Will mounted ebonite disk <br />On smooth unyielding bearing,, <br />When turned about with notion brisk <br />(Nor excitation sparing), <br />Affect the primitive repose, <br />Of + and — in a wire, <br />So that while either downward flows, <br />The other upwards shall aspire? <br />Describe the form and size of coil, <br />And other things that we may need, <br />Think not about increase of toil <br />Involved in work at double speed. <br />I can no more, my pen is bad, <br />It catches in the roughened page-— <br />But answer us and make us glad, <br />THOU ANTI-DISTANCE-ACTION SAGE! <br />Yet have I still a thousand things to say <br />But work of other kinds is pressing— <br />So your petitioner will ever pray <br />That your defence be triple messing.<br /><br />James Clerk Maxwell<br /><br />http://www.poemhunter.com/poem/professor-tait-loquitur/
