Sonic Black Holes: Creating Universe Analogues in the Laboratory

November 16, 2024

A captivating illustration depicting the creation of a sonic black hole in a laboratory setting. The central focus is a swirling vortex of Bose-Einstein condensate, illuminated by a vibrant spectrum of colors, representing the trapped sound waves. In the background, scientists meticulously monitor the experiment, their faces illuminated by the soft glow of computer screens. The overall mood should be one of awe and wonder, emphasizing the elegance and precision of scientific exploration. The scene should be rendered in a stylized, almost futuristic aesthetic, showcasing the beauty and complexity of scientific discovery.

One of the most clever methods scientists are investigating cosmic events without leaving Earth is through sonic black holes, sometimes known as acoustic black holes. Having worked on experiments producing sonic black holes with Bose-Einstein condensates, I have seen how exactly these systems replicate their cosmic counterparts. These lab models replicate the behavior of light ...

The Weird World of Non-Newtonian Fluids

November 8, 2024

A surreal and colorful illustration depicting the bizarre nature of non-Newtonian fluids. Imagine a vibrant, almost abstract scene where a hand plunges into a pool of shimmering, blue "oobleck," causing it to solidify into a solid-like form. The background could feature a blend of swirling, dynamic shapes and patterns representing the unpredictable flow of these fluids. The scene should evoke a sense of both wonder and scientific curiosity, capturing the interplay between science and art. Incorporate elements of abstract expressionism, highlighting the fluid and dynamic nature of the subject.

Non-Newtonian fluids defy the traditional rules of viscosity, changing their flow behavior under stress. From the fun of running across a pool filled with cornstarch and water to the science behind how these fluids can become solid under impact, this article dives into their quirky properties. A hands-on experiment at a science fair where I ...
