Watch Venice’s New $7 Billion Flood Defense System in Action

There are capitals unlikely to be much afflicted by rising sea levels — Indianapolis, say, or La Paz — but Venice looks set for a much more dire fate. Still, there is hope for the Floating City, a hope held out by large-scale engineering projects like the one profiled in the Tomorrow’s Build video above. Called MOSE (an acronym standing for MOdulo Sperimentale Elettromeccanico), the system consists of “78 gates, each 20 meters wide, that rise up out of the water when flooding is imminent.” This sounds like just the ticket for a city that, “built in the middle of a lagoon,” has “been susceptible to a natural phenomenon known as acqua alta, or ‘high water,’ since its founding in the fifth century.”

MOSE is now “finally up and running, eighteen years after construction began” — and a decade after its original completion deadline. This was too late, unfortunately, to spare Venice from the 2019 flood that ranked as its worst in 50 years, leaving 80 percent of the city underwater.

“The good news is, it passed the first major test,” successfully protecting the city in October of last year “from a 1.3-meter high tide, and it’s performed multiple times since. But this doesn’t mean that flooding’s been stopped entirely. In December, it was unable to prevent an unexpectedly high tide from sweeping in and drenching the city once again.” Technically, that incident wasn’t MOSE’s fault: “Weather forecasters underestimated how high the water would get, so authorities kind of didn’t think to switch it on.”

This speaks to the difficulty of not just designing and installing a complex mechanical defense mechanism, but also of getting it to work in concert with the other systems already performing functions of their own (and at various levels of reliability). At a cost of over €6 billion (or $7 billion), MOSE has become “far more expensive than first predicted,” and thus faces that much higher a burden of self-justification, especially given the cloud of “corruption, environmental opposition, and questions about its long-term effectiveness” hanging over it. Seen in action, MOSE remains an unquestionably impressive work of engineering, but its associated headaches have surely converted some to the position on Venice once advanced by no less a scholar and lover of that storied city than Jan Morris: “Let her sink.”

Ishkur’s Guide to Electronic Music: An Interactive, Encyclopedic Data Visualization of 120 Years of Electronic Music

In a very short span of time, the descriptor “electronic music” has come to sound as overly broad as “classical.” But where what we (often incorrectly) call classical developed over hundreds of years, electronic music proliferated into hundreds of fractal forms in only decades. A far steeper quality curve may have to do with the ease of its creation, but it’s also a factor of this accelerated evolution. Music made by machines has transformed since its early 20th-century beginnings from obscure avant-garde experiments to massively popular genres of global dance and pop. This proliferation, notes Ishkur—designer of Ishkur’s Guide to Electronic Music —hasn't always been to the good. Take what he calls “trendwhoring,” a phenomenon that spawns dozens of new works and subgenera in short order, though it’s arguable whether many of them should exist. Ishkur, describes this process below in an excerpt from his erudite, sardonic “Frequently Unasked Questions”: If fart noises were sudde...

A 10 Billion Pixel Scan of Vermeer’s Masterpiece Girl with a Pearl Earring: Explore It Online

We admire Johannes Vermeer’s  Girl with a Pearl Earring   for many reasons , not least that it looks exactly like a girl with a pearl earring. Or at least it does from a distance, as the master of light himself no doubt stepped back to confirm countless times during the painting process, at any moment of which he would have been more concerned with the brushstrokes constituting only a small part of the image. But even Vermeer himself could have perceived only so much detail of the painting that would become his masterpiece. https://www.youtube.com/watch?v=cKaZYTwmjwU Now, more than 350 years after its completion, we can get a closer view of Girl with a Pearl Earring  than anyone has before through a newly released  10 billion-pixel panorama . At this resolution, writes Petapixel’s Jason Schneider , we can “see the painting down to the level of 4.4-microns per pixel.” Undertaken by Emilien Leonhardt and Vincent Sabatier of 3D microscope maker Hirox Europe ...

Drunk History Takes on the Father of Prohibition: The Ban on Alcohol in the U.S. Started 100 Years Ago This Month

There may be plenty of good reasons to restrict sales and limit promotion of alcohol. You can search the stats on traffic fatalities, liver disease, alcohol-related violence, etc. and you’ll find the term “epidemic” come up more than once. Yet even with all the dangers alcohol poses to public health and safety, its total prohibition has seemed “so hostile to Americans’ contemporary sensibilities of personal freedom,” writes Mark Lawrence Schrad at The New York Times , “that we struggle to comprehend how our ancestors could have possibly supported it.” Prohibition in the United States began 1oo years ago-- on January 17, 1920--and lasted through 1933. How did this happen? Demand, of course, persisted, but public support seemed widespread. Despite stories of thousands rushing bars and liquor stores on the evening of January 16, 1920 before the 18th Amendment banning alcohol nationwide went into effect, “the final triumph of prohibition was met with shrugs…. The United States had...
