A Crucial Moment in Technological History

10-23-17

 

Take a deep dive into a crucial moment in technological history with Carver Mead, Gordon and Betty Moore Professor of Engineering and Applied Science, Emeritus. In this first of a series of videos being produced by the Caltech Archives, titled 'My First Chip’, Professor Mead tells the story of meeting Gordon Moore, who would soon predict that every year the semiconductor industry would double the number of transistors that could be fabricated on a commercial integrated circuit. Carver Mead and his students worked on the physics of ultra-small transistors, and showed that, in addition to allowing greater density, they ran faster and used less power. This work proved that Moore’s prediction did not violate any laws of physics, and it became known as 'Moore's Law'–the term coined and made famous by Professor Mead.

Electrical Engineering Alumnus Harold Rosen Passes Away

01-31-17

Harold Rosen (PhD '51, Electrical Engineering), the father of geostationary satellite communications, passed away on January 30, 2017. His Caltech education, he told a Caltech publication in 2012, "gave me such a good grounding in the fundamentals" that he felt capable of attacking any technical problem in almost any field.

Celebrating 50 Years of the Argon Ion Laser

02-14-14

William Bridges, Carl F Braun Professor of Engineering, Emeritus, discovered and patented the Argon ion laser on February 14, 1964, while at Hughes Research Laboratories. Today noble gas (argon, krypton, xenon) lasers are used in a variety of applications including DNA sequencers, cell sorters, eye surgery, and laser light shows. Professor Bridges' research work with lasers involved an airborne night reconnaissance system (AN/AVD-3), space communications systems, early high power laser weapons (the carbon dioxide gas dynamic laser), and hydrogen maser clocks for the global positioning system. He also holds the patent for the Ionized Noble Gas Laser. [Oral History of Prof. Bridges]

50th Anniversary of the Launch of the First Geostationary Satellite

07-26-13

On July 26, 1963 Caltech Distinguished Alumnus Harold A. Rosen (MS 1948 EE, PhD 1951 EE) and his team at the defense electronics laboratories of Hughes Aircraft Company in Culver City overcame technical and political hurdles to successfully launch the first geostationary satellite, Syncom. Dr. Harold A. Rosen has earned worldwide recognition for his pioneering work in the field of communications satellites and is known as “the father of the geostationary satellite” in that he formed and led the team that designed and built Syncom, and subsequently, as Vice President, went on to help build the world’s largest communications satellite business at Hughes Aircraft Company.

Professor Martel Passes Away

04-04-12

Hardy C. Martel, Professor of Electrical Engineering, emeritus, passed away on March 29 at his home in Altadena. He was 85. "He was one of the first at Caltech to do research on information science and communications technology," says Roy Gould, the Simon Ramo Professor of Engineering, Emeritus, a lifelong friend and colleague of Martel. "His strength was in his basic, intuitive grasp of ideas and how things worked." [Caltech Feature] [E&S Article in pdf]
