I am looking for the best visual description of what one billion is. Here are some examples: A billion is a difficult number to comprehend, but one advertising agency did a good job of putting that figure into perspective in one of its releases. a.. A billion seconds ago it was 1959. b.. A billion minutes ago Jesus was alive. c.. A billion hours ago our ancestors were living in the StoneAge. d.. A billion days ago no-one walked on two feet on earth. e.. A billion dollars ago was only 8 hours and 20 minutes, at the rate our government spends it. Too abstract. I need something tangible. The most recent example I have heard, and one I can almost grasp is the following: Take a wheat seed, and imagine it filling up all the rooms on the first floor of your house. That would be one billion wheat seeds. I have no idea how big a wheat seed is. Here's a couple more: The length of your thumb is 1,000, your thumb to your elbow is 1,000,000 and your elbow to the equator (from where ever you are currently reading this from...I hope it's no where near the equator) is 1,000,000,000. A dump truck full of sand has 1,000,000,000 grains of sand. So, here is my request: what is the best visual representation you have ever heard in attempting to grasp what 1,000,000,000 is? Thanks!
