Reading Wars of the 1990s
WHOLE-language theory holds that learning to read and write English is analogous to learning to speak it -- a natural, unconscious process best fostered by unstructured immersion. In an atmosphere rich in simple printed texts and in reading aloud, small children make a wondrous associative leap from knowing the alphabet to being able to read whole words. Their minds receive print as if each word were a Chinese ideogram. If a word is unfamiliar it can be skipped, guessed at, or picked up from ... 1

notesSite Words VS Phonics. If English was phonetical, we could focus on one strategy, but because many spellings don't match their pronunciations we must also memorize Sight Words as if they were Chinese ideograms.

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 notes

Kindergarden: Garden of Children
Kindergarten means a garden of children, and Froebel, the inventor of it, or rather, as he would prefer to express it, the discoverer of the method of Nature, meant to symbolize by the name the spirit and plan of treatment. How does the gardener treat his plants? He studies their individual natures, and puts them into such circumstances of soil and atmosphere as enable them to grow, flower, and bring forth fruit,-- also to renew their manifestation year after year.

Human Respiration is Not a Source of Carbon Emissions
That's not a problem. The CO2 that's released by humans (and animals) is produced by metabolising carbon from food, and the food comes from plants that have been grown recently. During their growth, the plants have absorbed an equivalent amount of CO2 from the atmosphere. Even when eating meat, the animals are typically only a few years old and were fed on recently grown plants. In contrast, the cars run on fossil fuels that are hundreds of million years old. 1 notes

Global Warming is a Land Management Issue
One of the main causes of warming is the increase of carbon dioxide in the atmosphere resulting from our burning of fossil fuels such as oil and coal and natural gas. To understand the movement of carbon through the atmosphere and biosphere, we need to measure a lot of numbers. I do not want to confuse you with a lot of numbers, so I will ask you to remember just one number. The number that I ask you to remember is one hundredth of an inch per year. Now I will explain what this number means. ... 1 notes
notesWith proper land management, we can pull the excess carbon from the atmosphere and into biomass.

Physiological Effects from Exposure to a Vaccum
Vacuum doesn’t have a temperature of its own,
so space is not really that cold. It’s a great insulator
too, meaning that your core body heat doesn’t get
sucked away. Without an atmosphere to transfer heat
away, the risk of exposure is somewhat mitigated. The saliva on your tongue may boil off, as it’s not
pressurized like your blood is, and you may get some
frost on your skin. Sunburn from direct contact with
the sun’s ultraviolet rays is a more immediate danger
than perishing from ... 1 notes

The Energy Efficiency of Spheres
Environment-controlling buildings gain or lose their energy as "heat o cool" only through their containing surfaces. Spheres contain the most vololume with the least surface—i.e., have the least possible surface-to-volume ratio. Every time we double the diameter of a spherical structure, we in¬ crease its contained atmosphere eightfold and its enclosing surface onlyily fourfold. When doubling the diameter of our sphere, we are not changiring the size of the contained molecules of atmospher... 1 notes

Climate Change Science is Based on an 1896 Paper
Our understanding that increasing carbon dioxide levels in the atmosphere could change the climate is not new. The relationship between carbon dioxide, water vapor, and climate was first laid out in detail in 1896 by the Swedish physicist Svante Arrhenius, who estimated that a doubling of carbon dioxide levels would cause global warming of 4.9° to 6.1°C. In his landmark paper, Arrhenius reported that "a simple calculation shows that the temperature in the arctic regions would rise about 8°...Reference to the original paper that started Climate Change Science.

The ENMOD Treaty
There are also major foreign policy concerns, beginning with the international ENMOD treaty—the Convention on the Prohibition of Military or Any Other Hostile Use ot Environmental Modification Techniques, ratified by the United Nations in 1978 in response to the United States' use of silver iodide cloud seeding to alter the weather over the Ho Chi Minh Trail during the Vietnam War. Operation Popeye was an effort to "make mud, not war" to slow North Vietnamese supply lines by lengthening the...Folksonomies: war geoengineering

Experiment Demonstrating Plants Produce Breathable Air
When air has been freshly and strongly tainted with putrefaction, so as to smell through the water, sprigs of mint have presently died, upon being put into it, their leaves turning black; but if they do not die presently, they thrive in a most surprizing manner. In no other circumstances have I ever seen vegetation so vigorous as in this kind of air, which is immediately fatal to animal life. Though these plants have been crouded in jars filled with this air, every leaf has been full of life;...Folksonomies: experimentation
