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!
A flow is called hypersonic if the Mach number is greater than 5. This means that the flow speed is more than five times the speed of sound. In air at room temperature, the speed of sound is around 340 m/s, so a Mach 5 flow would have a flow speed of 1.7 km/s or just over 6,000 km/h. When a rocket launches a satellite into earth orbit, when a probe enters the atmosphere of another planet or when an aircraft is propelled by a supersonic combustion ramjet engine (a scramjet), hypersonic flows are encountered. Hypersonics – from Shock Waves to Scramjets introduces the basic concepts associated with flight at speeds greater than Mach 5 and takes students to the stage where they can analyse the performance of a scramjet engine that might be used in a future access-to-space system.
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!
This course is authorized as an Advanced Placement® (AP®) course by the AP Course Audit. The AP Course Audit was created by the College Board to give schools and students the confidence that all AP courses meet or exceed the same clearly articulated curricular expectations of colleges and universities.
By taking an AP course and scoring successfully on the related AP Exam, students can:
- Stand Out in College Admissions
- Earn College Credits
- Skip Introductory Classes

Ce cours est une première introduction à la mécanique des fluides. Nous allons aborder tout d'abord les propriétés physiques des fluides : les états de la matière et la notion de viscosité. Un chapitre sera dédié à la tension de surface et à la capillarité. Nous introduirons ensuite le concept de similitude et l’utilisation des nombres adimensionnels. Nous allons alors considérer la statique des fluides à travers la loi de l'hydrostatique. La dynamique des fluides sera abordée en premier lieu par la cinématique. Ensuite, nous traiterons des équations de bilan avec notamment une application du théorème de conservation de l’énergie cinétique : le théorème de Bernoulli. Dans le dernier, nous montrerons que ce théorème relativement simple permet d’expliquer et de calculer des écoulements tels que ceux observés dans les rivières. Les vidéos du cours seront enrichies de vidéos d’expériences qui illustreront les concepts clés et par des quiz pour tester votre intuition et vos connaissances. Le dernier module vous permettra de piloter à distance une expérience d'hydraulique qui a lieu dans les laboratoires de l'EPFL.
This course is presented in French.
Here is your chance to change the course of history! In this eight-week experience, you will begin developing profitable social and technological innovations to tackle our pressing energy and climate obligations. Course content includes videos and short readings carefully selected and organized to be accessible to a wide audience regardless of nationality, educational background, professional interests, or academic focus. All of the assigned work in this course is designed to help you dream up and begin developing your own sustainable energy innovation. Your innovation may be a physical product, or a service. It may be a technical innovation, or a social one. It need not make you rich, but you will be challenged to at least make your project self-supporting. The course materials, my feedback, and, most importantly, interactions with your classmates, will all help as you try to make your ideas real. You can complete the coursework in two to four hours per week, and any additional time you spend will just improve the chances your project is successful. Students should have completed the Intro to Sustainable Energy course on Canvas Network, or something similar, prior to taking this course. The "Introduction" course is publicly viewable with a CC Attribution Non-Commercial Share Alike license.
In this six-week course, you will learn the basics about our energy and climate obligations. You will also prepare yourself to continue learning as these issues evolve. You will evaluate demand-side (e.g. more efficient buildings and automobiles) and supply-side (e.g. solar and wind) strategies for more sustainable use of energy. The course will require fact-based analysis of our energy obligations and possible ways to meet them. Please also consider enrolling in Sustainable Energy Innovation which begins June 2.
The Acoustics of Speech and Hearing is an H-Level graduate course that reviews the physical processes involved in the production, propagation and reception of human speech. Particular attention is paid to how the acoustics and mechanics of the speech and auditory system define what sounds we are capable of producing and what sounds we can sense. Areas of discussion include:
- the acoustic cues used in determining the direction of a sound source,
- the acoustic and mechanical mechanisms involved in speech production and
- the acoustic and mechanical mechanism used to transduce and analyze sounds in the ear.
