Chess Grandmaster Anna Muzychuk refuses to play in Saudi Arabia and says: "In a few days, I will lose two world titles, back to back." Because I decided not to go to Saudi Arabia. I refuse to play by special rules, to wear abaya, to be accompanied by a man so I can leave the hotel, so I don't feel like a second class person. "I will follow my principles and not compete in the World Fast Chess and Blitz Championship where in just 5 days I could have won more money than dozens of other tournaments combined." This is all very nasty but the sad part is no one seems to care. Bitter feelings but can't go back. "

Judy was a special pointer dog who lived on navy ships in the Pacific Ocean. In 1942, the Japanese captured her and put her in a prison camp. There she met a man named Frank Williams, who shared his small bit of rice with her even though he was very hungry too.
Judy made the prisoners feel happier during the tough times. She would bark loudly when dangerous snakes, crocodiles, or even tigers came near the prisoners. When the prisoners had to go on a ship back to Singapore, Frank hid Judy in a rice sack. She stayed super quiet and didn't make a sound, so the guards never knew she was there.
The very next day, their ship was hit by a torpedo! Frank pushed Judy out of a small window to try to save her. There was a big 15-foot drop to the ocean below. Frank escaped too, but was caught again and sent to a new prison camp.
Frank didn't know if Judy survived. But then he heard stories about a dog helping people who were drowning after the ship sank. When Frank got to the new camp, something amazing happened. "I couldn't believe my eyes! As I walked through the gate, a scraggly dog hit me square between the shoulders and knocked me over. I'd never been so glad to see the old girl!"
They spent a whole year together at the camp in Sumatra. "Judy saved my life in so many ways," said Frank. "But the greatest of all was giving me a reason to live. All I had to do was look into those weary, bloodshot eyes and ask myself: 'What would happen to her if I died?' I had to keep going."
When the war ended, Frank smuggled Judy onto a ship going to Liverpool, England. In England, Judy got a special medal called the Dickin Medal, which is like a medal of honor for animals. She got it for being brave and helping prisoners stay hopeful.
Frank also got an award for taking such good care of Judy. For a year after the war, Frank and Judy visited families of prisoners who had died. Frank said that Judy "always provided a comforting presence to the families."
When Judy died at 13 years old, Frank spent two whole months building a beautiful stone memorial for her. It had a special plaque that told Judy's amazing life story.

I’m sure that you, our dear Pandas, are curious to know about the rest of the types of knowledge I teased you about above. So that’s exactly what we’re going to talk about from this point. According to Guru, an all-in-one knowledge management base, there are 16 types of knowledge in total.
But before we dive into some of them, we should probably define what knowledge itself is. According to the Cambridge Dictionary, knowledge is “understanding of or information about a subject that you get by experience or study, either known by one person or by people generally.”

Robin Williams once brought laughter back to a grieving gorilla who had been mourning the loss of his friend for six months. This remarkable story began when American ethologists taught a gorilla named Koko to communicate with humans using sign language. Koko was exceptionally intelligent, but he was going through a deeply difficult period, to the point where biologists feared he might be suffering from severe melancholy.
The researchers wanted to help Koko by finding him a new companion while also studying how he interacted with humans. Since Koko had learned sign language and could communicate with our species, he was the perfect subject to explore whether there were true cognitive boundaries between humans and gorillas. To assist, they reached out to Robin Williams, the renowned comedian, and asked if he would spend time with Koko, interacting with him naturally, as if he were simply a person in need of comfort.
Williams agreed, though he had reservations. He wasn’t an expert on primates and worried he might be too awkward to connect with the gorilla. However, when he met Koko, Williams had an unexpected revelation. By letting the gorilla approach him at his own pace, Williams realized that interacting with Koko felt like engaging with a curious child. Gradually, Koko grew more interested in his visitor, even becoming fascinated by Williams’ glasses, which he referred to as "strange glass eyes."
Soon, Koko began communicating with Williams through sign language, suggesting games and asking surprisingly insightful questions that left the actor stunned. Within minutes, the two were joking, tickling each other, playing, and sharing stories from their lives. The researchers were amazed and asked Koko to describe Williams in one word. The gorilla chose the term "friend." Williams was deeply moved by the encounter, especially when he learned that he had managed to make a gorilla laugh who was on the brink of depression due to loneliness.

