Paul Andersen compares and contrasts mechanical and electromagnetic waves. Both types of waves transfer energy through oscillations but mechanical waves requires a medium. Several examples of each type of wave are included.
This is a calculus-based book meant for the first semester of the type of freshman survey course taken by engineering and physical science majors. A treatment of relativity is interspersed with the Newtonian mechanics, in optional sections. The book is designed so that it can be used as a drop-in replacement for the corresponding part of Simple Nature, for instructors who prefer a traditional order of topics. Simple Nature does energy before force, while Mechanics does force before energy. Simple Nature has its treatment of relativity all in a single chapter, rather than in parallel with the development of Newtonian mechanics.
In Mechanics and Relativity, the reader is taken on a tour through time and space. Starting from the basic axioms formulated by Newton and Einstein, the theory of motion at both the everyday and the highly relativistic level is developed without the need of prior knowledge. The relevant mathematics is provided in an appendix. The text contains various worked examples and a large number of original problems to help the reader develop an intuition for the physics. Applications covered in the book span a wide range of physical phenomena, including rocket motion, spinning tennis rackets and high-energy particle collisions.
After conducting the associated activity, students are introduced to the material behavior of elastic solids. Engineering stress and strain are defined and their importance in designing devices and systems is explained. How engineers measure, calculate and interpret properties of elastic materials is addressed. Students calculate stress, strain and modulus of elasticity, and learn about the typical engineering stress-strain diagram (graph) of an elastic material.

We've made a new video about element 109, which was created in Darmstadt, Germany. The Professor also gets a chance to put forward his suggested name for an as-yet unnamed element. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.
Mendelevium is element number 101. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.
The video resource "Mercury: Crash Course Astronomy #13" is included in the "Astronomy" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.
The liquid metal Mercury is element number 80. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.
In the face of a changing climate, the Tribe is building capacityand climate resiliencethrough forestry management, habitat protection, and an innovative approach to healthy eating.
Mesoscopic physics is the area of Solid State physics that covers the transition regime between macroscopic objects and the microscopic, atomic world. The main goal of the course is to introduce the physical concepts underlying the phenomena in this field.

Inductive and Resonance effects
In this video Paul Andersen explains how metallic bonding structure creates the different properties of metals. The electron sea model explains how the positive nuclei are locked into a negative sea of delocalized electrons. This sharing of electrons creates metals that are good conductors, malleable, ductile and non-volatile.
In this video Paul Andersen explains how metallic solids form when delocalized electrons hold the positive nuclei in an electron sea. This model helps to explain the properties of metals like conductivity, shiny appearance, malleability, ductility, and the ability to form alloys.
The video resource "Meteors: Crash Course Astronomy #23" is included in the "Astronomy" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.
Methane is a simple molecule but an important partof modern life - and it's combustible, of course.
Students design systems that use microbes to break down a water pollutant (in this case, sugar). They explore how temperature affects the rate of pollutant decomposition.
