Wiltshire's (et. al.) more current work. I apologize if this has been posted somewhere else December 2024 popsci article Reference from that article https://academic.oup.com/mnrasl/article/537/1/L55/7926647?login=false

Perhaps.

I didn't mean to distract from the question. I started in ChemE, now I am HVAC. It's not exactly where I thought I'd be but it pays the bills. Sometimes just being able to pay bills is more important than what you do or want to. How you do it matters and will influence your compensation...

I'm a ChemE. Wound up in HVAC/Metal manufacturing. Honestly, I like scary stuff. Pyrophoric materials are interesting. Things that catch fire when struck are also interesting. I was a little dissapointed when I went to air. I like the smell of sulfur dioxide/trioxide.

Sounds good.

I don't know. Honesty is best, but there are some rivers you shouldn't cross, or try to. Sometimes, you should let it pass. I have some nice lawn equipment I use when the people with pitchforks come out (my wife). I can cut a lot of grass while she has her moment. If it takes a while, I can...

My wife's rear looks even better than it did when I was married (1992). Just get her to ask me about it. There is no correct answer in this case, just an opportunity for a redirect.

No shade thrown. I have a clean hard hat for pictures, and a real one for work (fits better, tighter to head, and is less likely to fall off). My past life involved a great deal of these folks that would show up for pictures, and then left when the real work showed, usually after a fire, train...

Call me cynical, but I doubt these folks have any hard hats, work boots, or gloves, of their own. They are probably the PR crew. Available for pictures, but not much else. I'd rather see cranes/jack-up rigs moving to pick up this mess. And, its a big one (mess, that is).

I have a pretty hard hat for pictures. I have a well used one for, well everything else.

Gotta be honest. New hard hats don't give me the confidence level that well used hard hats would.

Wow. A lot worse than the crawl on the local news was describing. I think the article said there were two pilots on board.

Welding Metallurgy, by Kou.

My favorite part of that scene is when Chewbacca pushes on the wall to "no avail" it is pretty clear he's moving the wall, or at least slowing it down. Probably was tough to film that on the budget they had.

I don't believe any common stainless steels (304/316/18-8......) will matter much. Not knowing the contact time, temperature, or concentration makes this difficult. First thought is to maybe going to a higher nickel alloy will help. Seems Carpenter 20, and one of the Hastelloy's are alloys...
