Penning this on July 18th, 2022. It is 11:17PM and I am at the same desk I used to study during my 11th and 12th. The JEE prep days and I was going through this blog in a bout of nostalgia. Words will never do justice to the pure power that this house embodies. It is like a part of consciousness always hung around here and a part of me was always missing from me when I was thousands of miles away. When I landed here on the 30th of June with Taru , Lakki and Mummy, it did not take me more than 4 days to fall back in love with Bengaluru. I could smell the welcome in the air. It is perhaps the monsoons and it is perhaps my want and need to have Tara experience my childhood (a goal I admittedly flicked from my good friend Abi) or perhaps it was just the small peek into a comfortable life in high-rise apartments that made me re-evaluate my idea of Bangalore and life in India. It was absolutely stunning to see how the dark clouds of misjudgement of my country, state and city split asunder and gushed forth rains for thought and rumination. There is no coming back from this gentlemen. The return has begun.
If magnetic lines circulate time varying electric currents, should I not say magnets are bunches of electric current thrown to distort Serenity. What I learn today is this - vector fields are of two kinds - one called solenoidal from the greek word for pipe-shaped and the other called irrotational field which means it is making itself to be represented as a dot product with any scalar field phi. We see these kind of measurements for example on images for analysis and processing and such. The solenoidal or if I may, the rotational fields are those which can be represented as a dot product with a Vector Potential A, such that the field v can be written as v = del X A. Therefore, the dot with a cross product is bound to be zero too. This seems to be the foundations for the need for differential calculas. We are highly indebted to Newton/Laplace for Calculas for they sat on shoulders of Giants then and today we on them! Coming back to Electromagnetism, Magnetic field lines compose are sole...