The little girl in this photograph is Ruby Crane. From the young age of 3 years old, she spent her days at St Dunstan’s Rehabilitation Centre in Brighton, Sussex—helping blinded soldiers returning from World War I. Ruby’s father was the head gardener, and as she wandered the grounds, she would take the soldiers by the hand and guide them to their workshops, asking where they wanted to go. She knew they couldn’t see and just wanted to help. Her kindness deeply moved those around her. People sent dolls and toys to thank her for the support she gave to the men and women who had lost their sight. Ruby was so beloved that she was featured on the front page of St Dunstan’s first Annual Report (1915/1916), and later, Flag Day emblems were designed in her honor.
Years later, Ruby recalled:
"I always remember how my little hand seemed so small in their big hands… They were so pleased to have a child come and talk to them. It was something different—away from the monotonous grind of not being able to see things, I think."
Ruby was rewarded with a long life, passing away in 2011 in her late nineties. But her legacy of kindness lives on. ❤️

This is the final photo of Saman Kunan, a 38-year-old former Thai Navy SEAL who gave his life during the daring rescue of twelve boys trapped in a flooded cave in Thailand.
When he learned the boys were running low on oxygen, he made the ultimate choice—leaving his own supply behind to give them a better chance at survival, and setting out to bring more. Tragically, he never made it back.
His bravery and sacrifice helped pave the way for the boys’ eventual rescue—and he is remembered as a true hero.

As already mentioned, knowledge isn’t monolithic and has various forms, which are only increasing in number, as digital platforms and big data are evolving and changing the way we can access knowledge.
The three main types of knowledge are explicit, implicit, and tacit. The primary difference between them is how they are obtained from our surroundings. Explicit knowledge is written down, codified, and shared, which makes it widely available. It’s logically structured, objective, and technical, and can be found in manuals and guides, academic papers, and databases.

Tucked quietly along a street in Barcelona, there stands a sculpture that stops people in their tracks.
It’s called The Abandoned Dog, created by Catalan artist Artur Aldomà Puig.
No pedestal. No glory. Just a dog—sculpted in stone, sitting alone, waiting.
Its eyes are what pull you in.
Wide. Hopeful. Full of quiet sorrow.
It’s not just a statue—it’s a message.
This sculpture is a tribute to every dog who gave their love, only to be left behind. It speaks for the voiceless. The loyal. The forgotten.
Next to the figure is a poem by the artist himself, etched in metal.
It reads:
“Your race doesn’t matter.
Your name doesn’t matter.
You came into the world
to be my friend.”
It’s not just about dogs. It’s about what we owe to love—the love that comes without judgment, without condition, without limit.
Locals leave flowers by its paws. Children stop to pet it. Visitors kneel to take photos and wipe away tears. It has become a place of memory, and mourning, and quiet promises.
A reminder that loyalty like this should never go unnoticed.

Passengers flying first class on British Airways’ Boeing 747s have expressed concerns about a redesign that includes windows in some lavatories. One woman traveling to New York voiced her discomfort over the lack of blinds. A stewardess reportedly responded, “Madam, if someone is clinging to the side of this aircraft at 35,000 feet, they’ve earned the view.

Meanwhile, we gain implicit knowledge through personal experiences, like social interaction, mentorship, or collaboration. It’s not formally documented or written somewhere since it’s acquired in the real world through actions and practices. Tacit knowledge is even harder to express, as it involves insights, intuition, judgment, and skills learned over time. An example of this could be the feeling when you know that the bread’s consistency is right when baking.

On a cold morning in 1857, in Dundee, Scotland, a girl was born who would one day light up the universe—not with a telescope, but with brilliance. Her name was Williamina Paton Stevens Fleming.
From an early age, Williamina showed a mind far beyond her years. By 14, she was already teaching. But life took an unexpected turn when she married, moved to the United States, and was abandoned—left alone with her child in a foreign land.
With limited options, she took a job as a housekeeper in the home of Edward Pickering, director of the Harvard College Observatory.
Fate works in mysterious ways.
Legend has it that, frustrated with his staff, Pickering once shouted, “My Scottish maid could do better!” What began as sarcasm became a spark of destiny.
In 1881, he gave Williamina a chance—and she stunned everyone. With no formal scientific education, she began analyzing photographs of the night sky with unmatched precision. She became the first of the Harvard Computers—a group of brilliant women behind some of astronomy’s greatest breakthroughs.
Williamina went on to:
Classify over 10,000 stars
Discover 10 novas, 59 nebulae, and 310 variable stars
Create the Harvard Classification System, which laid the foundation for how we categorize stars to this day
She also became the first American woman to be named an honorary member of the Royal Astronomical Society—a historic achievement in a male-dominated field.
Her work didn’t just study the stars. She became one.
Williamina Fleming proved that greatness can come from the most unexpected places. That brilliance doesn’t need permission—and that a determined woman can change the very way we see the universe.
Her story continues to inspire dreamers and trailblazers to this day.

