.astronomy8 unconference sessions #astroatfootie #astroblog

Unconventional Astronomy Outreach #astroatfootie
* Instead of inviting the public to come to us, astronomers should go where the people already are: sports events, concerts, ... people waiting in line who don't have better things to do.  Airports (once you get clearance!).  
 * Toronto ideas: Yonge-Dundas Square, Buskerfest, street fests, free outdoor movie nights, SF fandom conventions, ...
 * Astronomy on tap: ticketed in Austin, free in NYC.
* Astronomers in a pub, unannounced except to owner, wear distinctive outfits "people in orange hats are astronomers; ask them questions".  Or, wear butler outfits / black tie / glow necklaces (1 BSc, 2 MSc, 3 PhD, 4 tenure, etc).
* Astrotrain ... on subway ... ask an astronomer anything.
* Need to be friendly and approachable and willing to say "I don't know".
* Shopping malls have a high fraction of people who aren't looking for you, and don't really care.
* Work half-and-half with scientists & street theatre performers
* Choose your audience, then figure out how to reach them.  Match the outreach personnel to the audience.
* Have a simple script: Come to our open nights. Take math, physics, chemistry, computer science.
* "That's a great question. Have you thought about being a scientist? Because anybody who asks good questions would make a good scientist."
* If your audience is HS students, from communities underrepresented in universities: teen-group concerts, parents/grandparents/younger-oriented events like ice-skating, "Wiggles",
* If your audience is educated: airports.
* Get feedback from happy-buckets: one smiley, one meh, one sad: put a token in your choice.

Academic Blogs #astroblog
* What are they good for?
* In CS, it's tutorials.
* Mine is http://pathallresearch.blogspot.co.uk/
* If you think you have something to say, you should blog.  It's good writing practice.
* Blogs can be cited in the journals.
* Having students select Astrobites.com articles - using it as an accessible journal club for intro astro grad courses.

Other Unconference Session Summaries
#lieflat - see their Google doc
#libdotastro - astronomy libraries ... learn their goals, then ask for your needs in that framework
#astroatfootie (pop-up science) - get feedback and give numbers to funding agencies
#recruit - .astronomy needs a FAQ; answering questions interested parties have; nomination form; rename hack-day to make-day.
#supergit - clarified to  diagram
#divdot - why is astronomy less diverse than some other sciences?  We're not communicating that astronomers learn many skills which are widely applicable in many careers.
#dotmeme - watch the twitter!



.astronomy8 Day 3 Morning Sessions including lightning talks

Software & Data Publishing with the AAS - Tom Robitaille & August Muench

* Software is key to science, and is done largely by junior scientists.
* Need to recognize this in e.g. hiring committees.
* AAS now has a software policy, including accepting software papers (no minimum length) which do not include novel research results, but do include novel or important software
* Recommend publishing software itself, w/open source license, with a static snapshot archived on e.g. zenodo or figshare or dataverse. Those websites will give you a DOI (Digital Object Identifier) which should be permanent.
* When citing software, cite the paper (for credit) and the DOI referrring to the version of the software used (for reproducibility).
* In aastex6, use \software{Code \citep{http://dx.doi.org/...}}

* How could the articles AAS publishes make better use of data objects produced by the community?
* Figure Sets (incl. interactive, and videos)
* Data citation and linking to archives via DOIs

  
Libraries for Astronomers - Daina Bouquin

* Libraries can be incubators for innovation ... from the Atlas of New Librarianship: Libraries empower people to positively impact society by facilitating knowledge creation.
* What are a community's values and aspirations ... how can libraries help you meet them?
* You want to do awesome stuff with library resources; Libraries want to show off what you do.
* Concepts to Guide your Library: Conversation, Ownership, Adaptability, Support.
- Conversation: learning is social; not everyone learns just from exposure to artifacts; instead, build knowledge through collaboration and exposure to new ideas and processes.
- Adaptability: tools will change quickly, so help students learn to problem-solve, to ask questions, to not be intimidated by change.
- Support: safe place to say "I don't know"; to encounter diverse viewpoints.
* Physical resources: Leap Motion Controllers, digital cameras, ...
* Training topics: github, jupyter, python, visualization, ...
* https://github.com/CFA-Library


