The Noria al-Muhammadiyya is the most famous of many norias in Hama. This giant operating noria is unique in both size and age. Built in 763 AH, or 1361 CE, and still in use today, it is a stand-alone water pump. The river that provides the water it raises also serves as its sole source of energy.

The Southwest Research Institute Split-Hopkinson Pressure Bar apparatus is a mechanical test instrument used to characterize the dynamic response of materials at high strain rates (typical of impacts and explosions).
The apparatus, based on devices invented by Bertram Hopkinson and Herbert Kolsky, was developed at SwRI in 1962 by Dr. Ulric Lindholm. Initially created to evaluate the behavior of metals under various conditions, the SwRI Split-Hopkinson Pressure Bar has since been applied to a wide range of materials.

The Wildcat's innovative "Sto-Wing" mechanism developed on the XF4F-4 prototype by Leroy (Roy) Grumman (1895-1982), a founder of Grumman Aircraft Engineering Corporation, was crucial to the U. S. Navy's success during World War II.
The idea of a folding wing was not new: as early as 1920, F.M. Osborne patented a high-wing monoplane with folding wings, but never produced this design. A 1928 plane with folding wings designed by W. Leonard Bonney crashed on its first flight.

Bread is considered a basic foodstuff; eaten down through the ages, it continues to be a staple of the modern diet. The development of baking powder made baking easier, quicker and more reliable for bakers in the mid-19th century. Eben Horsford’s unique formula was an important innovation and made the making of biscuits, cookies and other quick baking products simpler than before.
