    • Methyl Methacrylate

      Methyl Methacrylate

      Methyl methacrylate has been used in plastic and resin manufacture for a number of years. It has been found to be significantly irritating to human eyes, skin, and mucous membranes. Exposure to methyl methacrylate has both short and long term effects and includes symptoms such as coughing, wheezing, chest tightness, and some neurological symptoms. The

    • How Nuclear Fusion Works

      How Nuclear Fusion Works

      Nuclear Fusion relates to nuclear power. So let us start with the process involved for getting nuclear power. There are, mainly, two processes involved: 1) Nuclear Fission Most of the present day nuclear power plants use this process to get power. This process uses a conventional method of splitting one atom into two. Here high-energy

    • How Do Ocean Currents Affect Climate?

      How Do Ocean Currents Affect Climate?

      Ocean currents are one of the main factors that affect climate. Other factors are proximity from the equator, distance from the sea, direction of prevailing winds and relief (mountains). But, for the most part, ocean currents act as one of the most important factors that influence the climate. And the reason why is because a

    • How Do Rockets Work?

      How Do Rockets Work?

      Since the United States first landed a man on the moon, children and adults have been fascinated with how rockets work! Whether one is trying to fly a small model rocket or launching a star ship to rendezvous with the International Space Station, the principles of how rockets work remain the same. Although rocketry has

    • Law of Universal Gravitation

      Law of Universal Gravitation

      The law of universal gravitation gives the attraction force between two objects due to gravity. Definition: For any pair of objects, they attract each other with a force that is directly proportional to the product of the masses of the objects and inversely proportional to the square of the distance between their centers of mass.

    • Body Armor

      Body Armor

      Body armor is a protective piece designed to stop projectiles. Modern body armors are also known as bulletproof vests. They are used by police, the Army and private security as default vest. The name bulletproof is deceptive though, as no body armor currently available can stop all bullets. The design and materials have evolved with

    • Vibration Dampeners

      Vibration Dampeners

      A vibration dampener is any material that is designed to absorb vibration. People come in contact with vibration dampeners on a daily basis. Some examples are carpeting, foam, rubber, and grass. Vibration dampeners are exceptionally useful in situations where heavy machinery is repeatedly colliding with itself or another surface, especially a floor. Vibration dampeners can

    • What is Luminol?

      What is Luminol?

      Luminol is a substance that has a blue or green glow when it comes in contact with blood, certain metals, or other oxidizing agents. It is made from hydrazine and hydrogen peroxide and exhibits chemiluminescence, the process by which light is emitted from a chemical reaction. Luminol has many uses, but is most widely used

    • The Peltier Effect

      The Peltier Effect

      The Peltier effect is one of the three separately identified effects to which “Thermoelectric Effect” or simply, “Thermoelectricity” refers. The other two are the Seebeck and Thomson effects. Discovery This effect is named after French physicist Jean-Charles Peltier, who discovered it in 1834. Peltier found that the junctions of dissimilar metals were heated or cooled

    • What Are Nanorobots?

      What Are Nanorobots?

      A nanobot is an extremely small robot that operates on a microscopic scale. Originally spoken of in science fiction circles, there has been an increased focus on it in biological and robotics research. The term nanorobot was created by combining the terms robot and nanometer. Other common names for robots of this size include nanobots,
