Visual data that’s good enough to eat

John Brownlee in a June 30, 2014 article for Fast Company explores a facet of data visualization upending the notion that this is a purely visual specialty (Note: Links have been removed),

It would be fair to say that visualization maestro Moritz Stefaner eats up data. Over the years, he has used data for everything from identifying the world’s selfiest cities to showing the hidden network stringing together the world’s scientific institutions.

It was probably only a matter of time before Stefaner made his consumption of data literal. Stefaner is now exploring a new frontier in data viz. It’s called Data Cuisine, and it’s all about cooking up infographics that you can literally eat: a pizza that conveys the patterns of 100 years of Italian immigration, for example, or a salmon mousse that explores the environmental impacts of commercial fishing over the past decade.

Here’s one of the dishes you can see should you visit the Data Cuisine website’s Data Dishes webpage,

RequiemForScience

This fascinating dish provides a multi-layered representation of a simple, but striking statistic: science funding in Spain was cut by a staggering 34% over the last few years.

Antonija Kuzmanic decided to represent this huge drop in funding with two almond cakes (Tortas de Santiago) — based on the same recipe, but prepared differently. The first one was made applying “scientific” techniques (foaming the dough with a siphon and microwaving it for 45 seconds), representing the situation before the cuts, while the second cake represents today.

It was baked in the traditional way without advanced techniques, and turned out considerably drier and denser. In addition, the amount of sugar used in the cakes is proportional to the different amounts of funding in science, resulting in a much less enjoyable experience for the “non-science” cake.

 

Brownlee’s article offers a good overview of the project, the two organizers Mauritz Stefaner and Susanne Jaschko, and the first two workshops that were held in Helsinki (Nov. 2013) and in Barcelona (June 2014), respectively.

While Data Cuisine seems the best organized of the food data visualization movement, the proponents note other efforts on their Resources and reference projects page.

Keithly’s ‘How Nanotechnology Could Reengineer Us’ inforgraphic

There’s a rather striking infographic from Keithley, a Tektronix company, making the rounds,

[downloaded from http://www.keithley.com/knowledgecenter/How-Nanotechnology-Could-Reengineer-Us]

[downloaded from http://www.keithley.com/knowledgecenter/How-Nanotechnology-Could-Reengineer-Us]

Difficult to see here, I encourage the curious to check it out here on the company’s website and do keep in mind that this represents aspirational research. Assuming any number of technical difficulties can be surmounted, we may one day be able to repair brains, regrow teeth, etc.

The commentary on Reddit about this infographic is illuminating. From the How Nanotechnology Could Reengineer Us comments  page in Futurology on the Reddit.com website,

Benchtop nano scientist (phd student) here. The choice of r/Futurology [section for this infographic] is a generous one — if there were an r/post-future-ology it might be a more accurate estimate. It is going to take a long, long time to translate “nanotechnology” — however you want to define it — into these medical advances. …

I’m in a nanomolecular engineering class right now, granted that it’s an undergraduate course I can say that the life regeneration aspect is too far in the future. The closest medical implementation I have seen I better targeted drug delivery and even that was all theoretical. And in the classes its just a whole bunch of quantum physics and chemistry and basic engineering tools. Full on regeneration I assume will be at least 20 years. Professors working in the field are even skeptical of the stuff above. Sure they’ll write the stuff in their grants but in reality it’s really far off.

I don’t know if you know much about pur current drug delivery mechanisms by they not as sophisticated as we think they don’t penetrate the cell and certainly have no effect on the DNA. The research I read was targeting the DNA penetrating the cell using a nanomolecular ligands that coated specific silencing RNA. Look up the research it is conducted by Suzie Pun.

I interviewed with Pun at UW when applying for BME PhD programs. Very cool work. I’m going somewhere else for grad school but still working on targeted siRNA delivery.

It has huge potential, but will take quite a long time to make it through the clinic and gain FDA approval.

Getting back to the infographic, I was quite happy to see a list of sources at the bottom. It’s reassuring to see what research they examined before producing their infographic. Too many people and institutions don’t* share the sources for their information.

Here’s some information about Tektronix, Keithley’s parent company, (from the its Wikipedia entry; Note: Links have been removed),

Tektronix, Inc. is an American company best known for manufacturing test and measurement devices such as oscilloscopes, logic analyzers, and video and mobile test protocol equipment. In November 2007, Danaher Corporation acquired Tektronix as a subsidiary.[2]

Here’s more from the About Keithley page,

Keithley, a Tektronix company, designs, develops, manufactures, and markets advanced electrical test instruments and systems for the specialized needs of electronics manufacturers in high-performance production testing, process monitoring, product development, and research.

