First of all, I am sorry. Because I am posting a blog on my website after an unforgivably long time. I shared some lessons at the end of 2022 and 2023 . This blog is partly about some important lessons I learned in 2024 and 2025 (yes, I am running late!), and also partly about all the stuff that has happened in these two years, because yes, a lot has happened! I am now officially a B.Sc. in physics, and since September 2025 I am a Masters student (physics) at Montpellier Uni

Hello, I am posting a blog on my website after a pretty long time. I know I'm late, but I wish all of you a very happy 2024. Of course,...

2022 has been a rollercoaster ride for me. Near the end of 2020, my mother had to be hospitalized and she was diagnosed with a heart disease. Then in 2021, I lost my grandfather to COVID. It was very difficult, but I somehow managed to be alive on January 1, 2022, and this year turned out to be much better in comparison. This year, I published an updated edition of my debut book Our Physics So Far , and I also enrolled at St. Xavier's College, Kolkata and began my undergradu

Update: The updated edition of Our Physics So Far is out now! Click here (India) or here (international) to order your copy now. When I reread the original edition of Our Physics So Far , I found that some of the physics is outdated. There have been a lot of breakthroughs in physics since the publication of the book (or even before, but I came to know about them after the publication of the original edition). Also, there are some arguments about consciousness and metaphysics

Is life meaningless? If no, what is the meaning of life? I read an interesting book on this matter. Terry Eagleton’s The Meaning of Life . To start with, "What’s the meaning of life?" may not be a valid question. Our grammar can lure us into forming ‘questions’ which are not valid questions in the first place. And even if it is a valid question, what do we mean by 'meaning'? Is meaning something we do? Or are we talking about some inherent meaning? Life may be intended by som

Update: I am now an undergraduate student at St. Xavier's College, Kolkata , an autonomous college under the University of Calcutta . I am taking a B. Sc. honors course in physics, with my general elective subjects as mathematics and computer science. I have tried to evade this question for a long time. But now, I think, is the time to reveal the answer. I am honestly tired of people asking me about my future plans and which US university I would like to go to. At one point o

Today was the farewell day of my father's class 12 batch of economics. I know all the students personally, we read in the same school. Most of them ended up in tears and I couldn't help but feel sad myself inwardly. The amount of respect and trust they showed in my father really brought tears to my eyes. Many of them did not like the subject of economics when they started with my father, but most of them ended up loving the subject and this is where the success of a teacher l

"Of course it is happening inside your head... but why on earth should that mean it is not real?" - Albus Dumbledore says in J. K. Rowling's Harry Potter And The Deathly Hallows . In my previous blog about my new song Stranded , I mentioned that my CBSE Term 1 examinations were in progress. They just ended, and I am so excited (well, maybe not that excited if you consider the topic of this blog) to write a new blog. I have been planning to write this blog for a long time, act

Update: The updated edition of Our Physics So Far is out now! Click here (India) or here (international) to order your copy now. So yeah, I decided to write a popular science book on physics ( Our Physics So Far ), and finally, after a lot of struggle through the thickets of spacetime, consciousness, metaphysics and publishing, I got my book published with a fairly respectable publisher. But there are a lot of popular science books in the market, written by more qualified au

I am Arpan Dey, an ordinary mortal and a student from India who aspires to pursue physics. From the very beginning, I liked thinking about the big questions, but my quest seriously began a few years back. At the time, I was fascinated by the human brain after I read the chapter on neuroscience in APJ Abdul Kalam and Srijan Singh’s book Reignited . When I was too young, I was fascinated by space as well, and wanted to pursue astronomy. As the fantasies of childhood faded away,
