A “real-time” animation of the seismic (vertical) velocity of Italy’s 5.5 Mw earthquake that hit between the Aquila and Rieti provinces. The second half of the animation shows the whole country and surrounding area.
Real-time indicates that the video reflects how the waves propagated in real-time. It’s neither slowed down not sped up.
Red color indicates relatively higher vertical velocities indicating the ground is moving upwards while the blue color indicates the lower (negative) velocities indicated a downward movement of the ground. Color intensity refers to the magnitude.
In a previous post you read about Jacqueline du Pré‘s loss of ability to play. In this post I share with you a previously unpublished interview with her from 1980. Following that is a re-edited version of a film made in 1967. She was in love with Elgar’s concerto (see previous post for her performance)
In a previous post we selected some resources on fluid dynamics. In that post we suggested the videos from the National Committe for Fluid Mechanics (notes on the website) that date to the 1960’s and is an excellent exposition to fluid mechanics. We share them below following a very clear demonstration of Euler’s equation and Bernoulli’s integral:
On December 15, 2016 NASA successfully launched 8 small satellites by releasing a rocket from an airplane. The 8 satellites form the Cyclone Global Navigation Satellite System (CYGNSS) for tracking and studying the inside of tropical storms and hurricanes.
This step of releasing a rocket from an airplane is part of cutting costs.
Fluid dynamics keep astonishing scientists. Every video or animation of a fluid dynamics experiment brings new information and provides stunning displays.
Here are a few video from the APS Fluid Motion gallery.
Starfish larvae generate vortices when swimming which it utilizes to capture and eat algae.
