The Stroop Phenomenon
.... of less common
objects, subjects could name the words faster than generating a category
name for the words. Naming pictures are prone to interference when
incongruent words are presented simultaneously. Word naming is not as much
influenced by distracting pictures. Pictures and words differ in the
amount of information to be filtered out, to get the correct response.
The design of this experiment is a within subject experiment as the
number of choices to be made after viewing the stimulus on the screen are
same for everybody (2,3,4). Also the meaning versus number choices (same,
different, conflicting) are used by eve .....

Lab: Determining What Type Of Stimulus Info Is More Easily Remembered

these two types of stimuli used (CVC). Also, when a correct response is
given, which was the type of stimuli (CVC) that caused this to occur.
The design of this experiment on verbal learning has both within-
subject and between-subject variables. The within-subject variables are
the words (CVC) that are stored in the computer which are the default words
to be used. The between-subject variables are the number of stimuli used
and the choice of the stimuli using the experimenters own words (CVC). The
independent variable for this lab is the number of stimuli presented and
the type of .....

The Laser
.... the 1970's it became very important. It was finally
being used in everyday life. As years went on the uses grew in number.
Today lasers were being used in a variety of ways. This includes
entertainment, military, communication, businesses, measurement, cutting,
and more.
Measurement: Lasers have become an important part of measurement. A laser
is the fastest way to measure long distances. This use can be applied in
construction work and astronomy.
Cutting: A laser is also great for cutting objects. It can get to those
hard to reach places by the use of mirrors to bend the beam of light. It
also is strong enough to cut t .....

Light: A Fundamental Force In Our World
.... A photon, or
quanta, is the "packet" of energy that is sent in a light wave. Like a
particle, the photon is believed to have a finite mass, and has the ability
to affect other matter. As light strikes a photovoltaic solar cell, it
knocks electrons in the silicon atoms on the surface into a higher state of
energy. When these return to their normal, or "ground" state, energy is
produced in the form of electricity. Thus, light is termed a "wave-
particle," and this property is called the "wave-particle duality of
nature." Many questions concerning what makes up light still lie unanswered,
but this much is thought to be true.

hundred sixty kelvins.
Society has been widely addressed with the many problems that we are
having in our environment today. A major problem is that of CFCs. CFC
stands for Chlorofluorocarbons which are found in many of the aerosol spray
cans. In December of 1973, Rowland and Molina discovered that CFCs can
destroy the ozone in the stratosphere.
In June 1975, the Natural Resources Defence Council (NRDC) sued the .....

Phosphorus: Chemical Reactions Of Phosphorus And Its Importance
.... easier disposal of phosphorus.
The first step in phosphorus removal is the Rapid Mix. In this stage,
alum and waste or water runoff(known as effluent) is blended together as
rapidly as possible with the use of a high-speed mixer called a "flash
mixer." After this instant mixing, a slower moving process called
coagulation and flocculation follows to allow the formation of a floc.
These processes occur in a Flocculation Chamber. This floc consists of
suspended and colloidal matter, mainly including the aluminum phosphate.
Next, the effluent travels to a clarifier in which sedimentation occurs.
The heavier aluminum phospha .....

Plant Breeding
.... between species. This is because hybrids are often polypoid.
Polyploidy, as we know, can occur naturally in the wild. Some species of
cotton that we grow are polypodies that probably arose originally by
accidental crosses between different species of cotton.
But breeders do not have to rely on accidents. They can attempt to
produce fertile polypodies by crossbreeding between different species. One
early attempt to produce another hybrid species was made in 1927 by the
Russian geneticist G. D. Karpechenko, who crossbred two quite distantly
related species, a radish and a cabbage. Each species has eighteen
chromo .....

The Rain Forest - Example Of A Flourishing Ecosystem
.... of dead
animals and plants of the forest. When things such as leaves and animals
die their remains are quickly broken down by a limitless amount of tiny
organisms. Some insects that do just this sort of thing include: beetles,
ants, termites and a host of others. With all of this death happening so
quickly you would expect a sort of rotten smell to be in the air. This,
however, is not the case. This is simply because everything that is dead in
the forest is broken down so fast. One example of how true this is would be
to kick a fallen tree. Chances are it would crumble to pieces because
termites had chewed, and knawed there wa .....

Discoveries Of Scientists Of The "Age Of Reason"

played with the idea that the planets all revolved around the sun, but the
sun instead revolved around the Earth(still Geocentric). After Brahe's
death Johannes Kepler took the notes and data that Brahe had taken. Kepler
came up with the idea the it would be even more mathematically plausible
that the orbits of the planets around the sun (Heliocentric) were
elliptical, instead of circular and published the book "On the motion of
Mars"-- the problem was unfortunately that this could not be proved. The
most important of these three scientists was Galileo Galilei, whom looked

Reproduction: A Courting To Nature

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
and algae. Generally, these reproduced by splitting into identical copies
of themselves. New generations were thus no better than old ones at
surviving in an altered world. With the emergence of the sexes, however,
youngsters acquired the qualities of two parents. This meant that they
were different from both - different a .....

Could Gambling Save Science: Encouraging An Honest Consensus
.... 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 outlined and the possible advantages are summarized.
THE PROBLEM
THE SCIENTIFIC REVOLUTION Four centuries ago, some Europeans complained
that the existing academic institutions were biased against them. Insiders,
it was said, were "inflated by letters" and shunned anyone who dared
"speculate on anything out of the common way .....
