  In organic chemistry, there’s a concept called delocalized pi orbitals. The exact reason why it works is complicated and outside the scope of organic chemistry, so I’m not sure if I can really explain it anyways. But the takeaway is that when you see a double bond, single bond, double bond pattern, that generally indicates that the bonds are actually being shared across the entire motif. ie, it’s not really a double bond, it’s more like… a 1.5-bond.

  Having the bonds be shared across multiple atoms gives that region of the molecule special properties, the primary of which is that it tends to be really stable. The reason for that is that any disruption toward that region (eg, adding an electron) gets distributed across the motif, so that each atom is only minorly disturbed.

  And the bigger the motif is, the more stable the region is because it’s able to distribute disturbances better.

  Benzene (the hexagon motif circled) is made exclusively of this double bond, single bond, double bond motif. And as a result, it’s well known for being extremely difficult to modify or destroy. You really have to jump through hoops to do any sort of organic chemistry with benzenes. The motif circled in testosterone still has delocalized pi orbitals, but it’s not as extensive as a benzene, and so it’s less stable

  To summarize: paper got published last year that had this as a figure. It got widely ridiculed because there’s no way that this figure passed peer review. Turns out the reviewers did point it out but the editor ignored it

• ⁨Comment⁩ on ⁨Why is Jury Nullification a Thing, But You Can’t Talk About It in Court?⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  So I can pitch in here. I was a juror on a trial where jury nullification was talked about. Multiple potential jurors did bring up jury nullification and the final jury contained some members who openly stated that they believed in jury nullification.

  The judge and the prosector actually didn’t really care that much - the judge just asked the juror something along the lines of “ok, but do you think you can stay impartial for this trial?”, and if the juror said yes, they were on the jury. And the prosecutor didn’t dismiss anyone.

  My understanding is that both the prosecutor and the defense get 10 freebie dismissals - they can dismiss up to 10 potential jurors for any reason. If the prosecutor wants to maximize the chances of getting a guilty verdict, they may potentially try to use those freebie dismissals to get rid of jurors who know about jury nullification. But it seems like, at least in my case, knowing about it (or even openly stating that you believe in it) doesn’t automatically disqualify you.

  The defense started talking jury nullification halfway through the trial (it was a wild trial), and that was where the judge drew the line. His reasoning was that the it was the judge’s role to instruct the jury on their job and role, so the defense cannot instruct the jury on their own about what to do. So it seems like you can talk about jury nullification, just not if you’re the defendant.

  As for why jury nullification isn’t commonplace, the prosecutor will try to convince the jury that the defendant deserves punishment. It doesn’t matter if you believe in jury nullification if you also believe that the defendant deserves to be in jail. If the prosecutor doesn’t make a convincing argument, then you’d just vote innocent and that’s not really jury nullification. So there’s really quite a long criteria for jury nullification to occur:

  1. The jury knows about and believes in jury nullification
  2. The jury disagrees with a particular law or case but also isn’t emotionally charged enough about it so as to remain impartial
  3. The jury believes that the law was broken, but is also unconvinced that the defendant deserves punishment

  Left over right, then right over left. This creates a proper shoelace knot (aka double slipped square knot). You need to alternate. The alternation creates a self-tightening knot. If you do left over left, left over left (or the other way), then you’ve just done a granny knot, which will fall apart

• ⁨Comment⁩ on ⁨would getting back with an ex be a bad idea?⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  Change isn’t necessarily impossible, but it’s really difficult and requires a huge amount of self discipline - if someone changes, they will be a standout exception rather then the norm. I urge you to consider that someone who ghosts you likely does not value you enough to be willing or able to put in the effort to change. Ghosting is deeply rude to do to anyone, and especially toward your significant other.

