What message can be received from "Shooting an Elephant"?

Concerning your question about "Shooting An Elephant," I
don't know if "received" is the correct way to think about the ideas presented in the
essay.  If one is precise, a main idea is presented in the essay. 
You can also think in terms of
thesis.

The main idea of the essay is
something like:

The imperialist power is transformed and
corrupted by its imperialism. 

The colonized are not the
only ones damaged by colonization. 

By his/her position of
power, an imperialist is morally corrupted.

The speaker is
made to do things he would not otherwise do.  He not only is forced to kill the elephant
needlessly, but because of the abuse he suffers at the hands of the locals, he actually
develops prejudice and hatred against them.  Because he must maintain his position of
authority, he must behave as he's expected to.  Because he is in an
illigitimate position of authority, he is mistreated by those he is in charge of, and he
responds naturally.

What purpose would Miller have in giving the Crucible a tragic ending?If possible, can you give me specific details in your answer? I understand a...

I think that the choice of a tragic ending was a direct
reflection of the tragedy that was the Salem Witch Trials. Many if the characters in the
play represent actual people who were tried and convicted including the one male
aaccused witch, Giles Cory, who was, in fact, pressed to death. This was a time when
logic and reason did not prevail. For an excellent "real" account of the era, read
Cotton Mather's account of the Trial of Martha Carrier. Mather was a minister, he was
educated, he should have done something to stop the tragedy, but he did not. The reality
wasd that the witch trials brought people back into the folds of the church out of fear
at a time when church attendance was declining. Nothing good at all came out of the
trials, and many innocent people suffered. Nineteen were hanged, Cory was pressed to
death, two people died in prison, and many others spent time in prison for nothing more
than being aaccused of witchcraft, often with no evidence at all (again, look at the
Mather piece and you will see how circumstantial the evidence presented was in the
actual courtroom). I believe that a happy ending would have trivialized the events and
lessened the impact that Miller intended with the piece that serves as not only a social
and historical commentary but also as a warning for future
generations.

Critically analyse the opening scene of Much Ado About Nothing.Act I scene i.

A number of key events are introduced in the opening scene
of this hilarious comedy, which effectively introduces the main characters and some of
the conflicts that will come to dominate the play. Note how Claudio's violence is
foreshadowed by reports of his "feats of a lion." Also, references to the way that
appearances cannot be trusted likewise foreshadow the dark deeds of Don John. Beatrice,
with her strong attack on Benedick, clearly shows herself to be challenging traditional
gender roles, which are characterised in the meek, submissive, and above all silent
Hero. However, the way that Beatrice attacks male arrogance and pretensions equally
foreshadows her somewhat vengeful attack against Claudio in Act IV scene
i.

Note how in this scene the love of Claudio, which is
shown to be somewhat traditional and lacking in originality, is undercut constantly by
Benedick, who continually challenges the romantic speech of Claudio with his own, rather
more irreverent images, for example by saying: "Pick out my eyes with a ballad-maker's
pen, and hang me up at the door of a brother house for the sign of blind Cupid." By the
end of this first scene, Claudio will woo Hero, and Benedick and Beatrice have clearly
engaged in conflict. The constant punning and use of language hints at the major theme
of appearances vs. reality, as we see the way that words are used to yield many
different meanings and can be manipulated by skilled orators, just as others are
manipulated and fooled by the knavery of Don John and Benedick and Beatrice themselves
are fooled into loving each other.

Describe two of the contemporary approaches to psychology.compare how each approach views the cause of behavior.

Existential
Psychology

Existential Psychology is a
contemporary approach that was popularized by Dr. Irvin Yalom. Existential psychology is
based upon the premise that all psychological inquiries can be reduced to man's struggle
with the essential facts of life: the certainty of death, the certainty of loss, and the
sense of utter separateness from fellow man. Existential psychology views all human
behavior as an attempt to deal with these facts. These attempts are called defenses.
Some defenses (i.e. having offspring as a way of extending one's mortality) are
considered healthy. Others (i.e. overeating to escape from one's sense of loss) are
considered unhealthy. Existential psychologists try to help people replace unhealthy
defenses with healthy ones.

Personality
Psychology

Personality psychology views
human behavior as the result of nuanced interaction between an individual's mental,
emotional, and biochemical constitution. Personality psychologists understand behavior
to be the result of these various factors. They may employ terms such as "narcissist,"
"overachiever," or "passive-aggressive personality" when describing an individual's
behavior patterns. Personality psychologist are also interested in the social context of
behavior and may study birth-order, religion, or culture as an aspect of
personality.

What does this scene from "The Birds" suggest about people's relationship with nature? "As the tractor traced its path up and down the western...

I think that a couple of ideas can come out of this
scene.  Of the choices offered, I am more inclined to go with the idea of people attempt
in vain to control nature through technology.  I like this because the concept of
"nature" can be applicable to both the natural world and the birds that are forming
overhead.   The tractor and its inhabitant represent an aspect of consciousness of
supposed strength.  The person can feel a level of power in their being able to subdue
nature for his own benefit.  At the same time, there is a concluding note to the scene
that animals are unafraid of human beings.  To a great extent, the tractor and the
confidence exuded by the man are illusions because the swarming of the natural forces,
the birds, are overwhelming and larger in scope and magnitude that humans and
technological advances.

How is fission different than alpha or beta decay?

In alpha decay a radioactive isotope releases a helium
nucleus with mass of 4 and charge of +2 and a new element, with a lower mass in
produced. Thus, U- 235 if it released an alpha particle would form element 88 (Radium)
with a mass of 231. In beta decay, a radioactive isotope releases an electron which hass
no mass and a charge of -1.  Thus, if Pu-244 decayed by release of a beta particle, a
new element of mass 244 and atomic numer 95 (Americium) would be
formed.

In fission, a uranium nucleus is split by a neutron
into two smaller elements along with the release of additional neutrons and energy.  The
neutrons released can split additional uranium nuclei resulting in a either a controlled
chain reaction (nuclear energy) or an uncontrolled chain reaction (atomic
bomb)

What is meant by the Christian idea of the tri-unity of God?

This idea refers to the concept that God is made up of
three separate beings that are, at the same time, one being.  This is a mystery of faith
-- that of the Trinity.

According to this idea, God is
actually made up of three "persons."   These persons are God the Father, God the Son
(Jesus) and God the Holy Spirit.  Christians believe that these three persons are
separate but that they, nevertheless, make up one God.

This
concept does not make logical sense.  It is impossible to truly understand how three
persons can yet be part of one God.  However, Christians believe that it is true and
that we cannot understand it properly because we are human beings and therefore limited
in our understanding.
