The History of the Bicycle

A bicycle is a two-wheeled human-powered vehicle that is propelled by pedals and steered with handlebars. It is widely used for recreation, transport and exercise. It is the most efficient means of human transport for its size, and it can carry a rider at three times the speed of walking.

The bicycle was first developed in the early 19th century, although historians disagree about its exact origin. It is generally accepted that the first verifiable claim for a practically usable bicycle dates to 1817. It was designed by Karl von Drais Sauerbronn, a civil servant to the Grand Duke of Baden in Germany. He patented his Laufmaschine (German for “running machine”) in 1818, which was known as a draisine or velocipede (French for bicycle). It was also called a hobby horse, dandy horse, or dandy bike.

While there are many claims of who invented the bicycle, no individual can be credited with its invention as it was the result of the efforts of a number of people. Leonardo da Vinci is credited with drawing a bicycle in 1492, but the sketch was later determined to be a forgery. Da Vinci did, however, draw other, similar vehicles in his Codex Atlanticus, including a device that could be ridden like a bike but was not considered an ancestor of the modern bicycle.

Bicycles became a popular means of transportation around the world after being introduced in Europe. They allowed urban dwellers to commute from their crowded inner-city tenements to more spacious suburban dwellings, and they helped to relieve the burden on the city’s overtaxed horse populations. They provided a convenient way to travel for leisure, as they were faster and more energy efficient than walking.

By the turn of the 20th century, bicycles were commonplace in many areas, providing an affordable means of transport for millions of people. They reduced crowding on public transit and allowed commuters to save money by eliminating the need for taxis. They also enabled families to take vacations away from work and allowed people to visit relatives in far-away cities.

As technology improved, bicycles became lighter and more efficient, making them a popular mode of transportation. The development of alloy metals and hollow-section steel frames reduced weight and made the bikes easier to maneuver, while new tire types increased traction and efficiency. The introduction of the derailleur gear system and the chain drive (originated by Englishman James Starley) enabled bicycles to be driven at lower speeds without using cranks.

Modern bicycles come with a variety of accessories to enhance riding comfort and safety, including seats and handlebars that adjust for different riders, frame-mounted racks for transporting luggage and equipment, fenders to protect the biker and pedestrian from road debris, and lights and reflectors for use at night or in poor visibility. Bicyclists must wear a helmet and appropriate clothing to be safe on the road. Drivers should yield to cyclists and be extra vigilant when turning at intersections, driveways and parking lots.

GOES-R – The Next Generation of Earth Observing Satellites

The GOES satellite system provides a continuous flow of environmental data used for weather forecasting, severe storm tracking and other meteorological research. It also enables the relay of distress signals from aircraft, ships and people in need of assistance to Search and Rescue (S&R) teams.

A GOES satellite is in geostationary orbit, 22,236 miles above Earth’s equator. This allows it to hover over the same geographic region of the Earth at all times, delivering images and data to NOAA’s National Weather Service offices in real time.

The satellites are equipped with a pair of instruments: an Imager and a Sounder. Both of these instruments monitor the atmosphere in different ways: the Imager senses radiances in a broadband visible and several infrared channels, while the Sounder measures atmospheric temperature and moisture.

During the day, the Imager will detect radiation that is reflected off of cloud and ground surfaces. This includes sunlight, but also the electromagnetic radiation emitted by lightning, nitric oxide and other air pollutants. These radiation signals are recorded by the instrument and transmitted to the Earth Data Acquisition System in Suitland, Maryland. The information is processed and displayed as imagery on a NOAA website or in a weather application.

At night, the Sounder will sense radio waves emitted by the Earth’s surface and atmosphere. These signals are recorded by the instrument and transmitted to a data processing center in Suitland, Maryland, where they are used for analysis of a variety of atmospheric phenomena, including severe storms and hurricanes. The Sounder also tracks the Sun’s solar wind and its impacts on the Earth’s electromagnetic environment.

In addition to the two main payload instruments, GOES satellites also fly the Space Environment Monitor (SEM) instrument package from NOAA’s Space Environment Center in Boulder, Colorado. This instrument measures the near-Earth solar-terrestrial electromagnetic field using an array of three boom-mounted sensors.

GOES-R is the next generation of NOAA’s geostationary operational environmental satellites. The program includes the development and deployment of seven new satellites, a robust ground system to receive the enormous amount of data from these satellites and deliver it to customers, as well as a suite of advanced science capabilities to support improved weather prediction.

