The size and age of the Cosmos are beyond ordinary human understanding. Lost somewhere between immensity and eternity is our tiny planetary home. In a cosmic perspective, most human concerns seem insignificant, even petty. And yet our species is young and curious and brave and shows much promise. In the last few millennia we have made the most astonishing and unexpected discoveries about the Cosmos and our place within it, explorations that are exhilarating to consider. They remind us that humans have evolved to wonder, that understanding is a joy, that knowledge is prerequisite to survival. I believe our future depends on how well we know this Cosmos in which we float like a mote of dust in the morning sky.
Carl Sagan in Cosmos

Love this new project from Brain Pickings!
Prior to his untimely 1996 passing, Carl Sagan recorded a message for the brave men and women embarking on the first non-robotic mission to Mars. Here is an excerpt from that message (image source is unknown).
The Backbone of Night: Carl Sagan on cosmology throughout history
Some men just want to watch the world learn.
Famous Physicists as Children
From left to right:
Stephen Hawking (b. 1942) - Most well known for Hawking radiation and theorems involving gravitational singularities. He suffers from ALS, also known as Lou Gehrig’s disease - and is one of the most well known scientists of our time.
Neil deGrasse Tyson (b. 1958) - Currently the director of the Hayden Planetarium at the Rose Center for Earth and Space, Tyson is one of the leading science advocates in the world - and was one of the men who supported the demotion of Pluto.
Carl Sagan (1934-1996) - One of the most successful science popularizers of all time, Sagan was also the bestselling author of Cosmos, one of the most popular science books of all time. He was the first to propose that Jupiter’s moons Titan and Europa may hold liquid components of water on them.
Albert Einstein (1879-1955) - The most well known genius in history, Albert Einstein was a boss. During his career, he revolutionized almost every area of Physics, including quantum mechanics and he effectively founded the study of Cosmology. His theory of general relativity has been wildly successful, despite ‘attacks’ by neutrinos.
Richard Feynman (1918-1988) - His most important contributions came via his path integral formulation of quantum mechanics and development of Quantum Electrodynamics (QED). Plus, he was a total badass.
