Scientific evidence and certainty: a controversy in the US Justice system

Leave a reply

It seems that forensic evidence does not deliver the certainty that television and US prosecutors (I wonder if Canadian Crown Attorneys or Crown Counsels concur with their US colleagues?) would have us believe. The US President’s Council of Advisors on Science and Technology (PCAST) released a report (‘Forensic Science in Criminal Courts: Ensuring Scientific Validity of Feature-Comparison Methods‘ 174 pp PDF) on Sept. 20, 2016 that amongst other findings, notes that more scientific rigour needs to be applied to the field of forensic science.

Here’s more from the Sept. 20, 2016 posting by Eric Lander, William Press, S. James Gates, Jr., Susan L. Graham, J. Michael McQuade, and Daniel Schrag, on the White House blog,

The study that led to the report was a response to the President’s question to his PCAST in 2015, as to whether there are additional steps on the scientific side, beyond those already taken by the Administration in the aftermath of a highly critical 2009 National Research Council report on the state of the forensic sciences, that could help ensure the validity of forensic evidence used in the Nation’s legal system.

PCAST concluded that two important gaps warranted the group’s attention: (1) the need for clarity about the scientific standards for the validity and reliability of forensic methods and (2) the need to evaluate specific forensic methods to determine whether they have been scientifically established to be valid and reliable. The study aimed to help close these gaps for a number of forensic “feature-comparison” methods—specifically, methods for comparing DNA samples, bitemarks, latent fingerprints, firearm marks, footwear, and hair.

In the course of its year-long study, PCAST compiled and reviewed a set of more than 2,000 papers from various sources, educated itself on factual matters relating to the interaction between science and the law, and obtained input from forensic scientists and practitioners, judges, prosecutors, defense attorneys, academic researchers, criminal-justice-reform advocates, and representatives of Federal agencies.

…

A Sept. 23, 2016 article by Daniel Denvir for Salon.com sums up the responses from some of the institutions affected by this report,

Under fire yet again, law enforcement is fighting back. Facing heavy criticism for misconduct and abuse, prosecutors are protesting a new report from President Obama’s top scientific advisors that documents what has long been clear: much of the forensic evidence used to win convictions, including complex DNA samples and bite mark analysis, is not backed up by credible scientific research.

Although the evidence of this is clear, many in law enforcement seem terrified that keeping pseudoscience out of prosecutions will make them unwinnable. Attorney General Loretta Lynch declined to accept the report’s recommendations on the admissibility of evidence and the FBI accused the advisors of making “broad, unsupported assertions.” But the National District Attorneys Association, which represents roughly 2,5000 top prosecutors nationwide, went the furthest, taking it upon itself to, in its own words, “slam” the report.

Prosecutors’ actual problem with the report, produced by some of the nation’s leading scientists on the President’s Council of Advisors on Science and Technology, seems to be unrelated to science. Reached by phone NDAA president-elect Michael O. Freeman could not point to any specific problem with the research and accused the scientists of having an agenda against law enforcement.

“I’m a prosecutor and not a scientist,” Freeman, the County Attorney in Hennepin County, Minnesota, which encompasses Minneapolis, told Salon. “We think that there’s particular bias that exists in the folks who worked on this, and they were being highly critical of the forensic disciplines that we use in investigating and prosecuting cases.”

That response, devoid of any reference to hard science, has prompted some mockery, including from Robert Smith, Senior Research Fellow and Director of the Fair Punishment Project at Harvard Law School, who accused the NDAA of “fighting to turn America’s prosecutors into the Anti-Vaxxers, the Phrenologists, the Earth-Is-Flat Evangelists of the criminal justice world.”

It has also, however, also lent credence to a longstanding criticism that American prosecutors are more concerned with winning than in establishing a defendant’s guilt beyond a reasonable doubt.

“Prosecutors should not be concerned principally with convictions; they should be concerned with justice,” said Daniel S. Medwed, author of “Prosecution Complex: America’s Race to Convict and Its Impact on the Innocent” and a professor at Northern University School of Law, told Salon. “Using dodgy science to obtain convictions does not advance justice.”

Denvir’s article is lengthier and worth reading in its entirety.

Assuming there’s an association of forensic scientists, I find it interesting they don’t appear to have responded.

Finally, if there’s one thing you learn while writing about science it’s that there is no real certainty. For example, if you read about the Higgs boson discovery, you’ll note that the scientists involved the research never stated with absolute certainty that it exists but rather they ‘were pretty darn sure’ it does (I believe the scientific term is 5-sigma). There’s more about the Higgs boson and 5-sigma in this July 17, 2012 article by Evelyn Lamb for Scientific American,

In short, five-sigma corresponds to a p-value, or probability, of 3×10-7, or about 1 in 3.5 million. This is not the probability that the Higgs boson does or doesn’t exist; rather, it is the probability that if the particle does not exist, the data that CERN [European Particle Physics Laboratory] scientists collected in Geneva, Switzerland, would be at least as extreme as what they observed. “The reason that it’s so annoying is that people want to hear declarative statements, like ‘The probability that there’s a Higgs is 99.9 percent,’ but the real statement has an ‘if’ in there. There’s a conditional. There’s no way to remove the conditional,” says Kyle Cranmer, a physicist at New York University and member of the ATLAS team, one of the two groups that announced the new particle results in Geneva on July 4 [2012].

For the interested, there’s a lot more to Lamb’s article.

Getting back to forensic science, this PCAST report looks like an attempt to bring forensics back into line with the rest of the science world.

D-PLACE: an open access database of places, language, culture, and enviroment

Leave a reply

In an attempt to be a bit more broad in my interpretation of the ‘society’ part of my commentary I’m including this July 8, 2016 news item on ScienceDaily (Note: A link has been removed),

An international team of researchers has developed a website at d-place.org to help answer long-standing questions about the forces that shaped human cultural diversity.

