# gst: the way bubbles gallop.

<< ️Bubbles are more than fleeting pockets of air trapped in liquid: they exhibit an ever-expanding repertoire of intriguing behaviors. From da Vinci's sketches of their swirling paths to modern-day studies of their erratic dances under acoustic waves, the rich dynamics of bubbles have long captured the attention of everyday observers, engineers, and scientists alike. When exposed to periodic sound waves, bubbles can shift from regular pulsations to rapid zigzagging, mimicking the randomness of Brownian motion. Under sudden pressure changes, they may collapse violently, producing cavitation—intense shock waves capable of damaging solid surfaces. In extreme cases, the implosion may become so intense that the bubble emits a spark of light. >>

<< ️Bubbles can also challenge common intuition: they may appear to violate Archimedes' principle, sinking against gravity in oscillating fluids, and carbonated drinks. Despite centuries of explorations, new and often surprising bubble phenomena continue to emerge. One such example is the recently discovered “galloping” bubble, introduced in (AA) recent publication. Here, (They) showcase this new mechanism of bubble locomotion, highlighting its rich dynamics and striking visual appeal. >>

# gst: extreme vertical drafts as drivers of Lagrangian dispersion in stably stratified turbulent flows.

<< ️The dispersion of Lagrangian particle pairs is a fundamental process in turbulence, with implications for mixing, transport, and the statistical properties of particles in geophysical and environmental flows. While classical theories describe pair dispersion through scaling laws related to energy cascades, extreme events in turbulent flows can significantly alter these dynamics. This is especially important in stratified flows, where intermittency manifests itself also as strong updrafts and downdrafts. >>

<< ️In this study, (AA) investigate the influence of extreme events on the relative dispersion of particle pairs in stably stratified turbulence. Using numerical simulations (They) analyze the statistical properties of pair separation across different regimes, and quantify deviations from classical Richardson scaling. (Their) results highlight the role of extreme drafts in accelerating dispersion. >>

# gst: active drive towards elastic spinodals

<< Active matter, exemplified by adaptive living materials such as the actomyosin cytoskeleton, can navigate material parameter space, leading to unconventional mechanical responses. In particular, it can self-drive toward elastic spinodal regimes, where inhomogeneous floppy modes induce elastic degeneracy and enable a controlled interplay between rigidity loss and recovery. Proximity to such marginal states leads to stress localization and the formation of force chains that can be actively assembled and disassembled. >> 

Here AA << extend the classical notion of spinodal states to active solids and demonstrate how these extreme mechanical regimes can be actively accessed. Moreover, (They) show that in a nonlinear setting, crossing elastic spinodals generates new energy wells and makes force channeling an intrinsic feature of the emerging microstructure. >>

<< Unexpected and often irreversible shifts in the state or the dynamics of a complex system often accumulate in extreme events with likely disastrous impact on the system and its environment. Detection, understanding, and possible prediction of such critical transitions are thus of paramount importance across a variety of scientific fields. >>

# gst: multiparticle dispersion in rotating-stratified turbulent flows (when stratification increases turbulent fluctuations may not be weaker)

AA << study the relative movement of groups of two (pairs) and four (tetrahedra) Lagrangian particles using direct numerical simulations of the stably stratified Boussinsesq equations, with Brunt-Väisälä frequency 𝑁 and Coriolis parameter 𝑓. >>

<< In all cases considered, (AA) demonstrate that the relative particle motion differs depending on whether dispersion is considered forward or backward in time, although the asymmetry becomes less pronounced when stratification and rotation increase. On the other hand, the strong fluctuations in the dispersion between two particles become more extreme when 𝑁 and 𝑓  increase. (They) also find evidence for the formation of shear layers, which become more pronounced as 𝑁 and 𝑓  become larger. Finally, (They) show that the irreversibility on the dispersion of a set of particles initially forming a regular tetrahedron becomes weaker when the influence of stratification and rotation increases, a property that (They) relate to that of the perceived rate-of-strain tensor. >>️

<< Unexpectedly, (AA) observe that the higher moments of particle separation, in particular the normalized fourth-order central moment of the separation (the kurtosis Kr) is an increasing function of stratification and rotation. This is surprising, as when stratification increases the turbulent fluctuations are expected to be weaker, (..) >>️

# gst: black swan ... or black rabbit?

<<

In his book The Black Swan: The Impact of the Highly Improbable, Nassim Nicholas Taleb explores the profound and unpredictable events that shape our world, which he calls “Black Swans.” These events are characterized by three main features: they are rare and unpredictable, they have an extreme impact, and in hindsight, they often seem explainable or inevitable. Taleb argues that our world is increasingly shaped by these Black Swans, from financial crises to technological breakthroughs, and yet humans are inherently ill equipped to anticipate them due to cognitive biases and reliance on standard predictive models. By analogy with this term, (AA) have named Black Rabbits events that exhibit all the external characteristics of a Black Swan but are entirely determined by the state of the system itself. These phenomena are not artificial examples or mere curiosities; they exist wherever hyperbolic meadows are found. When we witness a social catastrophe or a financial crisis, could it be not a stray Black Swan but a local Black Rabbit? How can one determine in advance that a system is pregnant with a crisis? What indicators can be used? Is it possible to control the system to prevent it from becoming unstable? These are intriguing questions, perhaps too complex, especially when dealing not with simple mathematical models but with real-world systems. Yet, we must still strive to find answers to them.

