  • Wonder if that was a detriment rather than an achievement. Or possibly both?

    We can represent all these using a common notation. Imagine if you had to
    learn hundreds of names for each denominator, and after that, you don't
    have them all! Calculation becomes very difficult with specific names like

  • See - All people will not use all fractions.
    Gold smiths a few, Doctors and chemists a few. Metallurgist a few.
    We use the word - immi kooda kurayakkoodathu.
    Sidda medicines - anu alavu padarasam etc.
    Hence - specific numbers for specific people.
  • May be not...our tradition was 'sruthi, smrithi'....sound and relating a
    sound to a concept makes it easy to remember and relate.
    Our older generation used to multiply big numbers mentally, but our
    generation depends on calculator.

    I used to think I am smart, when i didnt read tables for my exams during
    schools and calculate it during exams. But today if I want to know what is
    16X15, I look for a calculator.

    So having a specific name for things makes it easy to remember and relate.

    How will you denote this in current system and make other understand what
    you are talking about??? 1/2323824530227200000000

    For our ancestors, it was simple..just one word. தேர்த்துகள் and both
    parties will know what they are talking about, without even writing it

    Vedas were never written down, till the europeans came in.
    Ganabadigal....would be able to recite the entire veda upside
    down..literally..but today..today while reciting any sloka if I forget one
    syllable, without the book I will not be able to proceed.

    my two pence...

    Used to remember an incident...when i was in the US. while in a queue at an
    eatery, an elderly person was before me and i think he had a bill of
    $10.61. He gave a 10$ and 1$ note and while the young lady was searching
    for change based on what her computer told her to give, this gentleman,
    wanting to help her, gave her 11cents, so that she can easily pick up 50c
    and return to him, instead of 39c.
    The lady got totally confused and did not know what to do. It delayed the
    process further and the old man was laughing like anything.
  • We have lost all thousand year knowledge of weights and measures in one
    generation. Sombu, marakkal, palam and many more measures commonly used
    by vegetable vendors, grocery shops and oil mandis are all gone from use
    and from records. How the 'illiterate' (by our standards) traders did
    complex sums - mukkal moonu vesam and araiya araikal - and non decimal
    I too had a similar experience. The cashier in a japanese business hotel
    did the calculations with an electronic calculator, and immediately
    cross checked it with abacus.
  • Dont worry - That is why we have abolished lower denomination coins.
    Now only 25P, 50 P and 1 Re. Soon it will be only Re1.
  • Hello Sir, It is mind boggling, indeed. Does anyone know where this was taken from? Were there any reference in any our litrature? -thanks
  • No sir, it was "forwarded" to me by friends and I shared it for our "learned" friends.
    I am a small fish in anocean of sharks !
