First Try write about BCH
The Bitcoin Cash or ***BCH*** is the result of hard fork`(Forking is to take the source code from an open source software program and develop an entirely new program)`in **blockchain** technology.It is an **altcoin** verson of the Bitcoin cryptocurrency. Previously, Bitcoin’s 1**MB** limitation caused transaction delays, so Bitcoin Cash increased the potential **block** size.
The Bitcoin network is currently capable of proessing seven transactions per second, whereas Bitcoin Cash can process around 116 transactions per second. It enables a great number of transactions and help the cryptocurrency scale as it grew and competed with more traditional cryptocurrency platforms.After its creation, BCh quickly became the 3rd most successful cryptocurrency, following Bitcoin and Etherium.
BCH Structure And size importance
Bitcoin Cash was created and designed to pack 32MB of data into each block and to process 116 transactions per second on average. While transaction speed is greatly increased with BCH, the larger block size also requires more processing power for nodes to support the blockchain network.
So why not just make the blocks much bigger — say 100MB? That would make the network much faster, but extremely restrictive in terms of who could run a node, verify new blocks on the blockchain, and support the network. The debate about block size essentially boils down to speed versus decentralization and which of the two is more desirable.
Large institutions, organizations, or BCH-businesses are able to consolidate the type of processing power required for large block sizes. In contrast, it would be much more difficult for individuals to amass sufficient processing power to handle large blocks. This discrepancy threatens to create an oligopoly `(where processing power is consolidated in the hands of a few key players)`, which ultimately endangers the decentralized nature of the blockchain. A healthy mix of decentralized, distributed, independent verification is what makes the blockchain secure and reliable so, in a nutshell, more nodes equals greater network security.
Work of BCH
BCH transactions are quick enough that you could make a grab-and-go retail purchase with BCH (like a cup of coffee). But what if you were making a large purchase?( such as a car or a house). You could opt for a slower, more secure cryptocurrency like BTC.
BCH and BTC, therefore, fulfill different roles. Not every cryptocurrency is a store of value, and not every cryptocurrency needs to process data quickly to function like a credit card transaction. It makes sense to use different tools for different tasks — much like using a credit card for restaurant dining and a bank transfer to buy a house.
Ultimately, BCH is faster and features lower processing fees than BTC, but is still used less frequently as everyday cryptocurrency payments have yet to be widely adopted. Over time, many believe that greater awareness and complementary technological improvements and innovations will pave the way for BCH to serve as a leader in cryptocurrency payments.

Sleep and Light
When we are asleep, our brain stores memories and information. It removes harmful elements from the body and fixes everything so that the body can function properly again after waking up. A little lack of sleep also affects our well-being a lot. There are many people who break down if they do not sleep one night. If we do not sleep for three nights, our performance will be lower than normal. According to one study, the effects of excessive alcohol consumption are similar to those of a person who stays awake for 16 to 19 hours in a row. The level of damage increases with time. Studies have shown that not sleeping for 11 days in a row has a serious effect on behavior and work. Attention and short time memory are impaired, hallucinations occur, and even brain distortion occurs.
Scientists have always insisted on getting enough sleep. The importance of light in sleep may be somewhat hidden.The reason why light is important is that it determines our body clock with the help of special light sensors in our eyes. The human eye detects light and darkness in any environment and determines the circadian rhythm in the body or the physical activity on and off after 24 hours. When someone's eyes are severely damaged, their body clock is also damaged, resulting in trouble sleeping. Even when in the dark for 24 hours or without exposure to light, the human body clock changes slightly. Research says that in that case half an hour or an hour can go by. The best example of the effect of light on sleep is jet lag. When you board a plane and go to a country in a different time zone, you will see that your body is slowly adapting to the time zone of that country. After a few days you will see that you can sleep at night, you can stay awake during the day.
