Oz Bach

Paul Michael "Oz" Bach (June 24, 1939 – September 21, 1998) was an American folk musician and guitarist for the 1960s group Spanky and Our Gang.

Bach entered music in 1962 as a guitarist, singer and comedian, before switching to bass in 1963. He then played as a back-up musician for Fred Neil, Tom Paxton, Bob Gibson and Josh White. In 1965, Bach and his friend Nigel Pickering made the acquaintance of Elaine "Spanky" McFarlane, a singer from Chicago. The three later became Spanky and Our Gang. The trio released their eponymous debut album in 1967.

He left the band prior to the release of their second album Like to Get to Know You in 1968. He then began to work as an arranger for Linda Ronstadt, Steve Miller and Sérgio Mendes. In the late sixties, Bach joined band such as Wings, Spooner Summit, and Tarantula.

After 1972, Bach started a talk show in Florida and directed an award-winning short film "Froggy Went A-Courtin'" (1977).

Bach died of cancer in September 1998. He was buried at the Blue Ridge Gardens of Memory Cemetery at Pisgah Forest, North Carolina. He was married four times and had seven children: Philip, Kelly, Kim, Jessica, Sarah, Belinda and Jonathan.

Surname

A surname or family name is a name added to a given name. In many cases, a surname is a family name and many dictionaries define "surname" as a synonym of "family name". In the western hemisphere, it is commonly synonymous with last name because it is usually placed at the end of a person's given name.

In most Spanish-speaking and Portuguese-speaking countries, two or more last names (or surnames) may be used. In China, Hungary, Japan, Korea, Madagascar, Taiwan, Vietnam, and parts of India, the family name is placed before a person's given name.

The style of having both a family name (surname) and a given name (forename) is far from universal. In many countries, it is common for ordinary people to have only one name or mononym.

The concept of a "surname" is a relatively recent historical development, evolving from a medieval naming practice called a "byname". Based on an individual's occupation or area of residence, a byname would be used in situations where more than one person had the same name.

Context-sensitive language

In theoretical computer science, a context-sensitive language is a formal language that can be defined by a context-sensitive grammar (and equivalently by a noncontracting grammar). That is one of the four types of grammars in the Chomsky hierarchy.

Computational properties

Computationally, a context-sensitive language is equivalent with a linear bounded nondeterministic Turing machine, also called a linear bounded automaton. That is a non-deterministic Turing machine with a tape of only kn cells, where n is the size of the input and k is a constant associated with the machine. This means that every formal language that can be decided by such a machine is a context-sensitive language, and every context-sensitive language can be decided by such a machine.

This set of languages is also known as NLINSPACE or NSPACE(O(n)), because they can be accepted using linear space on a non-deterministic Turing machine. The class LINSPACE (or DSPACE(O(n))) is defined the same, except using a deterministic Turing machine. Clearly LINSPACE is a subset of NLINSPACE, but it is not known whether LINSPACE=NLINSPACE.

Bach (journal)

Bach is a biannual peer-reviewed academic journal published by the Riemenschneider Bach Institute (Baldwin Wallace University). It covers the study of Johann Sebastian Bach and Baroque music. The journal was established in 1970 and the editor-in-chief is Melvin Unger (Baldwin Wallace University).
