Cooltimetravelbatbrat - Need Sleep

MERRY CHRISTMAS

Unusually excellent effort to cash in on superstition. Company and photographer unknown (circa 1940?).

So my friend and I found this at target

And it’s my new favorite thing

I don’t wanna post too much of the book bc y'know, copyright. But spoiler alert

He adopts 4 ducklings and cant get rid of them. Eventually he tries this

But the geese always come back to him even as adults

ITS BATMAN. SWEAR TO EVERYTHING THIS IS THE STORY OF BRUCE WAYNE REBLOG IF YOU AGREE!!!

March has some fucking nerve showing it’s face around here again

Reblog if you miss this good old days, when all our babies are babies, stand together, having fun, eat, sleep and training together, no hating, no fighting wait what…

Seriously, all the training course flashback this season are killing me….

A short note on how to interpret Fourier Series animations

When one searches for Fourier series animations online, these amazing gifs are what they stumble upon.

They are absolutely remarkable to look at. But what are the circles actually doing here?

Vector Addition

Your objective is to represent a square wave by combining many sine waves. As you know, the trajectory traced by a particle moving along a circle is a sinusoid:

This kind of looks like a square wave but we can do better by adding another harmonic.

We note that the position of the particle in the two harmonics can be represented as a vector that constantly changes with time like so:

And being vector quantities, instead of representing them separately, we can add them by the rules of vector addition and represent them a single entity i.e:

                                                  Source

The trajectory traced by the resultant of these vectors gives us our waveform. 

And as promised by the Fourier series, adding in more and more harmonics reduces the error in the waveform obtained.

        Have a good one!

WATCH TO DONATE: LEBANON (ALREADY MONETIZED WITH ADS)

The title is pretty self-explanatory, this is a video that you can watch to donate to the Lebanese Red Cross if you don’t have the means otherwise. I don’t think I’ve seen a link to this video outside Twitter, so I decided to make one.

The video has nice calming music with rain sounds in the background

Pls share if you can!

This is literally exactly how our campaign is going

Turns out the knife was cursed

“I pick up the knife” is now a mini-meme among my party and obviously it just means “I did something impulsive and now it’s going to take two sessions to solve.” 

Can someone explain to me why banking a breed of dog is the preferred solution.

The problem isn't with the breed its with the human owners, why can the law just make it harder for untrained or irresponsible people from having these dogs (I inclide my self in the untrained part before someone gets annoyed - I'm not the best animal person).

Feels like governments are looking for the easiest option for them selves.
