📅 The Calculus of Comedy: Math in The Simpsons, Futurama, and The Big Bang Theory at UCLA’s IPAM on 10/25

Bookmarked The Calculus of Comedy: Math in The Simpsons, Futurama, and The Big Bang Theory (IPAM (Special Events and Conferences))

When: Wednesday, October 25, 2017, from 4:30 PM – 6:30 PM PDT Where: UCLA California NanoSystems Institute (CNSI), 570 Westwood Plaza, Los Angeles, CA 90095 While there is no mathematical formula for writing television comedy, for the writers of The Simpsons, Futurama, and The Big Bang Theory, mathematical formulas (along with classic equations and cutting-edge theorems) can sometimes be an integral part of those shows. In a lively and nerdy discussion, five of these writers (who have advanced degrees in math, physics, and computer science) will share their love of numbers and talent for producing laughter. Mathematician Sarah Greenwald, who teaches and writes about math in popular culture, will moderate the panel. The event will begin with a lecture by bestselling author Simon Singh (The Simpsons and Their Mathematical Secrets), who will examine some of the mathematical nuggets hidden in The Simpsons (from Euler’s identity to Mersenne primes) and discuss how Futurama has also managed to include obscure number theory and complex ideas about geometry. Tickets: Tickets are $15 each and seating is limited, so reserve your seat soon. Tickets can be purchased here via Eventbrite (ticket required for entry to the event). A limited number of free tickets will be reserved for UCLA students. We ask that students come to IPAM between 9:00am and 3:00pm on Friday, October 20, to present your BruinCard and pick up your ticket (one ticket per BruinCard, nontransferable). If any tickets remain, we will continue distributing free tickets to students on Monday, Oct. 23, starting at 9:00am until we run out. Both your ticket and BruinCard must be presented at the door for entry. Doors open at 4:00. Please plan to arrive early to check in and find a seat. We expect a large audience.

Okay math nerds, this looks like an interesting lecture if you’re in Los Angeles next Wednesday. I remember reading and mostly liking Singh’s book The Simpsons and Their Mathematical Secrets a few years back.

The hard core math crowd may be disappointed in the level, but it could be an interesting group to get out and be social with.

My review of The Simpsons and Their Mathematical Secrets from Goodreads:

I’m both a math junkie and fan of the Simpsons. Singh’s book is generally excellent and well written and covers a broad range of mathematical areas. I’m a major fan of his book Big Bang: The Origin of the Universe, but find myself wanting much more from this effort. Much of my problem stems from my very deep knowledge of math and its history as well as having read most of the vignettes covered here in other general popular texts multiple times. Fortunately most readers won’t suffer from this and will hopefully find some interesting tidbits both about the Simpsons and math here to whet their appetites.

There were several spots at which I felt that Singh stretched a bit too far in attempting to tie the Simpsons to “mathematics” and possibly worse, several spots where he took deliberate detours into tangential subjects that had absolutely no relation to the Simpsons, but these are ultimately good for the broader public reading what may be the only math-related book they pick up this decade.

This could be considered a modern-day version of E.T. Bell‘s Men of Mathematics but with an overly healthy dose of side-entertainment via the Simpsons and Futurama to help the medicine go down.

📺 The Decentralized Social Web by Keith J. Grant

Bookmarked The Decentralized Social Web by Keith J. Grant (Recall Act)

We tend to have a love/hate relationship with social networks. The ability to interact with friends, colleagues, and even celebrities is wonderful, but the lack of control over privacy or content algorithms is troubling. A better way lies ahead, where you aren't tied to large social networks and where you can own your own data. Recorded at Atlanta Connect.Tech 2017 on 9/21/2017

A few weeks back Keith gave a great non-platform specific overview to some of the moving pieces of the IndieWeb at Connect.Tech 2017 in Atlanta. I wish I could have been there in person, but glad that it was archived on video for posterity.

Somehow I managed to get a mention in his talk as did our friend Jeremy Cherfas.

The slides for his talk are archived, naturally, on his own website.

