A bicycle is a human-powered machine that converts the energy of its rider into forward motion and kinetic energy to help it glide along a path. Whether used for recreation, transportation or sport, it is the most efficient machine yet devised to transform human energy into motion and transport people over long distances with minimal effort.

Bicycles have changed the way people work, play and live. They have reduced crowding in inner city tenements, allowed workers to commute to suburban jobs and ushered in the era of personal transportation. They have also helped to improve health by reducing dependence on cars and public transit.

It’s hard to say who first conceived of the idea for a two-wheeled bike with pedals and a handlebar, because a number of individuals independently invented similar machines in the 18th century. But in mid-1863 Pierre Lallement incorporated some of the earliest pedals in an improved version of his velocipede de pedale. This was the first bicycle that could be considered a bicycle in the modern sense of the word, and it was so successful that it quickly replaced the previous generation of bikes.

The basic components of most modern bicycles include a seat, pedals, gearing, wheels and brakes all mounted on a frame. The cyclist pushes the pedals to make the cranks turn, which in turn powers a chain that turns the back wheel of the bicycle to make it move forward. The front wheel is connected to the handlebar, so turning the handlebar swivels the front wheel that steers the bicycle.

Some modern bicycles have a seat tube that extends down from the bottom bracket to provide a place for the rider to sit. This type of bicycle is called a “drop bar.”

A few modern bicycles have hydraulic transmission systems, but the vast majority use a chain and derailleur to transfer power from the pedals to the rear wheel. Some use a shaft drive, and a few use a belt.

Most modern bicycles have pneumatic tires that are filled with air to cushion the ride and give traction over many types of surfaces. These tires require regular maintenance, including airing up and mending punctures, to maintain proper tire pressure and prevent flats. Some bicycles have puncture-resistant tires that incorporate one or more layers of Kevlar to prevent the penetration of sharp objects such as nails, tacks and glass shards.

The manufacture of bicycles has played a critical role in the development of metalworking techniques, especially those for making welded steel frames and components such as lugs. This early industrialization enabled skilled craftsmen to produce high-quality, durable bicycles. In recent years, however, lightweight aluminum alloys have largely replaced steel in the manufacture of bicycle components. In particular, aluminum welding technologies have gotten better, allowing for the production of frames and parts that are both stiff and light. This trend is expected to continue as manufacturing technology evolves. Some modern bicycles are even made of carbon fiber, which is very strong and weighs less than steel.

GOES provides advanced imagery and atmospheric measurements of Earth’s Western Hemisphere. It also tracks lightning, monitors space weather, and serves as an aid in predicting hazardous weather conditions.

Founded in 1974, the GOES series of satellites have become a vital part of NOAA’s observation and forecasting system. GOES-1 was the first of these satellites and used a visible/infrared spin-stabilized sensor to provide day and night observations of atmospheric conditions. It was one of NOAA’s most important satellites, providing critical information for meteorologists to make timely forecasts for severe storms, wildfires, volcanic eruptions, and other events.

The GOES satellites orbit in geosynchronous orbit, matching the speed of the Earth’s rotation around its equator. This allows the satellite to remain stationary in the sky above a point on the Earth’s surface, and the GOES-R series of satellites are expected to have an operational lifespan of seven years.

Each GOES satellite is equipped with two primary instruments: the Imager and Sounder. The Imager detects the visible and near-infrared radiation (radio energy) that is reflected off of the surface of the Earth and its atmosphere, and the Sounder provides real-time data on vertical atmospheric temperature and moisture profiles and ozone distribution. The satellites are also equipped with the X-ray Imager and the Space Environment Monitoring instrument (SEM) on some models of the satellites, which help NOAA meteorologists and other scientists understand the complex interaction between the Sun and its effects on our planet’s environment.

In addition to its observing capabilities, GOES-16 will be the first in the GOES-R series of satellites to be equipped with the Enhanced Visible and Infrared Sensor (EVIS). This new sensor will provide improved spatial resolution and faster temporal cadence for a variety of applications. For example, the EVIS will be able to track rapidly changing phenomena such as volcanic ash plumes much more quickly than previously possible. This improved capability will improve aviation safety by giving the National Weather Service’s forecast offices and Volcanic Ash Advisory Centers better insight into a potentially dangerous situation before airplanes encounter it.

