Actually, he's just quoting the line that Fox says in response to Doc Brown. But seriously, you have an active Slashdot account! How could you possibly not know basic Back to the Future trivia like this?
I experienced this for my first edits, but this was corrected quickly once I started using the talk pages to back up what I was changing. Cite sources and give explanations when needed on the talk page and you will probably have a much easier time.
Maybe there was no appreciable benefit for having a larger flash storage. In cache, there are limits to how large you want to make the cache outside of physical or monetary constraints. You come into problems about the actual amount of memory that needs to be accessed at a time and the amount of time it takes to fill a block. If most of your data that you need has lengths of the two bytes, then it becomes less worthwhile to have a wide cache where you read in a block much longer than what is needed (you do not always want data in the same order as it is contiguously laid out in memory). This only concerns the width of the cache and is not a direct comparison to what you are asking, but it's been too long for me to gleam a better example. Having a large cache (or other lower level memory) is not very useful if you do not need to reaccess a lot of the data in relatively close intervals of time (temporal locality). In addition, the data you need may be located in many different areas in memory (spacial locality) requiring you to want to transfer smaller block sizes. Suffice to say, there are more considerations than just the size of your cache or secondary memories. The way in how memory is accessed and used determines to a large extent the size and configuration of the memory.
Well, we already moderate the comments so I guess we need to start moderating the tags. But then we need to moderate the people that moderate the tags because we already moderate the comment moderators. But then who moderates those that moderate the moderators? You know, this site wouldn't be so bad if it wasn't for the posters.
They also do local towns as well, but the project that I was on that used that naming convention was not a processor but circuit board. I don't know about you guys, but I really could have used a pamphlet about naming rules here. I guess that's part of the rites of passage for moving up to middle management.
Another way to describe the refractive index is in terms of the square root of the relative permeabilities and permittivities. In a negative refractive index, epsilon and mu are both negative. However, the refractive index is the square root of the product of these two. So they probably just retain the sign on the refractive index to show this important characteristic.
Basically all it means is that light is going to bend opposite of what we would normally expect. Instead of bending towards the interface, light will bend away from the interface. There's no fancy u-turns or anything like that. The negative sign is purely a consequence of the convention by which we choose our cross products when it comes to the vector form of Maxwell's Equations. Normally we use a right-hand convention, but a metamaterial behaves using the left-hand convention. This negative sign is one way of achieving the same effects using the right-hand vector convention.
What left-handed materials do is that it bends light in the opposite sense that we are accustomed. For example, if you place a pencil in a glass of water, the refraction of light will make the pencil appear shallower than its true position. If the pencil is placed in a left-handed medium, then the pencil will appear deeper than it actually is.
What happens is that left-handed (aka negative refractive index) materials will bend light away from the surface of the material instead of towards it. So making an "invisibility cloak" is not that hard. First off, to solve the problem of knowing where the eye is, you simply make the surface of the material symmetric. So for a three-dimensional object, the left-handed material needs to be spherically symmetric. They have produced an example in the microwave region for a cylindrically symmetric configuration. But the cylindrical symmetry means that the shroud will only work for certain polarizations of light.
So what happens is that when light hits the curved surface, instead of being bent in towards the center, it is bent outwards. If the refractive properties of the medium are properly tuned, what you end up doing is bending the light around the obstacle such that it leaves the medium in the same path that it would have without the obstacle. So the "invisibility cloak" works by bending light around and emitting it so that the light behaves as if there was no object. Since the medium is symmetrical, it does not matter where the source and receivers are.
For a true cloak to work will require a really neat feat of engineering because the refractive properties of the material must be constantly adjusting with the movement of the cloak.
Personally, I plan on just keeping Steve Purcell chained up in my cellar, trading food for successive pages of more comics. So it's nice to know that the episode format can be an enjoyable experience.
They're so glad that they're happy engineered mice. Alpha children wear grey. They work much harder than happy engineered mice do, because they're so frightfully clever. Happy engineered mice are really awfully glad they're happy engineered mice, because they don't work so hard. And then happy engineered mice are much better than the Gammas and Deltas. Gammas are stupid. And Epsilons are still worse. They're too stupid to be able to read or write. Besides, they wear black, which is such a beastly color.
Well, they took the UIUC sat down with them. Those guys are just down the hall from me. Maybe I should leave them a fruit basket or something. Still, that's the best excuse I could imagine why you would not have your final data for your thesis. "After years of research, design, and testing, our experiment was posed to finally give us data when it blew up. It was the Russian's fault."
And why the heck do you want to die when playing a game? I bet Monkey Island must have been a huge disappointment.
Oh but not entirely true. In Monkey Island 1 it is possible to find out
that Guybrush truely can hold his breath only for 10 minutes. Then the game became less sardonic witted swashbuckling adventure and more like bobbing and decomposing.
Since Fourier Transform is a convolution problem, we can also use FFT to solve problems other than timefrequency domain problems. In computational electromagnetics, method of moments involves integrating currents over Green's Function. This is actually a convolution problem and so we can use FFT to calculate the integration and accelerate our iterative solution. FFT allows us to go from order N^2 to order N log N. Depending upon our problem, we need one, two, or three dimensional convolution. So I could probably use their code to solve the case of the scattering of an EM wave from an infinite strip. And for our purposes it is preferable to have double precision as opposed to single

I'm sure Microsoft is going to drop bricks when they find out that users of other browsers bother to upgrade to new versions of other browsers.
And such a large number of pirates caused a reduction in the global temperatures, bringing about the Ice Age that ultimately created the fjords.
I'm as confused as you are. Why can't they just put them into units of Time to Read Library of Congress?
Obviously this one wasn't nailed to the perch.
It's not dead, it's resting!
