I learnt how does wifi works. Wifi ( also known as wireless fidelity) uses radio waves to transmit information between ur device and a router via frequencies. 2 radio-wave frequencies can be used, depending on the amount of being sent 2.4 gigahertz or 5 gigahertz. So like a hertz is a measurement of frequencies. for example, when u sit on a beach and u see the waves of the beach one by one crashing onto the shore. if u measured the time between each wave crash, like wave_____wave_____wave, u will be measuring the frequency of the waves, like how frequent the waves crash onto the shore. 1 hertz is a frequency of 1 wave per second, but one gigahertz, is one BILLION waves per second. The higher the frequency (or the speeeed), the greater the amount of data transmitted in one sec.
The 2 wifi frequencies are split into multiple channels so that it can prevent high traffic and interferance. When it comes to sharing the data across these channels, thats where the interesting part comes in.
1. This step is initiated by the user (you). When u access the internet on ur device, it converts the information u requested into binary code ( thats how the computers read it faster since its jus numbers of 0 and 1 ), the computer lanaguage. When you click on this article, your request is translated into a bunch of 1 and 0. If you’re using wifi, these 1 and 0 are translated into wave frequencies by the wifi chip embedded in your device. The frequencies travel across the radio channels mentioned earlier and are received by the wifi router that ur device is connected to. The router then converts the frequencies back into binary code and translates the code into the Internet traffic that you requested, and the router receives that data through a hardwired Internet cable. The process repeats itself until u have loaded this article—or anything that requires the Internet. All of this happens at an unbelievably fast rate; most routers operate at 54 Mbps (megabits per second), meaning that when such routers translate and transmit binary data, 54 million 1 and 0 are taken in or sent out in a single second. And thats how the wifi works.

today i learned more about spacetime. space time is the space that fills the observable universe. the faster your speed and greater your mass, the more it will bend. the time in space however, moves at the same pace and in the same direction. for example, i time travel to an hour ago, time will still travel at the same time and speed, foward. so, if there was absoutely nothing in the universe, it would be timeless, since there is nothin to ben spacetime. i also don't trust the internet so this might be false.

I learnt what is a white hole.A white hole is like a black hole but instead of sucking up matter,it releases matter and light but nothing can come back in.In 2006,scientists witness a birth of a white hole.They do not exist for a long time unlike black holes.People do not really know how white holes are form but theories suggests that it is a death of a black hole or it could be a wormhole meaning that whatever is sucked up by a black hole,may come out through by a white hole.Black holes are usually made by a stars bigger than the sun and dies with a supernova but white holes do not form or dies like that

i learnt how to play chess this are the steps
The queen is the most powerful piece. She can move in any one straight direction - forward, backward, sideways, or diagonally - as far as possible as long as she does not move through any of her own pieces.

The rook may move as far as it wants, but only forward, backward, and to the sides

The bishop may move as far as it wants, but only diagonally. Each bishop starts on one color (light or dark) and must always stay on that color.

Knights move in a very different way from the other pieces – going two squares in one direction, and then one more move at a 90-degree angle, just like the shape of an “L”.

Pawns are unusual because they move and capture in different ways: they move forward but capture diagonally. Pawns can only move forward one square at a time, except for their very first move where they can move forward two squares.

Pawns have another special ability and that is that if a pawn reaches the other side of the board it can become any other chess piece (called promotion) excluding a king (or pawn, for that matter).

i learn about time travel.It is said that time travel is possible except its not like the ones we think in movies.You see,the faster we travel,the slower we go through time and the opposite can said as well.For example, two clocks set to the exact same time. One clock stayed on Earth, while the other flew in an airplane (going in the same direction Earth rotates).

After the airplane flew around the world, scientists compared the two clocks. The clock on the fast-moving airplane was slightly behind the clock on the ground. So, the clock on the airplane was traveling slightly slower in time than 1 second per second.

I also learnt what general relativity is.It is how space is distorted because of massive objects. Imagine setting a large object in the center of a trampoline. The object would press down into the fabric, causing it to dimple. If you then attempt to roll a marble around the edge of the trampoline, the marble would spiral inward toward the body, pulled in much the same way that the gravity of a planet pulls at rocks in space.

i learned how to fingerpick a guitar and more about the guitar. The bridge is the part at the front of the guitar and it holds all the 6 strings. connecting the strings to the bridge is the string pegs. on the body of the guitar, the sound hole is what amplifies the sounds made by the strings and connected to the guitar body is the guitar neck. on the guitar neck, there are many studs called frets and they show where to put your finger when you want to make a certain sound. on the top of the guitar head, which is what has the tuning keys. the tuning keys are what you turn when you want to tune the guitar when it is out of tune. Fingerpicking is like plucking the strings but with chords. so it sounds like im playing guitar chords but more smooth and nicer to listen to. I am so happy guitar was my cca in primary school.

