Idk what Heated Rivalry is about, but its crazy that Tumblr can just allow gifs of these white boys having sex on trending

Meanwhile every post that has a "mature label" behind it is a photo of like a fully clothed Black woman

Physics is to math as Python is to Haskell.

In physics, everything is typed dynamically. Sure, the codomain, i.e. the units of a function or quantity is usually static, but the domain, i.e. the dependent variable are whatever they need to be.

Meanwhile in math, we specify what our objects are. They are statically typed. Even if I have no clue what a Haskell function does, I can at least look at its type signature to get a rough idea.

I wish physics were statically typed with explicit type annotations because it is driving me up a wall that, for instance, both the force between two points and the net force of a single point are referred as 'the force'. They have different type signatures!

That, and energy. 'Energy' is not conserved. The total energy of an isolated system is, but the energy at a point given by the potential energy field can of course change. This ambiguous use of language makes it really difficult for idiots like me to learn physics. I am not good with wishy-washyness. If you input ambiguous language into my brain, I can regurgitate grammatical connections between vocabulary words (you know, the stuff even an LLM can do), but you can't expect genuine insight from me. For that, I need clear, bright lines. How can you have theorems if you don't spell out your assumptions!

#IThere are some pretty good books that attack it from a mathematics perspective

#Applied Exterior Calculus, Quantum Theory for Mathematicians, Lie Algebras in Particle Physics, and Introduction to Mechanics and Symmetry are fantastic sources for topics for more advanced physics!

#Quantum chromodynamics is broken though...

I wish I could be more loving and kind but my love language is physical touch and my hands are sticky.

you dont have to be a parent to understand the horror of walking into a room to discover that the baby crawled out of his crib and onto that pottery wheel you forgot to turn off, and while the baby is spinning around and around, the dog is sitting there all calm, like a person, gently using his paws to fashion the babys soft cartilage head into something a little more modern.  it might be the classic tale of bad parenting, but lets see where the dog is going with this

This post is from 2013. It has less than 100 notes. Together we can revive this work of art that tragically ahead of its time. We’re ready for it now

[kwarrtz]

It's insane that the single most complete and lucid collection of graduate-level physics texts available is entirely free and self-published by one dude from Cambridge. Like, look at this fucking page! I guarantee you every one of those lecture notes is among the best ever written on its subject. In a few cases, they're practically the only ever written, like the one on the quantum Hall effect I'm working through right now.

This man puts Landau and Lifschitz to shame.

*looks at sherlock* it’s very smoll

[frougpepe]

oh my god it was me

[thealogie]

this is the very first ever documented use of smoll. you’re all a witness to language history here.

You don't look how I expected at all, I always envisioned a 50- something old timey train conductor

I was actually 16 in that photo.

Does this make a little bit more sense?

Or maybe this one?

real I fear

finally watched barbie last night. i think it was refreshing to see gerwig's exploration of population exchange in europe during the chalcolithic age. barbies are clearly coded to be early european farmers, living in a comfortable yet stagnant environment of europe at the tail end of the ice age, with a culture revolving around female fertility (notice the second character introduced is a pregnant barbie). the second sequence shows up ken(gosling)'s enterance into the story on beach, mirroring the arrival of western steppe herder cultures as glaciers in europe retreated.

once barbie and ken venture into the "real world" (prohpetic vision of the bronze age), ken adopts advanced technologies like the horse (horse), patriatrchy (worship of a male solar deity), and cars (the wheel, expoundable into the horse-driven chariot). his donning of the fringe jacket and cowboy hat stir within the audience a yearning for westward expansion, from the pontine steppe through the pannonian basin and beyond.

ken transforming barbieland into the kendom mirrors the replacement of early european farmer (vinča, varna cultures etc.) with corded ware and bell beaker cultures, settled iterations of the kens' previously pastoral culture. the only barbie not assimilated into the new cultral zeitgeist is weird barbie (basques), herself a cultural isolate even compared to other barbies pre-invasion.

the final battle scene between the two ken factions places particular focus on archery, hallmark of the mongol civilization, which was the last of the steppe invasions of europe. notice in this situation, gerwig's bravery in correctly having ken (asian) represent the kingdom of hungary (asian), whereas ken (gosling) is of course the ever-lasting scythian spirit emanating from the steppe. some scholars have suggested the light-blue void where the last battle takes place to be a metaphor tengri.

some other stuff happened as well but i didn't really get how that fit into the greater story i guess. what was the deal with the old jewish lady LOL !

