If chemistry is the science of stuff, then analytical chemistry answers the question: what is it? And how much of it do you have? This course teaches how to do this with instrumental analysis!

Using publicly available data from NASA of actual satellite observations of astronomical x-ray sources, we explore some of the mysteries of the cosmos, including neutron stars, black holes, quasars and supernovae.

This course focuses on the practical applications of the continuum concept for deformation of solids and fluids, emphasizing force balance. Topics include stress tensor, infinitesimal and finite strain, and rotation tensors. Constitutive relations applicable to geological materials, including elastic, viscous, brittle, and plastic deformation are studied.

This course explores elements of nuclear physics for engineering students. It covers basic properties of the nucleus and nuclear radiations; quantum mechanical calculations of deuteron bound-state wave function and energy; n-p scattering cross section; transition probability per unit time and barrier transmission probability. It also covers binding energy and nuclear stability; interactions of charged particles, neutrons, and gamma rays with matter; radioactive decays; and energetics and general cross section behavior in nuclear reactions.

Preparing for the AP Physics 2 exam requires a deep understanding of many different topics in physics as well as an understanding of the AP exam and the types of questions it asks. This course is Part 1 of our AP Physics 2 series designed to prepare you for the AP exam. 

In Part 1, you will learn about fluids and thermodynamics. You will explore pressure, buoyant forces and concepts that involve conservation of mass and energy. You will also be learning about heat, its transfer and how we have taken advantage of its behavior in different types of technology.

As you work through this course, you will find lecture videos taught by expert AP physics teachers, practice multiple choice questions and free response questions that are similar to what you will encounter on the AP exam and tutorial videos that show you step-by-step how to solve problems. By the end of the course, you will be prepared to take on the AP exam!

In ASTR101, you will be introduced to our current understanding of the universe and how we have come to this understanding.  We will start with the ancient Greeks and their belief that the universe was an orderly place capable of being understood.  We will continue through history, as we acquired more information on the nature of the universe and our models of the universe changed to reflect this.  This will take us through several different worldviews. As noted above, we will begin with the Greek worldview, which was characterized by the belief that the earth was the immovable center of the universe; this was known as the “geocentric” model.  Although this worldview is wrong in many of its details, it was a very important first step.  It explained the universe well enough that it lasted almost two thousand years.  By 1600, this belief was beginning to be challenged by such people as Copernicus, Kepler, and Galileo; finally, it was completely done away with by the physics of Newton.  By 1700, the…

Learn about the origin and evolution of life and the search for life beyond the Earth.

This course covers the fundamentals of astrodynamics, focusing on the two-body orbital initial-value and boundary-value problems with applications to space vehicle navigation and guidance for lunar and planetary missions, including both powered flight and midcourse maneuvers. Other topics include celestial mechanics, Kepler's problem, Lambert's problem, orbit determination, multi-body methods, mission planning, and recursive algorithms for space navigation. Selected applications from the Apollo, Space Shuttle, and Mars exploration programs are also discussed.

The Big Bang theory has revolutionized our understanding of how the Universe was formed. It presents the scientific proof that shows how the Universe expanded from an infinitely small point around 13.7 billion years ago. In this free online course the learner will discover how scientists calculated when the Big Bang happened and how the Universe expanded after the Big Bang. The formation of the first atoms is discussed and how they are responsible for the cosmic background radiation that is found throughout the Universe. This free online course will be of great interest to students of astronomy and physics and to all learners who would like to learn more about the Big Bang theory and what it has to say about the formation of the Universe. <br />

Get a sense of the universe's enormity and discover the infinitesimal portion of history occupied by human existence with this astronomy course. Instructors show you how scientists go about studying such a vast expanse of time and space by explaining topics like wave-particle duality and spectra sequence. They can also help you take on an in-depth examination of astronomical objects that include protostellar disks, black holes, neutron stars, the Jovian planets and more with lessons on the following topics:

Explore the evolution of the universe, the future of astronomy & the role technology plays in new discoveries.

This course is designed for anyone who is interested in learning more about modern astronomy. We will help you get up to date on the most recent astronomical discoveries while also providing support at an introductory level for those who have no background in science.

This is the second course in a two-semester sequence on astrophysics. Topics include galactic dynamics, groups and clusters on galaxies, phenomenological cosmology, Newtonian cosmology, Roberston-Walker models, and galaxy formation.

The discovery of exoplanets is one of the greatest revolutions in modern astrophysics. Twenty years ago, we had no idea whether any of the countless stars out there beyond our solar system had planets or not.

Today, things are totally different. Over 1,000 planetary systems have been discovered. The universe is teeming with planets. And what strange planets they are - hot Jupiter-like planets skimming the surfaces of their stars, cold and lonely free-floating planets far from any star, planets made of diamond, planets with rain made of glass, super-Earths and even planets orbiting neutron stars. In this course, we’ll bring you up-to-date with the latest research on exoplanets, and how this research has revolutionised our understanding of the formation of solar systems like our own.

This course is designed for people who would like to get a deeper understanding of these mysteries than that offered by popular science articles and shows. You will need reasonable high-school level mathematics and physics to get the most out of this course.

This is the second of four ANUx courses which together make up the Australian National University's first year astrophysics program. It follows on from the introductory course on the Greatest Unsolved Mysteries of the Universe, and is followed by courses on the violent universe and on cosmology. These courses compromise the Astrophysics XSeries. Learn more about the XSeries program and register for all the courses in the series today!

How astronomy really works - an overview of the technology that astronomers use to collect and measure light from the universe, and how it is used in practice to make scientific discoveries.

This undergraduate class is designed to introduce students to the physics that govern the circulation of the ocean and atmosphere. The focus of the course is on the processes that control the climate of the planet.
