The telescope was not the instrument through which Galileo opened the skies four centuries ago, forever changing our concepts of worlds terrestrial and celestial. No, Galileo's breakthrough was not a technological one, nor an intellectual one per se. Copernicus and Kepler had laid out the concepts before Galileo pointed his modest tube into the sky. What made all the difference, the lever that finally displaced the constraining, earth-centered Ptolemaic cosmos and ushered in a heliocentric worldview and the many advances that came in the wake of empirical science, was nothing so concrete as lenses nor so abstract as mathematical formulas. No, it was Galileo's strategy for freely and publicly communicating his findings. Galileo opened the heavens with Open Access.

But academia is based not on the idea of increasing intellectual liquidity; it is based on impeding it. Think about it. Traditional teaching and learning, publishing, and credentialing all require
submitting to various academic structures (classes and classrooms, the
editorial review process, program requirements). Those
structures slow the flow of knowledge by artificially restricting it to traditional times and places (a semester or class period, a classroom or a campus) or by subjecting publications or individuals to editorial evaluation or institutional oversight (peer and tenure review). What is the result? Those students, scholars and their ideas are actually kept out of circulation while the slow wheels of evaluation (grading, editorial review) decide when and how ideas or people will get certain privileges or credentials.
