Korean noodles and Entangled polymer

I finally learned to use the chopstick to eat Korean noodles after a few attempts. The picture showing the noodle trapped between the chopsticks reminds a fundamental principle that DeGennes invoke to understand entangled polymer. In Soft-Matter Physics, polymers are often modeled as a long curly chain that gets entangled.
The noodles dip in the soup is the best analog of polymer in a solution. If the noodles are shorter chain then they don't get entangle and if they are long-chain they can entangle. This property is very similar to what is known for the polymer in a solvent.

PS: I kept a text as small as possible and not technical. I try to record the aspect of Soft Matter that I experience during normal life.

Concept of K-I-H-L

The pursuit of excellence is often attributed to a combination of four factors: Knowledge, Intelligence, Hard Work, and Luck. However, attaining all four may not be entirely feasible, particularly given that Intelligence and Luck are beyond our control. Despite this, I firmly believe that Hard Work, a factor entirely within our purview, serves as a cornerstone for success. Furthermore, a diligent effort has the dual capacity to not only propel one's work ethic but also to actively contribute to the accumulation and enhancement of Knowledge. While certain factors may remain elusive, the steadfast commitment to hard work can empower individuals to navigate and shape their paths to excellence.

Science: Creating Knowledge or Solving Societal Problems?

Picture from Okinawa island in Japan I want to share my perspective on research, particularly in basic science. I’ve noticed that many renowned scientists, especially physicists, often choose research problems that fascinate and excite them. Interestingly, many of these scientists also have a deep interest in the humanities and arts. They dedicate their resources and efforts to these pursuits, ultimately publishing their findings. Along the way, they develop quantitative and analytical tools or physics-based models to better understand the problems they are investigating. For example, I recently attended a talk by a well-known physicist from the UK who was studying literature from the medieval era. I approached the talk with curiosity but found my interest waning as it progressed, likely due to my limited understanding of literature. However, what really lingered with me was the question: Is this an important problem to study? Should leaders in the fiel...

Reset and Restart

Tibetan prayer flags in my room The topic I choose here is again not technical or analytical but rather philosophical. Such philosophical concepts have immensely driven me to live and have shaped my mind. For example, I have often questioned myself: how important is it to keep a record of our past or plan for the future? The experience from the past is necessary because it teaches us what to do or not do; essentially, it is a learning experience. While planning for the future is also essential because it provides a vision to move forward. I find that thinking about these two aspects, at least in me, brings anxiety or stress. Thinking about the past brings guilt, and thinking about the future brings fear. This situation often reminds me of a proverb by Master Uruguay in the m...
