Angular acceleration is the rate of change of a body's angular velocity compared to time. It is considered a vector quantity since it has a direction and magnitude. Angular acceleration is similar to linear acceleration except that it travels on an arc. Scientifically, it is equal to (final angular velocity – initial angular velocity) / time. A body's angular velocity is the rate of change of angular distance with respect to time and acceleration is the rate of this change over the same time f

What is Fingerprint Identification?
Fingerprint identification is the process of using fingerprints to identify an individual. This is very effective because each person has completely unique fingerprints that do not change with age. Fingerprint identification is used for a variety of reasons: security, criminal investigations, and even ergonomics. Fingerprint identification often consists of a fingerprint reader or oil smear, with the former being used in electronic fingerprinting and the lat

Stem cells have been widely publicized over the last decade as being the key to huge health breakthroughs. While only time will tell just how stem cells will be used in the future, millions of people around the world are either involved in stem cell research or closely monitor it for news of advances.
What are Stem Cells?
Stem cells are found in practically all multi-cellular organisms. Their defining characteristic is that they are able to renew themselves, usually through a process of mitoti

Casting is a mass production process which involves molten materials (such as metals, plastics or resins) being poured into a mold, allowed to solidify and then extracted for use. Casting can be thought of as a method for reproducing something - whether a mere part or a single unit by itself.
Casting is a process that can be used to manufacture complex parts which would prove too expensive or time-consuming to produce using other methods such as cutting or shaping these from solid materials.

Metal detector technology has been used for a number of decades to locate various metallic artifacts and precious metallic ores. An uncommon, but accurate metal detector is the Pulse Induction Metal Detector. It uses Pulse Induction Technology to find metals.
What is Pulse Induction Technology?
In Pulse Induction technology, a coil is used as a transmitter and receiver. Pulse Induction metal detectors are likely to have a single coil, but there are others that have additional coils. Powerf

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 repair work is completed, or it gives incorrect readings on a consistent basis.
When Were Speedometers First Used?
Automobile manufacturers first included Spe

A Virtual Autopsy or Virtopsy is a new and non-intrusive form of performing an human autopsy. This system utilizes a Computer Tomography or CT unit and an (MRI) Magnetic Resonance Imaging unit to obtain a detailed view of a body. Here the MRI images and the detailed X-rays are combined to create a full three-dimensional view of the body which medical examiners, coroners and pathologists can use to examine the state of the blood vessels, organs, bones and tissues of a body and thus determine the

A geosynchronous orbit is when a satellite or other device's orbit matches the Earth's rotation so that the satellite travels around the Earth in a straight line and stays at the same point in the sky relative to the Earth. This means that as the Earth rotates, the satellites rotates around the Earth at the same speed so that its relative position never changes. Geosynchronous orbits are used for a number of purposes, including monitoring a specific region and communicating with Earth-base

While many of us labored to learn geography in school, we always wondered why it mattered. Here are some reasons why a sound understanding of geography is more important today than ever before.
Politics
We live in a world that is shaped by the political climate in various locations around the globe. In order to understand the mindset of modern day politicians, we can often get valuable clues by looking at the present geography of the country, state, or province they serve. At some point in tim
