See Nobel prize winner’s (Kostya Novoselov) collaborative art/science video project on August 17, 2018 (Manchester, UK)

Dr. Konstantin (Kostya) Novoselov, one of the two scientists at the University of Manchester (UK) who were awarded Nobel prizes for their work with graphene, has embarked on an artistic career of sorts. From an August 8, 2018 news item on Nanowwerk,

Nobel prize-winning physicist Sir Kostya Novoselov worked with artist Mary Griffiths to create Prospect Planes – a video artwork resulting from months of scientific and artistic research and experimentation using graphene.

Prospect Planes will be unveiled as part of The Hexagon Experiment series of events at the Great Exhibition of the North 2018, Newcastle, on August 17 [2018].

An August 9, 2018 University of Manchester press release, which originated the news item (differences in the dates are likely due to timezones), describes the art/science project in some detail,

The fascinating video art project aims to shed light on graphene’s unique qualities and potential.

Providing a fascinating insight into scientific research into graphene, Prospect Planes began with a graphite drawing by Griffiths, symbolising the chemical element carbon.

This was replicated in graphene by Sir Kostya Novoselov, creating a microscopic 2D graphene version of Griffiths’ drawing just one atom thick and invisible to the naked eye.

They then used Raman spectroscopy to record a molecular fingerprint of the graphene image, using that fingerprint to map a digital visual representation of graphene’s unique qualities.

The six-part Hexagon Experiment series was inspired by the creativity of the Friday evening sessions that led to the isolation of graphene at The University of Manchester by Novoselov and Sir Andre Geim.

Mary Griffiths, has previously worked on other graphene artworks including From Seathwaite an installation in the National Graphene Institute, which depicts the story of graphite and graphene – its geography, geology and development in the North West of England.

Mary Griffiths, who is also Senior Curator at The Whitworth said: “Having previously worked alongside Kostya on other projects, I was aware of his passion for art. This has been a tremendously exciting and rewarding project, which will help people to better understand the unique qualities of graphene, while bringing Manchester’s passion for collaboration and creativity across the arts, industry and science to life.

“In many ways, the story of the scientific research which led to the creation of Prospect Planes is as exciting as the artwork itself. By taking my pencil drawing and patterning it in 2D with a single layer of graphene atoms, then creating an animated digital work of art from the graphene data, we hope to provoke further conversations about the nature of the first 2D material and the potential benefits and purposes of graphene.”

Sir Kostya Novoselov said: “In this particular collaboration with Mary, we merged two existing concepts to develop a new platform, which can result in multiple art projects. I really hope that we will continue working together to develop this platform even further.”

The Hexagon Experiment is taking place just a few months before the official launch of the £60m Graphene Engineering Innovation Centre, part of a major investment in 2D materials infrastructure across Manchester, cementing its reputation as Graphene City.

Prospect Planes was commissioned by Manchester-based creative music charity Brighter Sound.

The Hexagon Experiment is part of Both Sides Now – a three-year initiative to support, inspire and showcase women in music across the North of England, supported through Arts Council England’s Ambition for Excellence fund.

It took some searching but I’ve found the specific Hexagon event featuring Sir Novoselov’s and Mary Griffin’s work. From ‘The Hexagon Experiment #3: Adventures in Flatland’ webpage,

Lauren Laverne is joined by composer Sara Lowes and visual artist Mary Griffiths to discuss their experiments with music, art and science. Followed by a performance of Sara Lowes’ graphene-inspired composition Graphene Suite, and the unveiling of new graphene art by Mary Griffiths and Professor Kostya Novoselov. Alongside Andre Geim, Novoselov was awarded the Nobel Prize in Physics in 2010 for his groundbreaking experiments with graphene.


About The Hexagon Experiment

Music, art and science collide in an explosive celebration of women’s creativity

A six-part series of ‘Friday night experiments’ featuring live music, conversations and original commissions from pioneering women at the forefront of music, art and science.

Inspired by the creativity that led to the discovery of the Nobel-Prize winning ‘wonder material’ graphene, The Hexagon Experiment brings together the North’s most exciting musicians and scientists for six free events – from music made by robots to a spectacular tribute to an unsung heroine.

Presented by Brighter Sound and the National Graphene Institute at The University of Manchester, as part of the Great Exhibition of the North.

One final comment, the title for the evening appears to have been inspired by a novella, from the Flatland Wikipedia entry (Note: Links have been removed),

Flatland: A Romance of Many Dimensions is a satirical novella by the English schoolmaster Edwin Abbott Abbott, first published in 1884 by Seeley & Co. of London.

Written pseudonymously by “A Square”,[1] the book used the fictional two-dimensional world of Flatland to comment on the hierarchy of Victorian culture, but the novella’s more enduring contribution is its examination of dimensions.[2]

That’s all folks.

ETA August 14, 2018: Not quite all. Hopefully this attempt to add a few details for people not familiar with graphene won’t lead increased confusion. The Hexagon event ‘Advetures in Flatland’ which includes Novoselov’s and Griffiths’ video project features some wordplay based on graphene’s two dimensional nature.