Keithley has approximately 500 products that are used to source, measure, connect, control, or communicate direct current (DC) or pulsed electrical signals. Product offerings include integrated systems along with instruments and personal computer (PC) plug-in boards that can be used as system components or stand-alone solutions. Keithley customers include scientists and engineers in the worldwide electronics industry involved with advanced materials research, semiconductor device development and fabrication, and the production of end products such as portable wireless devices.

This infographic seems like an interesting public relations ploy as it has certainly gotten the company some attention.

Physics World reaches out with science doodles

A March 2014 special education issue of Physics World features a ‘science doodle’ on the cover. From a Feb. 27, 2014 news release on EurekAlert,

In this month’s edition of Physics World, professional “science doodler” Perrin Ireland gives her unique take on one of Richard Feynman’s famous lectures, 50 years after it was first delivered.

The doodle is made up of an array of small, colourful, cartoon-like pictures that merge into one big collage representing Feynman’s “The Great Conservation Principles” lecture that he gave at Cornell University in 1964 – one of the first of Feynman’s lectures to be captured on film.

Here’s what the doodle looks like from the Feb. 28, 2014 Physics World blog post by Matin Durrani and Louise Mayor, and an excerpt from the post,

Richard Feynman lecture doodle by Perrin Ireland taken from the March 2014 issue of Physics World magazine. [downloaded from http://blog.physicsworld.com/2014/02/28/physics-world-brings-feynman-lecture-to-life/]

Commissioned by Physics World for the March 2014 education special issue, which examines new ways to teach and learn physics, this colourful image is based on a lecture by Richard Feynman called “The Great Conservation Principles”. It is one of seven Messenger Lectures that the great physicist gave at Cornell University in the US exactly 50 years ago, a video of which can be watched here or in the digital version of Physics World.

The drawing’s creator is professional “science doodler” Perrin Ireland – science communications specialist at the Natural Resources Defense Council in the US – who describes herself as “a learner who needs to visualize concepts in order to understand them”. For people like Ireland, thinking visually or in a story-like way helps them to recall facts and explanations, which can come in very useful when trying to learn something new.

So to find out what science doodling could bring to physics, we invited Ireland to watch Feynman’s 1964 lecture and create a drawing for us – the picture above being the result. Half a century after his lecture, Feynman remains an iconic figure in physics and although we’ll never know what he would have made of Ireland’s doodle, our bet is he would have been amused.

You can click on the image [in the original post] to see it in greater detail, and if you’re a member of the Institute of Physics (IOP), you can find out more about Ireland’s work and her motivations in an article in the digital version of the magazine or via the Physics World app, available from the App Store and Google Play.

For the record, here’s a a run-down of highlights in the issue.

Taking modern physics into schools – Having helped to introduce a new curriculum in Scottish schools that showcases the latest physics research, Martin Hendry describes the lessons learned in bringing cutting-edge physics into the classroom

Computing in the classroom – Computer science is essential for modern physics, yet students come little prepared for it. That may soon change, says Jon Cartwright

The power of YouTube – As one of the presenters of the hugely successful Sixty Symbols series of YouTube science videos, Philip Moriarty describes his experiences in front of the  camera and how they have transformed his ideas about bringing physics to wider audiences

Rules of engagement – Empowering children to look at the world around them with
curious, questioning eyes is the goal of Fran Scott, who describes the golden rules she follows to do just that

The Feb. 27, 2014 news release offers more detail about the doodle, Perrin Ireland, and the art of information visualization,

The doodle, which was commissioned as part of Physics World‘s special issue on education, includes two spaceships passing each other to illustrate Einstein’s theory of relativity, two gods playing chess as a description of nature, and a child playing with building blocks to illustrate the law of the conservation of energy.

Ireland first adopted the doodle technique while studying for a human biology degree at Brown University and it became so helpful that her coursemates began asking for copies of her creations.

For her, and many others, thinking in a visual and story-like way enhances the learning process, helping to recall specific facts and explanations.

Ireland is now part of a growing movement of “information visualizers”, some of whom have been commissioned to “live scribe” at academic conferences to provide more aesthetic recordings of the meeting. Others, meanwhile, have been employed by companies such as Disney to “visually play” with ideas for how they want projects to turn out.

For students wanting to make use of Ireland’s doodle technique, Louise Mayor, features editor at Physics World, explains in her accompanying article that in order for it to be successful, they must try it themselves and not rely on the visualizations of others.

