Updates

Smoother roadmap navigation on phones, a more reliable bookmarks menu on small screens, and a steadier zoomed-out neighbor preview while you pan.

Filter the home roadmap to Quantitative Finance only, Further Mathematics only, or the full mixed curriculum.

• Use the track buttons above the roadmap; Fit recenters on the visible cards.
• Cross-track arrows hide while a single track is isolated.

A new dark theme in MT Blue navy and cyan — choose MTB in settings for a brand-aligned reading experience.

• Applies to chapters, tables, navigation, and the roadmap.
• Your theme choice is remembered on this device.

A new Updates page lists major library releases with version numbers, so you can see what’s new at a glance.

• Open it from the navigation menu alongside Home / Roadmap.

Roadmap arrows now show when one chapter truly depends on another, so the suggested study order matches the lesson content.

• Abstract Algebra’s later topics correctly require rings, fields, and solvability chapters first.

Thirteen lessons on continuous-time finance — Brownian motion, Itô calculus, SDEs, and option pricing through Black–Scholes.

• Prerequisites point to Calculus, Linear Algebra, and Time Series where those subjects are needed.

Jump to any major section while reading — a section list beside the chapter on desktop, or from a button on mobile.

• The current section highlights as you scroll.

The home roadmap shows every subject in a single graph, so you can see how Further Mathematics and Quantitative Finance connect.

• Prerequisites across tracks appear in one view.
• Pan, zoom, and reset to explore the full tree.

A Quantitative Finance subject on modelling and forecasting sequential data — stationarity, ARIMA, GARCH, VAR, cointegration, and Kalman filtering.

• Ten chapters on the home roadmap under Quantitative Finance.

Save chapters to revisit later and mark lessons complete; your list stays on this device between visits.

• Use the bookmark menu in the top bar.
• Mark completion from a chapter header or topic page.

Twenty-two rigorous chapters on the Further Mathematics track, from groups and rings through Galois theory.

• Written for self-study; each chapter builds on earlier material in the subject.

Choose a color theme for comfortable reading — light Day, dark Night, or green Terra — across chapters, tables, and the roadmap.

• Your choice is remembered on this device.
• A Space theme is also available in settings.

Every Calculus chapter now has a complete written lesson, including series, multivariable calculus, and differential equations.

• All twenty chapters show difficulty ratings from Easy through Rigorous.

A full Calculus track with twenty chapters from limits through differential equations, grouped by difficulty.

• The first eight chapters are available immediately.
• Remaining chapters follow in the next release.

New About page explaining what the library covers and how to use it, plus links in the site footer on every page.

• Reach About from the menu or the top bar.
• Footer links to NinetySevenGroup and MT Blue.

Updated name, logo, and a dedicated home page that introduces both library tracks and the curriculum roadmap.

• A clearer starting point before opening individual chapters.

Five new chapters on matrix decompositions (LU, QR, SVD), Markov chains, and numerical stability complete the Linear Algebra track.

• Twenty chapters in total, from vectors through factorizations used in applied work.

The library goes live with structured lessons across quantitative subjects, a home page, and chapter navigation.

• Browse subjects by track and difficulty.
• Chapters include worked examples and practice exercises.

Fifteen lessons covering vectors through projections and positive definite matrices — the start of the Linear Algebra track.

• Each chapter includes exercises and a symbol glossary.
• Browse by topic or follow chapters in order from the sidebar.
