Re: My $165,000 VNA


 

Read Grumpy Old Man,

I was a family doctor (the old fashioned kind) for 44 years, but sincerely wished I had known about computers and how they worked before I got into medicine. Just the excitement of what computers can do in medicine might have called me into research in using computers in medicine. Our chemistry professor, Max Thomas, brought a small lucite box into the lab one day and tried to tell us this was the future but I was too busy learning medicine and ham radio was enough to satisfy my nerd instinct. His black box was a four bit computer with sensors to read the pencil lead marks on out test papers and blink out the results in hex on the top of the box. He had made it himself..... we thought he was weird.

Such is life.

Now I struggle to learn a little about the digital side of radio. Exciting none the less but I am so far behind. Just don¡¯t have the mental energy to struggle with it too much. The younger set is trying to teach me though.... not completely hopeless.

?Further thoughts on the above.

As a doctor, I started my training by learning anatomy, physiology pharmacology and biochemistry, before ever going near a patient. I needed to know the basics of how the body worked.

A computer engineer might benefit from understanding how digital logic and circuits work, and a bit about transmission lines, in view of the high switching and data speeds. Somebody has to know enough to actually design and manufacture these computer processors. A programmer might benefit from knowing what happens at machine level, machine code etc. Somebody has to write the fancy Python, C+++ etc compilers, and even a simple boot loader for our vnas.
