Discussions On Darwin
1803 Words - 7 Pages.... end the feud among educated men because many now put their trust in this new “theory of evolution”. Unfortunately, this revolutionary new theory threatened the religious beliefs about creation and soon a new rivalry emerged between the creationists and evolutionists.
According to Charles Darwin man began as one of a few species on this new planet striving for survival. However, man was better equipped with certain traits that allowed him to pass through the filter of natural selection. Man was supplied with both physical and intellectual traits that were responsible for allowing him to surmount the other species living beside him. He was able to use his physical traits ....

The Use Of Pollen Analysis In
930 Words - 4 Pages.... which are truly hostile to this shell are abrasion, such as may be the case on sandy sites, and oxidation. However, the most favourable conditions for preservation of the pollen record are acidic, anaerobic sites such as peat bogs. This high degree of survivability combines with another factor inherent in the nature of pollen - the large amount produced - to make pollen analysis one of the most important tools available to the archaeologist. Though one further factor in the make-up of pollen enhances its value, namely the wide morphological variation between pollen from different plant species, most of which can be detected and classified using normal laboratory equipmen ....

Environmental Protection
1958 Words - 8 Pages.... be distinguished from that of any other species. This position, most often espoused by individuals whose other views are curiously much more anthropocentric, is contrary to some well established facts. Unlike other creatures that have inhabited the Earth, human beings are the first to possess the technological ability to cause wholesale extermination of species, genera or even entire families of living creatures. This process is accelerating. Wildlife management efforts initiated during this century have been unsuccessful in stemming the tide.
Most public attention given to endangered species has focused on mammals, birds, and a few varieties of trees. Ecologists recogn ....

The Effects Of Antibiotics On Bacterial Growth
1287 Words - 5 Pages.... Most of them are
phototrophic, i.e. they use the sun’s energy as food through the process of
photosynthesis.
Another classification of bacteria is according to their need of oxygen
to live. Those who do require oxygen to live are considered aerobes. The
bacteria who don’t use oxygen to live are known as anaerobes.
The shape of specific bacteria provides for the next step in the
identification process. Spherical bacteria are called cocci; the bacteria that
have a rodlike shape are known as bacilli; corkscrew shaped bacteria are
spirilla; and filamentous is the term for bacteria with a threadlike appearance.
Hans Christian Joachim Gram, a Danish microbiologist, d ....

Lightning
1211 Words - 5 Pages.... accurate statistics on injuries and fatalities since a systematic compilation of information on casualties does not exist. Many case histories show heart damage. Inflated lungs and brain damage have also been observed from fatalities. Loss of consciousness, amnesia, paralysis and burns are reported by many who have survived. Deaths and injuries to livestock and other animals, thousands of forest and brush fires, as well as millions of dollars in damage to buildings, communications systems, power lines, and electrical systems are also the result of . Finally, the threat of causes many work stoppages and lost production increasing the time and cost required to

Nuclear Power
533 Words - 2 Pages.... and all exposure to
radiation is harmful to human health. In this critique I plan on reviewing
some of the major issues brought up by each side and try to show how each
author has distorted or skewed data. Then I plan on giving my
interpretation and opinion on the future of nuclear power.
Dr. Gofman seems to have many confusing ideas about the concept of
nuclear power. First of all he shoots down the government for giving money
to nuclear industries and claims that doing this is "totally inappropriate
for government." I don't know if Dr. Gofman understands that we are kind of
running out of energy sources, and until we better develop things like
solar power to make them ....

Lasers 3
809 Words - 3 Pages.... laser. Charles Townes,
a scientist, wanted to see if microwaves, which are very similar to light, might be stimulated to produce an amplified beam by the process that Albert Einstein described. Townes was successful in 1954 when he constructed what he called the maser (microwave amplification by stimulated emission of radiation). The maser amplifies the number of photons that cause microwaves.
After the invention of the maser many scientists became interested in the idea of building an optical maser, which soon received the name laser (light amplification by stimulated emission of radiation). Townes paired with Arthur Schawlow, two Soviets, Nikolai Basov and Aleksander Prok ....
