Hello everyone. I'd like your help.

There is a tale about Bucky Fuller that relates his use of a simple optical diagram at the beginning of lectures.

The diagram shows how the eye receives images from the outside world.

The story says that Bucky drew the attention of his audience to the fact that such images appear on the retina inverted and reversed, and that the brain corrects them.

It is taken to be a caution against naive realism, and by some in support of an 'observer-created universe'.

Can anyone tell me whether there is any truth to the claim that BF used such a diagram in any of his lectures?

With much thanks,
