PickVidsAdmiral Grace Hopper Explains the Nanosecond
推荐理由
Admiral Grace Hopper Explains the Nanosecond" is a good illustration of this (segment is only 2m)
说明
这是2012年由funbury发布的一部课堂讲座，主题归在History of computing。它讲的是latency and the speed of light这一支里的具体问题，而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成：Admiral Grace Hopper holds up a length of wire to show how far light travels in a nanosecond, about 11.8 inches. She explains how she made the idea concrete to people who could not picture a billionth of a second.这些读者给出的理由，核心是：HN uses it to illustrate physical latency limits and why performance and distance matter in computing.讲法不绑某一条新闻，过几年仍然可以当材料看。从2020年到2025年，有5位不同的读者在5个不同月份把它推荐出来，其中明确叫别人去看的有1次。节奏接近上课，可以暂停做笔记。它假设你愿意跟着一条推导走完。如果已经会了基本定义，就把注意力放在它怎么把latency and the speed of light变成能跟着复述的例子。
