We began this blog five years ago, in July 2010 (HERE is the initial plan we laid out). Over the last five years, we have never missed a Wednesday post, and we’ve often posted beyond the regular Wednesday edition.
To celebrate this five-year mark for Lofty Ambitions and to shake things up a bit here, we’ve decided to post lists of five things, at least for a while (maybe five months). We’ll stick to our topical focuses: aviation and spaceflight, science of the 20th century and beyond, and writing as a couple. And we’ll continue to think broadly about those areas of interest. The lists of five are a different way to think about form and to look at topics anew. We have some ideas already, and we expect that we’ll come up with more ideas along the way.
So, to start this new tack, here are 5 things about 5:
- Five is divisible only by itself and 1; hence, it is a prime number.
- Five is the only prime number to end in 5 because, of course, other numbers that end in 5 are also divisible by 5.
- The Roman numeral for 5 is V, as in the Saturn V rocket.
- A polygon with 5 sides is called a pentagon, and a starfish exhibits appendage pentamerism. Pent- is the Greek prefix for five.
- Five is the atomic number for the element boron. Boron is not found naturally on Earth in its elemental form but is sometimes present in meteoroids.
Bonus: On the scales for measuring tornadoes and hurricanes, 5 is the highest or most powerful.
And don’t even get us started with popular culture references!
