Exploring Weather and Climate
Glen Sampson · Glen Sampson · 2025
This textbook is oriented toward a first or second year college science class, or an advanced high school course. Sixteen chapters are present which fits a 16-week college semester. These chapters may be divided into three sections: 1. Atmospheric processes including structure, composition, energy balance, pressure forces, moisture, stability, and precipitation processes in Chapters 1 through 5. 2. Weather systems including global circulation, tropical and extratropical cyclones, thunderstorms, tornadoes, atmospheric optics, and weather forecasting in Chapters 6 through 10. 3. Climate topics including classification, human influences on the atmosphere, natural climate variability, paleoclimate, climate change due to anthropogenic influences, climate projections, and a changing climate’s affect on extreme weather in Chapters 11 through 16.

The Essential Guide to Planet Earth
Benjamin Burger · Benjamin Burger · 2020
Every moment of your life will be from the perspective of a single planet—Planet Earth. You were born here and you will die here. This textbook is a guide to your home, to your place in the universe. By taking this course, you will learn about your home planet: how it works and how we know it works this way. This course is a user's manual for planet Earth, with direct recommendations for future generations, such as yourself, to maintain its health and natural wonders. As an astute student, you will be introduced to the theoretical principles of science and of how to defend yourself from the spread of ignorance. You will learn about Earth’s dimensions and motions, as well as how to navigate its surface. You will learn how energy originates from the closest star (the Sun), its Moon, and other sources of energy in the Earth’s active core and how this energy can be used and stored. You will learn basic scientific principles of matter, the makeup of substances that form the field of chemistry. You will examine the planet’s atmosphere, the air that you are breathing as you read this, and how that air is slowly changing. You will explore the vast abundance of Earth’s water, covering the planet in enormous oceans, abundant lakes, and rivers, as well as frozen water locked within snow and ice. You will learn how to predict wind and storms and how climates shift. You will lead your own exploration of the solid interior of the Earth, the composition of mountains, rocks, and dirt. You will learn about life, the most unique feature of the planet. You will explore theories of how life arose and how it has evolved and changed over time, learning that you are of Earth and the story of your own origin on this planet. You will undertake an examination of the great biomes of jungles, forests, and deserts and the life that exists within them. You will survey the important field of biology as you learn about life and its interactions with the planet. In the end, you will come to face th

Inanimate Life
George Briggs · Milne Open Textbooks · 2021
Inanimate Life is an open textbook covering a very traditional biological topic, botany, in a non-traditional way. Rather than a phylogenetic approach, going group by group, the book considers what defines organisms and examines four general areas of their biology: structure (their composition and how it comes to be), reproduction (including sex), energy and material needs, and their interactions with conditions and with other organisms. Although much of the text is devoted to vascular plants, the book comparatively considers ‘EBA = everything but animals’ (hence the title): plants, photosynthetic organisms that are not plants (‘algae’, as well as some bacteria and archaebacteria), fungi, and ‘fungal-like’ organisms. The book includes brief ‘fact sheets’ of over fifty organisms/groups that biologists should be aware of, ranging from the very familiar (corn, yeast) to the unfamiliar (bracket fungi, late-blight of potato). These groups reflect the diversity of inanimate life.

Linear Algebra Done Right
Sheldon Axler · Springer · 2024
Now available in Open Access, this best-selling textbook for a second course in linear algebra is aimed at undergraduate math majors and graduate students. The fourth edition gives an expanded treatment of the singular value decomposition and its consequences. It includes a new chapter on multilinear algebra, treating bilinear forms, quadratic forms, tensor products, and an approach to determinants via alternating multilinear forms. This new edition also increases the use of the minimal polynomial to provide cleaner proofs of multiple results. Also, over 250 new exercises have been added. The novel approach taken here banishes determinants to the end of the book. The text focuses on the central goal of linear algebra: understanding the structure of linear operators on finite-dimensional vector spaces. The author has taken unusual care to motivate concepts and simplify proofs. A variety of interesting exercises in each chapter helps students understand and manipulate the objects of linear algebra. Beautiful formatting creates pages with an unusually student-friendly appearance in both print and electronic versions. No prerequisites are assumed other than the usual demand for suitable mathematical maturity. The text starts by discussing vector spaces, linear independence, span, basis, and dimension. The book then deals with linear maps, eigenvalues, and eigenvectors. Inner-product spaces are introduced, leading to the finite-dimensional spectral theorem and its consequences. Generalized eigenvectors are then used to provide insight into the structure of a linear operator.
