Q: Question: How many Nobel Prizes in Physics were awarded before it was given to Leo Esaki? Passage 1:The game was first announced in July 2015, as a collaboration between Spike Chunsoft and tri-Ace in a fourteen-page article in Weekly Famitsu. The game will be developed by much of the same tri-Ace staff that had worked on the first Valkyrie Profile game, with assistance from Spike Chunsoft staff as well. Other key staff for the game include character designer Mino Taro of Konamis Love Plus series, and music composer Motoi Sakuraba, composer for tri-Ace's Valkyrie Profile and Star Ocean series. A trailer for the game was shown at the Tokyo Game Show in September 2015. Trailers for each of the game's characters were released over time through Famitsus YouTube channel. The game was first announced to be released on November 26, 2015, before being delayed to its final release date, December 17, 2015. Shortly after the game's Japanese release, Spike Chunsoft announced that there would be downloadable content collaborations some of tri-Ace's other games, including Valkyrie Profile and Star Ocean 5 games. The collaborations, released in March 2016, consisted of character costumes based on character's from the two aforementioned titles, along with a costume to dress up as Monokuma, the primary antagonist from Spike Chunsoft's Danganronpa series of video games.
 Passage 2:A tunnel diode or Esaki diode is a type of semiconductor diode that has negative resistance due to the quantum mechanical effect called tunneling. It was invented in August 1957 by Leo Esaki, Yuriko Kurose, and Takashi Suzuki when they were working at Tokyo Tsushin Kogyo, now known as Sony. In 1973, Esaki received the Nobel Prize in Physics, jointly with Brian Josephson, for discovering the electron tunneling effect used in these diodes. Robert Noyce independently devised the idea of a tunnel diode while working for William Shockley, but was discouraged from pursuing it. Tunnel diodes were first manufactured by Sony in 1957, followed by General Electric and other companies from about 1960, and are still made in low volume today.
 Passage 3:Soon after graduating college, Freedley met Alexander A. Aarons with whom he formed a long term producing partnership. Their first major hit was Lady Be Good! (1924) with music and lyrics by George and Ira Gershwin and featuring Fred Astaire and Adele Astaire. Over the next ten years the pair produced some of the most important works in the Broadway musical canon, featuring some of the most famous songs ever to emerge from the tin pan alley era, part of what is commonly referred to as "The Great American Songbook." The shows that followed included Tip-Toes (1925), Oh, Kay! (1926), and Funny Face (1927), again starring the Astaires. All the scores were written by the Gershwins. In 1928 Aarons and Freedley produced Here's Howe, featuring the music of Gus Kahn, Joseph Meyer, and Irving Caesar; Hold Everything!, with a score by Buddy DeSylva and Lew Brown; and Treasure Girl, with music by the Gershwins. In 1929 followed Spring Is Here and Heads Up!, both with songs by Richard Rodgers and Lorenz Hart. Another Gershwin hit was Girl Crazy (1930). The partnership ended in 1932. Freedley produced 30 shows total on Broadway.
