One more day until the US election

Quartz.com: America is more fragile than you think: A former Marine Corps officer on why voters must defeat Donald Trump.

“When I came back from Iraq the second time, I had trouble driving. My tours as a Marine had shown me how easily metal could tear through flesh. Now I was acutely aware that life is precarious. I was amazed that people could be blasé while driving 80 mph. Could they not see that a small mistake could be enough to kill them?

I feel the same way now as an American citizen, watching a good portion of the country consider voting for Donald Trump. Having grown up in the Midwest and served in the military, I can understand why both have large constituencies supporting the Republican presidential candidate. But I believe Trump supporters underestimate how fragile what we have is.”

Dancing water droplets in an air bubble inside a water bubble in space

Smarter Every Day 160: The WALKING WATER Mystery (in SPACE and SLOW MOTION!). (YouTube, 12min)

Destin Sandlin explains why you often see water droplets dance or bounce on the surface of water instead of coalescence occurs.

This video features astronaut Don Pettit, who did a cool experiment in space: He attached a big water bubble to a speaker, then inserted an air bubble into it. When he played cello music (by Yo-Yo Ma) through the speaker, little water droplets would detach from the water and bounce around inside the air bubble. You can see it in the above video starting right here.

Ernstzunehmen

Kinderdoc: Wenn der Kopf brummt.

“Kopfweh kommen in allen Altersklassen vor, vermutlich auch schon bei Säuglingen. Jedenfalls werden klassische Symptome wie Sehstörungen, Sprachproblemen und eben dem typischen frontalen oder haubenartigen Schmerz des Kopfes bei anderthalb- oder zweijährigen beschrieben oder auffällig.”

Interessant für selbst Betroffene oder Menschen, die mit Kindern und Jugendlichen arbeiten.
