After WWII, the West did 6 things. 1) If you talk about the real GDP - the buying power, China is No 1, India will be No 2, the USA will be No. 3. 2) If you talk about the real GDP - the buying power, the top 5 will be China, India, the USA, Japan/Indonesia. There will be 0 European country. 3) England will be a second country. 4) The rest of the world consider Australia as Nothing. --The Malaysian PM Dr Mahathir said "Australia is a small country, and should act as a small country." --Australia has been described as “gum stuck to the bottom of China’s shoe.” https://www.theguardian.com/world/2020/apr/28/australia-called-gum-stuck-to-chinas-shoe-by-state-media-in-coronavirus-investigation-stoush 5) Even Australian consider the Chinese President is the most power man in the world. https://www.skynews.com.au/world-news/china/xi-jinping-is-the-most-powerful-man-in-the-world/video/c673dfb1075ffd1a1aca86acb2b0410e 6) The West believe the rest of the world would support them to fight with Russia, they just find out now the world do not care about the West.

Do we really need complex numbers?
PeterBushMan replied to PeterBushMan's topic in Applied Mathematics
The complex numbers (do you know the difference between imaginary numbers and complex numbers ? What does complex mean ? ---- imaginary numbers are in the form Yi. ---- complex numbers have two parts X+Yi, X is a real number. I only can understand complex number in that way - First we invented imaginary number which is not exist. then we try to find some uses of it. -
There is an axis for Imaginary numbers, and there is an axis for real numbers. So we can just use the X and Y axes, what is the difference? They can do the same thing.

How to remove ID/Password from windows 10
PeterBushMan replied to PeterBushMan's topic in Computer Science
Thanks! Anyway I am still using firefox. Another question is window 10 also keep your search records in search bar, and you have to delete them one by one, not delete all of them by one click. I am not surprise that The West is falling, it is just so dumb, example every website ask you do you accept "cookies" or not? lol, the rule must be made by those politicians know nothing about IT And those dumb webmasters use three frames, and give you 2 inches space to view their web pages.- 7 replies

Why China, Vietnam, North Korea support Russia? China, Vietnam, North Korea all called Russia as big brother. Mao called Satin as big boss. Chinese Called Stain as Kind father, "cifu". Chinese President Dr Sun Yat-sen said "Russia is our teacher." The West laughs at Russia lost a war to Japan, which Japan lost more soldiers. The West must forget the battle of Singapore, and the battle of Indonesia.

have a look at the short paper attached. The number of the equal triangles should be 1+n/(n/2), if n=10, it is 55. Of you also count those up side down equal triangles, it should be n^2, if n = 10, it is 100. Then what is the author talking about?

Do they have common sense? 1) Mongolia conquered China. Mongols killed 50% of the Chinese population. "...According to the Chinese history not more than one hundredth part of the population survived, the countryside was covered with human bones, the cities left desolate..." —“The Mongol Conquest Of China And Its Consequences”, by George Tait Edwards. 2)Mongols divided people into four classes, Chinese were the lowest. 1. Mongols 2. Semu people 3. Northern Chinese 4. Southern Chinese ---Society Under Mongol Rule, www.encyclopedia.com 3) Bayan, the Mongolian Grand Chancellor suggested killing all Chinese with one of the most popular surnames. Bayan of the Merkid, Wikipedia 4) Genghis Khan’s Yassa. “In cases of murder, one could ransom himself by paying fines which were: for a Mohammedan - 40 golden coins; and for a Chinese - one donkey (which was the cheapest).” 5) Marco Polo recorded that he met the Mongolian King, Kublai Khan, in Beijing. When Mongols took Beijing, Mongols killed almost the entire population of Beijing, and used the dead bodies to cook human oil. 6) After Mongols conquered China, China became a part of Mongol Empire. The Chinese King was ordered to commit suicide. Emperor Gong of Song, Wikipedia 7) Marco Polo recorded that Mongols called China as Manzi(barbarians). As European and Arab travelers started reaching the Mongol Empire, …. Southern China, ruled by the Song dynasty (By the Chnese King), was (called) Mangi, Manzi, Chin, or Sin. The word Manzi or Mangi is a derogatory term in Chinese meaning "barbarians of the south" but it was adopted by the Mongols to describe the people and country of Southern China. The name for South China commonly used on Western medieval maps was Mangi, a term still used in maps in the 16th century. Cathay, Wikipedia 9) At the tome of Marco Polo, China was a part of Mongol Empire. Please have a look at the map.

Can you create a crypto base on only SQL?

Please give me a simple proof, X^0=1. Thanks.

I still do NOT think so. 1) 0/0 =0, it is like 1/1=1, there is no such thing, "if we set 0/0= b then 0= bX0 for any b.". 0/0 only has one value, which is 0. 1/1 has only one value, which is 1. 2) It is easy to prove that X/0, X!=0 is NOT defined. since if X/0 = Y, then 0 X Y = X, and X!=0 are NOT possible.

0/0 = 0, means 0 X 0 = 0. It is well defined.
