Tyson’s technique
Tyson invites his readers by stating that our perception of the world could be different if we had developed senses. Tyson also gives examples such as if we had developed vision, we could see the radio waves and x-rays with our own eyes. This technique helps in shaping the central author’s idea because it points the key concepts like we cannot rely only on our five senses; we have to use scientific items to understand what is beyond our senses.
