They Removed This From NCERT — Here's Why

Описание: Did ancient India really discover key concepts of astronomy and mathematics centuries before Europe?
Or is this just another exaggerated claim floating around?

In this video, we break down the actual historical evidence using primary texts, peer-reviewed research, and verified academic sources to answer one question:

👉 Did India know astronomy before the West?

From Aryabhata’s model of Earth’s rotation (499 CE) to the Kerala School’s infinite series (around 1400 CE), and the global journey of the sine function, this video separates fact from myth.

No WhatsApp forwards.
No blind nationalism.
Only evidence-based history of science explained clearly.

🔍 What You’ll Learn in This Video
The truth about Aryabhata vs Copernicus
Did India really develop calculus before Newton
The origin of the sine function (jya to sine)
How zero, decimal system, and algorithms spread from India to the world
The real story of the Kerala School of Mathematics
What NCERT textbooks include and what they leave out
Honest comparison of where India was ahead and where the West led
⚠️ Important Note

This video is not about proving superiority.
It is about correcting the historical record using credible sources.

Some claims are strongly supported.
Some are debated.
And we clearly separate both.

🧠 Why This Matters

Modern science did not emerge from one place. It was built through global knowledge exchange.

Understanding this:

Makes you a better thinker
Helps you question simplified narratives
Gives you a deeper appreciation of science history
