[Q]: Prior Zelda games have employed a theme of two separate, yet connected, worlds. In A Link to the Past, Link travels between a "Light World" and a "Dark World"; in Ocarina of Time, as well as in Oracle of Ages, Link travels between two different time periods. The Zelda team sought to reuse this motif in the series' latest installment. It was suggested that Link transform into a wolf, much like he metamorphoses into a rabbit in the Dark World of A Link to the Past.[m] The story of the game was created by Aonuma, and later underwent several changes by scenario writers Mitsuhiro Takano and Aya Kyogoku. Takano created the script for the story scenes, while Kyogoku and Takayuki Ikkaku handled the actual in-game script. Aonuma left his team working on the new idea while he directed The Minish Cap for the Game Boy Advance. When he returned, he found the Twilight Princess team struggling. Emphasis on the parallel worlds and the wolf transformation had made Link's character unbelievable. Aonuma also felt the gameplay lacked the caliber of innovation found in Phantom Hourglass, which was being developed with touch controls for the Nintendo DS. At the same time, the Wii was under development with the code name "Revolution". Miyamoto thought that the Revolution's pointing device, the Wii Remote, was well suited for aiming arrows in Zelda, and suggested that Aonuma consider using it.[n]
[A]: What does Link morph into in A Link to the Past?


[Q]: On July 11, 1877, a few days after the Bell Telephone Company was established, Bell married Mabel Hubbard (1857–1923) at the Hubbard estate in Cambridge, Massachusetts. His wedding present to his bride was to turn over 1,487 of his 1,497 shares in the newly formed Bell Telephone Company. Shortly thereafter, the newlyweds embarked on a year-long honeymoon in Europe. During that excursion, Bell took a handmade model of his telephone with him, making it a "working holiday". The courtship had begun years earlier; however, Bell waited until he was more financially secure before marrying. Although the telephone appeared to be an "instant" success, it was not initially a profitable venture and Bell's main sources of income were from lectures until after 1897. One unusual request exacted by his fiancée was that he use "Alec" rather than the family's earlier familiar name of "Aleck". From 1876, he would sign his name "Alec Bell". They had four children:
[A]: Who did Bell marry in 1877?


[Q]: A more accurate description of the hydrogen atom comes from a purely quantum mechanical treatment that uses the Schrödinger equation, Dirac equation or even the Feynman path integral formulation to calculate the probability density of the electron around the proton. The most complicated treatments allow for the small effects of special relativity and vacuum polarization. In the quantum mechanical treatment, the electron in a ground state hydrogen atom has no angular momentum at all—an illustration of how the "planetary orbit" conception of electron motion differs from reality.
[A]:
What kind of movement does the electron not have in ground state?
