Software is not magic. It is like any other tool or item of test equipment that has its limits and you really need to have an idea of what/where they are.
Friday nights a bit tricky for me….?Fair enough, if we don’t have a winning answer by Friday night you can give us a detailed explanation of how you worked it out ??
Ten to ten, ten to ten, ten to ten ten ten.......................Lone Ranger on his abacus??I sometimes see slide rules in the charity shops and it reminds me of precalculator. At school we were learning slide rules and using anti/log tables which I don't think they do nowadays do they? Slide rules, I just think they are so clever. I asked my teacher what was the answer to 10 x 10 to the power of 10. Mrs. White as I recall, a flurry of the log/anti log tables and she did it! I was captivated and impressed and determined to learn the mysteries of those pages, alas fair reader, I never did.
When I replaced my old Casio with a newer one I was really disappointed to see they revered the order of entry (oh-er matron!) as I was used to the older method when you used the function key to compute the action on the current display value.Although I have real difficulties using modern calculators tbh.
Exactly!!!When I replaced my old Casio with a newer one I was really disappointed to see they revered the order of entry (oh-er matron!) as I was used to the older method when you used the function key to compute the action on the current display value.
The older models worked very much like a CPU with the display as the accumulator register that stuff happened to/from.It used to be if you want the sine of 30 you entered 30 then sin, now you enter sin( then 30
The first is how my brain works, calculate the inner bit, then take the sine !
I think a lot is to do with how we oldies think about maths.The older models worked very much like a CPU with the display as the accumulator register that stuff happened to/from.
Actually that is another thing to throw in to the discussion - doing such electrical circuit mesh analysis by hand is similar to assembly language programming. Anyone who writes software should be able to do it and understand it so they grasp the basics, but nobody in their right mind uses it for anything where it could be done in a higher level language.