[gingerhaze]

Some character designs with some…atypical color choices? I guess. I don’t know what’s going on in that area.

This is Nimona and her supervillain friend (He doesn’t have a name yet, I’m working on that). Nimona is his sidekick/squire, they’re like the Batman and Robin of slightly Medieval villains, but she’s actually way more evil than him. He does what he does to make a point, and he doesn’t really want anyone get hurt - Nimona just gets a kick out of destroying stuff.

I’m going to attempt to make a two page comic with them? We’ll see how this goes.

Hello crocheting mutuals, in like a month I have to lead an introductory crochet class, so if anyone has any tips about teaching crochet to other people that would be very appreciated!

[dingdongs-bingbong]

Hey spinning mutuals! I am trying to find cool pretty support spindles that are a bit less that 50 dollars. So if you have any etsy shops/makers in mind, please comment them of this post if you feel like it.

[dingdongs-bingbong]

This remains to be my most ambitious crochet project I have ever done. It took me three months to make and I honestly don't think I could do it again as I forgot to write down the pattern. While not essential, the simple collard turned out to be a really nice touch.

[littlebirdinagarden]

I am having an absolute rollercoaster of the sickness, where I thought I was getting better and have only gotten worse again. Please can you send me joyful things. Send me floof you’re excited to spin, or pretty yarn you just bought, or the little creature that lives in your home, or the sheep you saw out in a field recently, or a beautiful photograph you have taken. Please I need cheering up because I don’t have any energy to do any of my usual favourite things

If you are feeling sad with the ugliness of the world, just remember that the fundamental group of an H-space is always abelian. A fascinating interaction of algebra and topology.

[saja-star]

I've had a hard time articulating to people just how fundamental spinning used to be in people's lives, and how eerie it is that it's vanished so entirely. It occurred to me today that it's a bit like if in the future all food was made by machine, and people forgot what farming and cooking were. Not just that they forgot how to do it; they had never heard of it.

When they use phrases like "spinning yarns" for telling stories or "heckling a performer" without understanding where they come from, I imagine a scene in the future where someone uses the phrase "stir the pot" to mean "cause a disagreement" and I say, did you know a pot used to be a container for heating food, and stirring was a way of combining different components of food together? "Wow, you're full of weird facts! How do you even know that?"

When I say I spin and people say "What, like you do exercise bikes? Is that a kind of dancing? What's drafting? What's a hackle?" it's like if I started talking about my cooking hobby and my friend asked "What's salt? Also, what's cooking?" Well, you see, there are a lot of stages to food preparation, starting with planting crops, and cooking is one of the later stages. Salt is a chemical used in cooking which mostly alters the flavor of the food but can also be used for other things, like drawing out moisture...

"Wow, that sounds so complicated. You must have done a lot of research. You're so good at cooking!" I'm really not. In the past, children started learning about cooking as early as age five ("Isn't that child labor?"), and many people cooked every day their whole lives ("Man, people worked so hard back then."). And that's just an average person, not to mention people called "chefs" who did it professionally. I go to the historic preservation center to use their stove once or twice a week, and I started learning a couple years ago. So what I know is less sophisticated than what some children could do back in the day.

"Can you make me a snickers bar?" No, that would be pretty hard. I just make sandwiches mostly. Sometimes I do scrambled eggs. "Oh, I would've thought a snickers bar would be way more basic than eggs. They seem so simple!"

Haven't you ever wondered where food comes from? I ask them. When you were a kid, did you ever pick apart the different colored bits in your food and wonder what it was made of? "No, I never really thought about it." Did you know rice balls are called that because they're made from part of a plant called rice? "Oh haha, that's so weird. I thought 'rice' was just an adjective for anything that was soft and white."

People always ask me why I took up spinning. Isn't it weird that there are things we take so much for granted that we don't even notice when they're gone? Isn't it strange that something which has been part of humanity all across the planet since the Neanderthals is being forgotten in our generation? Isn't it funny that when knowledge dies, it leaves behind a ghost, just like a person? Don't you want to commune with it?