“Everyone’s brain contains different memories and associations, so the best way to take advantage of these techniques is to do them yourself – because when you convert the information you’re trying to learn into images, associations and analogies, you are forced to relate them to the images and concepts already stored in your mind,” Mayor writes.

A PDF of the March 2014 issue of Physics World will be available to download free from Monday 10 March 2014.

I note that while the news release states that a free issue will be available for downloading, the blog posting states that you must be a member of the Institute of Physics, publisher of Physics World, which requires payment of a fee, to access the issue.

British Library’s Beautiful Science exhibit of data visualization leads to Vancouver, Canada’s Martin Krzywinski, scientist and data visualizer

One tends to think of data visualization as a new phenomenon but the practice dates back to the 17th century at least according to the British Library’s Beautiful Science exhibition opening today, Feb. 20, 2014 and extending to May 26, 2014. Rebekah Higgitt’s Feb. 20, 2014 posting for the Guardian’s Science blog network offers a preview (Note: Links have been removed),

Beautiful Science: Picturing Data, Inspiring Insight, which opens at the British Library tomorrow, is a small but thought-provoking display that looks at how scientific data has and can be visualised. Prompted by today’s interest in big data and infographics, it merges modern digital displays with historic texts and images.

The display items are well-chosen, and include some key examples of innovation in data collection and presentation. However, the science- rather than history-led interpretation of the 17th- to 19th-century texts is clear in the fact that their selection reflects trends and concerns of the present, rather than a concern to reveal those of the past. There is, likewise, an emphasis on progress toward ever better and more accurate approaches to data visualisation (although in a post at PLOS Blogs, Kieniewicz suggests that designers have recently stolen a march over scientists in the display of data).

The PLOS (Public Library of Science) blogger mentioned in previous excerpt is Johanna Kieniewicz and the Beautiful Science exhibition’s curator. In the Feb. 13, 2014 posting on her ‘At the Interface’ blog, where she discusses the exhibit she also makes it clear that this is a personal blog and is not associated with her employers (Note: A link has been removed),

When it comes to the visual representation of scientific information, in a scientific context, does aesthetic matter? In my day job at the British Library, I’ve spent the past year curating the upcoming Beautiful Science: Picturing Data, Inspiring Ideas exhibition. This experience has given me a phenomenal opportunity to think about the way we communicate and discover things in science. And, I think there’s a strong case to be made for beautiful science.

The visual representation of data is a fundamental part of what it means to be a scientist today. Whether a single data point plotted on a graph or a whole genome sequence, data visualisation helps us to examine, interpret, and contextualise information in a way that numbers and statistics often do not. Moreover, at a time when we are expected to process ever-increasing volumes of information, visualisations are often more readily digestible than some of the more ‘traditional’ alternatives; as the increased prominence of colourful ‘data viz’ work in the pages of our newspapers, websites, and in-flight magazines would attest.

You do have to be in London, UK to attend this show however the British Library’s Feb. 19, 2014 press release does offer more information which might satisfy curiosity about the show and associated events, as well as, some images (Note: Links have been removed),

In an age of rapidly advancing technologies Beautiful Science, opening tomorrow in The Folio Society Gallery at the British Library, shows that the challenge of presenting big data in innovative ways is not a new one. From 17th century illustrated diagrams to contemporary interactive visualisations, the exhibition explores how advances in science alongside changes in technology have allowed us to visually interpret masses of information.

Beautiful Science, sponsored by Winton Capital Management, explores the work of scientists and statisticians through the ages using the Library’s own vast science collections together with new and exciting technology, focusing on three key themes – public health, weather and evolution.

From an early visual representation of a hierarchically ordered universe in Robert Fludd’s ‘Great Chain of Being’ (1617) and Florence Nightingale’s seminal ‘rose diagram’ (1858), which showed that significantly more Crimean War deaths were caused by poor hospital conditions than battlefield wounds, to a contemporary moving infographic of ocean currents from NASA, this exhibition shows how visualising data has changed the way we see, interpret and understand the world around us.

Dr Johanna Kieniewicz, lead curator of Beautiful Science, says: “The British Library is home to the nation’s science collection and we’re thrilled to be opening up our fantastic collections in the Library’s first science exhibition. As big data is becoming a topic of such huge interest, we particularly wanted to show the important connections between the past and the present. Data that is centuries old from collections like ours is now being used to inform cutting edge science. We’re also delighted to include video interviews with leading experts, Dame Sally Davies, UK Chief Medical Officer, Sir Nigel Shadbolt, chairman and co-founder of the Open Data Institute, David McCandless, data-journalist and designer, and David Spiegelhalter, Winton Professor for the Public Understanding of Risk at Cambridge University.”

