Computer simulation was first started as a scientific tool in nuclear physics and meteorology in the period after World War II, but has grown rapidly become indispensable in a variety of disciplines, including astrophysics, high energy physics, climate science, engineering, ecology, and economics. Eric Winsberg trying to answer the questions in Science in the Age of Computer Simulation. Researching this problem with a philosophical lens, Winsberg explores the impact of simulation on issues such as the nature of scientific evidence, the role of values in science, nature and role in science fiction, and the relationship between simulation and experiment, theory and data, and theory -theory at different levels of description.
