      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

    • How a Laser Cutter Works

      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 Magnetic Wire?

      What is Magnetic Wire?

      Magnetic wire is a copper or aluminum wire that produces an electromagnetic field when wrapped into a coil and connected to a power supply. It is used in a number of applications and is a vital component in many different devices. Magnetic wire can be used in electrical to electrical, electrical to mechanical, and mechanical

    • How is Chemical Energy Used

      How is Chemical Energy Used

      There are many different kinds of energy but the single most widely used in society as well as in nature is chemical energy. Chemical energy allows energy to be stored for later use and it is also easy to access. Without chemical energy, many of the luxuries and even basic necessities that people have grown

    • What is Hindsight Bias?

      What is Hindsight Bias?

      Hindsight bias is when people exaggerate their confidence in an event that occurred based on predictions that were made prior to the event’s occurrence. Hindsight bias is just one type of bias that the brain uses to store and recall information. This is because people tend to focus on an event that occurred rather than

    • 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

    • Magnetic Propulsion

      Magnetic Propulsion

      Magnetic propulsion is the act of moving an object with magnetic fields and a flowing electrical current. The current is used to manipulate the system’s magnetic field or charge a fluid in the system that can be repelled. The Lorentz force then pushes the conductor in a direction that is perpendicular to the magnetic field

    • How Traffic Cameras Work

      How Traffic Cameras Work

      There are several different types of traffic cameras. Some types of traffic cameras are only focused on traffic patterns and traffic density. Other types of traffic cameras are placed in locations where traffic infractions commonly occur to capture traffic incidents and record the details for punitive purposes. Cameras for Traffic Monitoring Cameras for traffic monitoring

    • Vehicle Platooning

      Vehicle Platooning

      Vehicle platooning is one of the innovations in the automotive industry that aim to improve the safety, efficiency, mileage, and time of travel of vehicles while relieving traffic congestion, decreasing pollution and reducing stress for passengers. One of the recent demonstrations of this technology was during the PATH program done in California by 8 Buicks

    • What Causes Earthquakes?

      What Causes Earthquakes?

      An earthquake is caused when two blocks or plates of the Earth slip past each other in the lateral, vertical, or a combination of directions in a sudden manner. Due to the large pressures that develop between the Earth’s plates along fault lines at the Earth’s surface, one of the bodies will eventually give way.
