He pays attention to observing natural phenomena and studying scientific problems. Starting from practice, he engaged in scientific experiments and observations, answered the question of "what is electricity" in electricity, called electricity in different states "positive electricity" and "negative electricity", put forward the "first theory" in electricity, and revealed the essence of lightning phenomenon in atmospheric electricity, which was called "the second Prometheus".
These epoch-making achievements in electrical research made him a world-famous first-class scientist. He also studied optics, heat, acoustics, mathematics, oceanography, botany and so on. And there are a series of inventions, such as new stoves, lightning rods, electric wheels, three-wheeled clocks, bifocal glasses, automatic barbecue ovens, glass musical instruments, overhead book readers, new street lamps and so on.
Therefore, with only two years of primary school education, he was awarded a master's degree or a doctor's degree by six or seven universities in the United States, such as Harvard University, Yale University, Oxford University, Edinburgh University and St. Andrews University.
