## nt.number theory – Is there a difference between using nats and bits to express entropy?

It seems to me like questions involving decimal vs binary representations of some number are not particularly interesting: for instance $pi$ or $sqrt{2}$ are conjectured to be normal in every base, and as far as I know this is open for any particular base.

On the other hand, in calculating entropy there is again a choice of basis. Further, this gives us certain ‘distinguished’ real numbers: e.g. the entropy of the Gauss-Kuzmin distribution is $3.432527514776…$ bits, while it is $2.379246769061…$ nats.

Are the properties of these digit strings of the same number ‘similar’ in any way, or is one ‘nicer’ in some sense?

## If sensor resolution numbers increase significantly from 12.1 MP to 50.6 MP, why’s actual difference in horizontal width much less pronounced?

I don’t understand the embolded phrase below from Camera Resolution Explained. Please explain like I’m 10. I’m unschooled at photography or physics.

How’s “the actual difference in horizontal width” “much less pronounced”? I don’t understand what that first collage below (showing 12.1 MP to 50.6 MP) is trying to prove?

In order to yield twice larger prints at the same PPI, you would need to multiply sensor resolution by 4. For example, if you own a D700 and you are wondering what kind of sensor resolution you would need to print 2x larger, you multiply 12.1 MP (sensor resolution) x 4, which translates to a 48.4 MP sensor. So if you were to move up to say the latest Canon 5DS DSLR that has a 50.6 MP sensor, you would get prints a bit larger than 2x in comparison. To understand these differences in resolution, it is best to take a look at the below comparison of different popular sensor resolutions of modern digital cameras from 12.1 MP to 50.6 MP:

As you can see, despite the fact that sensor resolution numbers increase significantly when going from something like 12.1 MP to 50.6 MP,

the actual difference in horizontal width is much less pronounced. But if you were to look at the total area differences, then the differences are indeed significant – you could take 4 prints from the D700, stack them together and still be short when compared to a 50.6 MP image, as shown below:Keep all this in mind when comparing cameras and thinking about differences in resolution.

## What is the difference between $SIZE(n^k)$ and $P/poly$?

$SIZE(n^k)$ is defined as the class of problems solvable with Boolean circuits (of fan-in two) with $O(n^k)$ gates. While $P/poly$ is defined as those problems over **{0,1}*** which can be solved by an infinite family of polynomial-size circuits ${Cn}$.

## Difference between impersonation and masquerading attacks

According to a book that I am reading, an impersonation attack is a more active attack than masquerading but I thought they are the same thing. How is this so.
