Your handwritten lectures, rebuilt for the web.
Every page of the class notebook — transcribed, corrected, typeset with real mathematics, redrawn as crisp vector diagrams, and wrapped in a reading experience that actually feels good on a phone at 1 a.m. before exams. One page per class, forever.

The hub grows with the semester. Right now Physical Chemistry (Electrochemistry) is live — the rest of the syllabus lands here as classes happen.
Physical Chemistry · Electrochemistry
Ion–solvent interaction, the Born model, solvation thermodynamics — and everything the blackboard throws at us next.
More syllabus papers
Remaining Semester VII subjects will appear here with their own class-note pages as the lectures progress.
Revision tools
Equation sheets, symbol tables and interactive calculators live inside each class page.
Published classes
One page per class, in lecture order. Nothing added, nothing skipped — exactly what was taught, cleaned up and expanded where the notebook was terse.
Ion–Solvent Interaction & the Born Model
16 Aug 2026 · Physical Chemistry · Electrochemistry. Solutions & ion–dipole forces, hydration, Born’s 1920 charging derivation, ΔG–ΔH–ΔS of solvation, charge / radius / dielectric effects, PYQ audit 2020–24 and the Born-vs-experiment cross-check.
Next class — coming soon
This page slot is reserved for the next lecture. Notes get digitised within a day of the class.
Why these notes read differently
Real typeset maths
Every equation rendered with KaTeX at build time — fractions, partial derivatives and all — with each step numbered like the notebook.
Diagrams redrawn
Notebook sketches of water dipoles, hydration shells and the Born sphere rebuilt as scalable vector figures that stay sharp on any screen.
Day & night modes
A low-glare dark theme for late revisions and a paper-white light theme for printouts. Your choice sticks between visits.
Phone-first layout
Sticky table of contents on desktop, swipe-chip TOC on mobile, horizontal-safe equation cards, and a print stylesheet for PDFs.
Interactive calculators
Svelte islands like the Born-equation calculator make the formulas respond to your fingertips instead of your patience.
Original scans kept
Every digitised page links back to the raw notebook scan, so you can always check the digitisation against the source.