i learnt about tips and tricks of how to play chess better firstly OPEN WITH A PAWN which means Move the pawn in front of either the king or queen two squares forward. (Only on its opening move can a pawn move two squares.) This opens pathways for your bishops and queen to enter the game. They move on an angle and can’t get out onto the field of battle if pawns are in the way. secondly GET THE KNIGHTS AND BISHOPS OUT which is Before you move your queen, rooks or king, move your knights and bishops toward the center of the board. You want to get these pieces out from behind the pawns so they can attack thirdly WATCH YOUR BACK! And front!  which is When it’s your turn, always think to yourself, “What did my opponent’s last move do? What is he up to?” Is he laying traps to capture your pieces? Then decide on your own plan. Always look at all your possibilities. Look at moves that would capture your opponent’s men or threaten his king first. But always double-check your moves before you play them. Ask yourself, “Does my move leave something unprotected?” lastly “CASTLE” EARLY
is a important move Castling is a move that allows you to move your king to safety and bring your rook into play. Once all the squares between your rook and the king are unoccupied you can move the king two squares toward the rook while the rook moves to the square on the the king’s other side. If your opponent neglects to castle, you might be able to launch an attack on his king. This is the only move in which more than one piece may be moved in a turn.

I learnt how to smash a shuttle in badminton.
To smash in badminton, start by standing with your feet shoulder-width apart and your knees slightly bent. When the shuttle comes toward you, hold your racket upright and as far back as possible. Then, inhale deeply and and swing your racket to connect with the shuttle at the highest point possible.
I learnt to bend my arm to the back because it gives you a lot more power and momentum which allowed me to actually smash the shuttle with more force and earn the point in that singles match of badminton.
Now my smash is a lot more powerful and useful in my badminton matches when I need to end the rally and get the point.

I learnt about the general theory of relativity.
It was created by Albert Einstein in 1905 as his first version of special relativity and only finished the whole theory after decades of experiments.
So what is the general theory of relativity?
first, the theory is based on 2 concepts.
1.  As long as an object is moving in a straight line at constant speed( not slowing down or speeding up), the laws of physics are the same for everyone. For example, its like you are in a moving train, and you see a non-moving train beside you, you will see that the non-moving train is going further away from you( since you are moving away from it). But what if your train is not moving and the train you thought was not moving is actually moving backwards away from you. Then there will be no or very little difference between the 1st scenario and 2nd scenario. Einstein recognized that if the motion is perfectly the same, its literally impossible to tell--- thus he identified this as a centre principle of physics.
2. Light travels very fast at 186,000 miles per second. No matter how fast an observer is moving or how a fast a light-emitting object is moving, a measurement of the speed of light always yields the same results.
If you’re zooming along in a rocket and pass a friend in an identical but slower-moving rocket, for example, you’ll see that your friend’s watch is ticking along more slowly than yours. This is called time dilation.

What’s more, your friend’s rocket will appear shorter than your own. If your rocket speeds up, your mass and that of the rocket will increase. The faster you go, the heavier things become and the more your rocket will resist your efforts to make it go faster. Einstein showed that nothing that has a mass can ever reach the speed of light.
Basically, The general theory of relativity is a theory of gravity. Instead of gravity being an invisible force and pulling stuff, gravity is a curving of space and time. The more massive an object, the more it wraps its space around it.

imagine you are in a rocket, in deep space, floating around. Inside the rocket everything is floating ( no gravity in space), but when you on the rocket engines and the rocket starts to move, all of the objects including you in the rocket start to fall to the floor( or move towards the rocket thrusters). This means that when we are moving, we stop floating around. So there is no gravity. If you are standing up right now and not floating, does this means that you are moving?
The only way to know that if you are moving is from an inertial observer seeing you( an observer that is away from all gravity fields, just like in deep space or if u feel weightless), so if you jump down from a building, ur an inertial observer, since you feel no weight on you, and ur floating. The people in the building as you see, will be going upwards and accelerating. And the floor is also accelerating to you so you will crash and die.
About gravity being a curving or wrapping of spacetime, heres an example:
the sun is massive enough to warp space across our solar system — a bit like the way a heavy ball resting on a rubber sheet warps the sheet. As a result, Earth and the other planets move in curved paths (orbits) around it.

This warping also affects measurements of time. We tend to think of time as ticking away at a steady rate. But just as gravity can stretch or warp space, it can also dilate time. If your friend climbs to the top of a mountain, you’ll see his clock ticking faster compared to yours; another friend, at the bottom of a valley, will have a slower-ticking clock, because of the difference in the strength of gravity at each place. Like if you are in spaceship and you are supposed to go straight and your spaceship sensors says that you are going straight, you are actually moving towards a planet. You will also feel no difference in the spaceship about moving not straight, but from an observer you are slowly moving towards the planet. This is because the planet has a wrap of spacetime around it and you are following the wrap, so you cannot go straight because the floor prevents you from doing so. And not because of gravity pulling you towards it.
This is my research findings of the general theory of relativity.

