#Germany summons #China’s ambassador after military aircraft lasered in Red Sea

A #maritime #surveillance aircraft was part of #EU mission #Aspides, which is intended to better defend #civilian #ships against attacks by Yemen’s Houthi rebels.

It was #lasered earlier this month “without any reason or prior contact” by a #Chinese #warship that had been encountered several times in the area, the German Defence Ministry said.

🕺 Dance your PhD!
Science communication can be a lot of fun — as recently demonstrated by our grad student Arfor Houwman, who produced a short dance video to explain his PhD topic in #QuantumPhysics. He even won an international award by AAAS and @SciMag for the clip (category #Physics) , so we highly recommend checking it out!

All we've gotta say is: lasers, lasers, lasers - LASERS!

Wow, this sounds kind of exciting.

Steps towards creating a Thorium Nuclear Clock and using it to measure the Fine Structure Constant carefully enough to see if it is changing (there has been some evidence that it might not be truly constant). Which is a scary wild thought, actually.

I feel like there's a Doctor Who premise in here somewhere!

Fedi xmas redux: posted this last year on an old account.

Happy Xmas mastodon, here's a small gift.
I won't be able to continue with my #makerspace activities, so I'm offering up the training materials I made for any other makers to use for their grasshoppers. All of the info specific to our space has been taken out, so you can put your own info in!
These docs cover #welding (MIG and TIG), #epilog #lasers , #prusa #3dPrinter , and #Formlabs #ResinPrinter , and pair well with @sjpiper145 skill trees for makers!
Happy making!

"These documents cover safe use of the Prusa i3 MK3S and basic 3d printing concepts, safe use of the Epilog Helix 75w and Epilog Fusion 120w lasers, safe use of the Form 2 resin printers and resin printing concepts, and basic safety and concepts for MIG and TIG welding. They can be used for training by yourself, with students, in a #makerspace , or a classroom, and can be used as a template for your own training documents for other models. This was shared by the creator of the document and is free to use. If you make a new document with different equipment, please allow me to share it too in the spirit of #skillsharing . Thanks, and happy making!"

From @thebaldgeek (2 days ago, probably a helluva lot more now)

This is really upsetting.
There are 94! msg with the word 'laser' in my ACARS msg database right now. I have never, ever, in 7ish years, seen so many uses of the word before!
Look at the scroll bar how often they show up!
The whole drone thing is out of control.
DO NOT SHINE anything into the sky!!!

Space startups in Japan and India said on Tuesday they had agreed to jointly study using laser-equipped satellites to remove debris from orbit, an experimental approach to the increasingly imminent problem of orbital congestion. japantimes.co.jp/business/2024 #business #companies #space #india #startups #lasers #satellites
