Alice’s Electrifying Guide to Big Sister Ariel’s AWESOME Paper on Electricity! ⚡🔋💡

By Alice Hi, friends! It’s me, Alice! 🐰💡 And guess what? My super-brilliant big sister Ariel wrote another AMAZING paper—this time, it’s all about ELECTRICITY! ⚡✨ At first, I was like, “Wait… isn’t electricity just the thing that makes my tablet work?” But then Ariel explained it to me, and WOW, it’s SO MUCH COOLER THAN THAT! 🤯💡 She told me that electricity is a form of energy that can create…

"haha, are you an art gay, a science gay, or a math gay"

Actually, I find the division between art, science, and math to be a very nebulous idea and useless when you actually interact with the universe. The more you learn about the world, the more you surround yourself with art and science and math, and you'll never be able to see it any other way and it will be beautiful. When I take your hand, it won't be the science of our atoms closing the distance between us that we will experience, but the math of our fingers interlocking and the art of our bodies that we will experience. You are math and you are science and you are art, and nothing will make you any lesser💛

Define a woman!

I’m gonna rant this here cus this argument keeps returning on the clock app and one day, I’m gonna be stupid and leave a comment in the wrong thread or smthn so I’m just gonna get it out of my system:

“How do you define a ‘woman’?”

Answer for idiots: you can’t.

You cannot possibly make a definition for the term ‘woman’ without excluding someone from the group when they clearly ARE part of the group (even if you’re a piece of shit transphobe and don’t want to include trans women). A woman is someone who has the potential to give birth? You just excluded every child before puberty, every infertile woman and every woman on menopause, next. A woman is someone who has a uterus? You just excluded a bunch of intersex women and all women who had a hysterectomy, next. A woman has a period? Excluded the millions of women who never get their period for various reasons AND all the women who take continuous birth control AND women who are pregnant AND again, little girls and women on menopause. A woman has to have XY chromosomes? Are you gonna check that for every feminine-looking person you’re gonna meet? How? Do you not think women with down syndrome are women?

Decades of feminism working so hard to make sure women are more than their genitals and potential to give birth, all flushed down the drain because you refuse to believe trans women are more than men in wigs? You’re weak as shit.

So answer for people who actually want to use their brain:

Woman is defined through experiences. Which experiences? Entirely up to whoever defines themselves as a woman.

The ‘female experience’ is so broad. You cannot possibly define it in one sentence and stick it on everyone who calls the word ‘woman’ their own.

You feel feminine and empowered by doing your nails? Congrats, that’s the female experience and makes you, therefore, a woman.

You feel feminine and empowered by wearing plaid and splitting wood in two with a giant axe? Congrats! Female Experience. Woman.

You feel feminine in a dress? Woman. You feel feminine in a tux and suit? Woman.

You feel empowered as a mother and love being pregnant? Woman! You despise the idea of being pregnant but find empowerment in your career? Woman! You feel like your period makes you more in tune with your femininity? Woman. You feel like your period makes you less than human and getting a hysterectomy makes you feel more comfortable in your body? Woman.

you love long hair? Woman. You love short hair? Woman.

You love loving men? Woman. You love loving women? Woman. You love both? Woman. You love everyone? Woman. You don’t feel like love is your thing? Woman!

Sitting at home with a good movie and a bottle of wine? That’s a woman. Getting bloody in a game of soccer? That’s very woman! Taking a walk with your dog? How very woman! Going to the gym? Such woman! Eating out with friends? Friend woman. Shooting a gun in the yard from the patio you built yourself? All woman!

Whatever the fuck makes you feel in sync with your femininity is your female experience, and if you have female experience and you like it, you are a W O M A N ✨

Same goes for men and the male experience btw! Since the question “what defines a man” is never ever ever ever ever ever ever ever EVER asked for SOME 👀 reason. (We all know the reason….) Also same goes for my fellow enbies and the non-binary experience. If painting your nails bring you closer to your enbie side, you’re non-binary.

Gender is such a deeply personal experience, it’s just dumb to define it for someone else, let alone the entire human species. It’s like asking to define a chair, like, you KNOW what it is but you can’t possibly define it without excluding some chairs (“has at least 4 legs”, that’s a horse also swivel chairs exist).

Sidenote: If some idiot tiktokker shoves a microphone and a camera in your face and goes “WHAT IS A WOMAN” or “HOW MANY GENDERS ARE THERE” just go along with whatever dumbass scenarios they come up with. “How many genders are there?” “My dude, as many as you want!” “Oh so like 40??” “Yep!” “Can I identify as a helicopter lol?” “Sure, who cares, do it!” “Should I demand everyone at my job calls me a helicopter” “You can go to your local townhouse, request to change your name to ‘helicopter’ and they’ll most likely let you. You’re an adult, you can do whatever you want as long as it’s not hurting others.” “You don’t think it would be dumb of me to do that?” “Why would I care, I don’t know you?”

I've said this before but Why do people position "themes and analysis" and "shipping" as mutually exclusive opposites. maybe I find two characters thematically interesting and want them to analytically fuck about it.

"Scientists in Singapore have broken a long-standing limitation on the ability to generate electricity from flowing water, suggesting that another elemental force of nature could be leveraged for renewable electricity: rain.

With the simplest and smallest scale test setup, the team could power around 12 LED lightbulbs with simulated rain droplets flowing through a tube, but at scale, their method could generate meaningful amounts that could rival rooftop solar arrays.

