This was the graph we had at the end of the first day of data analysis on our distance and time data sets from Tracker on the falling Angry Bird. Note that Microsoft Excel has been able to fit a parabola very closely to our data. We're going to start tomorrow by trying to get the slope at each data point (to generate a (t,v) graph) and to start explaining what each term in this polynomial means, physically. Note that I had students take a screenshot of Excel before leaving class. Because we're going to continue to manipulate the data, this is good practice just to make sure we don't do something to delete the data.

Lesson for learners

Editing a spreadsheet in Google Docs is very similar to editing a spreadsheet in Microsoft Excel

This is a set of photographs from the Lotus Development party celebrating 25 years since the company was founded in 1982.

I worked at Lotus from 1988 to 1993, at the height of popularity of the Lotus 1-2-3 spreadsheet application. During this same time, the product Lotus Notes, the first widely successful network based application, was launched.

Since then, 1-2-3 was eclipsed by Microsoft Excel (and more generally by the Microsoft Office Suite). Lotus Notes, however, found long term success as a groupware/collaboration application, now part of IBM.

There is an excellent history Lotus Notes here.
