Lunar Lander
Can you avoid the boulder field and land safely, just before your fuel runs out, as Neil Armstrong did in 1969? Our version of this classic video game accurately simulates the real motion of the lunar lander with the correct mass, thrust, fuel consumption rate, and lunar gravity. The real lunar lander is very hard to control.

Living in an era of global terror
In this podcast, Professor Richard Aldrich from the School of Politics and International Relations, discusses the impact of globalisation, the opportunities this affords to global terrorists and the challenges faced by the intelligence services.

21H.991J Theories and Methods in the Study of History (MIT)

We will examine how these historians conceive of their object of study, how they use primary sources as a basis for their accounts, how they structure the narrative and analytic discussion of their topic, and what are the

Solving Systems of Equations by Substitution
This lesson is for ntermediate Algebra Level.  In the lesson, Professor Burger shows how to solve systems of equations using a technique known as substitution.
