As humans kept wandering, they fertilized places along the way—especially those “rest stops” where their clans chose to stay for a while. Some of these early humans may have even noticed that plants tended to grow bigger, better, and tastier in such rest stops. So, tribes made a point of coming back to those spots the next season, or even several years in a row—and then, one year some decided to just settle at those convenient spots. These early settlers brought us to the advent of farming.
For example, the Fairbanks International Airport in Alaska renamed runway 1L-19R to 2L-20R in 2009 when magnetic north shifted enough to mandate a change. And the airport operators know—from NCEI’s World Magnetic Model (WMM) and other sources—that they’ll likely need to update the name again in 2033…
“Many of us want more renewable energy, but where do you put all of those panels? As solar installations grow, they tend to be out on the edges of cities, and this is historically where we have already been growing our food,”
“We started to ask, ‘Why not do both in the same place?’ And we have been growing crops like tomatoes, peppers, chard, kale, and herbs in the shade of solar panels ever since.”
Magnetic stripes (magstripes) are in fact magnetic. What’s so cool about magstripes is that while the magnetic strips inside are weak, they’re still strong enough to attract small ferrous particles and wide enough that we can fully extract all data from a magstripe or credit card with the naked eye.
Eclipses recur over the Saros cycle, a period of approximately 18 years 11 days.
The saros is a period of exactly 223 synodic months, approximately 6585.3211 days, or 18 years, 10, 11, or 12 days (depending on the number of leap years), and 8 hours, that can be used to predict eclipses of the Sun and Moon.
Though Huntington died in 1927, he intended his collection to live on long after him, but as the librarians discovered, the volumes were literally too full of life. The problem with assembling a massive collection of books is that you necessarily collect the very organisms that feed on books.
