The picture on Wikipedia represents electron wave functions (with brighter spots corresponding to higher probabilities densities of the electron position). This ias a "static" (=time-independent) representation.
Spheres orbiting spheres is a time-dependent representation. Note, that electrons still do fly around protons.
I think, this confusion between electron orbitals as wave functions (time-independent) and as particel movement around a center (time-dependent) is very popular, even under academics.
I can vaguely remember some Hugo or Nebula awarded SciFi short story, which was exactly about self-replicating machines. Too bad, I can't remember the name.
Story goes like this: three men sail to a lonely island somewhere in the caribic. One of them is a researcher (the "doctor") carrying huge boxes with him. Boxes contain self-replicating machines (the "bugs").
First, the bugs will only use sunlight as energy and metal provided by the doc. They will simply freeze in the evening and only continue the next morning. But you can already notice small modifications in newly built machines (evolution)
One day however, the doc feeds the bugs with a special metal (cobalt) ant they begin to use _every_ metal available to construct new bugs (including other bugs), which leads to cannibalism. They find a way to be independent from sunlight.
Evolution however goes the "wrong" way: instead of smarter bugs, only bigger and bigger bugs are created. The last scene if the last bug (huge like an ox) running after one the men to catch his marriage ring...
For 3 years now, my salary has not increased but diminished. A whopping 15% reduction in the whole year 2004 will eventually be reverted by 2005.
Has anyone similar experiences?
One addition: A380 can carry 555 vs. 524 of the 747 in the standard configuration. But while the A380 has 50% more room than the 747, it uses only 35% of it. The remaining 15% makes for wider seats.
Well, the A380 can take 555 passengers in an average configuration, when they go to cattle-carrier mode, it can take up to 840.
What I've heard last, they are planning a 1000 passenger variant. Hmm...
Wow, I'm really impressed. Together with Google Scholar, this will lift academic research considerably.
Now if they only could contact german libraries like "Bayerische Staatsbibliothek" http://www.bsb-muenchen.de/, too....
Hmm. Does interfere with FireFox autocomplete

Now google interferes that with queries, I don't want to submit.
Journalists often think, a correct, but therefore "onesided" article about a scientific fact/discovery etc. is too boring.
So they introduce an artificial "controversial" that doesn't exist in the first place. E.g. f a "controversial" scientific topic has a 98:2 ratio for one side, you will still read about the remaining 2 percent who have a different opinion.
Microsoft uses a nice analogy... from the analogous world. In the digital we live in and where Microsoft has its business it is completely wrong.
Everyone can make "compatible" shoelaces. I can do it, you can do it. A better analogy would be, if Microsoft constructed their shoes, in such a way, that no other party could produce compatible shoelaces.
It is the closedness of their APIs, not the bundling of the Media Player, which made the EU perform its actions.
While I think that assembler (and in general low-level languages) are neglected now in favor of high-level concepts, learning about a specfic computer architecture is definitely not enough.
It is a well known fact, that most times a clever application architecture or algorithm is far more efficient as any low-level optimization (think 'quick sort').
A balanced approach between low-level concepts (assembler, programming on register level, knowing what pointer arithmetic can be good for), datatypes and algorithms and high-level concepts (modeling and higher OO languages) is needed.
What engineering teams needs often most, gets sometimes not taught at all: project management, requirements engineering, team communcation, testing (and so on..)
Hmm, I always thought, that the first three films were great for different reasons. Each of the directors (Scott, Cameron, Fincher) had a unique vision of what "Alien" means to the viewers at their time. The 4th film was a big let-go, especially the schmaltzy end. It simply lacked a vision, of what it wanted to be.
I think it was meant to be "post-modern" but its pieces didn't fit together.
Until 2 weeks ago I had a Genius 3-Button Mouse. I never was 100% sure, what mouse-protocol would work in Linux or what mouse-driver I should use in Windows, but somehow it worked nevertheless.
A former girlfriend told me, that all laboratory mice and rats are descendants of mice which develop cancer after some time, cutting the normal life span of that animals to a half.
Could that be true? Now this longivity contest would remedy the malice, it introduced beforehand.
We have an application, that recently underwent a major GUI update. Unfortunately, we had to drop an old and seldom used feature.
Now older clients would loose information, if they had used that feature. So we developed some filter via XSLT (which is builtin in our application now) to migrate that info to XML, that is OOo and M$ office formats.
Says the Iraqi Information Minister.The fact is that, thanks to it's use of garbage collection and because it stores non-primitives on the heap, Java will always be _significantly_ slower than C/C++, no matter whose JIT you are using.
Have you ever looked out for machine-compiled Java code? I know of atleast two virtual machines/Java compilers, that do that: AICAS and PERC. They also feature incremental garbage collection and other goodies, wich reduce memory and startup time and make things really fast.
M.C. Escher played a lot with distortions and multiple perspectives. I remember one ultra-cool graphic, where you look simultanously at a couple of houses from the bottom and from a position above.
What is the ceiling of one the houses from one perspective is the floor of the same house from the other. This made me crazy everytime, I looked at it.

Google said: Don't be evil.
They didn't say: Don't be annoying.
But what, if annoying is felt as a bit like evil, too?

The scary part is, that the parent is modded "Insightful", not "Funny".

Embedded != Embedded. MS products maybe used in cars, but largely in the "infotainment" sector.
WinCE is much too big for the tiny microcontrollers that control engines, breakes, gear shifts and so on.. As is Java.
If you want to really what going on in car electronics look for example for the OSEK/VDX initiative, a consortium of german and french carmakers.
I'm a true slashdot reader, but I don't like ASCII "art". Who came up with this nonsense, anyway?

Uh-uh. I don't tip.
