In 1930, anticipating the Nobel Prize, CV #Raman bought two tickets to Stockholm, other for his wife, as early as September, 3 months early.
His conviction was not misplaced; was decorated with the Nobel Prize for Physics that year for his path-breaking work. #BirthAnniversary
Raman was also the first Non white to get Nobel Prize in science. It took merely Rs.200 to make this discovery & now millions of rupees.
University of Cambridge offered him a Professor’s job.
He rejected & later appointed as 1st Indian Director of IISc Bangalore in 1933.
Later he wrote his experience of sitting under Union Jack while recieving the prize. How it led to his breakdown.
During WW2 tried best to bring some scientists to work in #IISc, including Niel Bohr, Heisenberg, Pauli. & Max Born spend some time here.
CV Raman studied Science, but got selected in Indian Financial Service. Was in good poaition. But later returned back to world of science.
When Sarabhai came to India during WWII his guide told him he must work under CV Raman at IISc then only he will consider his work worthy.
And very few knows Raman was doctoral advisor of Vikram Sarabhai.
It was time when Bhabha, Raman & Sarabhai walked the corridors of IISc.
India celebrates National Science Day on 28th Feb. Day when CV Raman discovered the Raman Effect.
Let's remember genius on his birth Anniversary. 🙏🏻🙏🏻
Well this thread reached back to me via whatsapp. That completes the circle. As happening many a times these days. Thanks to all for sharing the positive messages.

Amur falcons are back to India. Let me share story, a bird which crosses Himalayas enroute to India from Mongolia & Arabian Sea for going to Africa. This bird covers 22,000 KMs flying. One of the nature’s amazing wonder. In Nagaland they come in hundreds of thousands & stay. 1/n
While we were inside. Irang an Amur falcon was radio tagged by WII in Manipur. It went to South Africa, returned back to China. On October it again started journey. And in one year it covered 29,000 kms & back to Manipur. Which machine can beat that.
In one study three Amur falcons were radio tagged named as Naga, Pangati & Wokha. By 13 November they left Nagaland & by 25th December all three were in Southern Africa. With some halts in India. They took longest over water journey. Imagine the distance they covered flying.
During a significant project of DRDO, the work pressure was high. A scientist approached his boss – & asked to leave early that day considering he had promised his children to take them to an exhibition.
Boss generously granted permission, the scientist got back to work. 1/3
When he did, he lost the track of time & forgot to leave early. He reached home, feeling guilty, looked for his kids, but could only find his wife.
He asked for kids, and to his surprise she told him: “your manager was here around 5:15 and he took kids for exhibition!”. 2/3
Apparently, Boss had been observing the scientist and noticed that he might never realise he had to go home. Feeling for the kids, he decided to take the kids in his stead.
India will soon be the fourth country to have hypersonic missiles. After US, Russia & China only.
Congratulations to all scientists. 1/n
Hypersonic missiles fly with more than 5 Mach speed. Which means five times speed of sound. Supersonic is more than Mach 1.
They use SCRAMJET engines. Higher version of RAMJET engines, in short Supersonic Combustion RAMJET (SC+RAMJET) engines. 2/n
Ramjet engine works on principle of Ram effect. Which in simple terms utilising vehicular speed for compression.
But for combustion speed need to be slowed down. Combustion at Sub sonic speed. Which means during expansion there is a check on velocity of vehicle. 3/n
They are ecosystem doctors. But in recent years we have lost 90-99% of vulture population in India. Eg white-backed vulture faced a 99.9% decrease whereas slender-billed & long-billed vulture faced 97% decrease.
Many reasons for their decline. But prime reason behind reduction in Vulture population in India was use of Diclofenac in cattle drugs. This cause acute renal failure & they die.
That is why now diclofenac is banned in cattle drugs.
Many conservation breeding programs are also ongoing with good results from Pinjor to Buxa. Where they are raised & later released in wild.
Some of them are equipped with Platform Terminal Transmitters for tracking & to keep a close watch. For study also.