Singapore experiences significant rainfall throughout the year, averaging 101 inches (2581 millimeters) of precipitation annually. The idea of generating electricity from such falling water is attractive, but the method has long been constrained by a principle called the Debye Length.

Nevertheless, the concept is possible because of a simple physical principle that charged entities on the surface of materials get nudged when they rub together—as true for water droplets as it is for a balloon rubbed against the hair on one’s head.

While this is true, the power values thus generated have been negligible, and electricity from flowing water has been limited to the driving of turbines in hydropower plants.

However, in a study published in the journal ACS Central Science, a team of physicists has found a way to break through the constraints of water’s Debye Length, and generate power from simulated rain.

“Water that falls through a vertical tube generates a substantial amount of electricity by using a specific pattern of water flow: plug flow,” says Siowling Soh, author of the study. “This plug flow pattern could allow rain energy to be harvested for generating clean and renewable electricity.”

The authors write in their study that in existing tests of the power production from water flows, pumps are always used to drive liquid through the small channels. But the pumps require so much energy to run that outputs are limited to miniscule amounts.

Instead, their setup to harness this plug flow pattern was scandalously simple. No moving parts or mechanisms of any kind were required. A simple plastic tube just 2 millimeters in diameter; a large plastic bottle; a small metallic needle. Water coming out of the bottle ran along the needle and bumped into the top section of the tube that had been cut in half, interrupting the water flow and allowing pockets of air to slide down the tube along with the water.

The air was the key to breaking through the limits set by the Debye Length, and key to the feasibility of electricity generation from water. Wires placed at the top of the tube and in the cup harvested the electricity.

The total generation rate of greater than 10% resulted in about 100 watts per square meter of tube. For context, a 100-watt solar panel can power an appliance as large as a blender or ceiling fan, charge a laptop, provide for several light bulbs, or even a Wi-Fi router.

Because the droplet speeds tested were much slower than rain, the researchers suggest that the real thing would provide even more than their tests, which were of course on a microscale."

14 year old's who encountered near death ( or just death) experiences, with their parents failed radioactive experiments, and turned them almost into the experimental thing. Had a hectic time in the beginning learning about their new found abilities. Turned into vigilantism to protect their neighborhood. Plus really into science stuff. Cant forget the having a main bully, 2 besties, and a mad scientist in their main villain roster

And both had experiences with the infinity gauntlet - and being displaced into the dc universe specifically into Gotham, moslty joining the batfam, in fanfiction. ( which is totality has no ref to it here def not 0(-( this is just a simple graveyard meet up)

honestly pretty common requirements for all todays vigilantes

^^^^ Yes, this. I came to the same conclusion.

The idea that it's "psychological conditioning" based on media (whether it's Mr. Rogers or Godzilla or anything else) mandates that everyone's been exposed to some form of that media and that just isn't realistic. There simply isn't enough of that kind of media going around, and it's not enough to claim that everyone has and doesn't remember.

It's more likely just a consequence of the way we naturally view the world. Definitely as kids playing with miniature models/toys on the floor, but also just in everyday life: things sitting on a table or your desk or the counter provide a distinctly different experience than things far away down the street. That's what your brain associates that field of view with.

Take your standard "close-up" field of view and mash it onto scenes you're most used to being large-scale and far away, and you get the odd sensation that you're looking at a model.

It doesn't work for every scene. Even some of the extra examples in the comments are poor candidates and fall flat in providing that feeling. Some just look like you've selectively blurred the perimeter just for effect and they don't look tiny.

The short answer is... a tilt-shift lens.

The slightly more complicated answer is... Mister Rogers.

Depth of field is the area in front and behind your chosen focus point that remains in focus and then slowly gets blurry as you get farther away.

Shallow depth of field only has a narrow slice of the image in focus and gets blurry super quick. This is caused by a large lens aperture and being close to the subject.

Deep depth of field can extend through the entire picture if your aperture is small and you are super far away.

Usually the depth of field lines up with the image sensor of your camera. So if it is tilted forward, the plane of focus matches.

The stuff outside the green area would be blurry. The edges of the green would be slightly blurry. And the dashed green line would be the sharpest area of the photo.

But the tilt-shift lens allows you to create chaos with your plane of focus. In most cases, you would use this to flatten the depth of field so you can get a 2D plane entirely in focus.

If you were to use a normal lens, the bottom left and top right would be blurry.

But with a tilt-shift lens you can do this.

The green area is taking a little nap on the floor.

However, there is an unintended side effect created by this lens. (The "Scheimpflug intersection" if you want to go down the rabbit hole.) You can choose absolutely wacky planes of focus that create a very narrow depth of field over a geographically large area.

Believe it or not, this is when psychology comes into play.

And possibly Mister Rogers.

Our only reference for such a large area having a shallow depth of field is our memories of miniatures on TV. So Mister Rogers and Thomas the Tank Engine trained our brains to see this effect as... small.

Depth of field shrinks the closer you are to something. And when filming miniatures, you are placing the lens close to the scene. But the scene represents something big in our minds. We buy the effect, but not 100%. That blurriness wouldn't be there at a regular scale. So our subconscious remembers we are watching small things pretending to be big. It just files that away in the back of our mind.

And then when we see something like this...

Our brain is all, "Look at all that tiny shit!"

Without Mister Rogers, our brains may have never made these connections and tilt-shift photography may just make us wonder why everything is all blurry. That connection to past experience is vital for this effect to be convincing.

Brains are neat.
