Who in Rome could miss out on a chance to visit Vatican City, the place where the Pope lives? It is known as the smallest state in the world. In fact, it takes only thirty minutes to walk from one border to the other! I was overwhelmed, however, by the collection of sculptures and paintings in the Vatican Museums. The Creation of Adam, one of Michelangelo's masterpieces, on the ceiling of the Sistine Chapel, still lingers in my mind. Although I knew photographs are not allowed, the masterpiece was so impressive that I almost took one. After looking around, we walked out to see many people lined up in front of a small store where green apple gelato was served. Suji convinced me to wait in line for over twenty minutes saying that it would be worth it. She was right: the gelato was out of this world.

After a couple of more days in Rome, we headed to Venice. The seaside city was a lot more romantic than Rome, but a lot more humid as well. Suji said she had to visit a friend, so she suggested that I explore the city on my own for a few hours. We could meet up at the train station later in the afternoon.

I decided to go to the Rialto Bridge first, so I started walking. Within moments, the winding alleys made my map almost useless. After some wandering, I was lucky enough to meet a group of tourists my age from Britain. They were headed to the Rialto Bridge too! The bridge itself was as elegant as people say it is, but I was more impressed by the beautiful view of the canal from the steps of the bridge. I said goodbye to my British friends and walked to St_ Mark's Square, one of the prime attractions of Venice. I had never seen so many pigeons in my life. They were so used to being around people that they would wait until people weren't paying attention and then steal their crackers! But what truly made me stop and stare in wonder were the beautiful buildings surrounding all three sides of the square. Along the buildings were shops selling beautiful glass pieces, gloves, and much more. After looking around for a while, I bought small glasses for my parents.

My trip to Venice would not be complete without a gondola ride along the Grand Canal, which snakes through the city in a large S shape. I was disappointed to find out the fare to ride the Grand Canal by myself was so expensive that I could not afford it. The moment I was turning back, I saw my British tourist friends walking toward the ticket office. We shared the fare and we commented on the unique differences of the buildings along the canal. We had a nice chat, took some great pictures, and exchanged email addresses before we got off the gondola.

My trip to Italy was definitely an experience of a lifetime. I hope my next trip can be to England to visit my British friends. People say that the world is a book, and that those who do not travel read only one of the pages in it. So far, I have read two pages. I hope I have opportunities to read many more pages.

An eco-friendly way of life is not about changing the entire world overnight. It is about becoming aware of your own wasteful ways and then helping others become aware of theirs. After awareness comes the process of adopting slightly different ways of doing some daily tasks. When you do these things, you are keeping your environmental bank account full. When you go one step further and help others do them too, you are an activist and big changes can happen.

Every year thousands upon thousands of tons of electronics, from air conditioners to smartphones, are thrown out. This adds up to huge amounts of waste which has to be managed, especially for smaller countries like Korea. Is it possible that electronics waste is actually a resource? Like a mine in the ground, many people are beginning to think of electronics waste as "urban mines" because of the amount of gold, silver, copper, plastic, and steel that is waiting to be used again. To manufacture electronics products, resources such as gold, silver, copper, glass, plastic, and steel must be mined, purchased, or produced. As resources become harder to get, urban mines may become a more economical solution. About one ton of rock must be dug up in a mine to get around five grams of gold; however, one ton of mobile phones may contain around 300 grams of gold, in addition to other recoverable materials. The potential value of urban mines increases when resources become expensive and waste is not recycled. Although electronics waste may be seen from an economic point of view, there is another side to this story: the environmental issue. Recycling electronics waste can lower ecological damage from traditional mines and decrease air pollution from transporting materials over long distances. Moving forward does not always mean making new things; sometimes looking at an old problem from a new perspective is the simplest solution.

I was thrilled when my cousin, Suji, invited me to Italy, a country in southern Europe that looks like a boot. She had a few days off from studying music in a conservatory, so we could spend a week together in Rome and Venice. I had never been abroad by myself, and I was a bit worried, but after the long flight for twelve hours, I was pleased to be greeted by my cousin at Leonardo da Vinci International Airport in Rome. Since Italy is seven hours behind Seoul, I was quite exhausted and sleepy when I got there. However, I forced myself to stay awake to begin my trip in earnest.

