Solar system Quotes

“Consider now the primal scene of education in the modern elementary school. Let us assume that a teacher wishes to inform a class of some 20 pupils about the structure of atoms, and that she plans to base the day's instruction on an analogy with the solar system. She knows that the instruction will be effective only to the extent that all the students in the class already know about the solar system. A good teacher would probably try to find out. 'Now, class, how many of you know about the solar system?' Fifteen hands go up. Five stay down. What is a teacher to do in this typical circumstance in the contemporary American school?"If he or she pauses to explain the solar system, a class period is lost, and 15 of the 20 students are bored and deprived of knowledge for that day. If the teacher plunges ahead with atomic structure, the hapless five—they are most likely to be poor or minority students—are bored, humiliated and deprived, because they cannot comprehend the teacher's explanation.”

“The solar system is off center and consequently man is too ...”

“When you look at the stars and the galaxy, you feel that you are not just from any particular piece of land, but from the solar system.”

“It's time for the human race to enter the solar system.”

“Like the original concept, the stormrider had rectangular blades, sixteen of them radiating out from the hub, each one a flat lattice of struts twenty-five kilometers long, made from the toughest steelsilicon fibers the Commonwealth knew how to manufacture. Twenty-three kilometers of them were covered by an ultra-thin silvered foil, giving a total surface area of over one thousand eight hundred square kilometers for the solar wind to impact on. Even in an ordinary solar system environment that would have produced a considerable torque. In the Half Way system the stormrider was positioned at the Lagrange point between the red star and its neutron companion, right in the middle of the plasma current, where the ion density was orders of magnitude thicker than any normal solar wind. The power the stormrider produced when it was in the thick of the flow was enough to operate the wormhole generator. But it couldn’t simply sit at the Lagrange point producing electricity continuously; that would have been too much like perpetual motion. As the waves of plasma pushed against it, they exerted an unremitting pressure on the blades that blew the stormrider away from the Lagrange point out toward the neutron star. So for five hours the two sets of blades would turn in opposite directions, generating electricity for the Port Evergreen wormhole that was delivered via a zero-width wormhole. The stormrider also stored some of the power, so that at the end of the five hours when it was out of alignment, it had enough of a reserve to fire its onboard thrusters, moving itself even farther out of the main plasma stream where the pressure was reduced. From there it chased a simple fifteen-hour loop back around through open space to the Lagrange point, where the cycle would begin again.”

“Mars is the only place in the solar system where it's possible for life to become multi-planetarian.”

“Man must at all costs overcome the Earth's gravity and have, in reserve, the space at least of the Solar System.”

“We're in the space exploration business, and the outer solar system is a wild, wooly place. We haven't explored it very well.”

“When I was a little kid, we only knew about our nine planets. Since then, we've downgraded Pluto but have discovered that other solar systems and stars are common. So life is probably quite prevalent.”
