The Scientific Method

If you drop your shoe and a coin side by side, they hit the ground at the same time. Why does not the shoe get there first, since gravity is pulling harder on it? How does the lens of your eye work, and why do your eye’s muscles need to squash its lens into different shapes in order to focus on objects nearby or far away? These are the kinds of questions that physics tries to answer about the behavior of light and matter, the two things that the universe is made of.

Until very recently in history, no progress was made in answering questions like these. Worse than that, the wrong answers written by thinkers like the ancient Greek physicist Aristotle were accepted without question for thousands of years. Why is it that scientific knowledge has progressed more since the Renaissance than it had in all the preceding millennia since the beginning of recorded history? Undoubtedly the industrial revolution is part of the answer. Building its centerpiece, the steam engine, required improved techniques for precise construction and measurement (early on, it was considered a major advance when English machine shops learned to build pistons and cylinders that fit together with a gap narrower than the thickness of a penny). But even before the industrial revolution, the pace of discovery had picked up, mainly because of the introduction of the modern scientific method. Although it evolved over time, most scientists today would agree on something like the following list of the basic principles of the scientific method:

Science is a cycle of theory and experiment.
Scientific theories are created to explain the results of experiments that were created under certain conditions. A successful theory will also make new predictions about new experiments under new conditions. Eventually, though, it always seems to happen that a new experiment comes along, showing that under certain conditions the theory is not a good approximation or is not valid at all. The ball is then back in the theorists’ court. If an experiment disagrees with the current theory, the theory has to be changed, not the experiment.

Theories should both predict and explain.

——————————————————————————————————————————————————————————————————————————————————

Experiments should be reproducible.
An experiment should be treated with suspicion if it only works for one person, or only in one part of the world. Anyone with the necessary skills and equipment should be able to get the same results from the same experiment. This implies that science transcends national and ethnic boundaries; you can be sure that nobody is doing actual science who claims that their work is “Aryan, not Jewish,” “Marxist, not bourgeois,” or “Christian, not atheistic.” An experiment cannot be reproduced if it is secret, so science is necessarily a public enterprise.

As an example of the cycle of theory and experiment, a vital step toward modern chemistry was the experimental observation that the chemical elements could not be transformed into each other, e.g., lead could not be turned into gold. This led to the theory that chemical reactions consisted of rearrangements of the elements in different combinations, without any change in the identities of the elements themselves. The theory worked for hundreds of years, and was confirmed experimentally over a wide range of pressures and temperatures and with many combinations of elements. Only in the twentieth century did we learn that one element could be trans-formed into one another under the conditions of extremely high pressure and temperature existing in a nuclear bomb or inside a star. That observation did not completely invalidate the original theory of the immutability of the elements, but it showed that it was only an approximation, valid at ordinary temperatures and pressures.

The scientific method as described here is an idealization, and should not be understood as a set procedure for doing science. Scientists have as many weaknesses and character flaws as any other group, and it is common for scientists to try to discredit other people’s experiments when the results run contrary to their own favored point of view. Successful science also has more to do with luck, intuition, and creativity than most people realize, and the restrictions of the scientific method do not stifle individuality and self-expression any more than the fugue and sonata forms stifled Bach and Haydn. There is a recent tendency among social scientists to go even further and to deny that the scientific method even exists, claiming that science is no more than an arbitrary social system that determines what ideas to accept based on an in-group’s criteria. I think that is going too far. If science is an arbitrary social ritual, it would seem difficult to explain its effectiveness in building such useful items as airplanes, CD players, and sewers. If alchemy and astrology were no less scientific in their methods than chemistry and astronomy, what was it that kept them from producing anything useful?

Describing Distance and Time in Physics

Center-of-mass motion in one dimension is particularly easy to deal with because all the information about it can be encapsulated in two variables: xx, the position of the center of mass relative to the origin, and tt, which measures a point in time. For instance, if someone supplied you with a sufficiently detailed table of xx and tt values, you would know pretty much all there was to know about the motion of the object’s center of mass.

