A bicycle is a pedal-powered two-wheeled vehicle that a person rides. The word bike is shorthand for bicycle, and it may also refer to a motorbike or scooter. Bicyclists are known as cyclists. People who ride bikes for sport or exercise are called recreational cyclists. Cycling is an excellent form of exercise that strengthens the muscles, increases cardiovascular health, and burns calories. It can be as low-intensity as walking or riding a stationary bike, or as challenging as cycling up and down hills. Cycling also improves coordination and stamina, and it is easier on the joints than many other forms of physical activity.

Cycling is one of the most popular sports in the world. It is fun, easy to learn, and can be adapted for different abilities. It provides a great workout, and it can be done at almost any time or place. Cycling can also be less expensive than most other forms of exercise. A good bicycle is important for anyone who wants to enjoy cycling.

The first step in learning to ride a bike is to get comfortable with the basic form. Begin by placing your right foot on the pedal and supporting yourself with your left leg. Start pedaling slowly and try to maintain your balance as you go. Once you have mastered the basics, begin to add speed and try to turn your handlebars. Be sure to keep your balance and always wear a helmet!

Bicycles have mechanical moving parts, and as such they require regular maintenance. Some of these can be done with simple tools, while others need to be serviced by a specialist. The International Organization for Standardization has a technical committee for cycles, TC149, which covers “Standardization in the field of bicycles, their components and accessories with particular reference to terminology, testing methods and requirements for performance and safety, and interchangeability.”

In addition to being an excellent form of exercise, biking is fun and social. It is a great way to spend time with friends, and it can even help you meet new people. Studies have shown that people who cycle regularly have lower rates of heart disease, diabetes, high blood pressure, and obesity than those who do not ride. Moreover, cycling is a good way to relieve stress. A study by the University of California found that socializing while cycling releases oxytocin, which helps you relax and feel calm.

The most common bicycle accidents involve the bicyclists themselves. These include failure to wear a helmet, going against the flow of traffic, running a stop sign, and swerving into oncoming or crossing traffic. Bicyclists can also injure themselves by crashing into trees, other bikes, or pedestrians. Fortunately, most bicycle accidents can be prevented by wearing a helmet and following the rules of the road. Always be sure to signal before turning and ride far enough out into the road to avoid obstacles such as storm grates, wet leaves, or railroad tracks. It is also a good idea to keep your eyes and ears open to other traffic and avoid blind corners.

Go is a fascinating game that has been around for thousands of years, with the earliest records of board layouts dating to at least 2,000 BCE. Today, it is played around the world in tournaments and casual games. Unlike chess, where the number of legal moves is limited to about 35, Go has many more spaces and an infinite number of possible configurations. This vastly increases the complexity of the game and makes it difficult for exhaustive computer programs to find the best moves.

The goal of the game is to capture the opponent’s groups, while preserving one’s own groups. The number of liberties (free points) that a group has is counted, and situations where mutually opposing groups must capture each other or die are called “capturing races” in Japanese (“semeai”). The more liberties a player’s groups have, the stronger they are.

Players can use a simple paper board and coins, plastic tokens or coffee beans for the stones, but more expensive traditional materials are still used by many. The most expensive Go sets include boards carved from slate or wood and stones crafted from transparent white shells. In addition, there are many specialized pieces of equipment that allow for different types of play, including mirrors, electronic devices and clocks to track time spent in each phase of the game.

For 40 years, geostationary environmental satellites known as the GOES have provided continuous imagery and data on atmospheric conditions and solar activity, or space weather, to support the National Weather Service’s forecasting and severe storm tracking operations. The GOES system consists of two satellites, GOES-East and GOES-West, which provide a nearly constant stream of real-time Earth observations across North America and the Pacific Ocean.

The GOES system also relays distress signals, or Search and Rescue Satellite Transmissions (S&RSAT), sent from people in aircraft or marine vessels to the nearest S&RSAT receiving station.

GOES data products are widely used by scientists, emergency management officials and private industry. The system’s data has contributed to safer transportation, improved agricultural productivity, and a better understanding of long-term climate conditions.

In 2020, GOES-16 and -17 helped forecasters and meteorologists prepare for and respond to 30 named storms — including six major hurricanes. GOES-16 and 17 have also contributed to the rapid detection and monitoring of wildfires, especially in areas where fires can quickly spread.

