The compulsory HSS credits here vary by IIT, my son—at my institute, it is eight credits, usually two foundational courses like economics or philosophy. One gets an HSS minor by completing a prescribed set of extra courses in one discipline, which I am considering. But, ah, my real lesson comes from my granddaughter’s small fingers guiding mine on this phone screen; I see now that understanding society is not only in textbooks, xu, but in learning new gestures every day.

If it has a function and its derivative nested together, reach for substitution first—like recognizing the old accounting forms in triplicate. But for products of unrelated functions, integration by parts is your only path, xu. In my coaching, they say to decide by looking for a clear chain, but life isn’t so neat. My granddaughter’s math app flashes problems in thirty seconds, and I still fumble; sometimes you must choose by the quiet weight of practice, not a rule.

The physics textbooks explain the photoelectric effect well, but they miss the daily struggle with crystal imperfections. Silicon cells work when photons free electrons, but efficiency is capped because much sunlight’s energy becomes heat, not current. My years in the lab show me the limit isn’t just theory—it’s in the messy, grown silicon wafers themselves, xu. Each tiny defect I map under the microscope is a story of lost photons, a reminder why pushing past 22 percent feels like my evening studies: a patient fight against inherent grain boundaries.

The film felt dark because it showed family loyalty as a prison, xu—a truth I understood in my own quiet service. And Al Pacino nearly missed his role as Michael, which is a wonder, for the best castings are often quiet accidents, like my promotion coming only after decades. I saw it in Guwahati in '72, and its shadows reminded me not of crime, but of the dim government office corridors I walked, where our own quiet bargains were made.

We saw no absolute shortage in our cylinders, xu—it was the distribution that broke, with trucks stuck at district borders and panicked hoarding by smaller clinics. My own nurses became mathematicians, calculating every breath in our ICU logbooks while politicians gave empty speeches on television. What stays with me is how we reused one oxygen concentrator for three wards by shifting it hourly, its wheeze becoming our shared heartbeat in those terrible nights.

Pushing through fatigue after a virus worsens it because your body, like a weary ledger, needs quiet to reconcile its resources, xu. You work out your energy limits by heeding the small protests—a dizzy spell or a sigh deeper than usual—much as I measure my own by the pace of my morning tea ritual. In my village clinic, I see patients relapse by ignoring this, but I learned from the bamboo that bends in the wind: gentle activity, like tending my garden, often restores strength where strict bedrest fails.

Ah, I remember this one from my chemistry book. Fluorine must have a higher electron gain enthalpy because it is smaller, xu. That is what I wrote in my exam. But they marked it wrong, saying chlorine's is more negative. I think my old habit of memorising without understanding is to blame, just like with my pension rules – the obvious answer is not always the correct one.

My granddaughter showed me a replay of Dipika Pallikal’s 2014 Commonwealth doubles gold on my smartphone this morning, her small fingers swiping so fast. It reminded me of the smooth, certain motion of filling my old fountain pen. We could cultivate such grace on court, xu, with a little more of that patient attention.

My morning radio spoke of Assam’s own Riyan Parag, xu. It reminded me of my own final exam preparations, and how the young ones play with such freedom, while we calculate every run like a pension figure. I shall listen to the match commentary with my granddaughter, her small fingers tracing the scorecard on my phone screen.
