    “Kármán Vortex Street”

    Although engineers often consider fluid mechanics through the lens of mathematics, that’s far from the only way to understand fluid physics. Today’s video is an alternative interpretation of a classic flow — the flow around a cylinder — created in a collaboration between dancers and engineers. The result is what they call a “physics-constrained dance improvisation” that shows how the flow changes as its speed increases. I love this concept! It highlights the visual and qualitative differences between flow states and maintains space for artistic creativity. Be sure to watch the full video! (Video and submission credit: J.

    “Starlit”

    In “Starlit” filmmaker Roman De Giuli explores a universe in a fish tank. The planets and asteroids we see are droplets of paint and ink floating in a transparent, gel-like medium. I particularly like the sequences where paint stretches, beads up, and breaks into a string of droplets! (Image and video credit: R. De Giuli)

    Aerial Sheep Flow

    I may never get tired of drone videos of sheep herding. They are mesmerizing to watch and full of so many characteristics of flow. Like a compressible fluid, the herd squeezes together as it passes through a gate, then spreads and decreases density as it reaches the pasture. The sequence of sheep moving down the road reminds me of pipe flow, with a boundary layer of sheep along the edge who choose to graze rather than move with the herd. There are even sheep vortices in this video, folks. Vortices of sheep! How could you resist watching?! (Video credit: L. Patel; via Colossal; submitted by Florian T. and Matevz D.)

    Chasing the Storm

    Towering mountains of convection and ominous colors are staples of Adam Kyle Jackson’s storm photography. His dramatic portraits of supercell thunderstorms highlight the majesty and power of these turbulent phenomena. Make sure to follow him on Instagram for lots more! (Image credit: A.

  • “The Goblet of Fire”

    “The Goblet of Fire”

    Sometimes the mundane events of life hide extraordinary phenomena. This award-winning photograph by Sarang Naik shows yellow-brown spores streaming off a mushroom during monsoon season. The plume is abstract and beautiful; you could easily mistake it for the flames of an Olympic torch. But common as they are, the lowly mushroom hides interesting depths. To get their spores to travel further, mushrooms actually generate their own breezes! (Image credit: S. Naik; via Big Picture Competition)

    With the Olympics kicking off today, FYFD will follow our usual tradition of Olympic-themed posts for the next couple weeks, so be sure to come back each day for the latest featured sport!

    Inside Old-Fashioned Butter

    Today’s video is a little different: it’s an inside look at a butter-making shop in France that uses traditional nineteenth-century methods to process the butter. Watching workers fold and shape 50 kilos of butter is mesmerizing, and it highlights the amorphous, pseudo-fluid nature of the butter. Yes, the butter holds its shape like a solid, but it’s a soft solid at best and certainly shows fluid-like qualities when force is applied. A word of warning: you might not want to watch this on an empty stomach! (Image and video credit: Art Insider; via Colossal)

  • Suspended Sediments in Lake Erie

    Suspended Sediments in Lake Erie

    Lake Erie’s Long Point is outlined in turquoise in this natural-color satellite image. The pale color is likely due to limestone sediments in the shallow waters getting resuspended by a seiche or other disturbance. A seiche is a standing wave that forms in a partially- or fully-bounded body of water; in Lake Erie they are typically wind- and weather-driven. (Image credit: J.

    “Playing With Time”

    The Macro Room team is back with this clever video that messes with our perception of time. I’d hate to give anything away here, so just go check it out! (Image and video credit: Macro Room)

  • “Phoenix Rising”

    “Phoenix Rising”

    This aerial photo of Lake Owens by Paul Hoelen won a 2020 Drone Photo Award in the Abstract category. As Hoelen notes, “The phoenix rising is a symbol of re-emergence from the ashes of fire.” Lake Owens was used for years in mining and other industries, which left the lake desiccated and depleted. But nature is beginning to recover; migratory birds have returned to the lake, and life is beginning anew. (Image credit: P. Hoelen; via Colossal)

    Kinetic Sculptures by Anthony Howe

    These mesmerizing kinetic sculptures built by Anthony Howe are entirely wind-driven. It’s not necessarily apparent in these images, but these sculptures are several meters tall and weigh hundreds of kilograms, but they’re engineered so precisely that the slightest breeze sets them silently spinning. See more of Howe’s art in action on his YouTube channel. (Video and image credits: A. Howe; via Colossal)