By 1800, most of the world's people were working outside. As a result, they were in direct contact with light. In today's offices, people do not understand where the sun sets and when the sun sets. Because most people's workplaces are now inside the building. Outside jobs, such as fishing or farming, account for about 1 percent of all jobs in the United States. Since we have been deprived of sunlight for a long time, it is affecting our sleep but also our well-being. Sunlight is very important for our body. The amount of light needed may vary from person to person, but there is no doubt that the lighting system inside most buildings is not sufficient for our body.Due to lack of adequate sunlight, 2-6% of people in Europe suffer from a type of depression called seasonal affective disorder. There are many more areas where the lack of adequate lighting has caused many problems.
Working at night has quite a deadly long-term effect. Worst of all, it can reduce life expectancy by up to six years. Working night shifts Lighting is more serious for those who work at night. They have to work when their body wants to sleep. At that time the body does not want to exercise any kind of head or be careful but that is what has to be done. Those who work at night may try to make up for the lack of sleep at night by getting a little sleep during the day, but that is not enough. Because they usually sleep for a short time during the day and the sleep is not so deep.
They fall asleep when they are supposed to be awake, when they are supposed to be asleep, and because of this their health is severely damaged. The temporary effects of working at night are not being able to understand data properly, not being able to remember, and some behavioral abnormalities. Working at night has quite a deadly long-term effect. Worst of all, it can reduce life expectancy by up to six years. 98% of people who work night shifts fail to meet their expectations at work. No matter how many years they work. They cannot change their physiology. No matter how much light there is in the office, it is never equal to daylight. Normal daylight is 250 times brighter than artificial office light.When they go home after the night shift, their bodies come in contact with the morning light. This light sends a signal to their bodies that it is time to wake up. A Harvard study found that many people who work night shifts become nocturnal. They do not want to go out in the light of day. But for most people this is not a real solution.
Most nursing homes do not receive adequate sunlight. Most homes have light fixtures inside. As a result, residents are deprived of adequate sunlight. It is very common for the residents of these nursing homes to have sleep problems. A Dutch study found that bedrooms in nursing homes were kept dark and adequate sunlight was available in the rest of the area. As a result, residents have less time to sleep during the day and more time to sleep at night. Their mental capacity and overall health are improved.Lack of light does not depend only on the amount of light. Time is also involved in this. The soft light of the evening delays our body clock so it is too late to wake up the next morning. The light in the morning brings the body clock forward, making it possible to get up early in the morning. It was not a problem when people were working outside. The evening light would delay the sleep, the morning light would advance that time.
But now very few people come in contact with both morning and evening light. A good example is university students who start the day a little late in the morning and stay out till evening. Evening light slows down their body clock. That means they sleep late and wake up late. Hormonal changes before puberty and adulthood consolidate this, causing the body clock to be delayed by about two hours. As much as there is talk of smoking, drinking, or the harmful effects of unprotected sex, there is little discussion of the need for sleep and the role of light.
People could be more aware of this if there was enough talk about sleep. Adequate lighting, careful exposure to daylight and evening light. Policy makers could also set working hours, classes at educational institutions, and examinations. The less you can come in contact with light before going to sleep and the more you can stay in the morning light, the better sleep you will have. And be able to sleep at the same time.
Light pollution
We expect light. Without light, there would be no civilization. This fauna would not have been born. That is why we call the sun that pierces the chest of darkness the 'Lord of the World'. How much talk about light, how many adjectives! Literature and songs have been written about him. However, when that light becomes the cause of pollution, it seems to be a problem. Yes, the dictionary of pollution includes 'light pollution' or 'light pollution'. Almost the whole world is being polluted by this pollution. Our district East Burdwan is no exception. From the light of the lighthouse outside the house to the intense halogen light, the colorful neon light is making the night dark. In fact, we do not understand the importance of darkness. In addition to light, the fact that darkness is also essential for this ecosystem probably does not occur to us.
