bland in winter. Kale harvested in summer is way more bitter and earthy than in winter when it’s juicy and sweet (in response to freezing temps the plant produces sugars like an antifreeze for the leaves).

    Saying you hate all brassicas is like saying you hate all nightshades: you may be correct, but it’s such a huge family it’s hard to imagine there’s not something in there you enjoy.

    ReCursing,
    @ReCursing@kbin.social avatar

    I've not tried all of them but I don't like the ones I have tried

    And yes, I have tried roasted sprouts, they were perhaps the worst. The best way I have had sprouts was chiffonaded, steamed, then roasted with bacon and chestnuts, but that would have been so much better without the sprouts. Sprouts are absolutely the worst brassicas (and don't tell me "there's a new cultivar that's less bitter now" cos that's also horrid and the bitterness was never the problem). Kale is tough and nasty, broccoli tastes bad and bits of it get everywhere, cabbage is acceptable raw if it's not too strongly flavoured, or its flavour is hidden behind something else and it just provides a crunch.

    Mustard (English or Dijon) is good, but not American mustard, that stuff is more bland than mayonnaise! But prepared mustard the condiment tastes absolutely nothing like the leafy green crap I mentioned above

    I do like other vegetables, just not brassicas

    fireweed,

    I’m definitely with you re: American (yellow) mustard. It’s good on a street dog in Chicago, but that’s basically the only time I’d eat it.

    Who cares if its not gonna be practical, science funding is good and there are lots of things to be learned even from unsuccessful fusion projects.

    redballooon,

    If you talk billions you gotta chose which science to fund.

    Obonga,

    This is the right answer. Humanity should not stop to be curious simply because it does not turn a profit.

    PresidentCamacho,

    Capitalism is a cancer that destroys the best thing about humanity

    cynar,

    Capitalism is like fire. Let it run free and it will burn your home down, and your family to death. If it’s controlled, and focused however, it will keep them warm, and power your industry.

    Unfortunately, we’ve let capitalism run rampant, and now we need to bring it back under control.

    PresidentCamacho,

    Great analogy, but I cant fully agree. It seems to me that capitalism will almost always act the same way, it will always seek out every manipulation and loophole possible to get money into politics and then its good game. The people will never be able to stay as informed and hardworking at voting for right people and policies, as private money will be at buying the worst candidates and policies. Greed is essentially baked into capitalism.

    …Then again what system wont be broken by the worst parts of humanity given enough time. I feel like the constitution should have been more robust, set out ethical guidelines for the country, it would make it so much harder to be a piece of shit and claim you love America at the same time. Especially as I see nationalism as the final nail in our coffin.

    SuckMyWang,

    This is not capitalisms fault. It’s weak and corrupt leadership. Leaders who care more about people than power and money are required to keep it in check. Last time I looked they were all doing their own thing and I can’t blame them but still, it would be nice.

    PresidentCamacho,

    Except it is capitalisms fault. If the capitalist must make more money each year than it did the year before, eventually the only way to make that happen is by influencing elections to get bills passed that bring up the ladder behind you solidifying your monopoly, or by deregulating the market so you can produce more with less.

    SuckMyWang,

    What you’re describing is not only caused by unchecked greed (solved by strong leadership), it’s lazy capitalism. In actual capitalism the business must achieve constant growth yes, but the part people forget is this is supposed to be achieved through innovation and adaptation. If the businesses fails to do this it goes out of business. Capitalism allows for years of decline so long as the business is strong enough to sustain it. What we’re seeing by companies influencing elections is open admission that they are either struggling to produce innovation or they are greedy. Sometimes probably both. If they are innovating like alphabet or meta and they still do it it’s lazy greed plain and simple. Capitalism ends here, strong leadership should start here and push back against it. You could argue this is where democracy is broken because these companies can control the flow of information and will sway public opinion to vote out a politician that doesn’t play their game. Unfortunately this is still poor leadership. A truely good leader will do their job regardless of public opinion or in the face of losing an election.

    PresidentCamacho,

    I think we disagree on one specific point, I believe weak leadership is a guarantee when massive institutions can no longer grow and instead seek to cheat growth through political action. The vote of the people is meaningless when compared to so much capital. I believe it to be inevitable. Sure strong leadership could prevent this, ,but we elect leadership and are easily manipulated.

    SuckMyWang, (edited )

    Yeh I agree it’s fucking dire. The electing of easily manipulated leadership is the problem. Basically capitalism has hijacked democracy and the only way forward is through selfless leadership. Without it capitalism will probably consume us. You’re probably right that it will but it’s nice to know there’s a solution, better than no solution.
