How difficult is Zhou Wei’s three math problems in The Strongest Brain? Is it possible for ordinary people to calculate without any tools? What I want to explain in this article is that in fact, ordinary people can complete very complicated calculations with the help of recognized mathematical methods and their own efforts.
Even a small mistake that can be almost completely forgiven can trigger a catastrophe. Do not believe it? Take a look at these four famous examples.
As the most famous shipwreck vessel in history, the Titanic has many stories behind it. The evacuation process of “Women and Women’s Priority” in the event of a crash has touched countless people. However, the two economists have counted the discovery of shipwrecks in the past three centuries. The Titanic’s “women and women’s priority” is just a special case.
Mathematicians are not willing to be photographed as neuropathy. They also dare to show their sexy literary side. So, with this “Love and Math Ritual”, and see how the mathematics handsome Edward Frenkel of the University of California at Berkeley uses the formula. + Beauty pays tribute to Yukio Mishima.
A preprint of the papers from Zhejiang University and other units was promoted by the media as “the winning strategy of finding stone scissors.” If it’s just that simple, is it worth studying? Fortunately, this is a title party, the true meaning of this research, and several stories here will be interpreted for you.
Researchers at the University of Alberta in Canada have invented a method to determine how much urine is present by measuring the amount of an artificial sweetener, acesulfame, in a pool water sample. As a result, about 0.01% of the water in the pool is urine!
If you want to buy a car, you need to shake the number first. If you can’t shake it all your life? Li Xiaosong, deputy director of the Municipal Communications Commission, explained that “there is a chance to shake the number once a month. People who are not in the middle can always shake the number in the shaking pool. I believe it will definitely shake.” Unfortunately, this is the reason for shaking the pool. The number will accumulate and the probability of winning will be lower and lower. The dead rationality tells you that the average needs to be infinite for many years!
Before the 19th century, the Vienner code could be said to be the pinnacle of cryptography. Since Babbage and Cassis broke the security of cryptography, cryptography is in a state of confusion. The coders are always looking for new passwords. In the early 20th century, the Italian Marconi invented the radio technology, making the need for secure encryption more urgent.
In the structure movie “The Pirates of the Dream”, which has become a box office masterpiece, there have been two scenes of the “Penrose Stairs”. One time, at DiCaprio, he explained to Peggy, who later became a “dreamer”.

can! As long as he squats once a day and lasts for 32 years, he can give birth to thousands of children, such as the Sultan Ismail of Morocco. With this research, anthropologists at the University of Vienna in Austria won the 2015 Nobel Prize in Mathematics.
