The brute force solving of problems can be very useful. The scientific method relies on theories, and having ample data to look at helps people understand complex systems, sparking the intuition that leads to more theories, and hopefully, more elegant solutions. I've worked on the optimization of large systems, and nothing helped me understand the processes involved as much as "brute force" simulations.
Didn't we just have an article recently about a CPU cooler that used a similar concept, except in reverse. I can't find the reference, but I remember reading about a tiny solid-state electrostatic pump that could pump 20 cm/min of an electrolyte solution at 2 bar just by applying a potential across a porous ceramic material. Ring any bells with anyone?
Explanation: Jon Burnett, a teenager from South Wales, UK, was photographing some friends skateboarding last week when the sky did something very strange. High in the distance, a sofa-sized rock came hurtling into the nearby atmosphere of planet Earth and disintegrated. By diverting his camera, he was able to document this rare sky event and capture one of the more spectacular meteor images yet recorded. Roughly one minute later, he took another picture of the dispersing meteor trial. Bright fireballs occur over someplace on Earth nearly every day. A separate bolide, likely even more dramatic, struck India only a few days ago.
This is off-topic, and not picking on anyone in particular, but I was wondering whether there is a name for when someone brings up slavery to make a point. Kinda irks me when people who have no idea what it was like back then use it to explain something to other people who also have no idea what it was like.
It seems that for the nanoturf to work, there needs to be air surrounding the spikes so that a minimum solid-liquid interface occurs. If you attempt to use this principle with a submarine, the air pockets are going to shrink significantly as depth increases. Also, corrosion loves pointy things.
OK, it's good that you're not doing it alone, and it's good that you're not aspiring to make a product out of it. For teaching purposes, you guys don't need to worry about accuracy or rigor, just something that converges, so I think you have a feasible project, as long as you don't attempt anything large. I wish I could send you some useful links, but I really haven't found that many myself. I'm going the nonlinear, rigorous, equation-oriented, DAE route, and there's not a lot of available code for that lying around. I gave up trying to base my stuff on existing code anyway and I'm pretty much rewriting everything from scratch. Do you guys have a web site yet?
I'd like to encourage you on your mission, but I get the feeling that you're a college student with more enthusiasm than experience. I'm working on a chemical process optimization system myself, so I know what size an undertaking it is. I've also worked in the field for years, so I also have an idea what goes into making this kind of software. So, before I ramble on, what's your background?
I wish I could tell you the difference between the two, but I'm just now looking it up myself. Obviously, we've "detected" objects much, much, much further away. Even more importantly, we even have "Artist's Depictions" of those too!
If these guys, or any other guys, had developed some incredibly complicated nonobvious process to make an anti-HIV drug, I would say that they were entitled to a patent, and riches. Since they just figured that an existing thing does the trick...eh...not worthy of monopoly status, maybe good for a Major Award though.
I've got a pretty old mouse to enter in this contest. It's a MS Mouse, serial number 0002224, circa 1983. Five years old ain't nothing! Any challengers?
Staying focused on something that you don't enjoy is called self-discipline.
Baloney. This is the biggest disconnect between people with ADD and those without it. More effort does not lead to more concentration and enjoyable tasks don't guarantee focus either. It doesn't work that way. Sure, "normal" people experience trouble concentrating on mundane tasks, but magnify the effect by ten and imagine what life would be like for an ADD'er. Most people understand the concept that there is a large variance among people when it comes to math, verbal, musical, logical, athletic, and memory skills, so why is it such a stretch to imagine that people's ability to organize, pay attention, or avoid distractions are just as varied?
Awesome! I have a dinosaur egg that I'd like CT'ed, just in case there's something interesting inside of it. My dentist's X-ray machine isn't powerful enough to resolve any details. Thinks they'd stop by my house for a visit?

The more efficient types of windmills like the cyclogiro (gyromill) or Darius designs are more mechanically complex and require more maintenance than the simpler propeller-driven ones seen in the picture. They aren't banned, they've just been BetaMaxed. It's also hard to place them high up in the air where the wind is really blowing. It's a pity too, because these designs tend to be a lot quieter.
...better safe than sorry...better safe than sorry...
Let's take a poll. Which do you think is safer, talking while flying (subliminally think of terrorism now) or talking while driving? Let's give the people one more thing to fret over. Notice how the report states that phones are "a threat" to airplanes instead of something reasonable like "they might interfere on occasion". If phones are setting off smoke alarms and messing up compasses, chances are they're flying over the Bermuda triangle anyway. Look, I'm talking on a cell ph)ne r1ght n0w,, and no7hin9's hap.
To get the highest heat conductivity that you can from diamond films, you need to use isotopically purified carbon-12. Taking out that 1% of carbon-13 improves the conductivity by about 40%. Considering that normal diamond film has four times the thermal conductivity of copper, that's a lot!
Companies already exist to diamond coat objects up to 12" across and 1.5mm deep, so it can be more than "atoms thick" if you'd like. Here's a couple places that do it: Diamonex. P1.
An example of a high dimensional graph would be a 3D grid of vectors, such as a weather simulation. The little arrows would appear distributed in 3D, but they could also have attributes of direction, length, and color. Obviously, they're not true dimensions, but each datum conveys a lot of info (X,Y,Z,dX,dY,dZ,T).
The phrase "inconstant moon" appears next to the picture in the linked article. If you've read the classic Asimov short story with the same title, this is the last thing you'd want to see. Go read it.
I've got a degree in chemical engineering and one in computer science. What does that make me? That makes me an engineer who's also a programmer that understands computers well. The degree of difficulty between the two is significant, and I think that should make the term "engineer" signficant. I'd no sooner call myself a Software Engineer than I would call myself a Reading Engineer, Writing Engineer, or Arithmetic Engineer.
How about using a larger sample of code before making such bold statements. It's probably true that the code has fewer bugs, but when you abuse statistics it just makes things look dishonest.
My 20+ years worth of non-licensed troubleshooting is far better than any certification, in my opinion. I routinely fix systems that I have never seen before just because I have a knack for it. I think certification is great, but not necessary.
What are we going to discuss next? How about "should all programmers have CS degrees?".

Why is it labeled "nano-tech"?
Cracking diamond is no big deal. Does it scratch it too?
Dorks. A hard form of graphite will not be used as a structural component.
No mention of hardness measurements (Mohs, Rockwell, Knoop).
Sorry for the rant, bad science reporting irks me.

Wow. That doesn't seem like much. They must have had a lot of self control. I would have poured a lot more than that into a pipe that big.

Amen, I drink Diet Rite all the time, when I can find it. Another drink without aspartame is Diet RC cola. It uses sucralose too.

Clearly, they planted the evidence...

Wow, with a seven-year gestation period, it's no wonder they went extinct.
