Last Updated on December 22, 2022 by Sherouk Badr Shehata One of the most famous and revolutionary scientific theories of the 20th century is Einstein’s theory of relativity. It was proposed by the German-born physicist, Albert Einstein, in 1905 and has since then been accepted as a fundamental theory of physics. This theory has brought about a radical transformation in …

Last Updated on December 10, 2022 by Sherouk Badr Shehata Have you ever dreamed of defying gravity? That dream can now become a reality with the free-fall experiment. This experiment is a great way to learn about the principles of gravity, acceleration, and the conservation of energy. It is also a really fun and interactive way to explore one of …

Last Updated on November 16, 2022 by Sherouk Badr Shehata The PCR test is a method of amplifying specific DNA sequences using taq polymerase. This technique was first developed in the 1980s and has since revolutionized biology testing. Prior to PCR, only small amounts of DNA could be isolated and analyzed from samples. However, PCR allows for the amplification of …

Last Updated on November 15, 2022 by Sara Assem Have you ever wondered how physicists create free-body diagrams? What about economists or biologists? All of these professionals use specific symbols to chart the motion of an object. The importance and virality of free-body diagrams (FBD) in physics are beyond description. Free-body diagrams emerged since Newton’s laws of motion stretched out …

Last Updated on November 15, 2022 by Sara Assem A true wonder of humanity’s creative mind and engineering is the spring! With its many different forms and specific functions—the coil spring, the compression spring, the extension spring, the torsion spring, and more—our mankind was offered the chance to fabricate and invent many more useful objects. This man-made revolution of tools …
