Bakshali Manuscript on mathematics is older than many Greek writers. It is also a precursor to Aryabhatta's contribution

4/16
Bakshali Manuscript written on birchbark was found at Bakhshali near Mardan on the north-west frontier of India in 1881
Folio 50, mention that it was scribed by a Brahmana, a prince of calculators, the son of Chajaka (चाजाका) a hindu and a great devout to #Shiva

Given that the Script is a copy of an original. The original work must date prior to 2nd Century.
This survived written copy may be reprint of older work carried over long before.
The researcher agreed that Script was totally Indigenous

6/16
The Manuscript elaborates:
linear equations
Indeterminate equations of the 2nd °
Arithmetical progressions
Quadratic equations
Approximate value of √
Complex series
Problems of the type x (1-a1)(1-a2)....(1-an) = P
The computation of the fineness of gold
Mensuration

7/16
The numerals used in the Bakhshali manuscript resembles to Kannada numerals

8/16
The scheme of exposition used is Sutram सूत्रम Udaharanam उदाहरनम् Styapanam स्त्यपनम Nyasa न्यासा Karanam कारणम Pratyanam परत्यनाम
QED what i learnt in my schooling 🙂

Negative Sign was denoted as "+" Plus sign while Positive Sign as "."

10/16
Certain operators are often abbreviated such asfor bhaga, placed after a term to indicate that it is itd ivisor.
se°3 for sesam, a remainder.
mu°5 for mulam, a root, a quantity that has a root, capital,
pha°7 for "phalam", an answer

11/16
The rule for approximation and 2nd Approximation of Square root is given in the form of an equation.

12/16
The writers asserts that Indian mathematics has reached Nessel-mann's third and the last stage of development of the science of algebra long before all the other nations of the world by inventing good system of notations

13/16
Change ratios, Time Measures, Arc Measures, Money Measures, Weight Measures, Length Measures, Capacity Measures are well defined in the manuscript

1️⃣ Every art history course starts in Greece.

But here's what they don't mention: almost every Greek painting from the Classical period is gone. Lost.

Meanwhile, in India, 700 years of continuous wall paintings still exist.

Let's talk about what survives vs what we worship. Image
2️⃣ Ajanta Caves.

Painting phases dated 2nd century BCE – 5th century CE.

That means: Ajanta begins before Alexander. And continues after Rome adopts Christianity.

This isn't parallel art. This is a continuous painting tradition spanning 700 years. Image
3️⃣ Where are Greek paintings from 480–323 BCE?

Answer from classical scholarship: almost entirely lost.

What survives:
• Roman wall paintings (1st c. BCE–1st c. CE)
• Literary praise by Pliny the Elder
• Copies, not originals

An origin remembered by texts vs one preserved in pigment.Image

1️⃣ The first diamond ever touched by human hands came from Indian soil. Golconda mines, 4th century BCE. We didn't dig for profit. We picked them from riverbeds like pebbles. 💎

Then someone realized they could own what the earth gave freely. Image
2️⃣ 1600s: Golconda diamonds weighed 23 million carats annually. The world's entire supply. Tavernier documented it. Shah Jahan embedded them in the Peacock Throne.

We controlled brilliance itself. Image
3️⃣ 1739: Nadir Shah walks into Delhi. Walks out with the Kohinoor and the Peacock Throne. Combined worth? Impossible to calculate. The throne alone held 26,733 gems.

First lesson: What glitters gets taken. Image

1/ ASI admits stone jars occur across Assam, Laos, Vietnam, and the Philippines.

That admission changes everything. Once you acknowledge geographic spread, local narratives collapse. Interpretation must go regional. 🧵 Image
@himantabiswa @ASIGoI @MinOfCultureGoI @tourismgoi @gssjodhpur @UNESCO 2/ ASI records no present-day tribe claims authorship.

That's not ambiguity. That's normal. Mortuary traditions outlast populations, languages, identities by millennia.

Continuity ≠ authorship. Image
3/ ASI calls them ancestral bone repositories — already placing them in secondary burial systems.

The same function archaeologically proven at the Plain of Jars.

Function aligns across regions. Not coincidence. Image

Meet Bhagirathi — the river that dragged Ganga from Shiva's hair to earth.

Rigveda calls her "the one who flows with the speed of thought."

Today? A trickle dying before Gangotri even starts.

From cosmic torrent to seasonal sewer. Thread 🧵 Image

Bhagirathi begins at Gaumukh — "cow's mouth" glacier.

1935: 300-meter ice wall, roaring.
2025: Snout retreated 3+ km uphill. Glacier lost 25% volume since the 1960s.

Your Himalayan trek selfie is on her corpse. 📸❄️ Image

Vedic seers saw her as divine:
नदीं न संनादतीं दमूनसम् (RV 10.75.4)
"The river that roars like a bull in rut."

Now? Summer discharge down 40% since 1990.
Sometimes she doesn't reach Devprayag to become "Ganga."

Literal identity crisis. 🏔️💧 Image

You already know that for over 2,000 years, Indian smiths forged steel so sharp it cut European swords in half. So resilient it became legend across continents.

By 1900, those same smiths were classified as backward. Primitive. Incapable of innovation.

What happened between? 🧠⚔️ You don't know!!

A 5-step manual for erasure. READ On 👇

#decolonisation #UncropTheTruth

Step 1: Extract the technique

Indian wootz steel arrived in British laboratories in 1795. Samples were analysed, chemical compositions documented, papers published in the Royal Society. The steel was credited to "Eastern origin." The smiths who forged it? Unnamed. Untraced. Irrelevant.

The technique was extracted. The technician was erased.

2/7Image
Step 2: Disrupt the ecosystem

Wootz steel required specific forests for charcoal, particular ores, seasonal smelting cycles. Colonial forest laws between 1855–1878 criminalized wood collection, turned smelting zones into "reserved land," cut access to raw materials.

The furnaces went cold. Not because knowledge disappeared, but because resources were locked behind permits the smiths couldn't obtain.

Theft, loss, and inventory failure

1/
When artefacts disappear from protected monuments, the response is usually administrative.
Files are opened, reports are written, and records are updated.
By the time this happens, the loss has already occurred much earlier. Image
2/
Many antiquities under protection are still incompletely catalogued, irregularly verified, or stored without consistent physical security.
In such cases, legal custody exists on paper, but effective control on the ground is weak or absent. Image
3/
Once local community presence was removed from many sites, informal and continuous surveillance disappeared with it.
As a result, losses are often discovered only years later, during audits or inspections, when recovery is no longer realistic.
