Complexity in Systems
On the far left are fixed systems that remain unchanging.hand, a screen that is full of random static would be completely The relationships between their elements are always the chaotic, with the color of a dot at one moment having nothing same. The black, unchanging TV screen is a good image for this kind of system.
To the right of fixed systems in the chart are periodic ones. Periodic systems are simple systems that repeat the same patterns endlessly. The simple two-building version of the... 1

Children's Art Has Its Own Logic
Even simple scribbles are meaningful. While it was once thought that kids only scribbled to experience the physical sensation of moving their arm along the page, “now it’s been shown that when children are scribbling … they’re representing through action, not through pictures,” said Boston College’s Winner. “For example, a child might draw a truck by making a line fast across the page and going ‘zoom, zoom,’ and so it doesn’t look like a truck when the child is done, but i... 1 notes

Astronomy affords the most extensive example of the connection of physical sciences. In it are combined the sciences of number and quantity, or rest and motion. In it we perceive the operation of a force which is mixed up with everything that exists in the heavens or on earth; which pervades every atom, rules the motion of animate and inanimate beings, and is a sensible in the descent of the rain-drop as in the falls of Niagara; in the weight of the air, as in the periods of the moon. 1 notes

Proof that Objects Fall at the Same Rate
Salv.
But, even without further experiment, it is possible to prove clearly, by means of a short and conclusive argument, that a heavier body does not move more rapidly than a lighter one provided both bodies are of the same material and in short such as those mentioned by Aristotle. But tell me, Simplicio, whether you admit that each falling body acquires a definite speed fixed by nature, a velocity which cannot be increased or diminished except by the use of force [violenza] or resistance.... 1 notes

How Intuition Messed Up the Laws of Motion
A most fundamental problem, for thousands of years
wholly obscured by its complications, is that of motion.
All those motions we observe in nature that of a
stone thrown into the air, a ship sailing the sea, a cart
pushed along the street are in reality very intricate.
To understand these phenomena it is wise to begin
with the simplest possible cases, and proceed gradually
to the more complicated ones. Consider a body at rest,
where there is no motion at all. To change the position
o... 1 notes

keyframe
n. a moment that seemed innocuous at the time but ended up marking a diversion into a strange new era of your life—set in motion not by a series of jolting epiphanies but by tiny imperceptible differences between one ordinary day and the next, until entire years of your memory can be compressed into a handful of indelible images—which prevents you from rewinding the past, but allows you to move forward without endless buffering. 1 notes
notesA moment that marks a transition in our lives, but really serves as a signifier for a long gradual change.

Science, Religion, and the Motion of the Earth
We may distinguish the progress of each science as it is in itself, which has no other limit than the number of truths it includes within its sphere, and the progress of a nation in each science, a progress which is regulated first by the number of men who are acquainted with its leading and most important truths, and next by the number and nature of the truths so known.
In fine, we are now come to that point of civilization, at which the people derive a profit from intellectual knowledge, n... 1 notes

The Geoscope
Because the real planet Earth is revolving around its north-south polar axis, so, too, is mini-Earth. They are both thus revolving without effecting any change of the observed position of Polaris—the North Star—in respect to mini-Earth's north pole. Therefore, the observer at the center of the Geoscope feels spontaneously the celestial fixity not only of Polaris but also of all the other stars as seen outwardly through the Geoscope's triangular windows. Because outwardly of Geoscope's equ... 1 notes

Newton's Definitions
Def. I.
The Quantity of Matter is the measure of the same, arising from its density and bulk conjunctly.
THUS AIR of a double density, in a double space, is quadruple in quantity; in a triple space, sextuple in quantity. The same thing is to be understood of snow, and fine dust or powders, that are condensed by compression or liquefaction; and of all bodies that are by any causes whatever differently condensed. I have no regard in this place to a medium, if any such there is, that freely pe...

Laws of Motion
LAW I.
Every body perseveres in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed thereon.
Projectiles persevere in their motions, so far as they are not retarded by the resistance of the air, or impelled downwards by the force of gravity. A top, whose parts by their cohesion are perpetually drawn aside from rectilinear motions, does not cease its rotation, otherwise than as it is retarded by the air. The greater bodies... 1 notes
