      What is Stereoscopic Vision?

      The term stereoscopic vision refers to the human ability to view with both eyes in similar, but slightly different ways. This allows humans to judge distance, which develops their ability to have true depth perception. Historically, the human’s ability to view the world through stereoscopic sight has given him/her a significant advantage over entities and

    • Hydronic Air Handlers

      Hydronic Air Handlers

      Hydronic air handlers have become a popular installation for home owners who build a new home or are replacing the HVAC system in an existing one. A hydronic air handler is significantly more fuel efficient, runs quieter, and produces more comfortable heating than a traditional furnace. It does this by providing uniformly heated air, thereby

    • 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

    • Hoverboards


      Hoverboards in movies are fictional, but there are actual hoverboards — though they are not the size of a skateboard. Hoverboards are simple contraptions that allow the user to travel without parts that would roll over the ground. Hoverboards are an offshoot of the hovercraft. The hovercraft (also known as air-cushion vehicle or ACV) is

    • What Are Ionic Compounds?

      What Are Ionic Compounds?

      An ionic compound is any compound in which an electrostatic force holds the ions together. Ionic compounds are made of positively charged particles that rest against negatively charged particles in order to balance out the two particles’ magnetic imbalance. They can be found in both solid and liquid states, although solid ionic compounds are poor

    • Combustible Gas Detectors

      Combustible Gas Detectors

      A combustible gas detector is a device that allows the user to detect and analyze any nearby concentrations of combustible gases. Combustible gases are simply gases that will catch on fire when mixed with oxygen and ignited. There are many different types of combustible gases and each one requires its own method of analysis. Some

    • How Magnets Work

      How Magnets Work

      A magnet is an object formed out of any type of material that can produce its own magnetic field. Such materials include hard magnets and soft magnets. Examples of hard magnets are neodymium magnets and refrigerator magnets which always remember the way in which they were magnetized.Examples of soft magnets are electromagnets, which can be

    • Facial Recognition System

      Facial Recognition System

      Facial recognition systems are computer programs that are used for automatically identifying a person. Research on this technology started in the mid 1960s. This technology works by using several facial features in a person's image and comparing these with existing images in the database. Facial recognitions systems are used as an additional and mass security

    • 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

    • Automatic Number Plate Recognition

      Automatic Number Plate Recognition

      Automatic number plate recognition is a system designed to automatically recognize and store license plate number data on vehicles passing through a certain point. This is one of the mass surveillance systems that utilize optical character recognition programs and hardware capable of reading 1 plate/second off vehicles running at a maximum of 160 km/hr. Some
