When the British mathematician G. H. Hardy received a letter in 1913 from an unknown mathematics enthusiast in India, he found the attached theorems and identities to be so brilliant and insightful that he suspected the man to be a fraud. Some of the results were so unusual and exotic that Hardy believed they had to be correct, because no-one could be creative enough to fabricate them. One colleague noted that every theorem contained in the letter was far too advanced to be given in any mathematical examination. The author of the letter was an Indian mathematician named Srinivasa Ramanujan.

The first manned space flight in human history to leave Earth orbit was Apollo 8. American astronauts Frank Borman, Jim Lovell and Bill Anders orbited the moon ten times on Christmas Eve of 1968 before returning to Earth three days later. The three were the first humans to see the Earth as a whole planet, the first humans to see the far side of the moon directly, and the first humans to witness an event called “earthrise.”

The most well-known example of a curve of constant width is a circle, but many other constructions are known. Any triangle can also be used to construct such a curve, and the simplest example of this is the Reuleaux triangle, often used in machinery to convert rotational motion to reciprocating motion.

Classical Riemann integration fails to be well-defined when one considers the integral of pathological functions or limit of sequences of functions. It also has limited scope in terms of functions it can be used to integrate. Many of these problems are rectified by using Lebesgue integration.

The yonkoma manga series Azumanga Daioh began as a serialized comic in the magazine Dengeki Daioh, from which the manga gets the second half of its name. The plot focuses primarily on the lives of six high-school girls and two of their teachers. J.C.Staff created an anime based off the series in 2002.

Spirit Airlines changed its business model in 2007 to become an ultra low-cost carrier and has since become one of the largest low-cost carriers in the United States. The company’s business model is based on itemizing the cost of services such as checked bags and seat upgrades, so that commuting passengers can avoid paying for unused services. The airline has received much criticism by travelers as well as the US government.

The first space launch facility in the world was built by the USSR at Baikonur in Kazakhstan. Christened the “Cosmodrome,” the facility is still operational as of November 2016 and has been the launch site of every manned space flight by the Soviet Union or the Russian Federation. The land on which the facility was built is leased by Kazakhstan to the Russian government, and the facility is both privately and publicly operated.

A fire at a warehouse in the Port of Tianjin on 12 August 2015 caused a container of nitrocellulose to overheat and explode. The heat from the blast caused another container to ignite, which was filled with several hundred tons of ammonium nitrate. The resulting detonation was large enough to be recorded on seismographs in the surrounding area as equivalent to a 2.9 magnitude earthquake.

Overdrive is a mechanical principle in which a vehicle moving at a constant speed will change the gear ratios used in its transmission to make the engine output its maximum power relative to the vehicle’s speed. This causes the engine to rotate at fewer revolutions per minute, reducing fuel consumption. The principle also helps to reduce the need to downshift when the vehicle reduces speed.

When a mobile phone connects to a wireless network via the GSM protocol, the network is not required to authenticate itself to the handset. This allows for a type of man-in-the-middle attack in which a malicious party can falsely report itself as a GSM tower to the handset and intercept its outgoing signal. This type of attack is know as an ISMI-catcher.

If a conic can be factored over an algebraically-closed field, that conic is said to be degenerate. Geometrically, a degenerate conic is formed when a plane intersects the vertex of a double cone. In the real plane, a degenerate conic may manifest itself as one straight line, two lines, a single point, or the null set.

When the game was released in North America, Jet Set Radio was renamed to Jet Grind Radio because of local trademark issues. The game was modified slightly in order to appeal more to American gamers, and unlike its Japanese counterpart, it included the ability to access SegaNet. Two new levels were also inclulded in the North American release; these were later included in a Japanese rerelease titled De La Jet Set Radio.