Aerospace helped ensure GOES-R was ready to meet the needs of its users during the design, integration and launch phases by establishing and leading a first-of-its-kind embedded team that actively managed the production of all GOES-R data products. The team also designed and built the GEOS-R data processing and distribution system and the associated ground infrastructure.

For the GOES-R Level 1b and most Level 2 products, geographic information is stored in the GOES-R data files as horizontal (x) and vertical (y) scan angle coordinates. This information is required to correctly map eddy covariance tower locations onto the ABI fixed grid and obtain ABI observations. Using these coordinates, it is possible to convert the tower geodetic latitude and longitude values from the corresponding NOAA/NCEP station file into ABI scanning angles.

What Makes a Nice Person?

A nice person is warm, friendly, and helpful to others. Being nice is often an inherent quality and some people have a natural gift for kindness, compassion, and empathy. However, for others, being nice can be challenging and may require extra effort. Being nice can bring you joy, but it can also come with its own set of challenges. It’s important to know what makes someone a genuinely kind person and how to identify those traits in other people.

A genuinely nice person is honest and transparent with others, even if they are being hurt by someone else. They will own up to a mistake and try to make it right. They are fair and always choose fairness over personal gain, especially in situations involving their loved ones. Being nice means making other people feel good, and it’s a good thing to do for other people because it gives them the sense of fulfillment and happiness that they deserve.

Being nice is a great way to make friends and build strong relationships. It can also help reduce stress levels, as acts of kindness increase serotonin and oxytocin, which boost your mood and feelings of connection. In fact, one study found that if you are socially anxious, doing small acts of kindness can actually help you overcome your fear! The sense of joy you get from making other people happy is addictive and can help you connect with other people in a deep and meaningful way.

Whether you are a naturally nice person or someone who needs to work on being nice, it is important to remember that being nice can be used as a form of manipulation. For example, if you are a nice person who regularly holds doors open for strangers, you may find yourself being taken advantage of by people who see it as a way to accelerate their relationship with you. It’s a good idea to follow the 3-strikes rule: if someone repeatedly misbehaves, you may need to stop being so nice and give them a lesson in their behavior.

Nice is a beautiful city in southern France, with a warm Mediterranean climate and beautiful beaches. Its clear air and soft light have attracted many notable painters, including Marc Chagall, Henri Matisse, and Niki de Saint Phalle. The city has a vibrant culture and is home to several museums, including the Musee Matisse and the Musee des Beaux-Arts. The city was also a favorite spot of writer Friedrich Nietzsche, who spent six winters here and wrote his seminal work Thus Spoke Zarathustra. It is now a major center for tourism, finance, and high technology. In addition to its sandy beaches and stunning views, Nice is also known for its nightlife and gastronomy. There are numerous clubs, bars, and restaurants in the city that attract locals and tourists alike. The city is also well-known for its annual jazz festival and the Nice International Film Festival.

The Importance of Being Good

The good are people who obey rules, act in a socially correct manner, and generally behave well. This word is often used in reference to moral standards or religious beliefs. In this sense, good can also refer to things that are useful or beneficial. For example, it is a good idea to exercise regularly for your health, and it is a good thing that many people have access to electricity. The word good can also be used to describe a person’s personality or temperament. For instance, someone who is good-natured is friendly and helpful to others.

When someone has a good disposition, they are able to see the positive aspects of a situation. This ability to find the good in every circumstance can be a valuable skill in life. For example, if you are facing a difficult challenge at work, it can help to focus on the good qualities of the people involved in the project. This can give you the courage to move forward even if the outcome may be uncertain.

One of the keys to success in any field is being able to read your audience. This includes knowing what they are interested in and how to best communicate with them. In addition, it is important to use proper spelling, grammar, and punctuation. A good writer is a skilled craftsman who is always improving their writing skills. They have a deep adoration for language in all its forms. They are able to expand their vocabulary, experiment with meter and rhythm, and use rhyme and alliteration. Ultimately, they are able to transform their ideas into engaging and compelling narratives that will capture the attention of readers.

Whether you are working in the classroom, in business, or on a construction site, having good communication skills is essential. Good communication requires listening carefully to other people’s viewpoints and being able to explain your own points of view in a clear and convincing manner. Good listeners are receptive to the opinions of other people and are willing to try new ideas. Good listeners are also able to empathize with other people’s problems and emotions.

In a business environment, having good communication can increase productivity and reduce employee turnover. Managers who are good communicators inspire their employees to be creative and take risks in the workplace. This is because managers are able to convey their trust in their employees, and this leads to open dialogue and collaboration.

