      What is a Karnaugh Map?

      A Karnaugh map is a graphical method or shortcut that can be used to solve Boolean algebra problems. Boolean algebra is used to conduct computations and create expressions from two values. This type of math creates the basis behind much of computer science and modern circuit card design today. Maurice Karnaugh created the current version

    • Potassium Dichromate

      Potassium Dichromate

      Potassium dichromate (K2Cr2O7) is an inorganic chemical reagent that is normally used as an oxidizer in industrial and laboratory applications. It is used to oxidize alcohols and convert primary alcohols to aldehydes and sometimes carboxylic acids. Unlike similar processes that use permanganate, only carboxylic acids result. The secondary alcohols are converted into ketones and no

    • What is Stomata?

      What is Stomata?

      Stomata are a special type of pore opening on leaves of plants. They are designed to absorb water from sources such as rain while also removing excess water in the plant through transpiration. The way that the stomata work is still a mystery as we truly do not understand what causes their functioning and how. The Role

    • Earth Cooling Tubes

      Earth Cooling Tubes

      Earth cooling tubes present an alternative for controlling temperature within residential and office buildings as well as greenhouses and other structures requiring temperature regulation. These tubes run underground and alter air’s cooling or heating temperature before it is allowed into a home or office. En route, the air releases its heat to the surrounding soil

    • Transmission Electron Microscope

      Transmission Electron Microscope

      The transmission electron microscope (TEM) is a scientific instrument that uses electrons instead of light to scrutinize objects at very fine resolutions. They were developed in the 1930s when scientists realized that electrons can be used instead of light to "magnify" objects or specimens under study. TEMs provided a means to go beyond the magnification

    • What Are Ceramic Briquettes?

      What Are Ceramic Briquettes?

      Ceramic briquettes are special accessories for gas grills that help consume less fuel. These briquettes come in various styles and can help to give the classic grilling to meats and other dishes that are prepared over the grill. The ceramic briquettes also help to distribute the heat more evenly and this is effective in producing heat for

    • Potassium Carbonate Dihydrate

      Potassium Carbonate Dihydrate

      Potassium carbonate dihydrate (K2CO3.2H2O) is a white chemical. Salt from potassium carbonate and water from the dihydrate are mixed into a deliquescent (wet salt). It is a strong alkaline solution that garners a variety of uses. The salt tastes like salt and alkaline material. Potassium carbonate dihydrate is generally used as a nutritional supplement in

    • The Coriolis Effect

      The Coriolis Effect

      The Coriolis effect is the tendency for a moving body that is on or above the Earth’s surface to drift sideways from its intended course due to the Earth’s rotation. The direction of drift is to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This is because the Earth’s

    • What is a Generator?

      What is a Generator?

      A generator (electrical) is a device that converts mechanical or chemical energy into electrical energy. Generators often use motors, turbines, engines, cranks, pistons, or other sources of mechanical energy. Likewise, generators may use chemicals or other materials that produce electricity when mixed or ignited. Generators do not produce electricity itself, but simply produce a flow

    • Magnetic Levitation Vehicles

      Magnetic Levitation Vehicles

      A magnetic levitating vehicle (MagLev) is a vehicle that uses a strong electromagnetic field to resist gravity and keep the vehicle floating out of the ground. The technical name is Electromagnetic suspension. The principle of the Electromagnetic suspension is to charge with the same pole the base of the vehicle and the rail with a
