Reproduction: A Courting To Nature
.... a famed Austrian naturalist, made detailed studies of Greylags and
afterwards showed no hesitation in using words like love, grief and even
embarrassment to describe the behavior of these large, social birds.
At the same time he did not forget that all romance - animal and human - is
tied intimately to natural selection. Natural selection brought on the
evolution of males and females during prehistoric epochs when environmental
change was making life difficult for single-sex species such as bacteria

Could Gambling Save Science: Encouraging An Honest Consensus
.... proposed approach. After this examination, the idea still seems
plausible and worth further study.
INTRODUCTION
After reviewing the discrepancy between what we want from academic
institutions and what we get from current institutions, a market-based
alternative called "idea futures" is suggested. It is described through
both a set of specific scenarios and a set of detailed procedures. Over
thirty possible problems and objections are examined in detail. Finally, a
development strategy is outli .....

Supernova
.... in
100 million years, and the energy expended in ejecting material is much
greater even than this. In many cases, including the Crab nebula supernova,
the stellar remnant left behind after the explosion is a NEUTRON STAR--a
star only a few kilometers in diameter having an enormously large density
and consisting mainly of neutrons--or a PULSAR, a pulsating neutron star.
There are two common types of supernovas, called type I and type II.
Type I occurs among old stars of small mass, whereas type II o .....

Origin Of The Solar System
.... origin of the solar system that have
been advanced during the last three centuries can be classified as either
dualistic or monistic. A common feature of dualistic theories is that
another star once passed close to the Sun, and tidal perturbations between
the two stars drew out filaments of gas from which the planets condensed.
Theories of this type encounter enormous difficulties in trying to account
for modern information about the solar system, and they have generally been
discarded. By contrast, monis .....

Stars
.... the Greek lower-case letter gamma) Ursa
Minoris, and Betelgeuse, in Orion, is gamma Orionis. VARIABLE STARS (those
which periodically change in brightness) have lettered names, such as RR
Lyrae in the constellation Lyra. Fainter stars are known by their numbers
in a catalog; HD 12938 is the 12,938th star in the Henry Draper Catalogue.
CHARACTERISTICS OF STARS
Each star in the universe has its own position, motion, size, mass,
chemical composition, and temperature. Some stars are grouped into clusters .....

Eugenics
.... which was in marriages. In 1905, Indiana passed a law that “forbade the marriage of the mentally deficient, persons having a transmissible disease, and habitual drunkards; required a health certificate of all persons released from institutions, and declared void all marriages contracted in another state in an effort to avoid the Indiana law.”11 Negative eugenics was much more prevalent in society, as it seemed much more practical to eliminate defects than to try to isolate positive characteristics. Th .....

The Metric System
.... Fahrenheit is hard for many people to understand and translate because it is not read in increments of one. Instead it is read having thirty-two degrees Fahrenheit being zero and two hundred and twelve degrees being the boiling point, While the Celsius (metric unit of measure for temperature) is read with one degrees Celsius being the freezing point of water, and one hundred degrees Celsius being the boiling point.
I think that the metric system should be used everywhere in the world because it would ma .....

Hormone Use In Livestock
.... PST.
As pigs grow closer to market weight, they produce less PST, which results in poor feed efficiency. The muscle gain stays fairly constant while more nutrients taken in by the animal are used in fat production causing the animal to require more energy for the production of muscle. Manufactured PST will provide a boost in the natural levels of PST in a maturing pig. If there is more PST, there will be more efficient utilization of feed and fat production will be kept to a minimum.
PST is effe .....

Genetic Engineering, History And Future
.... discovering its possibilities, and answering the moral and safety questions it brings forth, the blanket of fear covering this remarkable technical miracle can be lifted.
The first step to understanding genetic engineering, and embracing its possibilities for society, is to obtain a rough knowledge base of its history and method. The basis for altering the evolutionary process is dependant on the understanding of how individuals pass on characteristics to their offspring. Genetics achieved .....

Copper And Aluminium

The properties that make copper extremely useful include -
Conductivity - Silver is the only better conductor, but is too expensive for common use. Copper also conducts both electricity and heat extremely well, which makes it extremely useful for cooking utensils, radiators, and refrigerators.
Malleability - Copper is highly mal .....

Nuclear Power: Worth The Risks?
.... for the country. It was called progress. Progress also brought with it sickness, mutations, cancer and eventually death to those exposed to high levels of radiation. Government declared that nuclear power is safe and efficient. Also have big Oil corporations who have a lot of money invested in nuclear power and want to see as many plants as possible put into and kept in operation. The truth is that accidents do happen at nuclear power plants and at other facilities all the time. An accident a .....

Changing Undesirable Behaviors
.... on implementing the developed program with the same number of opportunities to escape as the previous four days.
RESULTS
It was determined that the subject would almost always attempt to escape from the house when it was given the opportunity during the first four days. As the days progressed, it's total number of escapes decreased. This could be attributed to the fact that every time it found it's way outside, it was immediately picked up and returned to it's proper location. This is a perfect e .....

Ocean Pollution

Industrial, agricultural, household cleaning, gardening, and automotive products are also polluting our ocean. You wouldn't believe it but all of those products I just named regularly end up in water. About 65,000 chemicals are used commercially in the U.S. Today, with about 1,000 new ones added each year. Only about 300 have been extensively tested for toxic .....

A Study Of B.F. Skinner And Behaviorism
.... Pennsylvania in 1904. He graduated from Hamilton College in 1926. After becoming interested in the works and studies of John B. Watson and Ivan P. Pavlov, he studied with animal learning and functions of the nervous system. He received his Ph.D. in behavioral psychology at Harvard in 1931. In 1936, he then worked as part of the faculty at the University of Minnesota. A few years later in 1939 to 1945, during World War II, he designed the "baby box" or better known to psychologist as the "Skinner box" .....

The Race To The Moon
.... all space programs blended into a secretive military-industrial bureaucracy. Launches were not announced in advance, and only the successes were publicized. (Baker 158-161).
During the early years of the Space Race, success was marked by headline-making, historical "firsts." Some of these firsts included the first satellite, the first robotic spacecraft to the Moon, the first man in space, the first woman in space, and the first spacewalk. To the chagrin of the United States, each of these early f .....