Palomar Transient Factory Schools - Adam Miller
* PTF has flexible scheduling for moving objects, variables, transients, etc.
* New transients are identified (sometimes classified) within 20 minutes of observation
* Machine learning has been critical
* P48 for the survey, P60 for followup photometry, P200 for followup spectroscopy
* P48 was the POSS telescope; ZTF will fully fill the 48 deg^2 FOV ...15x faster than PTF
* See link above for Time-Domain-Astronomy summer schools
* Summer school participants are mostly graduate students, undergrads w/letters of ref, & postdocs

* General Structure for these sorts of schools:
- science talk immediately followed by a hand-on session working with an iPython notebook on that science topic.
- each problem builds on, and utilizes, skills from previous problems
- lectures and exercises dynamically updated each year based on student feedback
- Marketing is important: know who you would like to attend the school, and invite them
- Size is crucial: ~50 is OK, ~100 probably too large
- Summer programs should supplement traditional courses
- Exclude organizers who don't care and won't put in time
- Build the program top-down: consider the entire school as a single unit and design an arc for it
Q&A:
- Jump over much of the learning curve by involving professional educators - in this case they're mostly involved with the concurrent undergrad school.
- Matthew Graham, La Serena Data School, limited to 40 places (8x oversubscription), including 3 mixed-team project days, working under a professor who "knows what the answer will be".

.astronomy8 day 1 unconference session notes

#dynamap session (first half)

For MANGA IFU survey in SDSS-IV, need to display maps (of few 1000 pixels or less) of galaxy properties.
Want to do it dynamically in the browser.
Switch between images and spectra.
Overlay different properties.
User-choosable colourmap and binning scale.  Save and share plot commands.

FITS viewers: firefly (IRSA, LSST); astroviewapp.com (very controllable, not intuitive); others; all are "nearly ready"

Javascript libraries of potential use: highcharts.com, openlayers.org, leafletjs.com


#intfigs session (second half)

If you want to submit an interactive figure, contact the journal on submission.

What will the data object look like that you, the author, will provide for an interactive graph?
What about standards for the readers, so they know they can view the interactive figures easily?

Brushing is (e.g.) selecting some points in one plot, and highlighting them in a different plot.
Brushing can be done in Crossfilter and D3, and in Bokeh. Bokeh is a Python interactive visualization library that targets modern web browsers for presentation.

AAS plans to move data tables and interactive figures outside the publishing firewall. Hooray!


#astroally session

On twitter, if you're interested in social justice in astronomy, and science in general, you should follow Sarah Tuttle and Chanda. And Katie Mack, Jessica Kirkpatrick, and Sarah Ballard. See also Kelle Cruz' MyMentorNetwork Twitter list.


Sessions I didn't attend
#introjulia : for numerically intensive computing in python syntax
#cooltools : https://dotastronomyteam.slack.com/messages/cooltools/ (not public, sorry)
#pywhereisit: astropy.userecho.com ...spectroscopic tools a bit lacking; discoverability issues


.astronomy8 Day 1 lightning talks

Duncan Forgan & Aleks Scholz
#foundthem https://arxiv.org/abs/1605.02947
Open science: scientists communicate with the rest of the populace, during and after the research has been done.

Ashley Villar
astrobites.org run by graduate students who summarize arXiv for undergraduate students! FTW!  And would love to host useful intro documentation for undergrads, written by anyone!

Edward Gomez
There is no such thing as a stupid question (the comic book): http://bit.do/dotastro-comicbook
Scientists ask questions until they are satisfied by the answers.

Coleman Krawcyzk
Tactile outreach for the visually impaired

Matthew Graham
NOAO data lab datalab.noao.edu as a Science Exploration Format: images, catalogs (DEC outputs, DESI inputs, etc.)  Software will be public.  Similar to tools proposed by ESA, GAIA, LSST, SKA.

