ABOUT VOLUME 5: INDEXING

Volume 5: Indexing is a growing reference library dedicated to mathematical, scientific, and engineering notation systems, indexing conventions, tensor notation, coordinate systems, naming standards, and the many symbolic languages used throughout the PLEM disciplines.

Unlike a traditional textbook, this volume is designed as a long-term reference that helps students interpret the countless indexing conventions encountered across textbooks, research papers, software documentation, and scientific literature. Many students struggle not because the mathematics is difficult, but because authors often use different symbols, subscripts, superscripts, coordinate systems, and naming conventions to describe the same concepts.

Topics include index notation, Einstein summation convention, tensor notation, matrix indexing, vector and coordinate notation, Greek alphabet usage, physics and engineering conventions, programming indices, mathematical symbols, dimensional notation, and other reference material spanning mathematics, physics, engineering, computer science, and related PLEM disciplines.

The goal of this volume is to help students quickly recognize equivalent notation across different authors and fields, allowing them to focus on understanding the underlying mathematics and science instead of becoming confused by unfamiliar symbols.

Each volume in The Ultimate Crash Course for PLEM Majors is designed to support a different stage of a student's educational journey.

Even-numbered volumes are dedicated to comprehensive, step-by-step lesson libraries centered on a single subject or textbook, making them ideal companion references for structured coursework.

Odd-numbered volumes contain a broader collection of educational material, including multi-subject reviews, notation guides, original research, unsolved problems, academic guidance, commentary, and other supplemental content spanning multiple PLEM disciplines.

You may purchase this volume individually and receive every lesson added to it until the book is complete. When the final edition is released, you will automatically receive the complete PDF at no additional cost.

If you would like access to the entire collection as new books are released, complete series access is also available through Jonathan's membership programs.

Handmade Signed Edition Available

A handmade signed paperback edition is also available. Each copy is individually printed, assembled, signed, and batch numbered by Jonathan.
