Red Hot

Today LEDs come in yellow, orange, green, turquoise, blue-violet, and even white. But first there was red—and first there was Nick Holonyak

They shine from clocks and traffic lights; they blink on our car dashboards. They flash on the soles of children’s running shoes; they glow from the coffeemakers in our kitchens. They tell us that our modems are connecting to our networks; they reassure us that our cellphones are on. They lit up the face of the first personal computer and the first wristwatch with an electronic display; they illuminate today’s suspension bridges and video billboards.

These tiny semiconductor sandwiches known as light-emitting diodes (LEDs) can now create every color of the rainbow and more. But LEDs all trace their genealogies back to the first visible laser diode—and it was red. The father of that primordial visible diode is Nick Holonyak Jr., the winner of this year’s IEEE Medal of Honor.

Frederick P. Brooks Jr., a prolific computer scientist and longtime professor of computer science, died on 17 November at the age of 91.

While working as a project manager at IBM in the 1960s, the IEEE Life Fellow led the development of the System/360 computer family. It was the first vertically compatible family of mainframe computers. Brooks also developed IBM’s OS/360, the world’s largest software project at the time. He is credited with coining the term computer architecture, which is used to describe how hardware and software are organized to make up a computer system and the operations which guide its function. He wrote The Mythical Man-Month, a book of essays published in 1975 that detailed lessons he learned from challenges he faced while developing the OS/360.

Adhesive staking of DIP component on a circuit board using Master Bond EP17HTDA-1.

The main use for adhesive staking is to provide extra mechanical support for electronic components and other parts that may be damaged due to vibration, shock, or handling.