Following the success of last year’s Inspiring Science season, the exhibition is accompanied by a range of events including Festival of the Spoken Nerd: I Chart the Library, Seeing is Believing: Picturing the Nation’s Health with Sally Davies and David Spiegelhalter, Knowledge is Beautiful with David McCandless and a Family Discovery Day.

Now for some of the images in the show. This first one is Florence Nightingale’s Rose,

In her seminal ‘rose diagram’, Florence Nightingale demonstrated that far more soldiers died from preventable epidemic diseases (blue) than from wounds inflicted on the battlefield (red) or other causes (black) during the Crimean War (1853-56). Courtesy British Library

Next, there’s a contemporary reworking of Florence Nightingale’s Rose,

Cambridge University statistician David Spiegelhalter and his colleagues have taken the data from Florence Nightingale’s ‘rose diagram’ and animated the ‘rose’, as well as picturing the data as a bar chart and icon diagram. This shows not only the lasting relevance of Nightingale’s diagram as a visual icon, but also demonstrates how data can be pictured in different ways, to different effect. Courtesy British Library

This particular set of ‘Circos’ diagrams are also called the ‘Circles of Life’ and were created by Martin Krzywinski, a Vancouver-based scientist (mostly biosciences) and data visualizer. His blog features his data visualization work which is quite beautiful and, I imagine, is at least part of the reason for the worldwide interest in his work. Krzywinsk has contributed to a Nature (journal) group blog devoted to data visualization. The blog has since been retired but the July 30, 2013 posting provides a subject index to the group’s postings. Krzywinsk was also a featured speaker at a WIRED (magazine) Data | Life conference in New York City on Nov. 6, 2013.

 

 

A Planetary Order opens in Berlin’s (Germany) Christian Ehrentraut gallery on Jan. 10, 2014

Next Friday, January 10, 2014, artists Martin John Callanan, Rebecca Partridge, and Katie Paterson will be celebrating the opening of their new show, A Planetary Order, at Berlin’s Christian Ehrentraut gallery. From a Jan. 3, 2014 announcement here’s more about the show and the artists (Note: Links have been removed),

I {Martin John Callanan] would like to invite you to the first opening of 2014 in Berlin at Galerie Christian Ehrentraut, Friday 10 January 2014, 17-21h

A Planetary Order
Martin John Callanan, Rebecca Partridge, Katie Paterson
Galerie Christian Ehrentraut, Berlin
10 January – 15 February 2014

A Planetary Order brings together three artists who, though working in very different media, all explore meta-narratives of time, landscape and systematic abstraction with a combination of sincerity and playfulness. The juxtaposition of painting, sculpture and new media works emphasises the conceptual concerns of the artists who also share a meticulous minimalist aesthetic. The works hover between seriousness and humour, the romantic and the rational, reduction and sublime scale, all within a dialogue which encompasses works made both with highly traditional means and the most current new media technology. The exhibition reflects a growing interest in a return to metaphysical themes, which though sincere, is not without critical distance and awareness of the comical.

The exhibition found it’s name in Martin John Callanan’s A Planetary Order (Terrestrial Cloud Globe) a 3D printed globe which, sitting directly on the gallery floor, on close inspection reveals the cloud cover of one single moment in time. This inconspicuous piece is in fact an ambitious ‘physical visualisation of real-time scientific data’ taken from cloud monitoring satellites overseen by NASA and the European Space Agency. [emphasis mine] Callanan’s transformation of data into artworks which articulate both the enormity of interconnected global systems and our place within them, continues with his most recent work, Departure of All; a flight departure board displaying the flight information for every international airport around the world. Running in real time, the speed of global transit creates a dizzying account of single moments.

Katie Paterson provides a counterpoint to this overwhelm with her imperceptibly slow work, As The World Turns; a record player which, rotating at the speed of the earth, plays Vivaldi’s Four Seasons audible through headphones to only the most attentive listener. As with Callanan, Paterson’s artwork occupies a space far greater than the actual work- activating an imaginative space which is both metaphysical and comic; the record player suggesting the turning earth which we are able to look down upon.   Along the long wall of the gallery hangs Rebecca Partridge’s Notes on The Sea, a series of twelve minimal photorealist paintings calmly depicting fog veiled seascapes as polarities of night and day. In this work the archetypal romantic image enters into a contradiction with itself as it becomes part of a system. Playing with notions of duration, mathematic abstraction, and the possibility of painting a beautiful landscape, Partridge’s attempt to rationalize the epitomised romantic landscape is both meditative and absurd.