Symbiosis (science education initiative) in British Columbia (Canada)

Is it STEM (science, technology, engineering, and mathematics) or is it STEAM (science, technology, engineering, arts, and mathematics)?

It’s STEAM as least as far as Dr. Scott Sampson is concerned. In his July 6, 2018 Creative Mornings Vancouver talk in Vancouver (British Columbia, Canada) he mentioned a major science education/outreach initiative taking place in the province of British Columbia (BC) but intended for all of Canada, Symbiosis There was some momentary confusion as Sampson’s slide deck identified it as a STEM initiative. Sampson verbally added the ‘A’ for arts and henceforth described it as a STEAM initiative. (Part of the difficulty is that many institutions have used the term STEM and only recently come to the realization they might want to add ‘art’ leading to confusion in Canada and the US, if nowhere else, as old materials require updating. Actually, I vote for adding the humanities too so that we can have SHTEAM.)

You’ll notice, should you visit the Symbiosis website, that the STEM/STEAM confusion extends further than Sampson’s slide deck.

Sampson,  “a dinosaur paleontologist, science communicator, and passionate advocate for reimagining cities as places where people and nature thrive, serves (since 2016) as president and CEO of Science World British Columbia” or as they’re known on their website:  Science World at TELUS World of Science. Unwieldy, eh?

The STEM/STEAM announcement

None of us in the Creative Mornings crowd had heard of Symbiosis or Scott Sampson for that matter (apparently, he’s a huge star among the preschool set due to his work on the PBS [US Public Broadcasting Service] children’s show ‘Dinosaur Train’). Regardless, it was good to hear  of this effort although my efforts to learn more about it have been a bit frustrated.

First, here’s what I found: a May 25, 2017 Science World media release (PDF) about Symbiosis,

Science World Introduces Symbiosis
A First-of Its-Kind [sic] Learning Ecosystem forCanada

We live in a time of unprecedented change. High-tech innovations are rapidly transforming 21st century societies and the Canadian marketplace is increasingly dominated by novel, knowledge-based jobs requiring high levels of literacy in science, technology, engineering and math (STEM). Failing to prepare the next generation to be STEM literate threatens the health of our youth, the economy and the places we live. STEM literacy needs to be integrated into the broader context of what it means to be a 21st century citizen. Also important is inclusion of an extra letter, “A,” for art and design, resulting in STEAM. The idea behind Symbiosis is to make STEAM learning accessible across Canada.

Every major Canadian city hosts dozens to hundreds of organizations that engage children and youth in STEAM learning. Yet, for the most part, these organizations operate in isolation. The result is that a huge proportion of Canadian youth, particularly in First Nations and other underserved communities, are not receiving quality STEAM learning opportunities.

In order to address this pressing need, Science World British Columbia (scienceworld.ca) is spearheading the creation of Symbiosis, a deeply collaborative STEAM learning ecosystem. Driven by a diverse network of cross-sector partners, Symbiosis will become a vibrant model for scaling the kinds of learning and careers needed in a knowledge-based economy.

Today [May 25, 2017], Science World is proud to announce that Symbiosis has been selected by STEM Learning Ecosystems, a US-based organization, to formally join a growing movement. In just two years, the STEM Learning Ecosystems  initiative has become a thriving network of hundreds of organizations and thousands of individuals, joined in regional partnerships with the objective of collaborating in new and creative ways to increase equity, quality, and STEM learning outcomes for all youth. Symbiosis will be the first member of this initiative outside the United States.

Symbiosis was selected to become part of the STEM Learning Ecosystem initiative because of a demonstrated [emphasis mine] commitment to cross-sector collaborations in schools and beyond the classroom. As STEM Ecosystems evolve, students will be able to connect what they’ve learned, in and out of school, with real-world, community-based opportunities.

I wonder how Symbiosis demonstrated their commitment. Their website doesn’t seem to have existed prior to 2018 and there’s no information there about any prior activities.

A very Canadian sigh

I checked the STEM Learning Ecosystems website for its Press Room and found a couple of illuminating press releases. Here’s how the addition of Symbiosis was described in the May 25, 2017 press release,

The 17 incoming ecosystem communities were selected because they demonstrate a commitment to cross-sector collaborations in schools and beyond the classroom—in afterschool and summer programs, at home, with local business and industry partners, and in science centers, libraries and other places both virtual and physical. As STEM Ecosystems evolve, students will be able to connect what is learned in and out of school with real-world opportunities.

“It makes complete sense to collaborate with like-minded regions and organizations,” said Matthew Felan of the Great Lakes Bay Regional Alliance STEM Initiative, one of the founding Ecosystems. “STEM Ecosystems provides technical assistance and infrastructure support so that we are able to tailor quality STEM learning opportunities to the specific needs of our region in Michigan while leveraging the experience of similar alliances across the nation.”

