I also don't see the Preview Options Cancel button controls until I mouse over them when I post the comment after mod points have been used (this may be intentional).

Aside from corrosion, which is a solvable issue,
Someone I knew for a long time said, "If you want to work forever, study corrosion." Another quote, "Every metal seeks to return to the ore from which it came, corrosion engineers can only slow it down."
Regarding seawater, outside of the unsolvable corrosion, other problems will be precipitation of the salts within the piping, fish intrusions, and a lot of particulate matter that can erode the piping systems. But that doesn't mean you can't use seawater, you have to design for those problems, which costs money.
The atomic diameter of silicon (covalent bond) is 0.2 nm, the lattice distance between atoms is 0.5 nm. If they are moving to 7 nm, they are already ordering atoms at only a factor of 5 or so less than what is theoretically even possible given space requirements (I would think you'd need at least one atom between the gaps, probably more than that), so they'd need another material.
It amazes me that they can focus the lithography light so tightly.
There are several software products that have a per-use fee attached to it (TurboTax, for instance), as the creator you have the right to set the conditions for use, and the buyers have the right to accept or reject those terms.
Musicians and filmmakers produce a product that is license-based, when you buy a movie you get a license to consume the material as you wish. Those that use that license for commercial applications have to pay a royalty. Whether the artists are important or not doesn't seem relevant to me, someone is using their product for their platform's gain, and the owner of that platform should compensate them for it.
I'm assuming you weren't intentionally copying the premise of Idiocracy.
I know old school forensics teams put acid on the site and the cold-worked area would have more fractures in the microstructure which would reveal a scraped serial number. If they did this with EBDS, I would guess you could see differences in the cumulative cold work and still resolve the original pattern (you only need a few reference points).
If a criminal wants to use the gun, or bike, I'm not sure how much stamping they could do before they damage the material enough to prevent use.
Not sure if you have deeper sources, but the public line is that Armstrong was always supposed to go first, although Buzz definitely wanted to go first. They picked Neil because he was senior, and it would have been impossible for Buzz to crawl over Neil with his EVA suit.
But then again, if you know something, I'm curious.
While some people may find his actions cromulent, I personally think his work embiggens us all.
Probably closer to Lost in Space, but as a kid in a small school, the row of TRS-80s stood out as The Future, and I would spend all morning and lunch entering programs to run until one kid punched the rest button to piss you off...good times.
The old pyramid was one serving each of meat, vegetables, dairy, and bread. Now recommendations skew towards 50% protein, 35% vegetables, and small amounts of dairy and carbohydrates.
I put bread in the refrigerator, it keeps for over a week.
I think some of the issues are that:
-The necessary biochemistry needed to really analyze the effects of nutrition is still in development.
-Food processing in general is a recent adaptation (less than a lifetime), and the effects of it are just now being understood.
-The number of degrees of freedom (food types, component chemicals, varied responses to each chemical, factorial responses to multiple combinations, genetics) combined with the inability of really knowing what test subjects eat over a long time make rigorous experimentation impossible.
-The fact that the human body can metabolize so many chemicals effectively with such delayed responses...it takes years for someone who was thin to get fat sometimes. Many of the food companies know that Twinkies are delicious, and they were not shy about pushing that crap down easily impressionable young kid's throats.
It's getting more informed now, but if you look back the food pyramid wasn't necessarily bad, even today it's okay to have proteins, vegetables, breads, and dairy, it's the proportions and processing that are under scrutiny.
It's a shame, Radio Shack was so early in the PC game with the tape drives, 16KB of RAM, no hard drive, peek and pokes...they catered to the true tech junkies and with just a bit more business acumen, they could have ruled the computer world.
But then Commodore 64 came out with color and games, then came the the 8086 etc., but for a while the real eggheads knew how to play with the machine that looked like it came straight from the Star Trek bridge.
I don't disagree with your civics, but I'm also a realist. When I put money in a stock, I want the value to grow. That value is based on earnings per share and other technicals, and those technicals are determined from the annual cash flow. Cash flows are affected greatly by taxes, which are always represented as a cost. Institutional investors follow these cash flow tables closely, and their decisions are what determine the market price.
Our tax system is set up to tax high and then give credits/exemptions/loopholes to those who manage to influence the system. If it were set up where there would be relatively fair tax with fewer exemptions, it would be manipulated less and more money would stay here. Or maybe not, I'm not naive enough to think that they wouldn't find another way to pay less.
Dry air behaves ideally until several atmospheres at reduced temperatures well above one, we're talking about 2 atmospheres. Ideal assumption would be fine unless there is humidity. If there is humidity in the air, it gets a little more complicated; you'd have to subtract out the vapor fraction that may condense.
