      Rail Guns

      Rail guns are weapons that use electrical current instead of gunpowder to propel their projectiles. A projectile is any object thrust into accelerated motion with the influence of force. Projectiles in motion can be propelled by pushes, pulls or, in some cases, both push and pull. The armaments and weapons industry's continuous development has had

    • What is a Laser Profilometer?

      What is a Laser Profilometer?

      A profilometer is an instrument that measures a surface profile to determine its roughness. A surface’s vertical resolution is normally measured at the nanometer level, with lateral resolutions being measured to a less accurate degree. Over the past decade, profilometers have started using laser technology in order to improve the degree to which a surface

    • How a Convection Oven Works

      How a Convection Oven Works

      In a regular oven, a thin layer of air insulates food from the heat beneath it. This layer of air causes food to be cooked unevenly and slows cooking time down considerably. A convection oven is a type of oven that solves this problem by circulating the air within the chamber by using either one

    • Laser Distance Measurement

      Laser Distance Measurement

      For the past two decades, lasers have been used to measure distance without having to physically touch the area or things being measured. Laser measurement is capable of very precise and quick distance measurements. Lasers have been used in military targeting, criminal investigations, and sports. As research has progressed, the size of laser measuring devices

    • What is the Fifth State of Matter?

      What is the Fifth State of Matter?

      The fifth state of matter is actually the first phase of matter. It is called a Bose-Einstein Condensate. Matter in the fifth state is really slow moving and extremely condensed. It only exists at near absolute zero temperatures and is very fragile and unstable. It was discovered in 1995 by Eric Cornell and Carl Weiman through experimentation with rubidium,

    • Boltzmann Constant

      Boltzmann Constant

      The Boltzmann Constant (Boltzmann’s Constant) is a fundamental physics constant that plays a pivotal role in almost every single statistical formulation in both quantum and classical physics. It is named after Austrian physicist, Ludwig Boltzmann (1844 – 1906), who made significant contributions to the foundation and development of a particular branch of theoretical physics known

    • What Are Nanorobots?

      What Are Nanorobots?

      A nanobot is an extremely small robot that operates on a microscopic scale. Originally spoken of in science fiction circles, there has been an increased focus on it in biological and robotics research. The term nanorobot was created by combining the terms robot and nanometer. Other common names for robots of this size include nanobots,

    • Magnetic Levitation

      Magnetic Levitation

      Magnets are mainly characterized for having poles: if you put together poles of the same charge they repel and if you put together charges of different pole, they attract. A body will be under Magnetic Levitation when it floats due to that special repelling quality of the magnets, i.e. when the force generated by the

    • 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

    • Liquid Armor

      Liquid Armor

      Liquid armor is a new development in the body armor field. It is a material that makes lightweight, flexible and tough body armors possible. Body Armor Body armor is a protective clothing designed to stop bullets or bomb fragments and shrapnel from penetrating the human body. They are descended from leather or metal armor designed
