Isaac Newton

If anyone offers conjectures about the truth of things from the mere possibility of hypotheses, I do not see by what stipulation anything certain can be determined in any science, since one or another set of hypotheses may always be devised which will appear to supply new difficulties.

English Mathematician

Gulzar

A film carries six fine arts - it consists of architecture, painting, music, writing or literature, photography and performance. It's a conjecture of all these things and yet based on literature.

Indian Poet

Paul Davies

Scientists have no agreed theory of the origin of life - plenty of scenarios, conjectures and just-so stories, but nothing with solid experimental support.

British Writer

Hannes Alfven

We have to learn again that science without contact with experiments is an enterprise which is likely to go completely astray into imaginary conjecture.

Swedish Scientist

Geoffrey West

Sometimes, I look out at nature and I think, 'Everything here is obeying my conjecture.' It's a wonderfully narcissistic feeling.

British Physicist

Richard Dawkins

If there are other worlds elsewhere in the universe, I would conjecture they are governed by the same laws of natural selection.

English Scientist

Nigel Lawson

However useful computer models may be, the one thing they cannot be is evidence. Computer climate models are simply conjectures.

British Politician

Jonathan Raymond

You can't know what the future holds, though you might conjecture on it, and if you're psychic, you might venture a guess.

American Writer

Ruth Wilson

People don't know what goes on in my private life, so they have to make conjecture from something that is photographed.

English Actress

William Hazlitt

You know more of a road by having traveled it than by all the conjectures and descriptions in the world.

English Critic

Use 'conjecture' to emphasize the uncertainty or incompleteness of the idea.

Uncertainty Emphasis

'Conjecture' involves predictions or explanations that are not confirmed as facts.

Not Facts

'Conjecture' may imply a lack of reliability or seriousness in a claim.

Negative Connotation

Use 'conjecture' as a verb when suggesting a hypothesis in the absence of full information.

Hypothesizing

'Conjecturing' is appropriate for informal analyses but less so for formal conclusions.

Informal Analysis

When 'conjecturing', one does not rely on solid evidence but on intuition or incomplete data.

Not Evidence-Based

 There's more. We just pointed out that the set of decimal numbers -- that is, the real numbers -- is a bigger infinity than the set of whole numbers. Cantor wondered whether there are infinities of different sizes between these two infinities. He didn't believe there were, but couldn't prove it. Cantor's conjecture became known as the continuum hypothesis.

 that I could potentially be a terrorist spy. And whether this statement was made in jest, conjecture or just plain ignorance, the statement really hurt. It was also a side reminder that some people are going to judge me and see me as dangerous without even knowing me. Christians around the table shared they were there to protect

 This is a lot of conjecture, but it's food for thought. Now, I'd like to share with you for a moment my experience, and using my smarts and that of my colleagues, to try and get this kind of information. We're diving, we can't stay underwater forever because we can't breathe it,

 This idea, called reticular theory, imagined the nervous system as a massive web of tissue that physically connected every nerve cell in the body. Reticular theory captivated the field with its elegant simplicity. But soon, a young artist would cut through this conjecture,

 one of the fundamental problems of cognitive science with a single witticism. He said, "There's something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment in fact."

 Well, we mathematicians devote ourselves to come up with theorems. Eternal truths. But it isn't always easy to know the difference between an eternal truth, or theorem, and a mere conjecture.
