Intuition is given only to him who has undergone long preparation to receive it.
Quote by -Louis Pasteur
Change only favours minds that are diligently looking and preparing for discovery.
Quote by -Louis Pasteur
If it is a terrifying thought that life is at the mercy of the multiplication of these minute bodies [microbes], it is a consoling hope that Science will not always remain powerless before such enemies.
Quote by -Louis Pasteur
"Freedom of thought is best promoted by the gradual illumination of men’s minds which follows from the advance of science."
Quote by -Charles Darwin
"We can allow satellites, planets, suns, universe, nay whole systems of universe, to be governed by laws, but the smallest insect, we wish to be created at once by special act."
Quote by -Charles Darwin
"We know we cannot be kind to animals until we stop exploiting them -- exploiting animals in the name of science, exploiting animals in the name of sport, exploiting animals in the name of fashion, and yes, exploiting animals in the name of food."
Quote by -Cesar Chavez
"The work of science is to substitute facts for appearances, and demonstrations for impressions."
Quote by -John Ruskin
"There are as many atoms in one molecule of DNA as there are stars in a typical galaxy."
Quote by -Carl Sagan
"Science is a way to call the bluff of those who only pretend to knowledge. It is a bulwark against mysticism, against superstition, against religion misapplied to where it has no business being."
Quote by -Carl Sagan
"The immense distances to the stars and the galaxies mean that we see everything ins pace int he past, some as they were before the Earth came to be. Telescopes are time machines."
Quote by -Carl Sagan
"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."
Quote by -Carl Sagan
"Skeptical scrutiny is the means, in both science and religion, by which deep thoughts can be winnowed from deep nonsense."
Quote by -Carl Sagan
"Every kid starts out as a natural-born scientist, and then we beat it out of them. A few trickle through the system with their wonder and enthusiasm for science intact."
Quote by -Carl Sagan
"And you are made of a hundred trillion cells. We are, each of us, a multitude."
Quote by -Carl Sagan
"It is the tension between creativity and skepticism that has produced the stunning and unexpected findings of science."
Quote by -Carl Sagan
"A galaxy is composed of gas and dust and stars - billions upon billions of stars. Every star may be a sun to someone."
Quote by -Carl Sagan
"If we are merely matter intricately assembled, is this really demeaning? If there's nothing here but atoms, does that make us less or does that make matter more?"
Quote by -Carl Sagan
"In the vastness of space and the immensity of time, it is my joy to share a planet and an epoch with Annie. [Dedication to Sagan's wife, Ann Druyan, in Cosmos]"
Quote by -Carl Sagan
"We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology."
Quote by -Carl Sagan
"There are no forbidden questions in science, no matters too sensitive or delicate to be probed, no sacred truths."
Quote by -Carl Sagan
"The beauty of a living thing is not the atoms that go into it, but the way those atoms are put together."
Quote by -Carl Sagan
"Science is not only compatible with spirituality; it is a profound source of spirituality."
Quote by -Carl Sagan
"The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff."
Quote by -Carl Sagan
"Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another."
Quote by -Carl Sagan
"Mars, we know, was once wet and warm. Was it home to life? And what can living and learning to work on its rust-colored surface teach us about the future of our own planet, Earth? Answering those mysteries may hold the key to our future."
Quote by -Buzz Aldrin
"As we begin to have landings on the moon, we can alternate those with vertical launch of similar crew modules on similar launch vehicles for vertical-launch tourism in space, if you want to call it that... adventure travel."
Quote by -Buzz Aldrin
"Any observations from the Moon or a sense of realising this or that about the greater meaning of things wasn't as influential for me as the experience of coming back and dealing with being a person who's been to the Moon."
Quote by -Buzz Aldrin
"We need to begin thinking about building permanence on the Red Planet, not just have voyagers do some experiments, plant a flag and claim success. Having them go there, repeat this, in my view, is dim-witted. Why not stay there?"
Quote by -Buzz Aldrin
"When you go to Mars, you need to have made the decision that you're there permanently. The more people we have there, the more it can become a sustaining environment. Except for very rare exceptions, the people who go to Mars shouldn't be coming back. Once you get on the surface, you're there."
Quote by -Buzz Aldrin
"The purpose of going to Mars is for humans to first begin to occupy, permanently, another planet in the solar system. The astronauts or pilgrims, whatever you might call them, are going to be very historically unique human beings."
Quote by -Buzz Aldrin
"Just as Mars - a desert planet - gives us insights into global climate change on Earth, the promise awaits for bringing back to life portions of the Red Planet through the application of Earth Science to its similar chemistry, possibly reawakening its life-bearing potential."
Quote by -Buzz Aldrin
"What are you going to do with astronauts who first reach the surface of Mars and then turn around and rocket back home-ward? What are they going to do, write their memoirs? Would they go again? Having them repeat the voyage, in my view, is dim-witted. Why don't they stay there on Mars?"
Quote by -Buzz Aldrin
"By refocusing our space program on Mars for America's future, we can restore the sense of wonder and adventure in space exploration that we knew in the summer of 1969. We won the moon race; now it's time for us to live and work on Mars, first on its moons and then on its surface."
Quote by -Buzz Aldrin
"NASA's been one of the most successful public investments in motivating students to do well and achieve all they can achieve, and it's sad that we are turning the program in a direction where it will reduce the amount of motivation it provides to young people."
Quote by -Buzz Aldrin
"There's no doubt who was a leader in space after the Apollo Program. Nobody came close to us. And our education system, in science, technology, engineering and math, was at the top of the world. It's no longer there. We're descending rather rapidly."
Quote by -Buzz Aldrin
"You need propellants to accelerate toward Mars, then to decelerate at Mars, again to re-accelerate from Mars to Earth, and finally to decelerate back at Earth. Accordingly, the mass of these required propellants, in short, drives our need for innovative launch vehicles."
Quote by -Buzz Aldrin
