"The Multiple Sides of Computer Science" by Matthew Minerd (2014)

It often takes some time for a new discipline to become recognized as an independent science. An excellent example of this is computer science. In many ways, this science still is a hodgepodge of several different sciences, each one having its own distinct character. For example, some computer scientists are almost indistinguishable from mathematicians. Many of the most difficult topics in pattern recognition and data communications require intensive mathematics in order to provide software solutions. Years of training in the appropriate disciplines are necessary before the computer scientist can even begin to work as a programmer in such areas. In contrast to those computer scientists who work with complex mathematics, many computer scientists work on areas of hardware development that are similar to disciplines like electrical engineering and physics.

However, computer science has its own particular problems regarding the unity of its subject matter. There are many practical applications for computing work; therefore, many computer scientists focus on learning a large set of skills in programming languages, development environments, and even information technology. All of these disciplines have a certain practical coloration that is quite distinct from the theoretical concepts used in other parts of the field. Nevertheless, these practical topics add to the broad range of topics covered by most academic programs that claim to focus on “computer science.” It can only be hoped that these disciplines will increase in orderliness in the coming decades.

What will be the effect of increased orderliness in computer science studies?

"Comparing Technologies: A Difficult Endeavor" by Matthew Minerd (2014)

Comparisons of technology are often difficult to make, not only because of the rapid pace of improvements but also because of the many new applications that are available as time progresses. If we were to consider the contemporary graphing calculator and the calculation capacities of computing machines from fifty years ago, there would be astounding improvements between these two devices. However, the improvements are not reduced merely to speed improvements. A graphing calculator also has numerous output capacities that far exceed those available much older computers, none of which had the ability to represent their output in any manner even closely resembling that of contemporary devices. Merely consider the display capacities of such a device. These enable users to input many new kinds of information, enabling design engineers to design new hardware functions to match the new means of collecting user input.

The situation is even more obvious when one considers the numerous functions performed by a modern “smartphone.” These devices are equipped with a panoply of features.  With all of these new functions come many new types of computational capabilities as well. In order to process images quickly, specialized hardware must be designed and software written for it in order to ensure that there are few issues with the phone’s operation. Indeed, the whole “real time” nature of telecommunications has exerted numerous pressures on the designers of computing devices. Layers of complexity, at all levels of production and development, are required to ensure that the phone can function in a synchronous manner. Gone are the days of asynchronous processing, when the computer user entered data into a mainframe, only to wait for a period of time before the processing results were provided. Today, even the smallest of digital devices must provide seamless service for users. The effects of this requirement are almost beyond number.

What is the effect of the features found on modern “smartphones”?

"The Holy Roman Empire" by Daniel Morrison (2014)

The Holy Roman Empire was somewhat unique among the various organized states of Middle and Early Modern Europe in that the Emperor was chosen by a group of electors. This is in stark contrast to the strict hereditary nature of English or French succession, where the position of monarch was handed down from the outgoing ruler to his closest legitimate heir, usually a son. In the Holy Roman Empire, the Emperor was chosen by seven electors, which in theory might seem to give the Empire a sort of early democratic flavor. However, in practice, only two or three families were ever able to draw on sufficient personal wealth to stand for election. Of these, the Luxembourgs and the Hapsburgs are most well known. The Hapsburgs were so successful that they were able to maintain their “elected” position for almost four centuries, and the Luxembourgs somehow still have a small country named after their family almost seven hundred years after their fall from dominance.

Why were the Hapsburg and Luxembourg families able to stand for election?

Passage adapted from H.G Wells's Anticipations (1901)

Democracy of the modern type—manhood suffrage and so forth—became a conspicuous phenomenon in the world only in the closing decades of the eighteenth century. Its genesis is so intimately connected with the first expansion of the productive element in the State, through mechanism and a co-operative organization, as to point at once to a causative connection. The more closely one looks into the social and political life of the eighteenth century the more plausible becomes this view. New and potentially influential social factors had begun to appear—the organizing manufacturer, the intelligent worker, the skilled tenant, and the urban abyss, and the traditions of the old land-owning non-progressive aristocratic monarchy that prevailed in Christendom, rendered it incapable—without some destructive shock or convulsion—of any re-organization to incorporate or control these new factors. In the case of the British Empire an additional stress was created by the incapacity of the formal government to assimilate the developing civilization of the American colonies. Everywhere there were new elements, not as yet clearly analyzed or defined, arising as mechanism arose; everywhere the old traditional government and social system, defined and analyzed all too well, appeared increasingly obstructive, irrational, and feeble in its attempts to include and direct these new powers.