Rome was like a giant museum to me. We began our sightseeing at the Colosseum. Nowadays, we can only see a part of what was once the greatest structure in the ancient world. It amazed me to think that people could build such a structure without modern construction equipment. The Colosseum has eighty arches through which about fifty thousand people could go in and out in fifteen minutes! As I reached the top of the stairs inside, I looked down and I could almost hear the cheer of the crowd.
evh-403
Suji and I walked along a path leading away from the Colosseum and heard the sound of falling water. We knew instantly that we were near the famous Trevi Fountain. Legend says that a single coin thrown into the fountain will ensure a return to Rome, a second coin will bring true love, and a third coin marriage! I threw one over my shoulder, wishing a return to Italy someday. I found it interesting that even on the other side of the world, people still wish for simple things like happiness, love, and marriage.

"Going green" seems to be all the rage these days. Stores and companies use phrases like this to promote their businesses as eco-friendly. It makes sense to try to live in a way that does not harm the environment, but is it easy to go green? In your home, for example, do you always unplug your TV when you aren't watching it? Do stores in your neighborhood always keep their doors shut when the heaters or air conditioners are on? Probably not. Some innovators have taken on the challenge of "going green," and have come up with some brilliant ideas to make "going green" easier and simpler.

Everyone has things that are no longer of any use, and chances are, those things will eventually get thrown away. However, some of the things that get thrown out are still useful to other people. Goedzak is a Dutch way of allowing people to get second-hand things that might otherwise be thrown away. It is a special garbage bag that can be filled with used, but still usable items. Placing the bag outside on the pavement makes whatever is in it available to anyone in the community. Goedzak's bright color attracts attention while the transparent side of the bag reveals its contents. People can help themselves to anything they like. What an idea! These transparent garbage containers have helped many Dutch people go greener by reducing the amount of trash going to landfills.

According to the Food and Agriculture Organization (FAO) of the United Nations, a third of global food production goes into trash bins annually. In Germany alone, around eleven million tons of food are wasted every year. Having been founded to tackle this problem on a local scale, the online platform, "foodsharing" allows extra food in your fridge or cupboard to be distributed to neighbors. The basic concept is simple: people sharing food. The only rule is not to pass anything on to others that you wouldn't eat yourself. This project may change the way people think about food: if food is not shared, it is wasted.

Drink and eat it! Using disposable cups may be convenient, but it is not necessarily eco-friendly. They are a massive source of waste. Every year, people in the U.S. use over 100 billion disposable cups, and Koreans dispose of over 15 billion cups each year. That's what drove a few novel designers to come up with edible coffee cups. A cookie forms the main structure, with a white chocolate layer on the inside and a thin layer of sugar paper on the outside. This structure allows you to drink coffee without finding yourself holding a soaked mess. You can think of it as a treat for coffee! You may have to consume extra sugar, but it will definitely create less waste.

Holes mean a lot. What can you do to go green when you have 500 photocopies to make? Many green strategies focus on using less paper, like printing on both sides. Another green strategy is to use less ink, which is what many people already do. But what if you could take it a step further? That's what Ecofont is. A designer thought that if he could create fonts that have tiny holes in them, he might be able to make more efficient use of the amount of ink used. In fact, Ecofont uses about a fifth less ink than traditional fonts without ruining readability. The brilliance of Ecofont is the different perspective it takes on going green: the use of less ink by the font.

Do you sometimes feel like you don't love your life? Like, deep inside, something is missing? That's because we are living someone else's life. We allow other people to influence our choices. We are trying to meet their expectations. Social pressure is deceiving ― we are all impacted without noticing it. Before we realize we are losing ownership of our lives, we end up envying how other people live. Then, we can only see the greener grass ― ours is never good enough. To regain that passion for the life you want, you must recover control of your choices. No one but yourself can choose how you live. But, how? The first step to getting rid of expectations is to treat yourself kindly. You can't truly love other people if you don't love yourself first. When we accept who we are, there's no room for other's expectations.

