Re: Nonsense.
"I could just hold and see it all at once in my head."
I find the same thing - the ability to more or less visualise things which are intrinsically invisible. I think it's a form of synesthesia. There were a number of instances where Feynman gave examples of what seems to have been synesthesia such as seeing equations in colour. I suspect talent in any direction is at least greatly aided by an individual ability to adapt mental functionality from one specific area to another.
A further example might be the ability to memorise large numbers of facts. Those who can do it explain it in terms of imagining a story or a journey which prompts the facts. If I try to do that it simply becomes an extra layer of difficulty, not an aid.
