Their fur is very dense, otter fur has more hairs per square inch than any other mammal, a million per square inch, like a hundred times what humans have. The oils excreted into their fur creates a hydrophobic layer that keeps the water on the outside. It's in nowhere near shark skin (which exhibits incredibe hydrodynamics, like we're studying it in labs to better improve aerodynamics of cars and planes, a single bite of food is enough to get a great white shark from California to Japan their skin is so efficient at moving through water), but it's very good at keeping the water out and their movement efficient, their hair does not cause Resistance like human hair does. Our hair hangs out and gets water in it and creates drag, otter hair seals itself around the meat and creates a cylinder, keeping happy warm dry otter inside.
I got the treat of touching/petting a wild otter while it was sedated, it's on of my top 10 experiences. It was not a happy camper when it woke up. It had to be in an ice bath while sedated otherwise it's hair/fur coat would've caused it to overheat while being knocked out because it is incapable of homeostatic regulation while sedated. When it woke up it was a wild otter in an ice bath, lil (haha, huge actually) dude was pissed.
I've never felt one under water, nor did I try to go skin deep when I had my opportunity, but I would guess they're pretty dry under there, I couldn't say for sure though.
I was quite impressed by the 20…17 eclipse over California, imo get lucky with a clear day, and stand near a tree without leaves, look at the kaleidoscope of shadows cast by the tree onto the ground, it’s indescribable when shadows don’t look like shadows any more.
Biology bs required 5 units of physics, physics was 3+1 for the lab. I haaaaate physics, love my chemistry, I’m pretty bad at higher math, physics just tries to be as tricky as possible while hiding behind the shroud of “this is how it works in life”. They made a "physics for biologists"class which was as much practical application of physics as they could put into a 1 unit 1 night per week course. I learned more, better, talking point physics in that class than any other.
Finals week was an optional “sasquatch” lecture that was open to anyone we wanted to bring, it was attended by more people than were actually in the class.
We learned how drag coefficients worked, how a great white child swim from California to Japan in 1 bite of food, how a blue whale and a bacteria both use the same amount of energy to move a distance. How terminal velocity means you can’t drop a mouse to it’s death. The optics of eyes… greatest physics course ever.
I was going to be disappointed that someone was just reading them, rather than directing people to the original source, but if it’s the source reading them, I’m rather happy, but the absorber doesn’t get the foot notes or image caption things.
Finished rewatching/first time all the way through watching psych.

I wanted to watch through Frasier before watching the new series, I think I’ve lost the desire to watch the new series, and I’m worried it’s damaging my ability to watch the original. It was so good, the doctor is out is one of my favorite episodes of television ever. But can I make it through 10 seasons to get there?
Homeowner with a decent amount of handiness but wondering if I’m going to bite off more than I can chew. Is it worth it to try and remove the old shower tub combo and replace it with a new one pretty much by myself? I realize this is a bit of a loaded question and can’t really be answered without knowing my skills but if...
Get a gym membership for shower usage just in case. There are many things that can balloon the project, father in law and I did his over a couple weeks, I wouldn’t put a "solid weekend"timeline on things. If it’s your only bathroom, be prepared for alternative showers, but it is definitely something a layman should be able to do.
Okay friends, any predictions for how the season finale will conclude? Since we haven’t seen Peri Gilpin yet, I assume our beloved Roz will make her appearance. I’m also curious whether more romance will bloom between Freddy and Eve.
I believe Heisenberg says there’s vagueness in the amount of things we can know at once. But I agree there’s nothing we shouldn’t be able to know, only things we know that we can’t know simultaneously, which imo is “vagueness”. However the understand principle is something I hope falls some day with better measurement devices than we had a hundred years ago.
Also everyone should listen to Sabine, she’s among the least biased science educators imo. People need to be really careful what they learn from YouTube creators, in fact that was a subject of a recent Sabine video!
I know their feeling. Enshitification for maximizing CEO/executives profits has been hammering so many businesses in California. We really need to kill this trend, and I think us Californians are the ones being screwed hard enough to be the first to take action.
Feels like a shower thought, but I seriously want to know if there are any implications, because it seems like identical twins are able to sense, understand, and almost be extensions of each other - finish each other’s sentences/thoughts. Some even claim to be able to sense their twin when they’re separate. Hard to believe,...

If you’re pulling it out and putting it back in any appreciable distance, it’s probably already plugged. Also if it comes out without unscrewing it might just be a marker. What does the in ground end of the pipe look like? Is it threaded? It could be someone is just having a laugh…
