Live from the International Space Station ISS

ESA: Good evening, Kraftwerk / Guten Abend Kraftwerk, guten Abend Stuttgart! (YouTube, 11:48min)

“On 20 July 2018 around 21:50 local time, ESA astronaut Alexander Gerst welcomed the legendary electronic band Kraftwerk and 7500 visitors to the Jazz Open Festival on Stuttgart’s Schlossplatz – live from the International Space Station, where he will live and work until mid-December 2018. During the call with space, Kraftwerk founding member Ralf Hütter and Alexander played a special duet version of the track Spacelab, for which Alexander had a tablet computer configured with virtual synthesizers on board.”

Alexander Gerst’s Horizon Blog: Good evening, Kraftwerk!

““Here in the European Columbus laboratory, the successor to the Spacelab, the European Space Agency ESA is researching things that will improve daily life on Earth. More than 100 different nations work together peacefully here and achieve things that a single nation could never achieve. We are developing technologies on board the ISS to grow beyond our current horizons and prepare to take further steps into space, to the Moon and Mars,” Alexander said.

However, as Kraftwerk founding member Ralf Hütter emphasised, Alexander’s appearance was not only about greeting Kraftwerk and the audience in Stuttgart but also about “music as the universal language of the world”. After addressing the crowd, he and Alexander played a special duet version of the track Spacelab, for which Alexander had a tablet computer configured with virtual synthesizers on board.”

“Nachdem Alexander Gerst sich mit einem „Good Night Earth“ vom Publikum verabschiedet hatte, fuhren Kraftwerk mit ihrem fulminanten Set fort, während die Zuschauerinnen und Zuschauer sich wohl noch ein paar Mal verblüfft fragten, ob das, was sie da gerade gesehen und gehört hatten, auch wirklich live und real war. Wir können sagen: Das war es.”

This has got to be one of the most amazing things done with a 3D camera I’ve ever seen. Pro tip: Watch this in fullscreen mode on your phone so you can look around by moving the entire phone, and use headphones to get the full 3D sound effect as well.

Make sure to also watch

Henry Segerman: The Making of “Peace for Triple Piano”. (YouTube video, 13:52min including a “flat” version of the above 3D video).

In this video Vi Hart and Henry Sergerman explain how the video works: how they made one grand piano and one Vi look like three, but one Henry look like only two at the same time.

Vi writes a little more about this project on her weblog: Vihart.com: Peace for Triple Piano.

(This was published back in February, but I only now realized that the RSS feed of this YouTube channel stopped working.)

XKCD What if: Earth-Moon Fire Pole. “My son (5y) asked me today: If there were a kind of a fireman’s pole from the Moon down to the Earth, how long would it take to slide all the way from the Moon to the Earth? – Ramon Schönborn, Germany”

I loved this and am tempted to use it in one of my next physics lessons…

OK Go: The One Moment – Official Video. (YouTube, 4:12min)

A music video that was shot in just four seconds and then slowed down to fit over four minutes of music. Here’s how they did it:
