So he probably remembers.
It's true. My Father could visualize the solutions to partial differential equations, but not a car engine.
The next step up is if one can visualize a machine running, and "see" which component is making a funny noise. The strongest version is being able to diagnose problems in passing cars by their sound alone.

Not a tweak, but a whole complex system designed by committee, and which the entire world is using. The USA and everybody dropped their own systems and switched to GSM.
But not in Phil Hobbs?
I know people who text (or talk) constantly. Verbal people.
I sketch pretty much constantly, scribble schematics and mechanical things. That uses a lot of paper.
People are so different.
Found something related to this the other day, in my news feed by Google:
Spanish:
Theoretical physicist Michio Kaku summarises in a brutal video lasting just a couple of minutes the scientific and economic nonsense of the US Republican Party, which is accelerating the decline of the American empire and China's rise.»
The complete version (9 years ago):
For "moving" you need javascript, AFAIK.
Ffx does have javascript, but the implementation is buggy or "different", dunno which.
I tried to watch it in FFx.
Now I tried to download, which worked instantly and allowed me to play the video. Yes, very interesting features. I should have thought of that before.
Support of javascript in PDF viewers is limited, or non existing, and this is intentional because it is a security risk. The only viewer that I know tries to support it here is Firefox.
I just tried the FireFox route you suggest, and it worked for me as well.

Why? Both are strings of ascii bytes. Images take more room to store. None take meaningful space to store or transport these days.
Creating schematics takes more skill than typing c, which is why 95% of ee grads are now typists and typically afraid of electricity.
And, I guess, why most of the posts to s.e.d. now are about coding.
How do you organize them?
No. I don't code much these days; I have kids to do that. I've written three compilers, four RTOS's and most of a milion lines of application code, mostly in assembly and various flavors of Basic. But I find architectures and hardware design to be more amusing and more profitable.
Interesting circuit design does not involve connecting a few high-level black boxes.
Rs and Cs and Ls and transmission lines and basic active parts are more interesting. And in fact more complex. There aren't a lot of exciting ways to connect a uP chip to an SPI part.
Seems that way lately.
We make a company-wide backup once a month, on a couple-terabyte USB hard drive. We stash them in various places in California. I occasionally pull out an old one and none has failed.
We'll eventually cut over to usb memory sticks, when the price comes down.
We have rules for documenting parts data, experiments, prototypes, and deliverable products.
Phhht. The city of Munich tried that many years ago. Failed.
It's not that it can't work. I have completely switched to Linux when Windows 7 was retired. However, it comes with a lot of compatibility issues and other problems that require expensive experts to fix them.
I think Fleming in the UK made the first practical vacuum tube :-)
Germans made the first jet fighters but they were on the wrong side so that got stopped by force.
And the Russian will claim that they had already invented it before Catherine the Great. Then China takes it over, produces it for 25% of the cost and it shows up on EBay.
Having lived in both places for decades I observed that there is a huge difference in the venture mindset. In people, in banks, in government, everywhere. I have tried starting a company in Europe (didn't work, couldn't secure enough funding) and in America (it worked, funding was no problem).
If Europeans had less red tape they could invent at the speed we do. They have capable engineers.
Yes, they are. And there is a lot of stuff from Honeywell, Harris, Collins and so on in their aircraft.
Well, Edison first.
The Fleming valve didn't have a lot of gain.
It's easier for un-credentialed amateurs to start a company here. Apple, google, like that.
We sell a little to Airbus and Rolls.
ASML is the giant european success story. ST and a few other semi outfits are good too.
Americans did not like Bill's posting in this thread, maybe too busy watching the job numbers tank under Der Leader's exceptional guidance.

Fleming invented the diode. He knew what it did and worked out why it did it. Lee de Forest made a triode and patented it - but he didn't know what it did and didn't care, just as long as he could claim the royalties when someone else found out that it was useful.
On the other hand, when my wife got her (Dutch) Spinoza prize for psycholinguistics in 1999, one of the other three prize winners was the guy who had invented the composite "Glare" that provides the skin of the Airbus A380. He wasn't the sole inventor - the composite has a long history of development in the Netherlands.
Edison discovered the diode effect. The Fleming tube was just a mediocre diode. The deForest thing had gain and made electronics happen.
Often it helps to understand why things work, but it's not mandatory. What's important is that it works.
One can argue that none of us, scientists or hackers, really understand how things work.
But there are degrees of understanding, and getting a better understanding is often the key to making things work better.
Your irrational anxiety about the imagined destructive effects of vacuum desication is exactly the kind of thing that gets in the way of making things work better.
and about 95% of them got bust.
Red tape doesn't get in the way of invention. It's always a problem during development, and the US doesn't seem to have much less than any other advanced industrial country.
And when I was working at Cambridge Instrument we sold a lot of stuff to IBM, RCA, Fairchild and Texas Instruments.
We even sold an electron beam microfabricator to the Victorian Mint in Australia,who used it to write the holograms that get pressed into Australia's plastic currency notes, and a bunch of other they make for other countries.
ASML is a Philips spin-off. Philips was a useful semi-conductor company, and did a lot of development. Cambridge Instruments took over their electron beam microfabricator - it was a perfectly fine machine but Philips didn't support it as well as it needed to. Cambridge Instruments had a long history of doing that, and were pretty good at it.
I have never mentioned vacuum desication. You have to imagine things to deplore me for.
And why would desication make anyone anxious? Bored maybe.
We have an oven to dry things, and our pcb water wash machine has a dry cycle too.
We have used vacuum degassing for epoxy, but it's messy and best avoided. Wet stuff in general is messy in production.
ASML got their EUV (and MOPA DUV) technology by acquiring Cymer, in San Diego. We supply timing controllers and metrics for both.
Intel kicked in a gigabuck or so to help fund the Cymer purchase, but then somehow failed to implement EUV in production. They spent the money on stock buybacks.
The high-NA EUV scanners, the latest generation, cost something like $300M each.