  Take my interpretation with a mountain of salt, because I don’t know the full story. But, from what you said, it seems more likely that he reached out to you because you were a convenient backup

• ⁨Comment⁩ on ⁨Further study is needed⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  Your body is made of proteins. In the broadest sense, there are structural proteins and proteins that make important things. Some of the proteins that make things (called enzymes) require additional special molecules in order to function properly. These special molecules are called vitamins. Our bodies can make several vitamins but can’t make several other ones. The ones we can’t make has to be eaten, otherwise the enzyme won’t be able to function properly, and depending on what the enzyme does, you’ll either get sick or die or both. Vitamin C has to be eaten. Vitamin D, our bodies can produce. But the process to make it requires sunlight in order to function.

  TL;DR: our bodies have evolved to force you to touch grass

  1. Not really, no. Love and attraction are different things. You don’t need to be attracted to someone you love.

  2. Unless you find your partner unattractive, I don’t see how sex could meaningfully change

  3. People are good at picking up social cues. That’s probably what you’re referring to. Humans are social creatures, after all. Also, people are trash at picking up social cues, so you’re probably also missing a lot of cues.

  4. That sounds like a really bad idea. Your sense of how common those relationships issues occur is warped. People don’t generally go into relationships trying to exploit someone. You’re going to cause issues (moral, logistical, and practical) with your plan, all because of a concern that’s not likely to happen.

  5. That’s the vast majority of humans. We are a monogamous species, after all. When you see “alpha males” on the internet, just be aware that they’re grifters that want your money. And the best way to make sure you keep giving them money is to make sure that you stay single and unhappy.

  6. Can’t help you there. I can at least tell you that enacting your plan in question 4 is going to lower your chances of finding a wife to 0.

• ⁨Comment⁩ on ⁨Anon is a gamer⁩ ⁨⁨3⁩ ⁨weeks⁩ ago⁩:

  1000-2000 hours in several games. It’s a mix of several reasons:

  1. Some games are more replayable than others. My high-playtime games tend to be roguelikes, played over multiple years

  2. The more you play something, the more of a comfort game it gets. It becomes easier to just play it mindlessly if you just want to turn off your brain

  3. Some games have inconvenient save systems, intentional or otherwise (especially true for roguelikes). This incentivizes you to just leave the game running overnight instead of saving and quitting

• ⁨Comment⁩ on ⁨What's easier to shoot, a bow or a firearm?⁩ ⁨⁨3⁩ ⁨weeks⁩ ago⁩:

  People say assuming with bows is easier? What kind of world do they live in?

  I’ve shot a decent amount of bows and guns, and guns are far easier to shoot. The difference is that because guns are easier to shoot, there’s a greater expectation of accuracy. Shooting a bow at 30 meters and hitting your target is considered accurate, shooting a gun at 30 meters is considered nothing.

  That being said, I still like archery more. There’s just something very personal about the experience of pulling the bowstring and manually making the arrow fly

• ⁨Comment⁩ on ⁨What are the exact ramifications and consequences of the recent meeting with Zelenskyy and Trump/JD?⁩ ⁨⁨3⁩ ⁨weeks⁩ ago⁩:

  Even before Trump and Vance lashed out, it was a shitshow. Every time Zelenskyy brought up security, Trump dismissed it because the the minerals were “more important.”

  European leaders were certainly watching, and their main takeaway was certainly that Trump can and will sacrifice the security of American allies for money.

  Europe and many of the US’s allies had lower military spending and did not to pursue nuclear programs because there was the expectation that the US would help protect these countries. This was exactly the promise that the US gave to Ukraine that got them to give up their nuclear research.

  Now that it’s become clear that the US cannot be relied upon for security, many of the US’s allies are certain to start reconsidering their stance on the military and nuclear weapons. As US soft power crumbles, I expect that new, smaller factions will arise to fill the void, and I expect that China will likely try to expand its influence as well.

• ⁨Comment⁩ on ⁨are "brush" and "blush" really pronounced differently? i pronounce them the same.⁩ ⁨⁨3⁩ ⁨weeks⁩ ago⁩:

  In most native English accents, R is pronounced by curling the tongue very significantly (more than most languages that I’m familiar with). People who aren’t used to this (often people who speak English as a second language) won’t curl their tongues enough, and the partially curled tongue will end up touching the roof of their mouths. This happens to be how you pronounce L, so in these accents, R and L will end up sounding the same.