The GOES-R Series program is managed through an integrated NOAA/NASA office, with NOAA responsible for satellite operation and distribution of GOES data. NASA manages the design, build and launch of GOES satellites. NOAA maintains a full-time staff at the NOAA Satellite Operations Center in Maryland to perform mission operations for the GOES-R Series satellites.

Nice is a positive word, but many people use it without really knowing what it means. The etymology of the word suggests that it’s about being pleasing and agreeable, but personality psychology offers a different definition. A nice person is someone who demonstrates prosocial behaviors—those that are concerned with the well-being and safety of others. These include kindness, empathy, and generosity. They also take responsibility for their actions. Nice people often put the needs of others before their own and are generous with their time and resources.

But being a nice person isn’t the same as being a good person. In fact, the difference is much larger than people realize. People who are merely nice may display some of the same prosocial behaviors as good people, but they lack other important qualities. The true mark of a good person is that they’re willing to stand up for their values, even when it doesn’t benefit them in the long run.

The most common misconception is that being nice is synonymous with being a doormat. Nice people are generous with their time, money, and knowledge but they’re not willing to be taken advantage of by those who treat them like a doormat. They recognize the importance of reciprocity—one of Cialdini’s Principles of Influence—and they give back to those who help them in return.

A kind person isn’t a perfect one, but they do their best to own when they make a mistake and work to fix it. They also strive to avoid making the same mistake multiple times. They’re also a good listener. They care about other people’s feelings and are able to put themselves in their shoes, which helps them understand how other people feel and what they might need from them.

Being a nice person means being tolerant of people with different opinions, beliefs, and values. It’s about being accepting of everyone and wanting to help them feel at home. Nice people are friendly to their loved ones and extend this same kindness to those they meet.

Nice is a city in and the capital of the Alpes-Maritimes department on the Mediterranean coast of southeastern France. Known for its sunny climate and deep-blue sea, the Baie des Anges, it has been a popular destination for tourists since the 19th century. Its clear air and soft light have inspired many notable painters, including Marc Chagall, Henri Matisse, and Niki de Saint Phalle, as well as writers such as Friedrich Nietzsche, who wrote Thus Spoke Zarathustra there in the winter of 1883–84. It is considered the leading resort of the French Riviera. It is also a center for the arts and culture, with numerous museums, including the Musée Masséna. The city is the most important cultural and economic center of the Provence-Alpes-Cote d’Azur region. It is a major transportation hub and has the largest airport in southern France. It is also a major sports center, with a strong reputation for tennis and other sporting events.

Good is an adjective that means “pleasing, favorable, nice.” Things can be good, like a cup of coffee or the weather. But they can also be bad, like a long walk through a crowded city or eating spoiled food. Good is a noun, too, when used to describe a quality or a feeling. A person might be described as a good singer or a good seamstress, for example. In some contexts, the adverb well can be added after good to indicate how something is done or felt.

The notion of goodness has been central to the debate over how humans should live. Philosophers and religious thinkers have offered many different ideas about what the good life is, including hedonism, utilitarianism, naturalism, deontology, metaethics, and moral realism.

A common theme in discussions of the good life is the belief that it’s important to have a sense of meaning and purpose in your life. This is because it helps you cope with the ups and downs of life, making it more bearable. In addition, having a sense of purpose can help you feel better about yourself and what you’re doing in the world.

One way to achieve a sense of meaning and purpose is through religion. For many people, this is where they find their spirituality, a connection with something larger than themselves. Other people may find it through a hobby or sport. Still others might find it through relationships or community service. No matter what you do to make yourself feel good, it’s important to do it regularly. Taking time for yourself and spending it with loved ones can help you cope with stressors. It’s also important to take care of your health, so exercise and eat a balanced diet.

When writing articles, it’s crucial to do your research thoroughly. This will help you build credibility with your audience. Use reputable sources when possible and include multiple perspectives on your topic. You can also improve the readability of your article by breaking it up into shorter paragraphs and adding visual elements like charts, graphs, diagrams, or photographs.

If you want to write a good article, it’s important to know your audience and what they’re interested in. This will help you craft content that’s relevant to them and will keep them engaged. In addition, be sure to proofread your work before you publish it. Mistakes can reflect badly on your credibility and hurt your reputation.

