Movies and science, science, science (Part 2 of 2)

Part 1 concerned the soon-to-be-released movie, Hidden Figures and a film which has yet to start production, Photograph 51 (about Rosalind Franklin and the discovery of the double helix structure DNA [deoxyribonucleic acid]). Now for Part 2:

A matter of blood, Theranos, and Elizabeth Holmes

A few months ago, a friend asked me if I’d heard of Theranos. Given that I have featured various kinds of cutting edge diagnostic tests here, it was a fair enough question. Some  of my first questions to her were about the science. My friend had read about the situation in The Economist where the focus of the story (which I later read) was about venture capital. I got back to my friend and said that if they hadn’t published any scientific papers, I most likely would not have stumbled across them. Since then I’ve heard much more about Theranos but it seems there’s not much scientific information to be had from the company.

Reportedly, US film star Jennifer Lawrence is set to star, from a June 10, 2016 posting by Lainey (at Lainey Gossip; Note: A link has been removed),

Deadline reported yesterday [June 9, 2016] that Jennifer Lawrence will star in Adam McKay’s upcoming film about Elizabeth Holmes and Theranos. Elizabeth Holmes was basically the Jennifer Lawrence of Silicon Valley after inventing what she claimed to be a revolutionary blood testing system. Instead of submitting full vials of blood for limited testing, her product promised more efficiency and quicker results with just a pinprick. You can imagine how that would change the health care industry.

Last year, The Wall Street Journal investigated the viability of Theranos’s business plan, exposing major problems in the company’s infrastructure. Elizabeth Holmes went from being called the world’s youngest self-made female billionaire, the millennial in a turtleneck, to a possible fraud. It’s a fascinating story. …

In a July 16, 2016 article The Economist provides an update to the evolving Theranos/Holmes story,

FIRST they think you’re crazy, then they fight you, and then all of the sudden you change the world,” said Elizabeth Holmes as troubles mounted for her blood-testing startup, Theranos, last year. Things look ever less likely to go beyond the fighting stage.

On July 7th [2016] a government regulator, the Centres for Medicare and Medicaid Services, said Ms Holmes would be barred from owning or running a laboratory for two years. It will also revoke her company’s licence to operate one of two laboratories where it conducts tests. As The Economist went to press the firm was due to reply to a letter from Congress, which asked how, exactly, Theranos is going to handle the tens of thousands of patients who were given incorrect test results. Even so, Ms Holmes looks set to remain in position even as the situation deteriorates around a firm that once commanded a multi-billion-dollar valuation.

These may be some of the last twists in a story which will be turned into a Hollywood film by the director of “The Big Short”.

For anyone wondering how a movie could be made when the story has come to any kind of resolution, there’s this from a June 24, 2016 posting by David Bruggeman for his Pasco Phronesis blog (Note: Links have been removed),

Since last I wrote about a possible film about the medical device/testing company Theranos, a studio has successfully bid on the project.  Legendary Studios won an auction on the film rights, beating out 9 other offers on the project, which has Jennifer Lawrence attached to star as Theranos CEO Elizabeth Holmes.  Adam McKay would write the script and direct the project, duplicating his roles on the Oscar-nominated film The Big Short.  The film now has a preliminary title of Bad Blood.  It is certainly too early to tell if the Taylor Swift song of the same name will be used in the movie.

While getting a studio offer is important to the film getting produced, what is perhaps as interesting to our readers is that a book is connected to the film deal.  Two-time Pulitzer-prize winning writer John Carreyrou, who has written extensively on Theranos in The Wall Street Journal, will be writing a book that (presumably) serves as the basis for the script.  This follows the development arc for The Big Short, for which McKay shares an Adapted Screenplay Oscar (in addition to his nomination for directing the film)

So, are they going to wait until Holmes is either finally vindicated or vilified before going to film? Meanwhile, Holmes continues in a quest to save her company (from an Aug. 1, 2016 article for Fast Company by Christina Farr titled: Scientists Wanted Transparency From Theranos, But Got A Product Launch Instead (Note: A link has been removed),

Theranos once promised to revolutionize the blood testing industry. But its methodology remains secretive, despite calls for transparency from the scientific community. Now, it is facing federal investigations, private litigation, voided tests, and its CEO, Elizabeth Holmes, is banned from operating a lab for two years.

