  • I grew up rural too, but in a less conservative area, and… Honestly, it made for some hilarious moments in sex ed.

    I think the crowning moment was in high school health class - at the start of the sex ed unit, they split us up by gender, and had both groups try to draw both reproductive systems as a baseline for what we knew. Both groups did pretry well with the male stuff, but there was a stark (and unexpected) difference in the diagrams of the female reproductive system:

    The girls group did an excellent job of drawing and labeling a vagina, but almost none of the internal bits.

    The boys group, though… One dude had noticed something about the general shape of female reproductive system in an earlier class, and came up with a his own mnemonic for it: turns out, you can sketch oit the general layout of the ovaries, fallopian tubes, uterus, and birth canal pretty neatly over the dodge ram logo.









  • I don’t want to be a downer, but… The rats probably aren’t high if they’re just eating weed. Buckle up, y’all, time for a stoner science lesson:

    THC is present in cannabis in two main forms: THCA and Delta-9 THC. Throwing around those delta numbers can seem scary given all of the unregulated Delta-8 in illegal states, but it’s really not. THCA breaks down into Delta-9 THC naturally with time and heat, through a process called decarboxylization… Which is great, because THCA isn’t psychoactive, while Delta-9 THC is. Because of this, smoking a joint or eating a properly made edible will get you high, but eating an entire ounce is just having a terrible salad.


  • That’s actually a really good analogy. Mind if I throw some numbers on it to flesh things out?

    Let’s set that moving walkway going at 5mph, and we’ll put ourselves on that walkway, on a turned-off rascal scooter. The scooter is stationary on the belt, but it’s still moving at 5mph - that’s your tailwind pushing the air around the plane forward.

    Now, let’s turn that scooter on and throttle it up to 5mph. The scooter is plugging along comfortably at 5mph, but it’s actually moving at 10mph. This is your plane flying with a tailwind, performing normally for its indicated air speed, while having a much higher ground speed.

    Curiously, this does make the phrase “supersonic speeds” somewhat debatable. While they were traveling over the ground faster than sound would, they weren’t moving faster than sound would in the air around them.



  • I’m not a scientist, but one could argue that it’s likely that all three planets had nitrogen, but only Earth still has it.

    I don’t know much about Venus, but I know that part of why we have way more atmosphere than Mars is due to Earth’s magnetic field. Earth has a much stronger magnetic field than Mars, and it does a pretty good job of shielding us from the solar wind; meanwhile Mars has been slowly trickling atmosphere into the void for ages because it lacks that shielding.

    Given that CO2 is actually super heavy, it makes sense that Mars would lose almost everything else first. You mentioned H2, but it’s also almost twice as heavy as N2 - because of this, nitrogen would concentrate at higher altitudes, eventually becoming exposed to the solar wind as lighter gases were stripped away.

    As for Venus… Again, I’m not an expert, but a quick search suggests that it has a weak magnetic field as well. With a primarily CO2 atmosphere and a weak magnetic field, one could infer that Venus is in a similar position to Mars, and any significant nitrogen that may have been in its atmosphere has simply been stripped away by the solar wind.


  • I feel like I would use it voluntarily if it put the sponsors in the “add a destination” menu. I tend to use Google maps for longer trips, and I try to add any stops on the way to my route so I don’t miss them - if I hit “add destination” and it offered, for example, Citgo stations, 7-11s, and Dunkin Donuts on my route, then I would probably get gas and snacks at sponsored locations almost every time.

    As it is, though… Well, just having a Dunks on the way to the laundromat doesn’t make me want to stop in and buy a coffee. Driving by ten of them “randomly” on my way to another state isn’t going to make me any more likely to stop at one.