In fact, it started from the time I learned to light that fire. Learning to light a fire is one of the most important events in the history of human civilization. That fire carried the people forward, but, in that night light, the wild animals, the birds got into trouble. That light a few million years ago has now multiplied many times over. Wild people have been civilized. Therefore, the interests of business and self-promotion have become bigger than their own survival. From cities, small towns to villages পর artificial light is burning from sunset to sunrise. And in the developed countries of the world, this light is many times more. A study by a university in Italy found that two-thirds of the world's people do not understand the light of nature at night. The reason is the abundance of artificial light.
Experts have categorized light pollution into several categories — light trespass, over-illumination, light clutter, and so on.
When a bright light on the side causes discomfort to others, it is called 'light trespass'. For example, when a light on the street or outside enters the house through the glass window of another's house, it is called 'light tracepass'. ‘Over-illumination’ pollution causes light pollution over a wide area in very bright light. In the case of ‘light clutter’ pollution, a huge variety of colored lights confuse and mislead people. An example of this can be seen in the city of Las Vegas, USA. But it is good to know that the night sky is not completely black. This space is full of cosmic soft light. According to scientists, the night sky is about 40 times brighter and brighter during the full moon than the new moon.Artificial satellite images are usually analyzed and measured and measured with the help of other mathematical formulas. As of 2012-13, the sky in Hong Kong was the brightest. Singapore took this place in 2016. A few years ago in Paris a few years ago, almost all the lights in the city were turned off for a while in order to reduce the use of conventional energy that was rapidly running out and to get some return to the fog of the night. Some cities in India also participated in this work in Paris. Dear Burdwan was not left out either. In this way, if self-awareness is increased, light pollution will come under control.
Animals, including humans, have a 'biological clock'. With the help of which animals can understand the difference between day and night. As a result of light pollution, it has started to deteriorate. Sleep is disrupted. This insomnia has an effect on diet and reproduction. As a result, scientists fear the extinction of various animals in the near future. What happens to humans? Experts say that when the sun's light goes out, the hormone called 'melatonin' in the blood increases in the human body in the dark. Which is responsible for our sleep. Beta endorphins are released during sleep which act as a normal pain killer. Proper sleep determines the amount of insulin in the body. But as a result of light pollution, diseases like insomnia, diabetes and heart disease are on the rise. According to The New York Academy of Sciences, light pollution also indirectly causes diseases such as cancer.
The International Dark Sky Association was formed in 1986 to control light pollution. They are still carrying out various awareness programs. America also has anti-light pollution laws. This law imposes various restrictions on the use of unwanted lighting. There is also a system of punishment if necessary. The National Park Service's Natural Sound and Night Skies Division is also exploring the skies of various national parks and sanctuaries.Extremely bright LED light is associated with magical neon lighting. There are lights in various parks and gardens. But the problem is that sometimes the lights in all those places are not turned off on time. And all this light is having an effect on animals, especially birds. Such is the claim of scientists. Large lights are lit in the coastal areas of Damodar throughout the night to extract sand. Environmentalists claim that this is affecting the ecosystem in the areas adjacent to Damodar. So it is very important to be aware of controlling the use of light.
Telepathy
Pablo Picasso has a saying, “Everything you can imagine is real”!
If only people could understand how huge the power of human mind is! The artist Leonardo da Vinci, famous for his paintings of the Mona Lisa, once painted a model of an airplane. You would be surprised to know that he was four hundred years ahead of his time. Because, more than four hundred years after the drawing of this picture, the true airplane was discovered. I used to be in a bad mood whenever I saw a movie about robots. What all the instruments are moving, fighting with people. What makes unreal and cannabis things people think! Surprisingly, the robot is alive now.
I basically want to talk about telepathy. Telepathy is a matter of the mind. There is no limit to people's interest in how it works. So, in the beginning I want to say with examples that there is no limit to the power of the human mind. In one mind man creates his own past, present, future.
You may suddenly think, today is a different day. Something is different. Thinking in your mind, any of your dear relatives will come home today, what is the result, how far is the job - it does not embarrass you. That actually makes you feel great. Although there is no reason for him to come. Still, if you look back at your relative sitting there, looking at you and smiling!
