The other piece of this, it occurs to me, is that while diodes and transistors and other semiconductor devices do provide new ways for circuits to react, they are nonlinear whereas the memristor is a linear device, just like a capacitor, inductor, or resistor.
I think you were on to it with your second point about it being basic because every circuit has some amount of each fundamental element. I've actually seen this a bit in resistance measurement stuff where bipolar excitation improves the accuracy of the measurement due to this effect.
The abstract of the original paper from ieee.org:
"A new two-terminal circuit element-called the memristor characterized by a relationship between the charge q(t)equiv int_{-infty}^{t} i(tau) d tau and the flux-linkage varphi(t)equiv int_{- infty}^{t} v(tau) d tau is introduced as the fourth basic circuit element. An electromagnetic field interpretation of this relationship in terms of a quasi-static expansion of Maxwell's equations is presented. Many circuit-theoretic properties of memistors are derived. It is shown that this element exhibits some peculiar behavior different from that exhibited by resistors, inductors, or capacitors. These properties lead to a number of unique applications which cannot be realized with RLC networks alone. Although a physical memristor device without internal power supply has not yet been discovered, operational laboratory models have been built with the help of active circuits. Experimental results are presented to demonstrate the properties and potential applications of memristors."
Haven't we experienced problems with small fibers in the body before causing all kinds of long-term problems (asbestos)? A lack of toxicity is one small step, but is there any data on long-term exposure?
According to the article, she is just moving on in a different direction, and will still help the OLPC project in her new capacity by providing parts at cost.
Please note that Barack Obama is also opposed to the Real ID, at least according to his voting record. You may or may not agree with him more on other issues.
I'm not sure I understand your efficiency assumptions for a typical nuclear steam plant.
A hot side for steam in a typical BWR of 1000K (1300F) seems kinda high-- I'd say more realistic is ~600F. The cold side for the steam cycle is typically going to be slightly subcooled water, maybe at 200F.
This yields about 30% efficiency. If you assume you're pumping 30 F water (about to boil) into the heat source, you get ~51%, using the carnot assumptions.
And that's just thermal to mechanical. You still have to turn that into eletrical which is going to ding you again, maybe another 25% of the 30%, then there's all the pumps and other losses, I think you'd be hard pressed to beat 20% plant efficiency.
He is the brother of the more notorious Rush Limbaugh [rushlimbaugh.com].
So dont be surprised that steve is issuing fascist rulings.
+3 Interesting??!?! You've got to be kidding me! Look, I am no fan of Rush Limbaugh, but a pure ad hominum attack on this person because he's someone's brother? That's just downright lame. Have we gone back to the Middle Ages in our reasoning?
My only thought at this point is, who should set the rules on what is acceptable and unacceptable for a developing child to see? I'm not talking about ages 8-12 or whatever.. but mid to late teens... are growing constantly at that age...
Yes, but isn't it wise to put the power of such decisions in the hands of parents? Parents can't be around 100% of the time, therefore its reasonable to expect a public environment that doesn't expose children prematurely to explicit content that their parents believe their kid isn't ready to see.
I really think the/.'ers on this one need to tone it down a little bit, on the whole topic of "Net Censorship". I can tell that many people who tout freedom of speech/information in the context of violence and pornography don't have children, because their arguments are mostly fallacious.
An common example is when they say, "parents should monitor a kid's internet activity." This is true, but what they fail to recognize is that is isn't reasonable to expect a parent to be in constant supervision of a child on the internet. It doesn't take too long to wander into some truly nasty shit on the internet (especially if you start talking in newsgroups), and there is little to no way a parent can protect their children from this and at the same time let them benefit from the resources of the web.
Anyways, back to the original discussion. If someone is going to say that video games are lumped in with movies (child porn), I say... NO SHIT they are! They are both forms of media that are capable of presenting sexually explicit and inappropriate (by most people's standards) content to minors! Of course they are covered under a similar law! It makes sense!
I really think people need to chill out and realize that the internet and computer domain are in DIRE need of some INTELLIGENT regulation. I am not talking about mind-control here folks. I am talking about reasonable and mandatory guidelines put into place to help everyone have a better idea of what they are getting into when they surf the net/play a video game. Information wants to be free! So let's find a way to allow our children to safely explore that world of information which we adults enjoy so much.

I guess that would be the free as in beer, not as in speech, philosophy?

Isn't this was some BSD developers were claiming was being done to their code in the Linux kernel a while back?

Is there a way? I'm sure there's a way. Although it doesn't seem to be very obvious.

Nuclear.
13? Yeah that's feasible at 13, but what about at the age of 7? Seriously, do you think that kids aren't aware of the internet until they are 13?
