No, Mathematica has had LaTeX output capability since version 1. (See TeXForm) (In addition to a handful of other output modes such as MathML, CForm, etc).
Several months ago I read somewhere that Mathematica 6 has a completely rewritten front-end that is based on Eclipse.
I for would welcome a new notebook interface as the V5 interface is sub-par by modern standards (e.g., no anti-aliased fonts).
For the record specialized applications for data visualization (VTK-based etc) can be connected to a Mathematica kernel using MathLink or J/Link over the network.
There isn't any reason why all of these variables can't be taken into account. Then again, if he did that he would be a statistician, not a mathematician.
No, that isn't it either. Technically, if the mind's organization system is internally random, then it does not matter if it is interacting with a system that is random or ordered, because it sees both as random. An ordered system cannot be any better or worse than a random one. (*)
The real truth is that a messy desk is actually a vertical FIFO sort -- most recently used thing on top. Now I myself am a very organized person, but I also know that FIFO sort is basically the most productive organization strategy for human-scale things. For example, in the front 3 inches of my filing cabinet I keep folders for about 95% of the paperwork that I need to deal with on a semi-regular basis. The only difference is that I decided these papers don't need to be scattered over a broad flat surface in order to be easy to find. I've also found that if I keep those same file folders in a more "proper" place, e.g. alphabetized, etc, then I simply won't file away papers because it takes too much effort and a big mess results. By the way, all productivity experts know about the FIFO system and recommend it (e.g. David Allen).
Finally in TFA they estimate people spend 1-4 hours per day cleaning (including home life), which is basically a highly pathological case, at best. Someone who spends that much time cleaning is either OCD or a janitor.
* In some creative processes it is advantageous to have a random and independent sampling strategy over the materials you are working with. But people tends to processing things in linear order, so independence is violated when going through a sorted pile. Thus certain types of things are good (and fun) to have disorganized, like art supplies. However, I would argue that for most "productive" people, creativity and random-association isn't a big part of their job.
Most technical jargon has very precise semantics and can't be transcoded into "laymans' terms" without an absurd explosion of verbosity that ultimately takes more time to wade through than just learning the technical vocabulary in the first place.
However, speaking as an applied mathematician, I look for a list of applications of a concept. Since this is basically informational content it is readily found on Wikipedia or elsewhere and typically vastly easier to understand than the concept itself. Given that information I can determine if its worth the effort to actually learn it. This sort of information can also be found in books like Hyperspace, and IMHO, is also just about the only real information they contain other than some historical details.
There are a couple other brands, I forget what they are. Futaba? I guess the servos I've used are just not that powerful by comparison because they are nowhere near as loud. Judging from the video, that thing sounds like its positively screaming.
On the contrary, its a huge leap to assume that they *did* understand the math just because they had the tiles. Basically all the mathematical properties of the penrose tiling (e.g. relationship to the golden mean, group-theoretic results and so on), are completely irrelevant to the actual act of discovering and assembling the pattern, which can be done by anyone with sufficient motivation and attention to detail. Now everyone would love to jump in and say "what if"... because its fun to do so, but its just looking for the missing elephant behind the sofa. The mathematical knowledge would be documented much better elsewhere.. like, in manuscripts... about math... and stuff.
The significance of TFA is the discovery of the method they probably used to actually make the tiling work on a large scale -- by sketching out a template of large scale "meta-tiles" to guide the placement of the smaller ones. Otherwise, even if you have the penrose tile set, small placement errors eventually accumulate and ruin the pattern -- and *that* is what has baffled people for so long about how they did it. The technique clearly shows certain sophistication and that is impressive, but its purely a feat of architectural engineering.
Can we run a search engine backend over P2P/bittorrent? There is no shortage of hardware if its distributed. At least, the SPAM-bot networks don't seem to have a problem getting enough bandwidth.:)
The sensors in the wiimote are nothing new, nor are 3d controllers in general, but their particular combination makes it a reliable solution with a reasonable price point and practical to produce on a large scale. A lot of earlier approaches to making 3d controllers had problems, e.g., interference of various sorts (acoustic / ultrasound or radio), high cost, or large detector arrays.
FWIW there is already a driver for OSX that reads the wiimote's bluetooth data stream. But that does not include the Wii's sensor integration algorithms (e.g. combining the accelerometer with the IR sensor), which are probably similar to the algorithms used for integrating intertial guidance systems to a GPS. Also, it seems insane, but the actual gestures used in gameplay can be patented. Nintendo will probably be able to defend themselves from knockoffs at least for a few years. Similar things could be said of Apple and what they did with the iPod interface (and soon, the iPhone as well) and they have been pretty successful at preventing knockoffs.
