For example, a square that is one unit by one unit contains an infinite number of points. A square that is 2x2 also has an infinite number of points. Neither square is infinite, merely the number of points within it. Subtracting the former from the latter still gives us 3 square units.
There are other ways of approaching the problem though. The best known one is the use of certain types of projections that can compress infintely long objects to finite ones. Conformal mapping of this sort is sometimes a helpful way of solving some mathematical problems. It's usually covered in a course on functions of a complex variable. Something similar seems to be the case for hyperbolic maps which M.C. Escher sometimes used to represent infinite objects within circles.

Another possibility is to consider a bounded fractal curve. In a true mathematical fractal, there are infinitely many self-similar scale levels. This (in theory) creates an infinte length/surface that is also bounded.
The scientific method," Thomas Henry Huxley once wrote, "is nothing but the normal working of the human mind." That is to say, when the mind is working; that is to say further, when it is engaged in corrrecting its mistakes. Taking this point of view, we may conclude that science is not physics, biology, or chemistry—is not even a "subject"—but a moral imperative drawn from a larger narrative whose purpose is to give perspective, balance, and humility to learning.
