New research on the fluid dynamics of the Boston Molasses Flood

A new scientific analysis aims to understand the fluid dynamics of the Boston Molasses Flood. The bursting of an enormous (about 2 million gallons) tank of molasses created one of the biggest disasters ever to hit that city. Although it happened almost a century ago — on January 15, 1919 — there’s been only a vague scientific understanding of […]

Fluid Dynamics and the Potential Cost of Long Genitalia in Male Guppies

Male guppies with long genitals may swagger, physically in a current, and metaphorically in the grand scheme of reproduction. Or not. This newly published study explores these questions: “A Potential Cost of Long Genitalia in Male Guppies: the Effects of Current Speed on Reproductive Behaviour,” Lucia Kwan, Adam N. Dobkin, F. Helen Rodd, and Locke […]

Coming attraction: Disgust: The Fluid Dynamics of the Gross

Fluid dynamics will swirl, both socially and scientifically, in Portland, Oregon, in November. The annual meeting of the American Physical Society (APS) Division of Fluid Dynamics will feature a disgust-packed, juicy special session: Session L1: Focus Session – Disgust: The Fluid Dynamics of the Gross Monday, November 21, 2016, 4:30PM L1.00001: A numerical investigation of a simplified human birth […]

The Physics of Water-skipping Stones

In stone skipping, one tosses a stone with a flattened surface across water (or other fluid) to try to get it to bounce as many times as possible. (There are also military applications, but let’s stick to the fun stuff.) A few months ago, mechanical engineer Tadd Truscott and collagues wrote a quick study on […]

A poetical, time-centric film about fluid dynamics

Flora Lichtman produced another poetical video for Science Friday, this one about the mammal micturation duration research study that is garnering so much attention, and that will be discussed as part of a landmark session at the APS Division of Fluid Dynamics, in Pittsburgh, Pennsylvania, on Sunday, November 24, 2013: BONUS: Listen to Science Friday‘s radio […]

Birth-Fluid Dynamics, and the Splashy Hydrodynamics of Urination

Aatish Bhatia (of  Empirical Zeal) alerts us to an outpouring of soon-to-be-announced birth-centric and micturation-modulation fluid dynamics insights. Anne Staples [pictured here], of Virginia Polytechnic Institute and State University, will chair a session on “Pumping Phenomenon“, at the American Physical Society’s 66th Annual Meeting of the APS Division of Fluid Dynamics,in Pittsburgh, Pennsylvania, on Sunday, […]