The GOES-R series of satellites is operated by NOAA’s Satellite Operations Control Center in Suitland, Maryland. After the completion of on-orbit checkout, NOAA takes responsibility for command and control and data receipt/distribution. The GOES-R series of satellites includes the GOES-East and GOES-West spacecraft, which operate in geostationary orbit and cover North and South America. Each GOES-R satellite also includes the Advanced Baseline Imager, Extreme Ultraviolet and X-ray Irradiance Sensors, and Space Environment In-Situ Suite instruments. The Wallops Command and Data Acquisition Station on Wallops Island, Virginia serves as the primary telemetry, tracking, and command point for GOES-16.

When you hear the word nice, you may think of something pleasant or enjoyable. It could be a sunny day, a good meal or a person who makes you feel at ease. The meaning is more complex than just pleasing though. Nice can also mean respectful or proper. It can even be used to describe people and situations that meet ethical standards.

People who are genuinely nice care about others. They are genuinely interested in hearing what others have to say. They listen and are able to put themselves in the other person’s shoes. Nice people are warm and they help build group solidarity. They also like to give compliments to others.

These types of nice people are able to deal with adversity in a positive manner and they don’t let negative emotions consume them. They are able to find a silver lining in the darkest of clouds and they are optimistic about the future.

In terms of relationships, these people are able to forgive and forget. They have a strong sense of empathy and are able to empathize with the feelings of others. They know that it’s important to treat others as they would want to be treated, regardless of their beliefs and values.

The nice people in the world are able to be supportive of their friends and family members, even in the face of adversity. They are able to offer words of encouragement and they will go out of their way to do little things that will make their friends and family smile. These acts can be as simple as baking a cake for someone or sending a text to let them know they are thinking of them.

Interestingly, the word nice has quite an interesting history. It was originally a diminutive form of the Latin adjective nissa meaning “beautiful.” Over time it became associated with elegance, refinement and good taste. It was a highly desirable quality and it was considered to be a mark of social status. The word was also associated with sartorial perfection. It was common for people to refer to clothing as “nicely tailored.”

Nice has been a part of the English language for over 400 years and it is still in use today. It is a word that continues to evolve in its definition, just as other words do over time. It’s natural for words to change over time and this is especially true of words that have been around for a long time.

It’s important to remember that when we are being nice, it’s not for the sake of making ourselves look good, but rather, because we genuinely care about other people. It’s not easy to be nice all the time, but it is definitely something that everyone can strive for. The next time you see a person who is being nice, remember to thank them for what they are doing for other people. This will ensure that they continue to be kind in the future.

The term good is used in many different ways, depending on the context. In general, it is considered to be a favorable result or action: He did well on the test. The food was good.

It can also refer to moral qualities: He is a good person. The president is a good man. It can also refer to a feeling: I’m feeling good today.

In philosophy, the concept of goodness is a topic of extensive discussion. Since antiquity, philosophers have generally focused on two types of good: the prudentially good and the morally good.

However, it is difficult to distinguish between the concepts of good and the properties to which they refer. This difficulty stems from the fact that there are many different properties that can be attributed to an object or action and it is impossible to determine a priori which one(s) is the correct one(s).

Foot argues that this problem can be solved by defining what kind of property a concept refers to, but this view runs into problems of its own. For example, it is not clear whether a naturalist like Foot can analyze normative concepts in terms of their causal properties or whether such a characterization is necessary.

Some philosophers, such as Ewing, have attempted to solve the problem by separating out the notions of good and fittingness, arguing that this can clarify both the nature of goods and the way in which they are applied. Other philosophers, such as Peter Geach, have argued that the concept of good is intrinsically incomprehensible and that a theory of goodness must be a metaphysical, not a conceptual, theory.

The word good is also common as an adjective: It’s a good idea to invest in a savings account; it’s a good thing that we’re moving out of this apartment; I’m glad you came, but it’s not really good to have you here. Often, it’s used as an adverb after forms of do: He did good on the test; she sees well with her new glasses. This use is less common in formal writing and edited speech. In some contexts, it’s more appropriate to use the adverb well instead.

A bicycle (also called a bike, pedal cycle, or push-bike) is a human-powered, two-wheeled land vehicle that is powered by a rider sitting on it and pushing the pedals with their feet. It is the most efficient means yet devised for converting human energy into motion. Bicycles are used by millions of people around the world for transportation, recreation, exercise, and competition. The name comes from the prefix “bi-” meaning two, and the suffix “cycle” which refers to the wheels. It has a frame, two pedals, and a chain that connects the cranks to the front and rear wheels. It also has a set of handlebars that the rider grips with their hands.

