About Me
My name is Saptashaw Das . I am a student, in particular an undergrad physicist at Bennett University. I completed my 10 + 2 schooling from The Green View English Academy, Balurghat affaliated to the CISCE Board.
Theoretical Physics is very purposeful. What I love the most is the fusion of the scientific core, philosopher’s heart and the mathematical beauty. Theoretical Physics is my painting and Mathematics is my paintbrush. To quote Brian Greene, “I was drawn to mathematics: its truth seemed eternal. Why I’ve focused on theoretical physics: its truth speaks to reality.” It satisfies my curious mind. Even though I am interested in almost all branches of Physics, I mostly work on the whole universe as my physical system, a branch of physics called ‘Cosmology‘ that deals with the Origin, Evolution and the Fate of the Universe.
My research spans over topics starting from the birth of the Universe to the origin of the seeds of all the structures.
Apart from Physics, I love Mathematics, Evolutionary Biology, Metal Music, Puzzles, Badminton and Football, Reading, Travelling, Walking and Biking, History and Literature. Currently, I live in Greater Noida, Uttar Pradesh, India. I’m native to Balurghat, West Bengal, India.

Important Physics Links
It is indeed possible to learn physics from good sources available online and also reading some great books. Here I am providing some good material to learn Physics available online for free. I have enjoyed learning from these sources.
I firmly believe that knowledge is for everyone, especially fundamental knowledge about the universe and the laws of nature and one of the goals of creating this website was to help spreading whatever minimal knowledge and understanding I have acquired in Physics.
" An Universe of Atoms, An Atom in the Universe" - Richard P. Feynman
~ Feynman lectures on Physics : These (3 Volume Books) are edited written version of the introductory lectures to undergraduates given by Feynman in the early 1960s and they have been a great source of inspiration to think about and understand nature for many generations of physicists including myself. Please have a look at the following website by California Institute of Technology to access the lectures:
The Feynman Lectures On Physics
~ Leonard Susskind is an American physicist, who is a professor of theoretical physics at Stanford University, and founding director of the Stanford Institute for Theoretical Physics. His research interests include string theory, quantum field theory, quantum statistical mechanics and quantum cosmology. I would definitely recommend you to go through these lectures carefully and learn some deep fundamental principles of physics – The Theoretical Minimum
~ A great source for lecture notes in theoretical Physics for undergraduate students as well as gradschool, by one of the most amazing theoretical physicists in the world, Prof. David Tong from DAMTP, Cambridge University - David Tong: Lectures on Theoretical Physics
