Three-Quarters Quotes (3 quotes)

As Arthur C. Clarke has observed: “How inappropriate to call this planet Earth, when clearly it is Ocean.” Nearly three-quarters of the Earth’s surface is sea, which is why those magnificent photographs taken from space show our planet as a sapphire blue globe, flecked with soft wisps of cloud and capped by brilliant white fields of polar ice.
From opening paragraph to Chap. 6, 'The Sea', in James E. Lovelock, Gaia: A New Look at Life on Earth (1979) 84. The origin of the Arthur C. Clarke quote is not cited therein, and Webmaster has, as yet, been unable to locate a primary source, although found widely quoted without citation, in print and on the web. Note that G. Carleton Ray made a similar quote in 1963, naming “sea” rather than “Ocean”. See the web page for Ray on this site for his quote, beginning, “We call this planet Earth…”.

It is important to realize that life on this planet has spent about three-quarters of its existence in single-celled form, and even today the majority of organisms still exist as single cells. The evolutionary pressure to become complex is evidently not very great.

The view of the moon that we’ve been having recently is really spectacular. It fills about three-quarters of the hatch window, and of course we can see the entire circumference even though part of it is in complete shadow and part of it is in earthshine. It’s a view worth the price of the trip.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
