Tetraphobia is afearof the number4. It is asuperstitionfound most often inEast Asian areas likeChina,Japan,Korea, andTaiwan.
An elevator in Shanghai – floor numbers 4, 13 and 14 are missing
The Chinese word for four (四, pinyin: sì, jyutping: sei), sounds very similar to the word for death (死, pinyin: sǐ, jyutping: sei).
Chinese people take care not use the number 4 during important holidays, or if someone in the family is sick. Numbers such as 14, 24, and so on, are not used because they also have the number 4 in them. Buildings sometimes do not have floors with these numbers, apartments and hotels do not have rooms with number 4, 14, 24 and so on. Table number 4, 14, 24, may be often left out in wedding dinners or other social activities in these countries. Where there are a lot of apartment buildings, buildings that should be 4, 14, 24, are called 3A, 13A, 23A, and so on.
In Hong Kong, some apartments such as Vision City and The Arch do not have the floors from 40 to 49. Immediately above 39/F is 50/F, leading many who do not know about tetraphobia to think that some floors are missing.
The Chinese start numbering their military aircraft with the number 5, such as the fighter plane "Shenyang J-5". The Taiwanese and the South Korean navies do not use the number 4 when giving flag numbers to their ships.
In cities where East Asian and Western cultures come together, like Hong Kong and Singapore, it is possible in some buildings that both 13 and 14 are left out as floor numbers, along with all the other 4s.
In Korea, tetraphobia is not as important, but the floor number 4 is almost always left out in hospitals. In other buildings, the fourth floor is sometimes named "F" (Four) instead of "4" in elevators. Apartment numbers with a lot of the number 4 (such as 404) are hard to sell, and often they are not worth as much money.
Sixgill sharks are among the oldest creatures on Earth, with ancestors dating back to over 250 million years, well before dinosaurs. Scientists at the Florida Institute of Technology have identified and confirmed the existence of a new shark species residing in the Atlantic Ocean. For confirmation, scientists used genetic testing and named the species “Atlantic sixgill shark.” The shark is different than its counterparts in the Indian and Pacific Oceans and measures up to 6 feet in length. “We showed that the sixgills in the Atlantic are actually very different from the ones in the Indian and Pacific Oceans on a molecular level, to the point where it is obvious that they’re a different species even though they look very similar to the naked eye,” said Toby Daly - Engel, Assistant Professor and shark biologist at the Florida Institute of Technology. Atlantic sixgill sharks are far smaller than their Indo-Pacific relatives, which can grow to 15 feet o...
For the first time astronomers have glimpsed a long-predicted population of black holes lurking at the heart of the Milky Way. Scientists already knew our galaxy’s core holds a supermassive black hole weighing millions of times more than our sun, and that this great beast is enveloped by a diverse entourage of lesser companions. Trapped in its gravitational clutches, run-of-the-mill stars whip around this gargantuan black hole like fireflies in a hurricane. So, too, do astrophysical exotica such as neutron stars and white dwarfs—the remnants left by normal stars when they die. Presumably black holes should be there as well, either born on the galactic center’s doorstep from the deaths of massive stars or arriving via migration from farther out. Such black holes should each weigh 10 to 20 times more than our sun. That bulk would make them behave a bit like heavy pebbles outpacing fine silt to the watery bottom of a well, jostling through the lighter surrounding stars to reach stab...
An illustration of ULA's Vulcan rocket launching toward space. (In this image, used-up rocket motors are falling back to Earth. SpaceX turned heads around the world on February 6 with the first-ever launch of Falcon Heavy. The 230-foot-tall rocket's three boosters helped push Elon Musk's Tesla Roadster into space, peeled off after running low on fuel, and then careened toward Earth. Two of the 16-story boosters rocketed to a safe landing (the third fell into the ocean), and the flight was hailed as a huge success. It proved SpaceX could lift twice as much payload to space for about 25% of the cost of its closest competitor while recycling rocket parts worth tens of millions of dollars. That primary rival is United Launch Alliance, a company that aerospace industry titans Boeing and Lockheed Martin formed in 2005. ULA's largest rocket, the Delta IV Heavy, costs $350 million per launch, according to company CEO Tory Bruno. Delta IV Heavy is far more expensive t...
