Relativity may refer to:
Relativity was a Scots-Irish quartet formed in 1985 consisting of two Scottish brothers and an Irish brother and sister. The four members of the band were brothers Johnny Cunningham (fiddle) and Phil Cunningham (accordion, keyboard, whistle, bodhran), and Irish sister and brother Tríona Ní Dhomhnaill (vocals, clavinet) and Mícheál Ó Domhnaill (vocals, guitar, keyboard). Each of the members enjoyed a flourishing solo career at the time Relativity was formed.
Relativity is a lithograph print by the Dutch artist M. C. Escher, first printed in December 1953.
It depicts a world in which the normal laws of gravity do not apply. The architectural structure seems to be the centre of an idyllic community, with most of its inhabitants casually going about their ordinary business, such as dining. There are windows and doorways leading to park-like outdoor settings. All of the figures are dressed in identical attire and have featureless bulb-shaped heads. Identical characters such as these can be found in many other Escher works.
In the world of Relativity, there are three sources of gravity, each being orthogonal to the two others. Each inhabitant lives in one of the gravity wells, where normal physical laws apply. There are sixteen characters, spread between each gravity source, six in one and five each in the other two. The apparent confusion of the lithograph print comes from the fact that the three gravity sources are depicted in the same space.