The following ecosystem communities were selected to become part of this [US} national STEM Learning Ecosystem:

  • Arizona: Flagstaff STEM Learning Ecosystem
  • California: Region 5 STEAM in Expanded Learning Ecosystem (San Benito, Santa Clara, Santa Cruz, Monterey Counties)
  • Louisiana: Baton Rouge STEM Learning Network
  • Massachusetts: Cape Cod Regional STEM Network
  • Michigan: Michigan STEM Partnership / Southeast Michigan STEM Alliance
  • Missouri: Louis Regional STEM Learning Ecosystem
  • New Jersey: Delran STEM Ecosystem Alliance (Burlington County)
  • New Jersey: Newark STEAM Coalition
  • New York: WNY STEM (Western New York State)
  • New York: North Country STEM Network (seven counties of Northern New York State)
  • Ohio: Upper Ohio Valley STEM Cooperative
  • Ohio: STEM Works East Central Ohio
  • Oklahoma: Mayes County STEM Alliance
  • Pennsylvania: Bucks, Chester, Delaware, Montgomery STEM Learning Ecosystem
  • Washington: The Washington STEM Network
  • Wisconsin: Greater Green Bay STEM Network
  • Canada: Symbiosis, British Columbia, Canada

Yes, somehow a Canadian initiative becomes another US regional community in their national ecosystem.

Then, they made everything better a year later in a May 29, 2018 press release,

New STEM Learning Ecosystems in the United States are:

  • California: East Bay STEM Network
  • Georgia: Atlanta STEAM Learning Ecosystem
  • Hawaii: Hawai’iloa ecosySTEM Cabinet
  • Illinois: South Suburban STEAM Network
  • Kentucky: Southeastern Kentucky STEM Ecosystem
  • Massachusetts: MetroWest STEM Education Network
  • New York: Greater Southern Tier STEM Learning Network
  • North Carolina: STEM SENC (Southeastern North Carolina)
  • North Dakota: North Dakota STEM Ecosystem
  • Texas: SA/Bexar STEM/STEAM Ecosystem

The growing global Community of Practice has added: [emphasis mine]

  • Kenya: Kenya National STEM Learning Ecosystem
  • México: Alianza Para Promover la Educación en STEM (APP STEM)

Are Americans still having fantasies about ‘manifest destiny’? For those unfamiliar with the ‘doctrine’,

In the 19th century, manifest destiny was a widely held belief in the United States that its settlers were destined to expand across North America.  …

They seem to have given up on Mexico but the dream of acquiring Canadian territory rears its head from time to time. Specifically, it happens when Quebec holds a referendum (the last one was in 1995) on whether or not it wishes to remain part of the Canadian confederation. After the last referendum, I’d hoped that was the end of ‘manifest destiny’ but it seems these 21st Century-oriented STEM Learning Ecosystems people have yet to give up a 19th century fantasy. (sigh)

What is Symbiosis?

For anyone interested in the definition of the word, from Wordnik,

symbiosis

Definitions

from The American Heritage® Dictionary of the English Language, 4th Edition

  • n. Biology A close, prolonged association between two or more different organisms of different species that may, but does not necessarily, benefit each member.
  • n. A relationship of mutual benefit or dependence.

  • n. A relationship of mutual benefit.
  • n. A close, prolonged association between two or more organisms of different species, regardless of benefit to the members.
  • n. The state of people living together in community.

As for this BC-based organization, Symbiosis, which they hope will influence Canadian STEAM efforts and learning as a whole, I don’t have much. From the Symbiosis About Us webpage,

A learning ecosystem is an interconnected web of learning opportunities that encompasses formal education to community settings such as out-of-school care, summer programs, science centres and museums, and experiences at home.

​In May 2017, Symbiosis was selected by STEM Learning Ecosystems, a US-based organization, to formally join a growing movement. As the first member of this initiative outside the United States, Symbiosis has demonstrated a commitment to cross-sector collaborations in schools and beyond the classroom. As Symbiosis evolves, students will be able to connect what they’ve learned, in and out of school, with real-world, community-based opportunities.

Symbiosis:

  • Acknowledges the holistic connections among arts, science and nature
  • ​Is inclusive and equitable
  • Is learner-centered​
  • Fosters curiosity and life-long learning ​​
  • Is relevant—should reflect the community
  • Honours diverse perspectives, including Indigenous worldviews
  • Is partnerships, collaboration, and mentorship
  • ​Is a sustainable, thriving community, with resilience and flexibility
  • Is research-based, data-driven
  • Shares stories of success—stories of people/role models using STEAM and critical thinking to make a difference
  • Provides a  variety of access points that are available to all learners

I was looking for more concrete information such as:

  • what is your budget?
  • which organizations are partners?
  • where do you get your funding?
  • what have you done so far?

I did get an answer to my last question by going to the Symbiosis news webpage where I found these,

We’re hiring!

Make of that what you will. Also, there is a 2018 copyright notice (at the bottom of the webpages) but no copyright owner is listed.

There is some Symbiosis information

A magazine known as BC Business (!) offers some details in a May 11, 2018 opinion piece, Note: Links have been removed,

… Increasingly, the Canadian marketplace is dominated by novel, knowledge-based jobs requiring high levels of literacy in STEM (science, technology, engineering and math). Here in B.C., the tech sector now employs over 100,000 people, about 5 percent of the province’s total workforce. As the knowledge economy grows, these numbers will rise dramatically.

