A Day in the Life of a (mostly) Human Sundial.

“Als Schulprojekt der Astronomie-AG des Progymnasiums Rosenfeld haben wir für einen Schultag eine lebende Sonnenuhr realisiert. Jeder sollte für 10 min Gnomon einer Sonnenuhr sein. Alle 20 s wurde ein Foto aufgenommen und somit der Tag von 8 bis 16 Uhr zugebracht. […] Man achte im Video auch auf die Turmuhr zum Vergleich (alles MESZ).”


“The astronomy club of the secondary school in Rosenfeld (Germany) made a living sundial for one day. Everyone was the gnomon for 10 minutes. A photo was taken every 20 seconds throughout the day from 8am to 4pm. […] Note the time on the clock tower for reference (all times CEST).”

Peers pose a large threat

Deutsche Welle: Study shows German students frequently exposed to sexualized violence. “A German study has found that 48 percent of surveyed students aged 14 to 17 have experienced verbal or physical sexual violence. Researchers said that the violence was often carried out by the students’ peers.”

“When presenting the results on Thursday in the city of Wiesbaden, the study’s two main researchers highlighted one of the study’s main takeaways – that fellow students are often the perpetrators.

“The main risk for [perpetuating] sexualized violence are other youths – meaning their peers,” Professors Sabine Maschke and Ludwig Stecher said.

Around 48 percent of the perpetrators of physical sexual violence and 64 percent of those who carried out non-physical violence were “friends” or “classmates” according to the study.

Additionally, students reported that over 50 percent of non-physical sexualized violence occurs at school.”

Three YouTubers on a zero-g flight:

Physics Girl: Zero G Ferrofluid Fail. (10:48min)

Veritasium: Fire in ZERO-G!! (7:47min)

e-penser: Vol en zéro-G. (35:26min) This one is in French, but English subtitles are available.

This looks like so much fun! I would accept an invitation in a heartbeat, since tickets usually cost several thousands of dollars…
