Beams of light

My daughter worked on a farm for a few years. Now she is working for the county, helping people learn to farm and to produce food for community uses. The program's students visit working farms, as part of what they do, so they can see what works well in this area, and ask questions. They help out, while they're there.

When Holly sent this photo, she called it "God's Tractor." I suppose it was on one of the farms they visited. Sunbeams. "Beam" is an interesting word—"light beams." Wood beams—those are just heavy, solid things. The wood doesn't beam down on us; that would be dangerous. Both uses of "beam" are very old, though.

The "beam" terms used by gymnasts and by aviators are newer. Holly's paternal grandfather was a Navy pilot in the Pacific during WWII, doing reconnaissance flights. He was a flight instructor, but he told us that unofficially, in Hawaii they used a local radio station to return to base, rather than the prescribed military method. That's one meaning of "on the beam"—to follow a beaming radio signal toward its source.

Seeing sunbeams shining right down on something could easily be part of the reason for sun-based religions. Coronas and halos are sometimes shown as beams of light, in religious art and in kids' imaginations and drawings.

It's good, when a photo of a tractor in New Mexico can lead to the history of England, and of English; to ancient Egyptian religion (and Mexico's and Peru's...); to medieval and Renaissance art in Europe; to Hawaii, and to women's gymnastics all over the world.

I googled a question. Here:
Are light sabers beams of light?
