I was surprised to see the description given for "liberal arts education" in Wikipedia as follows:
Liberal arts today consists of four types of areas: the natural sciences, social sciences, arts, and humanities. Its central academic disciplines are physics, biology, philosophy, logic, linguistics, literature, history, political science, psychology, mathematics, and many others.

I'm obviously talking about the modern usage of "liberal arts", not the ancient or historical term (trivium and quadrivium). I had in mind something more akin to humanities, so excluding natural sciences like physics, chemistry, even astronomy. My conception seems to be right at least by some definitions of the term. The first result I get when I search for "liberal arts" is a definition by Oxford Dictionaries:
Arts subjects such as literature and history, as distinct from science and technology.
Oxford Dictionaries at lexico.com
It's defined by Collins as:
(Education) the fine arts, humanities, sociology, languages, and literature. Often shortened to: arts
Collins English Dictionary
It's possible that the British English definition and/or the meaning of the term outside North America or USA is different. Two of the most common online American dictionaries seem to emphasize "general knowledge" as opposed to professional knowledge:
2 : college or university studies (such as language, philosophy, literature, abstract science) intended to provide chiefly general knowledge and to develop general intellectual capacities (such as reason and judgment) as opposed to professional or vocational skills
1. Academic disciplines, including literature, history, languages, philosophy, mathematics, and general sciences, viewed in contrast to professional and technical disciplines.
American Heritage Dictionary
I'm not sure whether things like physics and chemistry fall within the American dictionary definitions above, but the Wikipedia article clearly says that the natural sciences and life sciences are part of the liberal arts, and gives examples of physics, chemistry, geology, biology and neuroscience.
Liberal arts education: Modern usage (Wikipedia article)
Notwithstanding that many American dictionaries don't mention the natural sciences by name, at least the one below does:
1. academic college courses providing general knowledge and comprising the arts, humanities, natural sciences, and social sciences.
Random House Kerneman Webster's College Dictionary
Does anyone know whether even in America there's consensus among academics and institutions that "liberal arts" include things like physics, chemistry, geology or neuroscience?
