Many argue that knowledge gives you power. Nevertheless, we sometimes wish that we were never informed about something. Why do we feel this way? Do we really need knowledge to be happy? As for me, it seems that knowing more often leads to a life of worry and misery. If we never knew that there were better ways of doing things, then we wouldn't feel such a need for them. Knowledge only brings a want for more. For happiness, therefore, a sense of nothing would be beneficial. In addition, it is often better to enjoy, simply accepting the way things are, rather than knowing how they work. Why do we need water? Why do we need food? Isn't it more relaxing just to know that, without them, you wouldn't exist?

I'm not saying that knowledge is not good or powerful, but it just makes me consider whether or not we are truly better off with it. When I was younger, I found that I was happier most of the time and it was easier to feel ‘alive' because I didn't understand the complexities of life. After all, the more knowledge we gain, the more confusion we obtain to go along with it. The world is simpler in the dark than in the light of day.

Calligraphy is a unique art because, instead of painting a scene from nature or a portrait of a person, as a traditional artist may do, the calligrapher's purpose and pleasure is the creation of beautiful words or letters, called characters, in Asian writing systems. This is done using the simplest of tools: a brush, ink, and paper. ...... (중략) ...... The meaning of individual characters in very old works of calligraphy is often unknown, but it doesn't matter, because the point is not to "read" the painting but to appreciate its elegance, simplicity, and beauty. The very best calligraphers are said to reveal deep aspects of their personality or "soul" in the form and flow of the characters they paint.

Pesticides are widely used to control pests such as mosquitoes. In a recent study, though, a new pesticide greatly reduced mosquito populations, but failed to kill every mosquito: many survived the pesticide attack. This happened because those mosquitoes had special variations in their genes, which made them resistant to the pesticide. These survivors subsequently produced offspring with the same natural resistance to the pesticide. Meanwhile, the pesticide had killed large numbers of the dragonflies that normally eat the mosquitoes. Ultimately, the mosquitoes' resistance to the pesticide was total, and their natural predators were few, leading their population to increase.

Walking down the street, you may not even notice the trees, but, according to a new study, they do a lot more than give shade. Environmental scientists chose two Chicago public housing projects, both of which had some buildings with lots of trees nearby, and some with practically none. According to the study, violence and property crimes were nearly twice as high in sections of the buildings where vegetation was low, compared with the sections where vegetation was high. Why? One explanation: Greenery creates a natural gathering space for neighbors and, ultimately, stronger bonds in the community. This can also create an atmosphere where children are better supervised, and buildings better watched.

A wealth of statistics gathered over time, across cultures and by various methodologies, strongly supports the notion that people become more aggressive in hot temperatures. More violent crimes have occurred in summer than in winter, during hotter years than during cooler, and in hotter cities than in cooler ones at any given time. Indirect acts of aggression or violence also increase whenever there is unusually hot weather. As temperatures grow uncomfortable, subjects in scientific experiments become more likely to interpret a normal action as being hostile. Similarly, drivers in cars lacking air-conditioning become more inclined to act out road rage towards motorists whose cars are in their way and moving too slowly.

Has the smell of something ever made you think of a spring day? Have some scents made you happy? Scientists discovered what certain smells do. One thing they know is that lemons remind people of things that are fresh and clean. People who make cleaners and soaps for the home often use a lemon scent. The smell of vanilla helps people relax. It may be very helpful for patients in hospitals. Cinnamon and apple smells remind many people of their homes. Some stores put these scents in the air to make customers comfortable. That way they'll want to buy more. It was discovered that scents can change the way you feel.

Many of us try to ignore our bodies. We try to escape from them to a fantasy world where flesh and blood don't exist. Our awareness of our bodies is mainly negative, and we criticize them as ugly and fat. Our self-image is so distorted that we believe ourselves fatter than we really are. However, we should see ourselves more realistically and become alert to the connection between mind and body. If our psychological needs are ignored, we will not be emotionally healthy. We have to accept what we cannot change, including our body's individual build and bone structure, and its need for exercise, rest, and food. When our bodies are well cared for, our minds function properly, too. Becoming whole means uniting both mind and body.

Is your child's homework a struggle? Although many parents would like to be involved in their child's learning, they don't think they have the right knowledge and skills to properly do so. Times have changed so much since many parents were at school, that teaching methods are now often completely different. For this reason, many parents would like schools to run sessions helping them to understand the curriculum, modern teaching methods, and the way children learn. That is to say, it is necessary for schools to open courses to give parents various tips on how to help their children learn.

Not many people consider illiteracy to be a disability. However, the illiterate face enormous problems in our community. Those who cannot read or write are extremely limited in what they can do. They can't use the Internet, read a subway sign, or order from a menu, and they can only choose products already familiar to them in a supermarket. Another problem is that the illiterate cannot access education. Those who are illiterate find it impossible to take courses that might improve their chances of employment. Finally, they have trouble helping their children to learn. They are unable to help with homework and will do anything to avoid a meeting with a teacher for fear of embarrassing their child or themselves.

Back in 18th century Europe, Louis XV made it fashionable for men to powder their noses and rouge their lips. The Beatles in the 1960s broke women's hearts with their long hair and thin, boyish figures. Nowadays singers like Big Bang put on smoky eye makeup, while the main actors in "Boys Over Flowers" enjoy pastel sweaters and curly hair. Middle-aged men, like women, are obsessed with perfect skin and thin waistlines. Flawless skin and colorful clothes are the key to completing the pretty boy look. Men who want to be beautiful also show interest in floral prints and pastel colors. Women are no longer the only customers.

In court cases that involve the presentation of scientific evidence, defense lawyers and their opponent prosecution lawyers usually use scientists who interpret data in a way that is favorable to their clients. This causes a problem for judges because they usually do not have the scientific knowledge to fairly decide a case based on this conflicting evidence. To make matters worse, opposing sides will very rarely agree on the interpretation of scientific data regarding their case. To solve this problem, judges are now allowed to recruit their own independent scientists. by providing unbiased expert opinion,A judge can provide a common ground for all sides to start from.

A hybrid vehicle is one that is powered by a combination of two different types of engine. The most common type of hybrid car is the gasoline-electric type. These cars use fuel to power small engines and batteries to run electric motors. The fuel engines are used to recharge the cars' batteries, which in turn supply power to an electric motor. Together, the fuel engine and the electric motor provide an amount of power that is strong enough to run a car at very reasonable rates. Today, because of people's concerns about the environment, particularly air pollution, hybrid cars are beginning to replace fuel-only models.

Do you think broccoli tastes bitter? Don't blame the cook! Researchers say that what tastes good or bad can depend on the taster's genes. Genes determine the color of your eyes and the shape of your face. Genes also determine how many taste buds are on your tongue. Some people have many taste buds. Because of this, they find the flavor of some foods unpleasantly strong. Broccoli tastes very bitter to them.

With the Industrial Revolution, people's lives underwent enormous changes. Prior to the nineteenth century, it could take weeks to produce a single shirt. Wool had to be turned into yarn, then dyed, made into fabric, and sewn all by hand. With machines, the time for producing a shirt was suddenly reduced to a matter of days. But the revolution did not decrease the working hours of most common people, who found themselves working up to 18 hours a day or more. Craftsmen such as tailors and carpenters now had to work much longer hours than they did previously, and sell their goods more cheaply, just to stay in business. Another change was that whole villages started to be built around factories, providing families with jobs, houses, schools, churches, and stores — all in one place.
