Deep True Facts

On March 27, 1977, two Boeing 747 passenger jets, KLM 4805 and Pan Am 1736, collided on the runway at Los Rodeos Airport (now Tenerife North Airport) in Tenerife, Spain. The crash, which killed 583 people, was the deadliest in aviation history. A terrorist attack at Gran Canaria airport diverted many flights to Los Rodeos, including two downed planes. The airport was soon full of parked planes, blocking a single taxiway and directing departing planes onto the runway. Dense fog covered the airfield, greatly reducing the visibility of pilots and control towers. The accident happened when the KLM plane was taking off. The Pan Am plane was still on the runway, shrouded in fog, and about to enter the taxiway. The impact and associated fire killed everyone aboard KLM 4805 and most of the crew of Pan Am 1736, leaving only 61 survivors at the front of the plane. A subsequent investigation by Spanish authorities determined that the main cause of the accident...

In December 1937, a football match between Chelsea and Charlton Football Club at Stamford Bridge Stadium in London was suspended after 60 minutes due to heavy fog. Legendary Charlton goalkeeper Sam Bartram continued to defend the goal after 15 minutes of play, unable to hear the referee's whistle due to the crowd behind the goal. He sat with his arms outstretched and focused, so as not to be surprised by the enemy's attack. Fifteen minutes later, when the ringside police approached him and informed him that the match had been stopped, Sam Bartram said: Bartram thought his team attacked and did not allow the other team access to the goal.

One of the rarest blood types in the world is Rhnull, also called "golden blood". People with this blood type do not have the Rh antigen at all. First discovered in Australian Aborigines, this blood is extremely rare, with fewer than 50 people known to have Rhnull blood in the 50 years since its discovery. Its rarity means that Rhnull donations are rare and difficult to obtain when an Rhnull person needs a blood transfusion, and we rely on the cooperation of a small network of regular Rhnull donors around the world to ensure that blood types are always available when necessary. Interestingly, for reasons not well understood by scientists, not all "foreign" antigens can be targeted for antibody destruction. There are a total of 36 blood types, but there are certain blood types that doctors and patients should pay attention to when transfusing. For example, AB0 antibodies are almost always clinically important. Other blood types th...

Caffeine is a common ingredient in medications to treat or control sleepiness, headaches, and migraines. Studies have shown that regular coffee drinkers have a lower risk of developing Alzheimer's disease and dementia, reducing their risk of suicide by 45%. These benefits only apply to high octane decaffeinated coffee drinkers. Some people consider coffee to be a healthy drink, but like most foods, drinking too much can cause side effects. For example, too much use of caffeine can cause headaches. This is mainly due to caffeine withdrawal. Because the blood vessels in the brain become accustomed to the effects of caffeine, stopping caffeine suddenly can cause headaches. Other symptoms of caffeine withdrawal include anxiety, irritability, and sleepiness. Sudden withdrawal can cause tremors in some people. Although very rare, caffeine overdose is also possible. Overdose symptoms include confusion, hallucinations, and vomiting. Overdose can lea...

Clathrus ruber is a type of mushroom belonging to the family Phallaceae and the type species of the genus Clathrus. It is commonly known as reticulate stinkhorn, basket stinkhorn, or red reticulate, and features round or oval, hollow, globular fruiting bodies with twining or reticulate branches. These fungi are saprophytic, feeding on decaying woody plant material and are often found singly or in groups in garden soil, lawns or garden chips. Although considered primarily a European species, S. ruber has been introduced to other areas and is now widespread on all continents except Antarctica. The species was described in scientific literature in the 16th century, but was not formally described until 1729. The fruiting bodies at first look like whitish "eggs" attached to the ground by strings called rhizomorphs. The eggs have a delicate, leathery outer shell surrounding a compressed web surrounding an olive green spore mucus layer called ...

Ants are toothless animals and have no teeth. However, their long tongues are large enough to swallow the 35,000 ants and termites they swallow daily. The giant ant, the largest of the four species of anteater, can measure up to 8 feet in length from the tip of the beak to the tip of the tail. It is covered in grey-brown fur, white forelegs, a black stripe running from chest to back and a bushy tail. Giant ants are found in South and Central America, but their numbers have declined significantly in Central and South America.   To thrive, you must be able to move across large areas of the forest. They are mostly found in tropical and dry forests, savannas and open grasslands, where they eat many ants. Giant ants use their long beaks, sticky saliva and efficient tongues to bore into ants with their sharp claws. However, they must eat quickly, moving their tongue up to 150 times per minute. Because ants face heavy stings, the ...