One of the big questions faced this past year was how to keep innovation rolling when people were working entirely virtually. But experts say that digital work didn't have a negative effect on innovation and creativity. Working within limits pushes us to solve problems. Overall, virtual meeting platforms put more constraints on communication and collaboration than face-to-face settings. For instance, with the press of a button, virtual meeting hosts can control the size of breakout groups and enforce time constraints; only one person can speak at a time; nonverbal signals, particularly those below the shoulders, are diminished; "seating arrangements" are assigned by the platform, not by individuals; and visual access to others may be limited by the size of each participant's screen. Such restrictions are likely to stretch participants beyond their usual ways of thinking, boosting creativity.

The law of demand is that the demand for goods and services increases as prices fall, and the demand falls as prices increase. Giffen goods are special types of products for which the traditional law of demand does not apply. Instead of switching to cheaper replacements, consumers demand more of giffen goods when the price increases and less of them when the price decreases. Taking an example, rice in China is a giffen good because people tend to purchase less of it when the price falls. The reason for this is, when the price of rice falls, people have more money to spend on other types of products such as meat and dairy and, therefore, change their spending pattern. On the other hand, as rice prices increase, people consume more rice.

In a study at Princeton University in 1992, research scientists looked at two different groups of mice. One group was made intellectually superior by modifying the gene for the glutamate receptor. Glutamate is a brain chemical that is necessary in learning. The other group was genetically manipulated to be intellectually inferior, also done by modifying the gene for the glutamate receptor. The smart mice were then raised in standard cages, while the inferior mice were raised in large cages with toys and exercise wheels and with lots of social interaction. At the end of the study, although the intellectually inferior mice were genetically handicapped, they were able to perform just as well as their genetic superiors. This was a real triumph for nurture over nature. Genes are turned on or off based on what is around you.

Researchers are working on a project that asks coastal towns how they are preparing for rising sea levels. Some towns have risk assessments; some towns even have a plan. But it's a rare town that is actually carrying out a plan. One reason we've failed to act on climate change is the common belief that it is far away in time and space. For decades, climate change was a prediction about the future, so scientists talked about it in the future tense. This became a habit ― so that even today many scientists still use the future tense, even though we know that a climate crisis is ongoing. Scientists also often focus on regions most affected by the crisis, such as Bangladesh or the West Antarctic Ice Sheet, which for most Americans are physically remote.

You can see how the sugar, the acid, the caffeine, and the artificial chemicals in sodas are really not good for you. Perhaps you might now understand that you should stop drinking them. However, if quitting sodas altogether sounds too difficult, cut down gradually. For example, replace one regular soft drink or one diet soda per day with another more healthy drink. Of course, the best choice would be water. Water has no calories, no acid, no caffeine, and no chemicals of any kind. And if you want something to add a boost of flavor, put a slice of lemon in the water. If you can't break your soda drinking habits in a short period of time, don't be too hard on yourself. Once you start cutting back, you are heading in the right direction.

A psychology professor raised a glass of water while teaching stress management principles to her students, and asked them, "How heavy is this glass of water I'm holding?" Students shouted out various answers. The professor replied, "The absolute weight of this glass doesn't matter. It depends on how long I hold it. If I hold it for a minute, it's quite light. But, if I hold it for a day straight, it will cause severe pain in my arm, forcing me to drop the glass to the floor. In each case, the weight of the glass is the same, but the longer I hold it, the heavier it feels to me." As the class nodded their heads in agreement, she continued, "Your stresses in life are like this glass of water. If you still feel the weight of yesterday's stress, it's a strong sign that it's time to put the glass down."

Your emotions deserve attention and give you important pieces of information. However, they can also sometimes be an unreliable, inaccurate source of information. You may feel a certain way, but that does not mean those feelings are reflections of the truth. You may feel sad and conclude that your friend is angry with you when her behavior simply reflects that she's having a bad day. You may feel depressed and decide that you did poorly in an interview when you did just fine. Your feelings can mislead you into thinking things that are not supported by facts.

Only a generation or two ago, mentioning the word algorithms would have drawn a blank from most people. Today, algorithms appear in every part of civilization. They are connected to everyday life. They're not just in your cell phone or your laptop but in your car, your house, your appliances, and your toys. Your bank is a huge web of algorithms, with humans turning the switches here and there. Algorithms schedule flights and then fly the airplanes. Algorithms run factories, trade goods, and keep records. If every algorithm suddenly stopped working, it would be the end of the world as we know it.

