For the fastest puzzle fans, the traditional three-layered, six-sided Rubik’s Cube is not enough — they can solve it in 20 seconds. But when the newest hollow 12-sided puzzle was introduced to Taiwan recently, players spent 18 minutes to solve it.
It is almost 40 years since the first puzzle cube was invented, and the one everyone knows is the three-layered Rubik’s Cube successfully marketed by the Hungarian professor of architecture Erno Rubik in 1977. However, the world’s first such puzzle was a magic pyramid invented in 1970 by the German scientist Uwe Meffert. It hit markets in 1978, selling more than 90 million units that year. To date, more than 160 million have been sold.
Meffert recently brought his latest invention, the hollow 12-sided puzzle, to Taiwan. This innovative hollow puzzle makes it possible to see straight through the puzzle, and by increasing the number of sides from six to 12, the difficulty is increased further.
Kuo Chun-yi, a magic puzzle wizard who is an assistant professor in the mathematics department at National Taiwan Normal University, says the increase from six to 12 sides increases the variations so that more time is required to solve the puzzle, while the hollow design deprives the user of the possibility to use the colors as a criterion for judging progress, which means that the slightest lapse in concentration leads to confusion as soon as the puzzle is turned.
Two magic puzzle wizards who took the new invention for a spin at the event required 18 minutes to solve it. Kuo, who has been playing with magic puzzles for 10 years says that normal people might not even solve it in an hour or two. He said that if he played around with it a few more times, he might be able to get down to between five and 10 minutes, so considering that he solves the standard six-sided magic cube in 20 seconds, it is easy to see that the 12-sided puzzle is quite complicated.
There were also egg-shaped puzzles at the event, whetting the curiosity of visitors. Kuo, who has more than 70 magic puzzles in pyramid and other shapes said the egg-shaped design made it even more likely that the user would confuse directions, but because it is built on the traditional three-layered, six-sided principle, he could probably solve it in just two minutes.

Forget your pepperoni or other pizza toppings: Pizza Hut Taiwan has teamed up with Menya Musashi, a popular Japanese ramen restaurant chain, to serve up the world’s first ramen pizza, and it has attracted global interest after a CNN report about the new mashup was published on the front-page of its Japanese version. The new pizza has the toppings of a Japanese-style barbecue pork ramen — complete with thick noodles, barbecue pork slices, fresh chilies and white sesame, as well as a half-boiled egg sitting in the middle. It is also garnished with green onions and bamboo shoots on the side. Pizza
Taiwan’s Centers for Disease Control (CDC) last week confirmed the first domestic cases of a zoonotic vector-borne emerging infectious disease called the Tembusu virus in northern and central areas of the country. Detection of the virus within the nation’s borders follows previously confirmed cases in Malaysia, China and Thailand, making Taiwan the fourth country in the world with cases of the disease. The Tembusu virus was first discovered within duck farms in eastern China in 2010. According to Animal Health Research Institute Director-General Chiou Chwei-jang, in November last year the institute began to investigate a duck farm which was experiencing reduced
Russia-based face-changing application “FaceApp” took social media by storm last summer, as people used its filter to find out how they’d look like when they get old. Now, the app is back again with a gender-swapping function that transforms photos of faces into a different gender, and the filter has gone viral. FaceApp may be a fun tool, but such facial recognition apps raise security concerns, and they could pose a threat to your privacy. Late last year, the FBI even issued a warning about the app, which enjoys access to millions of photos, calling FaceApp and some other apps developed
Last Wednesday, Tesla Inc. displaced Toyota Motor Corp. as the world’s most valuable automaker, underscoring investor enthusiasm for a company trying to transform an industry that has relied on internal combustion engines for more than 130 years. Tesla Inc.’s market value also surpassed Exxon Mobil Corp.’s last Tuesday in a sign that investors are increasingly betting on a global energy transition away from fossil fuels. Exxon is the world’s second biggest energy company after Saudi state-controlled oil giant Aramco went public late last year. Shares of Tesla, which have more than doubled since the start of the year, climbed as much as 3.5
