The UK MoD are looking at using #lasers. My criminal mastermind brain immediately had a single thought. Lasers would be defeated by mirrors. Weaponised disco balls fired by celebs. #weaponisedDiscoBalls
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!
#NASA 📆 July 12, 2023 #DSS23 started in 📆 February 2021 at the Goldstone, #California, #DSN Complex (with #OpticalCommunication
capabilities, which will be critical to communicate with #astronauts 👨🚀👩🚀 traveling to #Mars 🔴). NASA cannot use #RadioFrequency communications to carry higher data rates like those required for Mars without increasing
the size of its antennas 📡 or power of its radio transmitters. Therefore, the Agency is developing #optical communications (use
of light as a means of transmitting information through #lasers) https://oig.nasa.gov/docs/IG-23-016.pdf
This is Vietnamese laser programmer and performance artist Lại Trần Ninh Kiềm. He is doing some mind-blowing things with his art form.
The transition between environmental and manual control of the lasers is wild. And he has meticulous, granular-level control over the illusion. It’s quite remarkable.
A nice, easy to read, article on the history of cooling things with lasers.
"Although using energy to cool something is, of course, routine – it’s what happens in your refrigerator – there is something about the idea of using nothing but light to cool a gas of particles to temperatures a fraction of a degree above absolute zero that makes even experienced physicists scratch their heads."
High-power lasers at the US National Ignition Facility compress iron to explore the conditions prevailing in the core of an hypothetical pure-iron exoplanet.
