Starting a new (ad)venture
A YouTube channel dedicated to discussing physics ideas for entrepreneurs
I bring ideas from an ocean of physics and present them to anyone interested in using them for business and entrepreneurship. These are not physics lectures, but discussions on ideas with a perspective of economic utility.
As with all my ventures, it is open source.

The first video is out:
I see that the essay I wrote on CV Raman and made open access (thanks to Resonance, which published it) has been used by several educators on YouTube, including some in Indian languages. Also, the Google AI overview shows the published essay as the main reference for a search related to Raman’s science communication (see slideshow below).
I am glad to see that making one’s writing open to all has positive effects. Open-access, not just for readers, but also for authors, is beneficial. Especially in India, paywalls for science are a detriment.
My worry is that open-access publishing has been mainly driven by commercial publishers that extract huge funds from the publishing authors. This defeats the purpose of open science, especially when the research of an author is publicly funded. Added to that, Indian researchers and writers cannot afford to pay huge sums for publishing articles and books.
The publication landscape (including journals and books) across the world needs an introspection. Open-access model is effective only when the readers and authors have access to that model. Otherwise, the model becomes a paywall for authors.

Recently, I was talking to a college student who had read some of my blogs. He was interested in knowing what it means to humanize science. I told him that there are at least three aspects to it.
First is to bring out the wonder and curiosity in a human being in the pursuit of science. The second was to emphasize human qualities such as compassion, effort, mistakes, wrong directions, greed, competition and humour in the pursuit of science. The third thing was to bring out the utilitarian perspective.
The student was able to understand the first two points but wondered why utility was important in the pursuit of humanizing science. I mentioned that the origins of curiosity and various human tendencies can also be intertwined with the ability to use ideas. Some of the great discoveries and inventions, including those in the so-called “pure science” categories, have happened in the process of addressing a question that had its origin in some form of an application.
Some of the remarkable ideas in science have emerged in the process of applying another idea. Two great examples came into my mind: the invention of LASERs, and pasteurization.
I mentioned that economics has had a major role in influencing human ideas – directly or indirectly. As we conversed, I told the student that there is sometimes a tendency among young people who are motivated to do science to look down upon ideas that may have application and utility. I said that this needs a change in the mindset, and one way to do so is to study the history, philosophy and economics of science. I said that there are umpteen examples in history where applications have led to great ideas, both experimental and theoretical in nature, including mathematics.
Further, the student asked me for a few references, and I suggested a few sources. Specifically, I quoted to him what Einstein had said:
“….So many people today—and even professional scientists—seem to me like someone who has seen thousands of trees but has never seen a forest. A knowledge of the historic and philosophical background gives that kind of independence from prejudices of his generation from which most scientists are suffering. This independence created by philosophical insight is—in my opinion—the mark of distinction between a mere artisan or specialist and a real seeker after truth..”
The student was pleasantly surprised and asked me how this is connected to economics. I mentioned that physicists like Marie Curie, Einstein and Feynman did think of applications and referred to the famous lecture by Feynman titled “There is Plenty of Room at the Bottom” (1959).
To give a gist of his thinking, I showed what Feynman had to say on miniaturization:
“There may even be an economic point to this business of making things very small. Let me remind you of some of the problems of computing machines. In computers we have to store an enormous amount of information. The kind of writing that I was mentioning before, in which I had everything down as a distribution of metal, is permanent. Much more interesting to a computer is a way of writing, erasing, and writing something else. (This is usually because we don’t want to waste the material on which we have just written. Yet if we could write it in a very small space, it wouldn’t make any difference; it could just be thrown away after it was read. It doesn’t cost very much for the material).”
I mentioned that this line of thinking on minaturization is now a major area of physics and has reached the quantum limit. The student was excited and left after noting the references.
On reflecting on the conversation, now I think that there is plenty of room to humanize science.
In recent years, this has been one of the best books on the history of mathematics in India. The late Prof. Divakaran was a theoretical physicist and a scholar.
This book is also an excellent example of how a scientist can present historical facts and analyse them with rigour and nuance. Particularly, it puts the Indian contribution in the global context and shows how ideas are exchanged across the geography. The writing is jargon-free and can be understood by anyone interested in mathematics.
Unfortunately, the cost of the book ranges from Rs 8800 to Rs 14,000 (depending on the version), which is a shame. Part of the reason why scholarly books, particularly in India, don’t get the traction is because of such high cost. This needs to change for the betterment and penetration of knowledge in a vast society such as India.
There is a nice video by numberphile on Prof. Divakaran and his book:
Recently, I saw the following tweet from the well-known historian William Dalrymple.
Congrats to the listed authors, who deserve rewards (and the money) for their effort.
