Mazur–Ulam theorem
In mathematics, the Mazur–Ulam theorem states that if  and  are normed spaces over R and the mapping

is a surjective isometry, then  is affine.  It was proved by Stanisław Mazur and Stanisław Ulam in response to a question raised by Stefan Banach.

For strictly convex spaces the result is true, and easy, even for isometries which are not necessarily surjective. In this case, for any  and   in , and for any  in , write 

and denote the closed ball of radius R around v by .  Then  is the unique element of , so, since  is injective,  is the unique element of

and therefore is equal to . Therefore  is an affine map.  This argument fails in the general case, because in a normed space which is not strictly convex two tangent balls may meet in some flat convex region of their boundary, not just a single point.

Isometry
In mathematics, an isometry (or congruence, or congruent transformation) is a distance-preserving transformation between metric spaces, usually assumed to be bijective. The word isometry is derived from the Ancient Greek: ἴσος isos meaning "equal", and μέτρον metron meaning "measure". If the transformation is from a metric space to itself, it is a kind of geometric transformation known as a motion.

Any profits earned by a mutual insurance company are either retained within the company or rebated to policyholders in the form of dividend distributions or reduced future premiums.

Boys Don't Cry (The Cure album)
Boys Don't Cry is the Cure's first compilation album. Released in February 1980, this album is composed of several tracks from the band's May 1979 debut album Three Imaginary Boys (which had yet to see a US release) with material from the band's 1978–1979 era.

Behind the scenes of these albums, Bill Smith was the mastermind behind the concepts for both covers, while Chris Parry assumed the role of producer for both projects. Additionally, Tim Pope played a crucial role in directing the music videos for "Killing an Arab" and "Jumping Someone Else's Train", which were later featured in the 1986 video compilation. These behind-the-scenes efforts contributed significantly to the albums' artistic vision.

Killing an Arab
"Killing an Arab" is the debut single by English rock band the Cure. It was recorded at the same time as their first album Three Imaginary Boys (1979), but not included on the album. However, it was included on the band's first US album, Boys Don't Cry (1980).

The song's title and lyrics reference Albert Camus's 1942 novella The Stranger. Because of the title, the song has drawn controversy for what critics have described as promoting violence against Arabs, which songwriter Robert Smith pinned on the public's lack of knowledge regarding the novel. Shortly after its release, Smith said, "It just happened that the main character in the book had actually killed an Arab, but it could have been a Scandinavian or an English bloke." In 2003, Smith acknowledged that, "If I knew it before, I would have called it 'Standing on the Beach'. It would have avoided many troubles."

Northern Thailand, or more specifically Lan Na, is a region of Thailand. It is geographically characterized by several mountain ranges, which continue from the Shan Hills in neighboring Myanmar to Laos, and the river valleys that cut through them. Like most of Thailand, it has a tropical savanna climate, but its relatively high elevation and latitude contribute to more pronounced seasonal temperature variation, with cooler winters than the other regions.

Historically, northern Thailand has been linked to the Hariphunchai Kingdom, which emerged as a powerful state in the region in the 7th century. This kingdom was related to the Dvaravati that existed from the 6th to 11th centuries. The Hariphunchai culture later influenced the development of the Lanna Kingdom, which emerged in the 13th century and lasted until the 18th century.
