#Deep web iceberg explained software

You may have heard some disturbing stories about the deep web such as illegal drug trading, child pornography, hitman associations and some other criminal activities. This is the part of the iceberg that’s invisible to surface observers. The deep web, on the other hand, is substantially bigger than the clearnet – about 500 times in content volume. The surface net, or the visible tip, is just a small part of the iceberg. The best way to describe the visibility of the internet is to use the iceberg analogy. The truth is, the clearnet is said to be only 4% of the entire web. If the clearnet covers every site that everyone can access every day, then it must be huge, right? Not really. “I’ve suggested to people that in addition to the Iceberger website they can also take an ice cube or a cork from a wine bottle and put them in water and see that they’ll float on their side,” Thompson-Munson told GlacierHub.This means YouTube, Facebook, The New York Times – all websites that can be casually accessed with a typical browser are part of the clearnet. While most people don’t have the opportunity to witness huge icebergs floating in the Earth’s polar regions, there are a few other ways people can visualize them at home. “If the iceberg isn’t symmetrical, meaning the center point of the iceberg is a little off to the left or right, then the iceberg will rotate until equilibrium between the center of the iceberg’s gravity and the buoyancy force is established.” “The key thing to understand is the alignment between the force of gravity that pulls the iceberg down at its center of gravity and the buoyancy of the water that pushes up on the iceberg,” explained Tauberer. In Thompson-Munson’s Twitter thread, she included a popular article by Henry Pollack, an emeritus professor of geophysics at the University of Michigan, explaining why icebergs float on their side instead of vertically. The scientific explanation for why an iceberg will float on its side comes from a simple interaction between two forces, gravity and the water’s buoyancy. “I combined this with my knowledge of scientific computing and made a web app, Iceberger.” Another online simulator, Iceberger Remixed, was created soon after where users can choose preset shapes and see how melting will affect the icebergs. “After reading the thread on the tweet, I saw that there is a really simple mathematical explanation for the underlying principle of how an iceberg floats,” he said.

Megan Thompson-Munson February 19, 2021Ī day later, Josh Tauberer, a software developer and civic technologist, created an interactive website where people can draw their own theoretical iceberg and see how it would float in the ocean. I went to the trouble of painting a stable iceberg with my watercolors, so plz hear me out. Today I channeled my energy into this very unofficial but passionate petition for scientists to start drawing icebergs in their stable orientations. This tweet soon went viral, with many glaciologists praising her for finally setting the record straight on how an iceberg actually floats. “So when I set out to draw my own iceberg, I realized that all of these were wrong and I had to draw it differently.”Īfter finishing her watercolor, she tweeted it out in late February with a thread of scientific background. “I found myself looking at a screen of drawings and paintings of icebergs in unstable positions,” she told GlacierHub.

When Thompson-Munson searched online for images of icebergs to inspire her watercolor paintings, they didn’t resemble the icebergs she had seen in her own research. When coastal glaciers flow, masses of ice calve off into the ocean. Her research made her well aware that as the climate changes, the melting of glaciers and ice sheets is accelerating and there is an increase in icebergs calving, or breaking off of, ice sheets or glaciers.

Megan Thompson-Munson, a PhD student at the University of Colorado Boulder studying the interactions between ice sheets and a changing climate, was looking for a way to bridge her newfound pandemic hobby, watercolor painting, and her research.
