Look closely, there is an elephant on that steep hill. Many people imagine elephants as animals of the plains. But the truth is far more fascinating. Asian elephants are remarkably sure-footed and can negotiate surprisingly steep hills and rocky slopes.
This photograph captures an elephant making its way across a steep hillside in the Nilgiris. And now, researchers have documented wild elephants in Arunachal Pradesh at an astonishing 3,266 metres above sea level, the highest elevation ever recorded for Asian elephants. This remarkable discovery reveals the extraordinary adaptability of these gentle giants and challenges one of the most enduring assumptions about them.
What a fascinating fact to learn on the eve of #WorldElephantDay2026, celebrated on 12 August!

I taught JEE physics for years. That paper breaks strong kids in three hours.
This exam is five hours of theory and five hours of lab work, and these five did close to perfect scores on it.
Let me tell you what actually happened.
The International Physics Olympiad is the world championship of school physics. It was the 56th edition. Held in Bucaramanga, Colombia, from July 5 to 12.
381 students. More than 85 countries. Every one of them the best physics student their country could find.
India sent five kids.
All five came back with gold.
Their names are Kanishk Jain from Pune. Riddhesh Anant Bendale from Indore. Rishit Garg from Dwarka in Delhi. Shresth Suraiya from Mumbai. Svarit Joshi from Ahmedabad.
We know a hundred cricketers by their nickname and not one of these boys. :)
That clean sweep put India at joint World Number One. Tied with China, Russia, Kazakhstan, South Korea and Taiwan.
Those are countries that pour serious money and national pride into science education. We are standing level with them.
Now here is what the exam actually was.
Two papers. Each five hours long.
The theory paper had three problems. One on the thermodynamics of paramagnetic cooling. One on the photoionisation of ozone. One on the dynamics of electron positron pairs.
The experimental paper was another five hours in a lab, working through heat transfer and thermodynamic processes in fluids.
That means you get given equipment you have never seen, and you have to design your own experiment, take your own readings, handle the errors, and reach a real answer.
Not multiple choice. No shortcuts. No pattern recognition. You either understand physics or you sit there for five hours.
HBCSE says the Indian students were near perfect on theory and excellent on the practical too.
Now, this was India's 27th appearance at the IPhO.
Across all those years, about 44 percent of Indian students have won gold, 41 percent silver, 10 percent bronze.
In the last ten years, every single Indian student has come home with a medal. 62 percent gold, 38 percent silver.
Not one kid has gone and come back empty handed in a decade.
Five golds in one year has happened only twice. This year, and in 2018.
So who built this.
The programme is run by HBCSE, the Homi Bhabha Centre for Science Education. It sits under TIFR, which sits under the Department of Atomic Energy.
They run the whole funnel. A national exam, then a national olympiad, then a brutal selection and training camp, and out of everyone in the country, five kids get on a plane.
The team was led by Professor Anwesh Mazumdar of HBCSE-TIFR and Dr Leena Joshi from St Xavier's College, Mumbai.
The scientific observers were Professor Ananda Dasgupta from IISER Kolkata and Nisha Kelkar from Gogate-Joglekar College in Ratnagiri.
Yes. Ratnagiri. A college in a small coastal town in Maharashtra.
This is public education doing something the private coaching industry could never do on its own.
The coaching industry is very good at one thing. Teaching you to solve a known problem fast.
That is what JEE and NEET reward, and I say that with love because I was part of that world.
But an olympiad paper does not have a known type. There is no shortcut chapter. There is no formula sheet that saves you. You have to sit with a problem you have never seen and think.
That is a completely different muscle. And a government funded centre has been quietly building it in Indian teenagers for 27 years.
So yes, be proud. Loudly.
HBCSE also shared that around 64 percent of India's olympiad medallists go on to do a PhD.
But only about 32 percent of medallists end up settling in India.
I do not say that to spoil the moment. These kids owe the country nothing. They earned every option they have.
But it should tell us something. We are excellent at finding this talent. We are excellent at training it. We are still not great at giving it somewhere worth staying.
Congratulations Kanishk, Riddhesh, Rishit, Shresth and Svarit. This is one of the best things an Indian did this year and most of the country will never hear about it.

