I am engaged in watching a brigade of ants out on foraging duty, and intent on securing for the nest three whole segments of a deceased earthworm. They look for all the world like those busy companies one sees in the Egyptian wall paintings, dragging home a huge granite colossus by sheer force of bone and sinew. Every muscle in their tiny bodies is strained to the utmost as they pry themselves laboriously against the great boulders that strew the path, and that are known to our Brobdingnagian intelligence as grains of sand. Besides the workers themselves, a whole battalion of stragglers runs to and fro upon the broad line that leads to the headquarters of the community. The province of these stragglers, who seem so busy doing nothing, probably consists in keeping communications open, and encouraging the sturdy pullers by occasional relays of fresh workmen. I often wish that I could for a while get inside those tiny brains, and see, or rather smell, the world as ants do. For there can be little doubt that to these brave little carnivores here the universe is chiefly known as a collective bundle of odors, simultaneous or consecutive. As our world is mainly a world of visible objects, theirs, I believe, is mainly a world of olfactible things.

In the head of every one of these little creatures is something that we may fairly call a brain. Of course most insects have no real brains; the nerve-substance in their heads is a mere collection of ill-arranged ganglia, directly connected with their organs of sense. Whatever man may be, an earwig at least is a conscious, or rather a semi-conscious, automaton. He has just a few knots of nerve cells in his little pate, each of which leads straight from his dim eye or his vague ear or his indefinite organs of taste; and his muscles obey the promptings of external sensations without possibility of hesitation or consideration, as mechanically as the valve of a steam engine obeys the governor balls. The poor soul's intellect is wholly deficient, and the senses alone make up all that there is of him, subjectively considered. But it is not so with the highest insects. They have something that truly answers to the real brain of men, apes, and dogs, to the cerebral hemispheres and the cerebellum that are superadded in us mammals upon the simple sense-centers of lower creatures. Besides the eye, with its optic nerve and optic perceptive organs—besides the ear, with its similar mechanism—we mammalian lords of creation have a higher and more genuine brain, that collects and compares the information given to the senses, and sends down the appropriate messages to the muscles accordingly. Now, bees and flies and ants have got much the same sort of arrangement, on a smaller scale, within their tiny heads. On top of the little knots that do duty as nerve centers for their eyes and mouths, stand two stalked bits of nervous matter, whose duty is analogous to that of our own brains. And that is why these three sorts of insects think and reason so much more intellectually than beetles or butterflies, and why the larger part of them have organized their domestic arrangements on such an excellent cooperative plan.

We know well enough what forms the main material of thought with bees and flies, and that is visible objects. For you must think about something if you think at all; and you can hardly imagine a contemplative blow-fly setting itself down to reflect, like a Hindu devotee, on the syllable Om, or on the oneness of existence. Abstract ideas are not likely to play a large part in apian consciousness. A bee has a very perfect eye, and with this eye it can see not only form, but also color, as Sir John Lubbock's experiments have shown us. The information that it gets through its eye, coupled with other ideas derived from touch, smell, and taste, no doubt makes up the main thinkable and knowable universe as it reveals itself to the apian intelligence. To ourselves and to bees alike the world is, on the whole, a colored picture, with the notions of distance and solidity thrown in by touch and muscular effort; but sight undoubtedly plays the first part in forming our total conception of things generally.

Adapted from The Fight at the Pass of Thermopylæ by Charlotte M. Yonge (1876)

The troops sent for this purpose were from different cities, and amounted to about 4,000 who were to keep the pass against two millions. The leader of them was Leonidas, who had newly become one of the two kings of Sparta, the city that above all in Greece trained its sons to be hardy soldiers, dreading death infinitely less than shame. Leonidas had already made up his mind that the expedition would probably be his death, perhaps because a prophecy had been given at the Temple at Delphi that Sparta should be saved by the death of one of her kings of the race of Hercules. He was allowed by law to take with him 300 men, and these he chose most carefully, not merely for their strength and valor, but selecting those who had sons, so that no family might be altogether destroyed. These Spartans, with their helots or slaves, made up his own share of the numbers, but all the army was under his generalship. It is even said that the 300 celebrated their own funeral rites before they set out lest they should be deprived of them by the enemy, since, as we have already seen, it was the Greek belief that the spirits of the dead found no rest till their obsequies had been performed. Such preparations did not daunt the spirits of Leonidas and his men, and his wife, Gorgo, not a woman to be faint-hearted or hold him back. Long before, when she was a very little girl, a word of hers had saved her father from listening to a traitorous message from the King of Persia; and every Spartan lady was bred up to be able to say to those she best loved that they must come home from battle "with the shield or carried upon it."

Why did the Spartans celebrate their funeral rites before they departed?

"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.

A PLEA FOR A LONG WALK

Sir—In these days of increasing rapid artificial locomotion, may I be permitted to say a word in favor of a very worthy and valuable old friend of mine, Mr. Long-Walk?

I am afraid that this good gentleman is in danger of getting neglected, if not forgotten. We live in days of water trips and land trips, excursions by sea, road, and rail—bicycles and tricycles, tram cars and motor cars, hansom cabs and ugly cabs; but in my humble opinion good honest walking exercise for health beats all other kinds of locomotion into a cocked hat. In rapid traveling all the finer nerves, senses, and vessels are "rush" and unduly excited, but in walking every particle of the human frame, and even the moral faculties, are evenly and naturally brought into exercise. It is the best discipline and physical mental tonic in the world. Limbs, body, muscles, lungs, chest, heart, digestion, breathing, are healthily brought into normal operation, while. especially in the long distance walk, the exercise of patience, perseverance, industry, energy, perception, and reflection—and, indeed, all the senses and moral faculties—are elevated and cultivated healthfully and naturally. Many never know the beauty of it because they never go far enough: exercise and hard work should never be relinquished at any age or by either sex. Heart disease, faintness, and sudden death, and even crime, are far more due to the absence of wholesome normal exercise and taste than to anything else, to enervating luxuries rather than to hill climbing.

