Ryerson Astronomical Society (RAS) in 1950s

As a science major student, I always learned about history of science, specifically physics and astrophysics. For example, Galileo created the first telescope, or Newton invented Newton's three laws of motion, then Einstein found Relativity that contradicted with almost everything Newton said. "Why do we have to learn Newton's three laws then?" I often asked myself why they have to teach about the history of science since it will never help me solve Schrödinger equation equations or any physics equations.

It is not until I learned that these discoveries did not happen far away from where my classes are that I realized how amazing it felt to be a part of the big community of science. Milikan's oil drop experiment occurred in the basement of where I took my first-year Calculus, or Enrico Fermi engineered the first controlled, self-sustaining nuclear chain reaction happened at the library where I often cramped my final exam studies until the last minute. 
Prof. Vandervoort gave a talk on the history of RAS on 1/27/2014

Pale Blue Dot: A Vision of the Human Future in Space - Carl Saga

The Pale Blue Dot is a photograph of planet Earth taken in 1990 by the Voyager 1 spaceprobe from a record distance of about 6 billion kilometers (3.7 billion miles) from Earth.
From this distant vantage point, the Earth might not seem of any particular interest. But for us, it's different. Consider again that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.
