What are some scientific discoveries that have changed the world?

 According to Isaac Asimov, the truly important scientific discovery was when Benjamin Franklin published his paper in 1752 stating that "lightning is an electrical phenomenon."

As they say, it's no exaggeration to say that this changed everything. Previous scientific discoveries were only important to other scientists; they had no bearing on humanity as a whole. When Galileo published his geocentric theory, the church opposed it, but it didn't make much of an impression on the general public.

However, Franklin's discovery led to very practical applications.

This is one of Franklin's "lightning rods," a device designed to prevent lightning from striking buildings.

This spread like wildfire, like, "Oh, I don't know, maybe it was lightning?" Within 10 years, churches were the only ones not using lightning rods, because they believed lightning was the work of God and a specific reward from Him. However, after lightning struck a church where gunpowder was stored, (perhaps because God likes churches?) churches also began to adopt them.

The idea that science can solve real-world problems began with lightning rods, and before we knew it, the strange phenomenon of "electricity" came to be used for all sorts of purposes.

For motors that do not require flames,

Bright, inexpensive, and safe lighting,

For extremely fast computers, etc.

Who is the most honest person in the world?

 The Bank of England holds 400,000 gold bars, worth £200 billion (€230 billion). This vault is extremely secure, and no one has been able to obtain these treasures. In fact, these gold bars have not been stolen in 320 years.

However, with the exception of February 16, 1836, the bank executives received anonymous letters. The authors of these letters instructed them to meet "inside the savings vault," where all the gold bullion was located, and to go at a time of their choosing. The astonished executives went to the location that night…

Upon arrival, they found nothing. There was no sound. However, the executives heard footsteps coming from underground. A few seconds later...a man appeared! He was a sewer worker who had accidentally discovered an old tunnel that led directly to the vault. The bank rewarded him with the equivalent of 100,000 euros!

That's a very small reward considering the value of the Bank of England.

Which lake occupies the most unique position in the natural world?

 Lake Itomori, which appeared as a meteorite lake in "Your Name."

What if such a meteorite lake actually existed?

Yes, they exist.

In the New Quebec Crater on Canada's Ungava Peninsula, there is a meteorite lake called Lake Pingaluit.

The name comes from the Inuit word "pingalui," which means "acne."

While any meteorite lake is rare, this lake is considered to have the most beautiful shape of any meteorite lake in the world. Since the release of the movie "Your Name," this lake has become famous for its unique form.

In fact, this lake also holds a special title: it is "one of the clearest lakes in the world ." And for good reason. This lake is actually located about 100 meters above the elevation of the land where the crater is situated. As a result, there are no inflowing rivers, and the water is stored from snow and rain, with few soil particles, so you can see up to 35 meters below with the naked eye.

This crater lake is 3.44 km in diameter and 267 m deep. The meteorite eroded about 100 m of the ground where the crater is located, creating a plateau over 100 m high around the crater. The photo below shows a diagram illustrating the height of the New Quebec Crater.

Water occupies about 70-80% of this depression, making it one of the deepest lakes in North America. With a salinity of less than 3 ppm (compared to 500 ppm in the Great Lakes), it is one of the world's purest freshwater lakes, possessing a unique and precious water quality.

The crater and its surroundings are part of Pingaluit National Park in Canada, which was formed in 2004. Why not see with your own eyes this precious place where Earth's history changed?

What's the creepiest abandoned construction site in the world?

 Well, imagine for fun - or out of necessity - entering the ruins of an abandoned construction site and finding yourself facing two Soviet equivalents of a space shuttle, completely abandoned and freely accessible, with reactors and engines on full display.

This is something that could easily be done in Russia until 2002, the year in which the site where the Buran Program was being carried out was dismantled , the most expensive, ambitious and significant Soviet space project ever, which ended up being miserably abandoned in the early 1990s due to the dissolution of the Union, on which more than 1 million people and approximately 1400 organizations worked, on which a record sum of over a billion rubles was wasted.

What is the largest and busiest airport in the world?

 The largest airport in the world is one. The busiest airport in the world is another. Just because an airport is large or the largest doesn't necessarily mean it's the busiest.

That said, the largest airport in the world is Beijing's Daxing Airport, a brand new one that will open this year. Before the construction of this enormous airport, the record was held by Erdogan's new Istanbul airport. The latter was built in a record time of just five years!

Beijing Daxing Airport. As you can see, it has a very attractive and modern design. But the choice to build it this way was also obviously for improved passenger flow. From the central point of the structure, all piers can be reached in the same time.

This is Istanbul Airport, whose control tower was designed by Pininfarina (below).

The number one airport in terms of passenger numbers is currently Hartsfield–Jackson Atlanta Airport, the capital of Georgia, which I'm reporting below.

Do you know of any "secret" photos from around the world?

What is the strangest island in the world?

 There's a sand island that some strange researchers believe could be a place where aliens conduct research on Earth. Sable Island, a narrow, crescent-shaped sandbar with a surface area of ​​about 34 square kilometers, is located about 300 kilometers southeast of Halifax, Nova Scotia. The island is moving at an average speed of about 200 meters per year, so don't be surprised if its landscape changes overnight.