I learnt the main line vienna gambit
The gambit is best met by 3...d5, striking back in the center. After 4.fxe5 Nxe4, 5.Qf3 is well met by 5...Nc6, with the point 6.Nxe4 Nd4. 5.d3 is also possible, but the normal continuation is 5.Nf3. White obtains open lines and attacking chances, but Black can usually hold the balance with correct play.

However, lines other than 3...d5 give White at least an edge, making this a good choice for aggressive play at lower levels, where opponents are unlikely to know that 3...d5 is best.

The gambit should not be accepted, since 3...exf4 4.e5 Qe7 5.Qe2 forces Black's knight to retreat with 5...Ng8, and after 6.Nf3, Black must be careful not to lose on the spot, for example after 6...d6? 7.Nd5!, when the dual ideas of Nxc7 and exd6 will win the game quickly. Retreating immediately with 4...Ng8 is better, but after 5.Nf3 with the idea of d4 followed by Bxf4, White has a nice game.

Other lines for Black include 3...d6 4.Nf3 Nc6 5.Bb5 Bd7 6.d3, when the threat of Bxc6 followed by taking on e5 induces 6...exf4 7.Bxf4, leaving White with a pleasant position; and also 3...Nc6? 4.fxe5! Nxe5 5.d4, when both 5...Nc6 and 5...Ng6 are met by 6.e5 with a winning advantage to White. Material is not as important as the attack in this position, so White should not be afraid to sacrifice.

This machine that is being built is the main part of an experimental fusion nuclear power plant. It can produce nearly four million times more energy than a chemical reaction such as the burning of coal, oil or gas and four times as much as nuclear fission reactions (at equal mass). The process used to make electricity is the same as how the sun works. The heat created (150million deg Celcius) is used to boil water, to make steam, to turn the generator. It is still experimental, the first one is still being built and expected to be completed by 2050. The good thing is that Fusion doesn't emit harmful toxins like carbon dioxide or other greenhouse gases into the atmosphere. Its major by-product is helium: an inert, non-toxic gas. What's more, it doesn't release any radioactive waste! And don't worry, they are not building a bomb on earth, A Fukushima-type nuclear accident is not possible in a tokamak fusion device. It is difficult enough to reach and maintain the precise conditions necessary for fusion—if any disturbance occurs, the plasma cools within seconds and the reaction stops. The quantity of fuel present in the vessel at any one time is enough for a few seconds only so there is no risk of a chain reaction. While building power plants like this will be very expensive, it will be cheaper in the future when the parts are manufactured by constantly.

I learned  the basis of playing table tennis. The way you hold the bat is very special. Instead of holding it like hold you hold a badminton racket for example, you hold it in between your thumb and index finger. Table tennis is just like normal tennis just that you are not in the court but outside of the court. How to play table tennis is almost the same as tennis. Every two points won the other person would serve. I would prefer table tennis over tennis for a few reasons. First, it requires lesser strength to hit the ball over the net as the ball is much lighter than the tennis ball. Second, The bat is the same type most of the time, however, the tennis rackets and more customisable.

i learnt about travelling around the universe. as of now, we do not have any spacecraft technology that can accelerate a vehicle at 1G for long periods of time. It turns out, if you accelerate at 1G for several years, you can reach almost any destination in the universe.
Lets say you have a vehicle that can accelerate at 1G in space. If you accelerate at 1G, your speed increases at 9.81m/sec. After one year, you would be travelling at about 309 million m/s, which is 103 percent the speed of light. However, relativity tells us you cant really travel faster than the speed of light, but you can get closer and closer to it, but never reach it. So, what happens to you when you are accelerating at 1G? Strangely, nothing happens from your point of view as your vehicle approaches the speed of light. You just continue accelerating. But, if you look at the universe around you, you'll notice things getting a little strange.
As you go faster, the passage of time on board your vehicle slows down. It seems to take you less time than it should to reach successive landmarks along your trip-as if the universe has contracted in the direction you are travelling in.
After a year has passed for you on board your vehicle, you would be travelling at 3/4 the speed of light. In the outside world, a year and two months would have passed. The disparity between time on your scooter and time on the outside world keeps growing. after 1 and a half years have passed on board, you'll have travelled almost 1 and a half light years. after 2 years on board, you'll have gone more than 2 light years, as if you travelled faster than light!
after a few years have passed on board, the effects of relativity will start to add up. when 3 years have passed for you, a little over 10 years would have passed outside your vehicle. Remember, you are still accelerating at 1G. after 4 years for you, you would have gone 30 light years, and you'll be travelling at 99.95 percent the speed of light. after 5 years, you'll be 80 light years from where you started and after 10 years, you;ll have travelled 15,000 light years, bringing you halfway to the center of the Milky-Way. However, if you keep accelerating, you will never reach the edge of the universe because dark energy expands the universe.you wont get old, but the universe around you will. if you have travelled long enough, the universe would start to die out. after 40 years on board, the universe would become cold and empty, and even the longest living stars would die out. there would only be intermittent flashes when the drifting husks of dead stars collide.
no matter how far you go, you will never reach the edge of the universe. but you can reach the end.