  Try getting into the habit of curling your tongue more when you pronounce R, and you’ll end up hearing a difference

• ⁨Comment⁩ on ⁨Entropy? Never heard of it.⁩ ⁨⁨5⁩ ⁨weeks⁩ ago⁩:

  I think the intention is that the switch is not going to be immediate, and so there will be a stretch of time where some places use renewable sources of energy and some places still use non-renewables. There’s nothing you can do if your neighbor doesn’t switch, other than to try to capture their carbon output

• ⁨Comment⁩ on ⁨brain blowing orgasms⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  There’s a specific life history strategy called semelparity, which is what you’re describing (breeding once then dying). To my understanding, this is incentivized if the chances of getting a second attempt to breed are too low, and so it becomes more evolutionarily advantageous to simply go all out on the first attempt

• ⁨Comment⁩ on ⁨What determines whether something is small enough to regrow on a mammal?⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  That depends on what you’re referring to. Quick caveat, I’m not an expert in regenerative biology, but I have studied it somewhat.

  The trick is that the healing that you’re referring to, it’s not really healing in the way that you’re imagining it. The skin doesn’t really quite grow back in the same way. Instead, there’s more collagen than there normally would be (we would then call that scar tissue). In essence, we’re not really healing, our bodies are just doing a patchwork fix. The presumed reason is that our bodies figure that it’s not going to cause any problems before we die from other causes. This is really quite true of other tissues as well. The liver is known to be able to grow back, but if you look at the microstructures, the regrown stuff is missing a lot of the nuances that the original had. Our bodies expect us to live 70-ish years, and so they don’t care about anything that could happen after that.

  In order to truly, really regenerate, you’ll need stem cells. Some animals are remarkably good at keeping around stem cells and regenerating, but somewhere along the evolutionary line, mammals lost the ability to use stem cells. It’s still an ongoing area of research about why this happened and whether we can generate stem cells in the lab and whether we can manipulate stem cells to our benefit. It should also be pointed out though that, by its intrinsic nature, stem cells divide and don’t specialize into any roles, so it’s very easy for them to go cancerous. In the few spots where mammals do keep stem cells around, their division is very tightly controlled, and even then they are the source of the most common cancers in humans

• ⁨Comment⁩ on ⁨Any Roguelike/Roguelite suggestions?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  Sounds like you might be into top-down roguelites. Enter the Gungeon, Binding of Isaac, and Nuclear Throne come to mind.

  As for games that I would recommend because I just like them, I would recommend checking out Noita, which is a physics simulation/falling sands roguelite. It’s pretty hit-or-miss, but if you like tinkering, you might like it. I’m also pretty partial towards Crypt of the Necrodancer, which is a rhythm/full roguelike genre mash. The full roguelike nature of the game makes it harder to get into initially but once you get the hang of it, it’s pretty fun

• ⁨Comment⁩ on ⁨If you're not attracted to anyone "in your league", but you cannot choose who you are attracted to, then what are you supposed to do?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  A lot of people here are pointing out the fact that leagues don’t exist, and that is true. But there’s a bigger issue here that’s not being brought up, which is that you’re viewing relationships as mutual infatuation. That’s not what relationships are.

  Love is a conscious choice. You love with your mind, not with your heart. You don’t need to be infatuated with someone to love them. And frankly, I would argue that infatuation is a huge negative in a relationship, because it causes you to make irrational choices that will put strain on the relationship. If you aren’t attracted to your date, the proper thought process should be:

  “That sucks, but it’s not a dealbreaker. Do I feel like I will still be friends with this person after years of living together? After learning all of this person’s bad habits? After being annoyed to hell and back by this person, do I see myself still choosing to value this person?”

  If the answer is yes, then you’ve got yourself a potential partner that you might love.

  Another thing to point out is that physical attraction is very tightly related to the people you’ve been around. It’s not uncommon for someone to find their partner increasingly attractive over time.
