I appreciate the positivity of your message, but I would be more cautious in giving advice to strangers on forums. How can one know that the poster is going 100% in the right direction without knowing more specifics than what is written in

I would just like to point out to dba7dba that his account seems to be banned and the post appears as [dead], just like all the other posts he wrote in the past 294 days (but not those before). Reading his contribution in this thread and so

I'm not sure about this particular paper, but in most theoretical fields the authors are listed alphabetically by last name (the assumption being that each of them made a contribution without which the paper wouldn't exist - so ra

Off-topic, but just wanted to add that the four comments above exemplify why I still find hope in HN discussions. Each one adds some new insight, refining what was said previously and does it in a constructive way.

There is also a follow-up "The Two Cultures of Mathematics" by Timothy Gowers. I found it a crystal clear explanation of the differences between the schools of "problem solving" and "theory building" - and part

I'm trying to understand the argument you are making, but it seems logically correct only if the previous comment were "underestimate" instead of "overestimate".

Roger Penrose has famously speculated on the connection between quantum physics and consciousness in his book "The emperor's new mind" and follow-ups, but as far as I know, the idea is not very highly regarded in the scientif

I wonder what would happen if thousands would coordinate to post similar jokes, thereby swamping the legal system and pointing out the absurdity - similarly to the http://en.wikipedia.org/wiki/AACS_encryption_key_contro

I don't think he meant that EE is just a matter of math, but rather that branching out into EE can be thought of as analogous to branching out into math.

You seem to have an axe to grind - almost all the points you mention (assuming they are true) can describe a well managed company, if you skip the negative spin.

In that case, I apologize - I possibly misread "do agree" as "disagree" the first time, based on which I had a mental image of what the post said, and on a second, more careful reading it seemed changed.

I haven't read the article or much of the discussion here, I would just like to point out that you are applying (maybe unintentionally) a fallacy called "excluded middle", frequently used in propaganda of all sorts. Between being an absolut

I'm not feeling bad, in fact, it seems that I had two more weeks of getting used to than you, looking at when our accounts were created, :) The post to which I replied has been edited. Where it now says "I do agree" it used to say "However,

Are you sure you are arguing with the parent post? I think he's expressing a pro-nuclear sentiment similar to yours.

I think your condescension is unnecessary, you know nothing about my reading (or Googling) habits. By any reasonable definition, Ukraine is in Eastern Europe, whether you use geographical, political or historical definitions. This is what W

Why does it make it less interesting? Overall they achieve more overhang for the same number of bricks than the other construction, n^(1/3) instead of log(n).

Big-O is just a formal notation for comparing growth rates of functions. You are right of course, that often one might get away without the precise formalism and rely only on a gut feeling - but there are limitations on how many things we c

Yes, I didn't mean to sound pedantic - just meant that there is no single way to measure time complexity of algorithms - when we talk about sorting, often we assume the comparison model: only comparisons between elements count, and we can't

by lkozma 13y ago
Your first paragraph is also a slight misunderstanding of big O notation. In fact, the notation allows to make general comparisons between the growth rates of arbitrary functions, not necessarily referring to time complexities of algorithms

I find both the questions and answers confusing, I think this is a case when a little more "formal" understanding would help before jumping into "intuition" and big picture explanations. If the question is really what O(log n) means, then t

What you say is obviously true, but there must be some curve between the effort needed to make it useful and the utility derived from it, based on which some people can rationally decide that it is not worth it for them, while others can de