D-PLACE — the Database of Places, Language, Culture and Environment — is an expandable, open access database that brings together a dispersed body of information on the language, geography, culture and environment of more than 1,400 human societies. It comprises information mainly on pre-industrial societies that were described by ethnographers in the 19th and early 20th centuries.

A July 8, 2016 University of Toronto news release (also on EurekAlert), which originated the news item, expands on the theme,

“Human cultural diversity is expressed in numerous ways: from the foods we eat and the houses we build, to our religious practices and political organisation, to who we marry and the types of games we teach our children,” said Kathryn Kirby, a postdoctoral fellow in the Departments of Ecology & Evolutionary Biology and Geography at the University of Toronto and lead author of the study. “Cultural practices vary across space and time, but the factors and processes that drive cultural change and shape patterns of diversity remain largely unknown.

“D-PLACE will enable a whole new generation of scholars to answer these long-standing questions about the forces that have shaped human cultural diversity.”

Co-author Fiona Jordan, senior lecturer in anthropology at the University of Bristol and one of the project leads said, “Comparative research is critical for understanding the processes behind cultural diversity. Over a century of anthropological research around the globe has given us a rich resource for understanding the diversity of humanity – but bringing different resources and datasets together has been a huge challenge in the past.

“We’ve drawn on the emerging big data sets from ecology, and combined these with cultural and linguistic data so researchers can visualise diversity at a glance, and download data to analyse in their own projects.”

D-PLACE allows users to search by cultural practice (e.g., monogamy vs. polygamy), environmental variable (e.g. elevation, mean annual temperature), language family (e.g. Indo-European, Austronesian), or region (e.g. Siberia). The search results can be displayed on a map, a language tree or in a table, and can also be downloaded for further analysis.

It aims to enable researchers to investigate the extent to which patterns in cultural diversity are shaped by different forces, including shared history, demographics, migration/diffusion, cultural innovations, and environmental and ecological conditions.

D-PLACE was developed by an international team of scientists interested in cross-cultural research. It includes researchers from Max Planck Institute for the Science of Human history in Jena Germany, University of Auckland, Colorado State University, University of Toronto, University of Bristol, Yale, Human Relations Area Files, Washington University in Saint Louis, University of Michigan, American Museum of Natural History, and City University of New York.

The diverse team included: linguists; anthropologists; biogeographers; data scientists; ethnobiologists; and evolutionary ecologists, who employ a variety of research methods including field-based primary data collection; compilation of cross-cultural data sources; and analyses of existing cross-cultural datasets.

“The team’s diversity is reflected in D-PLACE, which is designed to appeal to a broad user base,” said Kirby. “Envisioned users range from members of the public world-wide interested in comparing their cultural practices with those of other groups, to cross-cultural researchers interested in pushing the boundaries of existing research into the drivers of cultural change.”

Here’s a link to and a citation for the paper,

While it might not seem like that there would be a close link between anthropology and physics in the 19th and early 20th centuries, that information can be mined for more contemporary applications. For example, someone who wants to make a case for a more diverse scientific community may want to develop a social science approach to the discussion. The situation in my June 16, 2016 post titled: Science literacy, science advice, the US Supreme Court, and Britain’s House of Commons, could  be extended into a discussion and educational process using data from D-Place and other sources to make the point,

Science literacy may not be just for the public, it would seem that US Supreme Court judges may not have a basic understanding of how science works. David Bruggeman’s March 24, 2016 posting (on his Pasco Phronesis blog) describes a then current case before the Supreme Court (Justice Antonin Scalia has since died), Note: Links have been removed,

…

It’s a case concerning aspects of the University of Texas admissions process for undergraduates and the case is seen as a possible means of restricting race-based considerations for admission.  While I think the arguments in the case will likely revolve around factors far removed from science and or technology, there were comments raised by two Justices that struck a nerve with many scientists and engineers.

Both Justice Antonin Scalia and Chief Justice John Roberts raised questions about the validity of having diversity where science and scientists are concerned [emphasis mine].  Justice Scalia seemed to imply that diversity wasn’t esential for the University of Texas as most African-American scientists didn’t come from schools at the level of the University of Texas (considered the best university in Texas).  Chief Justice Roberts was a bit more plain about not understanding the benefits of diversity.  He stated, “What unique perspective does a black student bring to a class in physics?”

To that end, Dr. S. James Gates, theoretical physicist at the University of Maryland, and member of the President’s Council of Advisers on Science and Technology (and commercial actor) has an editorial in the March 25 [2016] issue of Science explaining that the value of having diversity in science does not accrue *just* to those who are underrepresented.

Dr. Gates relates his personal experience as a researcher and teacher of how people’s background inform their practice of science, and that two different people may use the same scientific method, but think about the problem differently.

I’m guessing that both Scalia and Roberts and possibly others believe that science is the discovery and accumulation of facts. In this worldview science facts such as gravity are waiting for discovery and formulation into a ‘law’. They do not recognize that most science is a collection of beliefs and may be influenced by personal beliefs. For example, we believe we’ve proved the existence of the Higgs boson but no one associated with the research has ever stated unequivocally that it exists.

More generally, with D-PLACE and the recently announced Trans-Atlantic Platform (see my July 15, 2016 post about it), it seems Canada’s humanities and social sciences communities are taking strides toward greater international collaboration and a more profound investment in digital scholarship.

Help find some siblings for the Higgs boson

Leave a reply

This is the Higgs Hunters’ (or HiggsHunters) second call for volunteers; the first was described in my Dec. 2, 2014 posting. Some 18 months after the first call, over 20,000 volunteers have been viewing images from the Large Hadron Collider in a bid to assist physicists at CERN (European Organization for Nuclear Research).