Despite all the high-tech devices that seem to deny the need for paper, paper use in the United States has nearly doubled recently. We now consume more paper than ever: 400 million tons globally and growing. Paper is not the only resource that we are using more of. Technological advances often come with the promise of using fewer materials. However, the reality is that they have historically caused more materials use, making us dependent on more natural resources. The world now consumes far more "stuff" than it ever has. We use twenty-seven times more industrial minerals, such as gold, copper, and rare metals, than we did just over a century ago. We also each individually use more resources. Much of that is due to our high-tech lifestyle.
You can see how the sugar, the acid, the caffeine, and the artificial chemicals in sodas are really not good for you. Perhaps you might now understand that you should stop drinking them. However, if quitting sodas altogether sounds too difficult, cut down gradually. For example, replace one regular soft drink or one diet soda per day with another more healthy drink. Of course, the best choice would be water. Water has no calories, no acid, no caffeine, and no chemicals of any kind. And if you want something to add a boost of flavor, put a slice of lemon in the water. If you can't break your soda drinking habits in a short period of time, don't be too hard on yourself. Once you start cutting back, you are heading in the right direction.

A psychology professor raised a glass of water while teaching stress management principles to her students, and asked them, "How heavy is this glass of water I'm holding?" Students shouted out various answers. The professor replied, "The absolute weight of this glass doesn't matter. It depends on how long I hold it. If I hold it for a minute, it's quite light. But, if I hold it for a day straight, it will cause severe pain in my arm, forcing me to drop the glass to the floor. In each case, the weight of the glass is the same, but the longer I hold it, the heavier it feels to me." As the class nodded their heads in agreement, she continued, "Your stresses in life are like this glass of water. If you still feel the weight of yesterday's stress, it's a strong sign that it's time to put the glass down."

Your emotions deserve attention and give you important pieces of information. However, they can also sometimes be an unreliable, inaccurate source of information. You may feel a certain way, but that does not mean those feelings are reflections of the truth. You may feel sad and conclude that your friend is angry with you when her behavior simply reflects that she's having a bad day. You may feel depressed and decide that you did poorly in an interview when you did just fine. Your feelings can mislead you into thinking things that are not supported by facts.

Only a generation or two ago, mentioning the word algorithms would have drawn a blank from most people. Today, algorithms appear in every part of civilization. They are connected to everyday life. They're not just in your cell phone or your laptop but in your car, your house, your appliances, and your toys. Your bank is a huge web of algorithms, with humans turning the switches here and there. Algorithms schedule flights and then fly the airplanes. Algorithms run factories, trade goods, and keep records. If every algorithm suddenly stopped working, it would be the end of the world as we know it.

Despite all the high-tech devices that seem to deny the need for paper, paper use in the United States has nearly doubled recently. We now consume more paper than ever: 400 million tons globally and growing. Paper is not the only resource that we are using more of. Technological advances often come with the promise of using fewer materials. However, the reality is that they have historically caused more materials use, making us dependent on more natural resources. The world now consumes far more "stuff" than it ever has. We use twenty-seven times more industrial minerals, such as gold, copper, and rare metals, than we did just over a century ago. We also each individually use more resources.

There are many team sports which require cooperation among the team members in order to win. Let' see the origins of a few of these sports. Field hockey has a long history. Four-thousand-year-old drawings of men playing a simple version of a hockey game have been found in tombs in Egypt. In the Middle Ages variations of hockey-like games were played in European countries. Later England modernized it. Chinese game called cuju meaning "kick a ball" existed during the 2nd and 3rd centuries BC and has been recognized as the first version of soccer with similar rules to the modern game. Players could use any part of their body except their hands. Later soccer-like games were played in Japan Australia and several countries in Europe. Now 211 countries around the world are registered as members of FIFA. Rowing has existed since humans first traveled on water by boat. The first reference to rowing as a sport comes from 15thcentury BC Egypt. It later spread throughout Europe. Modern rowing as a competitive sport goes back to England in the 18th century. Now one of the most famous competitions is the Oxford and Cambridge Boat Race.

