The Parameters of "Spaceship Earth"

Our little Spaceship Earth is only eight thousand miles in diameter, which is almost a negligible dimension in the great vastness of space. Our nearest star — our energy-supplying mother-ship, the Sun — is ninety-two million miles away, and the nearest star is one hundred thousand times further away. It takes approximately four and one third years for light to get to us from the next nearest energy supply ship star. That is the kind of space-distanced pattern we are flying. Our little Spa...

 1847 Speculation About Extraterrestrials

In general I would be cautious against … plays of fancy and would not make way for their reception into scientific astronomy, which must have quite a different character. Laplace's cosmogenic hypotheses belong in that class. Indeed, I do not deny that I sometimes amuse myself in a similar manner, only I would never publish the stuff. My thoughts about the inhabitants of celestial bodies, for example, belong in that category. For my part, I am (contrary to the usual opinion) convinced ... th...

 The Energy Game in a Dead Moth

The moth moves across the porch, millimeter by millimeter, a brief stage of a longer journey of energy from the core of the sun to the table of the ants. Protons fuse at the center of the sun, releasing energy. The energy diffuses upward, taking several million years to reach the sun's surface, where it is released as heat and light. The light streaks across ninety-three million miles of space, reaching the Earth eight minutes later, where it falls upon the green leaves of plants. The plants ...

 The Beauty of Science

The world looks so different after learning science. For example, the trees are made of air, primarily. When they are burned, they go back to air, and in the flaming heat is relased the flaming heat of the sun which was bound in to convert the air into trees, and in the ash is the small remnant of the part which did not come from air, that came from the solid earth instead.

 Richard Feynman on Science

The World looks so different after learning science. For example, trees are made of air, primarily. When they are burned, they go back to air, and in the flaming heat is released the flaming heat of the sun which was bound in to convert the air into tree. [A]nd in the ash is the small remnant part which did not come from air, that came from the solid earth, instead. These are beautiful things, and the content of science is wonderfully full of them. They are very inspiring, and they can be us...
