To do mathematics, you have to work with some bizarre concepts, such as something having position but no size.

They know I’m here, yet everyone ignores me. I persist
In fighting for a bit of recognition,
But still I get the feeling people think I don’t exist.
Perhaps it’s just a quirk of definition:

They say, you see, my area is vanishingly small;
Co-ordinates are all they say I’ve got.
So people talk about me like I wasn’t here at all:
“There isn’t any point,” I hear a lot.

Such folk are just plain ignorant – well, that’s my gut reaction;
I’d like to put their noses out of joint.
I’m really an important mathematical abstraction:
The point is – are you listening? – I’m a point!
