Lotna

Lotna is a Polish war film released in 1959 and directed by Andrzej Wajda.

Overview

This highly symbolic movie is both the director's tribute to the long and glorious history of the Polish cavalry, as well as a more ambiguous portrait of the passing of an era. Wajda was the son of a Polish Cavalry officer who was murdered by the Soviets during the Katyn massacre.

The horse Lotna represents the entire Romantic tradition in culture, a tradition that had a huge influence in the course of Polish history and the formation of Polish literature. Lotna is Wajda's meditation on the historical breaking point that was 1939, as well as a reflection on the ending of an entire era for literature and culture in Poland and in Europe as a whole. Writing of the film, Wajda states that it "held great hopes for him, perhaps more than any other." Sadly, Wajda came to think of Lotna "a failure as a film."

The film remains highly controversial, as Wajda includes a mythical scene in which Polish horsemen suicidally charge a unit of German tanks, an event that never actually happened.

Ten Speed

Ten Speed may refer to:

Four-velocity

In physics, in particular in special relativity and general relativity, a four-velocity is a four-vector in four-dimensional spacetime that represents the relativistic counterpart of velocity, which is a three-dimensional vector in space.

Physical events correspond to mathematical points in time and space, the set of all of them together forming a mathematical model of physical four-dimensional spacetime. The history of an object traces a curve in spacetime, called its world line. If the object is massive, so that its speed is less than the speed of light, the world line may be parametrized by the proper time of the object. The four-velocity is the rate of change of four-position with respect to the proper time along the curve. The velocity, in contrast, is the rate of change of the position in (three-dimensional) space of the object, as seen by an observer, with respect to the observer's time.

The value of the magnitude of an object's four-velocity, i. e. the quantity obtained by applying the metric tensor g to the four-velocity u, that is ||u||² = u ⋅ u = g_μνu^νu^μ, is always equal to ±c², where c is the speed of light. Whether the plus or minus sign applies depends on the choice of metric signature. For an object at rest its four-velocity is parallel to the direction of the time coordinate with u⁰ = c. A four-velocity is thus the normalized future-directed timelike tangent vector to a world line, and is a contravariant vector. Though it is a vector, addition of two four-velocities does not yield a four-velocity: The space of four-velocities is not itself a vector space.

Car (surname)

Car is a surname. Notable people with the surname include:

Car (King of Caria)

Car of the Carians (Greek: Κάρ), according to Herodotus, was the brother of Lydus and Mysus. He was regarded as the eponymous and ancestral hero of the Carians who would have received their name from the king. He may or may not be the same as Car of Megara

The name "Car" is unrelated to the English word "car" (vehicle).

Car of the Carians

Herodotus mentions Car, brother of Lydus and Mysus; the three brothers were believed to have been the ancestral heroes and eponyms of the Carians, the Lydians and the Mysians respectively. This Car was credited by Pliny the Elder with inventing the auspicia.

Car was also said to have founded the city Alabanda, which he named after Alabandus, his son by Callirhoe (the daughter of the river god Maeander). In turn, Alabandus's name is said to have been chosen in commemoration of his Car's victory in a horse fight— according to the scholar Stephanus of Byzantium, "Alabandos" was the Carian word for "winner in a horse fight". Another son of Car, Idrieus, had the city Idrias named after himself.

Car (Greek mythology)

Car or Kar (Greek: Κάρ) is a name in Greek mythology that refers to two characters who may or may not be one and the same.

The name "Car" is unrelated to the English word "car" (vehicle).

Car of Megara

According to Pausanias, Car was the king of Megara and the son of Phoroneus (and Cerdo). His tomb was located on the road from Megara to Corinth. The acropolis at Megara derived its name Caria from him.

Car of the Carians

Herodotus mentions a (probably) different Car, brother of Lydus and Mysus; the three brothers were believed to have been the ancestral heroes and eponyms of the Carians, the Lydians and the Mysians respectively. This Car was credited by Pliny the Elder with inventing the auspicia.

Car was also said to have founded the city Alabanda, which he named after Alabandus, his son by Callirhoe (the daughter of the river god Maeander). In turn, Alabandus's name is said to have been chosen in commemoration of his Car's victory in a horse fight— according to the scholar Stephanus of Byzantium, "Alabandos" was the Carian word for "winner in a horse fight". Another son of Car, Idrieus, had the city Idrias named after himself.
