Chaos and the Double Pendulum
A chaotic system is one in which infinitesimal differences in the starting conditions lead to drastically different results as the system evolves.
Summarized by mathematician Edward Lorenz, ”Chaos [is] when the present determines the future, but the approximate present does not approximately determine the future.”
There’s an important distinction to make between a chaotic system and a random system. Given the starting conditions, a chaotic system is entirely deterministic. A random system, on the other hand, is entirely non-deterministic, even when the starting conditions are known. That is, with enough information, the evolution of a chaotic system is entirely predictable, but in a random system there’s no amount of information that would be enough to predict the system’s evolution.
The simulations above show two slightly different initial conditions for a double pendulum — an example of a chaotic system. In the left animation both pendulums begin horizontally, and in the right animation the red pendulum begins horizontally and the blue is rotated by 0.1 radians (≈ 5.73°) above the positive x-axis. In both simulations, all of the pendulums begin from rest.

idk man it just makes me so so so sad when you’re watching a cutiepie talk about their passion like when they light up and start bubbling over with words and then all of a sudden they stop themselves and say stuff like “sorry, i know this is boring” or “sorry i just got excited”

like you know somewhere in their life someone they respected told them “shut up nobody cares” and ever since they can’t talk about their favorite things without apologizing every 5 seconds

you know what’s funny is that i’ve always been more obsessed with female celebrities for some reason and i used to think that was bc i saw them as role models and wanted to emulate them or whatever

but it turns out i’m just really hella gay

anxiety.

Or, you know, you could just stop saying sorry.

I take it you don’t have anxiety.

You can’t “just stop saying sorry”. You do something, something so little, like accidentally bump into someone. You feel horrible about it. Your brain starts panicking and you have trouble trying to breathe. You stutter an apology. They say it’s okay, but you accidentally do it again, and you apologize again. They just say “Aha, you can stop saying sorry.” And you feel horrible that you’ve probably made them angry or upset, so you mutter out an apology for the third stupid time, and they just say to stop saying sorry. Stop saying sorry. 

You can’t just tell someone to stop saying you’re sorry.

I want that comment on flyers so I can hang them in my school

reblogging this one for the GOOD commentary.

If you’re going to tell someone to stop saying sorry say, “You don’t have to apologize to me.” and smile. If they say sorry again just say, “You’re fine.” and keep smiling and move on. The faster the situation is resolved the faster the person with anxiety can start to calm down. Please don’t get angry at someone for saying sorry, sometimes that’s all the person feels like they can do.

I’ve always been really bad about this and as a kid I’d always do it around my parents and my mom would always say “STOP SAYING YOURE SORRY.” thank you to the helpful comment.

People who say sadness doesn’t hurt physically apparently never experienced feeling so sad. I’ve felt it in my legs, my jaw, my head, my quivering lips, aching eyes, and my aching chest. It hurts my chest the most because it literally feels like your heart is in pain.

A neutral density filter is a filter that reduces or modifies the intensity of all wavelengths or colors of light equally, giving no changes in hue of color rendition. The filter reduces the amount of light entering the lens, allowing the photographer to select combinations of aperture, exposure time and sensor sensitivity to avoid overexposed pictures. It would normally be attached to the lens, but is hand-held here to illustrate the effect.