🔖 Origin: A Novel by Dan Brown

Bookmarked Origin: A Novel by Dan Brown (Doubleday)

Robert Langdon, Harvard professor of symbology and religious iconology, arrives at the ultramodern Guggenheim Museum Bilbao to attend a major announcement—the unveiling of a discovery that “will change the face of science forever.” The evening’s host is Edmond Kirsch, a forty-year-old billionaire and futurist whose dazzling high-tech inventions and audacious predictions have made him a renowned global figure. Kirsch, who was one of Langdon’s first students at Harvard two decades earlier, is about to reveal an astonishing breakthrough . . . one that will answer two of the fundamental questions of human existence.

As the event begins, Langdon and several hundred guests find themselves captivated by an utterly original presentation, which Langdon realizes will be far more controversial than he ever imagined. But the meticulously orchestrated evening suddenly erupts into chaos, and Kirsch’s precious discovery teeters on the brink of being lost forever. Reeling and facing an imminent threat, Langdon is forced into a desperate bid to escape Bilbao. With him is Ambra Vidal, the elegant museum director who worked with Kirsch to stage the provocative event. Together they flee to Barcelona on a perilous quest to locate a cryptic password that will unlock Kirsch’s secret.

Navigating the dark corridors of hidden history and extreme religion, Langdon and Vidal must evade a tormented enemy whose all-knowing power seems to emanate from Spain’s Royal Palace itself . . . and who will stop at nothing to silence Edmond Kirsch. On a trail marked by modern art and enigmatic symbols, Langdon and Vidal uncover clues that ultimately bring them face-to-face with Kirsch’s shocking discovery . . . and the breathtaking truth that has long eluded us.

🔖 Stamp for music playlist portability

Bookmarked Stamp | FREE YOUR MUSIC (Stamp)

Stamp moves tracks and playlists across various services - Apple Music, Spotify, Google Music and others!

How awesome this portends to be! I’ve been wanting this type of functionality for a long time. I’m curious how long it stays up?

Too many music services don’t make it easy to transport your playlists as it’s one of the methods they use to lock you into their service (and their recurring subscription fees). It looks like it supports .csv formats, but it would be nice if there were a better standardized data format to let users own all of their own data. How great would it be if I could maintain my own playlist on my own website and then authorize services to access it to play what I wanted? Then I could have one central repository and take it to any subscription service out there.

It looks like it supports Spotify, Apple Music, Google Music, Pandora (Pro only?), Amazon Music, Groove, YouTube, rdio, Deezer, and Tidal.

🔖 Upcoming Special Issue “Information Theory in Neuroscience” | Entropy (MDPI)

Bookmarked Special Issue "Information Theory in Neuroscience" (Entropy | MDPI)

As the ultimate information processing device, the brain naturally lends itself to be studied with information theory. Application of information theory to neuroscience has spurred the development of principled theories of brain function, has led to advances in the study of consciousness, and to the development of analytical techniques to crack the neural code, that is to unveil the language used by neurons to encode and process information. In particular, advances in experimental techniques enabling precise recording and manipulation of neural activity on a large scale now enable for the first time the precise formulation and the quantitative test of hypotheses about how the brain encodes and transmits across areas the information used for specific functions. This Special Issue emphasizes contributions on novel approaches in neuroscience using information theory, and on the development of new information theoretic results inspired by problems in neuroscience. Research work at the interface of neuroscience, Information Theory and other disciplines is also welcome. A special issue of Entropy (ISSN 1099-4300). This special issue belongs to the section "Information Theory". Deadline for manuscript submissions: 1 December 2017

🔖 Back to the Future: The Decentralized Web, a report by Digital Currency Initiative & Center for Civic Media

Bookmarked Back to the Future: The Decentralized Web, A report by the Digital Currency Initiative and the Center for Civic Media (Digital Currency Initiative / MIT Media Lab)