I have 3 adjacent points to make:
1) India badly needs to read (and write) more on science and technology. Here, I am not referring to textbooks, but some popular-level science books (at least). Generally, educated Indians are exposed to science only through their textbooks, which are mostly dull, or, in this era, YouTube videos, which have a low signal-to-noise ratio. Good quality science & tech books at a popular level can add intellectual value, excitement, and expand scientific thinking via reading, not just in students, but also in adults.
2) In India, most of the non-fiction literature is dominated by the social sciences, particularly history (as seen in the best-seller list). I have no problem with that, but non-fiction as a genre is a broad tree. Indian readers (and publishers) can and should broaden this scope and explore other branches of the tree. Modern science books (authentic ones), especially written in the Indian context, are badly in need. I hope trade publishers are reading this!
3) Most of the public and social media discourse in India does not emphasize (or underplays) the scientific viewpoint. Scientific literature and scientific discourse should become a central part of our culture. Good books have a major role to play. Remember what Sagan’s Cosmos did to American scientific outlook, and indirectly to its economic progress. The recent Nobel in economics, especially through the work of Joel Mokyr, further reinforces the connection between science, economics and human progress. This realization should be bottom-up, down to individual families and public places.
One of the great scientists, James Maxwell, is attributed to have said: “Happy is the man who can recognise in the work of today a connected portion of the work of life and an embodiment of the work of Eternity.…“
Science, with its rich, global history and philosophy, in the form of good books, can connect India (and the world) to the ‘work of eternity’, and make us look forward.
Embedding science within culture, in a humane way, can lead to progress. Science books have a central role to play in this.

Reproducing one of Da. Ra. Bendre’s Kannada poems titled “ಹಕ್ಕಿ ಹಾರುತಿದೆ ನೋಡಿದಿರಾ?” which translates to Have You Seen the Bird Flying?
A comment on the poem: In my reading, this poem is a metaphor for the exploration of the universe through the exploration of a bird. The poet periodically asks: “Have you seen the bird flying?”, thereby motivating the reader to observe what the bird may be seeing and doing. It is a poem read by school children, but there is a deeper philosophical meaning in asking humans to look up at the sky and realize the flight of a bird in themselves. YouTube also has the original audio of Bendre reciting the first few lines of the poem, and it is worth listening to.
Below is the poem, followed by a decent translation.
“ಹಕ್ಕಿ ಹಾರುತಿದೆ ನೋಡಿದಿರಾ?”
ಇರುಳಿರುಳಳಿದು ದಿನದಿನ ಬೆಳಗೆ
ಸುತ್ತಮುತ್ತಲೂ ಮೇಲಕೆ ಕೆಳಗೆ
ಗಾವುದ ಗಾವುದ ಗಾವುದ ಮುಂದಕೆ
ಎವೆ ತೆರೆದಿಕ್ಕುವ ಹೊತ್ತಿನ ಒಳಗೆ
ಹಕ್ಕಿ ಹಾರುತಿದೆ ನೋಡಿದಿರಾ?
ಕರಿನೆರೆ ಬಣ್ಣದ ಪುಚ್ಚಗಳುಂಟು
ಬಿಳಿ-ಹೊಳೆ ಬಣ್ಣದ ಗರಿ-ಗರಿಯುಂಟು
ಕೆನ್ನನ ಹೊನ್ನನ ಬಣ್ಣಬಣ್ಣಗಳ ರೆಕ್ಕೆಗಳೆರಡೂ ಪಕ್ಕದಲುಂಟು
ಹಕ್ಕಿ ಹಾರುತಿದೆ ನೋಡಿದಿರಾ?
ತಿಂಗಳಿನೂರಿನ ನೀರನು ಹೀರಿ
ಆಡಲು ಹಾಡಲು ತಾ ಹಾರಾಡಲು
ಮಂಗಳಲೋಕದ ಅಂಗಳ ಕೇರಿ
ಹಕ್ಕಿ ಹಾರುತಿದೆ ನೋಡಿದಿರಾ?
ಮುಟ್ಟಿದೆ ದಿಙ್ಮಂಡಲಗಳ ಅಂಚ
ಆಚೆಗೆ ಚಾಚಿದೆ ತನ್ನಯ ಚುಂಚ
ಬ್ರಹ್ಮಾಂಡಗಳನು ಒಡೆಯಲು ಎಂದೋ
ಬಲ್ಲರು ಯಾರಾ ಹಾಕಿದ ಹೊಂಚ
ಹಕ್ಕಿ ಹಾರುತಿದೆ ನೋಡಿದಿರಾ?
Translation (ChatGPT):
Have You Seen the Bird Flying?
