"Tell the chef, the beer is on me."

Devil’s Tramping Grounda wooded section of Chatham County, North Carolina. A forty foot in diameter circle can be found there. Any objects that appear in the circle will mysteriously disappear or get moved from within the circle. No wildlife, vegetation, or inanimate objects can be found in the circle known as the Devil’s Tramping Ground. This phenomenon was first discovered in the early 1800s and is believed that Satan paces around this circle and ponders about ways to undo mankind..boy scout troups have tried camping on it, and woken up in their tents a few miles away. Some guys tried to stay up all night in a tent on the spot, and later reported that a soft, soothing melodic voice lulled them to sleep and they too woke up a few miles away

#why is that so cute tho#like most of the time u hear about this shit and its like ‘they got their eyes clawed out or disappeared or died’#but this is like#’casually picks up your stuff and moves it somewhere else or gently sings you to sleep’#like dang thats the most polite demonic circle ive ever heard of what a sweetheart

A Minimalist, Maximally Imaginative Geometric Allegory for the Essence of Friendship and Creativity - Wednesday by Anne Bertier

What a circle and a square can teach us about empathy, collaboration, and the origin of great ideas.

One of the cutest abstract minimalist storybook I've ever seen & I wanna get a copy of it bc sheer cuteness

Radians: the natural way of measuring anglesThis is the third animation I posted today: here’s the first and the second. Be sure to check the other two if you missed them!

Another one for Wikipedia. Tumblr forced me to cut the amount of frames in half. Here it is in its full, smooth glory.

There’s a multitude of ways you can specify an angle, from the familiar degrees to the obscure—and altogether alternative—provided by "spreads".

However, only one of these angle units earns a special place in mathematics: the

.radianThis animation illustrates what the radian is:

it’s the angle associated with a section of a circle that has the same length as the circle’s own radius.For a unit circle, with radius 1, the radian angle is the same value as the length of the arc around the circle that is associated with the angle.

In the animation, the radius line segment

r(in red) is used to generate a circle. The same radius is then “bent”—without changing its length—around the circle it just generated. The angle (in yellow) that’s associated with this bent arc of lengthris exactly 1 radian.Making 3 copies of this arc gets you 3 radians, just a bit under half of a circle. This is because half of a circle is π radians. So that missing piece accounts for π - 3 ≈ 0.14159265… radians.

Our π radians arc is then copied once again, revealing the full circle, with 2π radians all around.

There are several great reasonsto use radians instead of degrees in mathematics and physics. Everything seems to suggest this is the most natural system of measuring angles.Radians look complicated to most people due to their reliance on the irrational number π to express relations to circle, and the fact the full circle contains 2π radians, which may seem arbitrary.

In order to simplify things, some people have been proposing a new constant τ (tau), with τ = 2π. When using τ with radians, fractions of τ correspond to the same fractions of a circle: a fourth of a tau is a fourth of a circle, and so on.

Tau does seem to make more sense than pi when dealing with radians, but pi shows up elsewhere too, with plenty of merits of its own.

I, for one, do enjoy the idea of tau being used,

exclusively, as an angle constant, so that it immediately implies the use of radians. If such were the case, a student seeing Euler’s identity for the first time, but in terms of tau, would be immediately compelled to think in terms of rotations:e^{τi}= 1 would instantly convey the idea of a full rotation, bringing you back where you started. That seems like a good thing.

EDIT: here’s a long post where I detail my thoughts on the pi vs. tau discussion.So

happy Pi day!(or half-tau day, if you prefer!)

Exactly.

Imagine a wall full of circular holes, that circles can keep walking in and out of with no difficulty.

Now imagine that the triangles manage to get the resources together, after years of not being able to fit through the circle’s holes, to drill a single triangle space into the wall.

Now imagine that the circle — who previously supported the triangle’s efforts because they are well-rounded (har) and value equality — comes along and sees the construction project. But instead of being happy, they get angry.

“Well, I won’t be able to fit through your hole!!!!” the circle cries.

“I helped you get the drill!!!!” the circle shrieks.

“Make it fit me too!!!!” the circle demands.

The triangles, barely holding it together enough to get a triangle hole together, stare at the circle in confusion.

“You have all the holes you need,” the triangles explain. “This is for us. You don’t need to fit through our hole, too.”

“YOU’RE BEING UNEQUAL AND HURTING MY FEELINGS!” the circle wails. “I DON’T SUPPORT YOUR HOLE IF IT DOESN’T FIT ME TOO. GIVE ME MY DRILL BACK.”

“It’s not your drill, it’s our drill. You helped us get it, because you said you cared.”

“I ONLY CARED WHEN I THOUGHT YOU’D MAKE A HOLE EVERYONE COULD FIT THROUGH. YOU’RE PERPETUATING INEQUALITY!!!”

“Why is it up to us, the small group that has never been able to fit through the wall at all, to make a hole everyone can use? Why isn’t it up to you, the people who have been able to cross back and forth at will for years? We just want to see the other side; why are you yelling at us?”

“I DIDN’T ASK TO BE BORN A CIRCLE, OMG. I’VE HAD TO WORK HARD ALL MY LIFE TOO. YOU’RE JUST BEING BIGOTED AGAINST ME BECAUSE OF SOMETHING I CAN’T CONTROL, JUST LIKE EVERYONE IS AGAINST YOU.”

“You are interfering with our project and asking us to comfort

youwhile we’re trying to make progress. Please leave.”“I’m going to tell everyone about this,” the circle warns. “Nobody will support you now.”

“Apparently nobody ever did,” the triangles sigh, getting back to work.

It’s kind of sad

That we have to draw comics using colorful shapes

To explain systematic inequality to peopleI have to reblog this again for the amazing story.

Reblogging again for the story.