These images show how particles appear in the ATLAS detector. The lines show the paths of charged particles travelling away from a collision at the centre. Volunteers are looking for tracks appearing 'out of thin air' away from the centre. (Image: CERN)

A July 6, 2016 news item on phys.org announces the call for more volunteers (Note: Links have been removed),

A citizen science project, called HiggsHunters gives everyone the chance to help search for the Higgs boson’s relatives.

Volunteers are searching through thousands of images from the ATLAS experiment on the HiggsHunters.org website, which makes use of the Zooniverse  citizen science platform.

They are looking for ‘baby Higgs bosons’, which leave a characteristic trace in the ATLAS detector.

This is the first time that images from the Large Hadron Collider have been examined on such a scale – 60,000 of the most interesting events were selected from collisions recorded throughout 2012 – the year of the Higgs boson discovery. About 20,000 of those collisions have been scanned so far, revealing interesting features.

A July 4, 2016 posting by Harriet Kim Jarlett on Will Kalderon’s CERN blog, which originated the news item, provides more details,

“There are tasks – even in this high-tech world – where the human eye and the human brain simply win out,” says Professor Alan Barr of the University of Oxford, who is leading the project.

Over the past two years, more than twenty thousand amateur scientists, from 179 countries, have been scouring images of LHC collisions,  looking for as-yet unobserved particles.

Dr Will Kalderon, who has been working on the project says “We’ve been astounded both by the number of responses and ability of people to do this so well, I’m really excited to see what we might find”.

July 4, 2016 was the fourth anniversary of the  confirmation that the Higgs Boson almost certainly exists (from the CERN blog),

Today, July 4 2016, is the fourth birthday of the Higgs boson discovery. Here, a toy Higgs is sat on top of a birthday cake decorated with a HiggsHunter event display. On the blackboard behind is the process people are looking for - Higgs-strahlung. (Image: Will Kalderon/CERN)

Become a Higgs Hunter (anyone can do it)

Leave a reply

The Higgs you’d be hunting is a Higgs boson; the one that was confirmed to worldwide jubilation in 2012. (For anyone not familiar with the Higgs, I have a Dec. 14, 2011 post which provides a introductory video from the US Fermi Lab along with more information.)

Thanks to David Bruggeman and a Nov. 29, 2014 post on his Pasco Phronesis blog I have additional details about this citizen science, aka, crowdsourced science, project,

If you accept the assignment, Higgs Hunters will provide you several particle images from the ATLAS detector at CERN.  Mark any tracks that are off-centre in the images and move on to the next.  The tracks represent decay of exotic particles, particles that could have resulted from the decay of the Higgs boson.

Here’s more from a Science Magazine Nov. 26, 2014 posting (Note: Links have been removed),

Today [Nov. 26, 2014] marks the beginning of your chance to hunt for tiny explosions that could eventually lead to entirely new physics. Head to higgshunters.org to help scientists analyze 25,000 images from CERN’s particle collider, but be warned, you’ll be looking for evidence of the Higgs boson’s death. Some scientists believe that when the Higgs boson decays, it leaves behind other, completely new particles. …

Higgshunters.org has prepared its own video introduction to the project,

For those who prefer text, Higgs Hunters has this to say on its Introductory page,

In 2012, the world of Particle Physics rejoiced with the discovery of the long sought after Higgs boson particle. But this is just the beginning. In our search for answers to the most fundamental questions about the nature of reality, we are looking for your help in finding evidence of new physics beyond our current understanding. Through searching for exotic decays (particles falling apart in unexpected ways) in the Large Hadron Collider’s particle collisions, you can be a part of the next great revolution in Physics. The LHC’s computer programs were not designed to look for these decays, but we are willing to bet that a keen pair of human eyes can. So how about it, are you ready to change our understanding of the world?

On its How you can help page, the Higgs Hunters scientists describe the magnitude of the project and The Zooniverse (a citizen science organization), which is providing the platform for this project Note: Links have been removed,

Particle colliders produce a huge amount of data – so large in fact that the world-wide web was invented at CERN so scientists could share the data with each other to handle it. CERN now has a global computing grid of 170 computing centres in 40 countries trawling through the data, but computers are far from perfect. Unlike the human brain, which is naturally curious and excellent at pattern recognition, computer programs can only find what they have been taught how to find.

The Zooniverse has a rich history of making new discoveries that computers had completely missed (some older members will recall the excitement surrounding ‘Hanny’s Voorwerp’ found by a citizen scientist working on the Galaxy Zoo project). In this spirit, we need your help to look for the weird and wonderful secrets hiding in the LHC data. In doing so, you will also be teaching our computers how to better spot exotic particle events, speeding up the process of future scientific discoveries! To do this Higgs Hunters shows you a combination of simulated and real data. We need to understand what kind of events can be ‘detected’ using this site, and so we include computer-generated data as well as real data. You’ll be told after each classification if it was a simulation.

With your help, we can collectively improve our understanding of the universe. The next new discovery is waiting to be found!

Good luck!

I last mentioned The Zooniverse and citizen science in a Nov. 19, 2014 post about the upcoming American Association for the Advancement of Science (AAAS) 2015 meeting in California. Citizen science will be discussed in presentations at the meeting and also at the  Citizen Science Association’s first conference (which is being held as a pre-AAAS 2015 meeting conference).

Quantum; the dance performance about physics in Vancouver, Canada (2 of 2)

Leave a reply

Gilles Jobin kindly made time to talk about his arts residency at CERN (European Particle Physics Laboratory) prior to the performances of Quantum (a dance piece resulting from the residency) from Oct. 16 -18, 2014 at Vancouver’s Dance Centre.

