The AA is the largest motoring organization in the United Kingdom that provides services such as breakdown assistance and motorist insurance. For a number of years, only AA members could take advantage of the company’s route planning services by picking up paper maps and routes from the organization’s local office. The AA now provides free online route planning for consumers on their website’s AA route planner. The online service allows drivers to plan multi-leg trips across the United Kingdom, Ireland, and Europe, and has a number of features that can Read More

A magnetic separator is a device that uses a magnet to remove impurities and other magnetic materials from metal. Magnetic separators can be used before, during, and after production of a material and can be adjusted to attract different types of magnetic materials at varying levels of intensity. Magnetic separators are used for a wide variety of applications, though their use is almost always industrial in nature. Magnetic separators can be either ferromagnetic or paramagnetic and can range in size from a tabletop version to a large, heavy drum that Read More

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. For What Purpose is a Nuclear Bone Scan Used? There are several ways that a nuclear bone scan can be used. In general, bone scans are an excellent tool for identifying and evaluating damage to Read More

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 are placed in locations where there are complex intersections, traffic congestion, or locations with weather hazards. The cameras used for such purposes are digital and transmit low resolution pictures from a pole usually about 30 Read More

As science is beginning to move towards terraforming, a process that converts a “dead” planet into a thriving environment for life, the question of “How was the Earth formed?” comes to mind. Unfortunately, there is no exact answer when it comes to the formation of the Earth as no one was around back then to record it. Religion claims that God created the Earth in seven days several thousand years ago while science says that evolution, natural selection, and physics created the Earth billions of years ago. As religious claims Read More

The different nuclear processes will use different types of fuel. In general terms: Fission reactions will use fissile heavy elements Fusion will use fusible light elements The convection point is iron. Elements heavier that iron will have higher mass than its parts and yield energy when they break apart. Lighter elements that iron will have less mass than its parts giving away energy when they fusion. Very unstable substances will not be useful, they need to be stable under normal conditions but become unstable when bombarded with neutrons. Special isotopes Read More

A laser sight is a device that shoots a laser at a certain target. It is often used within many military applications, especially with guns. Basically, the laser sight is a visible laser light that allows the shooter to see where the bullet will hit. It is located (or structured to fit) above the body of the small arm at a precise angle facing down, so that the laser will point directly at the spot where the bullet will most likely hit. However, as with all devices, the laser is Read More

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 the solar system, and final one before the asteroid belt, a common question that arises amongst students and adults is what is Mars made of? Is Mars Made of Similar Material to Earth? The basic Read More

The Inverse Square Law is a physics law that states that a strength or quantity is inversely proportional to the square of the distance from the source of the strength or quantity. In more technical terms, a vector field divergence that is a result of the radial inverse square law fields with one or many sources, is proportional to the strength of the local sources and no outside sources. What is the Justification for the Inverse Square Law? The inverse square law applies whenever an energy, force, or conserved quantity Read More

DNA fingerprinting is the process of taking a cell sample from a person and analyzing it. This technique involves analyses of less than 0.1% of human DNA (which is different for each person). Though small, this 0.1% of DNA is enough to distinguish one individual from another and can be used to determine maternity/ paternity or the identity of a person, whether dead or alive. DNA fingerprinting should not be confused with the traditional idea of fingerprinting (making an imprint of a person’s fingerprints in ink). What is DNA? Every Read More