But all that was entirely glossed over today at the company’s much-awaited first presentation to the scientific community at the American Association for Clinical Chemistry’s conference in Philadelphia.

In an hour-long presentation (you can review the slides here), Holmes failed to discuss the fate of the company’s proprietary blood-testing technology, Edison, or address any of the controversy. Instead, she skipped right to pitching a new product, dubbed the MiniLab.

In fairness to Theranos, this was a positive step as the company did provide some internal data to show that the company could perform a small number of tests. But despite that, many took to social media to protest its failure to address and acknowledge its shortcomings before moving on to a new product.

“Clearly, the scientific and medical community was hoping for a data-driven discussion today, and instead got a new product announcement,” says John Torous, a psychiatrist and clinical informatics fellow at Harvard Medical School.

In an emailed response to Fast Company, a Theranos company spokesperson did not say whether components of Edison would be used in the miniLAB, but instead stressed that it’s one early iteration of the technology. “The miniLab is the latest iteration of the company’s testing platform and an evolution of Theranos’ technology,” they said.

Farr describes the MiniLab and notes that it is entering a competitive market,

The new product, the MiniLab, essentially takes equipment used in a standard lab and puts it in a single box. Holmes refers to this technique as “decentralizing the lab,” as in theory, clinicians could use this as an alternative to sending samples to a centralized facility and awaiting results. “Think of it as being a huge diagnostics lab that has been condensed down to the size of a microwave,” the company’s website explains.


But scientists are questioning whether the MiniLab technology is a breakthrough. The current market is already fairly saturated: Abbott’s iStat system, for instance, is a handheld device for clinicians to test patients for a plethora of common tests. Roche just received FDA [US Food and Drug Administration] clearance for its Cobas device, which can test for ailments like the flu and some strep infections in under 20 minutes. And Theranos competitors Quest and Labcorp already operate versions of this type of equipment in their own labs.

“I can’t imagine why they’re wasting their time,” says MIT-trained material scientist and biotech entrepreneur Kaveh Milaninia by phone. …

I recommend reading Farr’s article in its entirety as she provides more detail and analysis as to just how competitive the market Theranos proposes entering with its MiniLab actually is.

An Aug. 31, 2016 article by Lydia Ramsey for Slate.com the most recent update on the Theranos situation,

Theranos is withdrawing its bid for FDA approval of a diagnostic test for Zika that they announced earlier in August, according to a story in the Wall Street Journal.

Theranos confirmed to Business Insider that the test has been withdrawn, but said the company has plans to resubmit it.

John Carreyrou and Christopher Weaver report that an FDA inspection found that, as part of a study to validate the new test, the company had collected some data without a patient safety plan in place that was approved by an institutional review board.

“We hope that our decision to withdraw the Zika submission voluntarily is further evidence of our commitment to engage positively with the agency. We are confident in the Zika tests and will resubmit it,” Theranos vice president of regulatory and quality Dave Wurtz said in a statement emailed to Business Insider. Wurtz joined the company in July [2016].

Getting back to the point of my story at the beginning of this piece, it seems that Theranos and Elizabeth Holmes have not been as forthcoming with scientific data as is common in the biotech field. Interestingly, I read somewhere that the top 10 venture capitalists in the biotech field had not invested a penny in Theranos. The money had come from venture capitalists expert in other fields. (If you can confirm or know differently, please let me know in the comments section.)

In its favour, the company does appear to be attempting to address its shortcomings.

*ETA Oct. 6, 2016: Theranos is closing down some of its labs according to an Oct. 6, 2016 news item on phys.org,

Theranos, a onetime star Silicon Valley startup focused on health technology, is closing its consumer blood-testing facilities amid its struggles with US regulators.

The company, which has been seeking to disrupt the medical testing sector with new technology, said the closings will mean cutting some 340 jobs.

“After many months spent assessing our strengths and addressing our weaknesses, we have moved to structure our company around the model best aligned with our core values and mission,” company founder Elizabeth Holmes said in an open letter.

Theranos, which touts a new way of testing that uses far less blood and delivers faster results at much lower cost than traditional methods in US labs, has been under civil and criminal investigation over its claims.

Holmes said the company would focus on a so-called miniLab which can be commercialized with partners.

Things don’t look good.*

In any event, all these goings on should make for an interesting script writing challenge.

