"Maybe if I had cared less about language I would have accomplished more in
physics.
Phenomena is plural.
Phenomenon is singular."
Actually I did care, and still care, quite a lot about language. However, I
make no claims about how much I have accomplished in physics. There are
several things of interest in the video that I have not seen before. One is
simply the complete rising of a full moon (I grew up, and remain, in a
city/suburb environment). Another is the silhouetting effect of a full moon
rise. A third is the contrast between the angular rate of a person walking
across my line of sight compared with the angular rate of the moon's rising.
I believe my use of the word "phenomena" was correct given my particular set
of life experiences.
