I still have my slide rule from high school.
K&E?....
Do you have it stored next to your pocket protector ?
I bet you still know how to use it too.....I am not sure if it is good thing or not but it seems to me technology does a lot of thinking for students these days.....but then my son graduated with a degree in EE and in spite of technology he still had a number of long days in the lab and research in the library.....
