Эллипс. Эллипс? Что такое эллипс?

Переделка песни "living next door to Alice"

Once at school, when i was at the board
Teacher said,  "I suppose you heard, about ellipse"
And she rushed to the blackboard and took a piece of chalk
When she wrote an equation, our class was shocked
The teacher said "this is a canonical form of an ellipse"

(ELLIPSE? WHAT, the fuck, is ellipse?!)

It is a conic section, a bounded one, of course,
To be more strict, however, it is the set of points
Such as the sum of distances to two fixed points - focae - is constat
Within two drawing pins and with the help of thread
You can draw ellipse easily, the anyone you need.
And that's what you should know for understanding what is ellipse.

Тen years later, when I was an engineeer
I needed ellipsograph for one of my blueprints
   oooooo   ..... but it broke down
Then I took two drawing pins and i took a thread
And drew a perfect ellipse exactly wich i needed
My collegues said I'm genious, (I agreed) and told them 'bout ellipse.

(ellipse? what the fuck is ellipse?)

It is a conic section, a bounded one, of course,
To be more strict, however, it is the set of points
Such as the sum of distances to two fixed points - focae - is constat
Within two drawing pins and with the help of thread
You can draw ellipse easily, the anyone you need.
And that's what you should know for understanding what is ellipse.

Times have passed, once my little son
Came and asked me about the Sun and (the) planets
I took a book for children in order to explain
And found there thing astonishing my brain:
I suddenly discovered that an orbit has a shape of ellipse

(ellipse? what the fuck is ellipse?)

It is a conic section, a bounded one, of course,
To be more strict, however, it is the set of points
Such as the sum of distances to two fixed points - focae - is constat
Within two drawing pins and with the help of thread
You can draw ellipse easily, the anyone you need....
And that's what you should know for understanding what is ellipse.

But I ll never get used going round the Sun on ellipse...
No, I ll never get used going round the Sun on ellipse...
