<h1>Dividing History</h1>
<p><strong></strong>The list of books under the ((Directory)) at first glance seem to follow conventional views of history. This match happens only by coincidence. The books in the ((Measuring History Series))<em></em> builds on the matrix of ((Neptune-Pluto Waves)) listed below.</p>
<ul>
    <li><strong>((4540bce-4043bce)):</strong> First Agricultural Revolution/ Horses Domesticated</li>

    <li>((3552bce-3062bce))<strong>:</strong> Egyptian pre-dynas</li>
    <li>((3061bce-2563bce))<strong>:</strong> Bronze Age Begins/ Pyramids Built</li>
    <li>((2562bce-2049bce))<strong>:</strong> Sumerians Rise/Fall</li>

</ul>
<p>Some historical periods turn ou more dense than others. Other periods warrant study in longer or shorter increments; certainly modern history provides more material than more ancient ones. Most of these decisions reflect in the book titles (except the Primer), but readers should remember also that the book list is a projected one, nowhere near finalized.</p>

<h2>Measuring Across Time</h2>
<p>&nbsp;</p>
<p>To the inexperienced, most readers at this ponit. This choice of how to divide history may seem arrogant, but each Neptune-Pluto wave arrives with methods that break it into still smaller pieces. The fact that these methods work the same across any era provides an objective yet revealing way to view history. Soon, the logic of this choice may come to seen as the only natural choice. </p>