“To beard the lion in his den.”
The dictionary defines it as boldly confronting a powerful rival on their own turf.
For years, Norway Chess has been Magnus Carlsen’s den. His turf. His domain.
So I woke up to this news and my jaw dropped.
You didn’t just win a title, @rpraggnachess.
You walked into the lion’s den and emerged victorious
This title is important. Not because of the trophy, but because of your challenger spirit.
And that’s something all of us can learn from…

Waqf Act 1995 (Thread)
Today we will talk about the most beautiful creation of Congress (For Muslims)
Congress gave 40% of Indian land to Muslims in 1947 but they were not satisfied with 40% so they brought Waqf Act
Let's talk about its wonderful provisions

Do you know about a greatest devotees of Bhagwan shiva who gave his eyes to Mahadev !
This two minutes story will give you goosebumps , read thread till end🧵
We often hear about the rupee appreciating or depreciating in the news, but many of us still find it confusing. So, today we’ll break down what’s happening and why it matters to all of us. A 🧵
Watch as Vanitha Mohan ma’am discusses the challenging situation faced by #Pricol #Coimbatore due to trade union protests and the tragic murder of a Pricol HR, highlighting the aftermath and the company’s path forward.
Dear Hon'ble Members of Parliament. It is better to be a hero who is forgotten than to be a coward who is remembered. Do not be cowards. Do the right thing. Do not amend the Waqf Act. Abrogate it.
Text of my letter to the Waqf Joint Parliamentary Committee:
From: Anand Ranganathan
To: <[email protected]>
Dear Hon'ble Members of Parliament,
Unjust, discriminatory, draconian acts are not amended, they are abrogated. Do not amend the Waqf Act; abrogate it.
World over, disputes over property are settled using existing laws that are community and religion-agnostic. Why should a particular religious community be armed with another set of laws, those that are patently discriminatory towards members of the other community, as a primary instrument of defence or, indeed, offence? Is there a Hindu equivalent of the Waqf Act? Promulgate one in the interest of equality, then. Let those who want continuation of the Waqf Act watch as Hindus lay claim to thousands of mosques and Muslim villages and enjoy the privilege of the disputes being addressed primarily not through the courts but via the clauses and strictures of Hindu equivalent of the Waqf Act.
Amending the Waqf Act is akin to chopping the head of a hydra. This is because, while you might have removed a few discriminatory and draconian clauses from the Act, a vast majority of them remain untouched - Sections 28, 8, 101, 54, to name a few.
I refuse to suggest amendments to the Waqf Act. I demand its abrogation.
The Waqf is a parallel government being run by the State. In its board, it has its own legislature; in its surveyor it has its own executive; and in its tribunal it has its own judiciary. If India is to be saved from becoming an Islamic republic, the Waqf board shouldn’t just be amended, it should be abrogated.
It is better to be a hero who is forgotten than to be a coward who is remembered. Do not be cowards. Do the right thing.
Sincerely,
Anand Ranganathan
Just a quick timeline for everyone to consider:
Biden says 20x that he’s not dropping out and that he won’t be pushed out by party elites.
He gets COVID.
Goes out of sight for a few days.
His campaign co-chair says emphatically that Joe is NOT leaving the race. Period.
A few hours later his X account posts that he IS leaving the race via a screenshot document with absolutely no proof that he’s behind it.
Joe Biden’s campaign aides and staff say that they found out via @X, not from the Biden’s.
24 hours later, Joe still hasn’t shown his face to confirm that it’s his statement but Kamala secured enough delegates to be the nominee within those 24 hours since his post.
@JoeBiden’s @X account now has a Kamala ad as his profile header, their campaign HQ has been redone to eliminate Biden name.
Kamala holds a small event where she begins to say that he’s on a "recor…." Then says "phone" and we hear a strange back and forth that feels totally unnatural. All of this is via phone like we’re living in the 1940’s glued to the radio for news. No visual is shown of him.
All of this occurs with no proof that it’s Joe.
Maybe he did this but even if he did, this is BIZARRE and yet the media is pretending it’s normal.
None of this is normal. Thank God we have @X so they can’t control this entire narrative. Eventually all of it will fall apart. Watch.
Might be hard to believe today, but once upon a time, in 1971, Tamilnadu was one of the two states within the country, to have total prohibition of alcohol in force. Along with Gujarat.
This is the story of who implemented Prohibition in TN and who lifted it, and why : (1/8)
🐟 2023 was a bumper year for removing Europe's obsolete barriers! A new report found that 487 barriers like dams and weirs were removed — up nearly 50% on last year's record.

Just as a healthy Foundation is integral to a strong and sustainable structure, healthy Soil is integral to the integrity and cohesiveness of the planet. For the very first time, Soil–which is the Foundation of Life on this planet– is moving toward centerstage in the ecological narrative. How quickly & how effectively we Act to restore soil health could well determine the perpetuity or otherwise of the human race. -Sg

