I think your observations are correct. There are some differences between the U.S. and Europe that may explain it: i) the U.S. is protected by two vast oceans, and Canada and Mexico were never a threat. By contrast, Europe has been under si

"It also helps me understand some of the frustration European Muslim immigrants must feel, being pressured to give up their own heritage, culture, and beliefs or be ostracized." Oh, come on. Do you think that Muslims moving to the U.S. do

Citizens and guests are not the same thing. You're reading the word "guest" too literally. In Europe, anyone from a different culture is a "guest" until proven otherwise. You may be a citizen, vote, pay your taxes... but until you have been

"What's wrong with them preaching that their values are better?" Suppose that you invite people to your house. Rules of etiquette say that the guests should not tell you how to live your life. Nobody likes to be told what to do, nor how t

Sure. I was being facetious. 1000s of humans die everyday of preventable disease. There are greater tragedies on my book than 3,000 wild rabbits in a crematorium...

But were the rabbits dead? Or were they killed? There's a difference between bunny-recycling and bunny-mass-murder :-D

Danish people tend to be confrontational. At least that's the impression I got when I lived there. Such a cartoon could only come from Denmark. It's offensive and distasteful, and the author should have kept in mind that insulting 1 billion

In 2008, Physics Nobel laureate David Gross gave a talk at Technion [1] and mentioned that this belief that Jews are smarter is dangerous, as it may give Israelis the impression that its accomplishments are God-given, and not due to hard wo

My comment on efficient markets was facetious. Sure, one must consider the time spent at the flea market, but what numerical value does one assign to 1 hour of one's time? In the end, I find that the question "are markets efficient?" is not

Note that: "is" and "is represented by" are not the same on my book (which is obvious from the previous comments). If you want to counter-argument, try harder.

Not quite. One can encode anything into a number. Decoding is what it's hard, especially so if one does not know what the encoding scheme was. I suppose this is one of the reasons why NSA needs astronomical amounts of computational power.

For an image to be a number, I demand a one-to-one correspondence between images and numbers. Lacking that, I merely say that an image can be represented by a number, but this is trivial. Hence, I repeat: we're not even discussing the s

To make things even more fun: Take an image x , decimate it, and obtain a lower-resolution version of it, which we call z . Are x and z the same image? Mathematically, no. But when displayed on the screen, then most people would say t

I asked: "How can an image be a number?" , when I should have asked instead: "How can a number be an image?" To use the verb to be in this scenario, I demand a one-to-one correspondence between numbers and images. If a number y can repre

Indeed. It seems that for most people here is means can be , while I demand a bit more. Yes, in practice, f will be one of a few mappings, but that does not change the fact that knowledge of f is required. In practice, one merely tri

I am pointing at the forest, and you're looking at the trees. We're not even talking about the same thing. I am taking a very high-level, abstract view of the problem. You're thinking of implementation.

Wow. Someone got extremely lucky, then. I know people who would prowl flea markets and antique stores, and sometimes they would find some seriously under-valued assets. And the academics say that the markets are efficient...

I would not trust YouTube comments all that much. Buying a Curta for 13 cents would be the arbitrage opportunity of the decade. You could sell it on eBay for more than $1000 (there's no shortage of collectors looking for Curtas, myself incl

Thanks for wording it more precisely than I did. Most people are assuming that the mapping tuple -> number is known, while I am not. I could come up with my own invertible mapping. The cool thing would be this: - I carry a large number

Geees, is this HN??? Am I the one who's too stupid to explain things properly, or is everyone under the weather because it's Monday morning? An image is a 2-dimensional array. Say it's a M x N array. Suppose we use RGB so that each pixel

That's not what I meant at all . Of course you can transform a list of bytes into a number. But can you transform a number into a list of bytes? That is the problem. If you know the "encoding" algorithm, then you can. If you do not, then y

OK, Mr. "Ramanujan", let's play a game: I give you a binary string, and you tell me what image corresponds to it. Are you game? I won't tell you how the bitstring was computed from the image. I don't tell you how many pixels the image has.

by Rod 17y ago
Technically, a string of digits is only a representation of a number. And such representation may not even be unique.

You are totally missing the point. The 3-tuple (1,2,9) may represent number 129 if you use the decimal expansion. What if you use a base-16 expansion, or a base-8 expansion? You can even choose the base so that the tuple -> number map

How can an image be a number? This is an honest question. Isn't an image a list of numbers? These numbers could the RGB of each pixel, or the N higher Fourier coefficients, etc. From these numbers, one can compute a single number, sure. Non