But now comes a point to which I am inclined to attach very great importance. The new powers were as yet shapeless. It was not the conflict of a new organization with the old. It was the preliminary dwarfing and deliquescence of the mature old beside the embryonic mass of the new. It was impossible then—it is, I believe, only beginning to be possible now—to estimate the proportions, possibilities, and inter-relations of the new social orders out of which a social organization has still to be built in the coming years. No formula of definite reconstruction had been evolved, or has even been evolved yet, after a hundred years. And these swelling inchoate new powers, whose very birth condition was the crippling, modification, or destruction of the old order, were almost forced to formulate their proceedings for a time, therefore, in general affirmative propositions that were really in effect not affirmative propositions at all, but propositions of repudiation and denial. "These kings and nobles and people privileged in relation to obsolescent functions cannot manage our affairs"—that was evident enough, that was the really essential question at that time, and since no other effectual substitute appeared ready made, the working doctrine of the infallible judgment of humanity in the gross, as distinguished from the quite indisputable incapacity of sample individuals, became, in spite of its inherent absurdity, a convenient and acceptable working hypothesis.

According to the author, what was the major reason for the British Empire taking part in the democratization of the period in discussion?

Adapted from Ten Great Events in History by James Johonnot (1887)

Following the Council of Clermont, preparations for invading the Holy Land began in almost every country of Europe. The nobles mortgaged their estates, the farmer endeavored to sell his plow, and the artisan his tools to purchase a sword. During the spring and summer of 1096, the roads teemed with crusaders, all hastening to the towns and villages appointed as the rendezvous of the district. Very few knew where Jerusalem was. Some thought it fifty thousand miles away, and others imagined it but a month's journey; while at the sight of every tower or castle the children exclaimed "Is that Jerusalem?" 

Little attempt at any organization was made, though the multitude had three leaders. It is said that the first band, consisting of twenty thousand foot, with only eight horsemen, were led by a Burgundian gentleman called Walter the Penniless. They were followed by a rabble of forty thousand men, women, and children led by Peter the Hermit. Next followed a band of fifteen thousand men, mostly Germans, under a priest named Gottschalk.

Like their nominal leader, each of the followers of Walter the Penniless was poor to penury, and trusted for subsistence to the chances of the road. In Hungary, they met with loud resistance from the people, whose houses they attacked and plundered, but in Bulgaria, the natives declared war against the hungry horde; they were dispersed and almost exterminated. Some, including Walter, reached Constantinople, where they awaited Peter and his companions. The Hermit, who had the same difficulties to contend with in marching through Hungary and Bulgaria, reached Constantinople with his army greatly reduced, and in a most deplorable condition. Here he and Walter joined forces. They were hospitably received by the emperor, but their riotous conduct soon wearied out his patience, and he was glad to listen to a proposal to help them at once pass into Asia. 

The rabble accordingly crossed the Bosphorus, and took up their quarters in Bethynia. Here they became perfectly ungovernable, ravaging the country around, and committing incredible excesses; at length Peter, utterly disgusted and despairing, left them to their own guidance and returned to Constantinople. The bravest of them were annihilated in a battle fought near Nice, Walter the Penniless falling with seven mortal wounds. Between two and three thousand alone escaped. The emperor dismissed them, with orders to return home, and thus ended the disastrous expedition of Walter the Penniless and Peter the Hermit.

The fifteen thousand Germans led by Gottschalk never reached Constantinople, being slaughtered or dispersed during their passage through Hungary. Thus, within a few months, upward of a quarter of a million of human beings were swept out of existence. And they had spent their lives, without one important result having been accomplished. This was the worst paroxysm of the madness of Europe.

Can we infer is the main reason for the failure of the first crusades described in the passage, according to the author?

What problems did the early crusades described in the passage cause those living in Hungary and Bulgaria?

Adapted from Scientific American Supplement No. 1082 Vol. XLII (September 26th, 1896)

The rowboat Fox, of the port of New York, manned by George Harbo, thirty-one years of age, captain of a merchantman, and Frank Samuelson, twenty-six years of age, left New York for Havre on the sixth of June. Ten days later the boat was met by the German transatlantic steamer Fürst Bismarck proceeding from Cherbourg to New York. On the eighth, ninth and tenth of July, the Fox was cast by a tempest upon the reefs of Newfoundland. The two men jumped into the sea, and thanks to the watertight compartments provided with air chambers fore and aft, it was possible for them to right the boat; but the unfortunates lost their provisions and their supply of drinking water. On the fifteenth they met the Norwegian three-masted vessel Cito, which supplied them with food and water. The captains of the vessels met with signed the log book and testified that the boat had neither sail nor rudder. The Fox reached the Scilly Islands on the first of August, having at this date been on the ocean fifty-five days. It arrived at Havre on the seventh of August.

Cost what it might, the men were bent upon reaching this port in order to gain the reward promised by Mr. Fox, of the Police Gazette. Thanks to the wind and a favorable current, they made one hundred and twenty-five miles in twenty-four hours. One slept three hours while the other rowed. Their skins and faces were tumefied by the wind, salt water, and sun; the skin of their hands was renewed three times; their legs were weakened; and they were worn out.

