Who wrote the following : a) Revolutions of the Heavenly Bodies b) The Advancement of Learning [MEG 101 Prerestoration]

a) "Revolutions of the Heavenly Bodies" was written by Nicolaus Copernicus, a Polish astronomer and mathematician, and published in 1543. It presented the idea of a heliocentric model of the solar system, with the Sun at the center and the planets orbiting around it. This was a major departure from the previously accepted geocentric model, which placed the Earth at the center.

b) "The Advancement of Learning" was written by Francis Bacon, an English philosopher and statesman, and published in 1605. It was an influential work in the fields of philosophy and science, and argued for the importance of empirical observation and experimentation in the pursuit of knowledge. Bacon is often regarded as one of the founders of the scientific method, which is based on empirical observation and the testing of hypotheses through experimentation.
