Albert Einstein: The Theory of Relativity.

In his lifetime, Einstein discovered, formulated and theorized many solutions to problems related to physics.  Solutions to some of these problems were known as:  The theory of Relativity;  Wave-Particle-Duality; Quantum theory; and Statistical Mechanics.

     In 1907, by using his applications of special relativity, Albert Einstein discovered that E=MC  .   In the equation, E=MC , E represented energy, M the mass, and C the speed of light.  This discovery (E=MC ) would revolutionize the study of physics and change the conventional thinking of the relation between the speed of light, mass, and energy. 
     More than half a century later, this simple formula would alter the course of human history, by ending world war II, with the explosion of atomic bombs above Hiroshima and Nagasaki.  The atomic bomb was the practical application of Einstein's theory of Relativity.  Little did Einstein know when he was a young physicist, that his theory of relativity would fifty years later bring the dawn of the nuclear age.                   

     Einstein's theory of relativity changed the thinking regarding some basics theories of physics.  Prior to this theory of relativity no one understood that energy  was the product of the mass times the speed of light squared.  Prior to Einstein's discovery, there was no theory showing how, energy, the speed of light, and mass, all relate to each other.  Conventional wisdom stated that the atom and the nucleus of the atom was an indivisible unit.  No one dreamed that splitting an atom of matter could unleash such a tremendous force of energy.  However, in the nineteenth century (1862), James Maxwell wrote the equations of Michael Faraday's theory, that light (energy) consisted of an electric field traveling at right angles to a magnetic field.  In fact, it was upon this "field concept" that Einstein later drew the basis for his Theory of Relativity.[1]
     On July 12, 1887, Albert Michelson and Edward Morley took measurements of the data from their experiment testing their theory on ethers.(Ethers were thought to fill all space and penetrate all matter.)  Many scientists in the world were very curious as to what the outcome of the experiment would bring.  The Michelson-Morley experiment failed.  Two perpendicular light beams sent through mirrors and telescopes took the exact same amount time to make their respective round trips.  Through the failure of the experiment, Michelson and Morley were unable to detect an ether.[2]




     Over the last sixty years there have been numerous applications of Einstein's theory.  The two most striking results
have been the development of atomic and hydrogen bombs, and nuclear power stations.
     Up until several years ago, the fate of the world was controlled by the two superpowers of the U.S. and the U.S.S.R., each with vast quantities of nuclear war-heads aimed at each other.  The political balance between was maintained by the fear of each other's nuclear bombs.
     The other major influence affects us all in a more positive manner.  Here in Thornhill, part of our electrical energy that we consume every day is produced by Ontario Hydro Nuclear reactor stations.  In a country like France, more than half of their electricity needs are provided by nuclear energy.                                       
     Einstein's theory of relativity opened whole new spectrum of thinking for scientists around the world. 
     In 1924, a young Indian physicist, S.N. Bose, set froth a theory in which radiation was treated as a gas of light quanta.   Einstein applied Bose's new statistical idea to develop an analogous theory for an ideal gas of material particles.
     In the same year of Bose's theory, Louis de Broglie wrote a thesis on the parallel between the gas of particles and the gas of light quanta.  This thesis was brought on by using the theory of relativity as the basis of thinking.  This thesis in turn, inspired Einstein to successfully prove the wave-particle duality in 1926.[3]

     Einstein was the copernicus of the twentieth century.  No scientist before or after the life of Einstein has been able to equal his accomplishments.  No other scientist has inspired the world both politically and scientifically so much, influencing the minds of scientists and human beings abroad.  Einstein worked many hours trying to prove the wave-particle duality and quantum physics, however Einstein will forever be known as the mastermind creator of the equation E = MC , or better known as the theory of relativity.

