      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

    • Potassium Chlorate

      Potassium Chlorate

      Potassium chlorate is a chemical compound that contains chlorine, oxygen, and potassium. In its pure form, it is white and crystalline in appearance. It is the most common chlorate used in industry, school, research, and commercial labs. Potassium chlorate is commonly used: to prepare oxygen, in safety matches, as an oxidizing agent, in fireworks and

    • 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 Lights Work

      How Traffic Lights Work

      Traffic lights are basically signalling lights placed at crossroads or turning-points to regulate the flow of vehicular traffic. This system is of utmost importance specially in populated traffic zones to avoid accidents and human casualties. That is most cities deploy traffic signals on every road. Less traffic oriented areas in villages and country side may

    • What is Mars Made Of?

      What is Mars Made Of?

      The planet Mars has held a place of intrigue with humanity for many centuries. Also known as the “Red Planet,” Mars can be seen with the naked eye and looks red due to the large red desert covering its surface and the presence of a large amount of ferric oxide. As the fourth planet in

    • What is Luminous Flux?

      What is Luminous Flux?

      Luminous flux (luminous power) is the measurement of the (perceived) power of light. It is adjusted to take the human eye’s sensitivity to the different wavelengths of light into account. Luminous flux differs from radiant flux in this manner, since radiant flux is a measurement of the total power of light emitted independent of wavelength.

    • Driverless Cars

      Driverless Cars

      A driverless car (also autonomous/autopilot/auto-drive car) refers to a car that does not need human intervention to function. The first driverless car achieved a maximum speed of 20 miles-per-hour and was built by Tsukuba Mechanical Engineering Laboratory in 1977. The Mercedes Benz robot van built during the 1980s achieved a full speed of 60 miles-per-hour

    • 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

    • How a Space Station Works

      How a Space Station Works

      What was once only a dream has now become a reality as space travel is a regular activity in our society. With thousands of satellites in orbit, the Hubble Space Telescope that can see other galaxies, regular shuttle launches, and prototypes for vehicles that can fly in and out of the atmosphere, it makes sense

    • Angular Acceleration

      Angular Acceleration

      Angular acceleration is the rate of change of a body’s angular velocity compared to time. It is considered a vector quantity since it has a direction and magnitude. Angular acceleration is similar to linear acceleration except that it travels on an arc. Scientifically, it is equal to (final angular velocity – initial angular velocity) /
