• ⁨Comment⁩ on ⁨Why are expressions like "women artists" or "women writers" used?⁩ ⁨⁨4⁩ ⁨days⁩ ago⁩:

  That doesn’t really answer why “woman” can be used this way but “man” can’t:

  • Female writer: ✅
  • Woman writer: ✅
  • Male nurse: ✅
  • Man nurse: ❌

  that would kill almost anything else

  Guess what: It’s fact check time!!

  Anthrax: ❌

  Most birds are naturally resistant to anthrax because of their higher body temperature.

  Botulism (actually botox, botulism is the illness caused by botox. You can’t quite eat an illness): ✅

  “Botulism is one of the most toxic substances in the world, and [turkey vultures’] guts are filled with this bacteria, which apparently has no effect on them,” says Graves.

  (Yes, the article made the same mistake)

  Rabies: ❌

  All warm-blooded species, including humans, may become infected with the rabies virus. Birds were first artificially infected with rabies in 1884; however, infected birds are largely, if not wholly, asymptomatic, and recover.

  Cholera (actually avian cholera, which is distinct from “normal” cholera): ❓

  Besides chickens, the disease also concerns turkeys, ducks, geese, raptors, and canaries.

  So 2/4 diseases are already irrelevant for birds but they sound scary because they infect humans. But:

  Avian cholera barely even counts because it’s caused by “Pasteurella multocida” while (human) cholera is caused by “Vibrio cholerae”. The two bacteria are genetically as closely related as humans and mammoths. And avian cholera does not kill anything but birds.

  –

  This isn’t to degrade the vulture’s ability to withstand pathogens and toxins, that is still very impressive. It’s just that obviously birds are immune to most human diseases, as pathogens don’t tend to easily jump between distant species.

  And even if they DO jump between species, they usually do not bring their “deadliness” with them (unless they produce poison like botox) as different species react completely differently. Maybe rabies is the one exception, as adjusting the behavior of your host by rummaging around in the brain has some universally negative side effects.

  Shouldn’t be dangerous, but there’s already less space in that area so it would constrict the walkway unnecessarily.

  Like, looking it up, there seem to be variants wirh seats there but look how little space you have to move if two people are sitting there:

  I don’t see the benefit of having an extra two seats in there compared to just putting in nothing

  Like, being able to speak the very basics I agree. Numbers, hello and goodbye, thank you, etc.

  But “If you can read this, you may come in” is pretty advanced. Like, probably requiring weeks of daily study level advanced to be able to understand.

• ⁨Comment⁩ on ⁨What is negative voltage?⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:

  If you (or anyone else) wants to check their understanding of voltage as the difference between two electric potentials, here’s a couple exercises I stole from a text book:

  (Note: Electric potential is also measured in Volt.)

  A battery has a constant voltage of 1.5V between its plus and its minus pole. What is the electric potential of the minus pole compared to ground potential when:

  1. The battery is on an electrically isolating mat?

  Solution

  The battery is not connected to ground. Therefore, no statements about the electric potential of either pole can be made.

  2. The minus pole is connected to ground?

  Solution

  Because of the connection, the electric potential of the minus pole equals that of the ground, which is by definition 0V.

  3. The plus pole is connected to ground?

  Solution

  Now the potential of the plus pole equals that of the ground. We know that the voltage difference between the plus and minus pole is 1.5V. Since this difference is measured by subtracting the potential of the minus pole from the potential of the plus pole the equation: 1.5V = p_plus - p_minus = 0V - p_minus => p_minus = -1.5V. Therefore the potential of the minus pole is -1.5V.

  4. The plus pole is connected to a generator producing an electric potential of 10,000V compared to ground?

  Solution

  Now the electric potential of the plus pole is also 10,000V. The potential of the minus pole must be 1.5V lower, so it must equal 9998.5V.

• ⁨Comment⁩ on ⁨Is it reasonable to tell a person you once loved about the fact years later?⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:

  Genuinely think you’re arguing about semantics with the love/attraction thing. Like, you can profess your love to someone despite no romantic relationship existing yet.

  It’s honestly irrelevant what term OP uses to describe their feelings.

  Though I do agree with the 2nd paragraph.

  Vinegar?

  Proper pipe cleaning is done using a sodium hydroxide solution. Plus, it causes permanent blindness if it comes in contact with eyes:

  Other common uses of sodium hydroxide include: […]

  • as drain cleaners that convert pipe-clogging fats and grease into soap, which dissolves in water

  Like other corrosive acids and alkalis, a few drops of sodium hydroxide solutions can readily decompose proteins and lipids in living tissues via amide hydrolysis and ester hydrolysis, which consequently cause chemical burns and may induce permanent blindness upon contact with eyes.

  en.wikipedia.org/wiki/Sodium_hydroxide

  It’s genuinely dangerous, don’t handle this stuff if you don’t wear proper eye and skin protection.

  Over here it’s very much a criminal offense, so this only applies to some countries.

  Nope. Assume the chair fits at most C clothes, with C being a constant.

  The efficiency is at worst O© = O(C * 1) = C * O(1) = O(1).

  Sure, the more clothes are on top, the longer it takes. But Big O notation is only useful if the N gets very big. And considering that the naximum amount of clothes is likely very small, it can be treated as O(1).

  Worse: If the chosen axioms are contradictory, then the theorem is effectively worthless.

  And it is impossible to know whether axioms are consistent. You can only prove that they are not.

• ⁨Comment⁩ on ⁨RAMANUJAN SPECIAL⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  Makes sense though.

  The complex Riemann-Zeta function (Zeta(x) = sum from 1 to infinity of 1/n^x) only converges for Re(x) > 1, else it is infinite. We can use analytic continuation - which I understand as extending the function such that it remains holomorphic (basically continuous but in the complex numbers and for some reason well-defined) and find the value of Zeta(-1) that way.

  The value of Zeta(-1) when viewed this way is -1/12.

  It’s not really saying the sum of all natural numbers is equal to -1/12. It’s really just a mathematical trick, just like: lim (x -> 0) x/x = 1 but this doesn’t mean 0/0 = 1.

• ⁨Comment⁩ on ⁨⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  I consider Wikipedia more reliable than vast portions of primary sources. I have seen the awful quality of many papers - “publish or perish” is a thing in science.

  And yes, obviously the label “narcissist” is an insult. Just like calling someone “stupid”. When using it as an insult however, it is clearly meant to say this person displays high amounts of narcissism and behaves like a self-centered asshole.

  This is different to insults such as “autistic” because that is not a personality style but rather a clinical diagnosis. It would be akin to using the term “disabled” as an insult.

  Narcissism is a negative trait if you have too much. That is why it’s an insult. If I say someone is “smelly” I am also insulting their body odor. Doesn’t mean people who struggle with body hygiene for whatever reason should also feel insulted by that.

• ⁨Comment⁩ on ⁨⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  The term narcissist doesn’t just refer to someone with that personality disorder.

  If you are a self-centered asshole, you are a narcissist regardless of an NPD diagnosis.

  See: en.wikipedia.org/wiki/Narcissism

  Narcissism is a self-centered personality style

  Same with calling someone stupid. It doesn’t mean they have a learning disability.

  The rating system isn’t meant to be taken literally though. It’s expected that parents make an informed choice based on the maturity of their child. The ratings are recommendations and as far as I know only actually enforced by stores/sellers and cinemas.