A bicycle is a human-powered, two-wheeled vehicle for transporting the rider and cargo. Depending on the design and use, bikes can be extremely efficient in terms of the energy required to travel a given distance, although they also tend to be relatively heavy. A typical bicycle can be used to get to and from work or school for a small initial cost and very little annual running expense, making it an affordable means of transportation for the vast majority of the world’s population.

The bike consists of a frame, fork, wheels, tires and a saddle, and can be augmented with accessories such as handlebars, pedals, chains, derailleurs, seat posts, bells or horns, and cycling computers or GPS. There is a great deal of variety in the components and materials used to make bikes, and there are tradeoffs between price, weight, durability and performance. For example, a top-of-the-line carbon fiber racing bicycle can cost several thousand dollars while an inexpensive steel model may be adequate for casual riding or commuting to work and back.

It is important to find a bicycle that fits the rider well. The ideal saddle height allows the cyclist to comfortably reach the pedals at the bottom of the stroke without requiring excessive leg extension. It is also important to select a bicycle with enough gearing to allow the rider to maintain a constant pedaling rate, which reduces both fatigue and stress on the body. Most new bicycles are sold with a single speed drivetrain, but multi-speed models are available as an upgrade for those who want to increase their pedaling efficiency.

A bicycle’s brakes are a vital safety feature and are operated by levers mounted on the handlebars. The levers activate caliper brakes that clamp against the metal inner wheels. When a rider applies the brakes, kinetic energy is converted into heat that slows down the wheels and stops the bicycle.

Many bike owners add pegs (sometimes called “strike plates”) to one or both of the wheel hubs for additional traction or to provide a place for the rider to stand when stopping. Child-carrying seats, a rack and pannier bags for carrying cargo are also common accessories.

A bicycle’s frame is made of tubing, with a top tube that connects to the fork and seat tubes that connect to the handlebars. The frame is connected to the rest of the bicycle by bearings in a fork and headset assembly. There are three basic types of bicycle frames: upright, curved and dropped. Upright frames, the norm until the 1970s, curve gently back toward the rider for a comfortable upright position. Curved or drop handlebars curve forward and down, offering the rider a more aerodynamic crouched position while providing better braking control from the hands. Drop handlebars are more common on road and mountain bikes.

The game of go is widely recognized as being among the world’s most challenging. As a board game it has been played for centuries and continues to be an important part of Chinese culture. It is also a fascinating intellectual pursuit, and the game’s history has much to teach us about how intelligence evolves.

In ancient China, one of the four arts a cultivated scholar and gentleman was expected to master was go. This was because the game taught patience, perseverance, and how to focus one’s attention. It was also said that the way a person played go revealed their character and personality. In modern times, we play a much more relaxed version of the game but it remains an excellent mental exercise and one that can help to improve focus and concentration.

While the game of go has a long and distinguished history, it isn’t alone in its struggle for supremacy. There are a variety of other games that can challenge our cognitive abilities, including chess, backgammon, bridge and poker. However, the game of go is unique because it requires players to make decisions with incomplete information and a high degree of uncertainty. As a result, it has become a scientific research topic that has yielded many insights into decision making and cognitive processes.

One of NOAA’s most valuable assets is its fleet of geostationary operational environmental satellites (GOES). These spacecraft are designed to stay above a specific location on Earth and provide advanced imagery and data of atmospheric phenomena that directly impact public safety, protection of property, and the nation’s economic health and prosperity.

GOES satellites operate in geostationary orbit about 22,236 miles above the Earth’s equator. The GOES-R series, which includes GOES-16 and GOES-18, provides high-resolution imaging of Earth’s western hemisphere, real-time mapping of lightning activity, and observations of solar activity and space weather.

The GOES system is a NOAA/NASA joint project, with NOAA providing funding requirements and the spacecraft’s mission, and NASA responsible for the design, development and launch of each spacecraft and its instruments. The GOES system has been in service for 40 years and has become a critical part of NOAA’s National Weather Service operations.

In addition to geostationary imaging, the GOES-R satellites are equipped with an onboard Data Collection System (DCS) which relays environmental data transmissions from remotely located in-situ Automatic Data Collection Platforms (ADPs) to properly equipped receiving stations in radio view of the GOES satellites. These data are then used to create meteorological products such as radar maps, forecasts and advisories. The GOES satellites are also capable of receiving distress signals from people, aircraft and marine vessels and transmitting them to Search and Rescue Ground Stations for immediate action.

