It activates the same chemicals in your brain as cocaine! not-built-for-this

Well, yeah, there are only ~~three~~^[@Neuromancer49@midwest.social corrected me] a few neurotransmitters. That's not saying much.

You know what else activates those chemicals? Practically everything. When scientists breed "knockout" mice without dopamine, the mice just stand there until they die of thirst, because there is no reward for.... living.

It contains more germs than a toilet seat! NOOOOO

Germs like moist surfaces. We don't want germs on our toilets, which is why we make them out of porcelain, which is hard, dry, non-porous, and easy to clean.

If it had more germs than your colon, then I would be concerned.

Yeah, this is just one of those weird occult things that worked its way into common thought

Like, this is why science fiction always has people doing telepathy or telekinesis because humanity was going to """"evolve""" into being able to use more brain

oohhh, I've wondered about that. like huh, why is this form of magic so common in sci-fi?

So, this actually comes from our favorite psuedo-scientific psychologist, Carl Jung. It stems from his idea of the gestalt, or world-conciousness. In a similar way that Freud hypothesized the unconscious and subconscious mind that has radical influences on our behavior, Jung hypothesized an 'over-conciouness' from which all conscious beings draw behaviors from. Jung believed that the gestalt explained why migratory birds who were never raised with others of their kind knew to fly south in the winter, or why all humans have myths about floods and snakes, even when there are no floods or snakes present in their eco-system. It is considered mostly horseshit with some interesting philosophical implications, but it still has a dominating presence in the fictional writing world, with 'The Hero's Journey' story type being created from a student of Jung's.

As for science fiction writers specifically, they were in particular obsessed with the idea that we would eventually be able to evolve to communicate within the gestalt itself, thus being able to communicate through thought alone. This kind of thinking, which slotted neatly in with the previous fictional fad of Spiritualism, which also had these elements, but present within a supernatural context, dominated science fiction writing to the point that most authors don't even really know what they are referencing anymore, as the results of extrapolations on this idea (telepathy, clairvoyance, extra-dimensional beings) are larger than the original idea itself.

Dopamine does a lot in the brain. Much of its function depends on where it's active. When released in the ventral tegmental area, it causes reward and happiness. In the basal ganglia, dopamine helps us coordinate movement.

Since I'm already on my soapbox, I'd like to point out there's more than 3 neurotransmitters. These are the basic ones:

  • Dopamine - reward and muscle movement
  • Acetylcholine - motor neurotransmitter
  • Glutamate - primary excitation transmitter, important for memory and overall function
  • GABA - primary inhibitor transmitter
  • Glycine - inhibitor in the spinal cord
  • Serotonin - the other happy hormone, involved in a lot of complex stuff like sleep, depression, and hunger
  • Norepinephrine - fight or flight, adrenaline
  • Epinephrine - the other fight or flight hormone
  • Oxytocin - the nipple clamp hormone

https://en.wikipedia.org/wiki/Neurotransmitter?wprov=sfla1

[–] 7bicycles@hexbear.net 29 points 1 month ago (3 children)

Oxytocin - the nipple clamp hormone

obviously. But for the people who don't know this, unlike me, maybe you could explainm this one

[–] Neuromancer49@midwest.social 23 points 1 month ago (1 children)

no, it's fine, as I am a scholar. But I am also a communist, and as such I think of the poor and uneducated a lot. I think your comic will help them. Not me though, I knew this.

Breastfeeding babies. Moms get a happy hormone from it.

[–] GiorgioBoymoder@hexbear.net 12 points 1 month ago

direct from wikipedia

Oxytocin is a peptide hormone and neuropeptide normally produced in the hypothalamus and released by the posterior pituitary.[3] Present in animals since early stages of evolution, in humans it plays roles in behavior that include social bonding, love, reproduction, childbirth, and the period after childbirth.[4][5][6][7] Oxytocin is released into the bloodstream as a hormone in response to sexual activity and during childbirth.[8][9] It is also available in pharmaceutical form. In either form, oxytocin stimulates uterine contractions to speed up the process of childbirth.

