Hertz, just with Augusto Righi, observed the electromagnetic waves practically.

They measured, okay, exist the electromagnetic waves, okay.

Marconi wasn't graduated, no?

He was something that he liked to do things practically.

He knew the Tesla, he went to him also to learn things about electromagnetics, okay?

They were friends.

Okay, he decided to do this experiment.

But the transmitter and the receiver, they were blocked in line of sight because of the earth curvature.

It is impossible.

It can't work, they used to say.

Why?

Because they are not in line of sight.

And because of the theory of Maxwell and because of the experiments of Augusto Righi and Hertz, it can't work.

It can't work.

But why?

He switched on the transmitter and the receiver and it worked.

Why?

Because there is in any black and white duality option, there is always a third via.

Good, yeah, so let's explore what that might be in this case.

In the case of Marconi, the existence of the ionosphere, because nobody knew of the presence of the ionosphere.
