You don't need to do that with [radio waves]. The beam divergence is sufficiently large that if you point the antenna at about the right place, and if you're within half a degree, you're usually in great shape.

This hydrogen gas emits radio waves with a wavelength of 21 centimeters, so they come in at about 1,420 megahertz on the radio dial. We were able to find that there is a magnetic field permeating this gas cloud and that its direction is pointing towards us above the cloud and then flips to pointing away from us on the bottom.

To be who we should be, realize first that we all have paths in life we can go down the good or better path or go down the dark path that will bring us misery the decision is ours and ours alone.But in the end, the no matter what lies ahead we will always have the choice to change our path if that is what we choose to do.Gary F Evans...

Cars they sound like waves that are breaking
On some distant shore
I gazed so hard into the great aching sky
It seemed that I， I wasn’t here no more
That my rushing blood was a river
My eyes two stars
My blowing hair all a quiver
A whispering field of grass
That murmurs as you pass
Oh my darlin’ Kathleen
That whispers out your name

The mobile phone is not a toy; it's a device that uses radio waves.

soulsThat we might break these molds
And free our restless souls
Start to believe
That we can rise above
Our pettiness and love
Like we ain't loved before
Free on this earth
As the surf that rolls
And crashes on the shore
And hey now don't run and hide
Your little heart away
If it's gone
We'll sure never find it
Pining for lost innocence
Tantalisingly I saw
Our shadows moving through the door
Traces from a different time
When I was yours and you were truly mine
All mine
