The park has six themed areas. Unlike the other Walt Disney World parks, Disney's Hollywood Studios does not have a defined layout; it is more a mass of streets and buildings that blend into each other, much like a real movie studio would. The park used to have a large Hidden Mickey in the plaza at the end of Hollywood Boulevard which could be seen in aerial photographs of the park and on the park's early guide maps. However, construction and other changes to the park have gotten rid of much of this image.
Hollywood Boulevard is the park's main entrance and is lined with stores selling Disney merchandise. Parades such as the Pixar Block Party Bash travel down Hollywood Boulevard on their route through the park, and live street entertainment can be found here throughout the day. Michael Eisner, who had a major part in the park's creation ever since the earliest development, demanded the opening land operate on the same principle as Main Street, U.S.A. in Magic Kingdom, but in a style more fitting to the Studios.
At the far end of Hollywood Boulevard is the Sorcerer's Hat, the icon of Disney's Hollywood Studios. Behind it, inside a replica of Grauman's Chinese Theater, is The Great Movie Ride, a dark ride with scenes from several classic movies, including "Casablanca", "The Wizard of Oz" and "Raiders of the Lost Ark".
Echo Lake is the park's small oval-shaped lagoon, which was designed to form one of the ears in the big Hidden Mickey from the park's original layout. Around it are many attractions and services, some in buildings designed to look like the "California Crazy" form of architecture from Hollywood's Golden Age.
At The American Idol Experience, park guests can audition and sing for live audiences, and win a special front-of-the-line pass for the popular TV series' real tryouts. Next door, "Sounds Dangerous!" features a 3-D audio presentation starring comedian Drew Carey. In between them is the A.T.A.S. Hall of Fame Plaza, a display of busts of past and present icons of the television era, such as Oprah Winfrey and Walt Disney.
Echo Lake has three attractions based on characters and movies produced by George Lucas' Lucasfilm studio. "" is an upcoming motion simulator ride set in the "Star Wars" universe, and is a duplicate of the yet-to-be opened attraction at Disneyland. Jedi Training Academy, a live-action stage show, invites children to become "padawan learners" and receive "lightsaber training" from a Jedi master. Lastly, the live-action "Indiana Jones Epic Stunt Spectacular!" re-enacts various scenes from "Raiders of the Lost Ark" while illustrating how movie stunts are performed.
Originally the New York Street backlot set that was part of the park's original Backlot Studio Tour, the section was later opened to pedestrian traffic. Recently, some of it was changed to look like San Francisco and New York. The current version of the Studio Backlot Tour features the American Film Institute Showcase, a rotating exhibit of movie props and memorabilia, and a tram ride through the backlot areas and through "Catastrophe Canyon", an effects-laden "movie set." Kids can play on giant plants and toys at the Honey, I Shrunk the Kids Movie Set Adventure, based on the 1989 Disney movie. Added in 2005, the "Lights, Motors, Action! Extreme Stunt Show" is a behind-the-scenes look at how car action sequences are made for movies, and is based on a similar show at Walt Disney Studios Park.
This section of the park was originally the starting point for the tours of the park's active production studios. Its entrance is marked by a square "studio arch," much like a real Hollywood studio lot entrance might be marked. The Animation Courtyard is home to a number of attractions based on Disney characters of yesterday, today and tomorrow. The Magic of Disney Animation is an attraction that shows how to animate a character. It also has games and exhibits, along with meet-and-greet areas for Disney and Pixar characters.
Mickey Avenue, a section inside the Animation Courtyard, has two walk-through exhibits. is about the life and legacy of Walt Disney. It has photos, models, rare artifacts and a short biographical movie narrated by Julie Andrews. At "Journey into Narnia," guests can see props and set pieces from the "Chronicles of Narnia" movie series (originally distributed by Disney; now handled by 20th Century Fox), as well as meet Prince Caspian from "".
The Courtyard section also has two live shows. "Playhouse Disney Live on Stage!" has puppet characters from "Playhouse Disney" shows on The Disney Channel, including Mickey Mouse Clubhouse, Handy Manny, and Little Einsteins. Across the plaza, "Voyage of the Little Mermaid" uses glow-in-the-dark puppets, lasers, music, projectors, human actors and water effects to re-create favorite scenes and songs from the animated "Little Mermaid" movie.
The park's newest section has many of the original soundstages used when the park still made TV shows. Today, Toy Story Land looks like the Emeryville, California campus of Pixar Animation Studios with attractions including Toy Story Midway Mania!, an interactive 3D attraction based on classic carnival midway games, each hosted by characters from the "Toy Story" movie series. Toy Story Land is also the home of Luxo Jr., a six-foot-tall audio-animatronic version of Pixar's desk-lamp mascot. The moving character performs periodic shows throughout the day and evening across from Toy Story Midway Mania.
Sunset Boulevard was the first expansion to Disney's Hollywood Studios, opening in July 1994. The main attraction on Sunset Boulevard is The Twilight Zone Tower of Terror, a thrill ride based on the classic television series. Located nearby is Rock 'n' Roller Coaster Starring Aerosmith, an indoor roller coaster in the dark with three inversions that starts moving at a high speed.
Sunset Boulevard has two outdoor amphitheaters for live stage shows. The covered Theater of the Stars has "Beauty and the Beast Live on Stage", a stage show with scenes from the movie. The open-air Hollywood Hills Amphitheater is the home of "Fantasmic!", a nighttime show with Mickey Mouse and many other Disney characters in a story filled with fireworks, lasers and water effects.
Therocephalia
Therocephalia ('beast-heads') are an extinct group of theriodonts. They lived from the middle Permian into the Triassic 265—245 million years ago, about 20 million years.
The therocephalians are named after their large skulls. Their skulls, with the structure of their teeth, suggest that they were successful carnivores.
Like other non-mammalian therapsids, therocephalians are sometimes described as mammal-like reptiles. In fact Therocephalia is the group most closely related to the cynodonts, which gave rise to the mammals.
This relationship shows in a variety of anatomical features, possibly including whiskers and hair. There remain many unanswered questions about the phylogeny, anatomy, and physiology of therocephalians.
The fossils of therocephalians are numerous in the Karoo of South Africa, but have also been found in Russia, China, and Antarctica.
Early therocephalian fossils discovered in Middle Permian deposits of South Africa support a Gondwanan origin for the group, which seems to have spread quickly throughout the world. Although almost every therocephalian lineage ended during the great Permian–Triassic extinction event, a few representatives of the subgroup (called Eutherocephalia) survived into the early Triassic and continued to diversify.
However, the last therocephalians became extinct by the early middle Triassic. The reasons for their extinction are not known.
Matrix mechanics
Matrix mechanics is the first way that physicists found to express quantum physics in mathematical form. Werner Heisenberg initially developed this form of expression of the laws of physics just as an equation that he could use to predict the intensities of the photons in the various bands of the hydrogen spectrum.<br>