I usually give myself a holiday on a birthday, and as I lately reached my 63rd I determined to give myself a day with my old friend Mr. Long-Walk, and decided to tramp to the city of Wells and back for my birthday holiday—a distance of about forty-two miles. Fortune favors the brave, and, thanks to a mosquito that pitched on my nose and was just commencing operations, I woke very early in the morning. It is an ill wind that blows no one any good. Mosquitoes are early birds, but I stole a march on them. But to my journey.

I started at about 5 A.M., and proceeding via Dundry and Chow Stoke, reached Wells soon after 10 A.M. After attending the cathedral, I pursued my walk homeward by a different route,via Chewton Mendip, Farrington, Temple Cloud, Clutton, and Pensford.

To make a walk successful, mind and body should be free of burden. I never carry a stick on a long walk, but prefer to be perfectly free, giving Nature’s balancing poles—the pendulum arms—complete swing and absolute liberty. Walking exercises, together with a well-educated palate, are the greatest physicians in the world: no disease can withstand them. I returned from my forty-two miles tramp with birthday honors and reward. I had no headache on the following morning, but was up early in good form, fresh and ready for work. Forty-two miles may be too strong a dose for many, but I cannot too strongly recommend for a day’s companionship the society of my old and well-tried friend, Mr. Long-Walk.

Faithfully yours,

T. Thatcher

Among the large running birds are forms, like the African ostrich, in which the absence of powers of flight is largely compensated by the specialization of the legs for the purpose of rapid movement on the ground. For straightforward retreat in open country nothing could be more effective; but another kind of adaptation is required in birds like rails, which are deficient in powers of flight, and yet are able to run through thickly-growing vegetation with such rapidity as to commonly elude their enemies. This is rendered possible by the shape of their bodies, which are relatively narrow and flattened from side to side, so as to easily slip between the stems of grasses, rushes, and similar plants. Anyone who has pursued our native land-rail or corn-crake with intent to capture will have noted how extremely difficult it is even to get within sight of a bird of this sort.

Certain birds, unfortunately for themselves, have lost the power of flight without correspondingly increased powers of running, and have paid the penalty of extinction. Such an arrangement, as might be anticipated, was the result of evolution in islands devoid of any predatory ground-animals, and a classic example of it is afforded by the dodo and its allies, birds related to the pigeons. The dodo itself was a large and clumsy-looking species that at one time abounded in the island of Mauritius, which, like oceanic islands generally, possessed no native mammals, while its indigenous reptiles were only represented by lizards. The ubiquitous sailor, however, and the animals (especially swine) which he introduced, brought about the extinction of this helpless bird in less than a century after its first discovery in 1598. Its memory is now only kept green by a few contemporary drawings and descriptions, certain museum remains, and the proverb "as extinct as a dodo.” A similar fate must overtake any organism suddenly exposed to new and unfavorable conditions, if devoid of sufficient plasticity to rapidly accommodate itself to the altered environment.

"Cacti" by Ami Dave (2013)

Cacti are plants suited to the desert, and we must always keep this factor in mind when growing ornamental cacti in our gardens, for it helps us provide cacti with conditions that allow them to survive and thrive. For example, a cactus should never be watered over its body, as it will start to rot. This is because it is covered with a waxy coating which prevents water loss through evaporation. When one waters the cactus over its body, the waxy coating is washed away and the plant begins to rot. The amount of water that one must supply to the cactus is very much dependent upon the season and upon the climate of the place. During the summer season one should water cacti every four days, whereas in the rainy season, once every fifteen days is quite enough.

Cacti need a minimum of two and a half hours of sunlight per day; however, they should not be kept in the sun all day because they may wrinkle when exposed to too much bright sunlight. Unlike other plants, cacti produce carbon dioxide during the day and oxygen during the night, so they are ideal plants to be kept in bedrooms to freshen up the air at night.

If a cactus is to thrive and prosper, the size of the pot in which it is grown needs to be monitored carefully. The pot should always be a little smaller than the plant itself because it is only when the plant has to struggle to survive that it will thrive. If the pot is too spacious and the plant does not need to struggle, chances are that the cactus will die. Similarly, if a cactus shows no signs of growth, stop watering it. Watering should be resumed only when the plant begins to grow again.

The substrata of a cactus pot is ideally composed of pieces of broken bricks at the bottom, followed by a layer of charcoal above the bricks, and then coarse sand and pebbles above the charcoal. Leaf mould is the best manure.

Grafting cacti is very simple. A very small piece of the cactus plant should be stuck with tape to the plant that needs grafting. The smaller the piece, the easier it is to graft. To reproduce cacti, one has to simply cut off a piece of the cactus, allow it to dry for a few days, and then place it over the cacti substrate. It will automatically develop roots.

It is very easy to differentiate between cacti and other plants that look like cacti. All cacti have fine hair at the base of each thorn. The so-called “thorns” are in fact highly modified leaves which prevent loss of water through transpiration. If one ever gets pricked by cacti thorns, one should take tape, place it over the area where the thorns have penetrated the skin, and then peel it off. All of the thorns will get stuck to the tape and will be removed.

"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.

Based on this passage, which of the following might be true about the early history of modern physics?