The island is specifically mentioned in the British North America Act 1867, Section 4, Subsection 91, as a special responsibility of the federal government. Therefore, the island is considered a separate amateur radio entity and is used for operations under the special call prefix CY0. Because the island is a separate radio entity, it has become a popular expedition destination.

Sable Island is a dangerous place for ships. It's estimated that around 350 vessels have been affected by the island's sandbars, earning it the nickname " Graveyard of the Atlantic."

The map shows many of the wrecked ships on the island's coast, with details of the type of ship, name, and year of wreck ranging from 1802 to 1946, although the earliest wreck dates from 1583.

The island's only inhabitants are grey seals and feral horses, which represent one of the last remaining wild horse populations in the world.

The island's moving sand dunes undergo many changes and the landscape can change overnight, so it's possible that aliens chose this place for its strange uniqueness.

What are the greatest engineering blunders in the world?

 In 1990 NASA launched the Hubble Space Telescope worth $1.5 billion (16 billion rn).

After the launch, the scientist found out that there is a microscopic defect of two micrometers (a fraction of a human hair) in its primary mirror. This produced blurry, distorted images.

Even a microscopic defect is a big problem for a space telescope, so in order to fix the error NASA subsequently launched the STS-61 mission.

Basically the mission is about sending astronauts into space using the Space Shuttle Endeavour and fixing the defective optics.

Three years after its launch (1993) the astronauts successfully installed corrective optics, restoring Hubble's iconic vision.

Before and after correcting the lens.

The whole operation cost NASA 900 million to install a corrective lens in orbit to fix it.

Which is the tallest table mountain in the world?

 There are many mountains in the world that have a "tabletop" structure. I will focus on two candidates for the title of the world's largest table mountain.

Mount Roraima : The English explorer Sir Walter Raleigh first described this mountain during his expedition to the area in 1596. It is located at the tripoint of Venezuela, Brazil, and Guyana. The summit area is defended on all sides by 400-meter-high cliffs. Its total height is 2,810 meters, and its summit area is 31 square kilometers. In short, a massive, flat-topped mountain.

Here is another view from above:

The second candidate is Table Mountain , Cape Town, South Africa: The tabletop lies 1,086 meters above sea level. The length of the "table" is approximately 3 kilometers. The image below is the front view as seen from the harbor area of ​​Cape Town.

Table Mountain is certainly not as high as Mount Roraima, and as far as I can tell from my visits, its "flat summit" is no larger than 31 square kilometers. This makes Mount Roraima the largest table mountain.

But it's clear that anyone can easily take the cable car to the top of Table Mountain, or you can hike up, which is what I did. Here's part of the Smuts Trail, which starts in Kirstenbosch Gardens, that I took:

It takes about 1.5-2 hours to reach the summit.

In contrast, climbing to the summit of Roraima requires serious climbing with professionals.

The view from the summit of Table Mountain is spectacular. Here is a view from the top of Table Mountain, with Cape Point in the distance. Note the causeway at the summit of Table Mountain. This picture was taken near the Maclear Lighthouse, the highest point of Table Mountain.

Our hike began in Kirstenbosch Gardens, following the Smuts Trail. Here's a view from above of Cape Town and Signal Hill:

And finally, a view of Camps Bay on the Atlantic side:

In summary, Roraima is the largest flat-topped mountain in the world, measured by the height and extent of its tabletop, but Table Mountain, while the second largest and second highest mountain in the world, can be easily experienced by everyone, either by hiking or taking the cable car to the summit!

What is one of the most unsolved mysteries in world history?

 There are many figures to consider, but I'd like to introduce you to Rasputin, the Russian scientist who is perhaps the most enigmatic figure in modern Japanese history .

He always looks scary in photos, but he's seriously come back to life about 10 times .

His life began in a small village in Siberia. Apparently, because literacy rates were low in his village, he didn't attend school and instead spent his time playing around.

After getting married, he suddenly told his family he was going on a pilgrimage and left the village. Apparently, he had received a revelation from the Virgin Mary. After completing his training and returning to the village, he had become a devout ascetic.

He then went to the capital city of Saint Petersburg and, with his mysterious powers, he healed people's illnesses one after another, earning him the title of "Man of God ." His reputation reached the ears of the emperor, who asked him to cure the crown prince's hemophilia. Although it is still a difficult disease to treat even today, he miraculously succeeded in curing the crown prince's hemophilia . This event earned him the emperor's trust. Incidentally, there are various theories as to why the hemophilia was cured, but ultimately it remains a mystery.

Because of all this, he enjoyed the emperor's absolute trust, and he was also very popular with the surrounding nobles. He lived surrounded by many noblewomen who thought that if they could get the same benefits from his virility, they would too. Naturally, some people became suspicious of him, and voices calling him a "charlatan" and a "heretic" rose from all sides. He was nearly assassinated by people who thought he would start manipulating the emperor's power from behind the scenes. He was stabbed in the abdomen by the assailant, but he fought back with a stick that was nearby . He survived and recovered after spending seven weeks in the hospital (lol).

