WHAT CONTRIBUTION DID LUIS ALVAREZ MAKE TO MODERN SCIENCE?
This American physicist developed the linear accelerator in 1946 for which he won the Nobel Prize in 1968. He and his son, Walter, first proposed that massive extinctions around the Jurassic — including that of dinosaurs, were caused by the impact of a large space object. WHAT IS SPELEOLOGY? It is the science that explores and studies caves found under the earth’s surface. WHAT IS WAVE-PARTICLE DUALITY? In classical physics, all the physical phenomena concerning light, viz. reflection from a glazed surface, refraction through a prism, interference when two or more sources of light were put together and diffraction, the bending of light along edge of an object, could be explained with the wave theory. But this description does not hold for the microscopic world. In modern physics, light is made of discrete packets of energy. WHAT IS THE FARADAY CAGE? The Faraday Cage, also known as Faraday Shield or Screen, is a network of parallel wires connected to a common conductor at one end to pro
