6. The printing press: The printing press, invented in the 1440s, allowed for the mass production of books and other printed materials, leading to the spread of knowledge and ideas.
7. The steam engine: The steam engine, developed in the 18th century, revolutionized transportation and industry.
8. The computer: The development of the computer in the 20th century has had a profound impact on almost every aspect of society.