Prepositions Of Time
கடற்கரையோரம் இருந்த மஞ்சள் ஆறு பாசன பகுதிகள் பாலைவனமானது. மிகப்பெரிய பாதிப்பை சந்தித்த சீனா தற்போது அதை சரி செய்ய முயன்று வருகிறது.
அதுபோல காவிரி நீர் கடலில் கலக்காவிட்டால் காவிரி கழிமுக மாவட்டங்கள் பால��வனமாகும்.
நம் மாநிலத்திற்குள் அணைகளே கட்டக்கூடாது என நான் சொல்லவில்லை. அணைகள் கட்டி அந்த தண்ணீர் ஏரி, குளங்களில் சேமிக்கப்பட்டாலும் குறிப்பிட்ட அளவு தண்ணீர் கட்டாயம் கடலில் கலந்தேயாக வேண்டும்.
அணைகள் பற்றி பேசுவோம். கர்நாடகாவிலிருக்கும் KRS, கபினி, ஹேரங்கி, ஹேமாவதி அ��ைகளில் தேக்கப்படும் தண்ணீரை நம் மேட்டூர் ஸ்டேன்லி அணை என்ற ஒரு அணையில் தேக்கிவிடலாம். இந்த 5 அணைகளில் மேட்டூர் அணைதான் மிகப்பெரியது.
கர்நாடகத்திலிருக்கும் அனைத்து அணைகளும் மலைப்பாங்கான மேட்டு நிலத்தில் இருக்கும் அணைகள்தான்.
ஆனால் தமிழகத்தில் மேட்டூருக்கு கீழே அப்படிப்பட்ட நில அமைப்பு இல்லை. காவிரி டெல்டா மாவட்டங்கள் சமவெளிப்பகுதிகளை கொண்டது. அதில் கிருஷ்ணராஜ சாகர், மே��்டூர் ஸ்டேன்லி போன்ற அணைகளை கட்ட முடியாது ஆனால் சிறு சிறு தடுப்பணைகளை மட்டும் கட்ட முடியும்.
இது பூகோள ரீதியில் உள்ள நீர் வடி நிலம், டெல்டா சமவெளி.
சிலர் கல்லணை மட்டும் டெல்டா பகுதியில் இல்லையா என கேட்கலாம்.
ஆம். கேள்வி சரிதான்.
கல்லணை ஒன்றும் நீங்கள் நினைப்பதுபோல் டி.எம்.சி கணக்கில் நீரை தேக்கி வைத்து வறட்சி காலத்தில் திறந்துவிட்டு பயன்படுத்தும் அணை கிடையாது. அது ஓடும் காவி���ியின் குறுக்கே தண்ணீரை தடுத்து நிறுத்தி பல சிறு சிறு வாய்க்கால்களுக்கு பிரித்து அனுப்பும் ஒரு மிகப்பெரிய மதகு போன்றது. கல்லணையில் ஒரு டி.எம்.சி நீரை கூட தேக்க முடியாது.
காவிரி நதியை பொறுத்தவரை மேட்டூர் ஸ்டேன்லி நீர் தேக்கம் ஒன்று மட்டுமே போதும்.
அதிலிருந்து வரும் தண்ணீரை சேமிக்க முயற்சிக்கலாம்.
நிறைய சிறு சிறு தடுப்பணைகள் கட்டி நிலத்தடிநீர் மட்டத்தை உயர்த்தலாம், அந்த நீரை ஏரி, குளங்களில் சேமிக்கலாம்.
ஆனால் ஒரு சொட்டு தண்ணீரை���்கூட கடலுக்கு விடமாட்டேன் என நாம் நினைத்தால் இயற்கை நம்மை பழிக்கும்.
டெல்டா மாவட்டங்களில் மிகப்பெரிய அணையை கட்டுவேன் என யாராவது சொன்னால் அது கற்பனையாகத்தான் இருக்கும்.
உண்மையில் காவிரி டெல்டா சமவெளியில் பெரிய அணைகளை கட்ட முடியாது. சிறு, குறு தடுப்பணைகளை மட்டுமே கட்ட முடியும்.
காவிரி டெல்டா மாவட்டங்களில் நிறைய தடுப்பணைகளை கட்டிக்கொள்ளாதது நம்முடைய தவறுதான். தர்க்க ரீதியில் தவறுதான் ஆனால் இயற்கையை நாம் மாற்ற முயற்சிக்கவில்லை என்ற வகையில் அது சரி.
இதற்காக நமக்கு காவிரியில் உரிமை இல்லாதது போலவும், கர்நாடகாவை தொந்தரவு செய்வது போலவும் யாரும் பேசாதீர்கள்.
சர்வதேச நதி நீர் தாவா சட்டத்தின்படி ஒரு நதி ��ீது அதிக உரிமை அதன் கீழ் பகுதியில் இருப்பவர்களுக்குத்தான்.
நமது உரிமையைத்தான் கேட்கிறோம் பிச்சை அல்ல. நமது அரசியல் சண்டைக்காக நமது உரிமையை ஏளனப்படுத்தாதீர்கள்!
முடிவாக ஒன்று. காவிரியில் நமக்கு இருக்கும் உரிமை போன்றே வங்கக்கடலுக்கும் உரிமை இருக்கிறது. பல லட்சக்கணக்கான ஆண்டுகளாக காவிரி நீரை வங்கக்கடலும் குடித்து வந்திருக்கிறது. அதை கர்நாடகாவும், நாமும் முழுவதும் எடுத்து���்கொண்டால் இயற்கைக்கான பங்கை யார் கொடுப்பது?
