There is only One True Parabola

Behold the one true parabola! All parabolas are exactly the same, just zoomed in and out.

MATT PARKER: Stand-up Mathematician

It took some time but the acid finally kicked in around the end of the video.

Thought I was going to learn math about parabolas, ended up joining a cult conspiracy against "Big Math"

[iangolsby]

When I was in algebra II freshman year I was sitting bored in class and started getting the weird idea that all parabolas were the same just zoomed. Then I fell asleep and forgot about it. 3 years later I've found this video and wow thank you

Okay.. the ending justifies the Rest of the video...

[PlutoTheSecond]

So much for the separation of church and scale.

Came for the Parabola, stayed for the spiritual experience

4:17 Proof that Matt lives in a Non-Euclidean plane of existence!

"Triangles come in all shapes and sizes." Um...pretty sure triangles come in just one shape. Triangle.

Hello! Do you have time to hear about our lord and savior, the one and only true parabola?

-> "Are you religious?"
-> "I'd like to introduce you to my religion"
<- "what's your religion"
-> "9:18"
<- "I'm interested"

*All conic sections with the same eccentricity are similar.*
All circles are similar(e=0)
All parabolas are similar(e=1)
All lines are similar.(e→∞)
You can make an extension of this video where you discuss this in greater detail.

You drew a real Parker Square of a circle there Matt.

Before you finished the explanation, I tried to visualize it in my head and it’s fairly simple to understand intuitively. A “fatter” or wider parabola is simply a zoomed in “skinny” parabola. As you zoom into a point of the parabola, it flattens out, thus, getting wider.

I’m not 100% certain this assumption is correct, but it feels pretty solid.

I literally asked my math teacher this same thing 2 years ago. her answer was :" no it doesn't work that way "...
be careful whom you trust!

THERE IS ONLY ONE TRUE PARABOLA

STANDUPMATHS IS THE MESSENGER OF PARABOLA

PARABOLA IS THE GREATEST

1:38 oh, now he’s just showing off, how rich he is

[Niko_demus]

I figured this out in school and my math teacher was not happy about it since I started drawing only standard parabola with the ruler and then adjusting the coordinates accordingly. After the second homework we were given the system we have to draw it into (also on all the exams). Mathematical creativity is not always appreciated in school.