Jobin was the first individual to be selected as an artist-in-residence for three months in the CERN/Geneva programme (there is another artist-in-residence programme at the laboratory which is the CERN/Ars Electronica programme). Both these artist-in-residence programmes were announced in the same year, 2011. (You can find out more about the CERN artist-in-residence programmes on the Collide@CERN webpage,

As a main strategy of CERN’s Cultural Policy for Engaging with the Arts, Collide@CERN is a 3-year artist’s residency programme initiated by Arts@CERN in 2011.

By bringing world-class artists and scientists together in a free exchange of ideas, the Collide@CERN residency programme explores elements even more elusive than the Higgs boson: human ingenuity, creativity and imagination.

See below for more information about the Collide@CERN artist residency programmes:

Collide@CERN Geneva Residency

Prix Ars Electronica Collide@CERN Residency

The Collide@CERN prize – an open call to artists working in different art forms to win a fully funded residency – will be awarded annually in two strands (Collide@CERN Geneva and Prix Ars Electronica Collide@CERN) until 2013. It comprises prize money and a residency grant for up to 3 months at CERN.

The winning artists will interact and engage with CERN scientists in order to take their artistic work to new creative dimensions.

The awards are made following two annual international open calls and the jury comprises the cultural partners as well as representatives from Arts@CERN, including scientists.

Planned engagement with artists at CERN is a relatively new concept according to an August 4, 2011 CERN press release,

Today CERN1 launches its cultural policy for engaging with the arts. Called ‘Great Arts for Great Science’, this new cultural policy has a central strategy – a selection process for arts engagement at the level of one of the world’s leading research organizations.

“This puts CERN’s engagement with the arts on a similar level as the excellence of its science,” said Ariane Koek, CERN’s cultural specialist.

CERN’s newly appointed Cultural Board for the Arts will be the advisers and guardians of quality. It is made up of renowned cultural leaders in the arts from CERN’s host-state countries: Beatrix Ruf, Director of the Kunsthalle Zurich; Serge Dorny, Director General of the Lyon Opera House; Franck Madlener, Director of the music institute IRCAM in Paris. Geneva and CERN are represented by Christoph Bollman of ArtbyGenève and Michael Doser, an antimatter scientist. Membership of the board is an honorary position that will change every three years.

The Cultural Board will select one or two art projects a year to receive a CERN letter of approval, enabling these projects to seek external funding for their particle-physics inspired work. This will also build up an international portfolio of CERN-inspired work over the years to come, in conjunction with the Collide@CERN (link sends e-mail) Artists Residency Programme, details of which will be announced in the coming month.

To date, Jobin is the only choreographer to become, so to speak, a member of the CERN community. It was a position that was treated like a job. Jobin went to his office at CERN every day for three months to research particle physics. He had two science advisors, Nicholas Chanon and Michael Doser to help him gain an understanding of the physics being studied in the facility. Here’s Jobin describing his first experiences at CERN (from Jobin’s Collide Nov. 13, 2012 posting),

When I first arrived at Cern, I was captivated by the place and overwhelmed by the hugeness of the subject: Partical [sic] physics… And I had some serious catch up to do… Impressed by the two introduction days in which I had the opportunity to meet many different scientists, Ariane Koeck told me “not to panic” and “to spend my first month following my instinct and not my head…”. …

…

I found out about the 4 fundamental forces and the fact that gravity was the weakest of all the forces. For a contemporary dancer formed basically around the question of gravity and “groundness” that came as a total shock! I was not a “pile of stuff”, but particles bound together by the strong force and “floating” on the surface of the earth… Me, the earth, you readers, the LHC flying at incredible speed through space, without any of us, (including the physicists!) noticing anything…  Stardust flying into space… I was baffled…

…

Jobin was required deliver two public lectures, one at the beginning of his residency and the other at the end, as well as, a series of ‘interventions’. He instituted four ‘interventions’, one each in CERN’s library, data centre, anti-matter hall, and cafeteria. Here’s an image and a description of what Jobin was attempting with his library intervention (from his Nov. 13, 2012 posting),

CERN library dance intervention Credit: Gilles Jobin

CERN library dance intervention Credit: Gilles Jobin

 My idea was to “melt” our bodies into the timeline of the library. Like time chameleons, we were to adapt our movements and presence to the quiet and studious atmosphere of the library and be practically unnoticed. My postulate was to imagine that the perception of time is relative; there was a special texture to “time” inside the library. How long is an afternoon in a library? Never ending or passing by too quickly? It is a shared space, with the unique density you can feel in studious atmosphere and its user’s different virtual timelines. We melted into the element of the library and as we guessed, our “unusual” presence and actions did not create conflicts with our surroundings and the students at work. It was a bit like entering slowly into water and becoming part of the element without disturbing its balance. The time hypothesis worked… I wanted to do more site specific interventions in Cern because I was learning things differently. Some understanding was going through my body. Being in action into the labs…

It was only after the residency was completed that he started work on Quantum (producing a dance piece was not a requirement of the residency). After the residency, he did bring his science advisors, Chanon and Doser to his studio and brought his studio to CERN. Jobin managed to get rehearsal time in one of the halls that is 100 metres directly above the large hadron collider (LHC) during the time period when scientists were working to confirm the existence of the Higgs Boson). There were a number of announcements ‘confirming’ the Higgs. They started in July 2012 and continued, as scientists refined their tests, to March 2013 (Wikipedia entry)  when a definitive statement was issued. The definitive statement was recently followed with more confirmation as a June, 25, 2014 article by Amir Aczel for Discover declares Confirmed: That Was Definitely the Higgs Boson Found at LHC [large hadron collider].

As scientists continue to check and doublecheck, Jobin presented Quantum in October 2013 for the first time in public, fittingly, at CERN (from Jobin’s Oct. 3, 2013 blog posting),

Jobin was greatly influenced by encounters at CERN with Julius von Bismarck who won the 2012 Prix Ars Electronica Collide@CERN Residency and with his science advisors, Dosen and Chanon. Surprisingly, Jobin was also deeply influenced by Richard Feynman (American physicist; 1918 – 1988). “I loved his approach and his humour,” says Jobin while referring to a book Feynman wrote, then adding,  “I used Feynman diagrams, learning to draw them for my research and for my choreographic work on Quantum.”

