“Scientists Come In Two Varieties, Hedgehogs And Foxes. I Borrow This Terminology From Isaiah Berlin

“Scientists come in two varieties, hedgehogs and foxes. I borrow this terminology from Isaiah Berlin (1953), who borrowed it from the ancient Greek poet Archilochus. Archilochus told us that foxes know many tricks, hedgehogs only one. Foxes are broad, hedgehogs are deep. Foxes are interested in everything and move easily from one problem to another. Hedgehogs are only interested in a few problems that they consider fundamental, and stick with the same problems for years or decades. Most of the great discoveries are made by hedgehogs, most of the little discoveries by foxes. Science needs both hedgehogs and foxes for its healthy growth, hedgehogs to dig deep into the nature of things, foxes to explore the complicated details of our marvelous universe. Albert Einstein and Edwin Hubble were hedgehogs. Charley Townes, who invented the laser, and Enrico Fermi, who built the first nuclear reactor in Chicago, were foxes. It often happens that foxes are as creative as hedgehogs. The laser was a big discovery made by a fox. The general public is misled by the media into believing that great scientists are all hedgehogs. Some periods in the history of science are good times for hedgehogs, other periods are good times for foxes. The beginning of the twentieth century was good for hedgehogs. The hedgehogs—Einstein and his followers in Europe, Hubble and his followers in America—dug deep and found new foundations for physics and astronomy. When Fermi and Townes came onto the scene in the middle of the century, the foundations were firm and the universe was wide open for foxes to explore. Most of the progress in physics and astronomy since the 1920s was made by foxes.”

for people who are unaware of why the riots in minneapolis started happening, here’s the facts:

it wasn’t george floyd’s protesters who started reacting violently; it was the cops.

the protest was peaceful until the cops showed up in riot gear, and started using water cannons, followed up by tear gas and rubber bullets. i got videos from friends who were there, of people screaming and running away from the cops shooting the water cannons, rubber bullets and throwing tear gas at them. they were even shooting at the protesters dragging people away to get medical attention.

speaking of medical attention, dispatch refused to provide any medical attention to the protesters. people literally had to drive their bleeding friends to the hospital because they refused to send ambulances.

cops are using non-lethal weapons in a lethal way. they shot rubber bullets into people’s heads and injured them. there’s dozens of photos of protesters with bleeding head wounds from the rubber bullets.

multiple people used police scanners and heard that there were undercover cops pretending to be violent protesters who were throwing rocks and whatnot at the police, with dozens of eyewitness accounts confirming that information.

the person who instigated all the chaos last night (it was a fire at an autozone) with the looting and burning buildings is highly suspected to be an undercover cop pretending to be a protester, because the video of him keeps getting taken down. protesters tried to stop him but couldn’t because he had a hammer and they were scared for their safety.

the cops jammed cell phone towers and cut live streams to interrupt broadcasts and to prevent people from seeing what was really going on and who actually started the violence.

the cops lied about protesters being armed and about throwing rocks and are literally trying to continue the violence happening and yet no one is holding them accountable for that.

and during all this, the cop that murdered george floyd still hasn’t been arrested. he has had more than ten complaints filed against him and was involved in three other civilian shootings in the past. and yet he’s still out free along with his three other buddies involved, probably sitting on his couch while all this chaos is happening.

so don’t get it twisted. the cops just want to change the narrative to make it look like they’re the wounded and righteous party, when they’re the ones who started reacting violently in the first place and are still acting violently. so don’t you ever forget who started this tragedy and murdered someone, and who are continuing to react to the situation with violence.

From the fundraising webpage:

This fundraiser is to help our dear friend Mohammed Abu Matar to rebuild Tashkeel3D; a key manufacturer of 3D-printed medical equipment in Gaza that was destroyed by Israeli Occupation Forces during this week’s attack on Gaza. Tashkeel3D is where Gaza’s first 3D printer was built, where medical devices have been manufactured for years and led the opensource culture was in Gaza. Tashkeel3D is the original Gaza affiliate of the Canada-based Glia Project, an organization founded by ER doctor Tarek Loubani which works with regional partners to develop and produce low-cost and open-source 3D-printed medical equipment. Among other tools, Tashkeel3D has developed 3D-printed tourniquets: compression devices used to limit bleeding. They were threatened with bombing previously by the Israeli Occupation Forces. While no specific reason was given, they were producing tourniquets to support Gaza’s medical system at the time, which was likely what brought them to attention.

The destruction severely hampers efforts to produce 3D printed tourniquets. Tashkeel3D’s offices effectively represent half of Gaza’s 3D printing capacity. All proceeds will go to Mohammed to help him rebuild Tashkeel3D. We ask that you please donate any amount that you possibly can and that you share this link with your network.

Harry isn’t quite out of his teens when it fully hits him—the war, the blood and the guts spread across the corridors of Hogwarts, the screams and sobs, the nightmares, the shadows that never seem to leave him.

It’s too much.

He gets a flat in London—Muggle London. Hermione and the Weasleys give him space. Kingsley ensures the wizarding world gives him privacy. Not that some aren’t reluctant. Rita Skeeter releases articles every day, wondering when their Boy Who Lived will return.

But Harry doesn’t see those articles.

He tries to forget who he is for awhile.

His flat is cozy. He stuffs it with plants and paintings and books. He has a cat (or three). He wears sweaters and blazers with corduroy pants. He goes to the market every morning to buy fruits and vegetables. That’s where he meets the kindly old woman who lives down the street.

She lived through World War II and so many other wars, wars that Harry has never experienced but can only imagine.

She goes to his house and she goes to hers. There’s always tea and small cakes and dinners and cocoa—apparently she believes that a teenager needs cocoa—and baking and reading and knitting.

Harry uses magic to brew the cocoa one day, not realizing that she’s standing in the doorway. She calms him by telling him that she knows all about magic. 

Their conversations shift after that. They talk about their favorite creatures and how hard it was to watch them perish before their eyes. They talk about the wall that seemingly gave way to let them enter the magical world. They talk about lions and friends and family and love and betrayals and life and death.

“When did you leave?” Harry asks one day.

She pauses, a hand resting on his cat’s head. After a moment, she looks up with a heaviness in her eyes, a heaviness that Harry sees when he looks in the mirror everyday. 

“I was young,” she says. “Younger than you are now. But I had already grown up. I didn’t want to leave, not really, but it became too much.”

“Do you regret it?”

“Some days I do, some days I don’t.” 

“Yeah…”

It’s a few months later, when he’s helping her shovel the first snow from her walkway, that he asks, “Did you ever try going back?”

“Even if I wanted to, I couldn’t,” she says, shoving a cup of cocoa into his hands. “I was shut out as soon as I hesitated.”

He pauses, nearly dropping the cocoa, before whispering, “That’s horrible.”

“What about you?” She escorts him inside, her cane tapping against the floor that he’s magically heated to warm her feet. “Would you be welcomed back?”

“Oh, yeah,” Harry says. “Til they turn on me because they don’t like the color of my shirt or because I sneezed the wrong way or because—you name it.”

She laughs and he smiles.

“Imagine that,” she softly says. “Rulers of our worlds and we’re not even allowed in them.”

“Imagine that.”

He does go back to the wizarding world, of course, but he never forgets his London flat. He visits the street from time to time, knowing that Susan Pevensie will be there, ready to push a cup of cocoa into his hands.