You are thinking of someone, his position strongly dominates your thoughts. You want to talk to him. Just then the man called you.
***Why do these things happen?***
The first research on telepathy was started around 182. Sir William Barrett, professor of physics at the Royal College of Sciences in Dublin, England, convened a conference inspired by the initial success of his research on telepathy. It was at that conference that the Society for Psychical Research was formed to better study telepathy and "Extra Sensory Perception (ESP)".
Frederick Myers, founder of the Society for Psychological Research, first used the term "telepathy". The word telepathy comes from the Greek words tele and pathia. The word tele means, distant, the word pathia means feeling. There is no real means of communication in the middle, yet someone far away is being influenced by your feelings or thoughts, the thoughts that are being transferred to them can be called telepathy.
Although the scientific basis of this matter is not so strong. Nevertheless, there is no end to the research on this branch of parapsychology. Scientists have tried to explain telepathy through two different theories. First let's talk about radio web theory. This theory says that when a person thinks, a kind of radio web is generated from his brain. If someone else accepts this web, they can get an idea of what the person is thinking. There are problems with this theory. If this theory were true then the human brain wave or web could be measured from a great distance. But, so far no device has been able to detect human brain waves from a distance of more than a few centimeters. So many people could not accept this theory.
Another theory of telepathy is the Timeless / Spaceless Psychic Field theory. This theory says that every human being's thoughts are stored in a "Psychic Field". Thoughts are known from this psychic field, those who can do telepathy can try to capture thoughts from this psychic field in this way. But the funny thing is, no scientific basis for this kind of Psychic Field is clear yet.
Of course, there is also an explanation of telepathy in quantum theory. Quantum theory says that even if two fundamental particles that are related to each other are placed far apart, their behavior will still depend on each other. One particle will understand the behavior of another particle and the effect of such behavior will fall on it as well. The idea is that the two particles are connected through a "non-local" domain, which is beyond space and time. According to this theory, we are all connected to each other through one or another "non-local" domain. This means that even if two people were taken to two different ends of the planet, they would still be able to understand each other's state of mind!
Guthrie Experiment - The young physicist Sir Oliver Lodge tried to open new horizons in telepathy research. Oliver Lodge tried to telepathy by transferring diagrams. His experiment was quite successful. The work by Oliver Lodge is referred to as the "Gathri Experiment" in a report by the Society for Psychiatric Research. Mr. Liverpool school teacher. Malcolm Guthrie was the thinker in this study. Mr. Guthrie's job was to focus on the drawings of Sir Oliver Lodge. Mr. The idea of this diagram was transferred from Gathri's brain through telepathy to the brain of a woman on the other side. The woman did not know what the diagram was going to be. But, he drew the replica of the diagram that he got through Gathri's telepathy!
After this study, many more people were encouraged to study telepathy.
The most exciting news of telepathy research was published during the lunar mission of Apollo 14 in 1971. At the time, rumors were circulating that Apollo 14 astronaut Capt. Edgar Mitchell had conducted a mysterious study of ESP from the moon. It is claimed that he communicated with the earth via telepathy a total of six times from the lunar spacecraft. But mysteriously the details of this study were not known. Even, this study is officially denied!
However, we may continue to call the supernatural events a coincidence or a mistake of the mind! We think of the world of unexplained events as a world of confusion. Science may come up with a unanimous explanation, then we will understand everything with scientific explanation. But, is it right to dismiss this power of the mind as mere delusion?
The Doppler Effect
You're sitting in a jam. Airport Road Jam. An ambulance is rushing along the road opposite to you, honking its siren! You are praying in your heart that whoever is inside the ambulance, he should reach the hospital as soon as possible. 🙁 But the closer the ambulance gets to you, the more annoying the siren sounds! When the ambulance was passing by you, it seemed that it was over! This discomfort started to subside after you passed, then it didn't happen again later. Why is that? What is it for? Today's discussion of the Doppler effect in physics is to answer these questions.