Bits and bobs of science and movies (The Man Who Knew Infinity, Ghostbusters, and Imagine Science Films)

The Man Who Knew Infinity had its debut at the 2015 Toronto International Film Festival. I haven’t seen it at any movie houses here (Vancouver, Canada) yet but a film trailer featuring its star, Dev Patel, was released in Feb. 2016,

Ramanujan must have been quite the mathematician, given the tenor of the times. Here’s more about the movie from its Wikipedia entry (Note: Links have been removed),

The Man Who Knew Infinity is a 2015 British biographical drama film based on the 1991 book of the same name by Robert Kanigel. The film stars Dev Patel as the real-life Srinivasa Ramanujan, a mathematician who after growing up poor in Madras, India, earns admittance to Cambridge University during World War I, where he becomes a pioneer in mathematical theories with the guidance of his professor, G. H. Hardy (played by Jeremy Irons despite Hardy being only 10 years older than Ramanujan).

Filming began in August 2014 at Trinity College, Cambridge.[4] The film had its world premiere as a gala presentation at the 2015 Toronto International Film Festival,[1][5] and was selected as the opening gala of the 2015 Zurich Film Festival.[6] It also played other film festivals including Singapore International Film Festival[7] and Dubai International Film Festival.[8]

Distinguished mathematicians Manjul Bhargava and Ken Ono are Associate Producers of the film.[9] Ono, the mathematics consultant, is a Guggenheim Fellow, and Bhargava is a winner of the Fields Medal.

Next up, Ghostbusters, the all woman edition. While it hasn’t become the blockbuster some were hoping for, I have some hope that it will become a quiet blockbuster over time. As I wait there is this information about how Ghostbuster: The All Woman Edition was grounded in real science. From a July 18, 2016 news item on phys.org,

Janet Conrad and Lindley Winslow, colleagues in the MIT [Massachusetts Institute of Technology] Department of Physics and researchers in MIT’s Lab for Nuclear Science, were key consultants for the all-female reboot of the classic 1984 supernatural comedy that is opening in theaters today. And the creative side of the STEM fields—science, technology, engineering, and mathematics—will be on full display.

A July 16, 2016 MIT news release, which originated the news item expands on the theme (Note: Links have been removed),

Kristin Wiig’s character, Erin Gilbert, a no-nonsense physicist at Columbia University, is all the more convincing because of Conrad’s toys. Her office features demos and other actual trappings from Conrad’s workspace: books, posters, and scientific models. She even created detailed academic papers and grant applications for use as desk props.

“I loved the original ‘Ghostbusters,’” says Conrad. “And I thought the switch to four women, the girl-power concept, was a great way to change it up for the reboot. Plus I love all of the stuff in my office. I was happy to have my books become stars.”

Conrad developed an affection for MIT while absorbing another piece of pop culture: “Doonesbury.” She remembers one cartoon strip featuring a girl doing Psets. She is discouraged until a robot comes to her door and beeps. All is right with the world again. The exchange made an impression. “Only at MIT do robots come by your door to cheer you up,” she thought.

Like her colleague, Winslow describes mainstream role models as powerful, particularly when fantasy elements in film and television enhance their childhood appeal. She, too, loved “Ghostbusters” as a kid. “I watched the original many times,” she recalls. “And my sister had a stuffed Slimer.”

Winslow jokes that she “probably put in too much time” helping with the remake. Indeed, Wired magazine recently detailed that: “In one scene in the movie, Wiig’s Gilbert stands in front of a lecture hall, speaking on challenges of reconciling quantum mechanics with Einstein’s gravity. On the whiteboards, behind her, a series of equations tells the same story: a self-contained narrative, written by Winslow and later transcribed on set, illustrating the failure of a once-promising physics theory called SU(5).”

Movie reviewers have been floored by the level of set detail. Also deserving of serious credit is James Maxwell, a postdoc at the Lab for Nuclear Science during the period he worked on “Ghostbusters.” He is now a staff scientist at Thomas Jefferson National Accelerator Facility in Newport News, Virginia.

Maxwell crafted realistic schematics of how proton packs, ghost traps, and other paranormal equipment might work. “I recalled myself as a kid, poring over the technical schematics of X-wings and Star Destroyers. I wanted to be sure that boys and especially girls of today could pore over my schematics, plug the components into Wikipedia, and find out about real tools that experimental physicists use to study the workings of the universe.”

