      Weather Modification Technology

      Weather modification refers to willful manipulation of the climate or local weather. Research done in this field goes back to as far as the early 1940s when the US military experimented with cloud seeding to stimulate rain. Today, private corporations have joined the weather modification research effort to protect people, cities and assets from the

    • 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 a Laser Cutter Works

      A Laser cutter is a machine that uses a laser to cut materials. The Laser Cutter works by making the laser enter through the side of the material that needs to be cut and shoots it through the axis of the beam. If a cut needs to be made and there are no edges near

    • What is a Rotameter?

      What is a Rotameter?

      A rotameter is a device that measures the flow rate of a liquid or gas in a tube. Karl Kueppers invented the rotameter in 1908, which has been widely used since then for a variety of applications. Rotameters are included in a class of devices known as “variable area meters” that depend on the substance

    • Methyl Iodide

      Methyl Iodide

      Methyl Iodide is a chemical compound that is relatively volatile. It is commonly found in the form of a dense, colorless liquid. It is also known as iodomethane and has the chemical formula CH3I (one carbon atom with three hydrogen atoms and a single iodine atom connected to it). Methyl iodide is a naturally occurring

    • What is the Speed of Light in MPH?

      What is the Speed of Light in MPH?

      The speed of light in MPH is 670,616,629 mph, 299,792,458 meters per second, or 186, 282 miles per second. Light takes approximately one second to travel the 238,854 miles to the moon. The speed of light is considered a physical constant that is used in many areas of physics. This is because light always travels

    • Fresnel Lens Projector

      Fresnel Lens Projector

      A projector is able to accomplish a projection with the help of a combination of lenses along with the other technical things. A Fresnel lens projector is one which has different Fresnel lenses placed in the projector. Fresnel Lens Fresnel lens was invented by a French physicist, Augustin-Jean Fresnel. These lenses have a large aperture

    • PIR Sensor

      PIR Sensor

      A PIR (Passive Infrared) sensor detects infrared light that is emitted from objects within its field of view. PIR sensors differ from other infrared sensors because they can only receive infrared waves. Because all objects emit infrared waves (electromagnetic waves that travel with heat), PIR sensors can detect objects that are in front of them.

    • What is Magnesium Used For?

      What is Magnesium Used For?

      Magnesium is a chemical substance denoted by the symbol Mg. It forms part of the Group 2 of the periodic table, thus making it an alkaline earth metal. Its atomic number is 12 and it is considered to be the 8th most copious element found in the earth’s crust. In terms of the human body,

    • Vibration Measurement

      Vibration Measurement

      Vibration measurements are made in order to identify when preventive or corrective repairs are required on machinery. These repairs are made in order to reduce or eliminate the noise that damaged equipment make. This prevents catastrophic failure of the equipment. Vibration measurements are frequently made on process control equipment and rotating machinery such as the
