Okay, here goes nothing. My small take on the Excel story.<p>The year was 1986, pre-spreadsheets. Writing up an undergrad physics experiment in 1986, I needed to do a hundred or so similar calculations and present the results in a table. Luckily, a computer science acquaintance wrote a small program to do this task for me. Thanks, Dan.<p>In 1989, before Excel, there was Lotus 1-2-3. Loved that spreadsheet software. My PhD task involved plotting lots of data points, including smoothing some of them. Doable with Lotus 1-2-3, probably not doable otherwise.<p>More recent times.<p>Spaghetti Excel. An engineering acquaintance told me his student summer job, at an aluminum refinery, was to check and simplify their Excel spreadsheets. Apparently they had numerous spreadsheets linked to each other. I assume the main purpose was inventory control. I know I didn't envy him his task.<p>"Please, not just Excel." I took a class of high school students to a uni chem lab and had a small argument with a chemistry tutor who insisted the students use Excel to plot their data. I wanted them to first do it by hand with graph paper. This would have given them a much better feel for their data.<p>"Rinse-and-repeat Excel". I was tutoring a construction guy trying to learn maths. His job as an assistant on a high-rise construction job involved putting lots of numbers into an Excel spreadsheet. The check for this was to repeat the process and see if he got an identical result. I thank G*d his boss made him do this.<p>And that's it. Helped other people to use Excel, but I'm thankful that I haven't had to spend my life inputting data into spreadsheets.