He too hopes this behind-the-scenes MIT link with a Hollywood blockbuster will get people thinking. “I hope that it shows a little bit of the giddy side of science and of MIT; the laughs that can come with a spectacular experimental failure or an unexpected break-through.”

The movie depicts the worlds of science and engineering, as drawn from MIT, with remarkable conviction, says Maxwell. “So much of the feel of the movie, and to a great degree the personalities of the characters, is conveyed by the props,” he says.

Kate McKinnon’s character, Jillian Holtzmann, an eccentric engineer, is nearly inseparable from, as Maxwell says, “a mess of wires and magnets and lasers” — a pile of equipment replicated from his MIT lab. When she talks proton packs, her lines are drawn from his work.

Keep an eye out for treasures hidden in the props. For instance, Wiig’s character is the recipient of the Maria Goeppert Mayer “MGM Award” from the American Physical Society, which hangs on her office wall. Conrad and Winslow say the honor holds a special place in their hearts.

“We both think MGM was inspirational. She did amazing things at a time when it was tough for women to do anything in physics,” says Conrad. “She is one of our favorite women in physics,” adds Winslow. Clearly, some of the film’s props and scientific details reflect their personal predilections but Hollywood — and the nation — is also getting a real taste of MIT.

Finally and strictly speaking not a movie but it is an online magazine about science-based movies according to David Bruggeman’s Aug. 6, 2016 posting on his Pasco Phronesis blog (Note: Links have been removed),

LaboCine is an online film magazine from the people behind Imagine Science Films.  The films in each issue come from artists and scientists from around the world.  They are not restricted to documentary films, and mix live-action, animated and computer film styles.

The first issue of LaboCine is now online, so you can view the short films, which are organized around a common theme.  For August the theme is Model Organisms. …

You find the LaboCine magazine here and Imagine Science Films here. Btw, Raewyn Turner (NZ artist) has submitted our filmpoem, Steep (1) : A digital poetry of gold nanoparticles to the 9th Imagine Science Festival to be held Oct. 14-21, 2016 in New York City.

And that is it!

Here’s Part 1 for those who missed it.

Movies and science, science, science (Part 1 of 2)

In the last few years, there’s been a veritable plethora of movies (and television shows in Canada and the US) that are about science and technology or have a significant  component or investigate the social impact. The trend does not seem to be slowing.

This first of two parts features the film, *Hidden* Figures, and a play being turned into a film, Photograph 51. The second part features the evolving Theranos story and plans to turn it into a film, The Man Who Knew Infinity, a film about an Indian mathematician, the science of the recent all woman Ghostbusters, and an ezine devoted to science films.

For the following movie tidbits, I have David Bruggeman to thank.

Hidden Figures

From David’s June 21, 2016 post on his Pasco Phronesis blog (Note: A link has been removed),

Hidden Figures is a fictionalized treatment of the book of the same name written by Margot Lee Shetterly (and underwritten by the Sloan Foundation).  Neither the book nor the film are released yet.  The book is scheduled for a September release, and the film currently has a January release date in the U.S.

Both the film and the book focus on the story of African American women who worked as computers for the government at the Langley National Aeronautic Laboratory in Hampton, Virginia.  The women served as human computers, making the calculations NASA needed during the Space Race.  While the book features four women, the film is focused on three: Katherine Johnson (recipient of the Presidential Medal of Freedom), Dorothy Vaughan, and Mary Jackson.  They are played by, respectively, Taraji P. Henson, Octavia Spencer, and Janelle Monae.  Other actors in the film include Kevin Costner, Kirsten Dunst, Aldis Hodge, and Jim Parsons.  The film is directed by Theodore Melfi, and the script is by Allison Schroeder.

*ETA Oct. 6, 2016: The book ‘Hidden Figures’ is nonfiction while the movie is a fictionalized adaptation  based on a true story.*

According to imdb.com, the movie’s release date is Dec. 25, 2016 (this could change again).

The history for ‘human computers’ stretches back to the 17th century, at least. From the Human Computer entry in Wikipedia (Note: Links have been removed),

The term “computer”, in use from the early 17th century (the first known written reference dates from 1613),[1] meant “one who computes”: a person performing mathematical calculations, before electronic computers became commercially available. “The human computer is supposed to be following fixed rules; he has no authority to deviate from them in any detail.” (Turing, 1950) Teams of people were frequently used to undertake long and often tedious calculations; the work was divided so that this could be done in parallel.

Prior to NASA, a team of women in the 19th century in the US were known as Harvard Computers (from the Wikipedia entry; Note: Links have been removed),

Edward Charles Pickering (director of the Harvard Observatory from 1877 to 1919) decided to hire women as skilled workers to process astronomical data. Among these women were Williamina Fleming, Annie Jump Cannon, Henrietta Swan Leavitt and Antonia Maury. This staff came to be known as “Pickering’s Harem” or, more respectfully, as the Harvard Computers.[1] This was an example of what has been identified as the “harem effect” in the history and sociology of science.

It seems that several factors contributed to Pickering’s decision to hire women instead of men. Among them was the fact that men were paid much more than women, so he could employ more staff with the same budget. This was relevant in a time when the amount of astronomical data was surpassing the capacity of the Observatories to process it.[2]

The first woman hired was Williamina Fleming, who was working as a maid for Pickering. It seems that Pickering was increasingly frustrated with his male assistants and declared that even his maid could do a better job. Apparently he was not mistaken, as Fleming undertook her assigned chores efficiently. When the Harvard Observatory received in 1886 a generous donation from the widow of Henry Draper, Pickering decided to hire more female staff and put Fleming in charge of them.[3]

While it’s not thrilling to find out that Pickering was content to exploit the women he was hiring, he deserves kudos for recognizing that women could do excellent work and acting on that recognition. When you consider the times, Pickering’s was an extraordinary act.

Getting back to Hidden Figures, an Aug.15, 2016 posting by Kathleen for Lainey Gossip celebrates the then newly released trailer for the movie,

If you’ve been watching the Olympics [Rio 2016], you know how much the past 10 days have been an epic display of #BlackGirlMagic. Fittingly, the trailer for Hidden Figures was released last night during Sunday’s Olympic coverage. It’s the story of three brilliant African American women, played by Taraji P Henson, Octavia Spencer and Janelle Monae, who made history by serving as the brains behind the NASA launch of astronaut John Glenn into orbit in 1962.

Three black women helped launch a dude into space in the 60s. AT NASA. Think about how America treated black women in the 60s. As Katherine Johnson, played by Taraji P Henson, jokes in the trailer, they were still sitting at the back of the bus. In 1962 Malcolm X said, “The most disrespected person in America is the Black woman, the most unprotected person in America is the Black woman. The most neglected person in America is the Black woman.” These women had to face that truth every day and they still rose to greatness. I’m obsessed with this story.

Overall, the trailer is good. I like the pace and the performances look strong. …

I’m most excited for Hidden Figures (as Lainey pointed out, this title is THE WORST) because black girls are being celebrated for their brains on screen. That is rare. When the trailer aired, my brother Sam texted me, “WHOA, a smart black girl movie!”

*ETA Sept. 5, 2016: Aran Shetterly contacted me to say this:

What you may not know is that the term “Hidden Figures” is a specific reference to flight science. It tested a pilot’s ability to pick out a simple figure from a set of more complex, difficult to see images. http://www.militaryaptitudetests.com/afoqt/

Thank you Mr. Shetterly!

Photograph 51 (the Rosalind Franklin story)

Also in David’s June 21, 2016 post is a mention of Photograph 51, a play and soon-to-be film about Rosalind Franklin, the discovery of the double helix, and a science controversy. I first wrote about Photograph 51 in a Jan. 16, 2012 posting (scroll down about 50% of the way) regarding an international script writing competition being held in Dublin, Ireland. At the time, I noted that Anna Ziegler’s play, Photograph 51 had won a previous competition cycle of the screenwriting competition. I wrote again about the play in a Sept. 2, 2015 posting about its London production (Sept. 5 – Nov. 21, 2015) featuring actress Nicole Kidman.

The versions of the Franklin story with which I’m familiar paint her as the wronged party, ignored and unacknowledged by the scientists (Francis, Crick, James Watson, and Maurice Wilkins) who got all the glory and the Nobel Prize. Stephen Curry in a Sept. 16, 2015 posting on the Guardian science blogs suggests the story may not be quite as simple as that (Note: A link has been removed),

Ziegler [Anna Ziegler, playwright] is up front in admitting that she has rearranged facts to suit the drama. This creates some oddities of chronology and motive for those familiar with the history. I know of no suggestion of romantic interest in Franklin from Wilkins, or of a separation of Crick from his wife in the aftermath of his triumph with Watson in solving the DNA structure. There is no mention in the play of the fact that Franklin published her work (and the famous photograph 51) in the journal Nature alongside Watson and Crick’s paper and one by Wilkins. Nor does the audience hear of the international recognition that Franklin enjoyed in her own right between 1953 and her untimely death in 1958, not just for her involvement in DNA, but also for her work on the structure of coal and of viruses.

