If a man loses pace with his companions, perhaps it is because he hears a different drummer. Let him step to the music which he hears, however measured, or far away.

Henry David Thoreau never said anything in thirteen words that could be said in eighty.

Three Possible Futures for the Universe via Chandra X-ray Observatory (Credit: NASA/CXC/M.Weiss)“This illustration shows three possible futures for the Universe, depending on the behavior of dark energy, by showing how the scale of the Universe may change with time. If dark energy is constant, as the new Chandra results suggest, the expansion should continue accelerating forever. If dark energy increases, the acceleration may happen so quickly that galaxies, stars, and eventually atoms will be torn apart, in the so-called Big Rip. Dark energy may also lead to a recollapse of the Universe, in the Big Crunch. The illustration also shows the early decelerating expansion of the Universe, followed by the accelerating phase that started about 6 billion years ago.”

It’s hard for me to see a more profound cosmic connection than the astonishing findings of modern nuclear astrophysics: except for hydrogen, all the atoms that make each of us up - the iron in our blood, the calcium in our bones, the carbon in our brains - were manufactured in red giant stars thousands of light years away in space and billions of years ago in time. We are, as I like to say, starstuff.

From Sophie’s World by Jostein Gaarder. Interesting material for me since I wish to introduce my future students to philosophy; Sophie is 14 years old.

At school she had trouble concentrating on what the teachers said. They seemed to talk only about unimportant things. Why couldn’t they talk about what a human being is — or about what the world is and how it came into being?