The first bicycles were made of wood or steel wire, with the cranks attached directly to the front wheel. It was difficult to pedal and steer at the same time, because the rotational planes of the leg and the crank were not aligned. Later, a French mechanic named Pierre Lallement improved the velocipede de pedale by attaching the cranks to the non-steering rear wheel. This allowed the rider to push down on the pedals while turning the front wheel, and it also allowed for gearing to efficiently use the riders power.

Early bicycles were wildly popular, and many manufacturers began producing them in huge quantities. This led to a price war and oversupply, which drove sales down and caused many of the bicycle companies to go bankrupt. The surviving bicycle makers then focused on quality and design innovations to increase sales.

Today, bikes are made from carbon fiber, aluminum, titanium and steel, with each material having its own unique properties. The choice of material impacts the cost, weight, comfort and general “feel” of a bike.

Bike frames come in a variety of sizes and shapes to fit riders of all different sizes and styles. Besides frame size, other factors such as wheelbase and seat angle determine how the bike rides. Using these parameters, engineers and designers can tune a bike to achieve its intended purpose.

The most common bicycles are used for transport and recreation, but some are specialized for racing or other types of sports. Racing bikes are designed to be fast and light, while recreational bikes focus on comfort and durability. Some are equipped with special features such as suspension to absorb shock and allow the rider to sit in a more comfortable position. In addition, some are fitted with accessories such as baskets and carriers to transport items. Other accessories can be added to improve the performance of a bike, such as lights and reflectors, mirrors, and racks. There are even bikes with a built-in computer that can track the speed and distance of a ride. This information can be uploaded to a computer or smartphone for analysis and comparison with other cyclists in a race or on a training ride. This can help the rider to analyze their strengths and weaknesses and identify areas for improvement.

The National Oceanic and Atmospheric Administration (NOAA) operates a fleet of geosynchronous equatorial satellites known as GOES. Since their first launch in 1974, GOES satellites have been a fundamental element of the U.S. weather monitoring and forecasting system. Procurement, design and manufacture of GOES spacecraft are overseen by NASA. The GOES system provides real-time imagery and environmental data to the public and scientists worldwide.

GOES satellites are equipped with imager and sounder instruments, which collect information from the Earth’s atmosphere and surface. The Imager detects infrared and visible reflected solar energy, while the sounder collects meteorological parameters such as surface and cloud top temperature, humidity, vertical atmospheric temperature and moisture profiles and ozone distribution.

In addition to delivering critical weather information, GOES is capable of broadcasting distress signals from people, ships or aircraft to search and rescue ground stations. GOES spacecraft also support communications with the International Space Station, providing high-resolution images of Earth’s surface and near-Earth orbit.

The GOES-R series is the latest generation of NOAA’s geostationary operational environmental satellites (GOES). This new satellites will provide improved imagery and weather observation, including advanced detection of lightning activity, enhanced monitoring of atmospheric conditions and solar activities. It will also allow for better tracking of storms, which will improve weather forecasts and aid in search and rescue operations for people in peril.

GOES-R will be the first satellite series to feature the Advanced Baseline Imager (ABI), an instrument that provides three times more spectral channels, four times more resolution and five times faster scanning than previous GOES imaging systems. This will enable it to capture more images in less time, and at higher resolution, to give meteorologists more detail on rapidly evolving weather events. ABI is also able to detect solar flares that can disrupt communications, reduce navigational accuracy and affect satellites, high altitude airplanes and electricity power grids on Earth.

The GOES satellites are located in geosynchronous orbit 22,300 miles above the Earth’s equator, at a speed matching that of the Earth’s rotation. This keeps them in a fixed position in relation to the Earth’s surface. They can take pictures of the same area every 30 seconds and cover one hemisphere in a single pass.

The 14-satellite GOES fleet, which started with the launch of TIROS-1 in 1960 and ended with NOAA-19 on February 6, 2009, has a combined lifespan of 50 years. The GOES fleet of sensors has helped NOAA improve weather forecasting and helped save lives in the United States and around the world through enabling rescue efforts for stranded people, as well as aiding in disaster management and response. Each GOES satellite features two specialized instruments called the Imager and the Sounder, along with other supporting sensors such as a magnetometer, atmospheric sounder and radiometers. These satellites provide a continuous stream of images and data that can be accessed on the web through NOAA’s Data Access System, SPEDAS. A new GOES is launched every three years.

