This is a listing of characters from the Nickelodeon animated television series Hey Arnold! and Hey Arnold!: The Movie.
Arnold (voiced by Toran Caudell in season 1; Phillip Van Dyke in seasons 2–3; Spencer Klein in seasons 4–5; Alex D. Linz in season 5) is the nice, kind, optimistic nine-year-old protagonist and title character of the series. He is a dreamer and an idealist who always tries to see the best in people and do the right thing. Whenever he sees someone in trouble, especially Helga, Arnold goes out of his way to help them out, even if it is not sensible to do so. Arnold often acts as the stable center to those around him, whether he is around his "family" in his paternal grandparents' boarding house, or around his friends at school. He lives in Sunset Arms boarding house with his grandparents, Phil and Getrude.
Arnold has had two major crushes in the series: one with sixth-grader Ruth McDougal (through most of season 1), and one with a classmate named Lila Sawyer (introduced in season 2). However, his most catalytic relationship is with his classmate Helga Pataki. Helga is secretly in love with him, though to keep these feelings secret she bullies Arnold. Arnold is completely unaware of this fact for most of the series, other than the occasional hint from Helga and other classmates. Helga revealed her secret to Arnold during Hey Arnold!: The Movie, but Arnold gave Helga the opportunity to take back her confession, attributing it to "the heat of the moment". According to series creator Craig Bartlett, had the canceled "Jungle Movie" sequel been animated, Arnold would have returned Helga's feelings with a kiss of his own, with his best friend interrupting the moment. Arnold is friends with most of his fellow fourth-graders, with the best of which being Gerald Johanssen, whose friendship dates as far back as preschool.
Flight dynamics is the study of the performance, stability, and control of vehicles flying through the air or in outer space. It is concerned with how forces acting on the vehicle influence its speed and attitude with respect to time.
In fixed-wing aircraft, the changing orientation of the vehicle with respect to the local air flow is represented by two critical parameters, angle of attack ("alpha") and angle of sideslip ("beta"). These angles describe the vector direction of airspeed, important because it is the principal source of modulations in the aerodynamic forces and moments applied to the aircraft.
Spacecraft flight dynamics involve three forces: propulsive (rocket engine), gravitational, and lift and drag (when traveling through the earths or any other celestial atmosphere). Because aerodynamic forces involved with spacecraft flight are very small, this leaves gravity as the dominant force.
Aircraft and spacecraft share a critical interest in their orientation with respect to the earth horizon and heading, and this is represented by another set of angles, "yaw," "pitch" and "roll" which angles match their colloquial meaning, but also have formal definition as an Euler sequence. These angles are the product of the rotational equations of motion, where orientation responds to torque, just as the velocity of a vehicle responds to forces. For all flight vehicles, these two sets of dynamics, rotational and translational, operate simultaneously and in a coupled fashion to evolve the vehicle's state (orientation and velocity) trajectory.
List auf Sylt (known as List until 31 December 2008) is the northernmost municipality in Germany, located on the North Sea island of Sylt close to Denmark in the district of Nordfriesland in the state of Schleswig-Holstein.
List derived from the Middle Low German Liste (ledge, bar or edge).
List was originally a Danish settlement. It was first mentioned in 1292 (Lystum). The original village was destroyed by the great flood of 1364. The settlement was rebuilt further east from the previous location. In the mid-15th century, a church named St. Jürgen was mentioned. In a treaty of 1460, Schleswig and Holstein were linked to the Danish crown, but List remained part of the royal enclaves, small areas of the Kingdom of Denmark situated within the Duchy of Schleswig, but directly controlled by the Danish king.
From the 16th century, the people of List mostly made a living from Oyster farming, raising sheep and collecting and selling gull eggs. At the time, List was an important protective anchorage. In 1644, a Swedish-Dutch fleet of 26 ships commanded by Admiral Thijssen was attacked in the Lister Tief and defeated by Danish ships commanded by king Christian IV of Denmark. The anchorage north of today's town was named Königshafen to honour this event.
Hey or Hey! may refer to:
Hey! is an album by Julio Iglesias. It was released in 1980 by Columbia Records. The album hit number one worldwide, and sales of the Spanish version purportedly surpassed 20 million. In 1981, Iglesias was nominated for a Grammy Award for the album under the Latin Pop Album category.
Hey! is the debut studio album by Brazilian recording artist Jullie. It was released on September 22, 2009 by Deckdisc. After writing songs for several established acts, Jullie released this album. The main theme of the songs is girl power. The songs are mostly inspired by Jullie's love of youth, rebellion, and discover who you are in 4.modern lifestyle. Musically, the album drew inspiration from pop and pop rock influenced by singers like Lily Allen, Madonna, Alanis Morissette, and its main reference, Katy Perry, directed to a feminist position. The album was praised by the young, calling Jullie as "Brazilian Katy Perry" for his music style and way of dressing. The first single "Alice" was released in April and the second single "Hey!" was released in November, 2009.
Arnold is a lunar crater that is located in the north-northeastern part of the visible Moon, near the lunar limb. This location gives the crater a notably oval appearance due to foreshortening, although the formation is actually relatively round. It lies to the northeast of the Mare Frigoris, to the north of the crater Democritus. West of Arnold is the smaller crater Moigno.
The ancient rim of Arnold has been worn and rounded by ages of subsequent bombardment. There is a gap in the wall to the southwest, marked by the tiny crater Arnold J, and the wall is relatively low along the eastern edge. The northern half of the rim is the most intact, particularly to the northeast where is joins the satellite crater Arnold A.
The inner floor of Arnold crater has been resurfaced by lava, and is relatively flat except for a number of tiny craterlets. The most notable crater in the interior is Arnold F, in the northwest section. If the crater once possessed a central peak, no sign of this feature now remains.
