Notwithstanding all that has been discovered since Newton's time, his saying that we are little children picking up pretty pebbles on the beach while the whole ocean lies before us unexplored remains substantially as true as ever, and will do so though we shovel up the pebbles by steam shovels and carry them off in carloads.
Interpretation
Knowledge is vast and our understanding is limited, much like children playing on a beach with tiny stones.
This quote by Charles Sanders Peirce reflects on the nature of human knowledge and discovery. Even with advancements in science and technology since Newton's time, our understanding remains minimal compared to the vastness of what is yet to be explored. The metaphor of children on a beach symbolizes how we may be fascinated by small discoveries (the pebbles), while the larger, more profound truths (the ocean) remain largely unknown and uncharted. This underscores the humility that should accompany our pursuit of knowledge and the acknowledgment that there is always more to learn.
In practice
In a classroom setting to encourage students to be curious about the unknown.
The final upshot of thinking is the exercise of volition, and of this thought no longer forms a part; but belief is only a stadium of mental action, an effect upon our nature due to thought, which will influence future thinking.
My language is the sum total of myself.
All the evolution we know of proceeds from the vague to the definite.
The third class consists of men to whom nothing seems great but reason. If force interests them, it is not in its exertion, but in that it has a reason and a law. For men of the first class, nature is a picture; for men of the second class, it is an opportunity; for men of the third class, it is a cosmos, so admirable, that to penetrate to its ways seems to them the only thing that makes life worth living. These are the men whom we see possessed by a passion to learn.
A quality is something capable of being completely embodied. A law never can be embodied in its character as a law except by determining a habit. A quality is how something may or might have been. A law is how an endless future must continue to be.
In all the works on pedagogy that ever I read β and they have been many, big, and heavy β I don't remember that any one has advocated a system of teaching by practical jokes, mostly cruel. That, however, describes the method of our great teacher, Experience.
I do not want to drive across a bridge designed by an engineer who believed the numbers in structural stress models are relative truths.
Water is commonly regarded as the 'solvent of life,' since our bodies are 70% water. All other vertebrates, invertebrates, microbes, and plants are also primarily water. The organization of water within biological compartments is fundamental to life, and the aquaporins serve as the plumbing systems for cells.
Magnitude may be compared to the power output in kilowatts of a [radio] broadcasting station; local intensity, on the Mercalli or similar scale, is then comparable to the signal strength noted on a receiver at a given locality. Intensity, like signal strength, will generally fall off with distance from the source; it will also depend on local conditions at the point of observation, and to some extent on the conditions along the path from source to that point.
During the past three years spectacular progress has been made in increasing wheat, rice, and maize production in several of the most populous developing countries of southern Asia, where widespread famine appeared inevitable only five years ago
If we use our fuel to get our power, we are living on our capital and exhausting it rapidly. This method is barbarous and wantonly wasteful, and will have to be stopped in the interest of coming generations. The heat of the sun's rays represents an immense amount of energy vastly in excess of waterpower...The sun's energy controlled to create lakes and rivers for motive purposes and transformation of arid deserts into fertile land.
Yet is it possible in terms of the motion of atoms to explain how men can invent an electric motor, or design and build a great cathedral? If such achievements represent anything more than the requirements of physical law, it means that science must investigate the additional controlling factors, whatever they may be, in order that the world of nature may be adequately understood.