The Web is a key space for civic debate and the current battleground for protecting freedom of expression. However, since its development, the Web has steadily evolved into an ecosystem of large, corporate-controlled mega-platforms which intermediate speech online. In many ways this has been a positive development; these platforms improved usability and enabled billions of people to publish and discover content without having to become experts on the Web’s intricate protocols. But in other ways this development is alarming. Just a few large platforms drive most traffic to online news sources in the U.S., and thus have enormous influence over what sources of information the public consumes on a daily basis. The existence of these consolidated points of control is troubling for many reasons. A small number of stakeholders end up having outsized influence over the content the public can create and consume. This leads to problems ranging from censorship at the behest of national governments to more subtle, perhaps even unintentional, bias in the curation of content users see based on opaque, unaudited curation algorithms. The platforms that host our networked public sphere and inform us about the world are unelected, unaccountable, and often impossible to audit or oversee. At the same time, there is growing excitement around the area of decentralized systems, which have grown in prominence over the past decade thanks to the popularity of the cryptocurrency Bitcoin. Bitcoin is a payment system that has no central points of control, and uses a novel peer-to-peer network protocol to agree on a distributed ledger of transactions, the blockchain. Bitcoin paints a picture of a world where untrusted networks of computers can coordinate to provide important infrastructure, like verifiable identity and distributed storage. Advocates of these decentralized systems propose related technology as the way forward to “re-decentralize” the Web, by shifting publishing and discovery out of the hands of a few corporations, and back into the hands of users. These types of code-based, structural interventions are appealing because in theory, they are less corruptible and resistant to corporate or political regulation. Surprisingly, low-level, decentralized systems don’t necessarily translate into decreased market consolidation around user-facing mega-platforms. In this report, we explore two important ways structurally decentralized systems could help address the risks of mega-platform consolidation: First, these systems can help users directly publish and discover content directly, without intermediaries, and thus without censorship. All of the systems we evaluate advertise censorship-resistance as a major benefit. Second, these systems could indirectly enable greater competition and user choice, by lowering the barrier to entry for new platforms. As it stands, it is difficult for users to switch between platforms (they must recreate all their data when moving to a new service) and most mega-platforms do not interoperate, so switching means leaving behind your social network. Some systems we evaluate directly address the issues of data portability and interoperability in an effort to support greater competition.

Bookmarked SFI and ASU to offer online M.S. in Complexity (Complexity Explorer)

SFI and Arizona State University soon will offer the world’s first comprehensive online master’s degree in complexity science. It will be the Institute’s first graduate degree program, a vision that dates to SFI’s founding. “With technology, a growing recognition of the value of online education, widespread acceptance of complexity science, and in partnership with ASU, we are now able to offer the world a degree in the field we helped invent,” says SFI President David Krakauer, “and it will be taught by the very people who built it into a legitimate domain of scholarship.”

🔖 Elementary Algebraic Geometry by Klaus Hulek

Bookmarked Elementary Algebraic Geometry (Student Mathematical Library, Vol. 20) (American Mathematical Society)

This is a genuine introduction to algebraic geometry. The author makes no assumption that readers know more than can be expected of a good undergraduate. He introduces fundamental concepts in a way that enables students to move on to a more advanced book or course that relies more heavily on commutative algebra. The language is purposefully kept on an elementary level, avoiding sheaf theory and cohomology theory. The introduction of new algebraic concepts is always motivated by a discussion of the corresponding geometric ideas. The main point of the book is to illustrate the interplay between abstract theory and specific examples. The book contains numerous problems that illustrate the general theory. The text is suitable for advanced undergraduates and beginning graduate students. It contains sufficient material for a one-semester course. The reader should be familiar with the basic concepts of modern algebra. A course in one complex variable would be helpful, but is not necessary. It is also an excellent text for those working in neighboring fields (algebraic topology, algebra, Lie groups, etc.) who need to know the basics of algebraic geometry.

Dr. Miller emailed me yesterday to confirm that the textbook for his Fall UCLA Extension ‏course Introduction to Algebraic Geometry will be Elementary Algebraic Geometry by Klaus Hulek (AMS, 2003) ISBN: 0-8218-2952-1.

Sadly, I totally blew the prediction of which text he’d use. I was so far off that this book wasn’t even on my list to review! I must be slipping…

🔖 Universal Sign-In Button

Bookmarked Universal Sign-In Button by Malcolm Blaney (unicyclic.com)

The Universal Sign-In Button is a customisable bookmarklet that will auto-fill a sign-in form on the page you are currently visiting and submit it for you. It's a one-click way to tell the current page who you are.

This is simply awesome! I’m such a fan of bookmarklets I actually feel sad I hadn’t thought of doing this before. This simple Universal Sign-in Button tool now greatly reduces the amount of time it takes me to log into IndieWeb and other related sites that offer this functionality.

Signing into websites using my own domain name was an awesome concept, but this greatly speeds up the process and makes it an order of magnitude faster.

Thanks Malcolm!

