Science is a way to not fool ourselves.
Carl SaganRead
By looking far out into space we are also looking far back into time, back toward the horizon of the universe, back toward the epoch of the Big Bang.
Interpretation
Exploring space helps us understand the history of the universe and our place within it.
In this quote, Carl Sagan highlights the profound relationship between space and time. By observing distant celestial objects, we are not only witnessing their current state but also looking back in time to the very origins of the universe, such as the Big Bang. This perspective emphasizes the interconnectedness of time, space, and our understanding of cosmic events.

In a lecture about astrophysics, to explain the relationship between the universe and time.
Science is a way to not fool ourselves.
In more than one respect, the exploring of the Solar System and homesteading other worlds constitutes the beginning, much more than the end, of history.
How smart does a chimpanzee have to be before killing him constitutes murder?
The hole in the ozone layer is a kind of skywriting. At first it seemed to spell out our continuing complacency before a witch's brew of deadly perils. But perhaps it really tells of a newfound talent to work together to protect the global environment.
There is a reward structure in science that is very interesting: Our highest honors go to those who disprove the findings of the most revered among us. So Einstein is revered not just because he made so many fundamental contributions to science, but because he found an imperfection in the fundamental contribution of Isaac Newton.
The simplest thought, like the concept of the number one, has an elaborate logical underpinning.
At their best, at their most creative, science and engineering are attributes of liberty-noble expressions of man's God-given right to investigate and explore the universe without fear of social or political or religious reprisals.
We've all been sick; we're all afraid of infection. I think the easiest application to help people understand what quorum sensing is and why it's important to study is to tell them that if we could make the bacteria either deaf or mute, we could create new antibiotics.
As life forms, viruses are just inherently interesting. It's the microworld - this universe of life too small for us to see - but it's profoundly complicated, and immensely powerful. Ebola is like a beautiful and frightening predator. There is a wonder in the operations of nature that can't be denied, even when we're the losers.
This afternoon, I've arranged for this ceremony to be illuminated by solar power.
In science there is only physics; all the rest is stamp collecting.
The works of Lavoisier and his associates operated upon many of us at that time like the Sun's rising after a night of moonshine: but Chemistry is now betrothed to the Mathematics, and is in consequence grown somewhat shy of her former admirers.
