Finding New Shapes in Foam
In the summer of 2018, a group of researchers announced they’d discovered a new geometrical shape, the scutoid. They found the scutoid, a sort of twisted prism, in the shape Keep reading
An Introduction to Turbulence
With some help from Physics Girl and her friends, Grant Sanderson at 3Blue1Brown has a nice video introduction to turbulence, complete with neat homemade laser-sheet illuminations of turbulent flows. Grant Keep reading
Chocolate Fountain
Amidst your holiday celebrations, you may have encountered a chocolate fountain. In a recent paper, applied mathematicians have laid out the physics behind these delicious decorations, and it turns out Keep reading
Reader Question: Fractals and Turbulence
Reader 3d-time asks: Hi, there is a guy, at my college, who is doing a master’s degree thesis in turbulence. He says he uses fractals and computational methods. Can you Keep reading
River Paths
As a follow-up to this recent post about river meander, check out this video from Numberphile about some of the mathematics behind the path of rivers. A river’s course is Keep reading
Solution to a Millennium Prize Problem?
Reports emerged this weekend that Kazakh mathematician Mukhtarbay Otelbaev has published a proposed solution to the Navier-Stokes existence and smoothness problem, one of the seven Millennium Prize problems offered by Keep reading
Fluids Round-up – 16 November 2013
Time for another fluids round-up. Here are your links: PhysicsBuzz takes a look at the use of plasma actuators to control airflow. Over at Deep Sea News, you can learn about parasitic Keep reading
Fluids Round-up – 2 November 2013
Fluids round-up time! Here are your latest links: Over at PhysicsFocus, Colin White discusses the Bernoulli fallacy and other zombie myths of physics. (Via @JenLucPiquant) Aviation Week has an exclusive look at Keep reading
Incense in Transition
A buoyant plume of smoke rises from a stick of incense. At first the plume is smooth and laminar, but even in quiescent air, tiny perturbations can sneak into the Keep reading