Yet technology-driven businesses are already struggling to fill many roles that require literacy in STEM. …

Today, STEM education in North America and elsewhere is struggling. One study found that 60 percent of students who enter high school interested in STEM fields change their minds by graduation. Lacking mentoring, students, especially girls, tend to lose interest in STEM. [emphasis mine]Today, only 22 percent of Canadian STEM jobs are held by women. Failing to prepare the next generation to be STEM-literate threatens the prospects of our youth, our economy and the places we live.

More and more, education is no longer confined to classrooms. … To kickstart this future, a “STEM learning ecosystem” movement has emerged in the United States, grounded in deeply collaborative, cross-sector networks of learning opportunities.

Symbiosis will concentrate on a trio of impacts:

1) Dramatically increasing the number of qualified STEM mentors in B.C.—from teachers and scientists to technologists and entrepreneurs;

2) Connecting this diversity of mentors with children and youth through networked opportunities, from classroom visits and on-site shadowing to volunteering and internships; and

3) Creating a digital hub that interweaves communities, hosts a library of resources and extends learning through virtual offerings. [emphases mine]

Science World British Columbia is spearheading Symbiosis, and organizations from many sectors have expressed strong interest in collaborating—among them K-12 education, higher education, industry, government and non-profits. Several of these organizations are founding members of the BC Science Charter, which formed in 2013.

Symbiosis will launch in fall of 2018 with two pilot communities: East Vancouver and Prince George. …

As for why students tend to lose interest in STEM, there’s a rather interesting longitudinal study taking place in the UK which attempts to answer at least some of that question. I first wrote about the ASPIRES study in a January 31, 2012 posting: Science attitude kicks in by 10 years old. This was based on preliminary data and it seemed to be confirmed by an unrelated US study of high school students also mentioned in that posting (scroll down about 40% of the way).

In short, both studies suggested that children are quite to open to science but when it comes time to think about careers, they tend to ‘aspire’ to what they see amongst family and friends. I don’t see that kind of thinking reflected in any of the information I’ve been able to find about Symbiosis and it was not present in Sampson’s, Creative Mornings talk.

However, I noted during Sampson’s talk that he mentioned his father, a professor of psychology at the University of British Columbia and how he had based his career expectations on his father’s career. (Sampson is from Vancouver originally.) Sampson, like his father, was at one point a professor of ‘science’ at a university.

Perhaps one day someone from Symbiosis will look into the ASPIRE studies or even read my blog 🙂

You can find the latest about what is now called the ASPIRES 2 study here. (I will try to post my own update to the ASPIRES projects in the near future).

Best hopes

I am happy to see Symbiosis arrive on the scene and I wish all the best for the initiative. I am less concerned than the BC Business folks about supplying employers with the kind of employees they want to hire and hopeful that Symbiosis will attract not just the students, educators, mentors, and scientists to whom they are appealing but will cast a wider net to include philosophers, car mechanics, hairdressers, poets, visual artists, farmers, chefs, and others in a ‘pursuit of wonder’.

Aside: I was introduced to the phrase ‘pursuit of wonder’ by a friend who sent me a link to José Teodoro’s May 29, 2018 interview with Canadian filmmaker, Peter Mettler for the Brick. Mettler discusses his film about the Northern Lights and the technical challenges he met along the way.

Quantum Inkblot; An evening of physics, psychology, art and astronomy on July 12, 2018 in Vancouver (Canada)

A June 26, 2018 HR MacMillan Space Centre (HRMSC) press release, received via email, announces an upcoming art/sci event,

This July the H.R. MacMillan Space Centre and Voirelia: Dance, Psychology and Philosophy Hub will be co-hosting Quantum Inkblot, an interactive evening exploring quantum physics through the lenses of physics and psychology, art, and astronomy. The evening will incorporate talks by a physicist and a psychologist, visual artwork, and original contemporary dance performances.

The talks and artistic works will explore some of the questions about how psychology and physics can mirror, inspire, and influence one another. We will touch on topics related to relativity, uncertainty, and predictability of this world.

A dialogue-style talk will be led by physicist Dr. Jaymie Matthews and psychologist Dr. Alina Sotskova exploring the intersections of quantum physics and psychology. Dr. Matthews will be discussing the concept of wave-particle duality and the way it takes the assumption that one thing cannot be in two places at once and turns it on its head.

Dr. Sotskova will be talking about the dissonance in predicting the behaviour of groups vs. predicting the behaviour of individuals, giving pause to reflect on the existence of order at a macro level and chaos at the micro level.

The evening will also feature three original contemporary dance performances and a visual art and music presentation that were all inspired by themes in psychology and the intersection with physics.

There will be time between performances to enjoy a drink, take part in interactive art activities, watch physics demonstrations, and chat with physicists, artists, and psychologists. The evening will end with a question and answer period with all of the performers and speakers.

Here are logistics and additional details,

Quantum Inkblot will take place at the H.R. MacMillan Space Centre Thursday, July 12th.

This is a 19+ event.

