How the EDSAC computer changed science in the 1940s and 50s

The Electronic Delay Storage Automatic Calculator (EDSAC), developed at the University of Cambridge, is one of the world’s earliest general-purpose computers. Volunteers at the National Museum of Computing in Bletchley Park, UK, have been constructing a working replica of an EDSAC machine. Once complete, it will be able to run EDSAC software that was published in scientific papers written in the 1940s and 50s. Such code might be among the world’s oldest.