When you eat fast food, such as pizza, hamburger, or fried chicken, what do you drink with it? Most people have a soda. When you go to the movies or when you just want something refreshing to satisfy your thirst, a soda is often the first choice. Soda, also called a soft drink, is a sweet drink with carbonation. People all over the world love sodas. Every year, Americans consume 170 liters of soda per person, and the British 100 liters. Of all age groups, teenagers drink the most soda. Most people, however, understand that sodas are not good for their health due to the ingredients. What is in a soda? Which ingredients are really not good for you?
esh-302
Everyone knows that soft drinks are loaded with large amounts of sugar. A typical 250ml can of soda contains 30 grams of sugar. WHO, the World Health Organization, recommends that people consume less than 25 grams of sugar a day. Therefore, if you drink one small can of soda, your daily sugar intake already exceeds the recommended amount. What is worse, people usually don't stop with one can. Having extra sugar means adding unnecessary calories. Over time, this can lead to obesity and other health problems, such as heart disease and diabetes. Even diet sodas are not safe. Diet sodas replace the sugar with artificial sweeteners. Artificial sweeteners provide a sweet, sugary taste with fewer calories. This may seem like a good thing, but it really isn't. According to a recent study, artificial sweeteners make you want more sweet foods. This means that you may easily gain weight if you keep drinking diet soda. In addition, artificial sweeteners are known to generate headaches, emotional disorders, and sleeping problems.

Most soda contains several types of acids. Acid is a chemical substance with a sour taste. When added to water, it produces a sharp flavor. Acid also delays the growth of bacteria, which extends the expiration date of a product. However, acid interferes with the body's ability to absorb calcium, and as a result, bone softening occurs. Also, the acid in sodas interacts with stomach acid, slowing digestion and blocking nutrient absorption. Furthermore, it can damage tooth enamel, the hard substance that protects your teeth. If you drink sodas regularly, your teeth decay more easily.

When you hear the word "caffeine," you most likely think of coffee. But some sodas, especially colas and carbonated energy drinks, also contain caffeine. Caffeine makes you feel more awake, but it may bring about an irregular heartbeat. A single can of cola may not affect you much, but if you consume colas regularly, they can make you feel more nervous and keep you from sleeping well at night. Artificial Colors and Artificial Flavors Soft drink companies attract consumers by adding bright colors and sweet flavors to their products. Most of these colors and flavors, however, are not natural. They are artificial chemicals. For example, the artificial color Yellow No_6, used in some pineapple juices, adds nothing to the taste. It is just there to make the drink look pretty. Also, the artificial flavor that gives the drink its pineapple taste is not real pineapple juice at all. Studies have shown that excessive consumption of these kinds of chemicals can create problems such as kidney disease and ADHD.

Darwin's "survival of the fittest" is universally regarded as a simple reality in the game of life. Successful play sometimes requires a degree of selfishness. However, across the animal kingdom, selfishness is only a very small part of an animal's life. Often, animals help each other and work together for the greater good. Cooperation prevails at every level of the animal kingdom. In the following three examples, it is inspiring to see how animals cooperate to help each other.
esh-202
Have you ever observed ants marching in and out of their nest? If so, it may have reminded you of a highway packed with cars. But this comparison is not appropriate. Ants never get into a traffic jam, no matter how fast they move or how many of them occupy the road. This is because their movements are based on cooperation. When there are a few ants moving in a single direction, some ants are likely to move slowly, some fast, and others even faster. As their number increases, however, they communicate with each other so that they all move at the same speed. The slow speed up while the fast and the superfast slow down. There are times when ants leaving the nest for food encounter other ants coming back with food on their backs. When this happens, the inbound ants, the ones carrying a burden, always have the right of way. Outbound ants turn to get out of the way, while inbound ants continue in a straight line. This arrangement makes sense because it is more difficult for inbound ants to change direction due to their heavy loads. Following these rules and cooperating in this way, ants improve the traffic flow and make the delivery of food to the nest more efficient.
esh-203
Fish also cooperate. As everyone knows, big fish often eat little fish. Sometimes, however, little fish help the big fish, so the big fish do not eat the little fish. Tiny fish, which scientists refer to as "cleaners," swim into the mouths of bigger fish, which are referred to as "clients." The cleaners eat parasites in the clients' mouths. After the cleaners do their job, the clients let them go, instead of swallowing them. The cleaners get a meal, and the clients get a healthier mouth. Sometimes the cleaner fish chew on the wall of the client fish's mouth. Although this may cause pain, the big fish still do not eat the little ones for two reasons. First, the cleaners are too small to satisfy their hunger. Second, it is hard to find good cleaners. Once the cleaners and the clients establish trust, the clients want to cooperate with the cleaners and keep them around.

