There were still, in 1968, a few people who were afraid of the nuclear power plant. This means, simply, that operators in nuclear power plants need not be eminent physicists or mathematicians. They had some nuclear power, introduced a century or so ago by traders from Marduk, one of the really civilized planets.

A lunar eclipse and a solar eclipse refer to events involving three celestial bodies: the Sun (solar), the moon (lunar), and the Earth. A lunar eclipse occurs when the Earth passes between the Moon and the Sun, and the Earth's shadow obscures the moon or a portion of it. A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking all or a portion of the Sun. An eclipse can be total, partial, or annular. A total solar eclipse is when the moon blocks out the Sun entirely, a partial eclipse is when it blocks out a portion of the Sun, and an annular eclipse is when the moon is at its furthest point in orbit.