After the devastating earthquake and tsunami in 2011, when the Fukushima nuclear power plant was on the verge of collapse, a small group of people stepped forward – not soldiers, not politicians, but courageous technicians, engineers, and scientists. Many of them were already retired. They volunteered to stay where few wanted to stay: inside the danger.
With destroyed cooling systems and radiation levels thousands of times higher than the legal limit, these men and women risked their lives to prevent the worst. They became known worldwide as the "Fukushima 50."
Equipped with protective suits, they took on tasks no machine could do – pumping seawater into overheated reactors and working amidst the rubble. They knew what was at stake: not just their health, but the fate of an entire country.
What they did was not heroism in the traditional sense. It was quiet courage, deep responsibility, and the will not to look away in the darkest hour. Many of them didn't want recognition—only the hope that their efforts would save lives and prevent the unimaginable.
Their courage will never be forgotten.

The possession of such knowledge allows us to understand, recall, and state facts, concepts, or general facts.

He bought a dead island for 13 thousand dollars, equipped the island with endangered animals, birds and trees. They offered 50 million dollars, he did not sell it and donated it.
In 1962, newspaper editor Brendon Grimshaw bought the uninhabited island of Moyenne in the Seychelles, where no human had set foot for 50 years, for 13 thousand dollars.
He began to live on the island like a real Robinson, taking with him companions from the locals.
His name was "Rene Lafortin".
Brendon and Rene started to equip the island.
Over 39 years, Brendon and Rene planted 16 thousand trees with their own hands and built approximately 5 km of road.
In 1996 he wrote a book about himself and the island called Grain of Sand. A documentary of the same name was made about Grimshaw and the island in 2009.
In 2007, Rene Lafortin died and Brendon was left alone on the island. He was 81 years old.
During his lifetime, he attracted 2000 new bird species to the island and introduced more than a hundred giant tortoises to the world, which were about to become extinct, including the Seychelles.
Thanks to Brendon's efforts, the once deserted island is now home to two-thirds of the Seychelles fauna. An abandoned piece of land turned into a real paradise.
A few years ago, the prince of Saudi Arabia offered Brendon Grimshaw $50 million for the island, which Brendon politely declined.
“I don't want the island to become a favorite vacation spot for the rich.
"Let it be a national park where everyone and animals can live and have fun freely."
He finally achieved his wish. In 2008, the island was indeed declared a "National Park". Grimshaw was the sole resident of the island until his death in July 2012. "Wanting" is not just about saying "I want".
You can achieve results by doing what you can afford, step by step, sometimes for years. Never expect such a thing from children who have been accustomed to being ready since childhood, or do not accustom your children to being so ready so that they can learn to make the world a better place.

In 1963, at the age of 31, Dian Fossey used her entire life savings and took out a bank loan equivalent to one year's salary to fulfill her lifelong dream of traveling to Africa. After her trip, Fossey -- who was born on this day in 1932 -- was determined to permanently relocate there and dedicate her life to studying the shy and reclusive mountain gorillas, whose population was teetering toward extinction.
Following her first seven-week safari through Kenya, Tanzania, and the Democratic Republic of Congo, Fossey returned to Louisville, Kentucky where she had been working as an occupational therapist. There, she encountered anthropologist Louis Leakey when he was on a lecture tour and he suggested that Fossey start a long-term study of mountain gorillas. Similar to how he helped support Jane Goodall begin her study of chimpanzees in Tanzania, Leakey helped line up funds for Fossey's project and she left to establish the Karisoke Research Foundation in a remote rainforest in Rwanda in 1967.
Fossey ran an extensive study of mountain gorillas for 18 years and was considered the world's leading expert and a fierce protector of these "gentle giants." After one of her favorite gorillas, Digit, was k****d by poachers in 1977, Fossey created the Digit Fund, now the Dian Fossey Gorilla Fund International, to fund anti-poaching efforts. Fossey and her colleagues devoted significant attention to anti-poaching activities, including running poaching patrols, destroying poacher's traps, pressuring local authorities to enforce anti-poaching laws, and helping in the arrest of poachers.
In 1983, she published a book based on her experiences, "Gorillas in the Mist," which became a bestseller and was turned into an Oscar-nominated film starring Sigourney Weaver. Tragically, Fossey was k****d in her cabin in the Virunga Mountains of Rwanda in December 1985. Although the case has never been solved, it is widely believed that she was k****d by a poacher in response to her aggressive anti-poaching efforts.
Dian Fossey left behind an amazing legacy – both one of greater knowledge about these previously poorly understood animals and one of inspiration which has motivated many people to join the fight to save the critically endangered mountain gorillas. As her final diary entry read, "When you realize the value of all life, you dwell less on what is past and concentrate more on the preservation of the future."