6:30pm doors open, 7:00pm show starts in the Planetarium Star Theatre

$25 for tickets

Tickets available online through Eventbrite,[clicking on this link will give you a map to the location] in person, or by phone at 604.738.7827.

Find the Quantum Inkblot event on Facebook for sneak peeks at the art work being created, learn more about the process of collaboration between artists and scientists, and more!

The H.R. MacMillan Space Centre is a non-profit community resource that brings the wonders of space to Earth, while providing a personal sense of ongoing discovery. Through innovative programming, exhibits and activities, our goal is to inspire sustained interest in the fields of Earth science, space science and astronomy from a Canadian perspective.

Voirelia is a Vancouver-based Dance, Psychology, and Philosophy Hub. Its main purpose is to create original dance and art works inspired by ideas in psychology and philosophy. Voirelia also organizes talks, workshops, and events relevant to the intersection between dance, psychology, & philosophy, such as talks on philosophy of science. Our aim is “movement with meaning.”

BC Psychological Association has provided support for this event and BCPA representatives will be available to chat with the guests.

Voirelia provides a few more information and pictures on its Upcoming Projects webpage,

There will be several dance works presented during Quantum Inkblot. Here are the latest shots from one of the rehearsals, with physicists Dr. Jaymie Matthews and Dr. Ewan Hill joining us for a transdisciplinary open-rehearsal style session.

Photographs: Jason Kirkness. Dancers: Sophie Brassard, Michael Demski. Rehearsal direction/choreography: Alina Sotskova. [Not all the images have been included in this excerpt.]

 

We wanted to document our artistic and creative process as we put together this unique event. Below you will see examples of original art works and how artistic creation progresses. In the dance photographs below (by Jason Kirkness), we had a brainstorming session that included people with backgrounds in physics, psychology, dance, and theater. We spent about an hour talking about concepts from quantum physics that people often find “weird” – such as the concepts of waves, particles, wave-particle duality, and the uncertainty principle. We touched on how quantum physics influences our perception of science, the world, and ourselves. We discussed topics of identity and searching for meaning and why the quantum world is so different from what we see with our senses. Then we took our brainstorming to the dance studio. Here, using prompts suggested by physicists and her own knowledge as a psychologist and dancer, Alina Sotskova facilitated improvisational movement exploration. This yielded a great deal [sic] of ideas about parallels between physics and psychology, and we will use these ideas a spring board as we begin to develop specific dance works for the event. You can also check out short videos of the improvisational movement research session on our Facebook page, in the Videos section. [Not all the images have been included in this excerpt.]

The team who was part of the brainstorming session […] included: Andrew Elias (Graduate Student working in the field of quantum physics, UBC); Jason Kirkness (Co-lead for the Quantum Inkblot Event and; background: physics and computer science); Alina Sotskova (Co-lead for the Quantum Inkblot Event and; background: psychology and dance). Our dancers were: Angelo Moroni, Michael Demski, Carolyn Schmidt, Alejandra Miranda Caballero, Alina Sotskova.

The images below are samples of original art works by Andrew Short, one of Voirelia’s Core Consultants. Inspired by topics in quantum physics, psychology, and cosmology, Andrew is working on preparing a very special presentation especially for Quantum Inkblot. [There are more images at Voirelia.]

 

Interestingly, this does not seem to be a ‘sister’ event to Toronto’s ‘Out Of This World; Art inspired by all things astronomical’ exhibition and talks being held July 4 – 22, 2018 in honour of the Royal Astronomical Society of Canada’s (RASC) sesquicentennial (150th anniversary). There’s more about Toronto’s astronomical art/science event in my July 2, 2018 posting.

Out Of This World; Art inspired by all things astronomical from July 4 – 22, 2018 in Toronto, Canada

July 4 – 22  | Out Of This World | Juried Group Exhibition

“ Space… is big. Really big. You just won’t believe how vastly, hugely, mindbogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.”
– DOUGLAS ADAMS: THE HITCHHIKER’S GUIDE TO THE GALAXY (1979)


July 4 – 22  | Out of this World | Juried Group Exhibition
Opening Reception: Thurs. July 5th, 7 – 10 pm. (with telescopes! weather permitting… and astronomically-themed music from the 17th and 18th centuries)

2018 marks a century-and-a-half of the Royal Astronomical Society of Canada’s (RASC) promotion of astronomy and allied sciences in Canada. From early on, the RASC has encouraged exploring the connections of astronomy with other areas of culture, an interest which continues to the present. Propeller Gallery has partnered with the RASC to present an exhibition celebrating their sesquicentennial.

Astronomy, with its highly evocative imagery, and mindboggling and mindbending ideas about our Universe, provides artists with richly visual and deeply conceptual inspiration. Out of This World features a diverse array of work inspired by the cosmos, ranging from the visualization of astronomical data to textiles, video and installation. A select number of works from the archives of the RASC are also presented.

