A case for compassionate rationality

Nowadays, it is very common to see various advertisements and social media posts where blatantly unscientific and irrational suggestions are explicitly presented, and even celebrated.

Perhaps this is one of the best ways to avoid probabilistic thinking, which is not natural to human beings. Irrationality attracts a lot of people, and those who understand this utilize it for their benefit. It is the fastest way to group people into a stream as you don’t need to explain. The burden of explanation is always on the rational and not on the irrational. Essentially, it is an asymmetric game.

Generally, any explanation leads to more questions. These questions can further lead to enquiry and that has a cognitive cost. Irrationality does not have to pay that cost.

This has been happening for ages, just that their forms keep changing. It is important to emphasize that cultures across the world, including India, have elements of spirituality and rationality.

Most of the time, the spiritual element is over-emphasized, whereas the philosophical and rational aspect is not given the same prominence. If you dig deeper into any culture, it is the philosophical and rational that has elevated the thought process by asking probing questions, but it is the spiritual which captures the attention.

One way to overcome this problem is to emphasize the rational aspect of the culture. If people start appreciating the fact that there were many people from their own cultural roots who did think deeply and questioned everything, then there is a historical connection. Importantly it leads to a realization that rationality is not something foreign but a cultivated human behavior indigenous to ones own culture.

This is where I make a case for compassionate rationality. It is important that we take the path of patience and explain the gravitas of rationality and its cultural roots without being condescending in our tone and in our thoughts. We need to emphasize its benefits compared to blind faith. We need to make a strong case that rationality has a historical past in our own culture, and importantly it has utility in the present and in the future.

After all, being an atheist/rationalist is not incompatible with being an empathetic and compassionate person. One can still not believe in god and appreciate the cultural roots. One can still go to a temple/mosque/church/any place of worship and be in awe of the architectural beauty and creativity. One can still have a friend who is deeply religious, and have a meaningful argument.

One can still be rational and human.

Podcast: Gripping History of Laser Invention

I tell the story behind laser invention. It is a story of human imagination, tenacity, device invention, intense competition, blame and humour. I discuss how the Cold War era USA created an environment to innovate and compete, all thanks to Sputnik…

Kamala Sohonie and Iravati Karve


Great to see Kamala Sohonie featured on google doodle today. She was (probably?) the 1st woman to get a science PhD in India – circa 1939.
Also featured in the book “Lilavati’s Daughters” which I mentioned in my recent podcast

Going by the timelines, Iravati Karve got PhD in 1930, in anthropology, which is generally categorized as ‘social science’. Nevertheless, all inspiring.
Iravati had deep connections with Pune, and taught Deccan College

Two Chandrasekhars and their students

I discuss the legacy of two important individuals Subrahmanyan Chandrasekhar and Sivaramakrishna Chandrasekhar and their students. I highlight their styles of doing research and how they inspired important schools of thought. I emphasize the role of economic privilege and gender. I discuss Bimala Buti and mention about interesting books on women in science : Lilavatis Daughters and Lab Hopping.

Michelson’s legend in a poem

Albert A Michelson. Image credit : Nobel Prize webpage

Albert Abraham Michelson was a celebrated American experimental physicist. He was associated with one of the most famous experiments in physics : Michelson-Morley Experiment, which formed an important input for Einstein’s special theory of relativity.

Recently, I discussed about this experiment in one of my podcasts.

Michelson’s ability to design and develop optical instruments including the interferometer named after him, was one of vital elements in his legendary pursuit to measure velocity of light. He continued to refine this measurement over a period of 40 years or so.

He was also the first American to win a Nobel prize in science (physics, 1907). Americans adored him, and he shot up to fame with his ingenious experiments and became a folklore of United States.

There is a very nice historical account of the Michelson-Morley-Miller experiment in the book titled : The Ethereal Aether; a History of the Michelson-Morley-Miller Aether-Drift Experiments, 1880-1930. by Swenson, Loyd S. published in 1972.

(Yes, you read it right, there was another guy called Dayton Miller who played a critical role in refining the experiment initiated by Michelson and Morley )

In Swenson’s book, there are two stanzas from a poem by Edwin Herbert Lewis that highlights Michelson’s legend. Below I reproduce the same :

But in Kyerson rainbows murmur the music of heavenly things.
Is not this stranger than heaven that a man should hear around
The whole of earth and the half of heaven and see the shadow of sound?
He gathereth up the iris from the plunging of planet’s rim
With bright precision of fingers that Uriel envies him.
But when from the plunging planet he spread out a hand to feel
How fast the ether drifted back through flesh or stone or steel
The fine fiducial fingers felt no ethereal breath. They penciled the night in a cross of light and found it still as death.
Have the stars conspired against him? Do measurements only seem?
Are time and space but shadows enmeshed in a private dream?

But dreaming or not, he measured. He made him a rainbow bar,
And first he measured the measures of man, and then he measured a star.
Now tell us how long is the metre, lest fire should steal it away?
Ye shall fashion it new, immortal, of the crimson cadmium ray.
Now tell us how big is Antares, a spear-point in the night?
Four hundred million miles across a single point of light.
He has taught a world to measure. They read the furnace and gauge
By lines of the fringe of glory that knows nor aging nor age.
Now this is the law of Ryerson and this is the price of peace-
That men shall learn to measure or ever their strife shall cease.

E.H. Lewis

Indeed humans shall learn to measure or ever their strife shall cease…
