Light front quantization
The light-front quantization
of quantum field theories
provides a useful alternative to ordinary equal-time 
quantization.  In
particular, it can lead to a relativistic description of bound systems
in terms of quantum-mechanical wave functions.  The quantization is
based on the choice of light-front coordinates,
where  plays the role of time and the corresponding spatial coordinate is .  Here,  is the ordinary time, 
is one Cartesian coordinate, and  is the speed of light.  The other two Cartesian coordinates,  and , are untouched and often called transverse or perpendicular, denoted by symbols of the type 
.  The choice of the frame of reference where the time
 and -axis are defined can be left unspecified in an exactly soluble relativistic theory, but in practical calculations some choices may be more suitable than others.

Special relativity
In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time. In Albert Einstein's 1905 paper, 
"On the Electrodynamics of Moving Bodies", the theory is presented as being based on just two postulates:

The laws of physics are invariant (identical) in all inertial frames of reference (that is, frames of reference with no acceleration). This is known as the principle of relativity.

The speed of light in vacuum is the same for all observers, regardless of the motion of light source or observer. This is known as the principle of light constancy, or the principle of light speed invariance.

The first postulate was first formulated by Galileo Galilei (see Galilean invariance).
Giant (airship)
The Giant (Russian: Гигант) was a semi-rigid airship designed by engineers Alexander Kovanko and Athanasius Shabsky. It was the largest dirigible built in Russia. In subsequent years, no airships of this size were created. The largest airship built in Russia, the SSR W-6 (Osoaviakhim), had a volume of only 18 500 m3.

Semi-rigid airship
A semi-rigid airship is an airship which has a stiff keel or truss supporting the main envelope along its length. The keel may be partially flexible or articulated and may be located inside or outside the main envelope. The outer shape of the airship is maintained by gas pressure, as with the non-rigid "blimp". Semi-rigid dirigibles were built in significant quantity from the late 19th century but in the late 1930s they fell out of favour along with rigid airships. No more were constructed until the semi-rigid design was revived by the Zeppelin NT in 1997.

Semi-rigid construction is lighter-weight than the outer framework of a rigid airship, while it allows greater loading than a non-rigid type.

Space policy
Space policy is the political decision-making process for, and application of, public policy of a state (or association of states) regarding spaceflight and uses of outer space, both for civilian (scientific and commercial) and military purposes. International treaties, such as the 1967 Outer Space Treaty, attempt to maximize the peaceful uses of space and restrict the militarization of space.

Space policy intersects with science policy, since national space programs often perform or fund research in space science, and also with defense policy, for applications such as spy satellites and anti-satellite weapons.  It also encompasses government regulation of third-party activities such as commercial communications satellites and private spaceflight.

Space policy also encompasses the creation and application of space law, and space advocacy organizations exist to support the cause of space exploration.
Agonopterix propinquella
Agonopterix propinquella is a species of moth of the family Depressariidae. It is found in Europe.

The wingspan is 16–19 mm.Similar to Agonopterix subpropinquella. Adults are on wing from September to July depending on the location.

The larvae feed on Arctium, Carduus, Centaurea, Cirsium arvense, Cirsium vulgare, Cynara, Mycelis muralis and Serratula. They initially mine the leaves of their host plant. Larvae can be found from July to early August. They are apple green with a black head.

Arctium
Arctium is a genus of biennial plants commonly known as burdock, family Asteraceae. Native to Europe and Asia, several species have been widely introduced worldwide. Burdock's clinging properties, in addition to providing an excellent mechanism for seed dispersal, led to the invention of the hook-and-loop fastener.

Blount baronets of Tittenhanger (1680)
The Blount Baronetcy, of Tittenhanger in the County of Hertford, was created in the Baronetage of England on 27 January 1680 for Thomas Pope Blount (b. 1649). In the 16th century Elizabeth Blount, daughter of Sir Walter Blount of Blount Hall, Staffordshire (a descendant of the Sodington Blounts), married Sir Thomas Pope of Tittenhanger, Herefordshire. Her nephew Sir Thomas Pope Blount (d. 1638) inherited the estate at Tittenhanger on her death. The first Baronet was the grandson of Sir Thomas and son of the traveller Sir Henry Blount. He represented St Albans and Hertfordshire in the House of Commons. The title became extinct on the death of his grandson, the third Baronet, in 1757.

Gębice [ɡɛmˈbit͡sɛ] is a village in the administrative district of Gmina Gubin, within Krosno Odrzańskie County, Lubusz Voivodeship, in western Poland, close to the German border.

During World War II, in 1939, Nazi Germany established and operated a temporary prisoner-of-war camp for Poles in the village. Also Polish civilians and clergy were held in the camp, including Maximilian Kolbe, Franciscan friar and saint of the Catholic Church, later killed in the Auschwitz concentration camp. In October 1939, there were over 25,000 prisoners in the camp, which was infamous for its terrible conditions, and prisoners were subjected to tortures and starvation. There is a memorial to the victims.

Krosno County, Lubusz Voivodeship
Krosno County (Polish: powiat krośnieński) is a unit of territorial administration and local government (powiat) in Lubusz Voivodeship, western Poland, on the German border. It came into being on 1 January 1999 as a result of the Polish local government reforms passed in 1998. Its administrative seat is the town of Krosno Odrzańskie, which lies 30 km (19 mi) west of Zielona Góra and 79 km (49 mi) south of Gorzów Wielkopolski. The only other town is Gubin which is the biggest town in the county. It is situated on the German border 28 km (17 mi) west of Krosno Odrzańskie.

The county covers an area of 1,390 square kilometres (536.7 sq mi). As of 2019 its total population is 55,018, out of which the population of Gubin is 16,619, that of Krosno Odrzańskie is 11,319, and the rural population is 27,080.
Marasmianympha
Marasmianympha is a genus of moths of the grass moth family (Crambidae) described by Eugene G. Munroe in 1991. Its single species, Marasmianympha eupselias, was described by Edward Meyrick in 1929. Among the grass moths, it belongs to subfamily Spilomelinae. It is endemic to the Marquesas Islands of Polynesia, where it has been recorded on Fatu Hiva, Hiva Oa and Tahuata, but is suspected to occur on other islands as well. The holotype specimen is in the Natural History Museum, London.

When first described, this moth was assigned to the genus Aulacodes in subfamily Acentropinae (then known as Nymphulinae). But eventually it was determined that despite a superficial similarity, M. eupselias is not a member of the Acentropinae, and hence by grass moth standards not at all closely related to Aulacodes.

Hiva Oa
With its 320 square kilometres (124 square miles), Hiva Oa (Marquesan: Hivaʻoa) is the second largest island in the Marquesas Islands, in French Polynesia, an overseas territory of France in the Pacific Ocean. Located at 9 45' south latitude and 139 W longitude, it is the largest island of the southern Marquesas group. Around 2,200 people reside on the island. A volcano, Temetiu, is Hiva Oa's highest point reaching an elevation of 1,269 m (4,163 ft.)

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.
