✈️ 為什麼搭飛機的時候，窗戶都是圓形的呢？
Notes de l’épisode
Why are airplane windows round?
🧠 好奇問題：為什麼飛機上的窗戶都是圓形或橢圓形的，而不是像房子一樣是方形的呢？
🎧 這一集在聊什麼：最早的噴射客機曾經使用過方形窗戶，但在高空飛行加壓時，方形窗戶的銳角會集中壓力，導致金屬材料容易疲勞損壞。後來工程師發現，把窗戶做成圓弧形可以讓壓力均勻分散，讓高空飛行更加安全。
👦👧 適合誰收聽：適合國小生收聽，也很適合爸媽陪孩子一起聽、一起討論。

🧠 Curiosity question:Why are airplane windows rounded or oval instead of square like the ones in our houses?
🎧 What this episode is about:Early jet airliners once used square windows, but repeated cabin pressurization caused stress to build up around sharp corners, wearing out the metal skin. Engineers discovered that rounded windows help distribute air pressure evenly, making air travel much safer for everyone.
👦👧 Who this episode is for:This episode is suitable for elementary school children and is great for parents to listen together with their kids.