A point in time as opposed to duration
In ordinary speech, we use the word “time” in two different senses, which are to be distinguished in physics. It can be used, as in “a short time” or “our time here on Earth,” to mean a length or duration of time, or it can be used to indicate a clock reading, as in “I did not know what time it was,” or “now is the time.” In symbols, tt is ordinarily used to mean a point in time, while ΔtΔt signifies an interval or duration in time. The capital Greek letter delta, ΔΔ, means “the change in…,” i.e. a duration in time is the change or difference between one clock reading and another. The notation ΔtΔt does not signify the product of two numbers, ΔΔ and tt, but rather one single number, ΔtΔt. If a matinee begins at a point in time t=1t=1 o’clock and ends at t=3t=3 o’clock, the duration of the movie was the change in tt,

Δt=3 hours−1 hour= 2 hours.
Δt=3 hours−1 hour= 2 hours.

To avoid the use of negative numbers for ΔtΔt, we write the clock reading “after” to the left of the minus sign, and the clock reading “before” to the right of the minus sign. A more specific definition of the delta notation is therefore that delta stands for “after minus before.”

Even though our definition of the delta notation guarantees that ΔtΔt is positive, there is no reason why tt cannot be negative. If tt could not be negative, what would have happened one second before t=0?t=0? That does not mean that time “goes backward” in the sense that adults can shrink into infants and retreat into the womb. It just means that we have to pick a reference point and call it t=0t=0, and then times before that are represented by negative values of tt. An example is that a year like 2007 A.D. can be thought of as a positive tt value, while one like 370 B.C. is negative. Similarly, when you hear a countdown for a rocket launch, the phrase “t minus ten seconds” is a way of saying t=−10 st=−10 s, where t=0t=0 is the time of blastoff, and t>0t>0 refers to times after launch.

Although a point in time can be thought of as a clock reading, it is usually a good idea to avoid doing computations with expressions such as “2:35” that are combinations of hours and minutes. Times can instead be expressed entirely in terms of a single unit, such as hours. Fractions of an hour can be represented by decimals rather than minutes, and similarly if a problem is being worked in terms of minutes, decimals can be used instead of seconds.

Position as opposed to change in position
As with time, a distinction should be made between a point in space, symbolized as a coordinate xx, and a change in position, symbolized as ΔxΔx.

As with t, xt, x can be negative. If a train is moving down the tracks, not only do you have the freedom to choose any point along the tracks and call it x=0x=0, but it is also up to you to decide which side of the x=0x=0 point is positive xx and which side is negative xx.

Since we have defined the delta notation to mean “after minus before,” it is possible that ΔxΔx will be negative, unlike ΔtΔt, which is guaranteed to be positive. Suppose we are describing the motion of a train on tracks linking Tucson and Chicago. As shown in the figure, it is entirely up to you to decide which way is positive.

Note that in addition to xx and ΔxΔx, there is a third quantity we could define, which would be like an odometer reading, or actual distance traveled. If you drive 10 miles, make a U-turn, and drive back 10 miles, then your ΔxΔx is zero, but your car’s odometer reading has increased by 20 miles. However important the odometer reading is to car owners and used car dealers, it is not important in physics, and there is not even a standard name or notation for it. The change in position, ΔxΔx, is more useful because it is so much easier to calculate: to compute ΔxΔx, we only need to know the beginning and ending positions of the object, not all the information about how it got from one position to the other.

Frames of reference

——————————————————————————————————————————————————————————————————————————————————
Have you ever been sitting in a train in a station when suddenly you notice the station is moving backward? Most people would describe the situation by saying that you just failed to notice that the train was moving—it only seemed like the station was moving. But this shows there is yet a third arbitrary choice that goes into choosing a coordinate system: valid frames of reference can differ from each other by moving relative to one another. It might seem strange that anyone would bother with a coordinate system that was moving relative to Earth, but for instance the frame of reference moving along with a train might be far more convenient for describing things happening inside the train.

Chinese Secrets of Health

Chinese civilization has for thousands of years been one of the most advanced in the world. China is the land of grandiose architectural monuments, deeply-rooted traditions, unique philosophy and mysterious poetry, a diverse and difficult language, and an enigmatic mentality—a land of great accomplishments and terrible historical cataclysms. When speaking of China, one probably imagines Buddhist monks, temples in which students master the arts of peace and war, overpopulated megalopolises, exotic food, and incomprehensible (for a laowai: a foreigner) customs and lifestyle. But along with this, one of the most notable legacies of Chinese civilization is its traditional medicine.

