Physics

My wife of soon to be 27 years, went from nuclear engineering career to a career as a high school physics teacher.   Sometimes she will find a possible error in the text book and will ask me to look it over to make sure she isn’t doing something wrong.  She does the same for me when I have questions, so this is most certainly a two way street.

It took us 45 minutes to decide that the formula in the text book’s example problem is missing a minus sign.