ON RWANDA

                           ON RWANDA
    
     Basil Davidson's essay "On Rwanda" describes in detail, the 
facts surrounding the colonial history of Rwanda.  It begins with the Belgian colonialism of Rwanda in the mid 1800's, and it ends with the present day tribal warfare between the two main Rwandan tribes.
     Davidson supports his conclusions by using three main arguments.  Firstly, he argues that Rwanda is one of two countries in Africa that colonialism could have left untouched.  Secondly, the Banyouwanda monarchy, which was introduced by the Germans in 1907, is cited as the main reason for creating the hatred which still exists between the two tribes of Rwanda.  Lastly, Davidson concludes at the end of his essay, that Western nations should learn from their mistakes in their colonialism of Africa.  Davidson claims that the Western nations should allow "the people concerned, nationally or regionally" "to devise and apply their own remedies and solutions" to their respective problems.
     Many of Davidson's arguments are supported by historical data which persuades the reader to believe in his conclusions.  More over, by doing this, the reader is able to understand the significance of the argument.  A good illustration of this method, appears around Davidson's second argument about the Banyouwanda monarchy.  Before providing his argument, Davidson describes the respective roles of the two main tribes of Rwanda at the time of colonialism.  He furthers this by illustrating facts and details to support his argument.  For example, he describes the tribes' co-habitation patterns and its eventual disintegration. 
     Through his constant use of metaphors, Davidson allows the reader to better understand his essay.  For the metaphors provide imagery that one can relate to.  Moreover, metaphors are used at the beginning of his essay, thus giving foresight of what the paper is about.  The first sentence of the essay reads:  "Africa tramples in its misery and blood,..."  Another metaphor soon follows:  "No minerals worth a row of beans.  Not - it seems - so much a sniff of oil."  A certain tone has been set, angry, yet concerned. 
     The main body of Davidson's essay tells the history of the co-existence of the two main tribes:  The Hutus(80% of the population); and the Tutsis(15%).  The Tutsis are considered by the Germans as the 'ruling class', because they are the cattle-drivers of Rwanda.  The Hutus are considered the middle and lower class of Rwanda, for they are simply involved in banana production.  Since the Tutsis were considered the 'ruling class', they provided the armed forces needed by the colonials.  Davidson uses another metaphor to have the reader understand this implication:  "These Banyouwanda Monarchs were no more divine in status than Englands's Plantagnet kings, but also no less, being the recognised apex of those powers which belonged to the eternal."   A clear separation of two tribes and societies is created by the metaphors and facts which Davidson lays out.

     Davidson's method of writing is very persuasive.  Whether knowledgeable or not, a reader of this essay develops a clear understanding of the issues surrounding the war-torn Rwanda.  The use of metaphors and his somewhat cynical view of colonialism further strengthens his argument.  Moreover, Davidson's three main arguments are clearly laid out and are easy to understand.  The use of many facts and details make Davidson's arguments very credible.

The Allende government

BY FH in 1995 
   


  On september the 11th, 1973, general Augusta Pinochet

directed a military coup which overthrew President Allende and

his government.  For the 3 years leading up to the coup,

Allende's government took many steps to establish Chile as a

socialist nation.  The Allende government nationalized major

copper mines, took over many of Chile's remaining private

industries and banks, and made numerous land expropriations and

collectivizations.

"By 1973, most domestic production had declined, and
    
severe shortages of consumer goods, food, and manufac-   

tured products were widespread.  There were mass demon-

strations against the government, recurring strikes,

violence by both government supporters and opponents,  

and widespread rural unrest.  Chilean society became

polarized into hostile camps."1
Many of Chile's middle-class citizens were upset at the Allende government, leaving the door open for Pinochet's Coup d'etat.  Through both economic and social reforms, Pinochet's military government brought Chile from economic hardship to economic prosperity.  There has been much argument among Chilean critics as to the positive and negative implications of these reforms.  The purpose of this paper is to focus on those reforms which affected GNP Per Capita, infant mortality rates, and income distribution.  These reforms include:  open-market orientation; decentralization and privatization of social policies; and relocation policies.

     GNP per capita measures the amount of domestic and foreign economic output per person of the respective economy.  In order for GNP per capita to increase, the growth rate of GNP must be higher than the growth rate of the population.  GNP per capita is a common indicator of a population's standard of living.
     The infant mortality rate is the annual number of deaths of infants under the age of 1 per 1,000 live births.1  The lower this number is, the better.  In order to decrease infant mortality, a country must increase education standards, and  specifically health standards.  Purified drinking water, proper raw sewage disposal, and immunization practices are the most common methods used to minimize infant mortality rates in developing countries.
     Income distribution over time shows which income group the growth(if any at all) in the economy is actually reaching.  Income groups are typically separated into quintiles.  An increase in income in the top quintile indicates that the rich are getting richer, and that the poor or middle class are getting poorer.