The Doppler effect is the change in the frequency of a wave due to the relative motion between the source and the observer. The definition seems a little difficult, doesn't it? Let's do a detailed research on it, then you will see that it is straight like water. To better understand this, let us recall the incident I mentioned earlier when the sound of the siren was getting louder as the ambulance was advancing on the siren.
The fact that the ambulance was coming to you with a siren sounded, but not that the louder or louder the sound came out of the speaker as it approached you! But they remain unchanged! But still you can hear loud and sharp sounds only because of the increase in its apparent frequency. 🙂 And due to the relative velocity of the listener (you) and the source (siren mounted above the ambulance) the apparent change in the frequency of the sound wave is felt, this is the Doppler effect! This Doppler effect is seen only in the case of words but not! We look at how matter works in the case of just sound waves.This applies to any wave.
***A few important things:***
1) The Doppler effect will be felt in the direction where the apparent velocity of the listener or source exists. An ambulance is heading east with a siren sounding, you stand on the ambulance and jump. The direction of your jump must be along the north here. Since the angle difference between the source and the listener's velocity is 90 degrees, the Doppler effect will not work here.
2) Doppler effect will not work if the speed of sound from the source is less than the speed of the listener.
Selfish and Ignore
Selfish and Ignore "These two words are very important for life. The role of these two words to be good is infinite, you will be good from the time you learn to be selfish and ignore.
. You are not good, you are responsible for it yourself, why are you not good if you go to find the reason, then you will see that someone is neglecting you, avoiding you, putting huge interests on your head but you can't ignore them, you can't have your own interests. To impose on them.
Notice those who ignore you or have a vested interest in you, but they are happy to swear only you are unhappy because you can't ignore, you don't even know how to be selfish.
. You don't have to put up with your teeth all the time and understand everything. Sometimes you have to say 'no'. If you want to survive, you have to learn to say 'no', you have to avoid it, you have to wash your face if you get hurt too much. Then you will be fine.
"Neglect is not just a word, it's another name for suffering." Whoever neglects you, you also neglect him, whoever avoids you, you also avoid him, if you want to go ahead again and again in the hope of getting closer, in return you will only suffer.
. Don't go to explain to him who doesn't understand you, don't be a laughing stock to him who can't stand you. Personality is big value, just why are you wasting your sacred passion for the wrong people? Emotions are very expensive, if you give all the emotions to the wrong person, what will the real person give him? .
Block the one you can't see from everything, avoid the one who can't see you, you'll be fine. Honestly, it will be good. Say goodbye to the wrong people, turn around and look around, you will see hundreds of people waiting for you.
. The man who has become selfish, has learned to ignore the importance of being selfish and learning to ignore in order to be good in life. You too will learn, time will teach you, but learn from yourself rather than teach time because - "Time not only teaches, it also goes through hardships !!
Give me Books
Not the crest, the book. Not Cups, Not trophies, only books.
If you take me to an event, please don't give me a crest. There is no place to keep the crest in my home and office. Buy any book with that money and give it to me as a gift.
Fear not, if good books become duplicates, I still keep them at home. If not, I give a gift to a loved one. Give books as prizes in any competition in all schools and colleges. Even if the book is given as a prize in a sports competition, it will be the best gift.
Books can change the life of an award-winner forever from light to good. Let's choose the book as the prize. Let's establish the book.Establish our knowledge........
SunRise
We begins our day with Sunrise. New day means new expectations, new feelings, new fashions.The sunlight is not also light the world but also light our everyday life..
We believe to new day is always good. If our today is worst ,than we wait for tomorrow just hoping to something good will happen. The dark night will graveyard our tensions and the next sunrise will light our life too colorful.
When it is time to rise sun ,the light is too silky-smooth that we feel so energetic after the light comes on in our skin.
It's very sweet Sunrise today.....Good Morning to all...
