All the 3D cameras that use an array of 2D cameras, like this one does, have a huge fault. It is a big inefficiency and inaccuracy in aquiring the image. A large quantum mechanical loss of information of 99% to 99.9%.
The problem can be simply stated as that the camera is 4D, because it is a 2D array of 2D cameras, while the image is 3D. This means that the camera for a 3D picture of about 1000 pixels on a side must be 1000 times bigger than necessary, or have 1000 times longer exposure, or a combination of these.
SOLUTIONS: All solutions rely on making the camera 3D instead of 4D.
1. Take a short movie while changing focus on a 2D camera. Thus time in the movie is the 3rd dimension, translated into different focuses.
2. Make a camera with multiple 2D sensors placed at different focal lengths, and somehow transparentified, perhaps with half silvered mirrors. This more complex camera can shorten the exposure time significantly, if there is enough light.
A combinations of these 2 methods is often most cost efficient in money and exposure time.
Thise were old thoughts of mine, and I do indeed consider this to be prior art, and quite obvious as well. I also consider it to be evidence that I am better at this stuff than almost all 3D camera engineers.
If data are lost, and you do not have a backup copy, you can be prosecuted for negligence. If data are not lost, and you do have a backup copy, you can be prosecuted for stealing.
I have actually personally experienced both scenarios, but fortunately in a country that is less sue happy than USA.
The worst one, was when all the workstations were stolen, including backups. I and my colleague restored everything from personal backups, and thus the company was saved, and still exists.
Conclusion: Lawyers hate us and want to hurt us. The law is just an excuse. Time to make them obsolete.
The model linking solar activity to global warming is called "Black body radiation", and is over 100 years old now, and has always worked very well. Why do you find it hard to understand that if the Sun shines more on something, that something gets warmer?
And in a little while I will take a trip outside, where the cold snow make the same squeaky sounds under my feet as it did when I was a child, because it is now as cold as it was then.
I worked with this for 6 months. Learned a lot of interesting stuff about how people react to variations of emails. Short messages that are to the point works well, but so do some marketing tricks, such as scaring people, FUD.
Since the company was never satisfied, and wanted everything I did as their exclusive property, I used mainly multiple overlapping test groups with random sampling. I would have preferred advanced modelling, which I am really good at, but did not want to loose rights to do that. I later read some scientific articles about lipid research, and was surprised that they used much simpler and quite inefficient methods compared to what I did when demotivated. What a waste of human life. When I was in the oil business, they used modelling, but with only vague understanding of it, so I improved that a lot. And in all such cases, I got sort of fired. Does not seem like companies or organizations want such improvements. But they try to sell them anyway.
They code 2 bits into each base pair of DNA, which is the maximum possible. This means that some of the data will be instructions that the cell will execute.
I saw nothing of how to stop cells from executing the data.
As the author of Pentaput, yet another writing tool for the iPhone, I have some experience with the kind of problems with this concept. The main problem is that the friction on the screen varies a lot, depending on temperature and amount of finger grease on the screen. When slippery, it works quite O.K., but else wise, which is the usual, just touching ordinary small keys works slightly better.
I might find a solution to this, if I had the time, but I do not.
As a solid state physicist, my fast and sloppy guess as to how this works, is that the fourth thin layer that is visible in the picture, is a sort of stair step so electrons coming from that direction have to do two easy tunnelings, while those from the other side have to do one hard tunneling.
Just plant an encrypted memory stick. You can even hide it a little.
When the police finds it, and ask about its password, and the suspect acts confused, because he/she is confused and knows nothing about it,
they can then jail him/her for not disclosing the password.
Radiated heat, as in light bulbs, can heat more efficiently than ovens because
ovens typically heat the air, while heat radiation can heat the objects directly.
One instance of this I have seen, was factory workers working in cold air while being warm from heat lamps directed at them.
The crucial point that all these hysterical anti-rapists avoid totally, is the difficulty of knowing whether the sex is consensual or a rape.
After all, the defined difference is just in the head of the woman. Only she can really know if she wants it or not, and if this information is not reliably transmitted outside of her mind, it is simply not possible to know if it is a rape or not.
And the hysterical anti-rapists never ever tell realistically how people are supposed to know this reliably, while at the same time accusing people of knowing it and ignoring it.
This is logically inconsistent, and one reason I call it hysterics.
One cannot stop a rape if one does not know if it is a rape, whether one is a bystander or a rapist.
If IQ correlates negatively with work performance, then work performance is likely tested wrongly, like believing the number of code lines is a performance indicator, or number of stitches used in surgery, or number of patients operated each day, or amount of water used to stop a fire, or amount of stocks traded for a trader.
Intelligent people see through these false measures, and gets punished by mob and bosses for doing so, and thus registered as unproductive.
Programming and surgery is better when it is short and correct. Surgery is better if the patient gets better. Putting water on fires is better the better it stops the fire. The amount earned versus risk is the performance for a trader.
And the company is better if the bosses understand this, but they seldom do.
The point of using several antennas is to avoid using those that are blocked. It is also possible to steer the waves using phase/amplitude differences, to minimize loss and maximize gain.
And I thought that Apple had chosen the obvious solution (to me) of having 3 dipole antennas with the 3 gaps in the metal frame, instead of just one, which obviously will be covered often.
After all, having multiple antennas is a standard solution for signal problems.
But it is now apparent that they were too cheap to do this.

