Wired Magazine has posted a great gallery of 10 amazing Scientific Visualizations. Covering astronomy, genetics, biology, and physics, it’s a great view at some fantastic work. The image above is the Mototic Spindle of Yeast.
By spending two years with scientists from an array of fields — including physicists, biologists and computer scientists — artists were able to piece together this proposed model of a mitotic spindle in yeast.
The green represents rod-like microtubles, yellow represents DNA, and proteins are shown in red and purple.
Next month’s SuperComputing 2011 event in Seattle, WA will feature some of the biggest names in high performance computing, and where the computers go so do the data analysis and visualization people. One name at the event, Kelly Gaither, is responsible for this year’s “Scientific Visualization Showcase”.
What is most enticing about this year’s “SciVis” vignette is the concerted effort in abstracting the science and technique from its analytical interpretation. Kelly makes data vivid …tangible and textured…visual…stimulating…enticing…visceral…art. And, while “SciVis” is a common practice, from remote visualization to large projection and cave displays to observe “data” in depth and motion, Kelly’s innovative endeavors promise to reach far beyond the scientific realm and spur imagination.
Kelly Gaither & TACC are big proponents of massive tiled displays so I’m sure there will be several to see. In addition, they do some interesting work in web-enabled remote visualization via their tools EnVision & Longhorn. Hopefully they’ll have some other neat stuff to show off this year as well.
The International Science & Engineering Visualization Challenge is coming up, and to open the submission process they’ve released a great video highlighting the winners since 2006.
Creating visualizations of scientific data is a particularly challenging task. It requires artistry, advanced computing skills, the ability to grasp the scientific concepts, and the creativity to conceive of new ways to display data. The successful visualization must be pleasing to both the eye and intellect, providing researchers with practical, even insightful perspective on their data.
The latest issue of Scientific Computing has a great article from some NASA researchers on analyzing and visualizing airflow around landing gear, in hopes of redesigning them to reduce vibration and “aeroacoustic” effects (eg, Loud rumbling). If you see their “Digital magazine” Version you can see some movies of their visualizations.
To generate the flow animations presented here required saving a small portion (12,000 snapshots or time steps) of the flow simulation record. With each snapshot resulting in a file size on the order of 4 to 5 gigabytes, the total time record saved is in excess of 50 to 70 terabytes of data. Although such an aggregated file size is not excessively large by today’s standards, it is still too large for routine visualization of the results. The push toward much larger simulations (a nose gear computation on a grid twice as large as the current grid is ongoing) precludes relying on traditional methods for post-processing of CFD data; that is, saving the volumetric information at each time step for analysis at a later time, as these are highly inefficient and no longer practical. Such large datasets demand concurrent real-time simulation, analysis and visualization of the flow field without the need to save countless terabytes of information that would soon tax the storage capacity of even the largest supercomputers.
Scientific visualization of high-fidelity, large-scale flow simulations such as these has become an indispensable tool for providing global insights and knowledge that enable the development of viable engineering solutions to pressing environmental issues affecting the public good. The landing gear simulations, for example, together with those from other disciplines relevant to aircraft design, will soon be used to help develop a new breed of subsonic aircraft that will not only reduce noise pollution, but will burn less fuel and produce fewer harmful emissions — all to improve life on our planet.
InformationAesthetics brings us an interesting new paper from PhD student Niels Willems that combines multiple visualization techniques to visualize various shipping routes.
The combination of two fields (i.e. a large and small kernel), provides overview and detail: a large kernel provides an overview of area usage revealing vessel highways. Details of speed variations of individual vessels are shown with a small kernel, highlighting anchoring zones where multiple vessels stop.
I just found the YouTube page for “WaveAnimations”, a user that is developing new flow simulations for ship hulls, who has several beautiful videos of simulation results. Covering transom waves, plunging and breaking waves, asymmetrical waves, and several others, they are just beautiful and hypnotic to watch.
Disclaimer: I work for the lab that created the videos & visualizations, but not the Simulation.
As a followup to PhysOrg’s Argonne announcement of the massively parallel simulation and visualization of the supernova explosion, New Scientist has gathered some of the images for a fantastic look at how the data really look.
The recent government DDoS, suspected of originating from Korea, has been hot news lately but the vague sensationalist comments appearing the media make it difficult to know the actual scale of the problem. ShadowServer aims to correct this by providing up-to-date visualizations of botnets and DDoS attacks through simple graphs that track historical activity over daily, monthly, and annual graphs. Shown above is the most recent chart of the weekly DDOS activity, with the huge spike on Thursday. Many more charts are available on their site.
I just found an account on YouTube named udiprob that has several animations of physics and computer algorithms in a fun style. From QuickSort vs Bubblesort to Einstein’s Special Relativity, it’s a great collection of animations.
