This topic chosen to satisfy an e-mail request. It is entirely possible to calculate square roots without the aid of an electronic or mechanical device more advanced than a pencil. More on this, and about choosing content, frequency, and presentation of these lessons comes after the break.
The complete details for calculating square roots by hand can be found here.
As mentioned before, if there are any topics in physics, math or education you’d like to learn more about, let me know, either in the comments or by e-mail. If I don’t know how to do something already, I’ll probably be willing to learn. (I’ll also pay attention to “me too!” posts supporting the same idea.)
Questions for readers: how often do you want these columns to appear? If there seem to be enough topics to keep things on a semi-regular schedule, would you like that, or should I stick to the (more manageable) schedule of doing the columns as the requests come in and my time allows, so they’d end up coming out at random intervals? Also, would you like to see the columns collected on a sidebar page with the event calendar, chatroom link, and so forth? In short, what do you want these columns to become?
