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.

Christian Dior technically invented designer sunglasses when, in the early 1960s, they licenced their brand to be used to produce luxury sunglasses for discerning fashionistas. Using Optyl, his own lightweight thermo-hardening material, he converted expensive sunglasses into more wearable everyday items. The properties of this material also allowed for a wider choice of models, from broad and original lines to previously discovered hues and delicate degradé of translucent, brown, green, and grey colours that still mark Dior's beautiful and refined style.

Muammar Gaddafi took power in Libya in 1969 and reigned for 42 years. As a result, he became one of Africa's and the world's longest-serving leaders of state.

He also boosted Libya's literacy rate from 25 percent to 87 percent during his tenure. When he was removed from power in 2011, his reign came to an end. The militia hunted him down and murdered him in his hometown, where he had sought safety. Gaddafi's net worth was $200 billion at the time of his death.

The total weight of this heavy lock, including the key, is 916 pounds. Whatever it's guarding presumably weighs a lot more!

The Tonle Sap supports about half of Cambodia's agriculture and is a key fishing source. The incredible thing about this lake is that it regenerates in major areas throughout the rainy season, when monsoon rain pours and floods the centre area between Siem Reap and Phnom Penh.

The first hot air balloon was launched in 1783, transporting a sheep, duck, and rooster. In France, the Montgolfier brothers created the hot air balloon. They began experimenting with balloons after witnessing the heat of a fire raise their drying clothing. Because it was uncertain how flying at such altitudes might impact humans, the initial flight included animal passengers. The flight was a perfect success, and the animals arrived safely and largely unscathed. The sheep, however, managed to land on the rooster.

USA's present 50-star flag was created by 17-year-old Robert Heff as part of a high school project. It was 1958, and there were only 48 states at the moment, but Heft had a feeling Hawaii and Alaska would get statehood shortly. His teacher gave him a B- but later raised the mark to an A after Heft submitted his design to the White House, resulting in a call from President Eisenhower announcing that it had been chosen as the official U.S. flag.

In Korea, age is given precedence over all other considerations. When conversing with someone of a higher rank or age, formal language must be used. Similarly, when conversing with a junior/someone younger, you can use informal language (banmal, ). Unless two people agree to use banmal at the same time, this usually remains the case. Even in a k-pop group with members who are mostly around the same age, a few months difference in birthdate can make a big difference.

Did you realise that the word "Pennsylvania" is misspelt on the Liberty Bell? Actually, worded incorrectly is perhaps a bit harsh: when the bell was constructed in 1752, it was one of several permissible spellings. The ancestors of the United States also committed several obvious language errors in the Constitution.

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.

Many people find this assertion odd, yet eating pizza for breakfast is really healthier than eating cereal. According to famous American nutritionist Chelsey Amer, pizza includes lipids, carbs, and protein that will keep you fuller for longer than porridge with milk. Cereals, of course, include carbohydrates and sugar. Of course, this does not mean that you should only eat pizza for breakfast, but it also does not mean that you should only eat cereal in the morning.
