    • What is Malleability?

      What is Malleability?

      Malleability refers to metals’ (and other hard materials’) ability to be stretched, shaped, or molded through applied pressure. While not all objects are malleable, most metals are. This is the reason that metals such as gold, silver, and platinum, are used to make jewelry and electronic circuits. Malleable objects can usually be reshaped and molded

    • How Does an Ultrasonic Nebulizer Work?

      How Does an Ultrasonic Nebulizer Work?

      An ultrasonic nebulizer is a small, portable device that uses ultrasonic sound waves to break liquid particles down into a fog so that they can be inhaled easily. Patients who have asthma, COPD, pneumonia, chronic bronchitis, emphysema, or other chronic conditions, most often use them for medicinal purposes. While other devices can deliver the medicine

    • What Are Permanent Magnets?

      What Are Permanent Magnets?

      A permanent magnet (ferromagnet) is a material that produces a magnetic field. Permanent magnets are made from ferromagnetic materials, such as iron, and are created when the material is placed inside of a magnetic field. When the magnetic field is removed, the object remains magnetized. Permanent magnets have a permanent magnetic field and do not

    • 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

    • What Are Subatomic Particles?

      What Are Subatomic Particles?

      Subatomic particles are the most elementary particles found in nature. The three basic subatomic particles that comprise an atom are protons, electrons, and neutrons. The historical definition of a subatomic particle was expanded over the past several decades to include elementary particles that are less complex than an atom and cannot be broken down further.

    • 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

    • Holographic Memory

      Holographic Memory

      Holographic memory is a storage device that is being researched and slated as the storage device that will replace hard drives and DVDs in the future. It has the potential of storing up to 1 terabyte or one thousand gigabytes of data in a crystal the size of a sugar cube. Brief History of Holographic

    • ESR Spectroscopy

      ESR Spectroscopy

      ESR Spectroscopy (Electron Spin Resonance Spectroscopy or Electron Paramagnetic Resonance Spectroscopy) is a technique used for studying chemical species that have one or more “free radical” or unpaired electrons. Most stable molecules only have paired electrons without any free radicals, so ESR Spectroscopy is used less often than NMR (Nuclear Magnetic Resonance) Spectroscopy, the usual

    • Who Discovered Quantum and Particle Physics?

      Who Discovered Quantum and Particle Physics?

      During the nineteenth century the main theory in physics was still Newtonian Mechanics. With the advances in electricity, magnetism and the studies about light, it was clear that the theory had its limitations. The limitations appeared in the limits of the too small (atomic size) or the too fast (light speed). The study of the

    • How Does a Segway Work?

      How Does a Segway Work?

      A Segway is a vertical, mobile vehicle that is able to carry a single person between distances. While a bicycle consists of two wheels and a horizontal frame, a Segway consists of two or four wheels and a vertical frame that balances atop these wheels to steady the rider. Segways run on purely electrical energy
