  1. From where you got the 99% fact? It is though right that humans have same genetic composition and hence fairly similar and not identical DNA structure.
  2. I came across a formula derived by Ankur Tiwari, which he says enables division by zero. The website claims This formula enables us to divide in a unique way without using denominator. This formula is based on the principle that, If the value of X divided by Y (X/Y) is A than by using this formula we can find out A without dividing X by Y directly, that means without dividing X by Y we can find out its value. This is the reason why ‘Bhartiya New Rule for Fraction’ is capable of diving by Zero. The interesting points in regard of this formula are :- 1.‘Bhartiya New Rule for Fraction’ is based on present phenomenon and rules of mathematics. 2. It is very simple and easy formula. 3.Greatest benefit of ‘Bhartiya New Rule for Fraction’ is that it is capable of dividing by Zero and giving its value as an integer. 4.‘Bhartiya New Rule for Fraction’ can be used to find out the value of four not defined trigonometric ratios tan90, cosec0, sec90, cot0. So that these values can be utilized in the field of astronomy and other fields related to mathematics. 5.If in place of simple division (X/Y), ‘Bhartiya New Rule for Fraction’ is used in any digital electronic device as its processing command for division in processor, it will results in permanently elimination of ‘divide by Zero’ error from that device. How would it affect mathematics? Is there a fallacy in there? Let us discuss...
  3. This is not always the case. Porn producers know that females too watch porn. You are just narrowing the largest earning industry.
  4. The second question itself is a hint to the first one.
  5. But you would have to present it to all the powerful and dictator like people who are experts here and bow before them.
  6. I was asking about the text in bold in the quote box-<br class="Apple-interchange-newline">
  7. Who here challenges swansont's rep point record?

      What's the record?

      1952 points

    3. Moontanman


      seems low to me too

  8. Where you got that from?
  9. Yes, everyone would be derailing the discussion and abusing those who gave negative. But, it can be highly insightful for some to know who agree with them and who not.
  10. I am not looking for reference books currently but full text books type. But, Thanks!
  11. I know about an old philosopher who wrote about 'how to live' and all, wrote that females have sexual desires 8 times that of males!

    Dig your contents people and get us the classics.
  16. Lot of workload today! Tomorrow is the Science exam!

  17. unless you are not debating!

    You could make a new post saying 'thank you' and keeping the original post intact.

    SFN Classics

    Let us have a collection of SFN classic threads from all the sub-forums. It would nice if you name the link you provide with the topic name itself.
  20. Yes, it is based on Uttarayana and Dakshinayana.
  21. Vastor, for standard deviation, as I understand, you have to take any larger mean and subtract all other from it. EDIT: For example, say you take a larger mean x, then the standard deviation for the first frequency would be x-(mean of the frequency)
  22. Sri Caitanya Mahaprabhu's original teachings have always proved devotion to be the ultimate path. And even those who debated about the shastras were not liked by him.