Published long after her death, The Double Helix is widely thought to treat Franklin unfairly. In the minds of many she remains the wronged woman whose pioneering results were taken by others to solve DNA and win the Nobel prize. But the real story – many elements of which come across strongly in the play – is more complex*.

Franklin is a gifted experimentalist. Her key contributions to the discovery were in improving methods for taking X-ray pictures of and discovering the distinct A and B conformations of DNA. But it becomes clear that her methodical, meticulous approach to data analysis – much to Wilkins’ impotent frustration – eventually allows the Kings ‘team’ to be overtaken by the bolder, intuitive stratagem of Watson and Crick.

Curry’s piece is a good read and provides insight into the ways temperament affects how science is practiced.

Interestingly, there was a 1987 dramatization of the ‘double helix or life story’ (from the Life Story entry on Wikipedia; Note: Links have been removed),

The film tells the story of the rivalries of the two teams of scientists attempting to discover the structure of DNA. Francis Crick and James D. Watson at Cambridge University and Maurice Wilkins and Rosalind Franklin at King’s College London.

The film manages to convey the loneliness and competitiveness of scientific research but also educates the viewer as to how the structure of DNA was discovered. In particular, it explores the tension between the patient, dedicated laboratory work of Franklin and the sometimes uninformed intuitive leaps of Watson and Crick, all played against a background of institutional turf wars, personality conflicts and sexism. In the film Watson jokes, plugging the path of intuition: “Blessed are they who believed before there was any evidence.” The film also shows why Watson and Crick made their discovery, overtaking their competitors in part by reasoning from genetic function to predict chemical structure, thus helping to establish the then still-nascent field of molecular biology.

You can find out more about the stars, crew, and cast here on imdb.com

In addition to Life Story, the dramatization is also sometimes titled as ‘The Race for the Double Helix’ or the ‘Double Helix’.

Getting back to Photograph 51 (the film), Michael Grandage who directed the stage play will also direct the film. Grandage just made his debut as a film director with ‘Genius’ starring Colin Firth and Jude Law. According to this June 23, 2016 review by Sarah on Laineygossip.com, he stumbled a bit by casting British and Australian actors as Americans,

The first hurdle to clear with Genius, the feature film debut of English theater director Michael Grandage, is that everyone is played by Brits and Aussies, and by “everyone” I mean some of the most towering figures of American literature. You cast the best actor for the role and a good actor can convince you they’re anyone, so it shouldn’t really matter, but there is something profoundly odd about watching a parade of Lit 101 All Stars appear on screen and struggle with American accents. …

That kind of casting should not be a problem with Photograph 51 where the action takes place with British personalities.

Part 2 is here.

*’Human’ corrected to ‘Hidden’ on Sept. 5, 2016.

Ramanujan—a math genius who left behind math formulas that took 90 years to decode

1920, the year mathematician Srinivasa Ramanujan died, is also the year he left behind mathematical formulas that may help unlock the secrets of black holes (from the Dec. 11, 2012 posting by Carol Clark for Emory University’s e-science commons blog),

“No one was talking about black holes back in the 1920s when Ramanujan first came up with mock modular forms, and yet, his work may unlock secrets about them,” Ono [Emory University mathematician Ken Ono] says.

Expansion of modular forms is one of the fundamental tools for computing the entropy of a modular black hole. Some black holes, however, are not modular, but the new formula based on Ramanujan’s vision may allow physicists to compute their entropy as though they were.

Ramanujan was on his death bed (at the age of 32) when he devised his last formulas (from the Clark posting),

Accessed from http://esciencecommons.blogspot.ca/2012/12/math-formula-gives-new-glimpse-into.html

Accessed from http://esciencecommons.blogspot.ca/2012/12/math-formula-gives-new-glimpse-into.html

… A devout Hindu, Ramanujan said that his findings were divine, revealed to him in dreams by the goddess Namagiri.

