      Electromotive Force

      Electromotive force is the electrical potential energy that causes current to flow through a circuit. It results from the difference in charge between two points in a material. This difference is created when an external source such as a battery makes electrons move to both points so that there is an excess at the first

    • Weather Modification Technology

      Weather Modification Technology

      Weather modification refers to willful manipulation of the climate or local weather. Research done in this field goes back to as far as the early 1940s when the US military experimented with cloud seeding to stimulate rain. Today, private corporations have joined the weather modification research effort to protect people, cities and assets from the

    • Nanotubes


      A nanotube is a cylinder made up of atomic particles and whose diameter is around one to a few billionths of a meter (or nanometers). They can be made from a variety of materials. Nanotubes are believed to be stronger than steel, but more flexible than plastic, and they also exhibit excellent thermal and electrical conductivity. These

    • What Causes Optical Illusions?

      What Causes Optical Illusions?

      In simple terms, an optical illusion is caused by the structure of both the eye and brain and how they work together. Because of the anatomical make up of the eye and the complexity of the way images of transmitted from the eye to the brain, optical illusions are not as rare as one might

    • What Causes Volcanoes?

      What Causes Volcanoes?

      A volcano is typically found where two or  more tectonic plates are either converging or diverging. The result is a rupture in the surface of the planet which then allows hot ashes, gas, and volcanic lava to rise up from the magma chamber located underneath the Earth’s surface to the atmosphere. Some of the common

    • Speedometer Calibration

      Speedometer Calibration

      One of the most prominent gauges on an automobile’s dashboard is the speedometer. Its primary function is to give a visual indication of a vehicle’s speed in miles or kilometers (or both) per hour. Since the majority of these devices are still analog, they may require speedometer calibration when new tires are installed, major automotive

    • What Causes Typhoons?

      What Causes Typhoons?

      A typhoon is nothing more than a hurricane that occurs in the North West Pacific Ocean. The same conditions that cause a hurricane in the Atlantic ocean that hit the United States every summer are the ones that cause a typhoon. However, a typhoon does have a series of specific “rules” to exist and therefore,

    • Vulcanized Rubber

      Vulcanized Rubber

      Vulcanized rubber is a material that undergoes a chemical process known as vulcanization. This process involves mixing natural rubber with additives such as sulfur and other curatives. Vulcanization makes rubber much stronger, more flexible, and more resistant to heat and other environmental conditions. Vulcanized rubber makes both soft and hard objects, ranging from rubber bands

    • Terahertz Radiation

      Terahertz Radiation

      Terahertz radiation is a selection of the electromagnetic wave spectrum that propagates at frequencies regarded as the terahertz band. ‘Radiation physics of energetic waves’ defines the terahertz band as tremendously high frequency. The terahertz band can be applied within the bracket of 300 gigahertz (high frequency microwave) and 3000 gigahertz (long wavelength far infrared light).

    • Mannitol Salt Agar

      Mannitol Salt Agar

      In order to grow a bacterial culture in a lab, a growth medium has to be used to provide the right environment. Mannitol salt agar is a popular bacterial growth medium that biologists use to grow halphile bacteria (these grow fast in high salt concentrations) and can tell the difference between non-pathogenic and pathogenic Staphylococcus
