For example, it is implied that hydrogen maser clocks are less expensive than caesium clocks.

More organization is needed to make this section comprehensible, which can be remedied with a new page. </p><p>'Gas giant' for example is not a subsection of the 'planet' page. 'Gas giant' is it's own page. Gas giants are a subsection of planets, and optical clocks are a subsection of atomic clocks. When a page grows very large, and a certain subsection still has ample potential to grow, that subsection should be made into it's own page.

This article's prose size, 43kb, 6800 words, is not at the recommended splitting threshold, but if it had to cover the rapidly expanding field of optical clocks I think it would quickly reach that size. I think this article should be expanded to discuss many points about atomic clocks the current text leaves out: Why is caesium still used after 70 years? What are the advantages of rubidium? Why do hydrogen masers have superior short term stability? What was the <a href="/wiki/Ramsey_interferometry" title="Ramsey interferometry">Ramsey interferometry</a> breakthrough by Norman Ramsey that made practical atomic clocks possible? Why is a long drift period, as in atomic fountains, important for accuracy? What is laser cooling? If optical clocks are not split off this article will reach excessive lengths. --<a href="/wiki/User:Chetvorno" title="User:Chetvorno">Chetvorno</a><sup><small><a href="/wiki/User_talk:Chetvorno" title="User talk:Chetvorno"><i style="color: Purple;">TALK</i></a></small></sup> <a href="https://en.wikipedia.org/wiki/Talk:Atomic_clock#c-Chetvorno-20241009062000-Rat_eating_man-20241009003000" class="ext-discussiontools-init-timestamplink">06:20, 9 October 2024 (UTC)</a><span class="ext-discussiontools-init-replylink-buttons" data-mw-thread-id="c-Chetvorno-20241009062000-Rat_eating_man-20241009003000"><span class="ext-discussiontools-init-replylink-bracket">[</span><a class="ext-discussiontools-init-replylink-reply" role="button" tabindex="0" href="">reply</a><span class="ext-discussiontools-init-replylink-bracket">]</span></span><span data-mw-comment-end="c-Chetvorno-20241009062000-Rat_eating_man-20241009003000"></span></dd></dl> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Splitting_proposal" data-mw-thread-id="h-Splitting_proposal-20241009003600"><span data-mw-comment-start="" id="h-Splitting_proposal-20241009003600"></span>Splitting proposal<span data-mw-comment-end="h-Splitting_proposal-20241009003600"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Talk:Atomic_clock&action=edit&section=10" title="Edit section: Splitting proposal"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span><div class="ext-discussiontools-init-section-bar"><div class="ext-discussiontools-init-section-metadata"></div><div class="ext-discussiontools-init-section-actions"></div></div></div> <p><span data-mw-comment-start="" id="c-Wesoree-20241009003600-Splitting_proposal"></span>The section, <a href="/wiki/Atomic_clock#Optical_clocks" title="Atomic clock">Optical clocks</a>, can be split into <a href="/wiki/Optical_clock" title="Optical clock">Optical clock</a>.