     In the period of 1970 to 1975, Chile's GNP per capita grew at an average pace of only 1%.  In the period of 1980 to 1985, Chile's GNP per capita grew at an average pace of only 0.6%.2  During this period, the population growth rate average between 1.6 and 1.7%.  Quite obviously, it is the economy of Chile during this period which is the cause of concern for the GNP per capita variable.
     The low GNP per capita(see figure 1) was caused by two periods in Chile's military regime(1973-1990).  The first such period occurred in 1973-1975.  In 1973, Chile endured an inflation rate of 500%!  In 1975, after enduring 2 years of high inflation rates and low GNP growth, Pinochet invited a group of economists trained at the University of Chicago('The Chicago Boys') to Chile.  These economists created a free-market economy by taking many drastic steps.
"Most markets were freed from government controls, and prices were allowed to float.  The peso was devalued, permitting an increase in non-traditional exports.  Tariffs were reduced in stages to a uniform level of 10%.  Under this free market policy, from 1976 to 1981, GNP increased in real terms by an annual average of more than 7%."3


    
     The annual average inflation was reduced to 9.9%, in 1982.4  Unfortunately, a heavy price was paid for the drastic action taken by the "Chicago Boys" (from 1976-1981) as the unemployment reached 20% in the mid to late 1970's.  By 1989, the effects of freeing up Chile's economy were still being felt.  "In 1989, the last year of Pinochet's rule, real wages were still only 90.8% of what they had been in the 1970 base year."5  The decrease in wages is quite dramatic.  Since there was an increase in real GNP per capita for Chile, a rise in real wages would be an obvious outcome.  If the increase in GNP did not reach the worker in real wage increases, than who did it reach?  This question will be answered when the essay focuses on the income distribution in Chile.
     As for "The Chicago Boys", their main goal was met:  To free Chile's economy for trade with any nation for any good or service.  The economists also compelled Chile to create new goods and services, in order not to rely on the income created from Chile's main export:  Copper.  As world demand decreased, demand for copper diminished as well.  "The  Chicago Boys"  were right, but unfortunately, the government of Chile had not reacted hastily enough.  For in 1982 and 1983, real GNP fell by 17% and 14% respectively!6  The decline in real GNP was due primarily to the decline in the prices of copper. During these two years, Chile accounted for the biggest decline in real GNP in Latin America.  Fortunately, Chile also experienced the biggest increase in real GNP, averaging 6%, from 1984 to 1991.

     As of 1994, Chile's IMR(infant mortality rate), except for Costa Rica's, is the lowest among all Latin American countries.  In twenty years, Chile's IMR went from as high as 44.0 in 1973, to as low as 13.9 in 1994.(see figure 2)  The favourable reduction in the IMR rate was due principally to "the outcome of public efforts to provide care for mothers and children, including nutrition programs for nursing children; in addition to this, the educational level of mothers was steadily rising, and there was a drop in the number of births."7
     Upon taking power in 1973, Pinochet's government cut many government social services "to the bone."  The government cuts had a large impact on social security, housing, and health care.  The government established a program of decentralization and privatization of social programs.  Social security and health care were privatized, and shantytowns were torn down as new low-income housing were built in favor of improved housing(although improved housing was not always the case.)
     Another part of the government program was to increase emphasis on the 'extreme poor'.  The main instrument developed to target the poor was the Ficha Cas.  The Ficha Cas was first developed in 1979.  The basic idea was that poverty produced certain symptoms, and by observing these symptoms, the government could make transfers to what the Ficha Cas found to be the 'extreme poor'.  A test was developed, and a typical person or family would either pass or fail.  If someone passed, a subsidy would be given, if they failed, they would not receive anything from the government.  The Ficha Cas was developed by the "Chicago Boys".  These economists were technocrats.  Therefore, if a family failed the 'poverty test' by even one point, they were denied access to the transfer payments.  Where the government drew the line on excluding or including someone depended on the amount of resources allocated for transfer payments to the poor that year.
     On a positive note, the Ficha Cas targeted citizens who were at the bottom end of the scale with respect to nutrition, clothing, housing, and health care.  Most of the resources of the Ficha Cas focused on the weak citizens:  Senior citizens  and young infants.  The payment plans towards these two groups were known as:  Subsidio Unico Familiar (SUF), a child benefit; and the Pension Asistencial (PASIS), a disability and limited old age pension.  The targeting of young infants was a large factor in the decrease of the IMR between 1973 and 1994.
     The Chilean government also used another method to target the 'extreme poor' and the mortality rate.  They had a reallocation of resources administered to lower levels of the population by reducing the benefits for the middle class families.
"...during the 1980's, targeting helped radically improve the nutritional situation of infants and children under five years of age - the most notable success area - and probably contributed to some other improvements, such as greater availability of household equipment among poor families.  More indirectly, sewerage and water systems in poor areas also showed substantial improvement."8



Through the disparities of human rights abuses, diminishing GNP per capita and government cuts in many, but not all social services, the decline of Chile's infant mortality rate was quite remarkable.

