Patrick, that's not too shocking. Many young EE people can't even read color codes on resistors. When they pick up a capacitor saying 473, they don't know what it means. There are many these stories. To those people, you don't show them something saying "12AX7" and expect them to know what it is.(posted 8075 days ago)Let's talk about photo-related thing. The population that even recognize silver halide cameras is shrinking rapidly. Even those who know EOS-1 or F5 or something, many don't recognize Copal metal square shutter or #1 lens shutter as a shutter mechanism! You show them how mechanism works, and explain the self timer unit compared to old mechanical wakeup alarm clock. Don't expect they know what you mean!
There are many many many of these.
We just don't need to know them.
I have a mini collection of old tube devices and a boxful of tubes. My old university wrote off many of those measurement devices in the lab and I took some of the nice ones. These days, people are getting rid of CRT's, leaving only magnetrons in the lab's kitchen. However, I use automated data acquisition, recording, etc. for my research. For the same reason, I wrote a postscript program to make semi-log paper out of the laser printer, but I don't use it for actual work. I either plot data electronically, or I just pick up a sheet of scrap paper, draw log graduation with a pencil - 1.5 digit accuracy is often good enough.
Please don't think I just don't use Photoshop. I should have said I have the same LE version of Photoshop, which came with the scanner, but I never installed it. I don't use a Microsoft product nor an Apple product.
Please don't tell me to convert to Microsoft platform unless you are prepared to be told opposite.
