The Sagrada Familia, Antoni Gaudi's masterwork, began building in 1882 and has continued under development ever since. Gaudi was never able to see his masterpiece completed. After 144 years of development, Barcelona hopes to have it finished by 2026, the 100th anniversary of Gaudi's death.

Without mentioning the city's diverse population, no list of interesting facts about New York is complete. The city's residents speak roughly 800 different languages collectively. Almost half of New York households speak more than one language, and one-third were born outside of the country. And, because New York has the most people of any city in the United States, one in every 38 people in the country is a New Yorker.

A Formula 1 race car's engine is not like one found in a Toyota that can go 200,000 miles without breaking a sweat. A normal Formula 1 engine, according to F1Technical, can only endure seven races. The competitors set aside a considerable sum only for engine development. The tolerance and capability of F1 engines are unparalleled. They're designed to get the most out of them, even if that means just operating for a few hours. Because the engines are built with such accuracy, they are more prone to wear and tear.

Guinness World Records certified the mixed-use hotel and office complex as the World's Farthest Leaning Manmade Tower in 2010. The lean of the Capital Gate structure is 18 degrees, which is more than four times that of Italy's famous leaning Tower of Pisa.

Despite saying that there was only one Batman in the world, there was no true news about it after that. Batman originally debuted in a comic book in 1939. The issue is, which came first, the chicken or the egg? Which came first, the chicken or the egg?

Ecologists estimate that treating one ton of ore yields 1–2 grams of gold. The same quantity of precious metal may be obtained by processing all gold-bearing components from 41 mobile phones. A tonne of electronics includes almost 300 grams of gold. However, the cost of the devices is prohibitively expensive for this gold-mining method to be profitable.

The world we "see" is a figment of our imagination. Our minds do not generate images in the same way that a video camera does. Instead, the brain builds a model of the world using data from modules that measure light and shade, edges, curvature, and so on. This allows the brain to easily paint out the blind spot, which is the area of your retina where the optic nerve connects and has no sensors. It also compensates for our eyes' rapid, jerky movements, known as saccades, creating the illusion of steady vision.

Sechs Kies is South Korea's most established idol group. The band was founded in 1997 with six members and currently has five active members. Some may not consider them the longest because they were on hiatus for more than ten years; however, the longest-lasting idol group could also be considered Shinhwa, who debuted in 1998 and has been promoting consistently for the past 20 years.

In 2012, when Boeing wanted to test its wireless signal on new planes, they placed massive piles of potatoes on the seats. Potatoes absorb and reflect radio and wireless signals in the same way that humans do due to their high water content and chemical makeup.

The entire ban was based on the discovery of a picture of a swastika-adorned Pooh owned by a single person known for supporting the Nazi party. That was apparently enough to get Winnie banned for good.

Malaysia is home to the world's biggest cave chamber. The Sarawak Chamber at Gunung Mulu National Park is enormous, with enough capacity for 40-50 Boeing 747s. It's another matter if you could actually park these jets in the Sarawak Chamber...

As if the Nazis weren't already evil enough, they got dangerously close to producing plutonium, the material that powers nuclear bombs. When the Germans invaded Norway, they seized control of a facility in the Telemark region that manufactured heavy water, which was used to generate plutonium. However, before they could create anything, a group of 11 Norwegian commandos damaged the factory, detonating explosives in the base without incurring a single death.

The Nazis pondered releasing an army of potato bugs on their adversaries, which they felt might be dumped on England to ruin its crops and bring severe starvation.

Although yellow is widely regarded as a mood-enhancing colour, it is not recommended as a primary colour scheme. According to studies, rooms with too much yellow may cause people to lose their tempers more easily.

Edison was, without a doubt, one of the world's most renowned intellectual property thieves. He stole nearly all of the 1,093 things he smashed a patent on from real geniuses like Nikola Tesla, Wilhelm Rontgen, and Joseph Swan – the latter of whom invented the lightbulb!
