In the previous tweet That was all about the zinc from the ore in Ancient India.
Now let's talk about Rust free Iron pillars/beams which are approx 1000-2600 year old and even today rust free.
Its amazing and wonder in the field of metallurgy.
Iron gets easily oxidized
This pillar has 3 stanza six line Sanskrit brahmi Inscription which says this is Set up by chandra gupta vikaramaditya (375 AD - 414 AD)
This is 7 feet long and till now it is rust free Even delhi is the most populated area in India.
This is in Qutub complex now.
In Dhar,M.P. From 1000 AD
Here is a temple Lateshwara mandala specifically it is for Lord shiva
Lateshwara means Lord of pillars,
pillar is in the shape of Shivlinga with trishul mounted on top. Its total length was around 15 meter 2 time of delhi and still rust free.
Above Lateshwara temple was established by king Bhoj is largest non corrosive iron pillar in the world in 1000-1055 AD.
It is 15 M in height and 7 MT in weight in 3 parts.
History of lateshwara temple--
Dhar was conquered by Allaudin Khilji in 14th CE. After which Lateshwara Temple was converted into Lat Mosque. The pillar was erected infront of that mosque.. A small top portion was sent to Mandu & erected infront of the Jami mosque there.
In 1531 Bahadur Shah - Sultan of Gujarat attacked and wished to carry the Iron pillar from Dhar to Gujarat. However while digging out the pillar, it fell down & broke into pieces. So he abandoned his plan.
Later on Jahangir wished to carry it to Agrato plant it as a lamp post infront of the tomb of Akbar But somehow it never happened.piece which sent to Mandu, it has been identified by same with the iron pillar known as Khilji's spear which stands in the Jami mosque of Mandu.
Konark temple Iron beams are also in the same category which are still rust free till now from 1300 to till now.
India was once the master of metalurgy from iron,zinc to gold and the biggest gift of India to world is wootz steel known as wonder material of the orient.
The world famous Damascus swords were made of Wootz steel and these were considered to be the most prized possessions and gift items (certainly more precious than gold and silver) by the aristocracy.
There is no evidence to show that any of the nations of antiquity besides the Indians were acquainted with the art of making steel. The word Wootz is a distortion of the Kannada-Telugu word Ukku, for steel.

What is the #reservation in AIQ (All india quota) in state seats.
There are three different kinds of seats available in all Medical Colleges across the country. In the Government Medical Colleges of the country, there is a 15 percent All India Quota.
Suppose 100 seats are there in any state govt medical college,
15 seats will be reserved for AIQ
Now new reservation policy
From these 15 seats 15% will be for SC that means 2 or 3, 7.5% for ST that means 1 or 2, 27% for obc that means 4 seats and 10% for EWS mean 1 or 2
Here 7 seats from AIQ will be available for all.
Now remaining 85 seats there was already reservation applied in Admission since Last time when admission in reservation was brought.
Also in AIQ reservation for SC and ST was already applied.
The Ancient India and its amazing technology of metallurgy.
Zinc is the most difficult to smelt since zinc volatalises at about the same temperature of around 1000°C to smelt zinc ore. As a result it would form as a vapour in the furnace which would immediately get reoxidise.
However in India there is unique evidence for the extensive and semi-industrial production of metallic zinc at the Zawar area of Rajasthan. The mines of Rajasthan have given definite evidence of zinc production going back to 6th Century BC.
Just think about it.
An ingenious method was devised of downward distillation of the zn vapour formed after smelting zn ore using specifically designed retorts with condensers and furnaces, so that the smelted zinc vapour could be drastically cooled down to get a melt that could solidify to zn metal.
@Javedakhtarjadu are you seeing this?
This is now a "Khandahar" but it was the first destruction done by any ijlamic man in India actually it was a temple which Mohammad bin Qasim converted into a mosque by destroying it.
This is the difference between obama and shahjahan.
He destroyed many temples in sindh and then he returned after defeating king Dahir who gave Asylum To Persecuted Grandson Of Pro phet Moh ammed.
You talk about dharma and it was the first incident in India when someone captured the daughters of any king. Source - chachnama

80 वर्ष की आयु के क्षत्रिय राजा छत्रसाल जब मु लमानों से घिर गए और बाकी क्षत्रिय राजाओं से कोई उम्मीद ना थी तो उम्मीद का एक मात्र सूर्य था बाजीराव बल्लाळ भट्ट पेशवा ।
छत्रसाल ने बाजीराव को खत लिखा
जो गति ग्राह गजेंद्र की सो गति भई है आज
बाजी जात बुन्देल की बाजी राखो लाज ।।
अर्थात: जिस प्रकार गजेंद्र हाथी मगरमच्छ के जबड़ो में फंस गया था ठीक वही स्थिति मेरी है आज बुन्देल हार रहा है बाजी हमारी लाज रखो ये खत पढ़ते ही बाजीराव खाना छोड़कर उठे उनकी पत्नी ने कहा खाना तो खा लीजिए तब बाजीराव ने कहा 👇
आज एक क्षत्रिय ने एक ब्राह्मण से मदद मांगी है और ऐसे में यदि मैं खाना खाता रह गया तो इतिहास कहेगा कि उसने भोजन को महत्व दिया।
बाजीराव बिजली गति से मात्र 500 घोड़ों के साथ पहुंच गये और मात्र 48 घंटे में फंगस खां की गढदन को विच्छिन्न कर छत्रसाल को विजय दिलायी।
Who gave world wings?
Your answer will be Two American brothers in 1903 just for 12 seconds in their first attempt.
You may be right but when you will read about "Shivkar Bapu ji Talpade" you will be disappointed as its wrong answer as its Shivkar Bapu ji who did this in 1895.
He took birth in Mumbai in 1864 and he was great scholar of sanskrit and vedic granthas,
He took insoiration from the famous book of "Bharadwaj Muni", "Vaimanika" and designed a "Viman" with the help of bamboos he used liquid Mercury as fuel.
Although we were under british rule that time so fund related issue was there but anyway he managed it and after designing it he gave it name as "Marutsakha"
Marut is hindi synonym of air and sakha means friend
So its meaning was "friend of air".