Nice is an adjective that describes something pleasant, friendly and agreeable. People who are nice are sociable and warm, and they always try to make others feel good about themselves. They are also thoughtful and generous, and they never expect anything in return for their kindness. Being nice comes naturally to some people, but for others, it is a learned trait that they have to work at.

One of the most important qualities of being nice is honesty. Nice people do not lie or embellish their experiences or accomplishments, and they are able to admit when they have made a mistake. They are also straightforward with their friends and colleagues, even when it means giving them constructive criticism. This honesty is what makes them so trustworthy and respected.

Another quality of being nice is openness. Nice people are willing to listen and accept other people’s beliefs, and they are not judgemental of those who disagree with them. They are also able to empathise with other people’s feelings and help them resolve their problems. Nice people are selfless and do not hold grudges, and they are able to give a shoulder to cry on when necessary.

People who are nice are able to motivate other people, and they have a special respect for their peers. They are able to encourage others to follow positive thoughts and reframe negative ones, so they can achieve their goals. They also give regular hugs to the people around them to make them feel better, and they constantly ask whether someone needs any support.

However, some nice people can become too focused on pleasing other people and may start to compromise their values. This can lead to a culture of mediocrity, which Wharton professor Adam Grant considers one of the biggest threats to psychological safety at work. In his podcast, he explains that this type of workplace culture promotes low-level behavior, where employees are so concerned with being liked that they do not care about the impact of their actions on their coworkers.

Nice is a beautiful city in southeastern France on the Mediterranean coast, located 13 kilometers (8 mi) from the principality of Monaco and 30 kilometres (19 mi) from the French-Italian border. Its clear air and soft light have attracted many painters, including Marc Chagall, Henri Matisse and Niki de Saint Phalle. In addition to being a popular tourist destination, Nice is also a center for finance and trade, and it has the largest business park in the Côte d’Azur region. It is also home to the headquarters of the Chambre de commerce et d’industrie Nice Côte d’Azur and the Port of Nice. The city has several museums, including the Museum of Contemporary Art and the Archaeological Museum of Antibes. A number of international writers have also found inspiration in Nice, such as Frank Harris, who wrote My Life and Loves here, Friedrich Nietzsche, who completed Thus Spoke Zarathustra, and Anton Chekhov, who wrote Three Sisters while living in the city for six winters.

The word good is the most general positive evaluation that can be used in a wide range of contexts. It is used to indicate that something has some positive attribute: “the soup was very good.” It can be used to describe an experience, a job, or anything else: “that was a really good book.” It is also an evaluative term: “That sounds like a great idea!”

The concept of the good has been central to moral deliberation for as long as there have been philosophers. There are many ways to approach the problem of defining the good, and it has been a source of disagreement.

For example, some philosophers have distinguished between attributive and predicative uses of the term. Geach, for instance, argued that the adverb good is always attributive; something only has the attribute “good” when it can be attributed to it. The predicative use of the term, on the other hand, corresponds roughly to the notion of value: a knife is valuable, for instance, but we can still argue about whether or not it’s good.

There is another, more important distinction that has been made about the good. Some philosophers have sought to define the good in terms of an object or activity. Others, most notably Aristotle and Immanuel Kant, have defined the good in terms of human flourishing or perfection. For Aristotle, the good life is a life of excellence, and to excel requires not just pleasure but the exercise of reason: the ability to think about what one should do and the motivation to do it.

Aristotle’s conception of the good has had a profound impact on subsequent philosophical thinking. Among other things, it influenced the Enlightenment discussions of “the good, the true, and the beautiful” in Kant’s Critique of Practical Reason. Aristotle’s view that the good life is the flourishing of reason was also influential on religious and philosophical schools that tended toward hedonism, such as the Epicureans.

Regardless of which stance is taken, the idea that there is a good is at the heart of most ethical theories. It is also at the center of much of philosophical literature and discourse.

A bicycle is a two-wheeled human-powered vehicle with a frame, wire-spoked wheels, seat, handlebars for steering and pedals for feet to push on. The most popular type of bike is a road bicycle that has flat handlebars for an upright riding position and multi-gear drivetrains to help the rider climb hills. These bikes often use disc or rim brakes and may come with accessories like fenders, racks and lights pre-installed.

The present world record for cycling is held by a man who left his home in 1962 and is still touring the globe as of 2016. The average speed of a person riding a bicycle on flat ground is between 20 and 30 miles per hour. This is faster than the pace that many people walk but not nearly as fast as a car drives.

In addition to being fun, bicycles provide an excellent form of exercise for the rider. Cycling improves balance, coordination and gait, and provides a full range of aerobic and muscle-strengthening benefits. It also reduces stress, and burns calories and fat. The environmental benefits of cycling are significant as well. One study found that commuting by bike for just one day instead of driving reduces a person’s carbon footprint by 67%.

Bicycling is a popular sport and recreational activity for both men and women of all ages. With the invention of the safe bicycle in the 1890s, what was once a dangerous toy for the upper classes became a practical mode of transportation and a popular pastime that could be enjoyed by people from all walks of life.

The most important part of a bicycle is the frame. The frame determines the size of the wheels, how fast the rider can go and whether or not it can take accessories like mudguards (fenders) and pannier racks. The frame also defines how far the seat can be adjusted from the handlebars, and determines how comfortable it is for the rider.

Other parts of the bike include the cranks, the chain, and the handlebars and pedals. The cranks are a set of metal rods that connect to the pedals. The chain runs from the cranks to the wheels. The pedals have a rubber cleat that grips the metal spokes of the wheel, and the wheels have a tire that wraps around them.

The bicycle is used as a mode of transport in cities and towns all over the world. In many cases, this is the primary mode of transport for commuters and shoppers. The bicycle is also popular for recreation, especially among children. It is also used for racing, and a racer’s bike can be worth tens of thousands of dollars. It is important for cyclists to understand the traffic laws in their areas, and to know how to keep their bikes safe and secure. It is also important to learn about the different bicycles, so they can choose the best one for their needs. The National Highway Traffic Safety Administration, as well as other government agencies, are working hard to make roads and streets safer for bicycles. This includes increasing the visibility of signs and signals, taking cyclists into account when engineering curves or grades during roadway construction, and developing bicycle education programs for all ages.

The geostationary operational environmental satellite (GOES) system provides vital meteorological and space weather data for North America. It is operated by the National Oceanic and Atmospheric Administration’s (NOAA) National Weather Service. GOES is the primary source of real-time images and data used by meteorologists to forecast weather and monitor severe storm development and movement. It also helps with atmospheric research, improving numerical weather prediction models, and monitoring the Earth’s surface, atmosphere, and ocean.

The GOES system comprises two satellites, one located in the east and the other in the west. They are positioned in geostationary orbit 35,790 kilometres (22,240 mi) above the Earth. This enables the satellites to regularly view the continental United States, the Pacific and Atlantic Oceans, Central and South America, southern Canada, and northern Africa.

GOES instruments observe the electromagnetic energy radiating from Earth, including visible light and thermal infrared radiation. They also observe the reflected radiation from the Sun off of Earth’s clouds and surface. Meteorologists use this information to identify cloud type and track storm movements. Surface reflectance from snow, ice, and light-colored sand is particularly noticeable on GOES visible image data, which reveals details about the structure of these materials. GOES instruments also sense solar X-rays and flares and measure the near-Earth solar-terrestrial electromagnetic environment, which is important for the operation of radio wave communication and navigation systems and to astronauts on the International Space Station and high altitude aviators.

Each GOES satellite has an Imager and a Sounder instrument, which work together to produce a variety of products. The Imager detects and measures infrared radiation from the atmosphere and surface, while the Sounder records vertical atmospheric temperature, moisture and ozone distribution. The Imager and Sounder are synchronized to provide a seamless, three-dimensional picture of the atmosphere.

The GOES-I and GOES-M series satellites have an additional feature: the S&R capability, which is capable of detecting distress signals from ships in the water. This function was first introduced on GOES-7 as a research/demonstration program, but it is now an operational service provided by the GOES-I-M series.

GOES data are also available to the general public through numerous websites and services. These sites are not considered official NOAA links and should be used for non-operational purposes.

In addition to providing imagery and data to the public, some GOES-I-M satellites have the ability to respond rapidly to specific requests for data from the National Weather Service. This is done through a system called “advanced event mode.” When the conditions required by the request are met, the satellite transmits data to the DCS in a different mode than normal. This mode can increase the frequency of data transmission, change the data format, or perform other functions. It is activated by a command sent from the NOAA Satellite Operations Control Center (SOC) in Suitland, Maryland. Currently, advanced event modes are active on GOES-13, GOES-15, and GOES-16.
