So what's the result in each of these graphs

plotting the angle

from an acute angle, well not even an acute angle but a minimal acute angle,

a straight line, up through a right angle at 90 degrees.

Back down into an obtuse angle that disappears at 180 degrees.

So each one of these graphs is a test of angle orientations

going from acute to 90 degrees, and

then back from 90 degrees through a series of obtuse angles to 180 degrees.

And the y-axis on each of these graphs is the probability, the frequency of

occurrence determined by the laser brain scanning and how often you see angles in

these different orientations in whatever way you present them in natural scenes.

Or carbonate scenes and as I said there's no real difference between those.

So what's the result or what's the result showing here?

Well, in each of these graphs, you can see that they're all basically the same.

There is a much higher probability of occurrence of lines that are either

acute or obtuse than right angles, so again, the frequency or the currents

now showing here in this different graphical way, is very different.

We don't have the same frequency of occurrence of any angle and

the general rule is that acute and obtuse angles,

the more acute they become, the more obtuse they become, the more frequent

they become in our experience, and the least frequent is a right angle.

Well, why should that be?

What sense does that make?

Why should it be that our presentation from the real world of right angles

is less frequent than our presentation of either acute or obtuse angles?

Well, the answer again, I think, is not hard to see.

And let me try to explain it to you in terms of this diagram,

which is the reason.

The reason for seeing relatively few or relatively fewer projections

from the real world that are right angles than projections that are acute angles.

So here is the right angle, and these lines are the same length.

Each of these four black lines is an identical black line.

So these black lines are arranged to make a right angle,

these black lines are arranged to make acute or obtuse angles.

Either one these angles are acute, these angles are obtuse.
