What did you know about this experiment ...?

From the 'focus' nature of the parabola learned in this experiment

There was nothing to hijacked

But, "information presentation" on how to do it

And did not you understand us through our considerations?

I could prove in science that it sounds like magic "To make a sneaky story with a normal voice"

There are few things I've found, but there are so many such things in the world

It was not possible to make an experiment of "parabola" with many mathematical aspects to be a "physical" site?

I think so