In contrast, procedural knowledge involves exercising the knowledge you have to perform a task. It often takes the form of how-to tutorials in which a task is broken down into steps or a sequence of actions. Meanwhile, a posteriori knowledge, also known as empirical knowledge, is gained through observation or experimentation. The word empirical in its name suggests that this knowledge relies on data and real-world evidence to form conclusions. This kind of knowledge is especially essential in scientific research.

In the myths of King Arthur, the legendary sword Excalibur was gifted by the Lady of the Lake, emerging from the waters to choose its rightful wielder. But in 2018, life imitated legend when an 8-year-old girl named Saga Vanecek pulled an actual ancient sword from a lake—stunning historians and capturing the world’s imagination.
Saga, a Swedish-American girl, was playing in the waters of Lake Vidöstern in southern Sweden, where her family had a summer home. The lake had receded due to a drought, exposing parts of the muddy bottom. As she waded through the shallows, her hand brushed against something long, thin, and sharp.
At first, she thought it was a stick or an old piece of metal, but when she lifted it from the water, she realized it had a hilt and a blade—it was a real sword.
Excitedly, she ran to her father and said, "Daddy, I found a sword!"
What she had discovered was not just any sword—it was a 1,500-year-old relic from the pre-Viking era, dating back to the 5th or 6th century. Experts from the Jönköping County Museum confirmed that the blade was remarkably well-preserved, complete with its wooden scabbard and leather straps.
Swedish media quickly nicknamed her “The Queen of Sweden,” joking that she had fulfilled the Arthurian prophecy. The discovery was so rare that archaeologists searched the lake further and even found other ancient objects nearby, suggesting the site may have been a ritual offering place in ancient times.
Despite the fairy-tale comparisons, Saga took her newfound fame with humility, saying:
"I didn’t want to be a queen. I just wanted to be a scientist or an archaeologist."
The legend of Excalibur may be a myth, but Saga Vanecek’s story is real. A young girl, a hidden lake, and a sword lost in time—sometimes, history has a way of writing its own fairy tales.

"I didn’t want to be a queen. I just wanted to be a scientist or an archaeologist."
The legend of Excalibur may be a myth, but Saga Vanecek’s story is real. A young girl, a hidden lake, and a sword lost in time—sometimes, history has a way of writing its own fairy tales.

Did you know Sable Island is a narrow, remote sand island located in the Atlantic Ocean, off the coast of Nova Scotia, Canada. Known for its crescent-moon shape, the island is famous for its population of wild horses, which live freely, and its unique ecosystem, which includes various bird species and plants adapted to its windy and arid climate. It's also recognized for its history as a big-movie “cemetery of shipwrecks,” due to the shallow sandbanks surrounding it. Currently, it is a protected nature reserve and an environmental research site.
A fun fact about Sable Island is that it has more wild horses than human inhabitants. These horses, descendants of animals brought in the 18th century, survive in complete freedom and have adapted to the extreme surroundings of the island.

Barbara Harmer left school at 15 without any qualifications and started working as a hairdresser. After five years of styling hair, she decided to apply to become a trainee air traffic controller at London Gatwick Airport. While at Gatwick, she also chose to study for her A levels, aiming to pursue law, focusing on Geography, English Law, and Constitutional Law. However, she later switched gears and began taking flying lessons after getting a £10,000 bank loan.
Once she earned her private pilot license, she started a two-year distance learning course for her commercial pilot license, which she achieved in 1982. Even after that, her determination was really put to the test when she faced rejection from potential employers. She sent out 100 applications for pilot jobs, and all of them were turned down.
In 1984, after two years on the tarmac, she landed her first pilot job with a small commuter airline. That same year, fortune smiled upon her when she joined British Caledonian Airlines. Things got even better for her in 1987 when British Caledonian Airlines merged with British Airways. She kept flying high, and after four years flying British Airways' DC-10, she was chosen to train as a Concorde pilot, making her the first woman qualified to fly the supersonic aircraft.
By the time Concorde was retired in October 2003, Harmer had spent 10 years as a pilot for regular scheduled services. After Concorde, she transitioned to flying the Boeing 777 Jumbo jet until she voluntarily retired in 2009 to explore new adventures. She had plans to sail her yacht across the Atlantic in 2013, something she was already preparing for.
Sadly, unbeknownst to her, she had developed ovarian cancer, which was slowly taking a toll on her health. By the time it was diagnosed, she had just over a year to live. Captain Harmer, who never had children, passed away in 2011 at the age of 57, leaving behind her husband of 27 years. Her ashes were flown high and scattered over the sea near her home.
Starting from humble beginnings, she climbed to incredible heights. Her legacy continues to inspire women and young people everywhere. With her practical, can-do attitude, she achieved remarkable success in a male-dominated field.