what i learnt :
cesarean  section
what is it ?
cesarean section is a surgical procedure used to deliver a baby through incisions in the abdomen and uterus.
why its done ?
its done if you develop pregnancy complications or you've had a previous C-section and aren't considering a vaginal birth after cesarean. But most of the time ,C-section doesn't become obvious until labor is underway.
risks :
there are many risks for both the baby and the mother . the are more risks for the mother than the baby .

I learnt about quantum immortality
Quantum immortality is:

The quantum suicide thought experiment involves a similar apparatus to Schrodinger's cat – a box which kills the occupant in a given time frame with probability one-half due to quantum uncertainty. The only difference is to have the experimenter recording observations be the one inside the box. The significance of this is that someone whose life or death depends on a qubit could possibly distinguish between interpretation of quantum mechanics. By definition, fixed observers cannot.

At the start of the first iteration, under both interpretations, the probability of surviving the experiment is 50%, as given by the squared norm of the wave function. At the start of the second iteration, assuming a single-world interpretation of quantum mechanics (like the widely-held Copenhagen interpretation) is true, the wave function has already collapsed; thus, if the experimenter is already dead, there is a 0% chance of survival for any further iterations. However, if the many-worlds is true, a superposition of the live experimenter necacerrily  exists (as also does the one who dies). Now, barring the possibility of life after death, after every iteration only one of the two experimenter superpositions – the live one – is capable of having any sort of conscious experience. Putting aside the philosophical problems associated with indiviual identity and its persistance, under the many-worlds interpretation, the experimenter, or at least a version of them, continues to exist through all of their superpositions where the outcome of the experiment is that they live. In other words, a version of the experimenter survives all iterations of the experiment. Since the superpositions where a version of the experimenter lives occur by quantum necessity (under the many-worlds interpretation), it follows that their survival, after any realizable number of iterations, is physically necessary; hence, the notion of quantum immortality.

A version of the experimenter surviving stands in stark contrast to the implications of the Copenhagen interpretation, according to which, although the survival outcome is possible in every iteration, its probability tends towards zero as the number of iterations increases. According to the many-worlds interpretation, the above scenario has the opposite property: the probability of a version of the experimenter living is necessarily one for any number of iterations.

i learnt about the theories of the bermuda triangle.
The Bermuda Triangle is a large area of ocean between Florida, Puerto Rico, and Bermuda. Over the last few centuries, it’s thought that dozens of ships and planes have disappeared under mysterious circumstances in the area, earning it the nickname “The Devil’s Triangle.” The Bermuda Triangle’s bad reputation started with Christopher Columbus. According to his log, on October 8, 1492, Columbus looked down at his compass and noticed that it was giving weird readings. He didn’t alert his crew at first, because having a compass that didn’t point to magnetic north may have sent the already on edge crew into a panic. This was probably a good decision considering three days later when Columbus simply spotted a strange light, the crew threatened to return to Spain.
This and other reported compass issues in the region gave rise to the myth that compasses will all be off in the Triangle, which isn’t correct, or at least is an exaggeration of what is actually happening as you’ll see.  Despite this, in 1970 the U.S. Coast Guard, attempting to explain the reasons for disappearances in the Triangle, stated:

First, the “Devil’s Triangle” is one of the two places on earth that a magnetic compass does point towards true north. Normally it points toward magnetic north. The difference between the two is known as compass variation. The amount of variation changes by as much as 20 degrees as one circumnavigates the earth. If this compass variation or error is not compensated for, a navigator could find himself far off course and in deep trouble.

Of course, despite this now being repeated as an explanation for disappearances in the Triangle on numerous documentaries and articles since then, it turns out magnetic variation is something ship captains (and other explorers) have known about and had to deal with pretty much as long as there have been ships and compasses. Dealing with magnetic declination is really just “Navigation by Compass” 101 and nothing to be concerned about, nor anything that would seriously throw off any experienced navigator.

Coast Guard revisited the issue after a TV producer in London inquired about it for a program he was working on.  In this case, they correctly changed their tune about the magnetic field bit stating,

Many explanations have cited unusual magnetic properties within the boundaries of the Triangle. Although the world’s magnetic fields are in constant flux, the “Bermuda Triangle” has remained relatively undisturbed.  It is true that some exceptional magnetic values have been reported within the Triangle, but none to make the Triangle more unusual than any other place on Earth.

The Bermuda Triangle is a large area of ocean between Florida, Puerto Rico, and Bermuda. Over the last few centuries, it's thought that dozens of ships and planes have disappeared under mysterious circumstances in the area, earning it the nickname "The Devil's Triangle." People have even gone so far as to speculate that it's an area of extra-terrestrial activity or that there is some bizarre natural scientific cause for the region to be hazardous; but most likely, it's simply an area in which people have experienced a lot of bad luck-the idea of it being a "vortex of doom" is no more real than Bigfoot or the Loch Ness Monster (see The Origin of the Bigfoot Legend and The Origin of the Loch Ness Monster).

The Bermuda Triangle's bad reputation started with Christopher Columbus. According to his log, on October 8, 1492, Columbus looked down at his compass and noticed that it was giving weird readings. He didn't alert his crew at first, because having a compass that didn't point to magnetic north may have sent the already on edge crew into a panic.

Despite this, in 1970 the U.S. Coast Guard, attempting to explain the reasons for disappearances in the Triangle, stated:

First, the "Devil's Triangle" is one of the two places on earth that a magnetic compass does point towards true north. Normally it points toward magnetic north. The difference between the two is known as compass variation. The amount of variation changes by as much as 20 degrees as one circumnavigates the earth. If this compass variation or error is not compensated for, a navigator could find himself far off course and in deep trouble.

In 2005, the Coast Guard revisited the issue after a TV producer in London inquired about it for a program he was working on. In this case, they correctly changed their tune about the magnetic field bit stating,

Many explanations have cited unusual magnetic properties within the boundaries of the Triangle. Although the world's magnetic fields are in constant flux, the "Bermuda Triangle" has remained relatively undisturbed. It is true that some exceptional magnetic values have been reported within the Triangle, but none to make the Triangle more unusual than any other place on Earth.

The modern Bermuda Triangle legend didn't get started until 1950 when an article written by Edward Van Winkle Jones was published by the Associated Press. Jones reported several incidences of disappearing ships and planes in the Bermuda Triangle, including five US Navy torpedo bombers that vanished on December 5, 1945, and the commercial airliners "Star Tiger" and "Star Ariel" which disappeared on January 30, 1948 and January 17, 1949 respectively. All told, about 135 individuals were unaccounted for, and they all went missing around the Bermuda Triangle. As Jones said, "they were swallowed without a trace."

It was a 1955 book, The Case for the UFO, by M. K. Jessup that started pointing fingers at alien life forms. After all, no bodies or wreckage had yet been discovered. By 1964, Vincent H. Gaddis-who coined the term "Bermuda Triangle"-wrote an article saying over 1000 lives had been claimed by the area. He also agreed that it was a "pattern of strange events." The Bermuda Triangle obsession hit its peak in the early 1970s with the publication of several paperback books about the topic, including the bestseller by Charles Berlitz, The Bermuda Triangle.

However, critic Larry Kusche, who published The Bermuda Triangle Mystery: Solved in 1975, argued that other authors had exaggerated their numbers and hadn't done any proper research. They presented some disappearance cases as "mysteries" when they weren't mysteries at all, and some reported cases hadn't even happened within the Bermuda Triangle.

After extensively researching the issue, Kusche concluded that the number of disappearances that occurred within the Bermuda Triangle wasn't actually greater than in any other similarly trafficked area of the ocean, and that other writers presented misinformation-such as not reporting storms that occurred on the same day as disappearances, and sometimes even making it seem as though the conditions had been calm for the purposes of creating a sensational story. In short: previous Bermuda Triangle authors didn't do their research and either knowingly or unintentionally "made it up."

The book did such a thorough job of debunking the myth that it effectively ended most of the Bermuda Triangle hype. When authors like Berlitz and others were unable to refute Kusche's findings, even the most steadfast of believers had difficulty remaining confident in the sensationalized Bermuda Triangle narrative. Nevertheless, many magazine articles, TV shows, and movies have continued to feature the Bermuda Triangle.

Because the number of disappearances in the Bermuda Triangle is no greater than any other similarly trafficked area of the world's oceans, they don't really need an explanation. But if you're still convinced that the Triangle is a ship graveyard, relative to other regions that get around the same number of travelers, here are some natural explanations from the Coast Guard to combat some of the "alien" and other fantastical theories.

The majority of disappearances can be attributed to the area's unique features. The Gulf Stream, a warm ocean current flowing from the Gulf of Mexico around the Florida Straits northeastward toward Europe, is extremely swift and turbulent. It can quickly erase any evidence of a disaster.

