Savyasachi is an astrophysicist, an instrumentation (radio frequency) expert, a data analysis / machine learning / AI / neuroscience enthusiast and a former poet. He has a PhD in Astrophysics from the University of Wisconsin-Madison (UW-Madison), where he received a Jansky Fellowship (2006-2007). Over the last decade, teaching has been a passion, as also mentoring and guiding school and undergraduate students. He has headed curriculum reform at IIT Indore. His teaching philosophy and practice is to get the students to be “hands-on”, so that the classroom and the lab are a single resource for students, and therefore should be integrated. In other words, the classroom MUST be a laboratory where students toy with explanations and stitch them together to understand, explore, and create, with the mentor / teacher guiding them along.

His current research focus is radio astronomy instrumentation and galaxy clusters, especially radio observations of cluster mergers. Based on their work on galaxy cluster mergers, Savyasachi and Abhi are leading a project on making India’s first radio observatory inside an institute / university. This project is funded by DST-SERB. With collaborators, he discovered the first non-thermal Sunyaev-Zeldovich effect at cm wavelengths, which is a step towards estimating the total energy budget of galaxy clusters, currently ill-constrained. This is one of the main aims of his research.

Currently upskilling in Machine Learning and AI, Savyasachi also dabbles in tinkering with small electronic equipment and now offers solutions for small electronics and communications needs, with collaborators.

The straitjacketed bio over, here's the reality. With a highly non-linear trajectory throughout his life, he is a lazy dreamer and tends to generally swim against any tide he finds himself in..ecumenically, grammatically, mathematically, physically and psychologically. He is a failure by any sensible standards, and a mad, bad egg - contact at your own risk.

Why chetterhummin

In Isaac Asimov's Foundation universe, the motivation for psychohistory arose from the general idea of preserving humanity. Ironically, this idea was formulated by two robots - R. Daneel Olivaw and R. Giskard Reventlov as the Zeroth Law of Robotics. 

R. Daneel Olivaw lives on and lays the foundation of the Galactic Empire, and assumes two identities in the reign of Cleon I: 

  1. Eto Demerzel, the Emperor's trusted Minister
  2. Chetter Hummin, a mischievous reporter who inspires and pushes Hari Seldon to formulate psychohistory as a science. His name is a play on the words cheater and human. So, his name can be interpreted in a myriad of ways. The way I choose to interpret it is as follows. R. Daneel Olivaw cheats the death of human civilization through his invention of psychohistory. He is therefore the most compassionate of humans...hence the name of this website.

Thence Flows Life

The valley laments its distance from the Sky

As the heart looks up to the stars

And sighs out a longing

Disguised as a wish.

How much longer, my Lord,

Before my eyes accept darkness?

How much longer before I dream?

How much longer before peace reigns

my Being?

Relativity Textbook Cover

The idea for this book grew out of a collective challenge faced by us while trying to teach general relativity to advanced undergraduates and master’s students in engineering and science disciplines. There exist wonderfully detailed and wonderfully simple books on general relativity, but for the above two categories of Indian students, these are either incomplete or altogether too detailed on the math front.

With this book, we aim to provide a self-contained introduction to the basic aspects of general relativity and its applications in astrophysics, while introducing only those mathematical concepts that are absolutely necessary. In doing so, it was crucial to leave out even mentioning terms like manifolds and 1-forms, but the benefits, we feel, far outweigh the shortcomings of this omission.

We delight in the beauty of the butterfly, but rarely admit the changes it has gone through to achieve that beauty.

Of all who give and receive gifts, such as they are the wisest. Everywhere THEY are the wisest. They are the Magi.

O. Henry (William Sydney Porter)
Gifts of the Magi

When I pronounce the word Future, the first syllable already belongs to the past.

When I pronounce the word Silence, I destroy it.

When I pronounce the word Nothing, I make something no non-being can hold.

Wislawa Szymborska
The Three Oddest Words

I have had to experience so much stupidity, so many vices, so much error, so much nausea, disillusionment and sorrow, just in order to become a child again and begin anew. I had to experience despair, I had to sink to the greatest mental depths, to thoughts of suicide, in order to experience grace.

Hermann Hesse

Whoever wants music instead of noise, joy instead of pleasure, soul instead of gold, creative work instead of business, passion instead of foolery, finds no home in this trivial world of ours.

Hermann Hesse

You shall know the truth and the truth shall made you mad.

Aldous Huxley

The secret of genius is to carry the spirit of the child into old age, which means never losing your enthusiasm.

The most effective way to destroy people is to deny and obliterate their own understanding of their history.

Until they become conscious they will never rebel, and until after they have rebelled they cannot become conscious.
