प्रकृति: रक्षति रक्षिता ! Mangrove forest after a cyclone. The line of defense after a cyclone.

#Mangrove; not only home for various species but also a tool against #Disaster. Tropical country like India, with densely populated 7500 km long coastline, will be effected by cyclones more due to #ClimateChange. This salt tolerant species acts as a shield against cyclones. 2/n

So how it works. Reposting my old tweets. Mangroves create a maze & dense habitat. With species which are salt tolerant & special adaptations. They act like buffer & consume the winds & energy. So after passing the storms get dampen. 3/n

It was May 10, 1901. The central hall of the Royal Society in London was jam-packed with famous scientists. Everyone seemed to be curious to know how Sir JC Bose’s experiment will demonstrate that plants have feelings like other living beings and humans. He did it wonderfully.1/n

He demonstrated it wonderfully with his invention called as Crescograph.

So rightly called as First Modern scientist of India.

Sir JC Bose was the first Indian to be appointed Professor of Physics in the Presidency College. 2/9

His appointment was strongly opposed by britishers.

In those days one can be appointed to Imperial Education Service only through nomination, unlike IAS.

And he was appointed only when Lord Ripon personally intervened. 3/n

And all the five jungle cat cubs were saved. Found by farmers during harvesting in a field.

All were so small that they could not have been survive without mother.

So we decided to reunite them with mother.

The area was cordoned off. Where they were found villagers decided to stop harvesting for the time being.

Camera traps were established in the area carefully.

Teams and villagers stationed for the night near the location. So that they can be monitored and no disturbance occur.

In 1930, anticipating Nobel Prize, CV Raman bought two tickets to Stockholm, other for wife, as early as September, 3 months early.

His conviction was not misplaced; he 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 Non British Director of IISc Bangalore in 1933.

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 position. But later returned back to world of science.

What does this marginal change in global average temperature means. For life and climate on earth. Pay attention.

Difference it will make to wildfires.