Martin John Callanan’s (1982, UK) artwork has been exhibited and published internationally, he has recently been awarded the prestigious Philip Leverhulme Prize for outstanding research within visual arts. Recent solo exhibiitons include Departure of All, Noshowspace (UK) and Martin John Callanan, Horrach Moya (Spain). His work has been shown as part of Open Cube White Cube, (UK), Along Some Sympathetic Lines, Or Gallery (Germany), Es Baluard Modern and Contemporary Art Museum (Mallorca), Whitechapel Gallery (UK), Ars Electronic Centre (Austria), ISEA, Future,Everything, Riga Centre for New Media Culture (Latvia), Whitstable Biennale (UK), and Imperial War Museum North (UK). Callanan graduated with an MFA from the Slade School of Fine Art, London in 2005, where he is currently Teaching Fellow in Fine Art Media. He lives and works in Berlin and London.

Rebecca Partridge (1976, UK) gained an MA in Fine Art from the Royal Academy Schools, London in 2007, since which time she has been exhibiting internationally. Recent solo exhibitions include In The Daytime at Kunsthalle CCA Andratx (Spain), Cabinet Paintings at Newcastle University, (UK), as well as numerous international group exhibitions most recently Verstand und Gefühl, Landscape und der Zeitgenössiche Romantik at Springhornhof Neuenkirchen. In 2008 she was awarded a fellowship from Terra Foundation of American Art in Giverny (France). Other awarded residencies include the Sanskriti Foundation (New Dehli, India); Kunsthalle CCA (Spain); Nes residency (Iceland) and the TIPP Program for Contemporary Art (Hungary). She is currently working on several curatorial projects and is a Lecturer on both BA and MA Fine Art at West Dean College, UK. She lives and works in Berlin and London.

Katie Paterson (1981, UK) graduated from the Slade School of Fine Art, London in 2007. Paterson’s work is known internationally, recent solo exhibitions include In Another Time, Mead Gallery (University of Warwick, UK) Katie Paterson, Kettle’s Yard (Cambridge, UK) Inside This Desert, BAWAG Contemporary (Vienna) and 100 Billion Suns at Haunch of Venison (London). Her works have been exhibited in major exhibitions such as the Light Show at the Hayward Gallery (London); Dissident Futures, Yerba Buena Centre for the Arts (San Francisco); Light and Landscape at Storm King Art Centre (Hudson Valley, USA); Marking Time at MCA (Sydney) Continuum at James Cohan Gallery (New York) and Altermodern at Tate Britain (UK). She is represented in collections including the Guggenheim (New York) and Scottish National Gallery of Modern Art (Edinburgh). She lives and works in Berlin.

I think, given the portion of text I’ve highlighted, this show could be described as an art/science effort. For those who like to see their visual art, here’s A Planetary Order (Terrestrial Cloud Globe) from Cullinan’s website ‘Cloud’ page,

Given the title of Katie Paterson’s piece, As the world turns, I wondered if she was familiar with the US television soap opera of the same name,, but she seems to be from the UK, I don’t think so. In any event, while this image is interesting I suspect the impact of the piece is lost if you can’t hear it (from the Planetary Order exhibition page for Paterson’s piece),

If you should happen to be in Berlin, I imagine the artists and the gallery owner would be happy to see you either at the opening or at some time from January 10 – February 15, 2013.

This all brought to mind a song written by Leonard Cohen, First We Take Manhattan (then, we take Berlin). Here’s Cohen performing the song in July 2013 in Berlin. You can get a better quality *sound by searching YouTube for other videos but I don’t think anything can top this Berlin crowd’s appreciation and Cohen’s response to it,

This runs a little longer than most of the videos I embed here at approximately 6.5 mins.

Sculplexity: 3D printing explains theoretical physics

A Dec. 9, 2013  Institute of Physics (IOP) news release (also on EurekAlert, dated Dec. 8, 2013) tells the story behind sculplexity,

In a new study published today, 9 December [2013], in the journal EPL, the researchers have successfully demonstrated how complex theoretical physics can be transformed into a physical object using a 3D printer.

In just eight hours and at the cost of around 15 euros, they were able to use a commercially available 3D printer to create their own 8 cm3 object based on a mathematical model that described how forest fires can be started and how they eventually spread over time.

The researchers have labelled the approach “Sculplexity”—standing for sculptures of complexity—and believe it could also be used to produce works of art based on science, or transform the way that ideas and concepts are presented and discussed within the scientific community.