The unpredictable Caribbean-Atlantic storms that give birth to waves of great size as well as waterspouts often spell disaster for pilots and mariners. (Not to mention that the area is in "hurricane alley.") The topography of the ocean floor varies from extensive shoals to some of the deepest marine trenches in the world. With the interaction of strong currents over reefs, the topography is in a constant state of flux and breeds development of new navigational hazards.

Not to be underestimated is the human factor. A large number of pleasure boats travel the water between Florida's Gold Coast (the most densely populated area in the world) and the Bahamas. All to often, crossings are attempted with too small a boat, insufficient knowledge of the area's hazards and lack of good seamanship.

Bonus Facts:

Whatever the rumours might have you believe, insurance companies don't actually charge higher premiums for shipping in the Bermuda Triangle.

Another mysterious "triangle" is the Michigan Triangle-an area stretching between Michigan and Wisconsin over the centre of Lake Michigan where disappearances have occurred. One disappearance was Captain George R. Donner who supposedly simply vanished from his cabin on the O.S. McFarland as it carted coal to Wisconsin. On April 28, 1937, his second mate went to tell him they were approaching port, but no one could find him anywhere aboard the ship. In another instance, a plane was flying above the triangle and *apparently* just disappeared. Small amounts of debris were found floating in the water, but the rest of the wreckage and bodies of passengers weren't found. If you guessed that little credence is given to this triangle being an area of unusual activity for similar reasons as the Bermuda Triangle misrepresentations, you'd be correct.

I learnt about something called the dramaturgy theory.
Sociologist Erving Goffman developed the concept of Dramaturgy, the idea that life is like a never-ending play in which people are actors. Goffman believed that when we are born, we are thrust onto a stage called everyday life, and that our socialization consists of learning how to play our assigned roles from other people. We enact our roles in the company of others, who are in turn enacting their roles in interaction with us. He believed that whatever we do, we are playing out some role on the stage of life.

Goffman distinguished between front stages and back stages. During our everyday life, we spend most of our lives on the front stage, where we get to deliver our lines and perform. A wedding is a front stage. A classroom lectern is a front stage. A dinner table can be a front stage. Almost any place where we act in front of others is a front stage. Sometimes we are allowed to retreat to the back stages of life. In these private areas, we don’t have to act. We can be our real selves. We can also practice and prepare for our return to the front stage

Today I learnt about the French Revolution. The French revolution, also known as the Revolution of 1789, was a period of time when the people in France overthrew the monarchy and took control of the government. The French Revolution lasted for 10 years, 6 months and 4 days and of which, killed over 1,700 citizens. It happened from 5 May 1789- 9 November 1799.On July 14, 1789, thousands of Parisians stormed the Bastille, a prison in Paris, to protest King Louis XVI's abuse of power. It was a defining moment of the revolution that toppled the monarchy.  What sparked the French Revolution was that the commoners were unhappy about 10 major reasons: The social inequality in France, Tax burdens, the rise of Bourgeoisie, Ideas put forward by the Enlightenment Philosophers, Financial crisis due to costly wars, drastic weather and poor harvests in the preceding years, the rise in the cost of bread, ineffective leadership of Louis XV and Louis XVI, the parliament’s successful opposition to reforms and the extravagant lifestyle of the French Monarchy. Finally, The French Revolution came to an end 1799 when a general named Napoleon overthrew the revolutionary government and established the French Consulate (with Napoleon as leader). So, how did this impact France? The French Revolution completely changed the social and political structure of France.  It put an end to the French monarchy, feudalism, and took political power from the Catholic church.                                    It brought new ideas to Europe including liberty and freedom for the commoner as well as the abolishment of slavery and the rights of women. Although the revolution ended with the rise of Napoleon, the ideas and reforms did not die. These new ideas continued to influence Europe and helped to shape many of Europe's modern-day governments.

Tetris is a popular game made in 1984 and is one of the most well-known games in the world. While it seems like an extremely simple game, Tetris is surprisingly hard to master. I thought it was really intriguing, so I decided to try and learn how to improve in tetris.

Introduction
Tetris is a game in which pieces made of four squares are stacked on top of each other. In order to clear a line of pieces, there needs to be a line fully filled. The pieces all have four squares, which means that there are 7 possible shapes that can appear, which can also be rotated. There are many ways people play the game such as getting the highest score, clearing the most lines, clearing the most lines in a set amount of time, clearing a set amount of lines as fast as possible and getting the highest score in a set amount of time.

Strategies to improve
With so many ways to play the game, there are many strategies that has come up over the years, some better than others. There are a few areas in Tetris I intended to improve myself in, which where:
1: Strategies
2: Planning
3: Accuracy

1: Strategies
One of the strategies I learnt and eventually started using the most was "The well strategy", where there was a "well" at one side of the area where the player would place a long bar(a piece that was a straight line) in order to clear the most amount of lines possible. This strategy allowed the player to control the stack of pieces from topping out(where the pieces hit the top of the screen and causes the player to lose the game).

