Galileo Galilei

Disciplines:
philosophy of science/scientific method
mathematics
physics
astronomy

Summary

Italian physicist and astronomer who confirmed the Copernican heliocentric model with his telescope, developed the mathematical method of natural science, and was tried by the Inquisition — making him the founding martyr of scientific freedom and the symbol of the conflict between empirical inquiry and religious authority.

Core Contribution

Created the mathematical-experimental method of modern physics — 'the book of nature is written in the language of mathematics' — and demonstrated that falling bodies and projectile motion follow mathematical laws, establishing physics as a discipline rather than a branch of philosophy.
