Rayleigh-Benard Convection (two-dimensional and very turbulent) - YouTube
Numerical simulation of highly turbulent two-dimensional Rayleigh-Benard convection. Be sure to watch this in HD!
Hot (red) fluid rises from the hot bottom plate while cold (blue) fluid falls down from the cold top plate. The mean temperature corresponds to white.
The Rayleigh number is 10^13 and the Prandtl number is 1; the aspect ratio of the simulation is 16:9.
Two seconds of the video correspond to one so-called free-fall time unit, i.e. the travel-time from plate to plate of a parcel of hot fluid that is accelerated by gravity and not slowed down by surrounding fluid.
The numerical resolution is 7680x4320 gridpoints, i.e. one pixel of the 1080p-Video corresponds to 4x4 gridpoints.

aschn/gnuplot-colorbrewer: ColorBrewer color schemes for gnuplot
An easy way to use the beautiful color schemes at ColorBrewer in the handy command-line plotting program gnuplot.

All ColorBrewer color schemes that include at least 8 colors are included. Each color scheme provides 8 discrete colors and a continuous color palette. See the examples directory for sample code and output.

There’s a big problem with AI: even its creators can’t explain how it works

In 2015, researchers at Google modified a deep-learning-based image recognition algorithm so that instead of spotting objects in photos, it would generate or modify them. By effectively running the algorithm in reverse, they could discover the features the program uses to recognize, say, a bird or building. The resulting images, produced by a project known as Deep Dream, showed grotesque, alien-like animals emerging from clouds and plants, and hallucinatory pagodas blooming across forests and mountain ranges.

What can Ansel Adams’s enduring photography teach us in the age of Instagram? | Aeon Videos
With an oeuvre that’s both innovative and enduring, the US photographer Ansel Adams is almost universally regarded as a master of his craft and a pioneer in photographic art. Because his black-and-white landscapes have become so ubiquitous – commonly found on postcards, computer backgrounds and doctor’s office walls – it’s easy to take the beauty of his images for granted. But as Evan Puschak (also known as The Nerdwriter) shows in this video essay, there’s perhaps never been a better time to re-examine the careful, deliberate approach Adams took to his work.

V0088: Turning on a Dime – Asymmetric Vortex Formation in Hummingbird Maneuvering
Hummingbirds are versatile natural flyers that can perform locomotion as insects, such as hovering, forward/backward flight, turning maneuver and more. The unsteady vortex dynamics is key to understand aerodynamic features of these motions. Here we present an integrated approach combining high-speed photogrammetry, wing/body surface tracking, and immersed boundary method based flow simulations to study the three-dimensional vortex dynamics of a freely maneuvering hummingbird. The simulation results of the hummingbird performing pure yaw turn show asymmetric wake structures between the inner and outer wings. Dual-loop vortex structures have been observed in the near wake of the outer wing during downstroke, and of the inner wing during upstroke. The interactions between the wings and these complex vortex structures have implied both aerodynamic and dynamic benefits of the flapping wings in hummingbird’s maneuvering flight. (This work is supported by NSF CBET-1313217 and AFOSR FA9550-12-1-0071)

Twitter Hive Plots
I spend a good deal of time creating and interpreting graph drawings. Visualizing these network representations can be helpful in generating testable hypotheses or as a starting point towards understanding latent features in a data set. The most ubiquitous network representation is probably the force-directed layout. The idea of the algorithm is to use attractive forces of adjacent edges and repulsive forces of other nodes to construct an optimized graph visualization. Below is an example I constructed using my Twitter followers. Nodes represent my followers and edges represent instances where one of my followers follows another one of my followers—mousing over nodes will reveal Twitter usernames:
