George P. Metesky
George Peter Metesky (November 2, 1903 – May 23, 1994), better known as the Mad Bomber, was an American electrician and mechanic who terrorized New York City for 16 years in the 1940s and 1950s with explosives that he planted in theaters, terminals, libraries and offices. Bombs were left in phone booths, storage lockers and restrooms in public buildings, including Grand Central Terminal, Pennsylvania Station (New York City), Pennsylvania Station, Radio City Music Hall, the New York Public Library, the Port Authority Bus Terminal and the RCA Building, and in the New York City Subway. Metesky also bombed movie theaters, where he cut into seat upholstery and slipped his explosive devices inside. Angry and resentful about events surrounding a workplace injury suffered years earlier, Metesky planted at least 33 bombs, of which 22 exploded, injuring 15 people. The hunt for the bomber enlisted an early use of offender profiling. He was apprehended in 1957 based on clues given in let ...

Offender Profiling
Offender profiling, also known as criminal profiling, is an investigative strategy used by law enforcement agencies to identify likely suspects and has been used by investigators to link cases that may have been committed by the same perpetrator. Multiple crimes may be linked to a specific offender and the profile may be used to predict the identified offender's future actions. In the 1980s, most researchers believed offender profiling was relevant only to sex crimes, like serial rape or sexual homicide, but since the late 1990s research has been published to support its application to arson (1998), and then later terrorism (2000) and burglary (2017). Theory Psychological profiling is described as a method of suspect identification which seeks to identify a person's mental, emotional, and personality characteristics based on things done or left at the crime scene. There are two major assumptions made when it comes to offender profiling: behavioral consistency and homology. Beha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pocket Watch
A pocket watch (or pocketwatch) is a watch that is made to be carried in a pocket, as opposed to a watch, wristwatch, which is strapped to the wrist. They were the most common type of watch from their development in the 16th century until wristwatches became popular after World War I during which a transitional design, trench watches, were used by the military. Pocket watches generally have an attached chain to allow them to be secured to a waistcoat, lapel, or belt (clothing), belt loop, and to prevent them from being dropped. Watches were also mounted on a short leather strap or fob, when a long chain would have been cumbersome or likely to catch on things. This fob could also provide a protective flap over their face and crystal. Women's watches were normally of this form, with a watch fob that was more decorative than protective. Chains were frequently decorated with a silver or Vitreous enamel, enamel pendant, often carrying the arms of some Club (organization), club or s ...

Flashlight
A flashlight ( US, Canada) or torch ( UK, Australia) is a portable hand-held electric lamp. Formerly, the light source typically was a miniature incandescent light bulb, but these have been displaced by light-emitting diodes (LEDs) since the mid-2000s. A typical flashlight consists of the light source mounted in a reflector, a transparent cover (sometimes combined with a lens) to protect the light source and reflector, a battery, and a switch, all enclosed in a case. The invention of the dry cell and miniature incandescent electric lamps made the first battery-powered flashlights possible around 1899. Today, flashlights use mostly light-emitting diodes and run on disposable or rechargeable batteries. Some are powered by the user turning a crank, shaking the lamp, or squeezing it. Some have solar panels to recharge the battery. Flashlights are used as a light source outdoors, in places without permanently installed lighting, during power outages, or when a portable light sourc ...

Timer
A timer is a specialized type of clock used for measuring specific time intervals. Timers can be categorized into two main types. The word "timer" is usually reserved for devices that counts down from a specified time interval, while devices that do the opposite, measuring elapsed time by counting upwards from zero, are called stopwatches. A simple example of the first type is an hourglass. Working method timers have two main groups: hardware and software timers. Most timers give an indication that the time interval that had been set has expired. Time switches, timing mechanisms that activate a switch, are sometimes also called "timers". Hardware Mechanical Mechanical use clockwork to measure time. Manual timers are typically set by turning a dial to the time interval desired; turning the dial stores energy in a mainspring to run the mechanism. They function similarly to a mechanical alarm clock; the energy in the mainspring causes a balance wheel to rotate back and forth. ...

Pipe Bomb
A pipe bomb is an improvised explosive device which uses a tightly sealed section of pipe (material), pipe filled with an explosive material. The containment provided by the pipe means that simple Explosive material#Low explosives, low explosives can be used to produce a relatively huge explosion due to the containment causing increased pressure, and the fragmentation of the pipe itself creates potentially lethal Fragmentation (weaponry), shrapnel. Premature detonation is a hazard of attempting to construct any homemade bomb, and the materials and methods used with pipe bombs make unintentional detonation incidents common, usually resulting in serious injury or death to the assembler. In many countries, the manufacture or possession of a pipe bomb is a serious crime, regardless of its intended use. Design The bomb is usually a short section of steel water pipe containing the explosive mixture and closed at both ends with steel or brass caps. A fuse is inserted into the pipe ...

Power Station
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and an increasing use of renewables such as solar, wind, geothermal, and hydroelectric. History In early 1871 Belgian inventor Zénobe Gramme invented a generator powerful enough to produce power on a commercial scale for industry. In 1878, a hydroelectric power station was designed and built b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrician
An electrician is a tradesperson specializing in electrical wiring of buildings, transmission lines, stationary machines, and related equipment. Electricians may be employed in the installation of new electrical components or the maintenance and repair of existing electrical infrastructure. Electricians may also specialize in wiring ships, airplanes, and other mobile platforms, as well as data and cable lines. Terminology ''Electricians'' were originally people who demonstrated or studied the principles of electricity, often electrostatic generators of one form or another. In the United States, electricians are divided into two primary categories: lineperson, who work on electric utility company distribution systems at higher voltages, and wiremen, who work with the lower voltages utilized inside buildings. Wiremen are generally trained in one of five primary specialties: commercial, residential, light industrial, industrial, and low-voltage wiring, more commonly known a ...
