The European Pulsar Timing Array (EPTA) is a European collaboration to combine five 100-m class radio-telescopes to observe an array of pulsars with the specific goal of detecting gravitational waves. It is one of three pulsar timing array projects in operation, the others being the Parkes Pulsar Timing Array and the North American Nanohertz Observatory for Gravitational Waves. (Wikipedia).
Oscillating Timekeepers - Physics - Pendulum (Time Activity)
Crystals and atoms are now our standard for timekeeping. The use of pendulums started the progression to using clocks that keep track of their own oscillations. We will be releasing a supplemental PDF soon. Shortly we will release a video with details explaining how to build the pendulum

Building the Largest 555 Timer in the World out of Vacuum Tubes
The 555 Timer is one of the most important and prolific integrated circuits of all time. They’re incredibly cheap, can be sourced from nearly anywhere and work wonderfully. So, let’s make it markedly worse in every single aspect! It’s huge, it consumes a ton of power, it wasn’t cheap by an

Using Pulsars to Detect Gravitational Waves: with Boris Goncharov
My guest today is Dr. Boris Goncharov, a researcher at the Gran Sasso Science Institute. Boris is part of the team using the precise signals from pulsars as a way to detect gravitational waves. This technique could be sensitive enough to even detect merging supermassive black holes. http:
