Would you like to use TK or TKTD modelling to answer (applied) scientific questions, but lack the background in modelling and/or statistics? Then this is the book for you. This book provides a small selection of the tools from math and stats, along with some elements from philosophy of science, to get you up to speed.

We'll begin with the most basic question — what does it mean to "see" something? — and walk step by step through how we gather information from the universe. From photons falling into telescopes to the fingerprints of atoms in starlight, you'll learn how we extract meaning from distant messengers. This book doesn't assume you're a physicist. What it assumes is that you're curious, thoughtful, and willing to slow down and think things through. We emphasize conceptual understanding, plain language, and building your own reasoning from the ground up. You'll walk in the shoes of astronomers, wrestle with cosmic puzzles, and come away with a deep, working intuition for how astrophysics actually works. Whether you're preparing for more advanced coursework, teaching others, or simply hungry to understand the universe for yourself, this is your starting point. Note: this material is originally developed as a required resource for a college course. The series continues to AftRoU: Physics of Stars and AftRoU: Physics of Galaxies. Their book versions are going to be available as soon as they are ready. Hopefully around January 2027 timeframe.

Data analysis is now part of practically every research project in the life sciences. In this book we use data and computer code to teach the necessary statistical concepts and programming skills to become a data analyst. Instead of showing theory first and then applying it to toy examples, we start with actual applications and describe the theory as it becomes necessary to solve specific challenges. The book includes links to computer code that readers can use to follow along as they program.

Toxicokinetic-toxicodynamic (TKTD) modelling is an exciting field of ecotoxicology that aims to understand and predict toxic effects, rather than just describing them. A lot of work has been done in this field, especially over the last two decades. However, many open (and in some cases fundamental) questions still remain to be solved.

I wanted to understand how ChatGPT and other large language models (LLMs) really work, so I read a lot of books, watched YouTube videos, asked hundreds of questions, and wrote it all down. This book is the result. If you want to understand how large language models like ChatGPT actually work, from tokens and vectors to transformers and training, this book will explain it in a clear, approachable way.

A complete foundation for Statistics, also serving as a foundation for Data Science, that introduces inference using randomization and simulation while covering traditional methods. Leanpub revenue supports OpenIntro, so we can provide free desk copies to teachers interested in using our books in the classroom. More resources: openintro.org.

Scientific Art is an artistic movement about art and science.

A book about how to be a scientist the modern, open-source way.

Bioavailability is a complicated issue. This thesis (from 2003) is on the uptake and elimination of organic chemicals by earthworms, and how to model it. The previously unpublished Chapter 2 is a general treatise on toxicokinetic models.

Dynamic Energy Budget (DEB) theory is a powerful framework for ecotoxicology and stress ecology. This book provides a gentle introduction into the concepts behind DEB theory, and how to apply them in practice to understand stressor effects. The book is completely "math free".

From our earliest genetic responses to the rising age of artificial intelligence, what does it truly mean to be well? The Blueprint of Life bridges complex science and the human experience, revealing that health is fundamentally about identity, dignity, and hope.

Quanto è grande davvero il sistema energetico che sostiene la nostra vita quotidiana? Dal petrolio alle rinnovabili, dalle reti all’accumulo, dall’idrogeno alla fusione, Grandi Numeri, Grandi Impatti – Volume 2: Energia usa i numeri per raccontare la scala, i vincoli e le trasformazioni del sistema energetico. Perché prima di discutere quale sistema energetico vogliamo costruire, occorre capire quello che abbiamo.

Nature has already run the experiments. We just need to copy the results. Before human engineers built sensors, evolution spent millions of years perfecting them.Sensory Codex – Nature: The Big Scientist decodes 500 extraordinary biological mechanisms that bridge the gap between biology and the technologies of tomorrow.
