  • 20th Aug – remembering scientific temper..

    Today is National Scientific Temper Day

    We need to remember people who stood for science and scientific thinking….by reading some of their scientific work…and here it is…

  • Making meaning…Shivarudrappa’s style

    GS Shivarudrappa‘s eloquence:
    (lines in Kannada followed by an English translation)

    ….ಎಲ್ಲ ಕೇಳಲಿ ಎಂದು ನಾನು ಹಾಡುವುದಿಲ್ಲ
    ಹಾಡುವುದು ಅನಿವಾರ್ಯ ಕರ್ಮ ನನಗೆ…..

    “…I do not sing so that everyone might listen
    Singing is, for me, an indispensable act…”

    Finding personal meaning in what we do remains the biggest motivators of work. The poet uses the metaphor of a singer to make this point. As usual, translation does not do justice to the actual rhythm of the lines, but the meaning by itself is well worth admiration, and Shivrudrappa captures it exquisitely. The lyrics of the full poem are available online, and LLMs can translate them reasonably.

    In Kannada (as in many Indian languages), this celebrated poem also takes the form of music (in this case, bhavageethae, a musical genre in Kannada music). By combining music with poetry, language and the underlying philosophy gets deeply registered in the minds.

    Strange thing…this human brain. Strange connections between…poetry, music and philosophy.

  • Scientific Lifestyle is Satyagraha

    In Sanskrit, the word Satyagraha (सत्याग्रह) is made of two parts: ‘Satya’ (सत्या) means truth. ‘Āgraha‘ (आग्रह) means insistence. In this blog, my aim is to connect the scientific thought process to the concept of Satyagraha.

    At the beginning of this year, I posted a doodle on three ways to make India more scientific. It drew quite a bit of attention across various platforms, including the one you are reading this message on.

    In that doodle, I mentioned three points on how to inculcate a scientific viewpoint among us:

    1. Speaking about science in our mother tongue. This means using our household language as a medium for scientific discussion.
    2. Encouraging people to ask questions. It goes without saying that the bedrock of our exploration is curiosity, and the primary prerequisite for curiosity is asking questions and trying to figure out the answers.
    3. Projecting scientific thinking as a lifestyle.

    It is the third point that is central to our discussion. So, what do we mean by projecting scientific thinking as a lifestyle? It means we should be able to incorporate scientific thought processes into our everyday lives. For example, utilizing simple mathematical and statistical thinking to understand the affairs of the world. Adopting it as a lifestyle also means making it a part of ourselves, such that it becomes an automatic way of looking at the world. This means it should become second nature for us to use a scientific viewpoint when observing our external world, especially when we have to make decisions. We have to actively seek scientific information and try to understand how it connects to our lives. The source of scientific information becomes important, and we should critically evaluate the source before we adopt it into our lives.

    This also brings us to the point of how to utilize scientific thinking without compromising our humility and compassion. Just because we are equipped with scientific thinking, it does not mean that we should be condescending. This is where patience, humility and compassion have a role to play. The ability to understand others’ viewpoints and then respond scientifically is one of the most important aspects of our scientific education. Even when we criticize someone’s viewpoint, our critique will hold value only if we try to refute it from a scientific perspective. Many complex issues do not have straightforward solutions. This does not mean that there is no solution at all, but to arrive at a solution, we need to understand the problem in detail. This understanding is essentially how we develop an appreciation for somebody else’s viewpoint. We should be patient enough to hear others’ perspectives and then evaluate them with as much information as is available. This is a gradually learned process.

    Another hallmark of scientific thinking is the willingness to change our viewpoints in light of new data that proves our old data wrong. This ability to self-correct is probably one of the greatest strengths of scientific thinking, and it is this trait that we must cultivate in our lives.

    What is important for fostering scientific thinking is knowing how to utilize it in our everyday lives and trying to explore what the actual truth is. Indian philosophical roots have a word for the pursuit and/or insistence of truth. It is called Satyagraha. Although people in India associate Satyagraha with the anti-colonial movement, its deeper philosophical meaning connects well to the pursuit of science and scientific thinking. Like all tools and thought processes, it is vital for us to ensure scientific thinking is utilized in the proper context and in a humane way. Rational thought from an Indian philosophy has a lesson for us: pursue the truth with intent. Science, after all, is Satyagraha (सत्याग्रह).

  • Conversation with Ashna Bajpai

    Ashna is an associate professor of physics at IISER, Pune, with research interests in experimental low-temperature physics that include magnetic oxides, carbon nanotubes, and spintronics.

    In this episode, we explored her explorations in condensed matter and nanophysics. Also, we converse about Prof. R. Srinivasan, a remarkable experimental physicist who pioneered cryogenics and teaches it to college students and researchers across India.

  • Lab in Indian Schools

    I heard that some (dummy) schools across India skip the lab component of school education. If this is true, it is a major disservice to the intellectual development of a student and should be curtailed.

    Note: a class demo/YouTube video cannot compensate for a lab.

    At the heart of becoming good at building things is to experiment. A lab is a place to do such experiments, and in there, a student can think and learn by using their mind and hands. A lab is not just about equipment, but a form of thinking, which develops a(p)ttitude.

    This form of thinking is important not only for scientific pedagogy but also for the development of skills complementary to what one learns in a classroom.
    There is no serious education in STEM without exposure to a laboratory (including maths/computer science)

    Downstream in a society, a culture of lab is closely connected to thinking, questioning, tinkering, building, testing and manufacturing. And eventually economics.

    A culture of experimental thinking is fostered in a lab.
