During his seven-year study of making books with Riebau, he read many books. He read Isaac Watts's "The improvement of the mind". Faraday loved to use the ideas in this book in his work. He started to become interested in science, especially in electricity. He began to attend public lessons run by the best scientists in London at the time. He showed the notes he made to the great chemist Sir Humphrey Davy. Davy liked him and offered him a job as an assistant in March 1813.
