An Indian scientist who demonstrated to the world that plants have life.

On May 10, 1901 at jam-packed hall of Royal Society, London he demonstrated how plants have life with crescograph. Invented telegram. Remembering JC Bose, 1st modern scientist of India on birth anniversary.
He could record motion of plant tissues to about 10 K times of their actual size.

Demonstrated how Plant died like a rat due to poisoned bromide solution.

JC Bose became the first Indian to be appointed as Professor of Physics in the Presidency College, and later to IES.
JC Bose was Offered half payment vis-a-vis European professors, in protest refused salary for 3 years and taught.

In 1998, Dr. Probir found out how Bose was the real inventor of Wireless Receiver, didn't patent, but Marcony patented.

Remembering the giant. #JCBOSE
Prior to his death in 1937, Bose set up the Bose Institute at Calcutta.

He was elected the Fellow of the Royal Society in 1920 for his amazing contributions and achievements.

How Bose was behind invention of Telegraph [ 3, Proc. IEEE, Vol. 86, No. 1, January 1998.]
Among his students notable were PC Mahalanobis, Meghnad Saha, SN Bose etc.

Here is an Indian who has a crater on Moon named after him. To recognise his achievements in radio communication which paved way for satellites later.

Today severe cyclone Nivar will hit eastern coast of India. In 12 seconds learn how coastal green shelter belts check tsunami & cyclones. Dutch research institute Deltares.
We are facing one more #cyclone today. So let me remind you. #Mangroves;

- acts as buffer & reduce impact of cyclones & #storm surge.
- they break the #wind force
- provide #habitat to #animals during cyclone or otherwise
- they reduce #pollution.

We just need to protect them.
So how it works. Mangroves create a maze & dense habitat. With species which are salt tolerant & have special adaptations. They act like buffer & which slow down wind & consume energy. So after passing, the storms get dampen. You must have read in ‘Theory of Vibration’.

This is how yesterday female elephant from Dharmapuri, TN was rescued. Which fell in open well. After hours of operation, which included supplying food also, the elephant is rescued by forest team. It was a 50 feet deep well. And credits to the elephant also for her will. @ANI
Open wells & ditches in elephant migratory routes are huge problems for these animals. Since they are long ranging creatures, migrate to long distances for food & water.

Least we can do is cover such wells or keep safety wall. Imagine it was a 50 feet deep well.
It took a complete day for the forest staff to rescue the female elephant from 50 feet deep well. Every such rescue is a unique case where strategy is adopted based on circumstances.

Kudos to all involved in this one.

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.

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.

Boss was none other than APJ Abdul Kalam.

Remembering Kalam sir on his #BirthAnniversary 3/3
