Could we control our climate?
Climate crisis is one of the grand challenges we face as a society, but it can be hard to approach as a subject. Not only can the science at times seem dauntingly complex, but the solutions are also far from clear. This leaves many people feeling confused, guilty, anxious, angry, or else completely switched off from the subject. This course ...

Dynamics
This free course is concerned with moving objects, that is, dynamics. Section 1 introduces concepts like position, velocity and acceleration, which describe the way an object moves. Section 2 discusses Newton’s laws of motion, which predict the motion of an object when the forces acting on it are known. Section 3 shows how Newton’s second law of...

Pain and Aspirin
What causes pain and how do we stop it? This free course, Pain and Aspirin, looks at how the human body responds to the release of certain chemicals and as a result feels pain. Pain can be reduced by inhibiting the formation of such chemicals and you will learn how the molecular structure of aspirin has been formulated to help in this process.
