The 4-D DOODLER

by GRAPH WALDEYER

"Do you believe, Professor Gault, that this four dimensional plane contains life—intelligent life?"

At the question, Gault laughed shortly. "You have been reading pseudo-science, Dr. Pillbot," he twitted. "I realize that as a psychiatrist, you are interested in minds, in living beings, rather than in dimensional planes. But I fear you will find no minds to study in the fourth dimension. There aren't any there!"

Professor Gault paused, peered from beneath bushy white brows out over the laboratory. To his near sighted eyes the blurred figure of Harper, his young assistant, seemed busily at work over his mathematical charts. Gault hoped sourly that the young man was actually working and not just drawing more of his absurd, senseless designs amidst the mathematical computations....

"Your proof," Dr. Pillbot broke into his thoughts insistently, "is purely negative, Professor! How can you know there are no beings in the fourth dimension, unless you actually enter this realm, to see for yourself?"

Professor Gault stared at the fat, puffy face of his visitor, and snorted loudly.

"I am afraid, Pillbot, you do not comprehend the impossibility of such a passage. We can not possibly break from the confines of our three dimensional world. Here, let me explain by a simple illustration."

Gault took up a book, held it so that a shadow fell onto the surface of the desk.

"That shadow," he said, "is two dimensional, has length and breadth, but no thickness. Now in order to enter the third dimension, our plane, the shadow would have to bulge out in some way, into the dimension of thickness an obvious impossibility. Similarly, we can not enter the fourth dimension. Do you see?"

"No!" retorted Pillbot with some
