      Fingerprint Identification

      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

    • Driverless Cars

      Driverless Cars

      A driverless car (also autonomous/autopilot/auto-drive car) refers to a car that does not need human intervention to function. The first driverless car achieved a maximum speed of 20 miles-per-hour and was built by Tsukuba Mechanical Engineering Laboratory in 1977. The Mercedes Benz robot van built during the 1980s achieved a full speed of 60 miles-per-hour

    • What Causes Radioactivity?

      What Causes Radioactivity?

      Radioactivity is caused when an atom, for whatever reason, wants to give away some of its energy. It does this because it wants to shift from an unstable configuration to a more stable configuration. The energy that is released when the atom makes this shift is known as radioactivity. In other words, radioactivity is the

    • Air Circulators

      Air Circulators

      An air circulator is basically a fan. Although the term “air circulator” most often refers to an industrial fan that is used in a warehouse, factory, or office building, it can also refer to a regular household fan. Air circulators also refer to air conditioning units and other types of air cooling devices. They are

    • How Laser Skin Treatment Works

      How Laser Skin Treatment Works

      A laser skin treatment is a relatively new technology that surgeons have only recently begun using. It is when the surgeons utilize lasers (containing carbon dioxide) to vaporize the skin’s upper layers, consequently allowing a new layer of skin to form. The technique is commonly used to fine tune wrinkles and various face lines, especially

    • 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

    • How Do Oil Rigs Work?

      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

    • 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

    • 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,

    • What Causes Copper to Turn Green?

      What Causes Copper to Turn Green?

      Copper turns green because of a process known as oxidation which is the removal of electrons from the substance. Specifically, copper turns green because of something known as copper carbonate. This is the substance that is found on top of copper–whether they be copper pipes, pennies, statues or anything else. So, the cause of copper