During the mid 1970's, Pinochet's government undertook  a policy of decentralizing and relocating social assistance.  Part of this policy included a reform for the resettlement of inadequately housed people of Chile's shantytowns.  This reform was also part of the new policy to target the 'extreme poor'.  It involved the creation of new urban developments on the outskirts of existing townships.  These townships held basic infrastructure and housing, but little else existed in terms of cultivation of food or employment.  These houses were often improvements over the previous shantytowns.  However with no community facilities within the vicinity of the townships, these developments often created near-homogeneous poverty and socio-cultural deprivation.
     Not only did many people of this "shake-up policy" endure the stagflation of the early 70's and 80's,  but any jobs which they had had in the shantytowns, had now disappeared in their new-built developments.  When these townships were turned into municipalities, many of these towns were ill-equipped to handle the responsibilities given to them by the Chilean federal government.  As much as this program was supposed to be make local governing more efficient and decrease 'extreme poverty', it accomplished the exact opposite of that.
     The most disturbing fact is perhaps the widening of the income distribution(see Figure 3) which was a direct result of this shake-up policy.  During the first two years of Pinochet's government, real wages fell to 62% of their 1970 levels.  In the last year of Pinochet's rule, 1989, real wages were still only 90.8% of what they were in 1970(nearly 20 years!)  As depicted by Figure 3, income distribution became more concentrated in the top 10% of  the population.  "A study conducted in Greater Santiago in the late 1980's noted that poverty had increased drastically, from 28.5% in 1969 to 49% in 1987."9
     In 1970, 60% of the social security payments were made by the government, while the remaining were made by employers and/or the workers.  After the coup, the military government had hoped to rid of the responsibility of social security completely.  As well, the government persisted that the employer no longer had to contribute to the workers' pension.  Much of the social security system became privatized.  Nonetheless, there was a transition period where both systems would remain in force.  The workers already on the old system could elect to remain on it, while the government would still be responsible for maintaining the mandated pension levels. The two largest financial conglomerates took control within months of privatization.  After the 1981-1982 recession, transnationals took control, at which point the system became even more undercapitalized.
     The nature of decentralization included creating municipalities in order to localize many of the services the federal government was providing.  These municipalities were given a certain amount resources from the Chilean government.  Unfortunately, the federal government did not reallocate resources according to need or wealth.  Instead, many rich areas of Chile such as Santiago, Providencia, and Las Condes (with only 21% of the population), accounted for 56.8% of all municipal investment in the period of 1980-1984.  In poor townships such as La Florida(pop: 191,800), "residents had to fight to gain permission to build a one-room wooden day-care centre, staffed half of the day by local women."10
     The health care system underwent reforms similar to social security.  The reforms privatized much of the health field.  The newly-formed companies were called ISTAPRES.  One of the major differences between the two systems is that under the old system a worker contributed 6% of his salary and, in return, received whatever medical attention was necessary.  However under ISTAPRES, medical coverage improved according to the amount contributed.  This system became highly elitist, as the quality of medical coverage depended on the individual's ability to pay.  Not surprisingly, most of the lower paid workers stayed with the state system(FNS)  The cost included a surcharge of 25% to 50% of the medical cost.

     Perhaps the most ironic fact of the Pinochet government from 1973 to 1990 was the lack of planning in their policies.  The main reason for the toppling of the Allende government was its communist outlook.  Communism was known to be  bureaucratic, inefficient and unrealistically idealist.  However when looking at the policies of the Pinochet government it is difficult to argue that their policies were nor idealistic, nor inefficient.  The "Chicago Boys" used a theory on Chile, however theories are not always, nor are they realistic.  In this case, the pure free-market economy was only an ideal.  Chile suffered in many ways more than one.  A very volatile economy, negative real wage growth, and a widening gap of income distribution and social services(such as social security, and health care)  A lack of planning allowed the Chilean government to waste money on reforms such as 'the shake-up policy', where conditions for the poor grew only worse.  After completing many hours of research it is quite remarkable to see that Chile was to decrease its IMR to such level, when at the same time, poverty has grown among the poor so much.