It is not a secret that Chinese people live long—sometimes, incredibly long. If you have watched travel shows on Discovery or similar channels dedicated to China, you must have seen those old men and women, who, in their 80s or even 90s, look like a western person in their 60s. You must have also been amazed by how graciously and actively they move when doing physical exercises in open air—Chinese elderly people love them; it is called Tai Chi Quan, a mix of martial arts and gymnastics. Perhaps the question you kept asking yourself when seeing this was, “How? How is it possible that a person born somewhere in 1930s can look, move, and feel much younger that their age suggests?” One of the answers to this question is Chinese medicine.

——————————————————————————————————————————————————————————————————————————————————

Based on such an approach, Chinese doctors have for thousands of years developed their arts of therapy and treatment. China’s traditional medicine widely utilizes methods that are considered unconventional in the West, but which have nevertheless been proven in their efficiency. Along with Qi-gong, Tai Chi, or Wushu, all of which are closely related to manipulating energies, Chinese medicine also relies on herbs, acupuncture, and massage. However, as it often occurs in Asia, it is not all that simple.

Herbal therapy is probably among the most-commonly used types of therapy in China. It focuses on both treating a disease, and preventing it from occurring again in the future. There are 5,767 medicinal substances used by Chinese traditional medicine at the moment, and not all of them are herbs: a person undergoing such therapy may encounter rather exotic ingredients from which the ailments are made, such as insects, animal genitals, tiger claws, and so on. There are also several forms in which medicine can be made: 1) herbal decoctions, which are the most traditional and “acceptable” to the western mind. These decoctions can take a long time to make, and are famous (or better said, infamous) for their strong scent and taste; 2) herbal powders, from which, with the addition of water, the aforementioned “teas” can be made. Since they possess a weaker aroma and taste better, they are more popular in the West as compared to decoctions; 3) syrups, which are mostly used to treat children from light illnesses, such as cough, common cold, and sore throat; 4) liniments, compressors, and plasters applied externally. All of these, as well as other methods, are widely used in traditional Chinese medicine both inside and outside China (University of Minnesota). However, perhaps only in China you will be able to find the most efficient and exotic ailments, since some ingredients for them cannot be found outside of this country.

Massage is yet another common method of treatment widely used in Chinese medicine. The type of massage described below originates from Taiwan, and is called the Taiwanese knife massage. It dates back over 2000 years, and in other places outside of Taiwan, it has completely disappeared. As exotic as it sounds, the knife massage is also claimed to be more effective than more conventional massage techniques. These special knives are believed to penetrate muscles more deeply than in other methods, resulting in more noticeable positive health effects. The knives used for this type of massage are not regular meat cleavers—they are made specifically for masseurs, and are unlikely to cut a patient’s skin. Besides, the massage is performed through a towel, so the risks are minimal. Currently, there are about 2000 masseurs specializing in this type of massage. These days, there are around 2000 knife therapists in China, all of them living strict and disciplined lives, following special vegetarian diets, and practicing their art regularly (Skyscanner).

Yet another technique used throughout Asia for therapy and malady prevention is acupuncture, and China is the land in which the art of acupuncture had emerged and reached its climax. The first records mentioning acupuncture originated from approximately 1600 B.C., most of them being carvings made on bones, such as turtle-shells. Ancient acupuncture needles were made of stone, and were used to make skin incisions and stimulate specific points in the human body; it was believed Qi energy (or vital energy) could not flow freely through these points if they were functioning improperly, and acupuncture was supposed to break such “blocks” and let Qi flow naturally (British Acupuncture Council). Later, needles for acupuncture were made from bamboo (acos.rog). Acupuncturists are knowledgeable in using secret diagnostic techniques, and focus rather on a patient than on his or her sickness or symptoms (applying the aforementioned holistic approach). Each patient is seen as unique, and even if they possess the same diagnosis, the treatment may differ; two people with the same western diagnosis may well receive different acupuncture treatments (British Acupuncture Council).

As it can be seen, traditional Chinese medicine is as enigmatic and complex as Chinese culture. Based on principles alien to western conventional medicine, the oriental approach to therapy and treatment has been nevertheless proven to be efficient throughout centuries. Focusing on the relationship between Yin and Yang, on the flow of the vital Qi energy through a human body, Chinese therapists use a variety of methods to return a human body to healthy functioning, such as herbal decoctions, secret massage techniques, and the ancient art of acupuncture. Perhaps, people in the West should not neglect the effectiveness of Chinese medicine just because it does not use MRI scanners and modern diagnostics, and put more trust in the millenary traditions of Chinese people.

Description of a Desert

It is difficult to form a correct idea of a desert without having seen one. It is a vast plain of sands and stones, interspersed with mountains of various sizes and heights, usually without roads or shelters. They sometimes have springs of water, which burst forth, and create verdant spots.

