@furnaceop42 How can a drill possibly cut a hole through a brick?! Ancient medieval walls are impenetrable. That’s how they kept the Huns out, or something.
@furnaceop42 Not *quite* that fancy! It’s a Skil; I was considering the hammer drill but the masonry bit I bought says to use with rotary drills only. Oh, well, maybe next time. ;)
🚀 From America’s rails to the moon! 🌕 Built by @WabtecCorp and unveiled with @northropgrumman , our newest commemorative locomotive #up4547 began its first mission hauling @NASA Artemis III rocket components, powering the next era of exploration.
Former NASA astronaut Doug Hurley captured it well at the unveiling ceremony: “Together, we are taking the next leap for humanity.” https://t.co/X9rN4NDS70
I was reading a paper on early radiology used during the Spanish–American War era and came across an image showing a severe radiation burn on the chest of Pvt. T. McK., a U.S. soldier.
According to the paper, the injury occurred in 1898 after multiple long X-ray sessions including three 20 minute exposures at very close range for diagnostic imaging. There were NO dose limits and NO lead shielding back then so the burn progressed through severe reddening, blistering, ulceration and eventually tissue necrosis. The radiation burn did heal though, but it took about 11 months.

@Black_Kettle@allie__voss Yes, rather common. We’ve got two, I think because of duplicate wedding presents. I’m not sure if I’ve ever seen one over here that’s a standalone type, unless my daughters had one for their college dorm rooms. No stoves in those.
