Isodynamic point
In Euclidean geometry, the isodynamic points of a triangle are points associated with the triangle, with the properties that an inversion centered at one of these points transforms the given triangle into an equilateral triangle, and that the distances from the isodynamic point to the triangle vertices are inversely proportional to the opposite side lengths of the triangle. Triangles that are similar to each other have isodynamic points in corresponding locations in the plane, so the isodynamic points are triangle centers, and unlike other triangle centers the isodynamic points are also invariant under Möbius transformations. A triangle that is itself equilateral has a unique isodynamic point, at its centroid(as well as its orthocenter, its incenter, and its circumcenter, which are concurrent); every non-equilateral triangle has two isodynamic points. Isodynamic points were first studied and named by Joseph Neuberg (1885).

Equilateral triangle
An equilateral triangle is a triangle in which all three sides have the same length, and all three angles are equal. Because of these properties, the equilateral triangle is a regular polygon, occasionally known as the regular triangle. It is the special case of an isosceles triangle by modern definition, creating more special properties.

The equilateral triangle can be found in various tilings, and in polyhedrons such as the deltahedron and antiprism. It appears in real life in popular culture, architecture, and the study of stereochemistry resembling the molecular known as the trigonal planar molecular geometry.
OPR-1000
The OPR-1000 is a South Korean-designed two-loop 1000 MWe PWR Generation II nuclear reactor, developed by KHNP and KEPCO. The OPR-1000 was originally designated as the Korean Standard Nuclear Power Plant (KSNP), and was re-designated as the OPR-1000 in 2005 for foreign sales.  It was developed based  on the Combustion Engineering (C-E)'s system 80 design, through a technology transfer agreement. The reactor core design was derived from the C-E designed Arkansas Nuclear One Unit 2, the nuclear steam supply system (NSSS) was derived from the C-E designed units at Palo Verde Nuclear Generating Station, and auxiliary plant design was derived from the earlier Unit-1 and Unit-2 at the Yeonggwang (now Hanbit) Nuclear Power Plant.

Based on the OPR-1000 design, KEPCO has developed a Generation III reactor uprated plant, the APR-1400.

Korea Hydro & Nuclear Power
Korea Hydro & Nuclear Power (KHNP; Korean: 한국수력원자력) is a subsidiary of the Korea Electric Power Corporation (KEPCO). It operates large nuclear and hydroelectric plants in South Korea, which are responsible for about 31.56 percent of the country's electric power.

Polymer chemistry
Polymer chemistry is a sub-discipline of chemistry that focuses on the structures, chemical synthesis, and chemical and physical properties of polymers and macromolecules. The principles and methods used within polymer chemistry are also applicable through a wide range of other chemistry sub-disciplines like organic chemistry, analytical chemistry, and physical chemistry. Many materials have polymeric structures, from fully inorganic metals and ceramics to DNA and other biological molecules. However, polymer chemistry is typically related to synthetic and organic compositions. Synthetic polymers are ubiquitous in commercial materials and products in everyday use, such as plastics, and rubbers, and are major components of composite materials. Polymer chemistry can also be included in the broader fields of polymer science or even nanotechnology, both of which can be described as encompassing polymer physics and polymer engineering.

Synthetic rubber
A synthetic rubber is an artificial elastomer. They are polymers synthesized from petroleum byproducts. About 32 million tonnes (35 million short tons; 31 million long tons) of rubber is produced annually in the United States, and of that amount two thirds are synthetic. Synthetic rubber, just like natural rubber, has many uses in the automotive industry for tires, door and window profiles, seals such as O-rings and gaskets, hoses, belts, matting, and flooring. They offer a different range of physical and chemical properties which can improve the reliability of a given product or application. Synthetic rubbers are superior to natural rubbers in two major respects: thermal stability, and resistance to oils and related compounds.  They are more resistant to oxidizing agents, such as oxygen and ozone which can reduce the life of products like tires.

2025 Taipei stabbings
On 19 December 2025, 27-year-old Chang Wen (Chinese: 張文) threw smoke grenades and stabbed people at two locations in Taipei, Taiwan, killing three people and injuring eleven others. Chang Wen fled from police and died when he fell from the Eslite Bookstore Nanxi building near Zhongshan Station.

Smoke grenade
A smoke grenade is a canister-type grenade used as a signaling device, target or landing zone marking device, or as a screening device for unit movements.

Smoke grenades are generally more complex and emit a far larger amount of smoke than smoke bombs, which are a type of firework typically started with an external fuse rather than a pin. Smoke grenades often cost around US$40 compared to smoke bombs, which can often cost just a few cents. The phrase "to smoke", meaning to fake, bluff, or beat around the bush, comes from the military usage of smoke grenades to obscure and conceal movement; similarly, "pop smoke", derived from a common way of ordering the use of smoke grenades, is used as a slang term for quickly leaving a place.

Doppler radar
A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal. This variation gives direct and highly accurate measurements of the radial component of a target's velocity relative to the radar. The term applies to radar systems in many domains like aviation, police radar detectors, navigation, meteorology, etc.
