re: What if I told you the most sensitive thermocouples, heat flux sensors, and radiometers...

Because you are speaking in generalities while missing the point, while acting like its profound.
Just because temperature inherently has a delay in detection time, doesn't mean there isn't a vast difference of engineering between sensors that can detect changes to a hundredth of a degree within a fraction of a second and one that can detect changes within a tenth of a degree within 5 seconds.

Without looking it up, what are the principles of a thermocouple
Two wires of a different material create a voltage and that is translated into a temp reading. Not very complicated.

wrapping wires the size of spiderwebs perfectly around other super small wires, etc under a microscope.

Yes, to me it wasn't crazy that it was made by a small business by just a few people... but that the shop had 1960s and 70s electrical equipment being used to test them, looks like a super cluttered mad scientist dark dungeon, etc.

Like I said the idea isn't complicated, but their sensitivity etc is very complicated.
No one else in the world has been able to duplicate them or even come close and lots have tried including SpaceX.
So, it's not as simple as some of you want to make out.
Eta, the size is also important. The main sensor that is embedded in most of the projects is the size of a grain of rice.

Flux Capacitors? Where da Flux Capacitors?

looking at the picture, a little left of center, upper shelf is a blonde wooden box that may be a Wheatstone bridge. Thats the apparatus used with a thermocouple to measure temperature. The one I have on my shelf was made in 1958.

Well the picture is a AI Bing generated image based on my description, lol
1970s electrical test equipment was was one thing I said.

umm yes there is

I seriously wouldn't doubt if the guy that came up with this stuff had one designed on paper in his cabinet.
The guy that owns it now said there were tons of designs and plans this guy had come up with that never got made, lol

That “is” was supposed to be “isn’t”
Corrected. Even though the context should have made the point fairly clear.

Why did you post an AI image?

From what he told me they didn't before he bought it and just upgraded them within the last 10 years or so, lol.
He said some of them you could hardly see through due to heat damage from soldering under them so long.

Cause what they do back there and how they do it is very secretive and I don't think he would have wanted me snapping photos.

Well it kinda is broke in some ways. Not broke, but time consuming.
One of the reasons I was there was to help come up with ways to speed up the process. They are very backlogged.

fair enough, just thought it was peculiar.

That’s some 1970’s analog looking test gear. Fake, but impressive for an AI machine. The flux capacitors in the lower right on the bench are a nice touch.

25 years ago I worked for a tiny operation in BTR, owned and run by an EE professor who wrote circuit textbooks. We assembled circuit boards that were used in the Mars rover, and the lab looked kinda like the pic in the OP.