I'm curious to know the mechanism by which you, as a physicist, view hoarding as impeding progress.
Hoarding impedes progress by making people hoard lots of complex explanations, complex programs, complex laws, etc. instead of searching for the better few simple ones.
I'm a physicists too, but Ockham's Razor hasn't been proved, from Wikipedia:
---
In science, Occam’s razor is used as a heuristic (rule of thumb) to guide scientists in the development of theoretical models rather than as an arbiter between published models.[4][5] In the scientific method, Occam's razor is not considered an irrefutable principle of logic, and certainly not a scientific result.[6][7][8][9]
---
I've actually had a good look and Ockham's Razor from the point of view of information theory. See, my blog. The trouble stopping the Razor been robust, is finding a fair language to express the scientific theory in a minimally small way.
As you apparently know, the change in probability from changing representation language is maximally 2^-+c, where c is the size of the smallest program simulating one language with the other.
However, this is an upper bound, and the real difference in probability will in practice be much smaller than this, except for some weird languages. Cellular automaton No.110 is universal, and extremely simple, so c must at worst be the complexity of this.
Solomonoff made some bounds of how fast systems like this can learn, and it is VERY fast. In this case, it is the speed which one language can learn another, and this can be much faster than c.
I can tell that the problem is a lack of Ockhams Razor:
The probability that a theory predicts correctly, gets higher when the theory gets simpler.
The probability that a program is useful in new situations, gets higher when the program gets smaller.
This has been proven mathematically with algorithmic information theory.
However, Keeping It Simple, Stupid, is very hard and costly, and most people have an instinct for hoarding that gets in the way.
Nowhere do coastwalkers post contain climate science.
Instead it contains conspiracy theories.
This in itself is a sign that Anthropogenic Global Warming is false,
since if it were true, coastwalker could have brought evidence instead of conspiracy theories.
Absence of evidence is evidence of absence.
This has been proven mathematically.
Stuff like this is an attack on programmers from people with lawyer education.
We damaged or destroyed the music industry.
We could do that to lawyers and judges as well.
Considering their general low quality, they could in most cases be replaced with simple machine intelligence and data mining.
Do this with open source and collaboration, and they will be displaced just like peopled stock exchanges.
Of course there will be a transition period, but when computer guided actors playing lawyers in court rooms win significantly more cases than real lawyers, and computers are better at judging than judges, people will treat them as the obsolete guild they are. The survivors will be lawyers that understands computing.

Hi Arrogant ignorants.
You have failed to understand anything at all.
A was writing about transparent sensors, and I see from how I wrote it that it takes an idiot to misunderstand that.
And yes, I can indeed capture 3D with only one camera. I will likely put this project on my web page some day, along the other projects.

If they are not able to enrich uranium themselves, then they are certainly not able to take care of the spent fuel, which is much harder.
The idea of renting out whole self contained reactors is better, because they can be returned intact.

It cannot possibly be faster than O(n^2) in the general case, because the size of the matrix is O(n^2), and each element has to be read at least once.