The Onagadori (roughly meaning "respected bird") is a rare breed of long-tailed chicken from Japan. It was initially thought to be a descendant of Shoukoku, but recent modern genetic studies have undermined this theory. Onagadori is recognized as a living national treasure of Japan and is so far unique in its country of origin. Onagadori are characterized by tail hair that does not fall out, and if kept in good condition, will grow well for as long as the rooster lives. Hens usually shed their hair like roosters, covering their head, chest, back and legs. Onagadori also have long, fluffy feathers, and the chick itself shows signs of being rich in plumage. To be considered a long-tailed grouse (Onagadori), a bird must have a tail of at least 2 m. Otherwise, it can be considered a phoenix chicken, a breed of onagadori. The Onagadori is 12-27 feet long, making it the king of all long-tailed chicken breeds. Onagadoris has a single comb, ...

A resolution of 576 million pixels means that 576 million pixels must fill an area the size of a field of view to produce a screen with an image so crisp and clear that individual pixels cannot be distinguished. To arrive at his number, Dr. Clark predicts optimal visual acuity across the entire visual field. That is, assuming the eyes are moving around the scene in front of them. However, if you look at the length of the image, the resolution drops to about 5-15 megapixels. This is because the eye has many imperfections that cannot be captured by the camera. You can only see high resolution in a very small area of ​​your field of view called the fovea. The blind spot is where the optic nerve meets the retina. We move our eyes around the scene not only to get more information, but also to correct these defects in our visual system. The eye must store the image in a memory bank, not in the camera lens. Like a detective, you gather clues from ...

When the Apollo astronauts walked on the surface of the Moon, they left a mark that would remain there for a very long time. In a previous study of lunar rocks collected by astronauts during the Apollo missions, researchers found that the rocks disintegrate at a rate of about 0.04 inches per million years. "From a human point of view, this may seem like an eternity, but from a geological point of view, there may be no traces of the Apollo probes for 10 to 100 million years," said Mark Robinson, a scientist of Arizona State University. The eventual disappearance of the human footprint on the Moon could encourage some form of protection for the places where the Apollo astronauts landed and explored. "Because the moon has no atmosphere, wind and water erosion doesn't dissipate as quickly as on Earth, so it has a more permanent characteristic."

Dubai may be the international playground of the world's superstars, but none of them can overshadow their biggest star, the Burj Khalifa. Located in the bustling heart of Dubai, the needle-shaped superscraper will take center stage on the iconic skyline, where millions of visitors and VIPs flock to the world's most famous address every year. The tallest man-made structure is the ultimate symbol of the city's glitz, glitz and excess. Raised 828 meters above the city, the 200-story Burj Khalifa project (capacity of 160 people) was launched in January 2010 by the ruler of Dubai, Sheikh Mohammed bin Rashid Al Maktoum. At its peak, more than 12,000 international workers were employed per day and a total of 22 million man hours were required over the six years it was completed. The Burj Khalifa is twice the height of the Empire State Building in New York and three times the height of the Eiffel Tower in Paris. It surp...

Momčilo Gavric (1 May 1906 – 28 April 1993) was the youngest known soldier of World War I, joining the army at the age of 7 and becoming a corporal at the age of 8. He was born in Trbusnica, on the slopes of Mount Guevo, near Loznica, the eighth of 11 children of Alimpie and Elena Havrich. In early August 1914, Austro-Hungarian soldiers of the 42nd Infantry Division of the Croatian Home Guard wounded and hanged his father, mother, grandmother, three sisters and four brothers. His house was also set on fire. Momchilo survived because he was not at home when the incident occurred. His father had previously sent him to his older brother. Familyless and homeless, Momčilo visited the 6th Artillery Division of the Serbian Army near Gučevo. After hearing what happened, Dimitrii Tukovic's brother, Major Stevan Tukovic, took Gavric to his unit and assigned a soldier from the unit, Milos Misovic, to be Gavric's guardian. That night, he retaliated by ...

Stockholm experimented with keeping rewards and punishing speeders. I entered a lottery where the prizes come out of the fines paid by speeders for driving over or under the speed limit. The so-called speed camera lottery is a great solution to change your behavior on the road. Kevin Richardson entered Volkswagen's The Fun Theory competition in 2010 with his speed camera lottery idea. The concept was so strong that Stockholm held a provisional exam a year later. When a car passes a certain intersection, a camera takes a photo and measures its speed. Drivers were fined if they exceeded the speed limit. However, this money was used to enrich a unique fund called the obedient drivers lottery. If you're not a speed freak, you can enter the lottery for a chance to win money from people who don't follow the rules of the road. Simple and perfect. Sticks and Carrots are on a whole new level. Punish free riders and reward behaviors that benefit so...
