# Mathpix will solve handwritten math equations for you

Today is the first time in a decade that I actually wished I was back in school. Mathpix is an iOS app that can recognize and answer handwritten math equations in seconds. Open the app, point the camera toward your math problem (you’ll need legible handwriting, or it won’t work properly), and it’ll give you the correct answer along with step-by-step directions to reach the solution. Mathpix even works with more complex equations that require graphs or charts.

The app works by sending the equation to a server, so you’ll need a connection to use it. Usually a math app that can solve problems wouldn’t be allowed in schools, but Mathpix is essentially a far better version of the now very old TI-84 graphing calculator, and a lot cheaper (it’s free). You can download Mathpix on iOS today.

## Scientists Discover That James Joyce’s Finnegans Wake Has an Amazingly Mathematical “Multifractal” Structure

Art, Literature, Math| March 16th, 2016 1 CommentIt has long been thought that the so-called “Golden Ratio” described in Euclid’s

Elementshas “implications for numerous natural phenomena… from the leaf and seed arrangements of plants” and “from the arts to the stock market.” So writes astrophysicist Mario Livio, head of the science division for the institute that oversees the Hubble Telescope. And yet, though this mathematical proportion has been found in paintings by Leonardo da Vinci to Salvador Dali—two examples that are only “the tip of the iceberg in terms of the appearances of the Golden Ratio in the arts”—Livio concludes that it does not describe “some sort of universal standard for ‘beauty.’” Most art of “lasting value,” he argues, departs “from any formal canon for aesthetics.” We can consider Livio a Golden Ratio skeptic.Far on the other end of a spectrum of belief in mathematical art lies Le Corbusier, Swiss architect and painter in whose modernist design some see an almost totalitarian mania for order. Using the Golden Ratio, Corbusier designed a system of aesthetic proportions called Modulor, its ambition, writes William Wiles at Icon, “to reconcile maths, the human form, architecture and beauty into a single system.” Praised by Einstein and adopted by a few of Corbusier’s contemporaries, Modulor failed to catch on in part because “Corbusier wanted to patent the system and earn royalties from buildings using it.” In place of Leonardo’s

Vitruvian Man, Corbusier proposed “Modulor Man” (below) the “mascot of [his] system for reordering the universe.”Perhaps now, we need an artist to render a “Fractal Man”—or Fractal Gender Non-Specific Person—to represent the latest enthusiastic findings of math in the arts. This time, scientists have quantified beauty in language, a medium sometimes characterized as so imprecise, opaque, and unscientific that the Royal Society was founded with the motto “take no one’s word for it” and Ludwig Wittgenstein deflated philosophy with his conclusion in the

Tractatus, “Whereof one cannot speak, thereof one must be silent.” (Speaking, in this sense, meant using language in a highly mathematical way.) Words—many scientists and philosophers have long believed—lie, and lead us away from the cold, hard truths of pure mathematics.And yet, reports

The Guardian, scientists at the Institute of Nuclear Physics in Poland have found that James Joyce’sFinnegans Wake—a novel we might think of as perhaps the most self-consciously referential examination of language written in any tongue—is “almost indistinguishable in its structure from a purely mathematical multifractal.” Trying to explain this finding in as plain English as possible, Julia Johanne Tolo atElectric Literaturewrites:To determine whether the books had fractal structures, the academics looked at the variation of sentence lengths, finding that each sentence, or fragment, had a structure that resembled the whole of the book.

And it isn’t only Joyce. Through a statistical analysis of 113 works of literature, the researchers found that many texts written by the likes of Dickens, Shakespeare, Thomas Mann, Umberto Eco, and Samuel Beckett had multifractal structures. The most mathematically complex works were stream-of-consciousness narratives, hence the ultimate complexity of

Finnegans Wake, which Professor Stanisław Drożdż, co-author of the paper published atInformation Sciences, describes as “the absolute record in terms of multifractality.” (The graph at the top shows the results of the novel’s analysis, which produced a shape identical to pure mathematical multifractals.)This study produced some inconsistencies, however. In the graph above, you can see how many of the titles surveyed ranked in terms of their “multifractality.” A close second to Joyce’s classic work, surprisingly, is Dave Egger’s post-modern memoir

A Heartbreaking Work of Staggering Genius, and much, much further down the scale, Marcel Proust’sRemembrance of Things Past.Proust’s masterwork, writes Phys.org, shows “little correlation to multifractality” as do certain other books like Ayn Rand’sAtlas Shrugged. The measure may tell us little about literary quality, though Professor Drożdż suggests that “it may someday help in a more objective assignment of books to one genre or another.” Irish novelist Eimear McBride finds this “upshot” disappointing. “Surely there are more interesting questions about the how and why of writers’ brains arriving at these complex, but seemingly instinctive, fractals?” she toldThe Guardian.Of the finding that stream-of-consciousness works seem to be the most fractal, McBride says, “By its nature, such writing is concerned not only with the usual load-bearing aspects of language—content, meaning, aesthetics, etc—but engages with language as the object in itself, using the re-forming of its rules to give the reader a more prismatic understanding…. Given the long-established connection between beauty and symmetry, finding works of literature fractally quantifiable seems perfectly reasonable.” Maybe so, or perhaps the Polish scientists have fallen victim to a more sophisticated variety of the psychological sharpshooter’s fallacy that affects “Bible Code” enthusiasts? I imagine we’ll see some fractal skeptics emerge soon enough. But the idea that the worlds-within-worlds feeling one gets when reading certain books—the sense that they contain universes in miniature—may be mathematically verifiable sends a little chill up my spine.

# Some Educators Question If Advanced Math Should Be Required : NPR

Algebra is the one course that prevents the most people from graduating high school, and it’s the single most failed course in community colleges. Now some educators are questioning whether people really need these skills as adults, and whether it’s time for a new approach to teaching math.