Nevertheless, the number of people who found him suspicious continued to grow, and when World War I began, the nobles around him started spreading rumors to bring him down. And once again, his life was in danger.

On December 17, 1916, he was assassinated at Moika Palace. Rasputin had been invited to a party by the assassins, and initially, the assassins mixed potassium cyanide into his cake and tea. However, he remained completely unfazed and continued to converse normally . As the party drew to a close, the assassins, seeing that he was not dying, decided to kill him with a revolver. They fired two shots at the drunken Rasputin from behind, but he fell once before getting up again, reportedly saying, "I opened my eyes and realized I was in danger ." Hearing the commotion, the other assassins fired more shots at him, one of which pierced his spine, yet he got up again. Shocked a second time, the assassins finally lost patience, struck him in the right eye with a candlestick, and shot him in the forehead, finally killing him . Incidentally, his body was thrown into a river.

Following this assassination, the emperor was overthrown and executed, and a new country, the Soviet Union, was established.

That concludes his life story. Finally, I would like to summarize his legends, including those that I couldn't include above.

• He cured the Crown Prince's hemophilia with a mysterious power.
• He didn't die from potassium cyanide.
• He didn't die even after being hit by several bullets.
• He finally died after being punched and shot in the forehead.
• The strength to still swing a stick even after being stabbed.
• As a child, I nearly drowned in a river and contracted pneumonia, but I survived.
• Despite liking sugar, he never brushed his teeth and had a mouth full of cavities.
• He could make any horse docile during training.
• I was able to lift things using hypnotic powers.
• He was indifferent to money and often gave it away to others without hesitation.
• He had a monstrously huge penis.

He's truly a strange monk .

Why are mathematicians not among the richest in the world?

 In the 1980s a mathematician walked into Wall Street and completely changed the game. He wasn't a famous trader. He wasn't a celebrity investor talking about intuition, leadership or reading annual reports. He was a simple mathematician named Jim Simons.

Source: X

While everyone else was trying to understand the market through stories, Simons treated it like a giant puzzle. Most investors asked questions like: "Is the company well managed?" or "What will the economy do next?" Simons asked a different question, "What patterns keep appearing in the data, whether people notice them or not?" That question became Renaissance Technologies and eventually the legendary Medallion Fund, arguably the most successful hedge fund ever created.

Simons didn't build his team with Wall Street veterans. He hired mathematicians, physicists, statisticians, astronomers, and cryptographers. People trained to find signals hidden inside noise. The fund was powered by thousands of tiny statistical edges. A small pattern in currencies. A slight delay in commodity prices. A recurring behavior that appeared just often enough to be useful. Individually, those patterns looked insignificant. Combined together, they became a machine that generated extraordinary returns for decades.

There is no relation between smartness and money. Smartness makes you earn money with least hard work, so as to keep yourself healthy and happy but it also teaches you money isn't everything. Look back at history you can hardly tell a mathematician who was millionaire, they do mathematics because the like it.

Which records in cricket are unlikely to be broken ever?

 Getting out, after scoring Triple Centuries (in tests ), on the same date twice!!

There are many records which are unlikely to be broken because of the magnitude of it. Well, this one is going to be much more difficult to break for sure.

Scoring a triple century in test cricket is not at all a common feat. Only 30 triple centuries have been scored till date in the entire test cricket history ( by 26 different batsmen ). The frequency of a batsman scoring a Test triple century is slightly less than that of a bowler taking a Test hatrick, according to wikipedia.

And,

For the same batsman to score 2 triple centuries in his career is obviously a rarer phenomenon. Only 4 players have achieved this landmark in tests, namely, Donald Bradman(Australia) , Brian Lara(West Indies), Chris Gayle(West Indies) and Virender Sehwag (India).

And then,

To score them is one thing but to get out on the same dates after doing so !!. Well, it is some coincidence, isn’t it ?

Date : March 29

And,

The man who scored these peculiar triples??

None other than the ‘Nawab of Najafgarh’, Virender Sehwag.

The first one came against Pakistan at Multan in 2004. The test began on 28 Mar 2004 and sehwag reached his triple after lunch on Day 2 , before losing his wicket on 309.

Date he got out : March 29, 2004.

India eventually won the match by an innings and 52 runs, thanks to Viru’s maiden triple !

The second one was against a world class opposition in South Africa. The test began on March 26, 2008 and South Africa were the first to bat. They posted a huge total of 540 before getting all out near the end of day 2. Sehwag scored 284 runs the following day and scored his 2nd triple, becoming only the fourth player to do so. In the first session of Day 4, while on 319 Sehwag was caught at slip, only to get a standing ovation from the Chennai crowd, who were thoroughly entertained.

Date he got out: March 29, 2008

India had to wait for more than 12 years to see someone other than Sehwag to score a triple century for the nation. Karun nair recently scored a triple century against England, becoming only the second Indian to achieve the feat !

Given the rarity of a triple century in test matches and the strange nature of this record, I think Virender Sehwag may remain as the only player to score 2 triple hundreds and get out on the same date in both of them, for years to come.

Long live, The Nawab Of Najafgarh !!