While on his death-bed in 1920, Ramanujan wrote a letter to his mentor, English mathematician G. H. Hardy. The letter described several new functions that behaved differently from known theta functions, or modular forms, and yet closely mimicked them. Ramanujan conjectured that his mock modular forms corresponded to the ordinary modular forms earlier identified by Carl Jacobi, and that both would wind up with similar outputs for roots of 1.

No one at the time understood what Ramanujan was talking about. “It wasn’t until 2002, through the work of Sander Zwegers, that we had a description of the functions that Ramanujan was writing about in 1920,” Ono says.

This year (2012) a number of special events have been held to commemorate Ramanujan’s accomplishments (Note: I have removed links), from the Clark posting,

December 22 [2012] marks the 125th anniversary of the birth of Srinivasa Ramanujan, an Indian mathematician renowned for somehow intuiting extraordinary numerical patterns and connections without the use of proofs or modern mathematical tools. ..

“I wanted to do something special, in the spirit of Ramanujan, to mark the anniversary,” says Emory mathematician Ken Ono. “It’s fascinating to me to explore his writings and imagine how his brain may have worked. It’s like being a mathematical anthropologist.”

Ono, a number theorist whose work has previously uncovered hidden meanings in the notebooks of Ramanujan, set to work on the 125th-anniversary project with two colleagues and former students: Amanda Folsom, from Yale, and Rob Rhoades, from Stanford.

The result is a formula for mock modular forms that may prove useful to physicists who study black holes. The work, which Ono recently presented at the Ramanujan 125 conference at the University of Florida, also solves one of the greatest puzzles left behind by the enigmatic Indian genius.

Here’s a trailer for the forthcoming movie (a docu-drama) about Ramanujan, from the Clark posting,

Here’s a description of Ramanujan from Wikipedia, which gives some insight into the nature of his genius (Note: I have removed links and a footnote),

Srinivasa Ramanujan FRS (…) (22 December 1887 – 26 April 1920) was an Indian mathematician and autodidact who, with almost no formal training in pure mathematics, made extraordinary contributions to mathematical analysis, number theory, infinite series, and continued fractions. Living in India with no access to the larger mathematical community, which was centered in Europe at the time, Ramanujan developed his own mathematical research in isolation. As a result, he sometimes rediscovered known theorems in addition to producing new work. Ramanujan was said to be a natural genius by the English mathematician G.H. Hardy, in the same league as mathematicians like Euler and Gauss.

There is a little more to Ono’s latest work concerning Ramanujan’s deathbed math functions (from the Clark posting),

After coming up with the formula for computing a mock modular form, Ono wanted to put some icing on the cake for the 125th-anniversary celebration. He and Emory graduate students Michael Griffin and Larry Rolen revisited the paragraph in Ramanujan’s last letter that gave a vague description for how he arrived at the functions. That one paragraph has inspired hundreds of papers by mathematicians, who have pondered its hidden meaning for eight decades.

“So much of what Ramanujan offers comes from mysterious words and strange formulas that seem to defy mathematical sense,” Ono says. “Although we had a definition from 2002 for Ramanujan’s functions, it was still unclear how it related to Ramanujan’s awkward and imprecise definition.”

Ono and his students finally saw the meaning behind the puzzling paragraph, and a way to link it to the modern definition. “We developed a theorem that shows that the bizarre methodology he used to construct his examples is correct,” Ono says. “For the first time, we can prove that the exotic functions that Ramanujan conjured in his death-bed letter behave exactly as he said they would, in every case.”

Ono is now on a mathematicians’ tour in India (from the Clark posting),

Ono will spend much of December in India, taking overnight trains to Mysore, Bangalore, Chennai and New Dehli, as part of a group of distinguished mathematicians giving talks about Ramanujan in the lead-up to the anniversary date.

“Ramanujan is a hero in India so it’s kind of like a math rock tour,” Ono says, adding, “I’m his biggest fan. My professional life is inescapably intertwined with Ramanujan. Many of the mathematical objects that I think about so profoundly were anticipated by him. I’m so glad that he existed.”

Between this and the series developed by Alex Bellos about mathematics in Japan (my Oct. 17, 2012 posting), it seems that attention is turning eastward where the study and development of mathematics is concerned. H/T to EurekAlert’s Dec. 17, 2012 news release and do read Clark’s article if you want more information about Ono and Ramanujan.
