Astronomy
Earth and moon viewer:
“You can view either a map of the Earth showing the day and night regions at this moment, or view the Earth from the Sun, the Moon, the night side of the Earth […]
In addition to the Earth, you can also view the Moon from the Earth, Sun, night side, above named formations on the lunar surfac. or as a map showing day and night.”
I could waste hours playing with the settings and exploring the possibilities offered on this site. Maybe I should re-think my choice of occupation and become an astronaut after all. (I watched Apollo 13 this week, thrice: First, with the normal soundtrack, then with comments from Jim and Marilyn Lovell, and again with a commentary by the director, Ron Howard.)

School
One more day and two more lessons before the weekend. I’m so ready for that. – Don’t get me wrong, I like my school, the colleagues and the pupils I’ve been teaching so far, but I’m not yet used to getting up so early.
