Can Someone Explain To Me Why Banking A Breed Of Dog Is The Preferred Solution.

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!

Be careful with your honey, my friends! <3

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

Holy shit Jiang Chang’s parents never fucking stop with the emotional abuse

Boy ain’t my favorite character, but I’m forming a protection squad anyways, because someone needs to defend his skill and tell him he has value as a person and as a cultivator

Reblog if you wanna join the Jiang Cheng Protection Squad

Dear Reddit and Twitter refugees:

You've probably already been told to change your icon, post and reblog stuff you like, Tumblr has holidays, etc.

But in case you weren't aware before....

When AO3 (Archive of Our Own) goes down for any reason, Tumblr flips the fuck out and panics. AO3 starts trending almost immediately.

Do NOT try to calm your neighbors down! Panicking with them until AO3 goes back up is the correct course of action.

Thank you and have a day.

So let me get this straight, Damian grew up in the League of Assassins before he met his father Bruce for the first time, Jason spent a couple of years training with them before he met his ex-father Bruce for the first time after his resurrection and Cassandra has worked under the league before she met her future father Bruce for the first time.

Three of Bruce children/would-be-children worked in the same exact organization possibly at the same exact time before they even knew they were meant to be siblings, and no one bothered to write something about that?? I’m disappointed in this fandom right now.

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!
