  1. 1) The most basic works:

    + - X /

    counting, 1, 2,3 4...10, 100, 1000......

    units, such as inch, feet, meter,  hours, day, month.

    So we have to say people in Middle East and India did most of it.

    2) I do not think Chinese did any, because Chinese "invented" writing very late.

    -Middle Easterners invented writing 5000 years ago.

    -Europeans invented  a full set of writing  symbols  7000 years ago -- Vinča Script.

    -Chinese invented writing  3500 years ago.

    Chinese copied another's writing symbols.

  2. 1) Russians are Nothing to do with Europe.

    Russia is the North.

    India is the South.

    China is the East.

    US and UK are the West.

    UAE and Saudi  are the Middle.

    2) How the Big Mouth West to fight with Japan.

  3. 1) Russian proposed the element table. It is the greatest work in chemistry. Russians are Nothing to do with Europe.

    Russia is the North.

    India is the South.

    China is the East.

    US and UK are the West.

    UAE and Saudi  are the Middle.

    2) It is fun to see how the Big Mouth West to fight with the East.

    ..you must be smart.. ;)

    Programmers solve problems such as these every day..

    Check how Flight Radar works: https://www.flightradar24.com

    It does the same thing, but for all aircraft.

    If you know the aircraft's unique identifier, you can even use Flight Radar data.

    How to get a unique aircraft identifier? Find out from social media what a person is doing, where is in a few days, weeks, and analyze Flight Radar history..

     

    Thanks for your reply.

    If you really need it badly, you can install VirtualBox, download an older Windows ISO image file and install it on the virtual machine. Older Windows has older web browser e.g. Win7 has some IE.

    Thanks for reply, in fact I just want to make sure ActiveX is NOT exist in my system, it is no good for computer security.

    The BBC is one of the most trustworthy news sources around.

    (That news item is from February, by the way.)

    You said that "The BBC is one of the most trustworthy news sources around."

    The BBC had a program about the relation between Russia and China.

    It says China dominated Russia at the time of the Manchuria Empire.

    The BBC makes itself a joke.

    China was conquered by Mongols and Manchus, China dominated nobody.

    1)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..."
    Ref: “The Mongol Conquest Of China And Its Consequences”, by George Tait Edwards.

    ---Before the Mongol invasion, Chinese dynasties reportedly had approximately 120 million inhabitants; after the conquest had been completed in 1279, the 1300 census reported roughly 60 million people.
    Destruction under the Mongol Empire, Wikipedia


    --The figure put on the Mongolian invasions of northern China from 1210 to 1219 and from 1311 to 1340 are both of the order of 35 million.

    Mass killings | Guinness World Records


    --Bayan, the Mongolian Prime Minister suggested killing all Chinese with one of the most popular surnames.
    Bayan of the Merkid, Wikipedia


    -- “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).”
    Genghis Khan’s Yassa.


    2)After Mongols conquered China,  China became a part of Mongol Empire,  the Chinese King was ordered to commit suicide.
    Emperor Gong of Song, Wikipedia


    3)” Earlier historians had emphasized the power of Chinese to “sinicize” their conquerors… (But) the Grand Council operated only in Manchu until the 1730s, and many other important edicts and memorials did not have Chinese translations."
    New Qing History, Wikipedia


    ---Manchurian King,  Yongzheng said that,   “Heaven (The God) detested that the inner lands (China) had no one with virtue and so in concern ordered we outlanders to be lords of the inlands., then it is the people of the Middle Kingdom (China) who are no better than birds and beasts.”
    Ref: “Resolving Confusion with a Discourse on Righteousness”, by Manchurian King,  Yongzheng.

    4) Manchus  ruled China till 1911.

    In 1911, China became an independent country. (the last photo)

  7. 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.

    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.

    You have posted this in Applied Mathematics, and it is true that most if not all applications can be handled in other ways.

    Perhaps you do not know the role played by complex numbers in Pure Mathematics.

    Perhaps the simplest answer is that number systems were developed in sequence starting with the simplest counting numbers,

    Going through systems including

    The full set of integers.

    The ratioanl numbers (fractions)

    The real numbers

    The imaginary numbers

    The complex numbers (do you know the difference between imaginary numbers and complex numbers ?  What does complex mean ?

     

    Now each of these systems was introduced when it bcame apparent that there were equations in the simpler system, that had no solutions in the simpler system.

     

    For instance the equation 2x = -30 has no solution in the counting numbers or the positive integers, the equation 2x = 1 has no solution in the integers, the equation 2x2-20x+1=0 has no real solutions  - both solutions are complex.

     

    So complex numbers are necessary to provide solutions to all quadratic equatuions.

    Some equations of higher order do not even have a solurion formula withoug involving complex numbers.

     

    It is just fortunate happenstance that having developed complex numbers they find many useful applications elsewhere.

     

    Of course the process has not stopped there, there are even more complicated 'number' than complex ones.

     

     

    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.
