I almost changed the title of this item to "Degrees in English", but that
would be a bad pun.
Before coming to Israel I worked at an insurance company very near a tall
building whose top floor was a rotating restaurant. You can see a picture
of it here:
http://www.metrojacksonville.com/article/2008-nov-the-universal-marion-building
As explained in that website, the restaurant rotated 360 degrees every 90
minutes. That's 4 degrees per minute.
By contrast, the earth rotates about 1 degree every 4 minutes, or 15 deg
per hour, 360 deg per day.
The moon arrives about 53 minutes later every day. In other words, wherever
you see the moon today, it will be at that spot in the sky about 53 minutes
later tomorrow.
The moon arrives later each day because it revolves around the earth in the
same direction that the earth rotates. So after the earth has rotated a
full circle, the moon has "advanced" a little.
The moon takes about 28.25 days to circle the earth. While we make 1
rotation, the moon advances about 360 / 28.25 days = 12.75 degrees.
By the time we spin 12.75 degrees, the moon has advanced almost another 1/2
degree, so we need to spin an extra 13.25 degrees to see the moon at the
same angle we saw it yesterday. We spin 1 degree every 4 minutes. So, it
takes us 4 * 13.25 = 53 minutes extra to see the moon where it was
yesterday.
Because the moon's orbit is an ellipse and not a circle, it travels faster
when it is closer and slower when it is farther away. Therefore, it
actually takes between 51 and 55 minutes extra, but on most days, the delay
is very close to 53 minutes.
To see 6 English cognates of yod-resh-het (moon), view the yellow
highlighted paragraph in this file in my public DropBox

Finally, the reason the moon the moon is made of green cheese is because
the Hebrew pat phrase YaRei'akH GaVNooNi (gibbous moon) sounds like YaRoK
G'ViNa (green + cheese).

My advanced English class has set up a site where I can contact them.
Not only do I send homework, answer keys, essay corrections that way,
but I want to enrich their knowledge IN ENGLISH so I send them information,
like the site below, where they can HEAR English spoken and learn something
new.
