Welcome back. In today’s blog post, we will continue our discussion of hydrodynamic stability by discussing resolvent analysis, which is complementary to classical linear stability analysis. While linear stability analysis looks at the growth of small perturbations to an unforced base flow, resolvent analysis finds maximum gain input-output structures in a flow field that … [Read more...] about Hydrodynamic Stability: Resolvent Analysis

The Impact of Mass Incarceration on the Black Nuclear Family
Mass incarceration has a profoundly destructive impact on the Black nuclear family. The U.S. criminal justice system disproportionately targets Black individuals, particularly men, leading to alarmingly high imprisonment rates in Black communities. This often results in fathers being removed from their households, leaving mothers to raise children alone. The absence of one … [Read more...] about The Impact of Mass Incarceration on the Black Nuclear Family
How Butterfly Wings are inspiring Solar Cell Designs
In the quest for more efficient renewable energy sources, scientists have found inspiration in an unexpected place: butterfly wings. A groundbreaking study, reported by The Verge, reveals how the unique structure of butterfly wings is paving the way for more efficient solar cells. Researchers from the California Institute of Technology (Caltech) and Karlsruhe Institute of … [Read more...] about How Butterfly Wings are inspiring Solar Cell Designs
Small Minds, Smaller Sizes: Brandy Melville and Body Dysmorphia
In an industry where “fitting in” has both literal and metaphorical meanings, fashion brands like Brandy Melville have turned sizing into a struggle for self-worth. With their notorious “one-size-fits-all” business model, Brandy Melville not only sells clothes, but sells the idea that only one type of body is ideal. This approach not only marginalizes many consumers but also … [Read more...] about Small Minds, Smaller Sizes: Brandy Melville and Body Dysmorphia
Hydrodynamic Stability: Non-Normality and Transient Energy Growth
Welcome back. Last week, we derived the Orr-Sommerfeld equation, which governs the evolution of small disturbances in 2D parallel shear flows. This equation was cast as an eigenvalue problem, L𝜑 = c𝜑, that determined stream function amplitudes, 𝜑, and their associated complex wave speeds, c, that characterized the behavior of small perturbations. The governing Orr-Sommerfeld … [Read more...] about Hydrodynamic Stability: Non-Normality and Transient Energy Growth
