According to Polish typography, opening quote looks like two comas close together and LaTeX correctly translates ",," into opening quote. But this is not two commas. If this mark is not available, it's better to have "Dyrektywy Patentowej" than,,Dyrektywy Patentowej''.
Concerning Rzeczypospolitej or Rzeczpospolitej. Both forms are correct. See PWN dictionary entry. The former is a bit more traditional but they are both OK.
But I don't mind changing to Rzeczypospolitej.

The depth of field depends upon the aperture of the iris
This is true but
depth of field depends also on the focal length and magnification (which is related to the sensor size). The large magnification means that the lens "circle of confusion" should be smaller.
Try any "depth of field calculator", e.g. here
and you will see that on Canon A75 at 16.2 mm telephoto (which has the same filed of view as 105mm 35mm lens) the total depth of field for an object 3m apart at f/5.6 is 2.15m
In contrast for Canon 1Ds with 105mm lens and f/5.6 depth of field is only
0.27m
Of course on 1Ds you can stop the lens to f/22 and and have the same photo with large depth of field (and because of the small noice of the sensor, you can increase the ISO speed without much degradation of the quality and have reasonable shutter speed). With DSLR you have a choice of large and shallow depth of field. With most point-and-shots you have only large.
If you want to have flexibility of interchangable lenses with excellent quick autofocus, total control over the camera, possibility of using external flash, studio strobes, you are serious about your photographic hobby and are willing to pay more for the camera and lenses (sometimes a lot more) and have heavier but more sturdy equipment, buy DSLR.
Otherwise buy point-and-shot.
P.S There are some advanced "prosumer" point-and-shots which are more DSLR-like in some aspects.
"F puts 0 and 100 at the edges of the extreme temperature ranges experienced in my country"
In Celsius it is about -20 to 40. In any system you can get your subjective calibration. Mine is: -20 C ultra cold -10 C very cold 0 C freezing 5 C cold 10 C coldish 15 C cool 20 C warmish/coolish 25 C warm 30 C hot 35 C very hot 40 C ultra hot
There is no need to have it calibrated from 0 to 100. Celsius scale is definitely arbitrary but it is based on properies of water. And water is, well, important for us.
With description of the optics and details of the resultion measurements is here. He created also his own chart which includes shades of grey for better measurements of MTF50.
Call me a nitpick but without reaching escape velocity it is hardly space travel. There may be fun (and profit) but it is not going to be a step toward an affordable real space travel.
still contains Uranium and Plutonium which has a half life of 10^8 years
Minor correction. The isotope with longest half-life is 244Pu and its half life is 80.8 10^6 years. There is very little of Pu244 in nuclear waste.
Fortunately, there is a direct link between half life and activity of a radioactive material. Uranium is so little radioactive that you can safely hold it in your hand. After 200k years this radioactive waste would be only slightly more radioactive than background. After this time you can literally keep it in your backyard.
The changes that were made in the experiment were minor. They will eventually be corrected but how many people know and care at which junction lies Phillipsburg, PA?
Does the person get instantaneously transmitted to the other side or not?
No. You always need a classical channel (with speed of light limitation) to complete the teleportation. You need to know the measurement at location A to cast the state of entangled qubits at state B. Actually, "teleporting" classical information is easier. You copy the data and send it. With quantum states it is harder because you cannot copy the quantum state (no cloning theorem). You need to entangle qubits, distribute them, and send classical data. The whole process is at most as fast as the speed of light. A picture on this page is an excellent nonmathematical explanation of teleportation.
However the reliability of a given RAID-0 set is equal to the average reliability of each disk divided by the number of disks in the set. That is, reliability (MTBF) decreases linearly with the number of members - so a set of two disks is half as reliable as a single disk
If P is the probability of the drive failure during certain time, then if the failure rate is independent on all the drives, then (1-P)^n is the probability that all of them survive (which is necessary for RAID-0 consistency). If you have 4 drives and each has 20% failure rate, then you have 1-0.9^4=59% probablility of a failure of the whole array.
The intro is not accurate. Actually, they are detecting regularities in the forged pictures.
I've looked at their scientific
paper and their technique albeit not perfect seems to be very good in detecting any kind of resampling in the image (up- and down scaling, rotating, etc.). When you make the transformation on a grid, the interpolation creates some almost invisible artifacts and regular patters which they are able to find by their analysis. It's difficult to create forgieries without these kinds of manipulation. But probably not impossible.
Actually, we don't understand all the fundamental theories. That's why there is a dream to find a "Theory of Everything". But unless the present model is inaccurate or cannot explain some phenomena, the meta-theory doesn't change anything and there will always be questions how this meta-theory works. But this question belongs to philosophy, not to the science.
The simple answer for "how or why the quantum theory works?" is "We don't know and we may never know but we have some equations that can predict the experiments with incredible accuracy".
178g of hafnium 178 is 6.02E+23 atoms (Avogadro constant). 6.02E+23 x 2.5 MeV = 1.5E+30 MeV = 2.41 × 10E+11 J = lighting 100W bulb for 76 years.
Natural hafnium contains 27% Hf-178.
This Hf-178-m2 is radioactive and requires roughly the same protection as radioactive cesium-137 but it has an excited nucleus and there are no decay products apart from normal stable Hf-178. Getting it excited is not a cheap process, though.
There is a conspiracy theory that NSA knows some (secret) cryptoanalysis methods and can break the public encryption algorithms faster than by a brute force attack.
that the chargers for this kind of batteries would be enormous. 1000mAh charged with 100% efficiency for 30s requires 120A. This is like starting a car engine. No reasonably portable charger can provide this current.
I did some teaching of command line for non-English-speaking students and the biggest obstacle was the language barrier. They couldn't remember the command and they didn't understand the output of the command. Even if they knew some English, there were always some technical terms they couldn't understand and they felt intimidated. This way they were much more efficient in a localized GUI.
Does anybody expect privacy in public places? You can be watched and photographed by anybody legally in public. Does this surveillance cameras change anything?
I certainly don't see myself "winning" anything by the collapse of the USSR, with it's 0% unemployment rate and lack of poverty.
You are lucky that you have never lived in a communist country. I live in a former Soviet "satelite" country which was not so poor but there was poverty during communist times. It may have been not so bad as in third world countries (people generally had something to eat and a place to live) but nevertheless quite a lot of people had miserable lives in Western standards. There were shortage of many basic products, many people lived in crappy homes (small rooms or only one room for the whole family, sometimes no hot water, no toilet, etc.) but the Party bonzos were affluent. There was strong corruption and there were people equal and "more equal". There were some areas that worked OK (I think the education was not that bad) but in general it was bad.
And did I mention freedom?
It may not be great now several years after collapse of the regime and not everything is perfect now (being unemployed is not funny), and there is a lot of room for improvement but most of the people are better now.
These are nice experiments but definitly not
"a scientific breakthrough in providing a new type of quantum mechanical behavior".
Yes, fermions (particle with spin which is an odd multiple of 1/2) are different beasts than bosons (with integer spin) and fermions cannot form Bose-Einstein condensate but fermions can form pairs
that are bosonic.
It has been observed in many cases. Superfluid He-3 (which is fermionic) requires fermion pairing and it has been observed quite long ago (and given 1996 Nobel Prize in physics). So getting Bose-Einstein condensate from rubidium atoms is interesting research but this is not a breakthrough and not a "sixth state of matter". This is still Bose-Einstein condensate but made not from atoms but pairs of atoms.
When an economy is going through deflation, it always makes more sense to spend as little money as possible, since prices will be lower in the future.
It is much more complicated. Deflation is a symptom of illness, not the cause (the illness is bad productivity). There are hundreds of deflating markets that thrive. Why buy this shiny new [insert any high-tech gadget] when better and cheaper will be in just a few months? But despite that most of these soon-to-be-obsolete gadgets sell like hot cakes.
It took dictators and tyrants (Lenin; Hitler; the original French savages) to force people to switch to the inferior (in practise; on paper, of course, French units appear far superior) units.
Nice troll but Germany made metric as compulsory in 1868
and both Germany and Russia
signed the Metre Convention in 1875 long before Lenin and Hitler.
Well, our numerical system is based on 10 as a base. It make more sense to have the same base in units.
If you think there is nothing to remember, tell me without looking to google, how many gallons are in one cubic foot?