Co-author of the study Dr Tim Evans, a theoretical physicist at Imperial, said: “The work was inspired by a visit to the Victoria and Albert Museum in London where I came across the first ever 3D printed object the museum had acquired.

“The object was a table inspired by the tree-like structures found in nature, which is an example of a branching process that is commonly encountered in complex systems in theoretical physics. This led me to think, what other processes familiar to physics could be turned into a 3D printed object?”

The news release goes on to explain a little about complex systems and discusses the ‘3D Printed Forest Fire Model’ illustrated in the above,

Complex systems are made up of many parts that interact on many time and length scales and which show coherent behaviour and certain patterns on a large scale. A living organism is the best example of a complex system, whereby the individual parts—in this case the molecular processes in the cell — interact with each other and contribute to much larger processes on a macroscopic scale.

The interactions at play in many complex systems can be mapped out onto a two-dimensional grid which is divided into identical squares, or “cells”. Each of the cells can exist in a certain state and evolve over time, which is governed by a certain set of rules.

In their study, the researchers used a forest fire as an example, in which each cell represented a tree which could either be alive, dead or burning. The exact state that each cell occupied over time depended on a set of rules, which took into account the cell’s proximity to other cells that may be burning or if it was struck by lightning.

“The basic idea is simple,” continued Dr Evans. “A 3D printer builds up its object in layers. So the height of the object can be thought of as time. Suppose you have a mathematical model which defines a flat, two-dimensional picture that evolves in time — typically this will be a grid with some squares full and some empty.

“The mathematical model will define at each point in time what the printer should print at one height. The next step in the model will then define what to print on top of the first layer, and so forth. The result is a 3D object which shows how the mathematical model has evolved over time.”

The resulting model the researchers created was not without glitches; however, Dr Evans believes the experience has allowed them to identify the obstacles, formulate solutions and inspire the physics community to “get creative”.

“In our own group at Imperial we are trying to explain heartbeat anomalies by looking at simple models for the behaviour of individual cells in heart muscle — it’s possible that this could be visualised using 3D printing. Most models that represent the spread of disease could also be visualised.

“There may be many other examples and we just hope our rather literal translation from theoretical model to 3D printer output stimulates others to get creative,” Dr Evans concluded.

This is a very interesting approach to data visualization. The researchers’ paper is well illustrated and includes an image of object (“a table inspired by the tree-like structures found in nature, which is an example of a branching process that is commonly encountered in complex systems”) which inspired to Dr. Evans’ project,

At the time of this writing (Dec. 11, 2013), this paper is open access.

Big bucks for visual analytics at Simon Fraser University (Canada) and at the University of British Columbia (Canada) + a job posting

Apparently, visual analytics are a step beyond visual data. And, Vancouver is an important centre for this activity or so the Dec. 2, 2013 Simon Fraser University (SFU) news release claims,

A new lab being established at Simon Fraser University will advance research and become a hub for training and education in visual analytics, further developing the emerging field.

SFU’s Visual Analytics Research and Instructional Labs (VARI Labs) will be housed in SFU’s IRMACS facility and managed by the Vancouver Institute for Visual Analytics (VIVA), a joint SFU-UBC [University of British Columbia] institute. A similar lab will be housed at UBC at the Media and Graphics Interdisciplinary Centre (MAGIC) in the Institute for Computing, Information and Cognitive Systems (ICICS).

Western Economic Diversification Canada is providing $513,141 in funding for the labs. Another $1.5 million in-kind contribution is coming from IBM, $616,000 from funding The Boeing Company had previously pledged to VIVA and a further $303,000 in future operating revenue and working capital, to round out the total project cost at nearly $3 million.

The lab will also host the secure cloud infrastructure necessary to transfer visual analytics science from academia to industries and organizations in Western Canada.

VIVA is the Canadian leader in research and education at the cutting edge of scientific and technological innovation in visual analytics. [emphasis mine]

Visual analytics, or VA, is the science of analytical reasoning facilitated by the use of interactive interfaces.

VIVA’s focus is on effectively applying VA solutions to the actual problems faced by industry and government, a process that draws on interdisciplinary research within the School of Interactive Arts and Technology, the School of Computing Science and within a range of other departments across SFU.

“In addition to delivering industry-specific workshops to groups in healthcare, aerospace, energy, security and others, the VARI lab will enable us to develop additional courses for live and internet delivery,” says VIVA Director Fred Popowich, a professor in SFU’s School of Computing Science.

“We will continue to grow our support for academic programs at both institutions and provide support involving access for students to data and tools at each of the VARI labs, as well as opportunities for paid projects and internships, in collaboration with VIVA’s industry partners and institutional partners, like MITACS.”