The other thing about the wiimote is that its actually not much good for applications outside of gaming (IMHO) -- for example, users of 3d editing applications prefer 6DOF controllers that stay on the desk -- one for ergonomic reasons, but also that in general a human can achieve a higher resolution of control using an interface without proprioceptive feedback. This might be why no-one outside of the gaming industry has bothered to invent and patent something like the wiimote already.
Paradoxically, many of the same people who opine against urban sprawl are also against high density and high-rise housing complexes. The politics are convoluted enough to give one a headache.
Shouldn't they have disclosed that it contained latent n capability in the first place? I mean, even if it is disabled, it is still *there* and the job of accounting is to describe exactly what is there, not to mention keeping the paper trails consistent which must have already mentioned the n feature at some prior point.
IMHO, they screwed up and are now using a technical loop-hole to avoid being fined for a material misstatement. Worse, they found a way to turn the loop-hole into profit. Even worse, they probably did it on purpose because it would have been an embarrassment when the mac-dorks discovered the hidden n functionality by reading the financial filings and some 15 year old hacker came out with a kernel patch to enable it before they did.
There are PDAs for blind people -- the ones that I have seen have a chording keyboard and a console-type interface consisting of a few lines of braille. They can do normal PDA type stuff like basic calculator, take notes, etc. They don't look very flashy though, its just small gray box with buttons... maybe for obvious reasons.:)
I don't think they are the same at all. Corporations have a plethora of legal protections that afford its members a position of power, and that power needs regulation. Furthermore, corporations have narrow interests -- specifically, to profit by conducting business. Business transactions are regulated by contract law. But, since a corporation exists *only* for the purpose of engaging in contracts, it raises the question, what part of corporate speech is *not* covered by contract law? For example, in determining a case of misrepresentation, statements of opinion are generally not considered. But a corporation is a fictional entity. It does not have opinions, so why should we protect its ability to state them?
People have diverse interests and needs, corporations (and people while acting on their behalf) do not.
I suppose that the falloff is not uniform because the wavefronts don't quite propagate circularly from the epicenter, but rather from a distribution over the faults (who's mode is the epicenter).
Linux wins on installation flexibility, hardware flexibility, and esoteric kernel tweaks. And for stability and ongoing maintenance of long-uptime server systems, it absolutely rocks. But for a desktop system, no thanks. Better than windows but there is no way I'd give up OSX (and I used a linux on the desktop full time for about 8 years (mostly Debian/Gnome but also KDE in the early days) before I "switched").
Not to say that OSX is perfectly consistent. I've found problems before -- for example as a dvorak typist I found several places where the "qwerty assumption" caused the keyboard layout to be violated. I filed bug reports on them, and on the next release found them to be fixed. Some people may not realize this but Apple actually drives a significant portion of their maintenance effort on the basis of bug reports. In fact some of their engineers are not allowed to work on things that don't close reports. So if you care about it and it affects your work, don't just sit around and gripe, file a report.
Its both quieter and cooler than any other computer I've ever seen (not including that insane Zalman thing). No whine. Fans kick in if I launch a big compile but even then still less noisy than my 2x2G G5 powermac. Not to mention faster.:)
Indeed, the NN/MLP is just a function interpolation algorithm, and not even a particularly good one at that -- it has a lot of problems that are fixed in more modern algorithms such as the SVM / kernel methods.
If anything I suspect that ensemble algorithms like MCMC, importance resampling etc are probably more similar to how learning actually takes place in the brain.
Just so this post does not go totally off topic, I'm fairly certain Scott Adams is not the first person to recover from this affliction, a couple years ago I heard an NPR special (I think) about someone else who did -- he was a professional storyteller (talk about job function impairment... yikes).
I plotted that and it does not oscillate. (Mathematica 5.2).
FFTW does 3D DFT also.
Looks like when is now. They also added transparency and volume visualization.
I'm going to have a very hard time convincing myself to put up with Matlab for anything now.

Good point. Whether or not having kids should be considered "productive" is apparently a topic of ongoing debate.

Yeah, that and the ones in my gym also have variable inclination from 0 to 12 degrees and programs to cycle through the different angles and speeds.
That said, I much prefer running trails in the local park. Not only in the terrain more varied, but its damn beautiful, even when the weather sucks.

It seems to modulate sometimes when the robot flexes... is all that noise from the servos? What causes it, and why is it so loud?
