![]() This single-mind perspective recognizes that thinking can be fast or slow but focuses on differences in operating conditions (variations in the constraints placed upon a single system) rather than differences in operating principles (distinctions between multiple systems). Rather than suggesting the existence of two separate minds, the available evidence supports the idea of a single mind that shifts between a careful, deliberate mode of operation and a quick-and-dirty mode of operation. For instance, processes that are often regarded as being at the core of the unconscious mind (e.g., implicit bias, conditioning, habits) have been shown to be consciously accessible or to depend heavily on conscious thought ( see De Houwer et al., 2019, for an open access review). ![]() ![]() Moreover, modern empirical research on unconscious thinking reveals various layers of complexity.

Origins: The explanation reproduced above about a diver in St. This simplification glosses over the important point that conscious thinking probably controls many aspects of our unconscious thinking. They estimated the weight at 300,000,000 tons.

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.
