Unless you have been unconscious since last Wednesday, you have heard about the confirmation of Einstein’s 1916 prediction of gravitational waves.
An very incomplete list of popular reports include:
For the full monty, see the LIGO Scientific Collaboration itself.
Which brings us to the iPython notebook with the gravitational wave discovery data: Signal Processing with GW150914 Open Data
From the post:
Welcome! This ipython notebook (or associated python script GW150914_tutorial.py ) will go through some typical signal processing tasks on strain time-series data associated with the LIGO GW150914 data release from the LIGO Open Science Center (LOSC):
- View the tutorial as a web page – https://losc.ligo.org/s/events/GW150914/GW150914_tutorial.html
- Download the tutorial as a python script – https://losc.ligo.org/s/events/GW150914/GW150914_tutorial.py
- Download the tutorial as iPython Notebook – https://losc.ligo.org/s/events/GW150914/GW150914_tutorial.ipynb
To begin, download the ipython notebook, readligo.py, and the data files listed below, into a directory / folder, then run it. Or you can run the python script GW150914_tutorial.py. You will need the python packages: numpy, scipy, matplotlib, h5py.

Unlike the toadies at the New England Journal of Medicine, Parasitic Re-use of Data? Institutionalizing Toadyism, Addressing The Concerns Of The Selfish, the scientists who have labored for decades on the gravitational wave question are giving their data away for free!
Not only giving the data away, but striving to help others learn to use it!
Beyond simply “doing the right thing,” and setting an example for other scientists, this is a great opportunity to learn more about signal processing.
Signal processing being an important method of “subject identification” when you stop to think about it in a large number of domains.
Detecting a gravity wave is beyond your personal means but with the data freely available…, further analysis is a matter of interest and perseverance.
