A bit of bragging

Guess who made it onto Wired‘s frontpage?

Check Out This Tiny 3-D Printed Spaceship

“The tiny spaceship in the video above was built using a microscale 3-D printer. At 125 micrometers long, the craft is about the length of a dust mite, and it took less than 50 seconds to produce. The super-fast, high-resolution printer that made the spaceship was introduced this week at the Photonics West fair by Nanoscribe GmbH, a company based in Germany that specializes in nanophotonics and 3-D laser lithography.”

My husband built the machine that built this tiny spaceship! :-)

[A few hours later:] The tiny spaceship is also featured on Gizmodo: Watch These Lasers Print a Microscopic Spaceship In Under a Minute.

I wish I could do experiments like this at school.

MetaFilter: For no other reason other that we thought it would be quite nice:

A scientiest, liquid nitrogen and 1500 table tennis balls (video).

A shorter version without the explanation is here.

Sad news

Sunday, August 26th, 2012

Neil Armstrong, the first man to walk on the moon, passed away yesterday.

Some relevant videos:

  • Apollo 11: Prelaunch Press Conference / EVA Training (1969)
  • Landing of the Apollo 11 lunar module
  • “One small step for a man, one giant leap for mankind”
  • Armstrong’s message of thanks after leaving the moon surface
  • BBC interview with Neil Armstrong from 1970
  • 60 Minutes interview
  • The Bottom Line Interview (posted previously)
  • I also highly recommend the HBO series From the Earth to the Moon (I’ve got it on DVD), the part about the Eagle landing is available online.

    The Big Picture: Remembering Apollo 11.

    Statement from his family:

    “For those who may ask what they can do to honor Neil, we have a simple request. Honor his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink.”
