Glauber is a scientific discovery method, written in the context of computational philosophy of science it is related to machine learning in artificial intelligence.

Glauber was written by Pat Langley, Herbert A. Simon, G.Bradshaw and J.Zitkow with other programs in order to show how scientific discovery may be achieved by problem solving methods.

Their programs simulate historical scientific discoveries based on empirical evidence known at the time of discovery.

Glauber was named after Johann Rudolph Glauber, a 17th century alchemist whose work helped to develop acid-base theory. Glauber rediscovers the law of acid-alkali reactions producing salts, given the qualities of substances and observed facts, the result of mixing substances. From that knowledge Glauber discovers that substances that taste bitter reacts with substances tasting sour producing substances tasting salty. In few words the law:

Glauber was designed by Pat Langley as part of his work on discovery heuristics in an attempt to have a computer automatically review a host of values and characteristics and make independent analyses from them. In the case of Glauber, the goal was to have an autonomous application that could estimate or even perfectly describe the nature of a given chemical compound by comparing it to related substances. Langley formalized and compiled Glauber in 1983.

Glauber de Andrade Rocha (March 14, 1939 – August 22, 1981) was an influential Brazilian film director, actor and writer. He is best known for his movie Deus e o Diabo na Terra do Sol (aka Black God, White Devil) from 1964.

Rocha was born in Vitória da Conquista, Bahia, Brazil and moved with his family to Salvador when he was only 9 years old, there studying in a famous and respected Presbyterian school.

During his adolescence, he developed great interest in arts, especially theatre and cinema, and even joined a drama group. He was also very active in politics, a trait that would be strongly influential in his works. A member of the Brazilian radical left, he helped start a political party in the late 1980s that called for an anti-capitalist people's revolution and, among other things, advocated the abolition of money.

By the age of 16 he started freelancing for a local newspaper and debuted as a movie reviewer. Later, he attended Law School for about two years and in 1959, after taking part in some projects as assistant, he finally directed his first short, "Pátio". After gaining some recognition in Bahia for his critical and artistic work, Rocha decided to quit college and pursue a journalistic career, as well as being a film-maker.

Caetano Emanuel Viana Teles Veloso (Portuguese pronunciation: [kaeˈtɐ̃nu emanuˈɛw viˈɐ̃nɐ ˈtɛlis veˈlozu]; born August 7, 1942), better known as Caetano Veloso, is a Brazilian composer, singer, guitarist, writer, and political activist. Veloso first became known for his participation in the Brazilian musical movement Tropicalismo, which encompassed theatre, poetry and music in the 1960s, at the beginning of the Brazilian military dictatorship. He has remained a constant creative influence and best-selling performing artist and composer ever since.

Veloso was born in the city of Santo Amaro da Purificação, in Bahia, a state in the northeastern area of Brazil, but moved to Salvador, the state capital, as a college student in the mid-1960s. Soon after the move, Veloso won a music contest and was signed to his first label. He became one of the founders of Tropicalismo with a group of several other musicians and artists—including his sister Maria Bethânia—in the same period. However the Brazilian government at the time viewed Veloso's music and political action as threatening, and he was arrested, along with fellow musician Gilberto Gil, in 1969. The two eventually were exiled from Brazil, and went to London, where they lived for two years. After he moved back to his home country, in 1972, Veloso once again began recording and performing, becoming popular outside of Brazil in the 1980s and 1990s.
