Fusion Energy
.... override their repulsion is through enormous heat,
this method is called thermonuclear.
Even though fusion reasearch still needs a lot of time, there has been
some progress in discovering how we can use this. The two fusion reactions
that are the most promising both involve the heavier isotopes of hydrogen:
1) deuterium (composed of one proton and one neutron) Deuterium occurs
naturally as a minor constituent in all hydrogen-containing materials--such
as water--in quantities sufficient to meet all .....

Geneticists
.... success
may be above $54,000 a year. Benefits usually include pension plans, health
insurance, and paid holidays and/or vacations.
The employment outlook is very good. Some, highly trained geneticists
can open their own firms. This is probably because of a recognition that
mutations may be able to strengthen our immune systems, raise our endurance,
or even other things not thought possible.
Most geneticists work in clean laboratories and work between thirty
five and forty hours a week. They .....

Hereditary
.... ever live up to your potential.
Traits such as what you look like are inherited from your parents.
Your potential is also inherited from your parents. Chromosomes contain the
information of a person's potential height, potential strength against
disease, and other physical characteristics.
A human being has 23 pairs of chromosomes in every cell in his or her
body (except reproductive cells). If, during a stage of growth, a fetus
somehow loses one of these chromosomes, the baby may die, or have .....

Mimicry In Nature
.... spend their time
masquerading as others. So clever are their disguises that you've probably
never known you were being fooled by spiders impersonating ants, squirrels
that look like shrews, worms copying sea anemones, and roaches imitating
ladybugs. There are even animals that look like themselves, which can also
be a form of impersonation.
The phenomenon of mimicry, as it's called by biologists, was first
noted in the mid-1800s by an English naturalist, Henry W. Bates. Watching
butterflies in the fo .....

named. Experiment 3 showed the same results as the previous two
experiments. The fourth experiment, with the introduction 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

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

The Purpose of this experiment is to determine what type of stimulus
information is more easily remembered, be it in randomized manner or
meaningful. When are more errors made in remembering the stimuli, among
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-sub .....

The Laser
.... laser had everyone excited.
The laser was put through many tests and experiments to see what it
could do to help modern civilization. At first there weren't many uses for
the laser. Then in 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 a .....

Light: A Fundamental Force In Our World
.... these
characteristics are found in waves of any type, from radio frequency waves,
up to Gamma and X- rays. Light, however, also exhibits qualities
characteristic of particles such as neutrons and protons. 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 .....

between one hundred eighty and two hundred fifty kelvins. Finally, the
thermosphere is the final level in the atmosphere. It's range is eighty-
five to one hundred forty kilometers and also temperatures as high as four
hundred sixty kelvins.

The setup is the following: Purpose: Restrict phosphates to aluminum
phosphates for 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 proce .....

Plant Breeding
.... the hybrid variety, yielding
twice as much corn.
Plant breeders have a definite advantage over animal breeders, because
they can often produce fertile varieties - indeed, new species - by
crossbreeding 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 .....

The Rain Forest - Example Of A Flourishing Ecosystem
.... This soil contains few nutrients, which is why attempting to grow
any sort of crops would be futile. On top of this soil is a thin layer of
humus, which simply said is the compost made from the millions 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

Discoveries Of Scientists Of The "Age Of Reason"

theory.
After Copernicus's death there were three other scientists which
helped credit the Heliocentric theory. Tycho Brahe was the first, he
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 ev .....
