Certain periods in history suddenly lift humanity to an observation point where a clear light falls upon a world previously dark.

It is my intention to present - through the medium of photography - intuitive observations of the natural world which may have meaning to the spectators.

We must trust to nothing but facts: these are presented to us by nature and cannot deceive. We ought, in every instance, to submit our reasoning to the test of experiment, and never to search for truth but by the natural road of experiment and observation.

People who look for the first time through a microscope say, 'Now I see this, and then I see that,' and even a skilled observer can be fooled. On these observations I have spent more time than many will believe, but I have done them with joy, and I have taken no notice of those who have said, 'Why take so much trouble,' and, 'What good is it?'

Please bear in mind that my observations and thoughts are the outcome of my own unaided impulse and curiosity alone; for, besides myself, in our town there be no philosophers who practice this art, so pray, take not amiss my poor pen and the liberty I here take in setting down my random notions.

The fundamental difficulty in myothermic observations is the smallness of the changes involved and their rapidity.

Teachers support evaluations based on multiple measures: student growth, classroom observation and feedback from peers and parents.

It is also a good rule not to put overmuch confidence in the observational results that are put forward until they are confirmed by theory.

Good men, whether they be Christians or rationalists, do not desire to discriminate between races, but the distinctions implanted by Nature are too conspicuous to escape the observation of our senses.

We may take it to be the accepted idea that the Mosaic books were not handed down to us for our instruction in scientific knowledge, and that it is our duty to ground our scientific beliefs upon observation and inference, unmixed with considerations of a different order.

In the numerous observations made in my laboratory upon this object, we have only once seen a combination of vessels in which there might be a direct communication between a small artery and a vein, though the two observers could not come to a final conclusion on the point.

Every science consists in the coordination of facts; if the different observations were entirely isolated, there would be no science.

I'm an only child, so I don't come from a big family. But it has been my observation from friends who do come from big families that usually, when you have a family fight, on the back end you come out better and stronger for it.

Growing up, I wasn't the most vocal kid in the world. I feel like I learned through observation, and usually, when you're watching things, you're not speaking. That sort of metastasized in a way that I began to participate less and less in the world.

Based on a lifetime of observations and a few decades in the markets, I understand that societies, beliefs and fashions all move in long arcs of time. We call these arcs several things: cycles, periods, eras.

My duty is that of a chronicler; and if I perform that conscientiously, the lessons which my observations suggest will need no pointing out.

A novel is no mere assemblage of gears; it is a wild and living being. And how are you to discern the intentions of a creature - to discover its true nature - other than by close and respectful observation?

Some may look on my work as being corny or old hat and wonder if my observations on the typical family are passe, what with the single-parent family and mixed family units.

My comedy comes from the actual music itself - they're observational musical gags. I could take the music away and it would just be some words.

I just use my life story as a kind of device on which to hang comic observations. It's not my interest or instinct to tell the world anything pertinent about myself or my family.

I've been writing all these books that have been largely autobiographical and yet, really, they don't tell you anything about me. I just use my life story as a kind of device on which to hang comic observations. It's not my interest or instinct to tell the world anything pertinent about myself or my family.

I think there's value in experience and observations that link past to present.

Tax dollars intended for science education must not be used to teach creationism as any sort of real explanation of nature, because any observation or process of inference about our origin and the nature of the universe disproves creationism in every respect.

Your success is in your point of view. It's your life that you're talking about; it's your observations. That's the best lesson that I ever had.

You have to have some kind of power of observation, almost like a trained observer.

I act by observation.

I like jokes, but Ray and I, we never did jokes. We weren't in that line of humor. We each contributed our own kind of observations. I'm glad to have people look at and laugh at and respect and get some creative juice out of what we did by observing.

I can encourage my daughter to love her body, but what really matters are the observations she makes about my relationship with my own body.

The real reason why general relativity is widely accepted is because it made predictions that were borne out by experimental observations.

For several days in July of 2012, Greenland surface ice cover melted more than at any time in 30 years of satellite observation. During that month, an estimated 97% of the ice sheet thawed.

The five steps in teaching an employee new skills are preparation, explanation, showing, observation and supervision.
