user: Given a reference text about a snowball effect, tell me how it applies to aerospace engineering.

assistant: <think>
A snowball effect is a process that starts from an initial state of small significance and builds upon itself (an exacerbating feedback), becoming larger (graver, more serious), and also perhaps potentially dangerous or disastrous (a vicious circle), though it might be beneficial instead (a virtuous circle). This is a cliché in cartoons and modern theatrics, and it is also used in psychology.

The common analogy is with the rolling of a snowball down a snow-covered hillside. As it rolls the ball will pick up more snow, gaining more mass and surface area, and picking up even more snow and momentum as it rolls along.

In aerospace engineering, it is used to describe the multiplication effect in an original weight saving. A reduction in the weight of the fuselage will require less lift, meaning the wings can be smaller. Hence less thrust is required and therefore smaller engines, resulting in a greater weight saving than the original reduction. This iteration can be repeated several times, although the decrease in weight gives diminishing returns.

The startup process of a feedback electronic oscillator, when power to the circuit is switched on, is a technical application of the snowball effect. Electronic noise is amplified by the oscillator circuit and returned to its input filtered to contain primarily the selected (desired) frequency, gradually getting stronger in each cycle, until a steady-state oscillation is established, when the circuit parameters satisfy the Barkhausen stability criterion.</think>

user: What are Singapore's official languages?

assistant: <think>
Singapore (/ˈsɪŋ(ɡ)əpɔːr/ (listen)), officially the Republic of Singapore, is an island country and city-state in maritime Southeast Asia. It lies about one degree of latitude (137 kilometres or 85 miles) north of the equator, off the southern tip of the Malay Peninsula, bordering the Strait of Malacca to the west, the Singapore Strait to the south, the South China Sea to the east, and the Straits of Johor to the north. The country's territory is composed of one main island, 63 satellite islands and islets, and one outlying islet; the combined area of these has increased by 25% since the country's independence as a result of extensive land reclamation projects. It has the third highest population density in the world. With a multicultural population and recognising the need to respect cultural identities of the major ethnic groups within the nation, Singapore has four official languages: English, Malay, Mandarin, and Tamil. English is the lingua franca and numerous public services are available only in English. Multi-racialism is enshrined in the constitution and continues to shape national policies in education, housing, and politics.</think>

user: Extract why Tim Lincecum was called "The Freak"

assistant: <think>
Timothy Leroy Lincecum (/ˈlɪnsəkʌm/ LIN-sə-kum; born June 15, 1984), nicknamed "The Freak", "The Franchise", "The Freaky Franchise" and "Big Time Timmy Jim", is an American former professional baseball pitcher. He played in Major League Baseball (MLB) for the San Francisco Giants (2007 to 2015) and Los Angeles Angels (2016). A two-time Cy Young Award winner, Lincecum helped the Giants win three World Series championships from 2010 through 2014.</think>
Nicknamed "The Freak" for his ability to generate powerful pitches despite his slight physique (5 feet 11 inches, 170 pounds), the power pitcher led the National League in strikeouts for three consecutive years in a span from 2008 to 2010. He also led the league in shutouts in 2009 and won the Babe Ruth Award in 2010 as the most valuable player of the MLB postseason. Lincecum won consecutive Cy Young Awards in 2008 and 2009, becoming the first MLB pitcher to win the award in his first two full seasons. He also appeared in four consecutive All-Star Games from 2008 through 2011 and pitched no-hitters in 2013 and 2014.
