Technological advancements have led to significant changes in society. The earliest known technology is the stone tool, used during prehistory, followed by the control of fire—which in turn contributed to the growth of the human brain and the development of language during the Ice Age, according to the cooking hypothesis. The invention of the wheel in the Bronze Age allowed greater travel and the creation of more complex machines. More recent technological inventions, including the printing press, telephone, and the Internet, have lowered barriers to communication and ushered in the knowledge economy.
The Fabyan Windmill is an authentic, working Dutch windmill dating from the 1850s located in Kane County, Illinois, just north of Batavia, Illinois, off Illinois Route 25. The five-story wooden smock mill with a stage, which stands 68 feet (21 m) tall, sits upon the onetime estate of Colonel George Fabyan, but is now part of the Kane County Forest Preserve District. In 1979, the windmill was listed on the National Register of Historic Places. The following year, the windmill was selected to be on a U.S. postage stamp, as part of a series of five windmills in a stamp booklet called "Windmills USA." It originally operated as a custom grinding mill.
Gerard K. O'Neill (1927–1992) was an Americanphysicist and space activist. As a faculty member of Princeton University, he invented a device called the particle storage ring for high energy physics experiments. Later, he invented a magnetic launcher called the mass driver. In the 1970's he developed a plan to build human settlements in outer space, including a space habitat design known as the O'Neill cylinder. He founded the Space Studies Institute, an organization devoted to funding research into space manufacturing and colonization. In 1965 at Stanford University, he performed the first colliding beam physics experiment. While teaching physics at Princeton, O'Neill became interested in the possibility that humans could live in outer space. He researched and proposed a futuristic idea for human settlement in space, the O'Neill cylinder in "The Colonization of Space", his first paper on the subject. He held a conference on space manufacturing at Princeton in 1975. Many who became post-Apollo-era space activists attended. O'Neill built his first mass driver prototype with professor Henry Kolm in 1976. He considered mass drivers critical for extracting the mineral resources of the Moon and asteroids.
