The Advanced Engine Test Facility was built in 1964, three years after President John F. Kennedy committed the United States to world leadership in aeronautical science. Conceived and designed by Wernher von Braun, the first director of the Marshall Space Flight Center, this facility was used to perform static tests on the booster of the Saturn V rocket, which launched Apollo 11 to the moon on July 16, 1969.
The stand has four concrete legs, each four feet thick and rising 144 feet to a steel superstructure supporting a 200-ton crane.

The 1992 Nobel Prize in physics was awarded to Georges Charpak, France, for his invention and development of detectors in high energy physics. Since 1959 Charpak had worked at CERN, the European laboratory for particle physics situated in the canton of Geneva in Switzerland. Charpak invented the multi - wire proportional chamber at CERN. The pioneering work was published in 1968. Largely due to his work particle physicists have been able to focus their interest on very rare particle interactions, which often reveal the secrets of the inner parts of matter.

In 1751 Benjamin Franklin published “Experiments and Observations on Electricity, Made at Philadelphia in America.”
Experiments summarized in this booklet determined the existence of positive and negative charges, and the difference between insulators and conductors. This work led to the invention of the lightning rod. Its complete construction was popularized in Poor Richard’s Almanack in 1753. This is the first practical engineering application of electricity.
A unifying theory covering static electricity, lightning, and stored charge was invented.
