Do atheists need some faith?

Why do you continually use examples of what is understood to compare to reality.

Because reality, like those examples, is also understood.

It must be safe to assume that you believe you understand reality as well as numbers.

Nope, I understand the numbers better.

This leads me to go back to where this began. You claimed that it's non-nonsensical to ask how big reality is. I make no claims to understand what reality is, I know how I perceive it but am wise enough to make a distinction between my perception and to make claims about what questions I can answer with certainty about whether its nonsensical or not.

Accepting limits imposed by your stupidity is wise.

What makes you think you can? If the material is all that exists then why do you propose reality cannot be measured?

As I have explained many times already - for anything to be measured, we require a standard of measurement that exists independently form the object being measured. Since all such standards would automatically be a part of reality - measuring it is nonsensical.