Pied flycatchers are small birds that cooperate in dangerous situations. When a predator enters a flycatcher's area, the flycatcher makes a loud sound for help. Other flycatchers hear the call, and they come to help. As more and more birds join the group, the predator becomes frightened and runs away. It is important to note that flycatchers go to the aid of another bird in danger only if that bird has helped other birds in the past. They do not answer the calls of birds that have refused to help others before. More Info- Do you know how bats cooperate to survive? One kind of bat has a system of food sharing. Bats die if they go two nights without food. As hunting for blood—their only food-is not easy, younger bats fail to find food one night out of three. But hunger is rare because bats that find blood share it with bats that don't.
esh-205
Cooperation is a process that started with the first single-celled creatures. Living things, from their beginnings more than three billion years ago, took over the planet by learning to cooperate. We human beings cooperate in plenty of ways, from lining up at a bus stop to sharing knowledge on a website. Sometimes, however, human cooperation can break down. To foster cooperative success among humans, we should perhaps look to nature for inspiration.

Human processes differ from rational processes in their outcome. A process is rational if it always does the right thing based on the current information, given an ideal performance measure. In short, rational processes go by the book and assume that the book is actually correct. Human processes involve instinct, intuition, and other variables that don't necessarily reflect the book and may not even consider the existing data. As an example, the rational way to drive a car is to always follow the laws. However, traffic isn't rational; if you follow the laws precisely, you end up stuck somewhere because other drivers aren't following the laws precisely. To be successful, a self‑driving car must therefore act humanly, rather than rationally.

Like positive habits, bad habits exist on a continuum of easy‑to‑change and hard‑to‑change. When you get toward the "hard" end of the spectrum, note the language you hear - breaking bad habits and battling addiction. It's as if an unwanted behavior is a nefarious villain to be aggressively defeated. But this kind of language (and the approaches it spawns) frames these challenges in a way that isn't helpful or effective. I specifically hope we will stop using this phrase: "break a habit." This language misguides people. The word "break" sets the wrong expectation for how you get rid of a bad habit. This word implies that if you input a lot of force in one moment, the habit will be gone. However, that rarely works, because you usually cannot get rid of an unwanted habit by applying force one time.

A common but incorrect assumption is that we are creatures of reason when, in fact, we are creatures of both reason and emotion. We cannot get by on reason alone since any reason always eventually leads to a feeling. Should I get a wholegrain cereal or a chocolate cereal? I can list all the reasons I want, but the reasons have to be based on something. For example, if my goal is to eat healthy, I can choose the wholegrain cereal, but what is my reason for wanting to be healthy? I can list more and more reasons such as wanting to live longer, spending more quality time with loved ones, etc., but what are the reasons for those reasons? You should be able to see by now that reasons are ultimately based on non‑reason such as values, feelings, or emotions. These deep‑seated values, feelings, and emotions we have are rarely a result of reasoning, but can certainly be influenced by reasoning. We have values, feelings, and emotions before we begin to reason and long before we begin to reason effectively.

Electric communication is mainly known in fish. The electric signals are produced in special electric organs. When the signal is discharged the electric organ will be negatively loaded compared to the head and an electric field is created around the fish. A weak electric current is created also in ordinary muscle cells when they contract. In the electric organ the muscle cells are connected in larger chunks, which makes the total current intensity larger than in ordinary muscles. The fish varies the signals by changing the form of the electric field or the frequency of discharging. The system is only working over small distances, about one to two meters. This is an advantage since the species using the signal system often live in large groups with several other species. If many fish send out signals at the same time, the short range decreases the risk of interference.

Creativity can have an effect on productivity. Creativity leads some individuals to recognize problems that others do not see, but which may be very difficult. Charles Darwin's approach to the speciation problem is a good example of this; he chose a very difficult and tangled problem, speciation, which led him into a long period of data collection and deliberation. This choice of problem did not allow for a quick attack or a simple experiment. In such cases creativity may actually decrease productivity (as measured by publication counts) because effort is focused on difficult problems. For others, whose creativity is more focused on methods and technique, creativity may lead to solutions that drastically reduce the work necessary to solve a problem. We can see an example in the development of the polymerase chain reaction (PCR) which enables us to amplify small pieces of DNA in a short time. This type of creativity might reduce the number of steps or substitute steps that are less likely to fail, thus increasing productivity.

