🧵 Thread: Did Ancient India Know Pi (π) to 31 Digits?

Yes – they hid it in a Sanskrit shloka!
No calculators. No computers.
Just brilliance, devotion, and mathematics.
Let’s decode the mind-blowing secret of the Katapayadi system 👇

1. This is the shloka:
"गोपी भाग्य मधुव्रात..."
It looks like a devotional verse to Krishna/Shiva.
But hidden inside... is the value of Pi up to 31 digits!
Let’s see how 👇

2. The system used is called:
Katapayadi Samkhya (कटा पयादि संख्या)
Developed in ancient India - this system assigns numbers to Sanskrit consonants.

It let sages encode large numbers into verses. Genius & poetic!

3. Here's how the Katapayadi system works:

ConsonantValue

क ख ग घ ङ1 2 3 4 5
च छ ज झ ञ6 7 8 9 0
ट ठ ड ढ ण1 2 3 4 5
त थ द ध न6 7 8 9 0
प फ ब भ म1 2 3 4 5
य र ल व2 3 4 5
श ष स ह6 7 8 9

Vowels? They're ignored.
Only consonants matter numerically.

4. Now take the shloka:
"गोपी भाग्य मधुव्रात श्रुंगिशो धधिसंधिगा..."
Apply the Katapayadi system… and you get:

Pi = 3.1415926535897932384626433832792
🧠 That’s 31 digits of π - centuries before Europe!

5. Think about this:
• Encoded math in poetry
• Devotional + Scientific
• Memorized by millions
This was not just math - it was civilizational genius.

6. This is how India taught science:
• Through shlokas
• Through memory
• Through beauty
No textbooks. No whiteboards.
Just vibration, language & truth.
Sanatan Wisdom = Timeless Science

7. Westerners discovered π's accurate digits much later:
• 15th century: al-Kashi
• 17th century: Ludolph van Ceulen
• But India?
Already had 31 digits - in a prayer.

8. This wasn't the only case:
• Astronomy
• Algebra
• Trigonometry
All encoded using metres, rhythm, and shlokas.
It made learning divine.
Mathematics = Mantra.

9. Imagine if today's kids learned math this way.
Not boring formulas, but divine verses.
Not fear - but fascination.

We must reclaim this lost art of wisdom.

📌 This isn’t mythology.
It’s mathematics.
It’s memory.
It’s Made in Bharat 🇮🇳
Let’s not just be proud of it - let’s bring it back.
