A choice is the range of different things from which you can choose. The arrival at a choice may incorporate motivators and models. For example, a traveler might choose a route for a journey based on the preference of arriving at a given destination at a specified time. The preferred (and therefore chosen) route can then account for information such as the length of each of the possible routes, the amount of fuel in the vehicle, traffic conditions, etc.
Simple choices might include what to eat for dinner or what to wear on a Saturday morning – choices that have relatively low-impact on the chooser's life overall. More complex choices might involve (for example) what candidate to vote for in an election, what profession to pursue, a life partner, etc. – choices based on multiple influences and having larger ramifications.
Freedom of choice is generally cherished, whereas a severely limited or artificially restricted choice can lead to discomfort with choosing, and possibly an unsatisfactory outcome. In contrast, a choice with excessively numerous options may lead to confusion, reduced satisfaction, regret of the alternatives not taken, and indifference in an unstructured existence;
and the illusion that choosing an object or a course, necessarily leads to the control of that object or course, can cause psychological problems.
Which of these 3rd quarter 2008 papers do you predict will prove most valuable to future research? Significant papers tend to be cited more in subsequent research---we will soon have citation counts to go by, on some of these, as well as subjective judgment. Polling let's us share information as...
Does there exist a theorem, whose proof relies on the axiom of choice, and which has practical or concrete applications? I'll consider for example PDE and number theory problems practical or concrete, because they can be intuitively connected with the physical world. On the other hand, for...

Consider the line element:
ds^2=-f(x)dt^2+g(x)dx^2

g(x)dx^2=dy^2
and then calculate everything in the (t,y) coordinate system. My...

It seems strange to me that in such a simple case as the following the equation of motion depends on the choice of metric! In flat space we have say:

Suppose \phi depends on space alone and we work in 1+1 dimension. then

Feel free to give your reasons.
I voted yes, because too many useful theorems are thrown out the window if Axiom of Choice is rejected. I believe that these useful theorems outweigh the surprising (strange?) results that also arise from AC (e.g. every set can be well-ordered). Also, if AC...
I, by the first time, came across with the Axiom of Choice today, found it beautiful, of course.

For example, do...
