The Cosmos in Your Pocket: How Cosmological Science Became Earth Technology. I

Astronomy provides a laboratory for extreme physics, a window into environments at extremes of distance, temperature and density that often cant be reproduced in Earth laboratories, or at least not right away. A surprising amount of the science we understand today started out as solutions to problems in astronomy. Some of this science was key in the development of many technologies which we enjoy today. This paper describes some of these connections between astronomy and technology and their history.
