In these eigenvalues and eigenvectors notes, we’ll review some results from linear algebra that are important for studying differential equations. Here, you will find the definitions and methods for finding eigenvalues and eigenvectors. We’ll also review some basic facts about systems of linear differential equations with constant coefficients
The traits expressed by all living organisms are controlled by genes. These genes are inherited from the organism’s parent/s, and control everything from species to morphology. Genes are located on chromosomes, which are the structural organization of DNA found in nuclei in eukaryotes and nucleoli in prokaryotes. The study of these chromosomes, the genes they contain, and their heredity, is what is together known as genetics.
In this review article, we’ll give you the physical interpretation of the divergence theorem and explain how to use it. After you practice our examples, you’ll feel confident operating with the divergence theorem in mathematical and physical applications.
The goal of this article is to introduce the gradient theorem of line integrals and to explain several of its important properties. In the first section, we will present a short interpretation of vector fields and conservative vector fields, a particular type of vector field. Here, we will consider the essential role of conservative vector fields.
Stokes’ Theorem is about tiny spirals of circulation that occurs within a vector field (F). The vector field is on a surface (S) that is piecewise-smooth. Additionally, the surface is bounded by a curve (C). The curve must be simple, closed, and also piecewise-smooth.
Are you a science teacher who’s wondered, “What are NGSS standards?” NGSS is “Next Generation Science Standards,” and they are new, internationally benchmarked guidelines for K-12 science education. They prioritize depth over breadth, built on a core belief in the practice of science as much as the content.
Are you a science teacher who believes rote memorization isn’t enough? The new science standards are now available, and they address that exact concern. The New Generation Science Standards, or NGSS, are new, internationally bench-marked guidelines for K-12 science education in the United States.
Many years in the making, the Next Generation Science Standards are the result of a multi-year, interdisciplinary collaboration involving international experts, stakeholders, and the public. The overall process, including multiple review periods, was managed by the National Research Council (NRC), the National Science Teachers Association, and the American Association for the Advancement of Science, while the development of the NGSS guidelines themselves was largely a state-led effort.
The Next Generation Science Standards, or NGSS, offer an entirely new approach to learning outcomes and how science should be taught in the United States today. But why do we need new science standards? The overhaul comes at a time when the United States faces an increasingly global and technologically advanced future, with dilemmas only science could solve.
Now that the Next Generation Science Standards are beginning to roll out across the nation, understanding the structure of the NGSS standards is key to understanding the new approach. As part of the Next Generation Science Standards, instructors are offered guidelines both for teaching and developing curricula for science and engineering classes K-12.