Robert Blattberg and Steven Hoch noted that, in a changing environment, it is not clear that consistency is always a virtue and that one of the advantages of human judgment is the ability to detect change. Thus, in changing environments, it might be advantageous to combine human judgment and statistical models. Blattberg and Hoch examined this possibility by having supermarket managers forecast demand for certain products and then creating a composite forecast by averaging these judgments with the forecasts of statistical models based on past data. The logic was that statistical models assume stable conditions and therefore cannot account for the effects on demand of novel events such as actions taken by competitors or the introduction of new products. Humans, however, can incorporate these novel factors in their judgments. The composite ─ or average of human judgments and statistical models ─ proved to be more accurate than either the statistical models or the managers working alone.

Free play is nature's means of teaching children that they are not helpless. In play, away from adults, children really do have control and can practice asserting it. In free play, children learn to make their own decisions, solve their own problems, create and follow rules, and get along with others as equals rather than as obedient or rebellious subordinates. In active outdoor play, children deliberately dose themselves with moderate amounts of fear and they thereby learn how to control not only their bodies, but also their fear. In social play children learn how to negotiate with others, how to please others, and how to manage and overcome the anger that can arise from conflicts. None of these lessons can be taught through verbal means; they can be learned only through experience, which free play provides.

Many early dot‑com investors focused almost entirely on revenue growth instead of net income. Many early dot‑com companies earned most of their revenue from selling advertising space on their Web sites. To boost reported revenue, some sites began exchanging ad space. Company A would put an ad for its Web site on company B's Web site, and company B would put an ad for its Web site on company A's Web site. No money ever changed hands, but each company recorded revenue (for the value of the space that it gave up on its site) and expense (for the value of its ad that it placed on the other company's site). This practice did little to boost net income and resulted in no additional cash inflow ─ but it did boost reported revenue. This practice was quickly put to an end because accountants felt that it did not meet the criteria of the revenue recognition principle.

Scholars of myth have long argued that myth gives structure and meaning to human life; that meaning is amplified when a myth evolves into a world. A virtual world's ability to fulfill needs grows when lots and lots of people believe in the world. Conversely, a virtual world cannot be long sustained by a mere handful of adherents. Consider the difference between a global sport and a game I invent with my nine friends and play regularly. My game might be a great game, one that is completely immersive, one that consumes all of my group's time and attention. If its reach is limited to the ten of us, though, then it's ultimately just a weird hobby, and it has limited social function. For a virtual world to provide lasting, wide‑ranging value, its participants must be a large enough group to be considered a society. When that threshold is reached, psychological value can turn into wide‑ranging social value.

It seems natural to describe certain environmental conditions as 'extreme', 'harsh', 'benign' or 'stressful'. It may seem obvious when conditions are 'extreme': the midday heat of a desert, the cold of an Antarctic winter, the salinity of the Great Salt Lake. But this only means that these conditions are extreme for us, given our particular physiological characteristics and tolerances. To a cactus there is nothing extreme about the desert conditions in which cacti have evolved; nor are the icy lands of Antarctica an extreme environment for penguins. It is lazy and dangerous for the ecologist to assume that all other organisms sense the environment in the way we do. Rather, the ecologist should try to gain a worm's‑eye or plant's‑eye view of the environment: to see the world as others see it. Emotive words like harsh and benign, even relativities such as hot and cold, should be used by ecologists only with care.
Robert Blattberg and Steven Hoch noted that, in a changing environment, it is not clear that consistency is always a virtue and that one of the advantages of human judgment is the ability to detect change. Thus, in changing environments, it might be advantageous to combine human judgment and statistical models. Blattberg and Hoch examined this possibility by having supermarket managers forecast demand for certain products and then creating a composite forecast by averaging these judgments with the forecasts of statistical models based on past data. The logic was that statistical models assume stable conditions and therefore cannot account for the effects on demand of novel events such as actions taken by competitors or the introduction of new products. Humans, however, can incorporate these novel factors in their judgments. The composite ─ or average of human judgments and statistical models ─ proved to be more accurate than either the statistical models or the managers working alone.