For those unfamiliar with Feynman diagrams, from the Wikipedia entry (Note: Links have been removed),

In theoretical physics, Feynman diagrams are pictorial representations of the mathematical expressions describing the behavior of subatomic particles. The scheme is named for its inventor, American physicist Richard Feynman, and was first introduced in 1948. The interaction of sub-atomic particles can be complex and difficult to understand intuitively, and the Feynman diagrams allow for a simple visualization of what would otherwise be a rather arcane and abstract formula.

There’s also an engaging Feb. 14, 2010 post by Flip Tanedo on Quantum Diaries with this title, Let’s draw Feynman diagrams! and there’s this paper, by David Kaiser on the Massachusetts Institute of Technology website, Physics and Feynman’s Diagrams; In the hands of a postwar generation, a tool intended to lead quantum electrodynamics out of a decades-long morass helped transform physics. In the spirit of Richard Feynman, both the Tanedo post and Kaiser paper are quite readable. Also, here’s an example (simplified) of what a diagram (from the Quantum Diaries website) can look like,

[downloaded from http://www.quantumdiaries.org/2010/02/14/lets-draw-feynman-diagams/]

Getting back to Quantum (dance), Jobin describes this choreography as a type of collaboration where the dancers have responsibility for the overall look and feel of the piece. (For more details, Jobin describes his ‘momement generators’ in the radio interview embedded in part 1 of this piece on Quantum.)

In common with most contemporary dance pieces, there is no narrative structure or narrative element to the piece although Jobin does note that there is one bit that could be described as a ‘Higgs moment’ where a dancer is held still by his or her feet, signifying the Higgs boson giving mass to the universe.

As to why Vancouver, Canada is being treated to a performance of Quantum, Jobin has this to say, “When I knew the company was traveling to New York City and then San Francisco, I contacted my friend and colleague, Mirna Zagar, who I met at a Croatian Dance Week Festival that she founded and produces every year.”  She’s also the executive director for Vancouver’s Dance Centre. “After that it was easy.”

Performances are Oct. 16 – 18, 2014 at 8 pm with a Post-show artist talkback on October 17, 2014.

You can find part 1 of this piece about Quantum in my Oct. 15, 2014 posting. which includes a video, a listing of the rest of the 2014 tour stops, a link to an interview featuring Jobin and his science advisor, Michael Doser, on a US radio show, and more.

Finally, company dancers are posting video interviews (the What’s Up project mentioned in part 1) with dancers they meet in the cities where the tour is stopping will be looking for someone or multiple someones in Vancouver. These are random acts of interviewing within the context of the city’s dance community.

Vancouver’s Georgia Straight has featured an Oct. 15, 2014 article by Janet Smith about Jobin and his particle physics inspiration for Quantum.

The Higgs boson on its own has inspired other creativity as noted in my Aug. 1, 2012 posting (Playing and singing the Higgs Boson).

As noted in my Oct. 8, 2013 post, Peter Higgs (UK) after whom the particle was named  and François Englert (Belgium) were both awarded the 2013 Nobel Prize in Physics for their contributions to the theory of the Higgs boson and its role in the universe.

Liverpool Science Festival

Leave a reply

The first Liverpool Science Festival (UK)  is being held June 25 – July 9, 2014 according to a June 6, 2014 Festival announcement, which has a very exciting lineup guests and events,

Liverpool Science Festival was founded with the mission to create a unique platform to engage the public in all things scientific – from natural science to science in its most interdisciplinary and cultural contexts.

For 2014, we are part of the science programme of events during the UK’s inaugural International Festival for Business (IFB 2014). We are also proud to be contributing events to the official 60th Anniversary celebrations of CERN – birthplace of the internet, the Large Hadron Collider (LHC), site of the discovery of the Higgs Boson – and home to scientists from more than 100 countries.

Highlights of the festival include:

The Hitchhiker’s Guide to the Solar System:
1 river, 9 planets, 14 days and 70 miles

An ambitious public engagement project setting off from the source of the Mersey on a journey to the sea, culminating in a series of pop-up astronomy events and happenings which will mark out the positions of the planets and a scale model of the Solar System. The journey begins on 25 June with astronomy at the source of the Mersey (Stockport, Cheshire) and ends on the evening of 9 July on Crosby Beach.

This is the second reference to the Hitchhiker’s Guide to the Galaxy that I’ve had on this blog in less than one week. Rice University (US) researcher, Nikta Fakhri, referenced the book in a description of her work on carbon nanotubes in a June 5, 2014 post titled, Hitchhikers at the nanoscale show how cells stir themselves. (For anyone unfamiliar with the book and/or its cultural import, here’s a Wikipedia entry devoted to it.)

Next the festival is featuring its physics with two live events, one featuring Jon Butterworth and the other featuring Butterworth and Lyn Evans (from the announcement),

“If you want to know what being a professional scientist is really like, read Smashing Physics!” – Professor Brian Cox

Professor Jon Butterworth (CERN {European Organization for Nuclear Research ], UCL [University College of London] & Guardian Science) at Waterstones Liverpool One on 27 June – one of the UK’s foremost physicists, on Smashing Physics, his smashing new science book about the hunt for Higgs Boson and real life as a real scientist at the cusp of scientific discovery.

www.liverpoolsciencefestival.com/smashing-physics-ft-prof-jon-butterworth  

Dr Lyn Evans (chief engineer at CERN who spent 15 years leading the team constructing the LHC, the most complex machine ever built) flies in from CERN, Geneva, to speak on Engineering the LHCon 28 June at Stanley Dock.

www.liverpoolsciencefestival.com/engineering-the-lhc-ft-prof-jon-butterworth-dr-lyn-evans

Butterworth has a blog, Life and Physics, hosted by the Guardian newspaper as part of its science blog network. I find his writing to be quite approachable. From time to time he starts talking in ‘physics’ but he usually prepares his audience for these brief outbursts by explaining the concept first in plain English and/or approaching the topic from a mundane angle, e.g., ‘it can be lonely being a physicist’.

