6,729. To explain all Nature is too difficult a task for any one man or even for any one Age. Tis much better to do a little with certainty and leave the rest for others that come after you than to explain all things by conjecture without making sure of any thing. (Knowledge & Science & Isaac Newton) Isaac Newton
2,373. Every body continues in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed upon it. (Physics & Newton & Action & Motion & Science & Laws & Gravity) Isaac Newton, Principia Mathematica, Laws of Motion I
48,766. The alternation of motion is ever proportional to the motive force impressed; and is made in the direction of the right line in which that force is impressed. (Physics & Newton & Action & Motion & Science & Laws & Gravity) ibid. Laws of Motion II
4,478. To every action there is always opposed an equal reaction; or, the mutual actions of two bodies upon each other are always equal, and directed to contrary parts. (Physics & Newton & Action & Motion & Science & Laws & Gravity) ibid. Laws of Motion III
30,791. In the summer of 1693 Isaac Newton was having a catastrophic nervous breakdown. He had always suffered intense bouts of depression and mania. (England & Great Britain & Newton & Depression & Science) Tristram Hunt, Great Britons: Isaac Newton
30,792. When he was still a young boy his mother left him ... Isaac had to stay behind at Woolsthorpe. He was effectively abandoned. (England & Great Britain & Newton & Science & Rejection) ibid.
30,793. His favourite book was The Mysteries of Nature & Art. (England & Great Britain & Newton & Science) ibid.
30,794. A lonely schoolboy was laying the foundations of modern science. (England & Great Britain & Newton & Science) ibid.
30,795. He then drew up a list entitled Some Problems in Philosophy. Under forty-five different headings he identified what he saw as the great unanswered questions of science. (England & Great Britain & Newton & Science) ibid.
30,796. The image of the lone scientists in his garden unlocking the mysteries of the universe resonates through history ... Rather than developing a full theory of Gravity he put it to one side and rather focused his mind on a completely different branch of science: Optics. (England & Great Britain & Newton & Science) ibid.
30,797. Knowledge to him was something sacred and solitary ... He made the world’s first reflecting telescope. (England & Great Britain & Newton & Science & Knowledge) ibid.
30,798. His sense of betrayal and injustice was overwhelming. (England & Great Britain & Newton & Science) ibid.
30,799. Instead became obsessed with the Bible. It seems an extraordinary chance of tack. (England & Great Britain & Newton & Science & Bible) ibid.
30,800. Unknown to others he had been consumed by alchemy ... The Lucasian Professor had become the sorcerer’s apprentice ... He wrote over a million words on alchemy. (England & Great Britain & Newton & Science & Alchemy) ibid.
30,801. He decided to write a definitely guide to the workings of the universe ... At a stroke Newton had changed everything: the cosmos had become knowable, mathematical; it was a staggering achievement. (England & Great Britain & Newton & Science) ibid.
30,802. Philosophae Naturalis Principia Mathematica ... One such first edition was recently sold at auction for £2,000,000. (England & Great Britain & Newton & Science & Book) ibid.
30,803. He was concerned with motion ... Newton was able to devise the three laws of motion. (England & Great Britain & Newton & Science) ibid.
30,804. He left us ideas, ideas that allow us to control the forces of Nature and change our world. Ideas that will always be with us wherever we go. (England & Great Britain & Newton & Science) ibid.
60. How is it that any major religion has looked at science and concluded, ‘This is better than we thought’? The universe is much bigger than our prophets said, grander, more subtle, more elegant. ‘No, no, no!’ they say, ‘My God is a little god and I want him to stay that way.’ A religion old or new that stressed the magnificence of the universe as revealed by modern science might be able to draw forth reserves of reverence and awe hardly tapped by the conventional faiths. (God & Religion & Universe & Science) Professor Carl Sagan
1,037. Extraordinary claims require extraordinary evidence. (Faith & Belief & God & Evidence & Science) Carl Sagan
2,467. Science is a self-correcting process. To be accepted new ideas must survive the most rigorous standards of evidence and scrutiny. (Science & Idea & Evidence) Professor Carl Sagan & Ann Druyan, Cosmos: Heaven and Hell, 1979
2,615. If you wish to make an apple-pie from scratch, you must first invent the universe. (Science & Universe & Apple & Create) Carl Sagan, Cosmos
2,468. A way of sceptically interrogating the universe with a fine understanding of human fallibility. If we are not able to ask sceptical questions, to interrogate those who tell us that something is true, to be sceptical of those in authority, then we’re up for grabs for the next charlatan, political or religious, who comes ambling along. (Science & Sceptics & Universe) Carl Sagan, interview Charlie Rose 27th May 1996
2,475. Who is more humble? The scientist who looks at the universe with an open mind and accepts whatever it has to teach us, or somebody who says everything in this book must be considered the literal truth and never mind the fallibility of all the human beings involved? (Science & Humble & Universe & Bible & Religion) ibid.
2,469. It seems to me what is called for is an exquisite balance between two conflicting needs: the most skeptical scrutiny of all hypotheses that are served up to us and at the same time a great openness to new ideas. (Science & Ideas) Carl Sagan, Skeptical Inquirer 12:1
90,325. The suppression of uncomfortable ideas may be common in religion or politics. But it is not the path to knowledge. And there’s no place for it in the endeavour of science. (Suppression & Idea & Science) Professor Carl Sagan & Ann Druyan, Cosmos: Heaven and Hell 1979
2,472. Science is much more than a body of knowledge. It is a way of thinking. This is central to its success. Science invites us to let the facts in, even when they don’t conform to our preconceptions. It counsels us to carry alternative hypotheses in our heads and see which ones best match the facts. It urges on us a fine balance between no-holds-barred openness to new ideas, however heretical, and the most rigorous skeptical scrutiny of everything — new ideas and established wisdom. We need wide appreciation of this kind of thinking. It works. It’s an essential tool for a democracy in an age of change. Our task is not just to train more scientists but also to deepen public understanding of science. (Science & Knowledge & Think & Fact & Idea & Sceptics & Wisdom & Democracy & Understanding) Carl Sagan, ‘Why We Need to Understand Science’ Skeptical Inquirer 14:3
99,832. We have to find ways to amuse ourselves. We never really get a chance to get down to LA. There’s a lot of sex games on go, wife-swapping and a lot of related nonsense. Scientists really aren’t any different from humankind. Just more inventive, that’s all. (Horror & Science Fiction & Bees & Los Angeles & Science) ibid.
