In the late summer of 1983, when video games were relatively new, astronomer, cosmologist, and science communicator Carl Sagan recognized their potential value as he imagined “how to design a home video game which would teach a great deal of astronomy in a context as exciting as most violent video games.” His typed notes reflected his interest in creating a game that would include a hundred thousand stars in its model galaxy and take place over stellar evolutionary events.

Atmospheric scientists study the chemical composition of the atmosphere. More specifically, they look at how atmospheric gases, liquids, and solids interact both with each other and with the earth's surface. This helps people understand such phenomena as air pollution, ozone depletion, and climate change. Shawn Urbanski is a research physical scientist at the U.S. Forest Service’s Rocky Mountain Research Station in Missoula, Montana. He studies wildfire smoke chemistry and the impact of wildfire smoke on air quality.

Computer simulations have become essential to scientific investigation and engineering design, thanks to advances in mathematical modeling, game theory, and computing technology. Simulations now provide an indispensable tool for investigating the properties of natural and built systems in science, engineering, economics, and social science.