The Basics of a Bicycle

A bicycle is a human-powered two-wheeled vehicle that provides both transportation and recreation. Bicycles have been around for over 100 years, and their development continues to be a source of innovation and excitement. The basic components common to most bicycles include a seat, pedals, gearing, and handlebar. The rider’s feet push on the pedals, which in turn drive a crank that turns a chain, which in turn drives the back wheel of the bicycle to propel it forward. The front wheel is connected to the handlebar, so turning the handlebars swivels the front wheel to steer the bike.

Cycling is an excellent form of exercise. It burns calories, strengthens muscles, and improves cardiovascular health. It is also a fun and relaxing way to spend time outdoors. However, cycling should not be performed to the point of exhaustion, and it is important to allow the body to recover from intense exertion.

Unlike motor vehicles, bicycles do not emit pollution and are easy to maintain. They are also relatively inexpensive compared to automobiles. As a result, they are an attractive mode of transportation for people of all income levels. A growing number of cities and states are creating safe bicycle infrastructure, making it safer and easier for people to get around on bikes.

Bicycles are very effective at transporting goods over long distances. They can carry a load up to 150 pounds (68 kg), and they are capable of traveling at up to 20 miles per hour (32.2 km/h). In addition, they can be used for recreational riding, racing, and exercise.

Since the early twentieth century, the bicycle has become a symbol of freedom and individuality. It allowed people to escape from cramped inner-city tenements and commute to work in the suburbs, and it reduced dependence on horses for both transportation and labor. During the summer of 1897, members of the United States Army’s 25th Regiment, the Buffalo Soldiers, traveled more than 1,900 miles on their bicycles to demonstrate the military value of these machines over rough terrain.

In many parts of the world, bicycles are the primary mode of transport for short-distance travel. They are widely used in urban areas to reduce traffic congestion and air pollution, as well as for tourism and fitness. In some places, laws require cyclists to wear a helmet and use reflectors on their clothing and bicycles. Some cyclists choose to add auxiliary saddles or pegs to the frame to transport cargo, children, or equipment. In other cases, a bicycle may be hitched to a trailer or truck for delivery of goods. In some countries, postal workers deliver mail on bicycles. They usually store their letters in front baskets, panniers, or trailers. Many cities also offer bike-sharing programs, where residents can borrow bicycles for short periods of time. In the United States, there are over 200 public and private bike-sharing systems. In these systems, the riders typically pay a small fee to rent a bicycle.

New Upgrades to the GOES Satellites

The GOES satellite system has served NOAA for 40 years and continues to help forecasters predict severe weather events, detect and track fires, as well as provide valuable scientific data on Earth’s atmosphere, oceans, and climate. This data is vital to a wide range of operations and activities, including search and rescue efforts, radio wave communication and navigation systems, electric power grids, and even the missions of astronauts aboard the Space Station, high-altitude aviators and geophysical explorers on land.

NOAA’s National Environmental Satellite, Data and Information Service builds and launches the GOES series of satellites and operates them for the benefit of all Americans. GOES is one of NOAA’s most important programs for the public, providing information about weather and solar activity in real time.

A new version of the GOES Imager will be flying on GOES-18. This upgrade, known as GOES-18 Imager Block 1 (GBIB) upgrades the instrument’s spatial and temporal imaging capabilities by more than double, and improves its ability to capture meteorological phenomena like clouds and fog.

The upgraded GBIB will also be able to take pictures at a rate of 30 Mesoscale images and one Full Disk image every 15 minutes. This will allow the satellite to keep an eye on a large area of the country and can be used to identify changes in atmospheric conditions that affect people, animals and infrastructure.

GOES-18 also has a new tool for studying seasonal changes in the Amazon rainforest. While previous studies have used polar-orbiting satellites that fly over the region only once or twice per day, the GOES-18 Advanced Baseline Imager (ABI) is in geostationary orbit and can observe the Amazon at regular intervals for entire days. This can help scientists develop a more nuanced view of the carbon cycle and better understand how climate change might impact the forest’s productivity.

In other news, GOES-R is making great progress as it prepares for launch. The GOES-R mission rehearsals are stepping up to simulate critical post-launch activities, like spacecraft separation from the rocket and instrument activations. All GOES-S instruments, including EXIS, SUVI and the ABI have been delivered for integration with the satellite, and a system module that is the brains of the spacecraft has been completed and flown in to Lockheed Martin’s Littleton facility for mating with the sun-pointing platform.