Why did the two men want to row across the Atlantic?

"A Short History of Recent Zoos" by Will Floyd

Throughout the twentieth century, zoos underwent large-scale transformations. Before World War I, zoos were small parts of larger municipal parks, and featured sparse cages with little room for their inhabitants. This model held sway until mid-century, with many zoos struggling to remain open during the Great Depression and World War II. The successful zoos survived through making themselves cheap family entertainment. In the 1960s, zoos began to change in drastic ways. With the growing strength of environmental and animal rights movements, the public clamored for more naturalistic and spacious environments in which the animals could live.

The most emblematic of these transformations was the development of the Los Angeles Zoo. In 1966, the cramped and antiquated zoo used grants from the city government to move to a brand-new facility. Although the zoo moved just two miles away, the new location was exponentially bigger, and it featured fresh landscapes that resembled the animals’ natural habitats, instead of dilapidated cages. As the Los Angeles Zoo developed, it was able to work on preservation and conservation efforts for endangered species. New educational programs also became key elements of the Zoo’s mission. Now the old Zoo’s cages stand as ruins and reminders of what past generations saw when they visited years ago.

The author would suggest a new zoo should __________.

Adapted from "Wild Animals in Captivity" by W. A. Atkinson in Chatterbox Periodical (1906, ed. J. Erskine Clark)

Notwithstanding all the care which is now bestowed upon wild animals in our zoological gardens and menageries, nearly all of them suffer a little in some way or other by confinement. When we think of the great difference which exists between the surroundings natural to a free wild animal, and those of even the best zoological gardens, we cannot but be surprised that so many animals from all parts of the world can be kept alive and in good condition in a climate so changeable as ours. Every effort is made by the keepers to copy as far as possible the natural conditions to which each animal is accustomed.

It was usual, for instance, to deprive all the flesh-eating animals of one of the greatest traveling menageries of food during one day in each week. It was found by experience that the animals were healthier when they suffered periods of fasting like this, than they were when they were fed regularly every day without a break. The explanation of this was very simple. These animals, when they were living wild in the jungles, forests, deserts, or ice-fields, obtained all their food by hunting. When game was scarce or difficult to catch, they were compelled to go hungry; and this occurred so often as to be a natural condition to which they were well accustomed. When, therefore, they were placed in cages, and were fed as regularly, though not as frequently as human beings, their health was more or less impaired.

Animals in confinement often undergo slight changes even when no alteration in their appearance or falling-off in health is noticeable. Many of them, for instance, rarely have young ones, and even when they have, the young are seldom as healthy and robust as if born in a wild state. The keepers have frequently the utmost difficulty in rearing animals which are born in menageries and zoological gardens. Yet if these animals were born in their own countries and under natural conditions, they would grow up healthy and strong, without receiving any more care than a kitten receives from its mother.

An incident which occurred in the Zoo not long ago affords a striking illustration of these facts. A wolf had an ordinary family of eight young ones. The keepers, probably thinking that these were too many for the captive wolf to bring up alone, divided the family. Four of them were left with their mother, and four of them were placed in charge of a collie. The dog took kindly to her foster-children, and reared them successfully with her own. This was only what the keepers expected. But when they placed the young ones together again, and compared the collie's family with the wolf's family, they were surprised to find that the four which had been nurtured by the collie were stronger and better animals than their four brothers and sisters. The best explanation of this result is that the collie was living a healthy natural life, while the wolf, though to all appearance quite well, was not enjoying the full vigor which results from a free and active life.

Why did the dog have greater success raising the wolf pups than the wolf pups' mother?

"The Meaning of 'Liberal Arts Education'" by Matthew Minerd (2013)

Many people use the expression “liberal arts education” but do not know much at all about the original meaning of such an education. It is often thought that a “true liberal education” is one that gives the student knowledge that is not pursued for “utilitarian values”—that is, knowledge that is not merely “for the sake of getting a job.” Sometimes, the expression “liberal education” is used to describe an education that is not a mere repetition of old beliefs, but is open-minded and “liberal” in this way.

To understand the original meaning of the expression “liberal arts” it is necessary to consider each part of the expression as it was used in its ancient and medieval senses. The word “liberal” was used to describe these “arts” insofar as they were not the “servile arts,” that is, “arts” in the sense of “artisan work.” In this regard, “liberal arts” were not a matter of “getting a job.” The word “art” still had a meaning that was related to “artisanship.” However, these “arts” were “liberal” because they were the “arts of reasoning,” that is, “the arts of the mind.” They were meant to be tools that prepared someone for more in-depth studies. Thus, they were not envisioned as “knowledge for the sake of knowledge.” Instead, they were the initial tools that enabled the young student to reason properly.  This more ancient sense of the “liberal arts” is often missed or, at least, partially overlooked in contemporary discussions about them.

According to the reasoning of the passage, which sentence directly explains the older meaning of “art” in the expression “liberal arts”?