Participating Artists: Michael Black | Linda-Marlena Bucholtz Ross | David Cumming | Chris Domanski | Trinley Dorje | Dan Falk | Maya Foltyn | Peter Friedrichsen | Susan Gaby-Trotz | Aryan Ghaemmaghami | David Griffin | Xianda Guo, Charlotte Mueller, Sinead Lynch, Ramona Fluck, Christoph Blapp & Jayanne English | Diana Hamer | Chris Harms  | Angela Julian | Adam Kolodziej  | Irena IRiKO Kolodziej | Nancy Lalicon | Michelle Letarte | Shannon Leigh  | Elizabeth Lopez | Trevor McKinven | France McNeil  | John Ming Mark | Giuseppe Morano | Sarah Moreau  | Joseph Muscat  | Pria Muzumdar  | Neeko Paluzzi | Frances Patella | Donna Wells | Donna Wise | plus archival work from the Royal Astronomical Society of Canada

“Success in creating effective A.I.,” said the late Stephen Hawking, “could be the biggest event in the history of our civilization. Or the worst. We just don’t know.” Elon Musk called A.I. “a fundamental risk to the existence of civilization.” Are we creating the instruments of our own destruction or exciting tools for our future survival? Once we teach a machine to learn on its own—as the programmers behind AlphaGo have done, to wondrous results—where do we draw moral and computational lines? Leading specialists in A.I, neuroscience, and philosophy will tackle the very questions that may define the future of humanity.

“If I had a world of my own,” said the Mad Hatter, “nothing would be what it is, because everything would be what it isn’t. And contrary wise, what is, it wouldn’t be.” Nonsensical as this may sound, it comes close to describing an interesting paradox: You exist. You shouldn’t. Stars and galaxies and planets exist. They shouldn’t. The nascent universe contained equal parts matter and antimatter that should have instantly obliterated each other, turning the Big Bang into the Big Fizzle. And yet, here we are: flesh, blood, stars, moons, sky. Why? Come join us as we dive deep down the rabbit hole of solving the mystery of the missing antimatter.

Kerouac called it “the only truth.” Shakespeare called it “the food of love.” Maya Angelou called it “my refuge.” And now scientists are finally discovering what these thinkers, musicians, or even any of us with a Spotify account and a set of headphones could have told you on instinct: music lights up multiple corners of the brain, strengthening our neural networks, firing up memory and emotion, and showing us what it means to be human. In fact, music is as essential to being human as language and may even predate it. Can music also repair broken networks, restore memory, and strengthen the brain? Join us as we speak with neuroscientists and other experts in the fields of music and the brain as we pluck the notes of these fascinating phenomenon.

“Move fast and break things,” went the Silicon Valley rallying cry, and for a long time we cheered along. Born in dorm rooms and garages, implemented by iconoclasts in hoodies, Big Tech, in its infancy, spouted noble goals of bringing us closer. But now, in its adolescence, it threatens to tear us apart. Some worry about an “Infocalypse”: a dystopian disruption so deep and dire we will no longer trust anything we see, hear, or read. Is this pessimistic vision of the future real or hyperbole? Is it time for tech to slow down, grow up, and stop breaking things? Big names in Big Tech will offer big thoughts on this massive societal shift, its terrifying pitfalls, and practical solutions both for ourselves and for future generations.

AI fairytale and April 25, 2018 AI event at Canada Science and Technology Museum*** in Ottawa

These days it’s all about artificial intelligence (AI) or robots and often, it’s both. They’re everywhere and they will take everyone’s jobs, or not, depending on how you view them. Today, I’ve got two artificial intelligence items, the first of which may provoke writers’ anxieties.

Fairytales

The Princess and the Fox is a new fairytale by the Brothers Grimm or rather, their artificially intelligent surrogate according to an April 18, 2018 article on the British Broadcasting Corporation’s online news website,

It was recently reported that the meditation app Calm had published a “new” fairytale by the Brothers Grimm.

However, The Princess and the Fox was written not by the brothers, who died over 150 years ago, but by humans using an artificial intelligence (AI) tool.

It’s the first fairy tale written by an AI, claims Calm, and is the result of a collaboration with Botnik Studios – a community of writers, artists and developers. Calm says the technique could be referred to as “literary cloning”.

Botnik employees used a predictive-text program to generate words and phrases that might be found in the original Grimm fairytales. Human writers then pieced together sentences to form “the rough shape of a story”, according to Jamie Brew, chief executive of Botnik.

The full version is available to paying customers of Calm, but here’s a short extract:

“Once upon a time, there was a golden horse with a golden saddle and a beautiful purple flower in its hair. The horse would carry the flower to the village where the princess danced for joy at the thought of looking so beautiful and good.

Advertising for a meditation app?

Of course, it’s advertising and it’s ‘smart’ advertising (wordplay intended). Here’s a preview/trailer,

Blair Marnell’s April 18, 2018 article for SyFy Wire provides a bit more detail,

“You might call it a form of literary cloning,” said Calm co-founder Michael Acton Smith. Calm commissioned Botnik to use its predictive text program, Voicebox, to create a new Brothers Grimm story. But first, Voicebox was given the entire collected works of the Brothers Grimm to analyze, before it suggested phrases and sentences based upon those stories. Of course, human writers gave the program an assist when it came to laying out the plot. …

“The Brothers Grimm definitely have a reputation for darkness and many of their best-known tales are undoubtedly scary,” Peter Freedman told SYFY WIRE. Freedman is a spokesperson for Calm who was a part of the team behind the creation of this story. “In the process of machine-human collaboration that generated The Princess and The Fox, we did gently steer the story towards something with a more soothing, calm plot and vibe, that would make it work both as a new Grimm fairy tale and simultaneously as a Sleep Story on Calm.” [emphasis mine]

….

