This sounds sort of like a scramjet.

Marconi sending a radio signal across the Atlantic is a good example of an engineer doing something that the scientists said was impossible.
Since the earth is round and radio waves travel in a straight line, it should have been impossible to send a signal more than a few hundred miles.
In fact, they bounced off the ionosphere, which hadn't been discovered yet.
In Newfoundland, the receiving end of Marconi's experiments, the undersea cable company, who had a legal monopoly on all trans-Atlantic communications, discovered or not, got an injunction forcing Marconi to stop his experiments and move elsewhere.
Marconi licensed, not sold, his radios, with a legal restriction prohibiting them from being used to talk to non-Marconi radios.
OTOH, in the 19th century there were several inexplicable observations, like the orbit of the moon. All except for the precession of Mercury eventually had classical explanations.
PNAS (Proceedings of the National Academy of Sciences) is an easy place for National Academy members to publish their papers. While their papers are externally reviewed, I don't think their papers always get the same rigorous review process that might happen at some other journals. It's a way for NAS members to publicize what they think is important.
Not true, at least in cities.
The VW scam was uncovered in Europe because German cities' air was not getting cleaner, as it should have been as the cars were supposedly getting cleaner. So, the EU version of the US EPA measured tailpipe emissions on the streets, perhaps with a laser. This was years before the US discovered this. The problem was that hi levels inside the EU decided to ignore it.
Two New York State police from Troop C (Binghamton) were convicted and jailed for spoofing fingerprints (and possibly other physical evidence) about 20-30 years ago. IIRC, they used scotch tape to lift the print of the innocent person they wanted to frame and then deposited the print on the piece of evidence connected to the crime.
So, even w/o using computers, fingerprints can be faked. Physical evidence is not as solid as prosecutors claim, but we already knew that from several other convictions for faking evidence. However NYS troopers are, as a group, ethical.
But, fingerprint readers do look cool.
From the linked article about deaths from GPS in Death Valley NP:
The mapping people at the National Parks Service were unable to contact a human being at Google to update their map, but could talk to Tom Tom.
I've heard that story also from other professional source.
That doesn't absolve stupidity, but still, it's nice when maps mark the important stuff. But then, Google maps violates most of the rules of good cartography.
Garmin's response to someone following their GPS half-way under a low bridge was, "Would you follow your GPS through a red light?"
Math is also fascinating because of how it can often work around impossibility proofs.
E.g., what class of polynomials is solvable depends on what elementary functions are allowed. With Jacobi theta functions, you can exactly solve quintics.
For another example, with cosine and acos, you can exactly solve cubic polynomials, w/o using cube roots. Better, if the solutions are real, then the solution does not require imaginary numbers, unlike if you solve with cube roots.
Making a false claim on a resume, even if not caught for years, has, in the last few years, gotten a senior MIT administrator and a company CEO fired.
The federal government sometimes checks items that are 20 years old on your resume.
Using an unaccredited PhD got some Ryerson University faculty in public trouble.
Don't even mislead or be ambiguous. If I read a resume that says, "attended Miskatonic", I assume 2 things. 1) The writer didn't graduate. 2) He wants me to think that he did.
Do not say that you attended Harvard if you went only to the Summer School.
Know your market. Some places value the degree quality and some do not. In the latter case, WGU or Excelsior are fine.
CS accreditation is optional and sets only a very low bar. MIT was not accredited until relatively recently. Accreditation is a hassle and everyone already knew that they were good.
Engineering accreditation is not optional. Stanford was threatened with losing their EE accreditation if they made a proposed change that probably would have been an improvement.
Vermont Yankee is also a lying incompetent organization.
In 1776 the Magna Carta was 550 years old. It had nothing to do with democracy, but supported the barons against the king. That was arguably a step backward. It became (wrongly) associated with democracy only hundreds of years later, when people were searching for precedents, even flawed ones, to support democracy.
Also, in 1776, most people in England did not have a vote. Look up rotten borough. There were three major reform bills in the 19th century that basically brought democracy to the UK.
In addition to plagarized theses, there are a lot of completely fictitious degrees being flaunted.
A few years ago a senior MIT administrator had to resign.
Last year there was the CEO of a tech company.
About 30 years ago, the President of the IEEE claimed to have a doctorate from a minor German university, but no one could find any record of it. However, his friends rallied around, and he was given an honorary doctorate.
Then there are the unaccredited doctorates. E.g., when Ryerson Polytechnic Institute was transitioning to Ryerson University a few decades ago, many of their faculty did not have doctorates. RU strongly encouraged doctorates, so a bunch of faculty got them from a degree mill in central Europe.
Finally, there's the faculty member at The King's College in Manhattan who lists himself as PhD, Princeton (ABD). ABD means that he does not actually have a PhD, but many readers might not know that.
Doubt isn't the opposite of faith; it is an element of faith. - Paul Tillich, German theologian and historian