Free play is nature's means of teaching children that they are not helpless. In play, away from adults, children really do have control and can practice asserting it. In free play, children learn to make their own decisions, solve their own problems, create and follow rules, and get along with others as equals rather than as obedient or rebellious subordinates. In active outdoor play, children deliberately dose themselves with moderate amounts of fear and they thereby learn how to control not only their bodies, but also their fear. In social play children learn how to negotiate with others, how to please others, and how to manage and overcome the anger that can arise from conflicts. None of these lessons can be taught through verbal means; they can be learned only through experience, which free play provides.

Many early dot‑com investors focused almost entirely on revenue growth instead of net income. Many early dot‑com companies earned most of their revenue from selling advertising space on their Web sites. To boost reported revenue, some sites began exchanging ad space.

What consequences of eating too many grapes and other sweet fruit could there possibly be for our brains? A few large studies have helped to shed some light. In one, higher fruit intake in older, cognitively healthy adults was linked with less volume in the hippocampus. This finding was unusual, since people who eat more fruit usually display the benefits associated with a healthy diet. In this study, however, the researchers isolated various components of the subjects' diets and found that fruit didn't seem to be doing their memory centers any favors. Another study from the Mayo Clinic saw a similar inverse relationship between fruit intake and volume of the cortex, the large outer layer of the brain. Researchers in the latter study noted that excessive consumption of high‑sugar fruit (such as mangoes, bananas, and pineapples) may cause metabolic and cognitive problems as much as processed carbs do.

Winning turns on a self‑conscious awareness that others are watching. It's a lot easier to move under the radar when no one knows you and no one is paying attention. You can mess up and be rough and get dirty because no one even knows you're there. But as soon as you start to win, and others start to notice, you're suddenly aware that you're being observed. You're being judged. You worry that others will discover your flaws and weaknesses, and you start hiding your true personality, so you can be a good role model and good citizen and a leader that others can respect. There is nothing wrong with that. But if you do it at the expense of being who you really are, making decisions that please others instead of pleasing yourself, you're not going to be in that position very long. When you start apologizing for who you are, you stop growing and you stop winning. Permanently.

The above graph shows how often German children and young adults read books in 2022 according to age groups. In each age group except 12 to 13‑year‑olds, those who said they read books once a month or less accounted for the largest proportion. Of the 12 to 13‑year‑old group, 42% stated they read daily or several times a week, which was the highest share within that group. In the 14 to 15‑year‑old group, the percentage of teenagers who read daily or several times a week was three times higher than that of those who never read a book in the same age group. In the 16 to 17‑year‑old group, those who read between once a week and once every two weeks were less than 20%. More than one fifth of the age group of 18 to 19 years responded that they never read any book.

British photographer Julia Margaret Cameron is considered one of the greatest portrait photographers of the 19th century. Born in Calcutta, India, into a British family, Cameron was educated in France. Given a camera as a gift by her daughter in December 1863, she quickly and energetically devoted herself to the art of photography. She cleared out a chicken coop and converted it into studio space where she began to work as a photographer. Cameron made illustrative studio photographs, convincing friends and family members to pose for photographs, fitting them in theatrical costumes and carefully composing them into scenes. Criticized for her so‑called bad technique by art critics in her own time, she ignored convention and experimented with composition and focus. Later critics appreciated her valuing of spiritual depth over technical perfection and now consider her portraits to be among the finest expressions of the artistic possibilities of the medium.

Human beings like certainty. This liking stems from our ancient ancestors who needed to survive alongside saber‑toothed tigers and poisonous berries. Our brains evolved to help us attend to threats, keep away from them, and remain alive afterward. In fact, we learned that the more certain we were about something, the better chance we had of making the right choice. Is this berry the same shape as last time? The same size? If I know for certain it is, my brain will direct me to eat it because I know it's safe. And if I'm uncertain, my brain will send out a danger alert to protect me. The dependence on certainty all those millennia ago ensured our survival to the present day, and the danger‑alert system continues to protect us. This is achieved by our brains labeling new, vague, or unpredictable everyday events and experiences as uncertain. Our brains then generate sensations, thoughts, and action plans to keep us safe from the uncertain element, and we live to see another day.
