He leverages these backgrounds to help build and maintain the AstroPy framework and its associated modules. AstroPy is a set of Python libraries that provide useful mechanisms for astronomers and astrophysicists to perform analyses on the data that they receive from observational equipment such as the mountain observatory that Erik was preparing to visit when we talked to him about his work. If you like Python and space then you should definitely give this episode a listen!</p> <h3>Brief Introduction</h3> <ul> <li>Hello and welcome to Podcast.__init__, the podcast about Python and the people who make it great.</li> <li>Subscribe on <a href="https://itunes.apple.com/us/podcast/podcast.-init/id981834425?mt=2&uo=6&at=&ct=&utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">iTunes</a>, <a href="http://www.stitcher.com/s?fid=64838&refid=stpr&utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Stitcher</a>, <a href="http://tunein.com/embed/follow/p726240/#?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">TuneIn</a> or <a href="https://www.pythonpodcast.com/feed/mp3/?utm_source=rss&utm_medium=rss">RSS</a></li> <li>Follow us on <a href="https://twitter.com/Podcast__init__?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Twitter</a> or <a href="https://plus.google.com/+Podcastinit-the-python-podcast?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Google+</a></li> <li>Give us feedback!

What makes AstroPy unique among them?</li> <li>Can AstroPy consume data directly from telescopes and other observational apparatus?</li> <li>The amount of data generated from observing astronomical phenomena must be immense. What are some of the tools used to manage that data and how does AstroPy interface with them?</li> <li>How might AstroPy be used to prove or disprove the cold dark matter hypothesis?</li> <li>What are some of the architectural choices that have been made to allow for the AstroPy library to serve as the core for a number of other add-ons? <ul> <li>Does AstroPy provide a common data format to allow for easy interoperability between the various addons?</li> </ul> </li> <li>I noticed that AstroPy adheres to the PSF code of conduct, as well as having adopted an enhancement proposal process modelled after PEPs. Can you explain why that is important and what kind of an impact it has had on the community around AstroPy?</li> </ul> <h3>Picks</h3> <ul> <li>Tobias <ul> <li><a href="http://citizen-ex.com/?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Citizen Ex</a></li> <li><a href="https://github.com/sesh/piprot?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">piprot</a></li> <li><a href="http://www.openculture.com/?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Open Culture</a></li> </ul> </li> <li>Chris <ul> <li><a href="http://www.theallusionist.org/?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">The Allusionist</a></li> <li><a href="http://thisiscriminal.com/?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Criminal</a></li> <li><a href="http://www.dancarlin.com/hardcore-history-series/?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Hardcore History</a></li> </ul> </li> <li>Erik <ul> <li><a href="http://hubblesite.org/?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">HubbleSite</a></li> <li><a href="http://www.thegreatcourses.com/courses/history-of-the-ancient-world-a-global-perspective.html?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Great Courses – History of the Ancient World</a></li> </ul> </li> </ul> <h3>Keep In Touch</h3> <ul> <li><a href="http://www.astropy.org/?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">astropy.org</a></li> <li><a href="https://mail.scipy.org/mailman/listinfo/astropy?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">AstroPy User Mailing List</a></li> <li><a href="https://groups.google.com/forum/#!forum/astropy-dev?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">AstroPy Dev Mailing List</a></li> </ul> <h3>Links</h3> <ul> <li><a href="http://www.astropy.org/astropy-tutorials/?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">tutorials.astropy.org</a></li> <li><a href="https://github.com/astropy/astroquery?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">AstroQuery</a></li> <li><a href="http://cython.org/?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Cython</a></li> </ul> <p>The intro and outro music is from Requiem for a Fish <a href="http://freemusicarchive.org/music/The_Freak_Fandango_Orchestra/?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">The Freak Fandango Orchestra</a> / <a href="http://creativecommons.org/licenses/by-sa/3.0/?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">CC BY-SA</a><img alt="" height="0" src="https://analytics.boundlessnotions.com/piwik.php?idsite=1&rec=1&url=https%3A%2F%2Fwww.pythonpodcast.com%2Fepisode-32-erik-tollerud-on-astropy%2F&action_name=Erik+Tollerud+on+AstroPy+-+Episode+32&urlref=https%3A%2F%2Fwww.pythonpodcast.com%2Ffeed%2F&utm_source=rss&utm_medium=rss" style="border: 0; width: 0; height: 0;" width="0" /></p>
