No, numbers are not imaginary. Digits and numerals, which are the way we represent numbers, are imaginary. The numbers themselves are not.
What's a number, then? Can you point to a number in the real world? Where is 2? Where is 4? If you put two apples on a table and say, "There, there is two.", then where is the two? The idea of two separate apples is itself a mental construction: imaginary.
I agree. This is why I have a hard time with math as a concept, I need to be able to learn how something works, why it works, the history of it etc, numbers are simply a construct we came up with as a means to measure the world and communicate, I can't feel or touch a number, it's all in your head.
Wasn't able to load the article, but I'd describe God in one word as 'known'. I chose this word, because many people know about God. It must be most of the world, yeah? Everyone has a different perception of him, thus there being so many different religions and sorts. But no matter what they think of this guy, he is known by so many.