Also in preparation for GOES-R’s launch, the CCOR instrument is being finalized for integration with the spacecraft. CCOR is a follow-on to the Lasco Coronagraph for Space Weather (LASCO) instrument that currently flys on GOES-13. CCOR is designed to be a single instrument that can simultaneously provide CME (coronal mass ejection) imagery for both the Earth-sun line and the sun’s surface, providing continuity of crucial CME observations for NOAA.

The Dangers of Being Too Nice

Nice is a word with many meanings—it can be gentle and friendly, ingratiating or conciliatory. It can also be mean, lewd, or wanton. But whatever the definition, it is always good to be nice.

Being a nice person obviously benefits those around you, but it can also help you feel happier and more connected. In fact, a recent study found that people reported greater happiness when engaging in kind behaviors than when they were focused on things like money and physical attractiveness.

People who are naturally nice are usually very empathetic, meaning they can put themselves in other people’s shoes and understand their feelings and experiences. This empathy is a powerful trait because it allows them to connect with others on a deeper level and provide genuine support and comfort.

But while being nice is a positive characteristic, it can have some negative side effects if it becomes more important than authenticity and honesty. This is particularly true if being nice comes at the expense of one’s own needs. When a person is constantly stuffing down their true thoughts and emotions, they can reach a breaking point. These repressed feelings can manifest themselves in a variety of ways, from outbursts of anger to irritability.

A big problem with being too nice is that it can create false facades and make people think they are better than they actually are. For example, when someone is too nice in the workplace, they may be seen as less ambitious or competent than their peers. They may also appear to be a pushover because they don’t stand up for themselves or express their opinions.

Another downside of being too nice is that it can make you more likely to get taken advantage of by those who are less benevolent. It can be easy to fall prey to the behavior of narcissists who only see kindness as a means to gain approval and attention. People who are naturally nice often have a warm and welcoming personality, which makes them ideal candidates for being narcissistic manipulators.

If you’re a naturally nice person, it’s a good idea to work on being more authentic and honest while still engaging in small acts of kindness. This can include things like passing the salt without being asked, offering to let a stranger hang their coat on your barstool, or letting someone merge in front of you. By making being nice a habit, you can become more intentional about how and when you act in a kind way—and it will also make the bigger gestures feel more natural and genuine.

Aside from being a great city for shopping and dining, Nice is home to two of the world’s greatest painters. The Musee Matisse, located in a 17th-century villa in the Cimiez neighborhood, features the largest collection of works by Henri Matisse. The museum is just steps away from the Arenes de Cimiez, a public park featuring Roman ruins including an amphitheater and bath complex.

What is a Good Article?

A good article is an article that is well written and has been published on a reputable website. It is a piece of content that captures the attention of the reader and keeps them engaged throughout the article. The quality of an article is determined by a number of factors, including language, vocabulary and the ability to maintain the reader’s interest. It is also important that the article is well structured and logically sequenced.

A common use of the word good is as an adjective describing something that is pleasant or satisfying: Good, Tom has finally arrived!

The word good is also used as an adverb to modify verbs such as taste, smell, look, feel, and appear: Everything tastes good, the biscuits are really good. I’m feeling pretty good this morning, I think I’ll be able to do the task today.

Good is a concept in ethics, morality, philosophy, and religion that describes the opposite of evil. It is an essential part of the Abrahamic religions’ teachings. It is also the central theme of a number of modern philosophical and religious traditions. In the Bible, the word good is used in many different ways:

For example, the Hebrew word “mahto” () can be translated as ‘fair’ or’meritorious’; it is also used to mean ‘favorable’ or’suitable’ (Mt 18:8 f; Mr 9:43; Lu 5:39). The Greek word ‘eudokios’ () has similar meanings and is often translated as ‘good’.

Writing a good article requires a great deal of skill and practice. It should contain a balanced mix of facts and opinions, and be clear, concise, and accurate. The author should take into account the target audience and write in a style that is appropriate for that audience. The use of a variety of sentence lengths and structures will also help to keep the reader’s attention.

The Basics of Buying a Bicycle

A bicycle is a human-powered, single-track vehicle with two wheels attached to a frame, one behind the other. It is also known as a pedal bike, pushbike or cycle. People who ride bikes are called cyclists. Bicycles are used in many sports and forms of transportation, and have spawned numerous related industries and subcultures. The most important part of a bicycle is the frame, which supports the weight of the rider and holds the cranks, chain and other components. The bicycle frame is usually made from steel or aluminum, though titanium and carbon are becoming increasingly popular.

