Did soap bubbles ever look so beautiful?

Here is a photograph that has been circulating the science news in the last couple of days, simply because it is so unusual, so intriguing, and so beautiful.

It is a photo from a research paper titled Visualization of flow patterns past various objects in two-dimensional flow using soap film. The researchers point out that a simple soap bubble is possibly the most powerful and effective medium when it comes to researching fluid dynamics.

The authors explain: “Although many advanced experimental flow visualizations, such as particle image velocimetry or laser Doppler velocimetry, have been developed and used in fluid dynamics research, the use of flowing soap films has remained as an educational tool and economical visualization technique to study fluid-structure interaction and hydrodynamic instability in two-dimensional fluid flows. Making use of the optical properties of the soap film and high-speed photography, the wake evolution and vortex patterns behind different bodies can be tracked and captured.”

This photograph is – as many writers and bloggers have noted – “a beautiful reminder that Physics is everywhere, even in soap”.