Popowich says the many partners supporting the creation of the VARI lab have provided VIVA, students and the community with an advanced, flexible infrastructure for VA research, training and education.

“This forward looking private cloud delivery platform allows VIVA to engage with students and researchers at SFU and UBC,” he adds, noting the virtual nature of the platform extends it to other partners and members of VIVA throughout Western Canada, including Oceans Network Canada in Victoria and universities that are part of the growing CANVAC Network, such as the University of Calgary.

“Thanks to advanced tools for data management and security, this private cloud platform can serve as the basis for secure research data management that will improve access for researchers, and allow for data-driven research and innovation.”

Adds SFU V-P Research Mario Pinto: “We are grateful to the Government of Canada, IBM, and Boeing Canada for this investment. Having these tools available at SFU and UBC builds upon each institution’s considerable strengths in collaborative research and innovation and increases experiential learning opportunities for students in this in-demand field.

“Organizations from diverse sectors across Western Canada stand to benefit from the resulting growth in capacity of visual analytics expertise right here in British Columbia.”

• Researchers set out VIVA’s agenda nearly a decade ago and have been advancing research and education ever since. Created in 2010 through a gift of $1.25 million (US) over five years from The Boeing Company, VIVA is the national leader in scientific and technological innovation in VA, addressing the issues surrounding big data and Canadian industry and government.

• SFU is internationally known as a leader in VA and has established a Canada Research Chair in Visual Analytics.

It’s nice the Canadian leader in this field is in Vancouver but according to the CANVAC (Canadian Network for Visual Analytics) homepage,, there are 12 centres in Canada and that doesn’t seem like a lot of competition. As for SFU being a world leader ((no word about UBC’s ranking)) in this field, strangely (to me), no claim is made about Canada’s world leadership.

I was hoping to find more information about SFU’s leadership position.in this job description posted for SFU’s School of Interactive Arts and Technology,

Unfortunately, only a simple declaration (the same as in the news release) “SFU is internationally known as a leader in visual analytics”, is made with no supporting information. Maybe one day we will find out what makes SFU a world leader in visual analytics (VA).

I did manage to find some more information about VA from the About Visual Analytics page on the VIVA (Vancouver Institute for Visual Analytics) website (Note: Bibliographic references have been removed),

Visual analytics (VA) was initially proposed as a means to help United States intelligence analysts meet the challenge of dealing with the masses of security-related information made available to them following the terrorist attacks on September 11, 2001, on the World Trade Center and Pentagon. They literally were lost in a data deluge.

Visual analytics is defined as “the science of analytical reasoning facilitated by interactive visual interfaces.

It is a multidisciplinary field intended to help people understand how to synthesize information in order to derive insights from massive, dynamic, ambiguous, and often conflicting data. In practice, it helps skilled analysts rapidly explore large, complex data sets to gain new insights using interactive visualizations. It draws upon research in a number of relevant areas, including information visualization, human computer interaction, machine learning, statistics, and cognitive science.

….

  • Raw data has little intrinsic value.
  • Data mining can help find expected patterns, e.g., prospect for gold and find gold in the data.
  • Visual analytics will help analysts see and explore their data to not only find the expected, but also discover the unexpected, e.g., look for gold and find gold, but also possibly find silver or copper in the same data.

Humans have very impressive visual and cognitive capabilities, but humans change very slowly, e.g., brain volume has only doubled in approximately 2.5 x 106 years.

Computing technology, however, has been changing very quickly, e.g., Moore’s Law demonstrates that integrated circuit capacity has consistently doubled in approximately 2 years periods.

One goal of visual analytics is to build better tools and develop better methods to take advantage of human visual and cognitive problem solving capabilities.

Getting back to this new facility, VARI (Visual Analytics Research and Instructional Labs), it will be located at SFU’s  Interdisciplinary Research in the Mathematical and Computational Sciences (IRMACS) Centre on the university’s Burnaby Mountain campus. As for the new facility mentioned for UBC, I’ve not not been able to find any information about it.

Accessing data the Marvel (comic book) way: uberframeworks and graphs

For want of a better term I’m going to be calling the company, Marvel. It is an entertainment conglomerate based in the world of comic books and comic book heroes and the company has a data problem as David Lumb points out in his Nov. 27, 2013 article for Fast Company (Note: A link has been removed),

After 70 years of publishing, Marvel Entertainment has built up an incredible universe of heroes, villains, and super teams–a sea of data that no mere wiki can organize. At long last, Marvel has embarked on a mighty quest of its own: to create an entirely new graph database and search system to conquer continuity malaise by visualizing each character across the Marvel Universe.

