The theme this week is by Gail's Man which is "Technology". Mac, Gail's Man, Lanny, Dave and I have a little contest to show a new theme header each week. We now post anytime before 4 PM EDT and voting begins after that.
Talk about a theme right in my comfort zone. It was 50 years ago that I started my Mechanical Engineering college education. Has the technology changed in that time. Why yes!!!!!!
The first years of college I used a slide rule to do my calculation. I had a Post bamboo slide rule which I have kept. It still works and I have it set to 2*2 which equals four. A slide rules accuracy was based on where you calculated the answer on the slide rule. The left side was much more accurate then the right. Here is a photo of the slide rule.
After I started working I was able to purchase a calculator which you could work on your mathematical problems. I no longer used a slide rule. I paid $150 for a calculator which would could buy today for $10. I bought a TI30 and it was similar one to this one.
The work was done by hand on a drafting board and I had drafters to make the final drawings. When I left the Engineering profession I did the design on the computer and did all the drawings myself with the help of Autocad. My Dell laptop is much more powerful then anything I ever used to design. This is what I used for my header. I don't do designs any longer but do a lot of other things on my computer.