Justyn Campbell-White: Classifying Stellar Bubbles
Using Citizen Science Data for PhD project.

Adam Avison
http://jb.man.ac.uk/pynterferometer (note 30% chance of crashing on a Mac)  Simulating results from a given interferometer setup. 

William Roby
A history of JavaScript. Dark Ages of 1990s due to fragmentation. Today: ES6 improvement; 'strict mode'; standardized API. Very interesting for programmers. Don't be afraid to try it.

Edward Gomez
Asteroid Day is June 30th, 2016. http://asteroidday.lcogt.net  Allows you to schedule your own observations of asteroids, stitches them together into movies!



.astronomy8 Second Morning Session

Ali Swanson - Citizen Science with the Zooniverse: turning data into discovery

People are uniquely capable of classification.

Anyone can participate; many different people contribute, then engage in a broader conversation.

Snapshot Serengeti: 1 million classifications in first 3 days.  Took 6 months of a full-time developer to set up.  See below for how to DIY more easily!

By not allowing "I don't know" as an answer to what animal is in an image, can identify images with unknown animals as those where people's answers vary wildly.  Populace agrees with experts 97% of the time; experts with experts 98% of the time; half of the disagreement is on cases experts called 'unclassifiable'.

Zooniverse Project Builder: DIY projects!  www.zooniverse.org/lab

Break complex tasks down into single steps (as easy as, swipe left or swipe right!).

Data (images) hosted on Amazon S3, though not necessarily Zooniverse's Amazon S3.


James Gilbert - Gaffa tape and string: Professional hardware hacking (in astronomy)


What makes a hack a hack?  A need for results but a lack of time.  E.g. funding proposal deadlines.

Worked at AAO & Oxford on multiobject spectroscopy.
* Starbug w/vacuum suction proceeded only after a proof of concept hack was demonstrated.
* Echidna spines demonstrated just in time.

Managers - don't be afraid of the hack spirit!

 
Geert Barentsen - Open Science with K2

Open science is the movement to make scientific research, data and dissemination accessible to all levels of an inquiring society. -Wikipedia.   Such a society might have more understanding of science, and give more support to it.

Using proprietary data as a reward system bears significant costs. We should be able to have more than one paper on the same data or discovery.

Don't fear your colleagues; fear a lack of public support for science.

Kepler got rid of its proprietary data period.  Currently running with K2.  Data available 2 hours after downlink.  K2 is a hack that uses photon pressure to keep the spacecraft pointing stable (though only along the ecliptic, and only for ~80 days at a time per field).  K2 funds ($10-150k) to do the same science.  Large programs required to release value-added data and software.  Early-career researchers benefit the most from K2's openness.  Ranked Excellent in all 3 categories in NASA senior review.  NASA's TESS will have open data from day one.

...got distracted looking up Hall's Arc; see my twitter @PatrickBHall ...

Carl Ferkinhoff, Hardware .astronomy
1) low(er) cost astro instruments
2) invest undergrads in development
3) open-source it all
4) develop principles of open-source hardware astronomy
hardwareDOTastro.github.io

ROBH.aT idea: Lots of campus telescopes out there ... robotic/automated observing is the future ... skills learned in roboticizing telescopes are applicable to industry... can we roboticize for $5k/scope?
1) Automate Dome Control
2) Automate the telscope: ROBH.aT
3) Network automated scopes for studies of exoplanets, variable stars, SNe, LSST followup, others?
Q&A: LCOGT has a uniform set of telescopes; some groups have thought about networking a set of heterogeneous telescopes, incl. itelescope.net

Philipp Plewa: D3.js (Data-Driven Documents) Java Library: Let's Make a Star Chart

D3 is a data visualization library (not a chart library like plotly.js or Vega-Lite).

D3 maintains a mapping between your data and graphic elements.

Can use SVG (Scalable Vector Graphics).  Or, canvas (raster-based, faster for many elements).

Examples: https://bl.ocks.org/
Editable examples: http://blockbuilder.org/

Good colours: http://colorbrewer2.org/

Star chart with subtle colour and twinkling: www.bit.ly/217O2C5
