But they never really tried that either. AFAIK, the SSME are the most complex engines, of any type, ever made and also the most efficient. Performance was their goal, not reuseability.
I'm sure they could have done this by the 70's if that were their goal. The essentially did the same type of control landing the LEM on the moon (controlled flight of a balanced rocket). In fact it's more difficult to control something short like the LEM where the CP and CM are close together than a long cylinder. At least mathematically, they each have their problems. But they opted for wings which may or may not have been a correct decision based on expected missions.
I hate the lower classes too and wish no one were lower class. I guess if you love lower class people, then you'd like to see more of them. I love pizza and am always happy when I get more.
Neil Postman has an interesting take on this. It's not so much a concerted effort on the part of trolls, but by the inherent nature of the medium itself. Take television vs newspaper for example. I recently found a newspaper of Kennedy's assassination in a box of old papers. It's pages and pages of dense tiny text and allows for in depth detailed analysis.
Television, by its very nature cannot do this. No one would listen to three hours of minutia of some guy reading a report and would insead turn the channel to watch the Flinstones. So the news has to be dumbed down an filled with color animation to stay relevant. What happens when this goes on for a couple of generations? Eventually you are left with a populace incapable of articulate thought.
Why would you want to stay in the US regardless of 9/11 after the scsc was cancelled and cern was ramping up lhc? I knew half a dozen grad students pinning their theses on the scsc who transferred briefly to batavia before heading off to wall street.
The problem with Galileo was not heliocentricism which was generally accepted by the church at the time, but by his end run around the pope to publish the work and not going the church bureaucracy route. Also, the big bang was proposed by a Catholic Priest physicist,Georges Lemaître.
Which is the 'our' generation? I was in school in the 70's and it was horribly bad. I knew far more about science thingys by the second or third grade than any of my teaches until I got to high school. Because I could read and did, while they didn't.
And the US got to be #1 thanks to WWII where we imported most of the science from the UK (radar), other parts of Europe (nuclear bomb) and an untapped and undesecrated manufacturing base. Our space program was a 99.8% continuation of the Nazi program under von Braun and the US lagged Germany in aerotech thanks to it's (Germany's) militarization and buildup starting a decade earlier, not even counting the German experience in the Spanish Civil War.
Another factor is standardization and commoditization. I've been working in engineering for almost 30 years. Back when i started, many parts in my field were new and unique and products were designed to this. As an example, I watched a video last month of a teardown of a video camera from the 80's. It had dozens of specialty parts made specifically for that model of camera (including electrical components I'd never heard of before). An equivalent (but better) camera would be made today with nothing more than a reference design from a chip datasheet and a bom from digikey.
I've seen, and built many, arduino projects, in a few hours I might add, that 16 years ago took me and a team of 5 other people almost a year to complete. We had to invent a number of tricks to get certain things to actually work on the available hardware of the time. Now half of our work is accomplished by a $4 - 32 processor and the magic we had to do is now an interesting footnote of obscura.
Then there are upper levels of product quality you need. Say you were building a digital thermometer for a car. It might be (was) a herculean effort to make a sensor with.1degree precision, and there might be dozens of customers who want it. But once that is done the market is over. No (similar industry) customer would ever want a sensor with 0.01degree precision, the economics are not there. Even if it was, it would take one person a week to design and test. I watched a video his morning of people doing things with free software for astronomy that I worked on for years in college. A motivated 5th grader today can put together a media center for $70 that would rival a top of the line system from the 90's. How much better (functionally) is a media center from 2015 than one from 2000? I have countless examples everything that I look at and all products around me. Why would anyone continue to pay me $150k/year for something that can be done similarly by an 8 year old?
Not comparing apples to apples. A 1938 house is nowhere equivalent to a 2015 house. In fact yesterday I was looking at a house built in 1939 and was estimating the costs bring it up to modern codes. Even when this was done, it would be a crappy tiny house that few would want in a nt too bad of area.
They have far more people. They are just as smart as us, and they will work for less.
I read this exact same thing back in the 80's on a panel discussion of the US in a developed world, so at least some have been expecting this for 30+ years. I guess the future really is here. Those that can adapt will do well, those that can't, maybe not.
If the premise is to truly ask a question, they would be asking it to engineers, not a public forum. If the premise is to create some sort of fear and or outrage to boost sales of their magazine, then it makes more sense.

Fine with me, I used to work at a nuclear site so it would not be any different.
Yes. There is economic disincentive to reuseability if you are a manufacturer. Why build one rocket when you can build 20?
NASA never achieved that
But they never really tried that either. AFAIK, the SSME are the most complex engines, of any type, ever made and also the most efficient. Performance was their goal, not reuseability.
I own a corporation. It cost me $35 in filing fees and $700/year to maintain it. What can my corporation do?
This seems to be one of NASA's primary missions of the last 40 years.
Proving that you can do something is engineering v&v, not science.
You do it now on Earth.

Electronic parts (like pcbs and stuffing) haven't been close to each other since at least the 80's.

How did they get $1M dollars?Maybe by providing something of value to 1M people. If you are providing the same value, maybe you should up your rates.
Don't go into electrical engineering

No, everybody. You just need to pay teachers more.
your property won't even exist above water 50 years from now
This was taught in schools in the 70's. The end is closer than you think.