——————————————————————————————————————————————————————————————————————————————————

Amid the desert, there are springs of water which burst forth and create verdant spots, called oases. There are thirty-two of these that contain fountains, and date and palm trees; twenty of them are inhabited. They serve as stopping places for the caravans, and often contain villages.

Were it not for these, no human being could cross this waste of burning sand. So violent, sometimes, is the burning wind that the scorching heat dries up the water of these springs, and then frequently, the most disastrous consequences follow.

In 1805, a caravan consisting of 2,000 persons and 1,800 camels, not finding water at the usual resting place, died of thirst, both men and animals. Storms of wind are more terrible in this desert than on the ocean. Vast surges and clouds of red sand are raised and rolled forward, burying everything in its way, and it is said that whole tribes have thus been swallowed up.

The situation of such is dreadful, and admits of no resource. Many perish, victims of the most horrible thirst. It is then that the value of a cup of water is truly felt.

To be thirsty in a desert, without water, exposed to the burning sun, without shelter, is the most terrible situation that a human being can be placed in, and one of the greatest sufferings that a human being can sustain; the tongue and lips swell; a hollow sound is heard in the ears, which brings on deafness, and the brain appears to grow thick and inflamed.

If, unfortunately, any one falls sick on the road, he or she must either endure the fatigue of traveling on a camel, (which is troublesome even to healthy people,) or he or she must be left behind on the sand, without any assistance, and remain so until a slow death comes to relieve him or her.

Types of Motion

If you had to think consciously in order to move your body, you would be severely disabled. Even walking, which we consider to be no great feat, requires an intricate series of motions your cerebrum would be utterly incapable of coordinating. The task of putting one foot in front of the other is controlled by the more primitive parts of your brain, the ones that have not changed much since the mammals and reptiles went their separate evolutionary ways. The thinking part of your brain limits itself to general directives such as “walk faster,” or “don’t step on her toes,” rather than micromanaging every contraction and relaxation of the hundred or so muscles of your hips, legs, and feet.

Physics is all about the conscious understanding of motion, but we are obviously not immediately prepared to understand the most complicated types of motion. Instead, we will use the divide-and-conquer technique. We will first classify the various types of motion, and then begin our campaign with an attack on the simplest cases. To make it clear what we are and are not ready to consider, we need to examine and define carefully what types of motion can exist.

Rigid-body motion distinguished from motion that changes an object’s shape
Nobody, with the possible exception of Fred Astaire, can simply glide forward without bending their joints. Walking is thus an example in which there is both a general motion of the whole object and a change in the shape of the object. Another example is the motion of a jiggling water balloon as it flies through the air. We are not presently attempting a mathematical description of the way in which the shape of an object changes. Motion without a change in shape is called rigid-body motion (the word “body” is often used in physics as a synonym for “object”).

Center-of-mass motion as opposed to rotation
A ballerina leaps into the air and spins around once before landing. We feel intuitively that her rigid-body motion while her feet are off the ground consists of two kinds of motion going on simultaneously: a rotation and a motion of her body as a whole through space, along an arc. It is not immediately obvious, however, what is the most useful way to define the distinction between rotation and motion through space. Imagine you attempt to balance a chair and it falls over. One person might say that the only motion was a rotation about the chair’s point of contact with the floor, but another might say there was both rotation and motion down and to the side.

It turns out there is one particularly natural and useful way to make a clear definition, but it requires a brief digression. Every object has a balance point, referred to in physics as the center of mass. For a two-dimensional object such as a cardboard cutout, the center of mass is the point at which you could hang the object from a string and make it balance. In the case of the ballerina (who is likely to be three-dimensional unless her diet is particularly severe), it might be a point either inside or outside her body, depending on how she holds her arms. Even if it is not practical to attach a string to the balance point itself, the center of mass can be defined.

Why is the center of mass concept relevant to the question of classifying rotational motion as opposed to motion through space? It turns out that the motion of an object’s center of mass is nearly always far simpler than the motion of any other part of the object. The ballerina’s body is a large object with a complex shape. We might expect that her motion would be much more complicated than the motion of a small, simply-shaped object, say a marble, thrown up at the same angle as the angle at which she leapt. But it turns out that the motion of the ballerina’s center of mass is exactly the same as the motion of the marble. That is, the motion of the center of mass is the same as the motion the ballerina would have if all her mass was concentrated at a point. By restricting our attention to the motion of the center of mass, we can therefore simplify things greatly.

