A fishing rod is a long, elastic rod used by fishermen to catch fish by manipulating a line ending in a hook. At its simplest form, a fishing rod is a straight stick or pole with a line attached to one end, but modern rods generally have the line stored on a reel mounted at the rod handle, which controls the line retrieval, as well as line-guiding swivels that reduce tangling. To better entice fish, bait or lures are dressed on the one or more hooks attached to the line, and a bite indicator is used, some of which might be incorporated as part of the rod itself.
Dowsing is a type of divination employed in attempts to locate ground water, buried metals or ores, gemstones, oil, claimed radiations (radiesthesia), gravesites, malign 'earth vibrations' and many other objects and materials without the use of a scientific apparatus. It is also known as divining ), doodlebugging or water finding, or water witching.

Matteucci effect is one of the magnetomechanical effects, which is thermodynamically inverse to Wiedemann effect. This effect was described by Carlo Matteucci in 1858. It is observable in amorphous wires with helical domain structure, which can be obtained by twisting the wire, or annealing under twist. The effect is most distinct in the so-called 'dwarven alloys', with cobalt as main substituent.
The twisting of a ferromagnetic rod through which an electric current is flowing when the rod is placed in a longitudinal magnetic field. It was discovered by the German physicist Gustav Wiedemann in 1858 . The Wiedemann effect is one of the manifestations of magnetostriction in a field formed by the combination of a longitudinal magnetic field and a circular magnetic field that is created by an electric current. If the electric current is alternating, the rod will begin torsional oscillation.
A photoreceptor cell is a specialized type of neuroepithelial cell found in the retina that is capable of visual phototransduction. The great biological importance of photoreceptors is that they convert light into signals that can stimulate biological processes. To be more specific, photoreceptor proteins in the cell absorb photons, triggering a change in the cell's membrane potential.
The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple. A thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, heat is transferred from one side to the other, creating a temperature difference. At the atomic scale, an applied temperature gradient causes charge carriers in the material to diffuse from the hot side to the cold side.
Levelling or leveling is a branch of surveying, the object of which is to establish or verify or measure the height of specified points relative to a datum. It is widely used in geodesy and cartography to measure geodetic height, and in construction to measure height differences of construction artifacts. It is also known as spirit levelling and differential levelling.
The Harrington rod is a stainless steel surgical device. Historically, this rod was implanted along the spinal column to treat, among other conditions, a lateral or coronal-plane curvature of the spine, or scoliosis. Up to one million people had Harrington rods implanted for scoliosis between the early 1960s and the late 1990s.
Intrinsically photosensitive retinal ganglion cells (ipRGCs), also called photosensitive retinal ganglion cells (pRGC), or melanopsin-containing retinal ganglion cells (mRGCs), are a type of neuron in the retina of the mammalian eye. The presence of ipRGCs was first suspected in 1927 when rodless, coneless mice still responded to a light stimulus through pupil constriction, suggesting that rods and cones are not the only light-sensitive neurons in the retina. It wasn't until the 1980s that advancements in research on these cells began. Recent research has shown that these retinal ganglion cells, unlike other retinal ganglion cells, are intrinsically photosensitive due to the presence of melanopsin, a light-sensitive protein. Therefore they constitute a third class of photoreceptors, in addition to rod and cone cells.
The Chernobyl disaster was a nuclear accident that occurred on 26 April 1986 at the No. 4 reactor in the Chernobyl Nuclear Power Plant, near the city of Pripyat in the north of the Ukrainian SSR in the Soviet Union. It is considered the worst nuclear disaster in history both in cost and casualties. It is one of only two nuclear energy accidents rated at seven—the maximum severity—on the International Nuclear Event Scale, the other being the 2011 Fukushima nuclear disaster in Japan. The initial emergency response, together with later decontamination of the environment, involved more than 500,000 personnel and cost an estimated 18 billion Soviet rubles—roughly US$68 billion in 2019, adjusted for inflation.
The Time Machine is a 1960 American period science fiction film in Metrocolor from Metro-Goldwyn-Mayer. It was produced and directed by George Pal and stars Rod Taylor, Yvette Mimieux, and Alan Young. The film was based on the 1895 novella of the same name by H. G. Wells that was influential on the development of science fiction.
The lilac chaser is a visual illusion, also known as the Pac-Man illusion. It consists of 12 lilac, blurred discs arranged in a circle, around a small black, central cross on a grey background. One of the discs disappears briefly, then the next, and the next, and so on, in a clockwise direction. When one stares at the cross for about 5 seconds or so, one sees three different things:
A quiver tip is a flexible extension to a fishing rod which is designed to vibrate, or quiver, when a fish takes the bait. The main characteristic of its design is its sensitivity. It is a popular and very effective method of bite indication both on still and running water, and is used far more often in bottom fishing. It is not used in game fishing and is seldom, if ever, used when fishing for very large coarse fish. In essence, the angler watches the tip of the fishing rod to detect bites as opposed to, say, a float or an electronic bite alarm.
Two Evil Eyes is a 1990 anthology horror film written and directed by George A. Romero and Dario Argento. An international co-production of Italy and the United States, Two Evil Eyes is split into two separate tales, both based largely on the works of Edgar Allan Poe: "The Facts in the Case of M. Valdemar", directed by Romero and starring Adrienne Barbeau; and "The Black Cat", directed by Argento and starring Harvey Keitel, which blends a number of Poe references into a new narrative. Both of the tales were filmed and take place in contemporary Pittsburgh.
Etonogestrel is a medication which is used as a means of birth control for women. It is available as an implant placed under the skin of the upper arm under the brand names Nexplanon and Implanon, and in combination with ethinylestradiol, an estrogen, as a vaginal ring under the brand names NuvaRing and Circlet. Etonogestrel is effective as a means of birth control within 8 hours of insertion and lasts at least three or four years with some data showing effectiveness for five years. Following removal, fertility quickly returns.
The Fender Hot Rod DeVille is a combo tube guitar amplifier manufactured and sold by Fender. It was introduced in 1996 as part of Fender's Hot Rod line of amplifiers, and since then has been in continuous production. The Hot Rod DeVille is a modified version of the earlier Fender Blues DeVille from the Blues amplifier line, and has a higher level of gain in its preamplification signal. The DeVille incorporates a 60 watt amplifier, and is available in two different models: a 212, which includes a pair of Celestion A-Type 12" speakers, and the 410, which includes four 10" speakers. The DeVille is the sister amplifier of the Fender Hot Rod Deluxe.
A lightning rod or lightning conductor (UK) is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. If lightning hits the structure, it will preferentially strike the rod and be conducted to ground through a wire, instead of passing through the structure, where it could start a fire or cause electrocution. Lightning rods are also called finials, air terminals, or strike termination devices.
In pharmacology, pleiotropy includes all of a drug's actions other than those for which the agent was specifically developed. It may include adverse effects which are detrimental ones, but is often used to denote additional beneficial effects.
A boomkicker is a modern mechanical device on boats that pushes the boom up by one or more glassfiber rods. If the boom is sheeted in, the rods will bend and produce a force upwards.
