Technically yes but what I mean is: Are there organisms that shape that sound into a tightly focused beam, to be able to only address the receivers they aim at?

What single-mode lasers do offer is a means of inconspicuous communication. If you can aim your communications channel at a receiver, you cannot easily be detected. But life could do similar things with collimating reflectors, even for soun

From my perspective I think the EU/UK talks have gone nowhere because the brexiteers didn't have any strategy at all. It boils down to playing chicken and thinking the rest of the EU will flinch at the threat of the UK cutting all

I don't want to read anything into this that wasn't intended but are you saying that society should be harder (crack down) on homeless people but not on other disadvantaged people?

Diffractive lenses exist for that (Fresnel zone plates are being used for that) - the problem is that they're absorptive diffractive lenses instead of phase masks and of course they have limited manufacturing precision. It's a con

Look up Fourier Ptychography, i.e. like this presentation by Guoan Zheng [0]. Fourier Ptychography is basically a variation of Gerchberg-Saxton phase retrieval in the sense that both methods and their variations reconstruct images from cons

So what does that mean for US companies sending packages into countries that are part of the UPU (Edit: virtually all countries on Earth)? Can each country now refuseand set their own rates for transporting US parcels the last mile?

But it would have happened. The Sovjet Union had developed an automated retaliatory system, named 'Perimeter'. In the case of an alarm, it would have given the government executive the option to flip a switch and activate the syst

I think I've seen a rather pragmatic hack that has been used in Google Earth for their stitching of terrain: They simply add a kind of skirt at the boundary of each square chunk [0], so that there aren't any white/black pixel

It's a very interesting technology, especially since it holds the promise to directly realize an almost arbitrary phase-mask (analogous to a lens' shape) that has been found using already existing optical design technologies. The

It is rehab, I've been there and had to drive around it to get to the vantage point. Edit: The pit looks like some lunar surface from one of the vantage points - it's wide enough to be larger than your field of view. Also, I'

I wonder whether the lack of replies is due to lacking first-hand experience of the HN community or if it is due to the difficulty of making that jump. Nevertheless, I also would be interested in any anecdata surrounding this.

Also, if you rebuild a system in isolation, you have to reproduce all the bugs - since you do not know which of the bugs are load-bearing, i.e. other systems have been engineered to depend on the bugs, whether by accident or intentionally.

They have their disadvantages though, since the angles between incident light and surface are only mostly preseved in practice: e.g. scattering from single facet radii (due to limited manufacturing precision), the necessity of draft facets

You can count rings of a tree you cut down - if you have a system for relating/storing their planting time deltas then you can measure by cutting down a tree and planting new ones. Edit: Apparently, together with climate data you can d

I often think about that. There are no guarantees for job safety as an employee, there is only the fact that you work within a statistical ensemble of other people having a very similar job and can use them to tell how well you're doin

That was the first thing I looked at, the angle vs. the movement. It doesn't necessarily have to be something on the camera, it could be internal interreflections. The entire optical system is shielded from the environment by a transpa

That is a very interesting point - would I rather live next to a DuPont chemical plant or a nuclear power plant? I think I would choose the nuclear power plant. Edit: With the nuclear plant I at least have feasible means to monitor any dang

I think that nuclear power generation has been relatively safe over almost a century exactly due to systems engineering, incorporating procedures and the potential for human error. I also think that you are right that some of the systems su

It is interesting that with climate change, the public debate is mostly about 'is it man-made?' as if it'd just become a non-issue if it was. It's debating a fundamental point while we need practical solutions or even ju
