Operating since 1972, Eel River, New Brunswick is home to the world's first commercial solid state High Voltage Direct Current converter station. This 320 MW interconnection facility, built by Canadian General Electric and NB Power, incorporates high current silicon solid state thyristors to convert alternating current from Hydro Quebec to direct current and back to alternating, allowing asynchronous, stable power transfers to serve New Brunswick's Power's customers.

The HP-35 was the first handheld calculator to perform transcendental functions (such as trigonometric, logarithmic and exponential functions). Most contemporary calculators could only perform the four basic operations – addition, subtraction, multiplication, and division. The HP-35 and subsequent models have replaced the slide rule, used by generations of engineers and scientists.

The Voyager explorers, which provided scientists and the world with the first detailed pictures of faraway planets, were designed and tested during 1972 to 1977. The two most intelligent machines ever built in the NASA space program, the explorers were launched from Cape Canaveral, Fla., in 1977. Voyager 2 was launched first on August 20, followed by Voyager 1 on September 5.

The Apollo lunar module (LM-13) was developed by the Grumman Aircraft Engineering Corp. (now Northrop Grumman). The LM's main functions were to carry two astronauts from lunar orbit to the moon's surface, and then return them to lunar orbit to rendezvous and dock with the Apollo command-service modules. On the surface, the LM served as a shelter and base of operations as the astronauts carried out their exploration and experiments. On July 20, 1969, the LM "Eagle" touched down on the moon, becoming the first piloted spacecraft to land on a celestial body other than Earth.

The ABACUS II, designed and built by Texas Instruments, was the first practical automated production machine for the assembly of integrated circuits. Using heat and pressure, it bonded fine gold wire to microscopic contacts on the silicon chip and pin connections on the package.

The ABACUS II could maintain a positioning accuracy of ± 0.00025 inch while bonding up to 375 devices an hour. Following the success of this prototype, almost 1,000 ABACUS II wire bonders were built, making the economical mass production of integrated circuits a reality.
