Hi Wexler,
The list is out of date... a billion seconds is about 31 years 8 months.
Substitute "peppercorn", "match head", "tic tac", or "rice bubble".
That one's just wrong.
For starters, your forearm isn't 1000 times longer than your thumb (unless your forearm is like 150 feet long!), and going 1000 time longer again only takes you 50km away.
That doesn't sound right either. Grains 1mm across would make pretty coarse sand, but a billion grains would take up roughly 1 cubic metre and weigh about 1.5 metric tonnes. That's a big ute load (pick-up truck), not a dump truck.
Your average scoop of beach or desert sand would have much smaller grains. A billion 0.2mm grains would only weigh 15kg, and fit in a big bucket.
Hmm.
Try counting.
Let's say you want to put yourself to sleep, so you count sheep. Say you can count really fast, about 10 sheep every second.
Those sheep are really running past fast!
- In a second, 10 sheep go by
- In a minute, 600 sheep go by
- In an hour, 36000 sheep go by
- All night (12 hours - you have bad insomnia), over 430,000 sheep go by
- In a week (24x7), 6 million sheep go by (You should really see a doctor about this problem)
- In a month, 25 million sheep go by
- After a year, you've seen over 300 million sheep. That's a year of your life you'll never get back!
- Keep going... if your concentration and sanity hold, you can count a billion sheep in only 3 years and 3 months. Hooray!
Or maybe money. Try the
Megapenny project:
Visualizing huge numbers can be very difficult. People regularly talk about millions of miles, billions of bytes, or trillions of dollars, yet it's still hard to grasp just how much a "billion" really is. The MegaPenny Project aims to help by taking one small everyday item, the U.S. penny, and building on that to answer the question: "What would a billion (or a trillion) pennies look like?"
Here is a picture of one billion pennies from that site:
