The Shocking Truth Behind Arnold Nordsieck’s Differential Analyzer

The Shocking Truth Behind Arnold Nordsieck’s Differential Analyzer

David Brock Jan 18, 2018
In 1950, the physicist Arnold Nordsieck built himself this analog computer. Nordsieck, then at the University of Illinois, had earned his PhD at the University of California, Berkeley, under Robert Oppenheimer. To make his analog computer for calculating differential equations, the inventive and budget-conscious Nordsieck relied on US $700 worth of military surplus parts, particularly synchros — specialized motors that translate the position of the shaft into an electrical signal, and vice versa.

In the Holiday Spirit: Festive Music by Computer!

In the Holiday Spirit: Festive Music by Computer!

Chris Garcia Dec 21, 2017
Before computer gaming, music, and art became mainstay applications and tools for creation, engineers often created programs to demonstrate a machine’s capabilities in ways that were easy for the public follow. It took many years to get musicians into the idea of composing using a computer, and even longer to get general audiences to take those works seriously. Read More

Seymour Cray: The Man Who Brought Style to Supercomputers

Seymour Cray: The Man Who Brought Style to Supercomputers

David Brock Sep 14, 2017
A supercomputer is simply a computer that can perform many more calculations per second than the typical computer of its era. The definition is in constant flux. Yesterday’s supercomputer packed the punch of today’s smartphone. From 1969 to 1975, Control Data Corp.’s CDC 7600 was considered the world’s fastest computer, running at 36 megahertz. An iPhone 7, by contrast, runs at 2.33 gigahertz — nearly 100 times as fast as the 7600. Read More
An Early Door to Cyberspace: The Community Memory Terminal

An Early Door to Cyberspace: The Community Memory Terminal

David Brock Aug 16, 2017
COMMUNITY MEMORY is the name we give to this experimental information service. It is an attempt to harness the power of the computer in the service of the community. We hope to do this by providing a sort of super bulletin board where people can post notices of all sorts and can find the notices posted by others rapidly. Read More

Before ENIGMA: Breaking the Hebern Rotor Machine

Ralph Simpson Aug 08, 2017
The Hebern Rotor Machine was a major innovative leap in cipher technology and was also the first time electrical circuitry was used in a cipher device. Despite its failure to gain market acceptance, it had far-reaching historical significance in World War II and beyond. Unfortunately, its enigmatic inventor, Edward Hebern, would never be recognized or rewarded in his lifetime. Read More
