Sure, but verroq was talking about vector spaces and linear maps, not matrices. The theory of vector spaces over a field is more general and can be applied to much more than systems of equations.

Whether or not someone is sufficiently motivated to study something should not affect their ability to understand it. Vector spaces and linear maps are actually much easier to understand, and I think that at some point in mathematics (probably your first analysis course) your motivation has to come from the beauty of the theory itself rather than some real-world application.

As is often the case, the way to get the intuition here is to just work out the computation. Once you do that, it should all "click".

What in Clojure is biased towards web programming (or any other domain)?

No, that means on average, an arbitrary set of eight adults contains two with a mental disorder. (Presumably this refers to adults in the U.S.)

If you believe this, then what is the purpose of putting illegal drug users in jail?

Mostly, when I come across complex equations in CS papers, I tend to skip over them and only go back to look at them if there are parts of the paper I can't make sense of without them - it is very rare to find that they are necessary at all.
Obviously any equation can be expressed in words, but those who are familiar with the notation are able to read the equations and understand the ideas in a paper in a fraction of the time. This is important for those who read papers regularly.

Dear kristianc,
You are comparing en.wikipedia.org with their redesign of www.wikipedia.org. Notice that the latter is, with respect to content, the same as their redesign: languages, search, and sister sites.
Secondly, in the screenshot you are looking at, the content of the article has obviously pushed down due to the activation of the “quote” mode. Honestly, I doubt you do not realize this and I can’t help but wonder what motivation you have to criticize their work so unfairly.

The funny thing is that most of these APIs wind up with what's essentially a "this" pointer at the front of every argument list so you're really doing OO anyway.
Do you have much experience with non-OO programming? Or even OOP, for that matter? How can one honestly believe that every instance of passing data into functions is automatically OOP? Did you even consider the fact that this has nothing to do with objects?
Time objects are a really bad example because time calculations are exactly the kind of hairy mess you want to hide behind some kind of abstract API.
You miss his point here. Time not being an object would not imply that it can't be abstracted into an API. Just see Clojure's clj-time library for an example.

I don’t see an interpretation that makes sense. In fact, I don’t think there is one. I guess you define a “statement” to be a complete sentence, judging by “its title alone isn’t a proper statement”, but titles are rarely statements anyway and the actual contents of the novel, I am sure, are full sentences. We need to use more precise language, instead of hiding behind vague terms like “statements”, if we hope to evaluate the argument.
I am not nitpicking. I honestly don’t think any sense can be made from leot’s statement. If I am wrong, I invite you to refine it in a way that makes sense. Your earlier refinement (text is not the best medium for every message) makes sense, but the point is that art is not defined as “mediums other than text”, and therefore it isn’t relevant to the previous discussion about art.

This is a more precise statement, but you have replaced “art” with “other mediums than text”. Is literature not art?
adeelk | 13 years ago
This statement is meaningless as is and I think if you were to make it precise you would find it ridiculous.

Not sure I understand your point. Gauss is credited for the term “complex number” as well.
