Man nth

An assistant physicist receives a mysterious external intervention that grants him the power to alter matter, change size, and traverse space, and he experimentally demonstrates destruction, growth, and a visit to the moon. He confers with his chief about possible applications and hazards, while sensing an implanted urge to locate the source of the gift. The story follows his dawning realization of the ethical and practical consequences of limitless ability and his resolve to search the cosmos, exploring themes of scientific responsibility, curiosity, and cosmic purpose.