Another quite interesting type of knowledge that also challenges a posteriori knowledge is a priori, which exists independently of experience and is solely based on reasoning or logic, without needing empirical evidence or verification. This includes mathematical truths and universal principles that don’t require validation. Just like the mathematical equation two plus two, and conceptual truths like all bachelors are unmarried.

This photo was taken by a Turkish photographer when a goat gave birth to a baby on an icy mountain. To save the life of the goat and the baby, a village girl (shepherdess) carried the mother on her shoulder and the girl's dog saved the newborn goat by carrying her too. This photo is a living example of humanity.

She got married at the age of 14, and at the age of 20, she became a single mother. The first female millionaire who made a fortune with her 10 fingers. She entered the Guinness Book of Records as the first woman to become a millionaire independently, without inherited money.
Sara Breedlove was born in 1867 in the south of the USA, in the state of Louisiana. Her parents, older brothers, and sister were slaves in the cotton fields. But Sara was born free. When she was 7 years old, she lost her parents. After her parents died, she moved in with her sister and her husband. As a child, Sara worked as a housekeeper and did not have time for schooling. She later shared that she only had 3 months of formal education when she attended Sunday school.
She was only 14 when she married Moses McWilliams. She didn't do it because she loved him. The truth was that her sister's husband was a very violent man, and marriage was the only way for Sara to escape from that family. Four years later, Sarah and Moses had a daughter, Alleluia. Two years later, Sarah's husband dies. So Sara became a single mother and a widow at the age of twenty.
In 1888, Sara moved to St. Louis. Her brothers worked there as barbers. She started working in a laundromat and as a cook to pay for her daughter's education in a public school. Sara earned about $1.50 a day.
Like all the workers in the laundry, Sara got sick from chemicals: skin disease, lack of water, and heating in the house made Sara almost lose her hair. Thanks to her brothers, she learned the basics of hair care. A little later, Sara learns about the Eni Malon series of hair products and later meets Eni in person. He starts selling her products on the street.
Still working for Malon, Sara, now at the age of 37, moves to Denver with her daughter and begins to think about her own line of cosmetics for African-American women. After many experiments, she succeeds. He starts building his own business.
In 1906, Sara married Charles J. Walker and later became famous under his surname. Charles becomes her business partner: He does advertising and helps his wife with promotion.
Sara went door to door trying to sell her products, but also to teach women how to care for and style their hair. In the same year, Sara decided to expand her business, so she and her husband traveled around South and East America. Her daughter had grown up and graduated from school, so she helped her mother with all the shipments from Denver.
Two years later, Sara moved to Pittsburgh. The family opens a beauty salon, but also a school that trains people to know everything about hair care so that they can apply Sara's products.
In 1910, Sara moved to Indianapolis, where she opened the headquarters of the company Madam C. J. Walker.
He builds a factory with a laboratory, a hair salon, and a beauty school where he teaches his sales agents. By 1917, Mrs. Walker employed about 20,000 women. Her agents earned from 5 to 15 dollars a day. Sara wanted African-American women to be financially independent, so she encouraged women to open their own businesses and taught them how to handle money.
The richer she became, the more time she spent on charities and giving. She gave lectures, fought against social injustice, and donated money to funds. Before she died, she donated more than 100,000 dollars to the poor and various organizations and social institutions.
In her will, she stated that 2/3 of her future profits should be given to charity. She died at the age of 51. She was considered the richest African-American woman. When she died, her fortune was thought to be between $500,000 and $1 million. During her lifetime, Sara was not a millionaire, only 2 years after her death, her wealth increased, but while she was alive, she hoped that she would be. And not because she needed the money, but because she wanted to do more good deeds.
