Uh wow! Mouth dry! Mouth dry!
- Comment on Trying to Help 1 week ago:
I actually watched that episode last night, so that post was kinda jumping at me. What are the odds…
Sagan, a real teacher. Not only smart, there are quite a few smart people. But also able to make something complicated easily understood. To make something abstract sound straight. To make something minds can’t grasp comprehensible. A beautiful ability!
- Comment on Brought my Celestron NexStar 6SE out on a camping trip last weekend and pointed it at the moon 3 weeks ago:
Interesting, thank you for the reply! Learned something new today. The lines I see span over a quarter or so of the moon, so I’m not fully convinced yet. Absolute massive.

Ah, this is probably the right community to ask.
What are those stripes leading to the crater, here in the upper left?
I’ve noticed them before, but when I try looking it up, I usually only find results for Saturn’s moon.
Beautiful picture, op!
- Comment on Who all wants a silent spring? 4 weeks ago:
I recently read somewhere that it’s actually just very few bee species that die after stinging, among them honeybees. They have a barbed stinger that gets stuck while most bees have flat stingers and can sting repeatedly.
- Comment on This mirror is 100 times cheaper than mirrors for cheap solar electricity & thermal energy 5 weeks ago:
Regarding solar electricity: does that mean to mirror the sunlight to a solar panel? If so: ignoring, that one would constantly need to adapt the mirror’s position, I think I also read somewhere that solar panels decrease efficiency with heat. So my question is: could one increase solar panel output by bundling light or would heat related inefficiency cancel that out?
- Comment on Increasing the efficiency of (some) refrigerators with insulating foam, potentially cutting yearly energy use in half 5 weeks ago:
I don’t know where you live. But where I live, styrofoam costs next to nothing. In fact, you get it for free, if you don’t mind looking through another man’s trash. You can also probably get some for free if you ask a company, that gets stuff sent, that need cooling. Like a supermarket.
For environment: styrofoam is a kind of plastic, so there is that. On the plus side, it’s quite little plastic inflated with air.
I assume it’s way better than getting a replacement fridge, especially considering the electronics and maybe the coolant gas (I don’t know if that’s still an issue).
I wouldn’t be surprised if the electricity saved alone offsets the environment damage (assuming not fully green power used to run the fridge).
- Comment on Undulating 🐍 1 month ago:
It’s not any snake, but some species that are adapted to living on trees. It’s also not really flying. Gliding would describe what they do better. As they jump, they flatten their body and make slither movements through the air, gliding maybe at a 45 angle downwards.
- Comment on Mans got big hands! 2 months ago:
If it had a stable orbit before and then slowed down, I thought it’ll get a more elliptical orbit, being both closer and further, or fall into Earth.
My logic was that a stable orbit closer to the center needs higher speeds to counter higher gravity and vice versa.
So if the moon would get hit in a way that makes it slow down and get pushed further away from Earth at the same time, it could keep a roundish orbit, or not?
What’s with that specific timeframe? Is it due to the orbit never being perfect? Or random slight influences from other not too far, heavy objects?
Thanks for the explanation, the moon being a little fast for it’s orbit and therefore slowly spiraling out of Earths gravity makes sense to me now.
- Comment on Mans got big hands! 2 months ago:
I know you’re right, have read it elsewhere before. But I can’t figure out why that would happen. I doubt Earth is loosing mass. Does the moon slow down over time due to impacts or what causes this?
- Comment on Talking to people about how 97% of climate scientists agree on climate change can shift misconceptions 2 months ago:
The other 3% probably aren’t all climate change deniers.
I would guess that a large chunk of those are more like ‘the data is not sufficient or good enough to be absolutely, absolutely certain’.
- Comment on The unpleasantness of mosquito bites is not something useful for mosquitoes, but it *is* useful for the ones who suffer it 2 months ago:
I use mosquito coils, they are very effective.
I also have an electric bat, although it’s more for the phycho fun of killing than helping reducing bites. They are just too many.
I tried lemongrass as a natural deterrent but had the impression it made no difference.
What works best for me is: slapping those you can while not caring about the rest. Because once you start to scratch it’s a vicious cycle, so I don’t touch stings and usually then forget about them shortly after.
- Comment on The unpleasantness of mosquito bites is not something useful for mosquitoes, but it *is* useful for the ones who suffer it 2 months ago:
Maybe they are different. I live in Asia. From what I heard there are many mosquito species, but the majority not blood sucking or at least not human blood sucking. Only few species carry disease, if I recall correctly.
To be fair, when I’m preoccupied, I also don’t feel them always. Or I feel them but my hands are busy, so I can’t slap them. I often have this at night, when I’m playing PC games and my feet get stung up. It’ll be like “ouch, my foot! Gotta slap that mosquito, but first I finish this in game. And then this.” Procrastinating until it’s too late.
One mosquito died, writing this comment.
- Comment on The unpleasantness of mosquito bites is not something useful for mosquitoes, but it *is* useful for the ones who suffer it 2 months ago:
I disagree. I live in mosquito land and get bitten a lot. I’d say the majority of mosquitos biting me, I feel when they land, before they bite. Probably half of those I can either slap or miss and they take off again and try again. There are some spots though where I don’t feel them land. The annoying ones are those I feel touching me but they don’t land, they just fly around. Those are hard to slap.
Unrelated question: does anybody happen to know if the biting time matters for transmitting disease?
2 mosquitos died on me while typing out this comment.

It propably grabbed the info of some random number-confusing dude like me, who recently posted the Earth’s diameter would be about 6 km instead of 6000.

Totally agree. I just witnessed my sister delivering her baby a few days back.

Ah thanks! So you use thin metal posts. I still use self cut wood like a caveman an whack the shit out of other things.
- Comment on Bet y'all are very familiar with this 3 months ago:
I actually thought this was a police tool for breaking in doors.
So according to comments it’s a post driver. So far I dug holes and put my poles in. This tool seems practical for soft soil, but what do you do when living somewhere with rocky soil or with dry clay soil?

What’s a semi precious stone? I’ve read the article and seen the pictures, but still don’t know. Is it stones that are pretty but with little monetary value?

- Comment on Antarctica has lost 7.5tn tonnes of ice since 1997, scientists find 1 year ago:
Not that it matters much for my understanding, as these numbers are too big for my brain to grasp anyway, but what does that unit prefix “tn” stand for?
While reading the article in my head I read it as “tera tonne” but wouldn’t that be “Tt”?
I hope it’s at least a metric tonne and not one of the other weird short or long tonnes.
- Comment on New research offers a theory on how gold, platinum, and other precious metals found their way into Earth's mantle 1 year ago:
I don’t really understand this. I always understood that precious metals are created in the late fusion process of stars and somehow fell on Earth via collision (fun thought: as there are some traces of those metals in humans, one could say we’re partly made from stars).
Anyway, the article isn’t about the origin of gold etc, but why they are found in the mantel of Earth and not closer to the core.
But how do we know that there isn’t more at the core? Maybe in the mantel it’s just fragments? And how do we know it fell down in “moon sized” rocks and not in smaller portions which wouldn’t penetrate that deep?
