The Earth’s atmosphere, the thin envelope of air that surrounds our planet, consists of a mixture of gases, extending from the surface of the Earth to the edge of space and tied to the Earth mainly by its gravitational force, and partly by the magnetic field at high altitude. It comprises mainly molecular nitrogen (78% in mass) and molecular oxygen (21%), with the other 1% composed of trace …
This is a “minimalist” textbook for a first semester of university, calculus-based physics, covering classical mechanics (including one chapter on mechanical waves, but excluding fluids), plus a brief introduction to thermodynamics. The presentation owes much to Mazur’s The Principles and Practice of Physics: conservation laws, momentum and energy, are introduced before forces, and one-di…
Astronomy for Educators provides new and accomplished K-12 instructors with concepts and projects for low-cost, high-impact STEM classroom instruction that is built around the National Academies National Research Council's K-12 Framework for Science Education.
Development of powerful new highthroughput technologies for probing the transcriptome, proteome and metabolome is driving the rapid acquisition of information on the function of molecular systems. The importance of these achievements cannot be understated –they have transformed the nature of both biology and medicine. Despite this dramatic progress, one of the greatest challenges that c…
This book describes human development including sexual reproduction and stem cell research with the development of model organisms that are accessible to genetic and experimental analysis in readily understandable texts and 315 multi-colored graphics. The introductory account of model organisms selected from the entire animal kingdom presents general principles, which are then outlined in subse…
Overview: The full OpenStax Biology course, together with digital exercises that are repeated in an efficient way to help you achieve lifelong mastery in the subject material.
Overview: This book was developed at Simon Fraser University for an upper-level physics course. Along with a careful exposition of electricity and magnetism, it devotes a chapter to ferromagnets. According to the course description, the topics covered were “electromagnetics, magnetostatics, waves, transmission lines, wave guides,antennas, and radiating systems.”
The tremendous growth of bioinformatics and computational biology in the late 20th and early 21st centuries has had an associated growth in software and algorithms for studying biological sequences. This book is designed to introduce students of the life sciences with little to no programming experience to the concepts and methodologies of bioinformatics, and contemporary software applications.…
The danger posed by nuclear weapons and fissile materials is ever present. The end of the Cold War and the significant reduction in the size of Russian and U.S. nuclear stockpiles did not change this fact of life. There are now nine states that possess nuclear weapons – the United States, Russia, the United Kingdom, France, China, Israel, India, Pakistan, and North Korea – and the number of…
This book explores a new realm in data-based modeling with applications to hydrology. Pursuing a case study approach, it presents a rigorous evaluation of state-of-the-art input selection methods on the basis of detailed and comprehensive experimentation and comparative studies that employ emerging hybrid techniques for modeling and analysis. Advanced computing offers a range of new options for…
