Sizing Things Up....

The purpose of this blog is to macro-manage the Shabbat table conversation... Please print and share...
Here's your countdown to Shavuot

Do you remember last week's teenager's dream that became a reality?

As you can see, we indeed inaugurated it this week on 
Lag B'Omer.

It's small for a bonfire, but sometimes smaller is more impactful.

Let's put this in the form of corona trivia questions for your Shabbat table:

1. How big (or should I say small) is this virus? What's the actual size? [roughly 100 nanometers]
2. What does "nano" mean? [billionth — 1/1,000,000,000]
(not to be confused with "micro" which means millionth)
3. How do you write that in decimal? [
0.000000001]
4. How big is that in millimeters? [one one-millionth — 1/1,000,000]
5. How do you write that in decimal? [
0.000001
]
(Bonus question - why does the fraction version have one more zero than the decimal?)
7. So how big is the virus in millimeters? [1 ten-thousandth of a mm]
8. How many could you fit on the tip of an average human hair? [about 30,000] (as far as I can tell, I'm a bit rusty at packing problems)
9. How does that compare to bacteria? [a lot smaller!]


10. Final Q for your table: Is there a deeper lesson to the fact that such a tiny thing could up-end the entire world?


Shabbat Shalom