We can now replace the ambiguous idea of “motion as a whole through space” with the more useful and better defined concept of “center-of-mass motion.” The motion of any rigid body can be cleanly split into rotation and center-of-mass motion. By this definition, the tipping chair does have both rotational and center-of-mass motion. Concentrating on the center of mass motion allows us to make a simplified model of the motion, as if a complicated object like a human body was just a marble or a point-like particle. Science really never deals with reality; it deals with models of reality.

Note that the word “center” in “center of mass” is not meant to imply that the center of mass must lie at the geometrical center of an object. A car wheel that has not been balanced properly has a center of mass that does not coincide with its geometrical center. An object such as the human body does not even have an obvious geometrical center.

It can be helpful to think of the center of mass as the average location of all the mass in the object. With this interpretation, we can see for example that raising your arms above your head raises your center of mass, since the higher position of the arms’ mass raises the average.

Center-of-mass motion in one dimension
In addition, there are cases in which the center of mass moves along a straight line, such as objects falling straight down, or a car that speeds up and slows down but does not turn.

Note that even though we are not explicitly studying the more complex aspects of motion, we can still analyze the center-of-mass motion while ignoring other types of motion that might be occurring simultaneously. For instance, if a cat is falling out of a tree and is initially upside-down, it goes through a series of contortions that bring its feet under it. This is definitely not an example of rigid-body motion, but we can still analyze the motion of the cat’s center of mass just as we would for a dropping rock.

Wonders of the Ancient World

Sometimes it may seem that historians already know everything possible about the ancient world. Indeed, scientists have found ways to glance at the very beginning of time, starting from the moment Earth appeared, through the age of bacteria, dinosaurs, primitive tribal societies, and until the most recent events. This does not mean there are no mysteries left, or no questions are unanswered, though. On the contrary, historians all over the world keep introducing theories explaining this or that historical phenomenon. And there are many of them in need of being explained: myths and legends such as the city of Atlantis, or why some figures on the Mayan and Aztec graves strongly resemble people in spacesuits, or speculations about how Stonehenge was built.

In fact, the latter—meaning ancient architecture in general—is often the subject of either debates or admiration (or both). Historians and archaeologists, mystics, and conspiracy theorists, adventurers and common people around the world all agree that raising some of the most impressive constructions such as the pyramids of Giza or Angkor Wat, using relatively simple tools and engineering methods, required enormous resources, effort, and technical wit, to say the least. Regarding the times they were built in, these constructions can be rightfully called wonders of the ancient world. Let us take a look at some of them.

Any list of ancient wonders would not be full-fledged without the mention of Stonehenge—a gigantic ring of stones standing in the middle of Salisbury Plains in England. Being not the most beautiful wonder, Stonehenge still manages to inspire and impress; it is mostly its purpose and the way it was built, rather than its appearance, which intrigues. When it was first constructed, Stonehenge was a ring of huge megaliths standing on the ground, with another ring of megaliths on top of them; in other words, it was a structure of two circles, one lying upon the other. The construction is primitive, but the weight of some of the stones reaches 50 tons; the nearest quarry such stones could be extracted from is 18 miles away from the site. How did ancient people manage to transport megaliths? Why would they even want to do this, given that there was no dynamite, caterpillars, trucks, or other modern means of construction; respectively, transporting each megalith was a task of immense complication. There is evidence proving that works on the site where Stonehenge stands now started about 11,000 years ago, although the rocks were placed on their spots much later—only around 2,000 years B.C. The people who raised Stonehenge had no written language, their origins are unknown, as well as the purpose they worked on Stonehenge for such a long time. There are guesses that the stone rings were used for druid ceremonies, or as an ancient calendar, but an unequivocal explanation has not been provided yet.

Speaking of Asia, it is always a source of exotic and mind-boggling wonders, which have remained unknown to the public for a long time. Perhaps everyone in the West knows about the pyramids of Giza, the Rhodes Colossus, the lighthouse of Alexandria, or the statue of Zeus. What people seldom know is that in Asia, there are lots of architectural wonders that are in no ways inferior to those located in the western hemisphere. For example, the gigantic statue of Buddha in Leshan: located in Sichuan, China. This is the largest statue of Buddha in the world, carved from stone. 71 meters high and 24 meters wide, the Leshan Buddha is impressive—not only because witnessing it makes you think about how the ancient sculptors managed to carve such a tremendous figure out of a cliff, but also because it emits calm and antiquity. Its construction started during the reign of the Tang dynasty (around 713 A.C.), and lasted for almost a century; the Leshan Buddha’s head is decorated with 1021 buns, and the drainage system it secretly utilizes reflects the engineering proficiency of those who raised the statue—this system helps keep the statue from deterioration, so this is one of the reasons why it is still standing there almost in its original magnificence (TMW).

As we can see, antiquity has a lot of surprises. The age of gigantic constructions and engineering wonders did not start with the first skyscrapers in the United States; thousands of years ago, people raised huge buildings, using primitive tools and methods that were available back then. However, wonders like Stonehenge, the Great Wall of China, or the Leshan Buddha prove there is no limit and no obstacle for human inspiration and innovation.

         First of all, teenagers are the largest group of mallgoers. The boys saunter by in sneakers, T-shirts, and blue jeans, complete with a package of cigarettes sticking out of their pockets. The girls stumble along in high-heeled shoes and fancy hairstyles, with hairbrushes tucked in the rear pockets of their tight-fitting designer jeans. Traveling in a gang that resembles a wolf pack, the teenagers make the shopping mall their hunting ground. Their raised voices, loud laughter and occasional shouted obscenities can be heard from as for as half a mile away. They basically just come to “hang out”.

         Apart from teenagers and lovers, nuclear family members can also be identified as the largest group of mallgoers. Mom, Dad and little Jenny of Fred, visit the mall on Friday and Saturday evenings. Mom walks around looking at various things until she discovers that Jenny is seeing some of the special mall exhibits geared toward little children, or in the case of Fred, he is heading for the place that young boys find appealing. Indeed, the mall provides something special for every member of the nuclear family.
         In a word, the teenagers, lovers on dates, and the nuclear family make up the majority of mallgoers.There are also gray-hairs, whose attention may suddenly be caught by some modern gadgets. These people may end up spending little money, but they need not purchase anything to find pleasure at the mall. They are shopping for inexpensive recreation, and the mall provides it.

     The solo traveler can be his own master of the day, because he does not have to adhere to anyone else's schedule. He can relax as much as he wants; he can rest and loosen up as long as he likes. He might indulge in full days reading on the beach, take a leisurely hike, or sit on a bench admiring a work of art-all on his own. "The experiences are mine and mine alone, said a solo traveler. "I've really learned to enjoy spending time with myself.”

     Traveling solo also offers a great chance for reflection. As one travel memoir writer stated, "There is a soul-searching power in each adventure on your own." Getting to really know oneself is a wonderful by-product of a solo journey. Traveling alone allows one to witness how he reacts to different situations. Those reflections can help him to gain a deeper understanding of who he is and what matters to him. He will have a stronger sense of self and feel more self-assured.
     Solo travel can afford the traveler the necessary time and solitude for experiencing unexpected pleasures, building new relationships, enjoying the slow pace and the reflections of life. Aside from all the excitement and adventure it ultimately leads to self-discovery. The traveler, once hitting the road solo, will fall in love with it and the journey never ends.

     The most important function of holiday rituals is their role in maintaining and strengthening family ties. In fact, for relatives who live far apart, holiday rituals may be the glue that holds the family together. Rituals are a powerful marker of identity and group membership. Taking part in collective rituals creates feelings of belonging and increased generosity toward other members of the group. It's no surprise, then, that spending the holidays with the in-laws for the first time is often regarded as a rite of passage—a sign of true family membership.
     Holiday rituals strengthen family harmony. Sure, we might need to take three flights to get there. And our uncle might get drunk and start an argument with his son-in-law again.But when we evaluate past experiences, we tend to remember the best moments and the last moments. In other words, our memory of the family holiday will mostly consist of all the joyful rituals, the good food, and the warm goodbye hugs (after our uncle made up with his son-in-law). After getting back home, we'll have something to look forward to for next year.

         In addition to an improved appearance, increased physical strength produces stamina. A stronger, healthier body is obviously more capable of working harder and, in fact, of withstanding normal fatigue.  A worker who exercises should be able to complete a forty-hour week and still retain enough energy for shopping and housework. Similarly, a student who goes to school, keeps house and perhaps works part-time should accomplish tasks more efficiently- Equally important, this stamina helps to keep off illnesses such as colds and influenza.
