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.

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.

Who said she’s a mechanical engineer?

RagingRobot,

She probably drives a train

SolarMech,

IIRC they all learn some physics at engineering school. Even the software engineers.

    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.

    BastingChemina, (edited ) in We don't judge here. :)

    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.

    lemmyseikai,

    Wow med school has really upped their game.

    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.

    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.

    Peppycito, in We don't judge here. :)

    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.”

    @oce@jlai.lu avatar

    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,

    usually people consider mathematicians as scientists

    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

    oce,
    @oce@jlai.lu avatar

    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.

    PoisonedPrisonPanda, (edited ) in New WD40 formular just dropped

    Man you got me.

    I was like "wtf this stuff are proteins? "

    But then:

    WD-40’s formula is a trade secret. The original copy of the formula was moved to a secure bank vault in San Diego in 2018.

    To avoid disclosing its composition, the product was not patented in 1953, and the window of opportunity for patenting it has long since closed.

    WD-40’s main ingredients as supplied in aerosol cans, according to the US Material Safety Data Sheet information, and with the CAS numbers interpreted:

    • 45–50% low vapor pressure aliphatic hydrocarbon (isoparaffin)
    • <35% petroleum base oil (non-hazardous heavy paraffins)
    • <25% aliphatic hydrocarbons (same CAS number as the first item, but flammable)
    • 2–3% carbon dioxide (propellant)

    Sourche wikipedia (i know we are here in a science community but its fucking early here)

    Protein folding is wild.