However, not everything is without disadvantages. If the player were to accidentally cover up the "well", they would not be able to clear the lines at the bottom and thus stand a higher chance to top out, unless they knew how to get out of tough situations.

2: Planning
Planning is arguably one of the most important aspects of Tetris. Planningallows a player to plan where they would want to place their piece. This allows for better efficiency for the placement of pieces. Some ways to improve planning is to try and take a look at the next piece and see where it fits. Human brains aren't very good at going through every single option and picking the best one out of all of them, so instead of going through every option, its better to go through every option that looks feasible. It's a good way for people to get better with planning ahead and it worked really well for me.

3: Accuracy
As simple as it may sound, accuracy is really hard to master because not everyone has amazing coordination and most people won't be able to do something over and over again all the time because everyone is prone to mistakes. However, there are still ways to improve your accuracy. One such way is to practice placing the pieces in a certain order that you want them to be in. It doesn't have to be in any exact order because its just for practicing your accuracy. It might take a while but you'll eventually be able to see the fruits of your labour.

Summary

Although Tetris is a hard game to master with many different mechanics, with enough practice and experience, you could easily improve in it with enough practice. Tetris really fascinated me with its many mechanics and different strategies, but I didn't only just learn how to improve in Tetris, I also realised that humans can do many things if they put in the effort to do so.

also i didnt copy and paste this so uh my hands AAAA

where was this kind of language during my english compos what a scam i want a refund

Drape the tie around your neck. With your collar up and your shirt fully buttoned, place the tie around your shoulders. Hang the wider end of the tie on your right side, with the narrow end about 12 inches (30 cm) higher on the left. Cross the wide end over the narrow end. Bring the wide end to the left side of your body, over the narrow end. Hold the two pieces of cloth together with your left hand, near your neck.Loop the wide end under the narrow end. Let go with your right hand. Tuck it underneath the narrow end, grab the wide end, and pull it back through to your right side. Loop the wide end back over again.. Cross it over the narrow end one more time, at the same point where your left hand is holding the knot together.

today i learnt about vtubers which stand for virtual-youtubers.

This technology is what I feel like is an early representation of what the future is, intertwining with Mark Zuckumbergs metaverse

These "Vtubers" are real people who can show themselves as a virtual avatar on online platforms such as youtube or twitch, this allows themselves to show facial expressions without using their real face.

This groundbreaking technology was invented back in 2016 and has become so mainstream that in todays modern era Singapore has also introduced this technology with their own vtuber as 2021's national day mascot, August the Merlion, making his debut https://youtu.be/Uzbr8HMMCFg.

The popularity of Vtubers first skyrocketed during the COVID-19 pandemic when social interaction was at an all time low and people needed to feel connected with others in some way, this resorted in people joining the Vtuber community.

We now live in a day and age where people can make millions behind an animate face as shown in this video: https://youtu.be/I9VHuPgZ6NE

In conclusion today I have learned about Vtubers ,their impact on people during the COVID-19 pandemic, the economy and being an influencer in 2022. With this knowledge I predict Vtubers will only rise further and soon be implemented into the everyday lives of EVERYBODY on this planet.

No, this was not copy and pasted.

I learnt how spending too much time on social media can affect us
Humans are social creatures. We need the companionship of others to thrive in life, and the strength of our connections has a huge impact on our mental health and happiness. Being socially connected to others can ease stress, anxiety, and depression, boost self-worth, provide comfort and joy, prevent loneliness, and even add years to your life. On the flip side, lacking strong social connections can pose a serious risk to your mental and emotional health.

In today’s world, many of us rely on social media platforms such as Facebook, Twitter, Snapchat, YouTube, and Instagram to find and connect with each other. While each has its benefits, it’s important to remember that social media can never be a replacement for real-world human connection. It requires in-person contact with others to trigger the hormones that alleviate stress and make you feel happier, healthier, and more positive. Ironically for a technology that’s designed to bring people closer together, spending too much time engaging with social media can actually make us feel more lonely and isolated and exacerbate mental health problems such as anxiety and depression .

I almost finished learning all last layer algorithms for the Rubik's cube.
more specifically:
V-perm* ( better alternative)
R-perm (both Ra and Rb)
H-perm (S slice)
the only 4 i have not learnt is the 4 G-perms
also i have learnt some more advanced F2L or first two layers algorithms
after everything, i went to do an average of 12 solves where i got an average of 19.452 average with the fastest time at 14.988 and the slowest at 25.439
perm- permutation. same as algorithms

i learnt that the water in nuclear reactors have much more use thaqn just for boiling to then generate electricity. the water actually allows the nuclear reaction to be more efficient as the water acts as a particle for the nuclear particles to collide into, causing the reaction to be more efficient. another use of water in the reaction of nuclear reactors is thet they can cool down the reactors to prevent overheating.

i learnt how to play a piano piece. i learnt that playing the piano is not an easy thing to do. some of the notes i had to play were quite hard as i had to press multiple keys at once and had to stretch my fingers to reach those keys. although piano may be difficult, it helps me be patient as nothing comes out right the first time. I also learnt that practice makes perfect, we learn from our mistakes and correct them.

