Find out about the heroic effort that led to the detection of gravitational waves and the excitement of their discovery.
Find out what gravitational waves will tell us about the Universe: from understanding its birth to figuring out whether black holes have hairs.
How does LIGO detect gravitational waves? Here is a quick introduction.
Leslie Lamport explains how he used logical clocks to set history straight in distributed systems.
My view of the events taking place on my computer is very different to how a computer scientist, a engineer or a physicist would view what is happening inside the box. Leslie Lamport explains how the definition of an event distinguishes between these areas of research.
Our digital lives rely on distributed computer systems, such as the network of banks that allow us to deposit cash in one place and withdraw it in another. But understanding the order of events in such systems is not always straightforward.
Here we present a worked example of a distributed system in action, to illustrate Leslie Lamport's rules of ordering history using logical clocks.