Evans was in Vancouver, Canada last February 2013 to launch a global project (from a Feb. 18, 2013 news release posted on The Exchange),

… On February 21 [2013], TRIUMF will do its part in fulfilling this role as it plays host to a meeting of the leaders of the major high-energy physics laboratories around the world. The key outcome of this meeting will be the completion of an existing global collaboration and the launch of a new team that will coordinate and advance the global development work for the Linear Collider, the world’s next accelerator project aimed at pulling back the curtain on the secrets of nature’s most innermost workings.

The new Linear Collider Collaboration (LCC) will combine the two next-generation collider projects, the International Linear Collider (ILC) and the Compact Linear Collider (CLIC), under one organizational roof and will be headed by Lyn Evans, former Project Manager of CERN’s Large Hadron Collider (LHC). Some may recognize Lyn Evans as recent co-recipient of the Milner Foundation’s Fundamental Physics Prize. (Evans will give a public science lecture on Wednesday evening at Science World.)

The Linear Collider Board, headed by the University of Tokyo’s Sachio Komamiya, is a new oversight committee for the LCC that will take up office at the same time.

Evans’ public talk mentioned in my Jan. 29, 2013 posting of Vancouver science events features a description that resembles the one for the Liverpool Science Festival (from my posting),

There is a video of the Evan’s February 20, 2013 talk here for anyone who can’t get to Evans’ talk in Liverpool.

Here’s more from the Liverpool Science Festival announcement,

For the last highlight from the festival announcement, we return to physics,

“Mind-blowing.” – New York Times on Particle Fever

Screening of Particle Fever – Liverpool Science Festival has special permission to screen this new movie on CERN and the hunt for the Higgs Boson, three months ahead of its UK general release. The screening will be followed by a Q&A featuring Professor Tara Shears, CERN particle physicist and the University of Liverpool’s first ever female professor of physics. The screening takes place on the evening of 5 July at Stanley Dock.

www.liverpoolsciencefestival.com/particle-fever

“Particle Fever” received its May 16, 2014 Canadian premiere in Vancouver, which included a discussion with a panel of physicists.  (There was a also a showing when the Vancouver International Film Festival was held in Oct. 2013 and that has a separate webpage description. I assume a showing during a film festival is not considered a premiere) Here’s a description of the documentary from the Vancouver International Film Festival theatre’s Particle Fever webpage,

May 16th, 7:00 PM screening will be followed by a panel discussion of physicists, copresented by TRIUMF and supported by Reel Causes.
May 19th, 6:30 PM screening is open to youth, the film is rated PG

Imagine being able to watch as Edison turned on the first light bulb, or as Franklin received his first jolt of electricity. Physicist turned filmmaker Mark Levinson gives us the modern equivalent of those world-changing moments with this as-it-happens front-row seat to our generation’s most significant and inspiring scientific breakthrough—the launch of the Large Hadron Collider, near Geneva, built to recreate conditions that existed just moments after the Big Bang and to potentially explain the origin of all matter. Following a team of brilliant scientists, Levinson—aided by master editor Walter Murch—crafts a celebration of discovery while revealing the very human stories behind this epic machine.

“Set in crummy offices and towering facilities worthy of a Bond movie, the documentary is edited with the momentum of a thriller by the great Walter Murch (Apocalypse Now), as we follow six scientists. They come across as simultaneously passionate thinkers and endearing nerds: There’s the elegant Italian physicist and classical pianist Fabiola Gianotti, obliviously stepping into traffic while talking excitedly on her phone. Or postdoc student and experimental physicist Monica Dunford, declaring effusively: “It’s unbelievably fantastic how great data is.”

There is a Particle Fever May 14, 2014 review by Ken Eisner in the Vancouver local publication, The Georgia Straight.  Peculiarly and in the midst a poetic movie review, Eisner starts complaining about physics funding in the US,

In the rarefied world of quantum physics, “The ability to leap from failure to failure with undiminished enthusiasm is the key to success.” This is according to one scientist prominently featured in an absorbing doc that takes as its locus the Large Hadron Collider, in Switzerland, where some pretty amazing breakthroughs—and a few duds—have happened in the past few years.

The subtext is the struggle to keep pure learning alive with no promise of tangible return, except the possibility of knowledge that will forever alter our understanding of life. …

…

… its main activities take place at the huge site of CERN, near Lake Geneva—built there largely because right-wingers have managed to kill off nonprofit science in the U.S. [emphasis mine] Its hivelike realities, with staff drawn from a hundred nations, make it resemble a space station on Earth. …

I think there may have been a few other important  factors influencing the Large Hadron Collider’s location.

Getting back to Liverpool, if the website is any indication, this science festival has been beautifully conceptualized and thoughtfully implemented. I wish the organizers all the best as they get ready to launch their festival.

Finally, in the description of the Hitchhiker’s Guide to the Solar System event, I noticed a reference to the Mersey, which brought to mind this song from 1965. Gerry & the Pacemakers sing Ferry Cross the Mersey,

Peter Higgs and François Englert to receive 2013 Nobel Prize in Physics and TRIUMF name changes?

