This is the first commercial, human-blood heat exchanger. Developed in 1957, it permitted a patient's body temperature to be safely and rapidly lowered during open heart surgery to any desired and precisely controlled hypothermic level, then during the conclusion of the operation rapidly rewarmed to normal. Prior to this, hypothermic surgery required hours of preoperative, hard-to-control, external emersion cooling and postoperative rewarming.
Its design was a cooperative development between researchers at the Duke University Medical Center led by Dr. Ivan W.

Nicholas Montgomery Powers built the bridge. It was first constructed behind the village, then taken apart and reassembled over the stream. Some residents questioned the idea of re-constructing it, but Powers was so confident of the bridge's durability that he sat on the roof when the final trestles supporting it were removed. From his perch he reportedly said: "If the bridge goes down, I never want to see the sun rise again!"

This unit, retired from the Belle Isle Station of the Oklahoma Gas & Electric Company, was the first gas turbine to be used for electric utility power generation in the United States. It represents the transformation of the early aircraft gas turbine, in which the engines seldom ran more than ten hours at a stretch, into a long-life prime mover. This redesign was based upon creep-rupture tests of S-816 cobalt-base alloys for turbine buckets. The low-cost trouble-free service led to wide-scale adoption of the gas turbine, over 45 million kilowatt capacity (over 9 percent of U.S.

The longest steel-arch bridge in the world for 46 years, the Bayonne Bridge continues to be celebrated today as a major aesthetic and technical achievement. The 1,675-foot bridge replaced a ferry service which until then was the only means of crossing from the Bayonne peninsula to Staten Island. While providing this essential link in the transportation network of greater New York City, the bridge's mid-span clearance of 150 feet also allows for unobstructed navigation on Newark Bay, the main shipping channel to the inland ports of Newark and Elizabeth, New Jersey.

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.

Kinematics is the study of geometry of motion. Reuleaux designed the models in the Cornell collection as teaching aids for invention, showing the kinematic design of machines. The mechanisms in the collection represent the fundamental components of complex machines and were conceived as elements of a basic “language of invention.” Today the models are still used in the teaching of machine design and synthesis, robotics, dynamics, architectural drawing and mathematics.

The precision "choreographed" staging of Radio City Music Hall offers size and versatility, unlike any other. Built in 1932 by Peter Clark, its innovative elevator system is a forerunner of other stage designs (including the Metropolitan Opera House) as well as aircraft carrier systems built in World War II. These elevators can handle people, animals, props and scenery at variable speeds, delivering them to the stage or above and also dropping out of sight in front to reappear again in the back, just as effectively.

Around 1907, Belgian-born chemist Leo Hendrik Baekeland took two ordinary chemicals, phenol and formaldehyde, mixed them in a sealed autoclave, and subjected them to heat and pressure.
The sticky, amber-colored resin he produced in his Yonkers laboratory was the first plastic ever to be created entirely from chemicals, and the first material to be made entirely by man.