In its natural form, it also plays a role in maternal bonding and milk production.[9][10] Production and secretion of oxytocin is controlled by a positive feedback mechanism, where its initial release stimulates production and release of further oxytocin. For example, when oxytocin is released during a contraction of the uterus at the start of childbirth, this stimulates production and release of more oxytocin and an increase in the intensity and frequency of contractions. This process compounds in intensity and frequency and continues until the triggering activity ceases. A similar process takes place during lactation and during sexual activity.

The one that annoys me is in astronomy when someone describes a star as being X times the size of the Sun. Diameter? Volume? Mass? What's being compared here?

[–] OnceUponATimeInWeHo@hexbear.net 15 points 1 month ago (1 children)

I always assumed volume, def not mass, but what is it actually?

Scientists don't know how something something

usually they have at least 2-3 plausible theories, and they just can't make or design an experiment which will eliminate the wrong ones. Moreover, even having one theory doesn't mean they know-know (tm) something, at least not in the sense of knowing the truth, they have a model which fits all the currently known outcomes/experiments, which might be the truth. It creates distorted image of scientific knowledge as something absolute, which seemingly implodes every century, instead of a process

(e.g. maxwell derived his equations thinking aether was an actually existing thing (and the equations reflect it), the equations are still fucking stellar 150 years later, aether was thrown out in 50)

*obviously, one can take this to absurdity by saying science doesn't know shit, let me roll coal or whatever the fuck, but i still think nuanced understanding of science would be more positive, with having gradations of "not knowing" and "knowing" over both ontological truth and predictive truth, while the former is elusive and slowly approaching reality (in some philosophies), the latter is likely in firmly "knowing" category

[–] revolut1917@hexbear.net 10 points 1 month ago (1 children)

also scientists basically love it when current science can't explain something bc it means they can debate and design experiments and try to coax out new theories of how the world works. like the Hubble tension. Dumbasses will be like "omg arrogant scientists are ignoring this huge hole in their theory about the origin of the universe", but actually most cosmologists would be sorely disappointed if it turns out their current theories of the Big Bang can explain it after all and there isn't new physics to be discovered there.

I despise understanding physics. Should have never chosen that shit for my undergrad. Pop science, sci-fi, and most movies are just miserable to watch the moment they bring up physics in any capacity. Granted I do history now and it isn't much better.

I HATE UNDERSTANDING

[–] TankieTanuki@hexbear.net 11 points 1 month ago* (last edited 1 month ago)

The physics in The Expanse is far better than the average sci-fi show, but even they believe that blowing up an orbiting satellite will make it immediately rain down onto the planet's (or moon's) surface like an airplane that's lost lift, instead of simply turning into orbital debris. meow-tableflip

“Germ” is also a vague term as it can cover practically any single-celled organism or virus. But all of those aren’t necessarily bad for humans. So a light switch might have as many germs on it as a toilet seat, but they’re not going to be the same kind of germs.

They did the toilet seat one on mythbusters. Iirc a kitchen sink had far more bacteria than a toilet seat, but the sink bacteria was mostly harmless while the toilet had some harmful bacteria.

The word "hypersonic" and "hypersonic weapon", or "impossible to intercept hypersonic missiles", used in pop science publications and news reports. No one knows what this means, and just thinks that any ballistic missile is a hypersonic weapon that's impossible to stop, which is not the case. The US and the Soviet Union hit hypersonic speeds with ballistic missiles in the late 1940s based on V-2 missiles captured from Nazi Germany. The Bell X-15 was a manned hypersonic rocket aircraft in the 1960s. The US deployed maneuverable medium range ballistic missiles capable of hypersonic speeds in the Pershing-II in the 1980s. The Soviet Union had mass produced air launched ballistic missiles capable of hypersonic speeds, the Kh-15. None of these were considered hypersonic weapons. And none of their modern day contemporaries, like the Russian Kinzhal or maneuverable Iranian ballistic missiles, are technically hypersonic weapons. That doesn't mean that they're bad weapons systems (in some use cases they are superior to hypersonic weapons), just not in the hypersonic class.

Hypersonic weapons aren't just about speed, but a class of weapon, to do with achieving hypersonic speeds within the earth's atmosphere on a non ballistic trajectory for the majority of their flight. Such as the Russian Zircon hypersonic cruise missile, US Dark Eagle hypersonic glide vehicle, China's DF-17/DF-ZF hypersonic glide vehicle. It's about flying within the atmosphere at hypersonic speeds.
