- ... one knows of their technological capabilities . They may be far more advanced compared to technology on earth. Other questions that remain unanswered as how they travel and what their made out of. It is a great mystery to how UFOs travel and what they are made out of.

There were near one thousand pages of documents released. An important memo was foundin these papers. . . .Deputy Director for the CIA, dated November 1952 says bluntly: sightings of unexplained objects at great altitude and traveling at high speeds in the vicinity of major United States defense, are such a nature that they are not attribute to natural phenomena or known types of Arial vehicles(Brookesmith 35) The ...
- 6414: The Depletion of Ozone Layer
- ... not flammable, non-toxic, and non-corrosive, they can be used in a variety of products without the worry of drastic changes in their properties or the threat of fire and other hazards. But the great stability of CFCs also allows them to survive for many years and pile up in the troposphere. As a result, some CFCs eventually move into the stratosphere, where they can destroy ozone. The scientists, who ... agencies were analyzing data and developing reports on the ozone depleting effects of various halogens. Since studies during the late 1970s and early 1980s suggested that the ozone layer might not be in as a great a danger as once believed. One report from the National Academy of Sciences, indicated that human and naturally produced compounds, such as carbon dioxide, methane and nitrogen oxides, in the atmosphere could help to slow ...
- 6415: Oxygen
- ... in pressurized cylinders or, as is often the case when large amounts are involved, through pipelines to nearby industrial plants. Relationship To Life Sciences Most organisms depend on oxygen to sustain their biological processes. The great majority of living organisms fall into two categories. In the first category are the higher plants and the photosynthetic bacteria. These organisms utilize light energy through PHOTOSYNTHESIS to combine carbon dioxide and water (or, infrequently ... more than one crystal structure (polymorphism). The most oxidized compound, titanium, is widely used in the RUTILE form as a white pigment in paints. Ternary oxides, consisting of two metallic elements plus oxygen, are of great interest to solid-state scientists. For example, compounds such as the SPINELS and the PEROVSKITES are studied extensively because of their interesting magnetic and electrical properties. Examples of important ternary oxides are the magnetic FERRITES ...
- 6416: Stop Pollution
- ... lives on carbondioxide dissolved in the seawater. Oceans absorb up to 2 billion tons of carbon dioxide a year, making the sea one of the Earth's key defenses against global warming. Oceans have a great potential for heat storage, the top two or three meters hold as much heat as the entire atmosphere. This warmth is continuously redistributed by surface and convection currents. Without the ocean there would be no ... and polluted many water bodies, this can't go on for much longer. If it does we will be contributting even more to the weakening of our ecosystem.

He saw that his theory supplanted the views of Lamarck ... reference material consisted of works of Sir Charles Lyell, a British geologist (he developed a concept termed uniformitarianism which suggested that geological phenomena could be explained by prevailing observations of natural processes operating over a great spans of time - he has been accused synthesizing the works of others30) who was the author of geologic texts that were required reading throughout the 19th century including Principals of Geology, which along with his ...
- 6418: Water and Its Importance
- ... do not freeze to death in the winter. Thermal conductivity is the ability of a substance to retain or lose heat as needed. Water is an excellent heat bank. Though it loses or gains a great amount of heat, its temperature still changes very little. This allows water to gain or lose a great amount of energy but still resist a change of temperature. Like most of waters many properties, this is also due to hydrogen bonding; because energy is used to break the hydrogen bonds and lost when ...
- 6419: The Origin of Life
- ... would like to discuss two that result from the nature of scientific tradition. The first of these is an issue of methodology. In its laudable insistence upon experience, accurate observation and verifiability, science has placed great emphasis upon measurement. To measure something is to experience it in a certain dimension, a dimension in which we can make observations of great accuracy, which are repeatable by others. The use of measurement has enabled science to make enormous strides in the understanding of the material universe. But by virtue of its success, measurement has become kind of ...
- 6420: Botany and Botanists
- ... to surrounding plant areas. New and improved technology is helping us solve these problems, but they will still need young minds to use that technology for the better good of humanity.
