Scientific Imaging: The Art Of Data

Filed under

Thin orange and blue lines swirl above a surface of colored cones, outlining a hollow cylinder. Suddenly a cluster of red dots gathers in the middle of the cylinder, spinning around furiously and gathering force with each rotation.

The image is abstract, but striking: The red dots, we soon learn, represent a T3 tornado (tornadoes are rated between T1, or "Light Tornadoes," to T10 "Super Tornadoes"); the lines, airflow geometry in and around it. The cones represent wind speed and direction at the ground. The hour-long process of a storm's formation has been depicted in just over a minute. (Click here to see a video of the simulated storm.)

Aided by advances in computer graphics and animation, scientific visualization has grown increasingly sophisticated over the past five years. Forget about those tinker-toy-like atom models from high school chemistry. Nowadays, complex computer-generated images of cell structure and anatomy are used to teach medicine, and computer animations can model everything from melting polar icecaps to protein synthesis. What was once a very traditional field is in the throes of a digital revolution.

It's a booming market, too. According to Machover Associates, a White Plains, N.Y., computer graphics consultancy, the worldwide market for scientific visualization in both two and three dimensions is expected to grow from $10.7 billion in 2005 to $17.2 billion in 2010. Most of the money is going into 3-D imaging, according to Machover, and although the majority of it will come from private industry, a substantial amount of federal research funding will be channeled toward that area as well.

Mozilla Firefox 32 Officially Released

It's been a little over a month since the previous Firefox stable release and the developers have now pushed a new major update to users. This latest iteration of Firefox brings just a few major features for regular users, but it excels in other areas like better HTML 5 support. The official announcement for Mozilla Firefox 32 hasn't been made public just yet, but the mirrors now host the latest stable versions. It will take them a while to post anything official, and some time may go by until this new release hits the repositories, but you now can get to see what has changed. Read more

Time For the GNU/Linux Desktop

M[icrosoft] has deliberately violated the laws of competition in USA and elsewhere repeatedly, systematically and with malice. They are out to get us. At first they got an exclusive deal with IBM to get their foot in the door, piggybacking on IBM’s branding with business, then they demanded exclusive deals with ISVs and manufacturers, then they punished any manufacturer who stepped out of line and installed competing products, then they created an endless chain of incompatible file-format changes and created whole industries based on the existence of overly complex secret protocols and finally forced the world to accept a closed standard as an open standard… That whole burden has served to render IT more expensive to own and to operate and much more fragile than it should be just on technical merits.

5 tips on migrating to open-source software

Open source is not just for Linux. Yes, you'll certainly find a much larger selection of open-source software for the Linux platform, but both Windows and Apple also enjoy a good number of titles. Regardless of what Free Open Source Software (FOSS) you need to use, you might not always find it the most natural evolution -- especially when you've spent the whole of your career using proprietary software. The thing is, a lot of open-source software has matured to the point where it rivals (and sometimes bests) its proprietary counterpart. Read more

A web browser for the Raspberry Pi

As I previously mentioned, Collabora has been working with the Raspberry Pi Foundation on various projects including a web browser optimised for the Raspberry Pi. Since the first beta release we have made huge improvements; now the browser is more responsive, it’s faster, and videos work much better (the first beta could play 640×360 videos at 0.5fps, now we can play 25fps 1280×720 videos smoothly). Some web sites are still a bit slow (if they are heavy on the JavaScript side), but there’s not much we can do for web sites that, even on my laptop with an Intel Core i7, use 100% of one of the cores for more than ten seconds.