Nice is an adjective that means friendly, ingratiating, or conciliatory. It can also refer to something that is pleasing, gentle, or delicate: A nice supper, for example. The word has a long history, and its semantic evolution has been quite variable. It began as a negative term, derived from the Latin nescius (“ignorant, simple”) and became more and more positive through Middle English and into modern usage.

Nice people are genuinely kind, benevolent, and respectful. They often go out of their way to make others feel comfortable and at ease. This is true whether they are making small gestures like holding the door for someone or more substantial actions such as volunteering their time to help those in need. They treat others with respect and have a high level of self-esteem that allows them to be open and honest with those around them.

A person who is nice is generous with their time and resources. They are not only happy to give others the benefit of the doubt, but they actually enjoy helping and serving those in need. They can easily see the difference that their generosity makes in the lives of others.

They can sincerely congratulate others on their success and support them in their endeavors, even if they don’t share the same interests or values. This is a sign of a truly nice person who cares about others and wants to help them be the best version of themselves.

A nice person will listen to their friends and genuinely want to understand them. They may ask questions to better comprehend the story and are willing to hear their point of view, no matter how different it might be from their own. They are sympathetic and empathetic, and they can empathize with the emotional turmoil of others, which helps them to remain calm in difficult situations.

Nice people will never gossip or speak negatively about others, even in the privacy of their own homes. They have an unwavering sense of loyalty, which is reflected in their ability to keep a secret and trust others. They can empathize with those who are having a hard time and offer their support and guidance without judgment.

The act of being nice releases serotonin and oxytocin, which are natural mood-stabilizers that lower stress levels. Being nice also reduces anger and aggression, so it is an effective tool for reducing conflict in a workplace or in a relationship. It is also beneficial for maintaining one’s own mental and physical health, as it reduces the risk of depression, anxiety, and PTSD. For these reasons, the word nice has a positive connotation in all parts of the world. In fact, it has even become a global currency through the internet and other technological channels. The city of Nice, the capital of Alpes-Maritimes in southeastern France, is named for the pleasant weather and setting of the Mediterranean Sea. It is the largest and busiest port in France.

Good is a general term of positive evaluation, used in many different contexts:

‘Good’ can be contrasted with bad and with other terms of negative evaluation. The word is also associated with the concept of morality, and in particular teleological ethics.

The concept of good is central to philosophy, and has been the focus of extensive discussion since antiquity. In general, it has been conceived as that which lifts humans above the animal kingdom, and is therefore more than pleasure or pain, wealth or poverty, health or illness, virtue or vice. Aristotle, for example, developed an idea of the good life that focused on the development of reason in order to excel at what makes humans distinctly human.

Modern ethical theories often use the term good to refer to a general principle that guides an individual’s choices and actions. Such ideas include utilitarianism, deontological ethics, and ethical naturalism. Aristotle’s idea of the good life was influenced by both utilitarianism and hedonism. His emphasis on the development of the rational faculty was a precursor to utilitarian thinking.

For most of history, the notion of good has been linked to a sense of merit. The term is also used in a more neutral manner to express positive evaluation: ‘That’s all to the good,’ meaning that something is advantageous or desirable. Using the term in this way is common even in contemporary usage: ‘She did well on the test,’ or ‘He sees good with his new glasses.’

A variant of this notion of good is sometimes associated with virtue, particularly virtuous habits: ‘She has very good eating and sleeping habits.’ The term is also frequently used as an adjective after the verb feel: ‘He feels good after his operation.’ An old notion that it is improper to say “I feel good” in reference to one’s health still occasionally appears in print, perhaps reflecting a combination of an idea that good should be reserved to describe virtue and uncertainty about whether an adverb or an adjective should follow feel: Today, nearly everyone agrees that both good and well can predicate adjectives.

Other uses of the word good are related to concepts such as value and valuation. The idea of goods is also an important consideration in economics, especially for the purpose of establishing prices and regulating market behavior. In the context of a company, ‘good’ can also mean the quality of a product or service: ‘The service was good.’ In addition, ‘goods’ can be a synonym for raw materials, finished products, or services. For example, a person who works in the field of agriculture may be described as a goods trader. Similarly, an automobile manufacturer may produce vehicles as a goods business. Agricultural goods may be produced as commodities and sold in markets to other businesses, or they can be customized for specific purposes. For instance, a farmer may add crumb softeners to his or her wheat to make the crop more valuable to the buyer.

A bicycle is a two-wheeled vehicle with a frame, handlebars for steering and control, pedals for forward movement and brakes. It is used by millions of people around the world for transportation, fitness, exercise, racing and recreation. Riding a bike might seem easy to some, but it is actually an intricate process that involves the rider and the bicycle working together. There are many different types of bikes available to suit individual needs, from beginner-friendly tricycles and training wheels to high-performance race machines and everything in between.

A specialized bicycle designed for the purpose of competing in professional road, track or mountain bike races is known as a racing bicycle. These are often made from lightweight materials and have components like handlebars, seat post and cranks designed for maximum efficiency. Depending on the competition, there may be additional accessories such as a hydration system or electronic drivetrain.

Cycling provides a good cardio workout while improving endurance, strength and flexibility. It can also help reduce body fat and improve bone health. In addition to its physical benefits, it can be a time-efficient mode of transport as it can replace the need for driving a car or taking public transportation.

Health risks associated with cycling generally fall into three categories: traumatic (external) injuries; overuse injuries; and injuries or disorders caused by environmental exposure. The most common type of injury occurs when a person is struck by a moving or stationary object while riding a bike. Most of these accidents result in damage to the cyclist’s arms and legs, but head and neck injuries are also common.

Overuse injuries typically affect competitive cyclists or those who ride for several hours a day as part of their work. They can include wrist pain from gripping the handlebars; back, shoulder and neck pain from improper posture; knee pain from repetitive flexing of the joints; and saddle sores.

An increasing number of people are turning to cycling as a way to get around town and to work. Besides providing an opportunity to enjoy the outdoors, it can be a great form of exercise and a fun way to socialize with friends. However, it is important to understand the basic safety rules of riding a bicycle before beginning your journey on the road.

Frame size is one of the most important factors when choosing a bicycle. Compared to the wheels, which stay the same size on most bikes, frames come in various sizes and shapes. A frame that is too small can cause toe overlap, which happens when the rider’s foot rubs against the front wheel as he or she turns the bars.

Most bicycles use a steel alloy frame for its high strength and low weight, although higher-end models are often made from carbon fiber. Welding techniques have improved since the early days of bicycles, and aluminum alloys are now used in place of steel in many mid-range and high-end frames. There are even bicycles with titanium frames, which are lighter and stronger than steel but still stiff enough for race-level performance.

The Geostationary Operational Environmental Satellites, known as GOES, are critical to NOAA’s mission of providing the public with weather and other environmental data. These satellites circle 22,236 miles above Earth’s equator and maintain their positions over specific geographic regions, improving detection of environmental phenomena that directly impact public safety, property, and our nation’s economic health and prosperity.

The National Weather Service relies on GOES for continuous, reliable and high-quality weather observations to provide the information necessary to make the best decisions about people, property and infrastructure. The GOES-R Series of satellites will continue this important work, offering real-time imagery and meteorological data that are vital to the protection of life and property and the enhancement of the quality of life through the provision of accurate, timely and useful information and products.

GOES satellites contain instruments that measure Earth-emitted and reflected radiation, from which atmospheric temperature, wind speed, moisture and cloud cover can be determined. The satellites also track storm fronts, provide lightning observations, monitor the arctic atmosphere, and observe solar activity. They provide the information needed to support a variety of forecasting and monitoring activities, including severe weather watches and warnings, meteorological research and numerical weather prediction models, and environmental sensor design and development.

The Imager and Sounder instruments are the primary instruments on the GOES satellites. The Imager provides a view of the Earth’s surface and its clouds, while the Sounder monitors atmospheric motions and provides meteorological parameters such as pressure, temperature, winds and water vapor. The GOES satellites also contain other instrument packages such as the Space Environment Monitor (SEM) which is used to identify and monitor solar activity that may potentially threaten space-borne or ground-based assets and the Solar X-ray Imager (SXI).

All of the GOES satellites are built by Lockheed Martin for NOAA, under contract with NASA. The GOES-13 and -16 satellites carry the COSPAS-SARSAT system, which detects the signals sent by 406 MHz emergency beacons on airplanes, ships and individuals during searches and rescue missions and relays this information to rescuers. GOES-13 and -16 are also equipped with the Space Environment Monitoring (SEM) package developed by NOAA’s Space Environment Center, in Boulder, Colorado.

The GOES satellites are controlled by NOAA’s Satellite Operations Control Center in Suitland, Maryland. During significant events or emergencies, a GOES satellite’s regular schedule can be altered to monitor more regions or provide special observations. The GOES-15 satellite has a solar array with eight 16-panels, and is designed to be the first in a new generation of GOES satellites that will have an operational lifespan of ten years.
