" "Many harebrained interpretations were also widely available, especially in weekly newspapers.
Carl Edward Sagan (9 November 1934 – 20 December 1996) was an American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, author, and science communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the hypothesis, accepted since, that the high surface temperatures of Venus can be attributed to, and calculated using, the greenhouse effect. He testified to the US Congress in 1985 that the greenhouse effect will change the earth's climate system.

Pliny suggested that the ostrich, then newly discovered, was the result of a cross between a giraffe and a gnat. (It would, I suppose, have to be a female giraffe and a male gnat.) In practice there must be many such crosses which have not been
attempted because of a certain understandable lack of motivation.
At the heart of science is an essential balance between two seemingly contradictory attitudes — an openness to new ideas, no matter how bizarre or counterintuitive they may be, and the most ruthless skeptical scrutiny of all ideas, old and new. This is how deep truths are winnowed from deep nonsense.
We’ve arranged a society on science and technology in which
nobody understands anything about science and technology, and
this combustible mixture of ignorance and power sooner or later is
going to blow up in our faces. I mean, who is running the science and
technology in a democracy if the people don’t know anything about
it? Science is more than a body of knowledge, it’s a way of thinking. If
we are not able to ask skeptical questions to interrogate those who tell
us something is true, to be skeptical of those in authority, then we’re
up for grabs for the next charlatan political or religious leader who
comes ambling along. It’s a thing that Jefferson lay great stress on.
It wasn’t enough, he said, to enshrine some rights in the Constitution
and the Bill of Rights, the people had to be educated and they have to
practice their skepticism and their education. Otherwise, we don’t run
the government, the government runs us. — Carl Sagan
