Stupid Questions May 2015

This thread is for ask­ing any ques­tions that might seem ob­vi­ous, tan­gen­tial, silly or what-have-you. Don’t be shy, ev­ery­one has holes in their knowl­edge, though the fewer and the smaller we can make them, the bet­ter.

Please be re­spect­ful of other peo­ple’s ad­mit­ting ig­no­rance and don’t mock them for it, as they’re do­ing a no­ble thing.

To any fu­ture monthly posters of SQ threads, please re­mem­ber to add the “stupid_ques­tions” tag.