# gst: intermittency of bubble deformation in turbulence.

<< The deformation of finite-sized bubbles in intense turbulence exhibits complex geometries beyond simple spheroids as the bubbles exchange energy with the surrounding eddies across a wide range of scales. (AA)  study investigates deformation via the velocity of the most stretched tip of the deformed bubble in three dimensions, as the tip extension results from the compression of the rest of the interface by surrounding eddies. >>

<< The results show that the power spectrum based on the tip velocity exhibits a scaling akin to that of the Lagrangian statistics of fluid elements, but decays with a distinct timescale and magnitude modulated by the Weber number based on the bubble size. This indicates that the interfacial energy is primarily siphoned from eddies of similar sizes as the bubble. >>

<< Moreover, the tip velocity appears much more intermittent than the velocity increment, and its distribution near the extreme tails can be explained by the proposed model that accounts for the fact that small eddies with sufficient energy can contribute to extreme deformation. >>

<< These findings provide a framework for understanding the energy transfer between deformable objects and multiscale eddies in intense turbulence. >>

# life: landing on a swinging perch: peach-faced lovebirds (Agapornis roseicollis) prefer extremes.

<< Birds frequently must land safely and accurately on moving branches or power lines, and seemingly accomplish such maneuvers with acrobatic precision. To examine how birds target and land successfully on moving supports, (AA) investigated how peach-faced lovebirds (Agapornis roseicollis) approach and land on a swinging perch.  >>️

<< In support of (AA) hypothesis for stable landings, lovebirds timed their landings in a majority of trials (51.3%), when the perch was approaching either extreme of its motion with its velocity nearing zero (27.5% in the same direction as the bird’s approach – SDs, and 23.8% in the opposite direction to the bird’s approach – ODs). As a result, lovebirds exhibited a robust bimodal strategy for timing their landing to the phase of the swinging perch. Less commonly, lovebirds landed when the perch was moving at high velocity either toward the bird’s approach (12.3%) or in the same direction as the bird’s approach (11.5%); with the remainder (21.9%) of trials distributed over a broad range of swing phases. >>️

# jazz: Eastside Romp. Jeff Parker (gui), Eric Revis (b), Nasheet Waits (d).

<< In May 2016, guitarist Jeff Parker, double bassist Eric Revis, and drummer Nasheet Waits spent a single day recording in a Pasadena studio. The seven tunes they cut appear on Eastside Romp. Mixed in 2018, it sat on a shelf for four more years. (..) No one except the creators know why it took six long years for this relaxed yet canny set to arrive, but its appearance adds immeasurably to the mystique and inventive creativity of these three musicians. >> Thom Jurek (T.J.)

- Drunkard's Lullaby

️<< "Drunkard's Lullaby" is a group improvisation, laden with guitar effects, knotty bass vamps, and dialogic conversation between snare, hi-hat, and kick drum. Parker's abstracted soloing is saturated in distortion, and it short-circuits, staggering his already jagged lines, creating a barely restrained sense of power. The rhythm section intersects and interlocks in detailed, propulsive conversation as the guitar travels afield, adding more frenetic yet glitchy notes and layers of feedback. >> (T.J.)

- Wait

<< "Wait," the album's longest cut, was composed by the guitarist. It commences as a dirge led by Revis playing vamped chords. He establishes a circular vamp as Parker points at his changes and Waits dances limpidly on his tom-toms in 4/4. The languid lyric line crisscrosses post-bop, Spanish-tinged modalism, and blues. Parker moves between melody and angular improv as his bandmates respond with empathy, highlighting and expanding the reach of his labyrinthine harmonic lines. As a perfect complement, Waits offers a studio version of his oft-performed nugget "Between Nothingness and Infinity." Paraphrasing the title of 1973's live Mahavishnu Orchestra album Between Nothingness & Eternity, he frames a musical narrative that emerges directly out of Parker's deeply moving ballad-esque playing, adding textural airiness, rhythmic spaciousness, and harmonic depth to its melody. >> (T.J.)

- Similar Limits 

<< Opener "Similar Limits" is the set's only cover. Composed by the late alto saxophonist Marion Brown, it originally appeared on 1967's Porto Novo. The trio keep the iconic, Monk-esque intro after a brief roll from Waits. Parker and Revis play the staggered melodic intro as Waits rolls, fills, and accents all over the kit. As the bassist expands the tune's harmonic reach, Parker explores the underside with great sensitivity and swing. >> (T.J.)️
