You can test objects with a crossection of up to 12.1x24.4m^2. The_major_drawback is the maximum test speed of only 51m/s. Today, the big shots are tunnels which can do transonic speeds (up to Mach 0.9, or app. 300m/s). They are not full scale (it'd have power requirements in the order of_thousands_of megawatts). Every and each plane developpded by Airbus and Boeing is being thoroughly tested in tunnels. They are still needed, and will be for a while. Numerical methods only go so far and are mostly used in the early aerodynamical design phase. Polishing is always done in the tunnels because in order to obtain the precision needed to simulate an entire aircraft in 3D you'd probably need the power of a few hundred NEC "earth simulators" (no, I'm not kidding, that's what I do at university). By the way, the only tunnel I know of which is capable of simulating transonic flight (Reynolds numbers of 50e6 and above) is the European Transonic Windtunnel (www.etw.de).

What do you mean, 2.2? Seriously, the "server" in my parents not-so-small medical cabinet connects to 5 serial terminals and a couple of printers and card readers. I set it up in 1998 (downgrading from SCO;-) and it's been running ever since, litterally 24x365. Not one single crash. It runs 2.0.35.
Sorry, but the dimension of "the square root of Pi, times the gravity divided by the distance the pancake is from the elbow times four" equals the angular_acceleration_and not the angular_velocity_! Do the math;-)
Amen brother! Respecting some simple rules, you can quite easily secure your Linux box:
* Password protect your BIOS * set up Lilo to not allow "boot: single" (easy) * as opposed to other comments, ordinary users can't mount other partitions on the same system unless they are explicitly mentionend in/etc/fstab * home directories should be "chown 700" * physically secure your machine with a lock and/or intrusion detection.
Accidentally, there's the World champion ship in handball running right now in Portugal. American football isn't all that uninteresting, but still, if you get the chance, check out handball. It compares a little to basketball. It's a_very_fast game and we Europeans (including, taditionally the strong East European countries and recently South-East Asia) are really excited about it.
As a student of mechanical engineering I'm still amazed by the sheer mass of educational material available online.I'm not talking about silly Java or Flash-based applets. Need a good course on numerical analysis, linear algebra or aerodynamics? You name it, it's all there, mostly in pdf, which is easy on the eye when reading on your CRT. Furthermore, free tools like gnuplot, mupad, or even the ODE-solver in the plotutils-package will oftentimes save your day when trying to grasp complex mathematical concepts. For elementary or even high school though,I don't think these teaching concepts have had a big impact on education yet. Explaining trigonometry to a 16-year old probably works better on the blackboard.
Scientists not long ago reported that we might be on the edge of a new "micro ice age". In a couple of years (maybe in 2007), the Gulf Stream might crawl to a halt, thus no longer providing warm water to the Northern hemisphere. Seattle might freeze over and Microsoft would be releasing Server products running natively on Linux... Oh well, nerver mind.
It's a common misconception that mass depends on gravity. If you took a balance to the moon and put one kilogramm on either arm, you'd still find that they're identical. What does depend on earth's gravity is the *force* each heavy (i.e. non massless) object is "drawn" towards the hypothetical centre of mass (F=mg).
Let's see: * power plant efficiency: nuclear ~28%, charcoal ~35%, modern gas-steam-processes ~57%; now mix it -> ~35% for the complete mix; we don't consider wind, solar and water powered plants as they only contibute around 5% to the complete mix. * ~90% efficiency for getting the current to your wall socket * 90%*35%=31.5% * add the efficiency of your car's AC/DC-converter and the batteries and electric engines effieciency: about 90% each. 90%^3=73% * multiply: 31.5%*73%=23%
Thus about 23% of the "raw" energy is actually getting to your car's "crankshaft"!
Modern Turbodiesel engines have a *total* efficiency of well over 40%! You do the math. Get yourself a VW-Rabbit or a Peugeot 306 (Diesel, of course). Better for the environment in any case. *Plus* you can make it run practically *any* sort of veggi oil: nut-oil, corn-oil, you name it! Biodiesel too, of course.

OK, moderators, we've obviously got some smartass here who hasn't got the *faintest* idea about football. I'm a little dazzled, and maybe I misread his "+3 insightful" as "flamebait" where it should have been "troll". But I'll bite anyways. Any moderator who hasn't seen the match shouldn't, well, moderate. This comment is so full of crap that I don't even bother to step on the soapbox in order to tear his analysis of the match to pieces. I'm ready to discuss this, I admit, somehow "offtopic topic" with anybody who'd like to engage, but please, PLEASE, don't moderate this to +3! Anyone who has a 101 clue about football, please metamoderate!

Ok, did anybody actually realize the following:
single: 4m:51s = 4x60s + 51s = 291s
dual: 2m:00s = 2x60s = 120s
291 / 120 = 2.42 = 242% !!!!
Thus, the dual system runs an amazingly 2.42 times
faster than the single one! Doesn't take an engineer...
Come on, mod me down.
Ok, girls. This train is built by a german consortium. It exceeds 500 km/h in speed, and obviously China must have examined their options before jumping on this project. The biggest problem, btw, is the noise produced, which is proportional to the sixth (!) power of the velocity. Furthermore, germans are bloody ecological bastards who block about any new technology. That's why it's first realized in China.
For anybody who cares: You should definitely take a closer look at http://www.imm-mainz.de. I've visited them once, and boy I _was_ impressed. They built the smallest helicopter, nanocatalysators for the chemical industry, and, of course optical switches and multiplexers. Definitely worth a look.
