Education is the process of learning knowledge, information and skills during the course of life. Teachers may draw on many subjects, including reading, writing, mathematics, science and history. Teachers in specialized professions such as astrophysics, law, or zoology may teach only a certain subject, usually as professors at institutions of higher learning. There is also instruction in fields for those who want specific skills, such as those required to be a pilot. In addition there is education available at the informal level, e.g., at museums and libraries, with the Internet, and in life experience.
The right to education has been described as a basic human right: since 1952, Article 2 of the first Protocol to the European Convention on Human Rights obliges all signatory parties to guarantee the right to education. At world level, the United Nations' International Covenant on Economic, Social and Cultural Rights of 1966 guarantees this right under its Article 13.
