What is the turbulence problem, and when can we say it’s solved?
This deep dive by Sreenivasan & Schumacher explores the math, physics, and engineering challenges of turbulence—from Navier-Stokes equations to intermittency and beyond. A must-read for anyone fascinated by chaos, complexity, and the unsolved mysteries of fluid dynamics! 🌪️🌀 #Turbulence

Baseball's Mysterious Rubbing Mud - FYFD
Since 1938, every ball in Major League Baseball has been covered in a special "rubbing mud" harvested from a secret location in New Jersey. Although the league has tried in the past to replace the mud...
Rheology of rubbing mud reveals that it is "shear thinning". It rubs like lotion and fills in the holes.

How AI models are transforming weather forecasting: a showcase of data-driven systems | ECMWF
Developments in machine learning are continuing at breathtaking pace, both inside and outside of weather forecasting. To help assess machine learning weather forecasts from different sources, we now show a range of them in ECMWF’s charts catalogue.
Swimming often results in water getting stuck in our ear canals. The narrow space, combined with the waxy surface, is excellent at trapping small amounts of water. If left in place, that excess flu…
TLDR: To remove by shaking one would need accelerations high as 24g, which can damage the ear. A couple drops of vinegar or alcohol in the ear will lower the surface tension and make the fluid easier to remove
AMA! Ph.D. in geophysical fluid mechanics and stratified flows
Hi all! I defended my Ph.D. thesis back in 2019 and I also served as the creator and moderator for the subreddit r/FluidMechanics for a long time. I think with that I have gathered enough experience and courage to answer some of your queries. Some broad topics that I can answer questions on are:
Ask away!
The Feynman Lectures on Physics
The classic transcripts of Feynmans Lectures are now open and free! Some chapters are great to get a different perspective on theoretical fluid mechanics.
JFM webinar series
Seamlessly organise, run and publish academic research seminars. Get started in minutes.
The JFM webinar series which was a great source of high quality research-based open seminars during the pandemic continues to thrive. It is now hosted in a different platform. It runs every first Friday of the month at 4pm.