🔖 Homotopy Type Theory: Univalent Foundations of Mathematics

Bookmarked Homotopy Type Theory: Univalent Foundations of Mathematics

Homotopy type theory is a new branch of mathematics that combines aspects of several different fields in a surprising way. It is based on a recently discovered connection between homotopy theory and type theory. It touches on topics as seemingly distant as the homotopy groups of spheres, the algorithms for type checking, and the definition of weak ∞-groupoids. Homotopy type theory offers a new “univalent” foundation of mathematics, in which a central role is played by Voevodsky’s univalence axiom and higher inductive types. The present book is intended as a first systematic exposition of the basics of univalent foundations, and a collection of examples of this new style of reasoning — but without requiring the reader to know or learn any formal logic, or to use any computer proof assistant. We believe that univalent foundations will eventually become a viable alternative to set theory as the “implicit foundation” for the unformalized mathematics done by most mathematicians.

🔖 Self-Organized Resonance during Search of a Diverse Chemical Space

Bookmarked Self-Organized Resonance during Search of a Diverse Chemical Space (Physical Review Letters)

ABSTRACT Recent studies of active matter have stimulated interest in the driven self-assembly of complex structures. Phenomenological modeling of particular examples has yielded insight, but general thermodynamic principles unifying the rich diversity of behaviors observed have been elusive. Here, we study the stochastic search of a toy chemical space by a collection of reacting Brownian particles subject to periodic forcing. We observe the emergence of an adaptive resonance in the system matched to the drive frequency, and show that the increased work absorption by these resonant structures is key to their stabilization. Our findings are consistent with a recently proposed thermodynamic mechanism for far-from-equilibrium self-organization.

🔖 Spontaneous fine-tuning to environment in many-species chemical reaction networks | PNAS

Bookmarked Spontaneous fine-tuning to environment in many-species chemical reaction networks (Proceedings of the National Academy of Sciences)

Significance A qualitatively more diverse range of possible behaviors emerge in many-particle systems once external drives are allowed to push the system far from equilibrium; nonetheless, general thermodynamic principles governing nonequilibrium pattern formation and self-assembly have remained elusive, despite intense interest from researchers across disciplines. Here, we use the example of a randomly wired driven chemical reaction network to identify a key thermodynamic feature of a complex, driven system that characterizes the “specialness” of its dynamical attractor behavior. We show that the network’s fixed points are biased toward the extremization of external forcing, causing them to become kinetically stabilized in rare corners of chemical space that are either atypically weakly or strongly coupled to external environmental drives. Abstract A chemical mixture that continually absorbs work from its environment may exhibit steady-state chemical concentrations that deviate from their equilibrium values. Such behavior is particularly interesting in a scenario where the environmental work sources are relatively difficult to access, so that only the proper orchestration of many distinct catalytic actors can power the dissipative flux required to maintain a stable, far-from-equilibrium steady state. In this article, we study the dynamics of an in silico chemical network with random connectivity in an environment that makes strong thermodynamic forcing available only to rare combinations of chemical concentrations. We find that the long-time dynamics of such systems are biased toward states that exhibit a fine-tuned extremization of environmental forcing.

An Introduction to the IndieWeb | AltPlatform

Bookmarked An Introduction to the IndieWeb by Chris Aldrich (AltPlatform)

Whether you're starting a blog, building your personal brand, posting a resume, promoting a hobby, writing a personal journal, creating an online commonplace book, sharing photos or content with friends, family, or colleagues, writing reviews, sharing recipes, podcasting, or any one of the thousand other things people do online it all starts with having a presence and an identity online.

I remember some of the difficulties I had in understanding, comprehending, and coming to grasp with the overall concept of the IndieWeb. Then I contended with strategies for navigating my way through the wiki and deciding in what order to do things and finding my way into the rich and diverse community of help and additional resources.

I’ve written an introduction–aimed at beginners (and non-developers)–on AltPlatform.org that I hope might help out others who are thinking about or starting their own journey.

Editor’s Note:
As of December 2017, the AltPlatform.org site which originally published this article has shut down. I’ve smartly kept a private archived copy of the original of this post here on my personal site and manually syndicated a copy of it to AltPlatform for just such a possibility. (Hooray for PASTA (Publish Anywhere, Save to (Private) Archive)!) As a result of the shutdown, I’m making the original public here and you can now read it below.

If you wish, you can also read a copy of the original as it appeared on AltPlatform on the Internet Archive.
