As absurd as these visualizations are, it does raise the bigger point that it is very difficult for our brains to understand large numbers.

It is difficult for most people to really grasp how much 184 million gallons is, or to tell the difference between $1 Trillion in bailout vs $2 trillion in bailout money. After some point, we just give up and call it "a lot". I think this has very real public policy consequences.

But I'd bet, we'd very much understand if your boss said he was cutting your $100k salary to $50k.
