Professor Wagner spoke quickly, without ceasing to write with the left hand. The right eye he continued to look at the visitor.

Gorev, at last, found gift for speaking.

– Tell how you can do it?. – And he looked at sloping eyes of professor and his left hand.

– To write with the left hand, to operate each eye separately, to work and to talk at the same time to you? The matter is that at me both brain hemispheres work absolutely independently and almost independently from each other.

But I have to explain you, so to speak, my starting point. As you know, officially I am professor of biology. Not less to you, I hope, also the fact that modern scientific disciplines extremely quickly break up to independent parts is known. Before our eyes the biological chemistry grows. Each new scientific branch, like the atomic theory, quickly grows in independent scientific discipline. Years are necessary to comprehend each of these certain scientific areas.

And meanwhile, to go forward, it is necessary to know also interdisciplinary sciences: the biology and physiology, chemistry and electricity, even geology and astronomy – all of them intertwine, mutually influence at each other. Some comprehensive mind is necessary to capture all this mass of knowledge. And life human is so short! To me for fifty. Ten more – another years, and the end. Before me enormous tasks which I want to resolve. Means, the first that I had to make for the purpose, it anyway to extend life. At first I thought of experiences of rejuvenation. What is already reached helped me: I look much younger. Perhaps, I will also return to these experiences. But so far I stopped that to me he was more familiar on the works on a brain.

The first that to me came to a thought, it to develop ability to work separately with each brain hemisphere. Unfortunately, I cannot stop in detail at these works: it would take too much time. I will tell only that here the major role is played by a training. You, maybe, had to see rhythmic gymnastics of Dalkroz? Kids quickly seize ability to operate the asymmetric movements: the right hand they can beat three time, left – two, besides at various rates, at the same time making various movements and legs. Something similar was made also by me, by the way, to full bewilderment of my housekeeper.

More difficult it appeared to seize the device of eyes. At us each eye has an independent control system, but owing to what we better see, fixing both eyes on one point, we developed a habit to coordinate the movements of eyes. Heredity of these skills complicated fight for «autonomy» in the movement of eyes. However such independence of the movement of each eye is quite possible. The chameleon can be an example of it. I was engaged in exercises. You see results. To learn to write and work the left hand did not represent work. It was necessary to pass to the last: to learn to perform at the same time two mental work, for example, to write with both hands two scientific research on different subjects at once. On it several years left at me. I achieved the. Thus I doubled the brain production.

But and it it seemed to me a little. Eight hours of a dream! We lose a third of human life on that helpless, half-dead state. Here what revolted me. To exempt mankind from a sleepy duty. What extraordinary prospects, what opportunities!. How many great works still great thinkers would give us if to present to them all nights for creativity! How many unfinished great works would be finished! As progress would move! The worker, having fulfilled the put hours at the machine, would spend night behind the book or public work. At us would not be illiterate. It is more than that, all would have an opportunity to become quite educated people. What with great strides progress would move! Here of what I thought…