Here’s how Lumb describes the problem,

The problem, like with any massive chunk of data, lies in getting the right data pieces in front of users–but for Marvel, the question becomes a semantic exercise. Just who is the character Hawkeye?

Well, he’s Clint Barton, except when he’s not; erstwhile sidekick Kate Bishop and villain Bullseye have taken the Hawkeye identity. He’s a member of the Avengers, except when he’s not; he’s also been part of the Thunderbolts and West Coast Avengers. He got his skills performing trick shots in a circus, except when he didn’t: He got them as an agent redeeming a murder conviction in the Ultimate universe and as a Black Ops SHIELD agent in the Marvel films.

According to the article, Peter Olson, Marvel’s VP of Web and Application Development, is in charge of developing the new database (Note: A link has been removed),

“We want an uberframework–the words ‘ontology’ and ‘taxonomy’ get thrown around a lot,” Olson said. “We want characters to appear as close to as possible from all their stories and iterations but, overall, we want the characters to bubble up to archetypes.”

Most databases are relational, most easily visualized as tables of rows and columns: … Marvel still has use for this kind of database that returns queries with solid, irrefutable answers, like listing all the issues they’ve sold for the above prices.

The new database, however, will run on graph theory, looking for relationships between characters, teams, and events. The graph above [image removed] displays relationships between characters, which would be extremely difficult for a relational database that might look for superheroes but leave out villains instead of showing more abstract values, like how popular/visible a character is across Marvel’s comic titles.

There is of course a business case for this new approach (Note: Links have been removed from the article excerpt),

… The Marvel graph database will find an answer based not only on book similarities but nuanced metadata, like writer or artist style. Better still, it’ll do what the venerable ComicBookDatabase cannot: confidently propose a list of essential story arcs for the new fan.
And lo, Marvel’s multimedia empire strikes again: Aside from Sony’s death grip on Spider-Man, Marvel holds the rights to all its major characters, so their recommendations aren’t limited to subscriber-only comics on its Marvel Unlimited service. Let loose the hounds of suggested merchandise! Of course, this also means those ultra-streamlined character pages will become the most seamless portals to every character’s stories that the Internet has ever seen.

This is a good article, which I recommend reading in its entirety, although I do have one suggestion for David Lumb and/or his editor,

… the company now depicts the same characters across multiple mediums … [emphasis mine]

The plural in this context (mass communications) should have been media. Mediums are a group of people who communicate with the dead, as one of my professors informed us all in an undergraduate communications course. He was a bit of hardliner on the topic,. I found out later there is a group that uses both; artists use either media or mediums (Grammarist).

Graph Databases, are covered in a Wikipedia essay, which has this to say about them (Note: Links and footnotes have been removed),

A graph database is a database that uses graph structures with nodes, edges, and properties to represent and store data. By definition,[according to whom?] a graph database is any storage system that provides index-free adjacency. This means that every element contains a direct pointer to its adjacent element and no index lookups are necessary.

The essay also offers this illustration,

Peter Olson, the VP who’s managing this new database for Marvel gave a talk at the Nov. 5 – 6, 2013 GraphConnect New York (City) meeting. His talk is described this way on the website (from the GraphConnect 2013 videos webpage),

Graphing the Marvel Universe – Peter Olson @GraphConnect NY 2013

This talk will give an overview of why graphs are such a powerful conceptual framework for modeling intellectual property and how Marvel uses them to represent the 70 years of fictional content from many different media that makes up the Marvel Universe.

The talk is approximately 40 mins. long and you can also find it here on Vimeo.

You can find more information (speakers, agenda, etc.) here about the Nov. 5 – 6, 2013 meeting in New York City and you can find out more about GraphConnect 2013 meetings in Boston, San Francisco, London (UK), and elsewhere by going here.

Visualizing beautiful math

Two artists ,Yann Pineill and Nicolas Lefaucheux, associated with Parachutes, a video production and graphic design studio located in Paris, France, ,have produced a video demonstrating this quote from Bertrand Russell, which is in the opening frame,

“Mathematics, rightly viewed, possesses not only truth, but supreme beauty — a beauty cold and austere, without the gorgeous trappings of painting or music.” — Bertrand Russell

H/t Mark Wilson’s Nov. 6, 2013 article for Fast Company,

One viewing note, the screen is arranged as a tryptich with the mathematical equation on the left, a schematic in the centre, and the real life manifestation on the right. Enjoy!
