    • How Do Nuclear Power Plants Work?

      How Do Nuclear Power Plants Work?

      A nuclear power plant works in the same way that a coal power plant works. Heat is generated which causes water to turn into steam. This steam turns a turbine which causes a generator to spin which generates electricity. However, a nuclear power plant does not use coal. Instead, the fuel of choice is uranium

    • What Are the Steps of the Rock Cycle?

      What Are the Steps of the Rock Cycle?

      The rock cycle is an essential geological model that depicts the unique changes that rock undergoes during a set time period. The three major rock types are sedimentary, metamorphic and igneous. Rocks are formed and obliterated in cycles. The rock cycle depicts the formation, destruction and restoration of rocks. These changes take place due to

    • How Does Solar Energy Work?

      How Does Solar Energy Work?

      Solar energy is created by taking sunlight (solar thermal energy) and converting it into electricity. This conversion takes place via a medium that absorbs the solar energy and then converts it into usable electricity that can power various objects that are electrically operated. While the solar panel is not the most effective method of generating

    • What is Rhodium Plating?

      What is Rhodium Plating?

      Rhodium plating is a type of metal plating that prevents an object from being scratched or tarnished and improves the object’s color quality. Rhodium is a precious metal that is five to twenty-five times as expensive as gold and is used for plating jewelry and other objects in order to make them brighter, smoother, and

    • How Overhead Projectors Work

      How Overhead Projectors Work

      Overhead projectors work with the help of transparencies. All data are printed on top of the transparencies. Before starting up, be sure to have a socket with live electricity where you can switch the overhead projector. The power buttons are usually made of first class plastic, the “click” sound is heard; it means it has

    • Who Discovered Quantum and Particle Physics?

      Who Discovered Quantum and Particle Physics?

      During the nineteenth century the main theory in physics was still Newtonian Mechanics. With the advances in electricity, magnetism and the studies about light, it was clear that the theory had its limitations. The limitations appeared in the limits of the too small (atomic size) or the too fast (light speed). The study of the

    • How Laser Skin Treatment Works

      How Laser Skin Treatment Works

      A laser skin treatment is a relatively new technology that surgeons have only recently begun using. It is when the surgeons utilize lasers (containing carbon dioxide) to vaporize the skin’s upper layers, consequently allowing a new layer of skin to form. The technique is commonly used to fine tune wrinkles and various face lines, especially

    • What is Interferometry?

      What is Interferometry?

      Interferometry is a series of techniques that uses a series of superimposed electromagnetic waves to extract data and other insights regarding the waves. The device used to measure the waves is an interferometer. Interferometry is primarily used in the fields of fiber optics, engineering metrology, optical metrology, seismology, oceanography, astronomy, particle and nuclear physics, quantum

    • Paraffinum Liquidum

      Paraffinum Liquidum

      Paraffinum Liquidum (mineral oil) is a petroleum by-product and is created through distillation. Mineral oil is completely transparent and is basically a liquid form of petroleum jelly. It is produced in large quantities and is used in many different ways all over the world, mostly due to its low toxicity and low cost. Mineral oil

    • What is Electroluminescence?

      What is Electroluminescence?

      Electroluminescence is the phenomenon where a material emits light when electricity is passed through it. It is one of the greatest discoveries of the twentieth century and other forms of luminescence, including incandescence, chemiluminescence, cathodoluminescence, triboluminescence, and photoluminescence rival it. Electroluminescence generally involves a material producing light without producing heat. It is different from black
