This is the intuition the new API tries to preserve: streams should feel like iteration, because that's what they are. The complexity of Web streams — readers, writers, controllers, locks, queuing strategies — obscures this fundamental simplicity. A better API should make the simple case simple and only add complexity where it's genuinely needed.

Leonardo da Vinci is usually credited with conducting the first systematic study of friction in the late 15th century, a subfield now known as tribology that deals with the dynamics of interacting surfaces in relative motion. Da Vinci's notebooks depict how he pulled rows of blocks using weights and pulleys, an approach that is still used in frictional studies today, as well as examining the friction produced in screw threads, wheels, and axles. The authors of this latest paper used an experimental setup similar to da Vinci's.

一開始我被刻意不告知任務的目的。但研究人員後來解釋，這些任務是為了啟動我大腦中的「跨情境學習」（cross‑situational learning, CSL）能力：也就是我們天生、直覺地利用統計資訊，逐漸推敲單字意義與基本文法的能力。你可以在這裡深入了解語言習得中的統計學習，但簡而言之，它指的是大腦根據語音中出現頻率，去辨識語言中的規律與模式（例如哪些字常一起出現）。
