A superconductor is a metallic alloy that conducts electricity without resistance‚ below a certain temperature. Once in motion‚ an electrical current will flow in a closed loop within a superconducting material. This is the closest to scientists of a perpetual motion machine. In 1911‚ Heike Kamerlingh Onnes first observed superconductivity. He used mercury and cooled to four degrees Kelvin. When the mercury reached that temperature‚ the resistance disappeared. That meant that the electrical current

Flight is a phenomenon that has long been a part of the natural world. Birds fly not only by flapping their wings‚ but by gliding with their wings outstretched for long distances. Smoke‚ which is composed of tiny particles‚ can rise thousands of feet into the air. Both these types of flight are possible because of the principles of physical science. Likewise‚ man-made aircraft rely on these principles to overcome the force of gravity and achieve flight. Lighter-than-air craft‚ such as the hot

Miriam Yanez Physics 018-01 Literature Review 25 April 2012 Biophysics and protein dynamics have shaped our lives when it comes down to advancements in medicine. In living cells‚ proteins are the main components that keep the organism running at its best with every single protein and enzyme having their own function. The discovery of DNA‚ RNA‚ and other protein synthesis became the structures of life in a new perspective in the smallest ways leading to the continuing studies to uncover more

was made into 3D movie this year------the 100 anniversary of Titanic being sunk. The movie Titanic is close to the real accident happened on April 14th‚ 1912 and there’s a lot of physics involved in the movie. We have to admit that James Cameron really spent plenty of time on the causation of the accident. ① physics side note: Pressure (√) At the beginning of the movie‚ there is a group of people who want to find the invaluable “Heart of the Ocean”. They used submarine to get 3821 meters under

April 29‚ 2014 Abstract The objective project was to use our knowledge of physic properties to create a working car that was powered by a mouse trap. I found that the lighter the car was and the more traction the car had‚ the further it travelled. Introduction The purpose of this project was to create a car that is powered by a mouse trap. We were to use our knowledge of physics laws to make the best car we can. I knew from Newton’s Law‚ F=ma‚ that if my car had a lower