The first bicycles, which were called velocipede de pedale or dandy horses, were developed in the early 1800s. The earliest version, invented by German nobleman Karl von Drais, was a clunky wooden beam with no pedals or tires and a mechanism for propulsion that involved using a lever to push off the ground.

During the next few decades, engineers made significant improvements to bicycles. The cranks were moved from the axle to the frame, and the front wheel was lowered, making them easier to balance. The chain drive was added, and the modern bicycle became more streamlined and efficient.

Most people use their bikes to get around, but they are also a common mode of transport for racing and exercise. Almost 100 million bikes are produced every year, and they are used on all of the world’s continents. Bicycles are a critical component of the global economy, providing jobs in manufacturing and agriculture, and conferring benefits on other industries such as industrial design, health and social policy.

In the late 19th and early 20th centuries, manufacturers developed specialized bicycles to suit particular markets. For example, racing bicycles have a rigid frame and thin tires for maximum speed. Commuter and recreational bicycles are designed to be comfortable for long rides and can accommodate racks, fenders, and other accessories for practicality.

As a result, there are several types of bicycles on the market, from lightweight and high-performance road bikes to mountain bikes that can handle rugged terrain. There are also hybrids that are designed to be versatile and commuter bikes that can withstand the rigors of everyday riding.

To choose the best bike for you, consider the type of riding you plan to do and where you will be doing it. Then, think about your body and comfort level. The right bike can make all the difference in your biking experience.

To begin, you should find a good spot to stand on your bike. Position your feet so that your right foot is on the bottom of the pedal, and the left is on top. Then, bend down on the bike and keep your core tight as you shift your weight forward over the seat and handlebars. The movement should feel natural and effortless, like you are gliding over the surface of a smooth road. When you are seated in the saddle, your legs should be straight out in front of you with your knees slightly bent. This allows you to easily reach the hand holds while maintaining your balance and static control.

GOES Satellites and Their Missions

Since 1975, the geostationary weather satellites in NOAA’s GOES (Geostationary Operational Environmental Satellite) program have provided continuous imagery and data on atmospheric conditions. This data has led to better severe storm tracking and forecasting, improved understanding of Earth’s atmosphere, ocean and climate and helped in the search-and-rescue of people in distress.

GOES’ mission is a joint NOAA and NASA project that builds, launches and operates the spacecraft and ground system elements that provide a continuous stream of environmental data for use by forecasters, meteorologists, scientists, engineers and others. The National Weather Service and the Meteorological Services of Canada use the GOES spacecraft and their data for severe storm tracking, monitoring atmospheric conditions and providing warnings to the public. NOAA scientists use the data to understand the role of the Sun and its effects on Earth’s environment and weather systems.

Each GOES satellite is equipped with a variety of instruments that gather and analyze information about the atmosphere. The Imagers on GOES satellites record visible and infrared radiation that is scattered or reflected by clouds, water vapor and the ground surface. The Sounders measure the motion of the atmosphere, including wind speed and direction, cloud top temperatures, vertical temperature and moisture profiles, turbulence, fog, snow and ocean currents. GOES also collects information from free-floating balloons, buoys and remote automatic weather stations located around the world.

The first GOES spacecraft, GOES-1, was launched in 1975 and provided the first direct, real-time look at atmospheric conditions from a fixed orbit. Using the Visible/Infrared Spin Scan Radiometer, GOES-1 provided day and night images of clouds and cloud tops, surface temperatures and winds.

GOES instruments have regular schedules for scanning the Earth. For example, GOES East instruments perform a North America scan, a Northern Hemisphere scan and a full disk scan on a routine basis. The instrument schedules can be adjusted during significant weather events and for scientific research purposes.

A 10-minute full disk scan on GOES can allow NWS Weather Forecast Offices and Volcanic Ash Advisory Centers to monitor hazardous weather conditions more rapidly. For example, when volcanic ash clouds move quickly across the atmosphere, they can be difficult to track with traditional imaging capabilities. The faster temporal cadence of a 10-minute full disk scan can help reduce the risk of aviation accidents caused by these hazards.

In addition, GOES-13 and -14 carry an instrument that detects signals transmitted from 406 MHz emergency beacons carried by aircraft, ocean-going vessels or individuals in distress. These distress signals are detected and relayed to ground stations that are part of the COSPAS-SARSAT international system of search and rescue satellite-aided tracking. This capability helps with the search and rescue of people in distress and can also be used to locate ships in distress. This is an important safety function, especially during periods of frequent shipping traffic through the busy waters surrounding the Netherlands.
