      What Are the Four Dimensions?

      The four dimensions are concepts in mathematics to describe different shapes. It is easy to understand a first dimension, second dimension and third dimension shape. All things are 3D in the world, but images can be 2D. A first dimension is as easy as a line. However, what is the fourth dimension? The fourth dimension

    • What is a Plastic Injection Molding Machine?

      What is a Plastic Injection Molding Machine?

      A plastic injection molding machine or injection press is a device that melts plastics and materials made from other polymers, and injects them into a mold. Plastic injection molding machines are most often used to recycle plastic, but are also the primary device responsible for producing plastic objects in the first place. They use a

    • What Happens During Photosynthesis?

      What Happens During Photosynthesis?

      Photosynthesis is the process that plants, some bacteria, and some animals use to convert light energy and other sources into sugar and other essential proteins that they need to survive. This article will go over how photosynthesis works and the many different aspects of this process. We will talk about photosynthetic membranes, light reactions, solar

    • Brookfield Viscometer

      Brookfield Viscometer

      The Brookfield Viscometer makes it possible to measure viscosity by employing techniques in viscometry. Viscometers (which can also be called viscosimeters) can measure viscosity through the varying flow conditions of the sample material being tested. They employ a spindle on a shaft that is designed to be dipped or immersed into a liquid that is

    • Magnetorheological Fluid

      Magnetorheological Fluid

      Magnetorheological fluid or MR fluid is a special material used for building smart structures that can withstand earthquakes. The Magnetorheological fluid can change from liquid to solid and vice versa. It makes the buildings of which it is a component particularly flexible so they can adapt to external force that would have made other more

      How Do Oil Rigs Work?

      As recent events concerning oil spills in multiple locations have flooded the news, many people are wondering how oil drilling works and why something like an oil spill can happen. This article will attempt to answer these questions by explaining how the various processes of oil drilling work. What is an Oil Rig An oil

    • How a Nuclear Bone Scan Works

      How a Nuclear Bone Scan Works

      In the last several decades, medical technology has advanced in leaps and bounds. One of the most advanced technological instruments used in medicine today is the nuclear bone scan. A nuclear bone scan uses a radioactive tracer and high-resolution camera to identify areas of new bone growth or areas in which bone has broken down.

    • 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

    • Long Range Acoustic Device

      Long Range Acoustic Device

      The LRAD or the long range acoustic device that has been developed by American Technology Corporation is capable of emitting a maximum of 151Db sound within 30 degrees of where the device is pointing. This device can be used as a combatant deterrent weapon or crowd-control device by emitting sounds that are painful to the

    • What is an Ultrasonic Fogger?

      What is an Ultrasonic Fogger?

      An ultrasonic fogger is a device that uses ultrasonic sound waves to break water into millions of individual water droplets that are then sprayed into the air as a thick fog. Ultrasonic foggers are most often used for Halloween decorations as a dry ice replacement. The fog that an ultrasonic fogger produces is not created
