Hypnoteacher will be used to remember a big amount of information in a short time

Teacher Tenin’s head ached unbearably. He felt awful. In the past four hours he had read and mastered four books on atmosphere regeneration, and had
memorized the Venus plan. He had been forced to resort to the hypnoteacher for this, and after the hypnoteacher it was absolutely essential to lie down and
sleep it off. But he couldn’t. Perhaps he should not have overloaded his brain
that way, but the teacher did not want to take chances. He had to know ten
times more about Venus and about the project than the four of them put
together. Otherwise his plan wasn’t worth wasting time on.