If Marnell’s article is to be believed, Peter Freedman doesn’t hold much hope for writers in the long-term future although we don’t need to start ‘battening down the hatches’ yet.

You can find Calm here.

You can find Botnik  here and Botnik Studios here.

What human speech, jazz, and whale song have in common

Seeing connections between what seem to be unrelated activities such as human speech, jazz, and whale song is fascinating to me and I’m not alone. Scientists at the University of California at Merced (UC Merced) have delivered handily on that premise according to an Oct. 13, 2017 news item on phys.org,

Jazz musicians riffing with each other, humans talking to each other and pods of killer whales all have interactive conversations that are remarkably similar to each other, new research reveals.

Cognitive science researchers at UC Merced have developed a new method for analyzing and comparing the sounds of speech, music and complex animal vocalizations like whale song and bird song. The paper detailing their findings is being published today [Oct. 12, 2017] in the Journal of the Royal Society Interface.

Their method is based on the idea that these sounds are complex because they have multiple layers of structure. Every language, for instance, has individuals sounds, roughly corresponding to letters, that combine to form syllables, words, phrases, sentences and so on. It’s a hierarchy that everyone understands intuitively. Musical compositions have their own temporal hierarchies, but until now there hasn’t been a way to directly compare the hierarchies of speech and music, or test whether similar hierarchies might exist in bird song and whale song.

An Oct. 12, 2017 UC Merced news release by Lorena Anderson, which originated the news item, provides more details about the investigation (Note: Links have been removed),

“Playing jazz music has been likened to a conversation among musicians, and killer whales are highly social creatures who vocalize as if they are talking to each other. But does jazz music really sound like a conversation, and do killer whales really sound like they are talking?” asked lead researcher and UC Merced professor Chris Kello. “We know killer whales are highly social and intelligent, but it’s hard to tell that they are interacting when you listen to recordings of them. Our method shows how much their sound patterns are like people talking, but not like other, less social whales or birds.”

The researchers figured out a way to measure and compare sound recordings by converting them into “barcodes” that capture clusters of sound energy, and clusters of clusters, across levels of a hierarchy. These barcodes allowed the researchers to directly compare temporal hierarchies in more than 200 recordings of different kinds of speech in six different languages, different kinds of popular and classical music, four different species of birds and whales singing their songs, and even thunderstorms.

Kello and his colleagues have been using the barcode method for several years. They first developed it in studies of conversations. The study published today is the first time that they applied the method to music and animal vocalizations.

“The method allows us to ask questions about language and music and animal songs that we couldn’t ask without a way to see and compare patterns in all these recordings,” Kello said.

Kello, fellow UC Merced cognitive science professor Ramesh Balasubramaniam, graduate student Butovens Me´de´ [or Médé] and collaborator professor Simone Dalla Bella also discovered that the haunting songs of huge humpback whales are remarkably similar to the beautiful songs of tiny nightingales and hermit thrushes in terms of their temporal hierarchies.

“Humpbacks, nightingales and hermit thrushes are solitary singers,” Kello said. “The barcodes show that their songs have similar layers of structure, but we don’t know what it means — yet.”

The idea for this project came from Kello’s sabbatical at the University of Montpellier in France, where he worked and discussed ideas with Dalla Bella. Balasubramaniam, who studies how music is perceived, is in the School of Social Sciences, Humanities and Arts with Kello, who studies speech and language processing. The project was a natural collaboration and is part of a growing research focus at UC Merced that was enabled by the National Science Foundation-funded CHASE summer school on Music and Language in 2014, and a Google Faculty Award to Kello.

Balasubramaniam is interested in continuing the work to better understand how brains distinguish between music and speech, while Kello said there are many different avenues to pursue.

For instance, the researchers found nearly identical temporal hierarchies for six different languages, which may suggest something universal about human speech. However, because this result was based on recordings of TED Talks — which have a common style and progression — Kello said it will be important to keep looking at other forms of speech and language.

One of his graduate students, Sara Schneider, is using the method to study the convergence of Spanish and English barcodes in bilingual conversations. Another graduate student, Adolfo Ramirez-Aristizabal, is working with Kello and Balasubramaniam to study whether the barcode method may shed light on how brains process speech and other complex sounds.

“Listening to music and speech, we can hear some of what we see in the barcodes, and the information may be useful for automatic classification of audio recordings. But that doesn’t mean that our brains process music and speech using these barcodes,” Kello said. “It’s intriguing, but we need to keep asking questions and go where the data lead us.”