2 Replies

After all the foofaraw about finding/confirming the existence of the Higgs Boson or ‘god’ particle (featured in my July 4, 2012 posting amongst many others), the Royal Swedish Academy of Sciences has decided to award the 2013 Nobel prize for Physics to two of the individuals responsible for much of the current thinking about subatomic particles and mass (from the Oct. 8, 2013 news item on ScienceDaily),

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2013 to François Englert of Université Libre de Bruxelles, Brussels, Belgium, and Peter W. Higgs of the University of Edinburgh, UK, “for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN’s Large Hadron Collider.”

François Englert and Peter W. Higgs are jointly awarded the Nobel Prize in Physics 2013 for the theory of how particles acquire mass. In 1964, they proposed the theory independently of each other (Englert together with his now deceased colleague Robert Brout). In 2012, their ideas were confirmed by the discovery of a so called Higgs particle at the CERN laboratory outside Geneva in Switzerland.

TRIUMF, sometimes known as Canada’s national laboratory for particle and nuclear physics, has issued an Oct. 8, 2013 news release,

HIGGS, ENGLERT SHARE 2013 NOBEL PRIZE IN PHYSICS

Canadians Key Part of Historical Nobel Prize to “Godfathers” of the “God Particle”

(Vancouver, BC) — The Royal Swedish Academy of Sciences today awarded the Nobel Prize in physics to Professor Peter W. Higgs (Univ. of Edinburgh) and Professor François Englert (Univ. Libre de Bruxelles) to recognize their work developing the theory of what is now known as the Higgs field, which gives elementary particles mass.  Canadians have played critical roles in all stages of the breakthrough discovery Higgs boson particle that validates the original theoretical framework.  Throngs across Canada are celebrating.

More than 150 Canadian scientists and students at 10 different institutions are presently involved in the global ATLAS experiment at CERN.  Canada’s national laboratory for particle and nuclear physics, TRIUMF, has been a focal point for much of the Canadian involvement that has ranged from assisting with the construction of the LHC accelerator to building key elements of the ATLAS detector and hosting one of the ten global Tier-1 Data Centres that stores and processes the physics for the team of thousands.

“The observation of a Higgs Boson at about 125 GeV, or 130 times the mass of the proton, by both the ATLAS and CMS groups is a tremendous achievement,” said Rob McPherson, spokesperson of the ATLAS Canada collaboration, a professor of physics at the University of Victoria and Institute of Particle Physics scientist. “Its existence was predicted in 1964 when theorists reconciled how massive particles came into being.  It took almost half a century to confirm the detailed predictions of the theories in a succession of experiments, and finally to discover the Higgs Boson itself using our 2012 data.”

The Brout-Englert-Higgs (BEH) mechanism was first proposed in 1964 in two papers published independently, the first by Belgian physicists Robert Brout and François Englert, and the second by British physicist Peter Higgs. It explains how the force responsible for beta decay is much weaker than electromagnetism, but is better known as the mechanism that endows fundamental particles with mass. A third paper, published by Americans Gerald Guralnik and Carl Hagen with their British colleague Tom Kibble further contributed to the development of the new idea, which now forms an essential part of the Standard Model of particle physics. As was pointed out by Higgs, a key prediction of the idea is the existence of a massive boson of a new type, which was discovered by the ATLAS and CMS experiments at CERN in 2012.

The next step will be to determine the precise nature of the Higgs particle and its significance for our understanding of the universe. Are its properties as expected for the Higgs boson predicted by the Standard Model of particle physics? Or is it something more exotic? The Standard Model describes the fundamental particles from which we, and every visible thing
in the universe, are made, and the forces acting between them. All the matter that we can see, however, appears to be no more than about 4% of the total. A more exotic version of the Higgs particle could be a bridge to understanding the 96% of the universe that remains obscure.

TRIUMF salutes Peter Higgs and François Englert for their groundbreaking work recognized by today’s Nobel Prize and congratulates the international team of tens of thousands of scientists, engineers, students, and many more from around the world who helped make the discovery.

While I know Canadians have been part of the multi-year, multi-country effort to determine the existence or non-existence of the Higgs Boson and much more in the field of particle physics, I would prefer we were not described as “… Key Part of Historical Nobel Prize … .” The question that springs to mind is: how were Canadian efforts key to this work? The answer is not revealed in the news release, which suggests that the claim may be a little overstated. On the other hand, I do like the bit about ‘saluting Higgs and Englert for their groundbreaking work’.

As for TRIUMF and what appears to be a series of name changes, I’m left somewhat puzzled, This Oct. 8, 2013 news release bears the name (or perhaps it’s a motto or tagline of some sort?): TRIUMF — Accelerating Science for Canada, meanwhile the website still sports this: TRIUMF Canada’s national laboratory for particle and nuclear physics while a July 17, 2013 TRIUMF news release gloried in this name: TRIUMF Accelerators, Inc., (noted in my July 18, 2013 posting). Perhaps TRIUMF is trying to follow in CERN’s footsteps. CERN was once known as the ‘European particle physics laboratory’ but is now known as the European Organization for Nuclear Research and seems to also have the tagline: ‘Accelerating science’.

Pulling the trigger on the Higgs—Vancouver’s (Canada) Sept. 25, 2012 Café Scientifique

Leave a reply

Dr. Isabel Trigger, from TRIUMF (Canada’s national laboratory for particle and nuclear physics laboratory), will be presenting at Vancouver’s next Café Scientifique event on Tuesday, Sept. 25, 2012 at 7:30 pm in the Railway Club, 579 Dunsmuir St. (at Seymour St.) in downtown Vancouver.

From the Sept, 18, 2012 event announcement,

The title and abstract for her [Isabel Trigger] café is:

Higgs for the Masses : a peek under the hood of the universe

This summer experiments at the world’s largest particle accelerator at the CERN laboratory in Geneva announced discovery of a subatomic particle “consistent” with the one  believed to give matter its mass.  The Higgs Boson sparked extraordinary levels of public attention and media interest, in part due to the particle’s nickname (“god particle”), but also since its  discovery is the result of  a 40-year quest involving tens of thousands of scientists.   But what, exactly, is a Higgs Boson? Why is it important? Who found it, and how?  And what do we do with it now that we think we’ve found it? This talk will explore the Higgs Boson and what it means for our understanding of the universe at its most basic level.

