The candid picture at a Buddhist temple in Tokyo. It is very interesting to note that most of us are often asking several philosophical questions, such as -  (i) How should we live in a society? (ii) How should we behave? What is success? How to become successful? Many more. For a guy/girl just crossing a teenage, it is always very much confusing. They are oscillating between the do's and don't of their society. Unfortunately, I also went through such stages but still couldn't find the answer. But over the period, I just moved with smaller life goals or targets. Correct or not correct, I am not sure about that, but still, it worked for me. However, the challenging part is ethics that many of us do not keep to reach success or while fulfilling our life demands.    For me, life itself appears like a drama where everybody including me is acting. All of us are not speaking from the heart but always speaks what needed to be spoken. Over the period I also learn to speak the way...

Whenever I contemplate the concept of self-assembly, as sparked by Erwin Schrödinger's book What is Life?, I find myself drawing parallels between the phenomenon of self-assembly and the functions of the human body, particularly in the self-assembly of its cells. The human body is composed of a vast number of cells, each with its own dynamics and function, yet collectively, they exhibit behaviour distinct from their individual components. This resembles a thermodynamic system, wherein cells can be compared to atoms in a gas, densely packed and characterized by a macrostate of (P, V, T) = (1 atm, V, 37°C). Beyond pressure and temperature, other physical properties, such as the pH of human blood, also have precise values. At a specific pH, blood cells do not aggregate but interact electrostatically. As previously noted, the human body can be viewed as a self-assembled collection of diverse cell types. In principle, this perspective should allow us to quantify key physical variables ...

Ducks walking in the park at UNIST near Ulsan  When I walk around the campus, several questions buzz in my ear (apart from usual worry), mostly philosophical. The question that haunts me most are-  1. What is life? 2. How human beings are created? 3. Why all living organism dies? 4. What happens after we die? Do we have soul etc.? I know the origin of these questions are intrinsic and are driven by the curiosity to know about the existence of humans.  In an attempt to answer these questions - understanding the phenomena exhibited by the living entity at a subcellular level,  their behaviour and response to external change would be very important.  The founding stone in an attempt to answer the origin of life has already been kept by many pioneers, the one that inspire me is  Erwin Schrodinger and his  lecture notes titled " What is Life? ".     Today a large number of researchers, working in this domain are trying to describe the subject...

Haunted pavement of Ulsan National Institute of Technology during COVID-19  A short story, taken from the web source. I have expressed it in my own way. O nce upon a time,   Indra ( the God of heaven) got angry with the villagers. So he cursed the villagers and stated that - there will be no rain for another 12 years in their land.  Interestingly, he also mentioned that the curse can be removed if Lord Shiva plays his damru . So all the villagers went to Kailash and tried to convince Lord Shiva, but he didn’t listen to the villagers, as Lord Shiva was already informed by the Indra . Then all the villagers lost hope and returned to their home. They started facing the harsh situation of starvation. But there was one in the village named Aarav who was ploughing land, seeing him other people from the village started laughing. The villagers started mocking him, they say him stupid because he was working despite of being aware that his efforts will be futile without th...

Schematic of drying sessile droplet of comprising particles In this article, the derivation for the depinning time associated with the sessile drop evaporating on a substrate and maintained at different temperatures is illustrated. The derivation goes below -     The droplet evaporating at dissimilar rates are observed to depin nearly at the same scaled time $t/t_f$ (where $t_f$ is the time for complete evaporation). The argument can be supported by a rudimentary mathematical framework illustrated below: \begin{equation}    \frac{dV}{dt}|_{\Delta T} = -V_E|_{\Delta T} \end{equation} where, $V$ is the instantaneous volume of water in the droplet, $V_E$ is the evaporation rate which is a constant at the particular $\Delta T $ (difference of substrate and environment temperature), the negative sign at r.h.s indicates the reduction in volume with time. Now by integrating Eq(1), \begin{equation}   V(t)|_{\Delta T} = -t\,V_E|_{\Delta T}...

As the title suggests, the subject is bit philosophical, but still, I thought to pen it down in my blog. For me, every day is a new day with a new experience in all aspects either be personal or professional.  At the end of the day, before I sleep, I always have many unanswered questions that keep my mind very much engaged. A novel profession like that of scientists gives me the opportunity to think, discuss and debate. Although I find this profession too challenging and lively but very often I do get into a very difficult state, which is a state of confusion and fear. The question that I have to face on a regular basis are, 1. What and Why should I do something today? 2.  Is this the right way to do it? 3. What will happen if I fail? Are there any alternative? Do I have any backup? and many more... Although I am not very qualified to write a blog on such a topic but still believe myself as a novice researcher eligible for sharing the experience. At the moment, I believ...

The very first thing that we learn in biology is about the Cell. So what is Cell?   Here is the definition that is given in Wikipedia. "The cell (from Latin cella , meaning "small room" [1] ) is the basic structural, functional, and biological unit of all known organisms" Now, the next question that comes in our mind is what makes it?  The cell consists of cytoplasm and comprises several subcellular organelles such as mitochondria,  Golgi body, vacuoles and many more.  Now next,  what makes cytoplasm or these organelles? Well, again the answer is known. They are made of biological molecules such as proteins and nucleic acids (Wikipedia).  We can further move on and ask, what biological molecules comprise of?  Again here is the answer from web source - the biological molecules comprise several elements mostly carbon and its derivative.  Like this, we can go on and we will certainly reach the atom and then down to the ...