I learnt about energy producing roads.The concept involves embedding something called piezoelectric crystals into road surfaces. As vehicles drive over the road, their wheels exert a force that deforms the crystals, causing them to generate electricity. Piezoelectric systems have already been shown to be functional.It is said to have been created due to the worlds growing energy needs.In response, to relieve strain on existing energy sources, innovators worldwide are using new technologies and materials to develop smart roads that can capture,store and redistribute energy whenever and wherever it is needed. Roads surfaced with strong solar panels – known in this application as “photovoltaic cells”– are springing up worldwide. The energy that it stores during the day can be used during the night.The only downside to this is that it will be pricey. Each of Solar Roadways glass solar panels can generate 67 watts of electricity; that energy can be used to power snow-melting heating elements or LED-illuminated road markings and graphics. A microprocessor also facilitates wireless communication between panels and vehicles. However,not everyone is convinced of the effectiveness of solar-panel roads.The weather conditions in the future may not be the same as what it is now. Inclement weather, shade and dirt can interfere with solar capture. Installing the panels on flat surfaces, rather than on an angle as most solar farms do,also limits their efficiency. As i mentioned earlier, the price of the solar roads total to 5 million euros(equal to US $5.6 million). Despite this,many countries are interested in applying the use of solar roads. This is supported by the astounding results that it has already been proven to be able to achieve. This is not only an interesting innovation,it can also be the innovation that just might let our energy sources to last for generations/centuries longer.

i learnt how to make carbonara, which is one of my favourite italian pasta.

firstly, put a pot of salted water to boil.
While the water is coming to a boil, heat the olive oil or butter in a large sauté pan over medium heat. Add the bacon or pancetta and cook slowly until crispy.

Add the garlic and cook another minute, then turn off the heat and put the pancetta and garlic into a large bowl.

In a small bowl, beat 3 eggs and mix in about 1/2 cup of parmesan cheese

Once the water has reached a rolling boil, add the dry pasta, and cook, uncovered, at a rolling boil.

When the pasta is al dente (still a little firm, not mushy), use tongs to move it to the bowl with the bacon and garlic. Let it be dripping wet. Reserve some of the pasta water.

Move the pasta from the pot to the bowl quickly, as you want the pasta to be hot

Toss everything to combine, allowing the pasta to cool just enough so that it doesn't make the eggs curdle when you mix them in.
Add the beaten eggs with cheese and toss quickly to combine once more. Add salt to taste.
Lastly, add some pasta water back to the pasta to keep it from drying out quickly.

during hbl, i learnt a lot about the size of the universe. For example, for light to travel to the moon from earth, it would only take 2 seconds. However, for light to travel to mars from earth, it would take approximately, making instant communication during an emergency impossible, therefore the trip to mars would be dangerous. Also, the farthest man made object from earth is 138 times further away from us than the sun, it is travelling at the speed of 17km/s but even at that speed, it would be unable to break out of the range of our solar system for another 30,000 years. And the closest star from us other than the sun is called Proxima Centauri, and it is located 4.24 light years away from us, light year meaning the distance light travels within a full earth year. And if we drive that distance with a car travelling at a constant 100km/h speed, it would take us 6 times longer than the age of the universe to reach there. We have not even found the true size of the universe yet, because the light from the places had not have enough time to reach us. Therefore it leaves us with an "observerable universe" and according to the theory proposed by alan guth, according to the theory of cosmic inflation, if it happened at 10 to the -37th of a second after the big bang, and the assumption that the universe is the age of the universe X the speed of light, it would suggest that at the present day, the universe is 150 sextillion times larger than the observerable universe, and that the observarable universe would be the size of a light bulb placed in the former planet "pluto" and that we in the light bulb are completely unaware of pluto. This was what i learnt for SIL and for more in depth explanations, here is the link https://www.youtube.com/watch?v=Iy7NzjCmUf0&t=0shttps://www.youtube.com/watch?v=Iy7NzjCmUf0&t=0s.

i learnt about what is a black hole . a black hole is usually formed after a star dies, when the star is dying it expands and then collapses on its self and forms a black hole. not all stars that die become black holes, only those with big mass can become black holes. blackholes can suck everything including light. a black hole will slowly dissapear if they cannot suck gamma rays which is the black holes's source of energy.gamma rays come from stars.black holes can also expand and grow if they are given a abundance of gamma rays.