I think it helps to know a little more about Trigger (from her biography page on the TRIUMF website),

Isabel Trigger graduated with a B.Sc. from McGill in 1994 and went on to complete an M.Sc. and a Ph.D. at the Université de Montréal between 1994 and 1999. Her M.Sc. thesis, “Evolution du spectre de dépôts énergétiques dans les détecteurs au silicium irradiés en protons,” studied the ultimate performance of silicon-based precise tracking detectors in the presence of radiation for the LHC. Her Ph.D., “Mesure des couplages trilinéaires anomaux des bosons de jauge avec le détecteur OPAL au LEP,” included definitive measurements of the self-coupling of standard model gauge bosons and is considered one of most challenging experimental analyses performed at the Large Electron Positron (LEP) Collider.

Dr. Trigger was awarded the competitive CERN Research Fellowship in 1999, leading to the exceptionally rare offer of a CERN research staff position in 2001. She personally performed the most general and comprehensive search for the “chargino” particles predicted by supersymmetric theories.

Isabel was also a leader in the CERN [European Particle Physics Laboratory] team designing and testing the alignment system that monitors the relative positions of the 22 m diameter ATLAS endcap muon chambers with 50 μm [micrometre] accuracy. In 2005, TRIUMF recruited Dr. Trigger to lead the establishment of an ATLAS physics analysis group. She is currently the ATLAS-Canada physics coordinator.

From what I understand they are now declaring the Higgs boson exists when I last reported (my July 4, 2012 posting) on this topic, scientists at CERN were pretty sure it existed. I’m sure Trigger will have the latest information.

On a completely other note, I think café  is a bit of a misnomer for the Vancouver events held at the Railway Club, since this is a beer drinking establishment. So, be prepared to drink beer in a back room on Tuesday night (Sept. 25) while you listen to talk about the underpinnings of the universe.

Playing and singing the Higgs Boson

Leave a reply

The Higgs Boson has lead to an explosion of creativity. First, the Guerilla Science team has produced a Secret Garden Party (July 19 – 22, 2012) featuring the Higgs Boson. Here’s a video clip from the 2012 event,

Zoe Cormier (writer and Guerilla Science co-founder) notes in her July 27, 2012 posting on the Guardian science blogs,

The Particle Zoo Safari, hosted by Guerilla Science at the Secret Garden Party arts and music festival last weekend, observed the formation of another proton and hydrogen atom, the sparring of two combative electrons, polyamorous covalent bond formation, sunlight manufacture through fusion (and a ping pong ball), and the creation of deuterium – complete with dubstep to mirror the atomic weight of the heavy form of hydrogen.

With polystyrene magnets our audience-cum-collider recreated the Large Hadron Collider (LHC) to produce the star of the show: the Higgs boson, sumo-suited and angry, the weightiest particle of all. “I’m hungry,” it grumpily announced, before we threw a net over it and dragged it into the tent. Too much had been spent on the particle’s discovery to let it escape now.

“The idea of the safari came from a colloquialism in physics, which refers to the set of standard particles that make up the entire universe as the ‘particle zoo’,” explains Patrick Stevenson-Keating, the designer we enlisted to help us devise a new way to explore particle physics. “This scale of subatomic particles is so different to our everyday world that there are few comparisons you can really make, so it was challenging to visualise some of the concepts.”

Here’s what the science consultant had to say about it (from Cormier’s posting),

“When I was first approached to take part, I did think it sounded a bit nuts actually, but in the end it worked out reasonably well in terms of the science – I think most people would at least remember that quarks come in threes, and they are difficult to pull apart,” says Dr James Monk of the University College London, a particle physicist who works on the Atlas experiment on the LHC, whom we enlisted as a scientific consultant. “These particles and forces are important to understand how the world works, and it wouldn’t be fitting if physicists said that we do all this fantastic research – but the rest of you can’t possibly understand it.”

It’s well worth reading Cormier’s whole post and you might even feel like taking another look at the video (I found it embedded in Cormier’s posting)  after reading.

(Last year, I featured Guerilla Science and Cormier in my July 12, 2011 posting.)

Meanwhile, the Higgs is producing music. According to David Bruggeman’s July 28, 2012 posting on his Pasco Phronesis blog,

While it seems unlikely that papers will soon come as .mp3 files with audio infographics, some are still working on hearing things we usually expect to see.

…

The idea is to match energy levels found in the data with particular notes.  That way shifts in energy can be more immediately expressed as shifts in tone.  The Higgs boson peaks out of the background noise – noise that isn’t really noise from a musical perspective.

David is hoping turning data into music could be used in the future for educational purposes,

… for those who have an easier time detecting patterns in audio rather than printed data, this could be a very productive development.

I thought it would be interesting to hear some Higgs Boson music. While this piece is based on Higgs data, the composer has taken liberties after letting you hear what the untreated melody sounds like,

The composer, Ben McCormack, had this to say about the piece titled, Higgs Boson (ATLAS preliminary data),

The data was already converted to notes by Domenico Vicinanza. I then consolidated the melody to remove a lot of the large leaps, giving it a slightly better flow.

Before you say anything, I know that this (at least somewhat) defeats the purpose of the data. I’m a composer; my goal was primarily to make a fun piece of music. I inverted the melody and wrote countermelodies that aren’t mathematically-related to the original melody, so consider this more a creative work than an exercise in data analysis.

You can find out more about the Higgs Boson in my July 4, 2012 posting where I wrote about the then latest announcement from CERN (European Particle Physics Laboratory).
