Pattern-Seeking Through Play
Meredith's worldplay was shot through with yet another well-recognized ingigredienlent of creative thinking, the comparison and synthesis of two or more unlike things. As the mathematician and poet Jacob Bronowski famously expressed it, the discoveries of science and of art "are explorations—^more, are explosions, of a hidden likeness The same holds true for the insights generated in worldplay. Documents of play in Lewis, like many a child, combined the animal and the human in Lord Big. Una... 1

Changing Spelling has Happened in the Past
Objection to simplified spelling has been made on the
supposition that it "wil cut us off from the literature
of the past," meaning that those taught in the new way
wil be unable to read the books red today. This can
not be so, because the present spelling wil be no more
difficult to read by one who has learnd to spel the new
way, than is the new spelling by one who has learnd
the old way. Children who hav learnd to spel in the
simplified way wil, in fact, read the books printed

Knowledge Grows Faster Than Compound Interest
Remember that accumulated knowledge, like accumulated capital, increases at compound interest: but it differs from the accumulation of capital in this; that the increase of knowledge produces a more rapid rate of progress, whilst the accumulation of capital leads to a lower rate of interest. Capital thus checks its own accumulation: knowledge thus accelerates its own advance. Each generation, therefore, to deserve comparison with its predecessor, is bound to add much more largely to the commo...It accelerates beyond the comparatively stunted growth of wealth.

Simple Explanation of Big O Notation
The simplest definition I can give for Big-O notation is this:
Big-O notation is a relative representation of the complexity of an algorithm.
There are some important and deliberately chosen words in that sentence:
relative: you can only compare apples to apples. You can't compare an algorithm to do arithmetic multiplication to an algorithm that sorts a list of integers. But two algorithms that do arithmetic operations (one multiplication, one addition) will tell you something meaningful;

Observing a Slot Machine
[The] weakness of biological balance studies has aptly been illustrated by comparison with the working of a slot machine. A penny brings forth one package of chewing gum; two pennies bring forth two. Interpreted according to the reasoning of balance physiology, the first observation is an indication of the conversion of copper into gum; the second constitutes proof.Folksonomies: observation experimentation

The Importance of the Velocity of Light
The velocity of light is one of the most important of the fundamental constants of Nature. Its measurement by Foucault and Fizeau gave as the result a speed greater in air than in water, thus deciding in favor of the undulatory and against the corpuscular theory. Again, the comparison of the electrostatic and the electromagnetic units gives as an experimental result a value remarkably close to the velocity of light–a result which justified Maxwell in concluding that light is the propagation...Folksonomies: speed of light light

Gravity is an Extremely Feeble Force
...imagine holding an electron in your left hand and another electron in your right hand and bringing
these two identical electrically charged particles close together. Their mutual gravitational attraction will favor their getting closer
while their electromagnetic repulsion will try to drive them apart. Which is stronger? There is no contest: The electromagnetic
repulsion is about a million billion billion billion billion (10 to the 42th) times stronger! If your right bicep represents the s...In comparison to the other forces holding the Universe together.

What We Have Discovered
What has been done is little—scarcely a beginning; yet it is much in comparison with the total blank of a century past. And our knowledge will, we are easily persuaded, appear in turn the merest ignorance to those who come after us. Yet it is not to be despised, since by it we reach up groping to touch the hem of the garment of the Most High.Folksonomies: knowledge

The Wonder of X-Rays Affecting a Photographic Plate
But in its [the corpuscular theory of radiation] relation to the wave theory there is one extraordinary and, at present, insoluble problem. It is not known how the energy of the electron in the X-ray bulb is transferred by a wave motion to an electron in the photographic plate or in any other substance on which the X-rays fall. It is as if one dropped a plank into the sea from the height of 100 ft. and found that the spreading ripple was able, after travelling 1000 miles and becoming infinite... 1 notes

Newton's Discovery of Gravity as an Example of Induction ...
All the knowledge we possess of external objects is founded upon experience, which furnishes facts; and the comparison of these facts establishes relations, from which induction, the intuitive belief that like causes will produce like effects, leads to general laws. Thus, experience teaches that bodies fall at the surface of the earth with an accelerated velocity, and with a force proportional to their masses. By comparison, Newton proved that the force which occasions the fall of bodies at t... 1 notes
