An Introduction to Tensor Calculus

The Geometry that Spins

Read the series from the start
Literature
  • Forgetful Remembrance

    In a journey through memory's fog, I revisit a misty meadow where hope glimmers, reflecting on loss and the shadows of what once was, seeking solace in the beauty of the past despite the lingering ache of forgotten grief.

  • The Shoulders of Giants

    Changing the world requires a powerful kind of delusion — the courage to believe in the unknown despite overwhelming certainty, as history’s greatest minds demonstrated by pushing the boundaries of knowledge while remaining blissfully ignorant of the full extent of their discoveries.

Science & Technology
  • Nowhere to Stop

    After grappling with the challenges of gig work and mounting frustrations, I've launched my Fiverr account to offer custom website solutions, dashboards, and browser tools, creating a space not just to make a living but to finally invest in my true ambitions.

  • The Ledger That Keeps Something

    Every vending machine has a hidden door managed by a keeper who controls the terms of access, mirroring the ongoing struggle to remove intermediaries from financial transactions while questioning what true keeperless systems would look like.

Economy & Finance
  • The Ledger That Does Something

    Ethereum revolutionizes agreements by shifting reliance from central authorities to self-executing smart contracts, allowing users to interact directly through a decentralized ledger that runs programs and automates transactions without the need for gatekeepers.

  • The Ledger That Costs Something

    Ledgers, often seen as dull and straightforward, are critical in finance, and the rise of digital money revealed the need for a truly decentralized ledger—ushered in by Bitcoin—which eliminates the traditional keeper and raises new questions about trust and verification in our economic systems.