(by D. R. Bendre — English rendering)
Night after night melts into day,
All around, above and below —
the world moves on and on,
as the moment of awakening opens —
Have you seen the bird flying?
It has a tail dark as rainclouds,
and feathers white, shining bright;
its wings on either side
are tinted with colors of gold and light —
Have you seen the bird flying?
It drinks the silvery water of the moon,
to play, to sing, to soar;
it enters the courtyard of the blessed world —
Have you seen the bird flying?
It’s touched the edge of the horizon,
stretched its beak to the farthest reach;
who knows — since when it has tried
to break open the universe itself —
Have you seen the bird flying?
A nice article by @RutujaUgale in @Sci_Rio that discusses public engagement by scientists as influencers of scientific thought.
Thanks, Rutuja, for profiling my blog, ‘Vismaya’.
Here is my quote from the article:
“For me, there are two implications of doing science. One is that science is extremely useful to society, and the second is that it is a good, thoughtful way of living one’s life. Communicating the second implication is important to me, and I do this by researching, writing, and podcasting about the history and philosophy of science (physics in particular). This path helps people understand the human element of doing science and reveals a context. Some of my blogs (filtered here) discuss why I do science and how I do it. More than ‘influencing’ the audience, I am interested in inviting them to explore science by themselves via their own curiosity. That is one reason why my blog is called VISMAYA.”

When we remember and talk about building modern, scientific India, we must acknowledge past scientists who played a critical role in taking ideas and turning them into reality. Homi Bhabha (image on left) was one of the pioneers. But we must also remember many unknown people of India who literally built modern scientific facilities, such as the CIRUS nuclear reactor (image on right is from 1958). Although their faces are invisible, their contributions should not be.
Meghnad Saha (6 October 1893 – 16 February 1956), of the fame of Saha’s ionization formula, was born this day. In 1993, a postage stamp in India was released commemorating his birth centenary.
Saha was an astrophysicist with a broad knowledge and appreciation of various branches of physics. One of the earliest English translations (1920) of the papers on relativity by Einstein and Minkowski was written by Meghnad Saha and S.N.Bose.
At the beginning of the book, Mahalanobis introduces the topic with a historical introduction. He begins with a thoughtful discussion on experiments that eventually ruled out the presence of ether, and it sets the stage as follows:
“Lord Kelvin writing in 1893 in hig preface to the English edition of Hertz’s Researches on Electric Waves, says many workers and many thinkers have helped to build up the nineteenth century school of plenum, one ether for light, heat, electricity, magnetism; and the German and English volumes containing Hertz’s electrical papers, given to the world in the last decade of the century, will be a permanent monument of the splendid consummation now realised.”
Ten years later, in 1905, we find Einstein declaring that “the ether will be proved to be superflous”. At first sight the revolution in scientific thought brought about in the course of a single decade appears to be almost too violent. A more careful even though a rapid review of the subject will, however, show how the Theory of Relativity gradually became a historical necessity.
Towards the beginning of the nineteenth century, the luminiferous ether came into prominence as a result of the brilliant successes of the wave theory in the hands of Young and Fresnel. In its stationary aspect, the elastic solid ether was the outcome of the search for a medium in which the light waves may “undulate.” This stationary ether, as shown by Young, also afforded a satisfactory explanation of astronomical aberration. But its very success gave rise to a host of new questions all bearing on the central problem of relative motion of ether and matter.“
Saha, in various capacities, took a stance against British colonialism. Although it affected some opportunities, he continued to do science and was recognized for his outstanding contributions. As Rajesh Kochhar mentions:
“Saha had wanted to join the government service, but was refused permission because of his pronounced anti-British stance. For the same reason, the British government would have liked The Royal Society to exclude Saha. It goes to the credit of the Society that it ignored the pressures and the hints, and elected him a fellow, in 1927. This recognition brought him an annual research grant of £300 from the Indian government followed by the Royal Society’s grant of £250 in 1929 (DeVorkin 1994, p. 164).“
Saha led a tough life. He not only had to face suppressive British colonial rule but also academic politics and battles (versus Raman, no less). His knowledge of physics, his contributions to Indian science, and his commitment to people (he was a politician too) were significant. Let me end the blog with a few lines from Arnab Rai Choudhuri’s article, which nicely summarizes Saha’s work (specifically his ionization formula), and his scientific life:
“Saha’s tale of extraordinary scientific achievements is simultaneously a tale of triumph and defeat, a tale both uplifting and tragic. Saha showed what a man coming from a humble background in an impoverished colony far from the active centres of science could achieve by the sheer intellectual power of his mind. But his inability to follow the trail which he himself had blazed makes it clear that there are limits to what even an exceptionally brilliant person could achieve in science under very adverse circumstances.“
India and Indian science should remember Meghnad Saha.