Of musical parodies, Despacito, and evolution

What great timing, I just found out about a musical science parody featuring evolution and biology and learned of the latest news about the study of evolution on one of the islands in the Galapagos (where Charles Darwin made some of his observations). Thanks to Stacey Johnson for her November 24, 2017 posting on the Signals blog for featuring Evo-Devo (Despacito Biology Parody), an A Capella Science music video from Tim Blais,

Now, for the latest regarding the Galapagos and evolution (from a November 24, 2017 news item on ScienceDaily),

The arrival 36 years ago of a strange bird to a remote island in the Galapagos archipelago has provided direct genetic evidence of a novel way in which new species arise.

In this week’s issue of the journal Science, researchers from Princeton University and Uppsala University in Sweden report that the newcomer belonging to one species mated with a member of another species resident on the island, giving rise to a new species that today consists of roughly 30 individuals.

The study comes from work conducted on Darwin’s finches, which live on the Galapagos Islands in the Pacific Ocean. The remote location has enabled researchers to study the evolution of biodiversity due to natural selection.

The direct observation of the origin of this new species occurred during field work carried out over the last four decades by B. Rosemary and Peter Grant, two scientists from Princeton, on the small island of Daphne Major.

A November 23, 2017 Princeton University news release on EurekAlert, which originated the news item, provides more detail,

“The novelty of this study is that we can follow the emergence of new species in the wild,” said B. Rosemary Grant, a senior research biologist, emeritus, and a senior biologist in the Department of Ecology and Evolutionary Biology. “Through our work on Daphne Major, we were able to observe the pairing up of two birds from different species and then follow what happened to see how speciation occurred.”

In 1981, a graduate student working with the Grants on Daphne Major noticed the newcomer, a male that sang an unusual song and was much larger in body and beak size than the three resident species of birds on the island.

“We didn’t see him fly in from over the sea, but we noticed him shortly after he arrived. He was so different from the other birds that we knew he did not hatch from an egg on Daphne Major,” said Peter Grant, the Class of 1877 Professor of Zoology, Emeritus, and a professor of ecology and evolutionary biology, emeritus.

The researchers took a blood sample and released the bird, which later bred with a resident medium ground finch of the species Geospiz fortis, initiating a new lineage. The Grants and their research team followed the new “Big Bird lineage” for six generations, taking blood samples for use in genetic analysis.

In the current study, researchers from Uppsala University analyzed DNA collected from the parent birds and their offspring over the years. The investigators discovered that the original male parent was a large cactus finch of the species Geospiza conirostris from Española island, which is more than 100 kilometers (about 62 miles) to the southeast in the archipelago.

The remarkable distance meant that the male finch was not able to return home to mate with a member of his own species and so chose a mate from among the three species already on Daphne Major. This reproductive isolation is considered a critical step in the development of a new species when two separate species interbreed.

The offspring were also reproductively isolated because their song, which is used to attract mates, was unusual and failed to attract females from the resident species. The offspring also differed from the resident species in beak size and shape, which is a major cue for mate choice. As a result, the offspring mated with members of their own lineage, strengthening the development of the new species.

Researchers previously assumed that the formation of a new species takes a very long time, but in the Big Bird lineage it happened in just two generations, according to observations made by the Grants in the field in combination with the genetic studies.

All 18 species of Darwin’s finches derived from a single ancestral species that colonized the Galápagos about one to two million years ago. The finches have since diversified into different species, and changes in beak shape and size have allowed different species to utilize different food sources on the Galápagos. A critical requirement for speciation to occur through hybridization of two distinct species is that the new lineage must be ecologically competitive — that is, good at competing for food and other resources with the other species — and this has been the case for the Big Bird lineage.

“It is very striking that when we compare the size and shape of the Big Bird beaks with the beak morphologies of the other three species inhabiting Daphne Major, the Big Birds occupy their own niche in the beak morphology space,” said Sangeet Lamichhaney, a postdoctoral fellow at Harvard University and the first author on the study. “Thus, the combination of gene variants contributed from the two interbreeding species in combination with natural selection led to the evolution of a beak morphology that was competitive and unique.”

The definition of a species has traditionally included the inability to produce fully fertile progeny from interbreeding species, as is the case for the horse and the donkey, for example. However, in recent years it has become clear that some closely related species, which normally avoid breeding with each other, do indeed produce offspring that can pass genes to subsequent generations. The authors of the study have previously reported that there has been a considerable amount of gene flow among species of Darwin’s finches over the last several thousands of years.

One of the most striking aspects of this study is that hybridization between two distinct species led to the development of a new lineage that after only two generations behaved as any other species of Darwin’s finches, explained Leif Andersson, a professor at Uppsala University who is also affiliated with the Swedish University of Agricultural Sciences and Texas A&M University. “A naturalist who came to Daphne Major without knowing that this lineage arose very recently would have recognized this lineage as one of the four species on the island. This clearly demonstrates the value of long-running field studies,” he said.

It is likely that new lineages like the Big Birds have originated many times during the evolution of Darwin’s finches, according to the authors. The majority of these lineages have gone extinct but some may have led to the evolution of contemporary species. “We have no indication about the long-term survival of the Big Bird lineage, but it has the potential to become a success, and it provides a beautiful example of one way in which speciation occurs,” said Andersson. “Charles Darwin would have been excited to read this paper.”
