#VirtualReality😎

#மெய்நிகர் உண்மை / மெய் மாயை

ஒரு பொருள் அல்லது இடம் அல்லது செயல் உண்மையாக நம் கண் முன்னே இருப்பது போல நம் மூளையை நம்ப வைப்பது தான் Virtual Reality.

#VR/AR/MR பற்றிய ஒரு எளிய அறிமுகம்🧵

[Prem SN Piramanayagam @PremNTU]

Recently, we published our work in Nature Communications.

In this paper, we demonstrate "switching of magnetization using orbital torque", without using an external magnetic field. Perhaps, this is the first demonstration of such a switching.

Ruthenium was used as the orbital Hall layer. Field-free switching was achieved due to a design that involves spin-reorientation of magnetization in a system with synthetic antiferromagnetic coupling.

Thanks to my students, group members, and collaborators who made this work possible.

Super excited for this event about blackholes . Really happy to have @natarajanphys for our Motta madi event. The event is on July 19 at Pagir , Thiruvanmiyur.

Post the event , we will also observe and few bright stars through our 12 inch telescope. Dm @starvoirs for booking.

Great progress towards right future🖤❤️.

Including AVGC-XR right from school curriculum and IP based collateral are very important moves.

Suggesting @ptrmadurai to add #DigitalTwin under XR and later branch out. It is a double digit CAGR industry.

[Dr P Thiaga Rajan (PTR) @ptrmadurai]

I am pleased to share that on 13/03/2026, our Hon’ble Chief Minister Thiru @mkstalin launched the Tamil Nadu AVGC-XR Policy 2026.

This marks an important step in Tamil Nadu’s journey toward a USD 1 trillion economy, where our technology policy increasingly prioritises depth, quality, and long-term value creation rather than scale alone.

The Animation, Visual Effects, Gaming, Comics, and Extended Reality (AVGC-XR) sector sits at the intersection of creativity and frontier technologies such as AI and advanced computing, with applications across education, healthcare, industrial design, tourism, and advanced manufacturing. Our objective is for Tamil Nadu to capture 20% of India’s AVGC-XR market and create 2 lakh high-skill jobs by 2030.

A key focus of the policy is regional diversification. While Chennai will serve as the primary hub, the ELCOT Viyan AVGC-XR Centre of Excellence will anchor a spoke-and-hub ecosystem extending to Madurai, Coimbatore, Trichy, Salem, and Tirunelveli, ensuring opportunity across the State, alongside focused skill development and support for original IP creation.

The policy is the result of two years of close collaboration with industry and ecosystem partners, reflecting a shared vision to build a globally competitive creative economy from Tamil Nadu. We are confident that this ecosystem will generate high-quality jobs, globally competitive creative output, and sustained economic momentum for the State.

All the mobile phones are mandated to manufacture with NavIC from 2025.
Backward integration done successfully but the infrastructure part should have focused more. We had multiple failures in atomic clock(all imported) from day one.
Hope ISRO will launch backup satellites soon.

[Satheesh Kumar @saysatheesh]

Very sad news 😌😌

IRNSS-1F செயற்கைக்கோளில் இருந்த Atomic Clock நேற்று முதல் செயல்படல.

இது வரை நாம Navigation 11 sattellite அனுப்பி இருக்கோம்.. அதில் ஏற்கனவே 7 செயல்படல. மிச்சம் இருந்த 4 இல் இப்போ 3 தான் செயல்படுது.

Navigation system வேணும்னா குறைந்தது 4 satellite செயல்படனும்

இந்தியாவுக்கு என Navigation system இந்த நிமிஷம் செயல்படல.

இனி மாற்று ஏற்பாடு செய்யும் வரை மற்ற நாடுகளை தான் சார்ந்து இருக்கணும்.

முன்னொரு காலத்தில் satellite ல பெரும் சாதனைகள் செய்த நம்ம நாடு proactive ஆ சிந்திக்காம சில முக்கியமான விஷயங்களில் கோட்டை விட்டுட்டோமா என தெரியல

ISRO அடுத்து என்ன செய்ய போகிறது என பார்ப்போம்

Modi gov't has 'temporarily suspended' the forced feeding of Fortified Rice to 80 cr poor Indians.

Context:
In May 2023 my @reporters_co colleague @shreegireesh unearthed the scam called Modi govt's Fortified Rice Scheme.

Based on spurious science and failed pilot projects, against warnings by its own experts, Modi gov't had pressed ahead to force feed fortified rice to all of 80 crore poor in India. The orders to do so had come from the top.

There were foreign business interests backing the scheme. They stood to earn thousands of crores annually from this move. Modi gov't, which otherwise makes such a hue and cry over 'foreign interests', had played into their hands to force the poor in India to consume something untested.

Across the country, Shreegireesh found, the poor were complaining of this 'plastic rice' making it to their plates.

He brought out a complete set of internal gov't documents to demolish the governments propaganda around the scheme. And showed who the real beneficiaries of the scheme were - Corporates backed by dubious NGOs working for the corporate interests.

Now, the government has 'temporarily suspended' the scheme claiming its now learnt that fortified rice is not doing any good.

We still don't know the real reasons why it has done so. We will dig those out too.

Shreegireesh's reports and evidence was used in the courts.

It was picked up, plagiarised, copy pasted and replicated by others in media, sometimes with and sometimes without due credit.

Our reports were shortlisted for the world's biggest award for investigative journalism, the Fetisov award.

We were grateful for the straight and the backhanded compliments. But, most of all, we were happy that our work had put the truth out bluntly and with hard evidence.

I write this to explain, why investigative journalism is central to keeping those in power accountable. It is the essential form of journalism. It is effective, even if the wheels take time to turn.

We don't know why yet the government has finally stopped the distribution of the spurious artificial rice grain. We are glad it has.

Such journalism requires immense courage and resources. When you support it, you empower yourselves as citizens, to defend your rights and that of the poorest who have the least ability t hold the powerful to account.

Democracies need public-funded journalism to be better democracies.

Read Shreegireesh's work, if you had missed it then.

I will be teaching at a week-long SPARC Workshop on Neuromorphic Computing, to be held at IIT Roorkee. The workshop is being organized in memory of our friend, the late Prof. Brajesh Kumar Kaushik.

I will cover the basics of magnetism, magnetoresistance principles, and domain wall–based neuromorphic computing (approximately 10 hours in total, spread over 5 days).

There will also be other eminent speakers from the USA and India (from both universities and industry).

Interested students may scan the QR code for the registration link and details.

Please share to help reach a wider audience.
