Things I Learned This Week

• ⛷️ Cross-country skiing (越野滑雪) is a winter sport where skiers travel across snow-covered terrain using their own movement, rather than relying on ski lifts (運送滑雪者上坡的滑雪電纜車) or steep downhill slopes. It’s one of the oldest forms of skiing and is known for being both physically demanding and deeply connected to nature. Practiced on flat or gently rolling trails in forests or open landscapes, it delivers a full-body workout that engages the legs, core, and upper body while providing exceptional cardiovascular benefits. Skiers typically use either the classic technique, which features parallel skis and a walking-like glide, or the skate technique, which is faster and more dynamic with a V-shaped motion.
• 槺（ㄌㄧㄤˊ）榔（ㄌㄤˊ ）樹：即「台灣海棗」，是冰河時期的孑遺植物，早期沿海常見的植物地貌，葉片可製成驅邪的掃帚。
• 自行車胎上的胎毛（vent spews / rubber whiskers）是外胎在硫化成型時的製造痕跡：模具裡會設計許多「排氣孔」，用來排出多餘空氣，確保橡膠能完整填滿模具，而橡膠在高溫高壓下會少量擠進這些微小孔洞，冷卻後便形成一根根細細的胎毛；因此，它並不是為了騎車性能而設計的，既不增加抓地力、不影響滾阻、不影響耐用度，也不影響排水或操控，並會在正常騎乘中很快磨損消失。胎毛唯一的實際意義多半停留在心理與辨識層面，作為「新胎指標」。胎毛多寡則與模具設計、製程與橡膠配方有關，與輪胎性能或等級沒有直接關係，因此無需特別保留或剪除。
• “Yikes!” (哎呀/糟糕) is a casual English interjection (感嘆詞) used to react to something that feels awkward, alarming, shocking, embarrassing, or unpleasant. Examples: (1) “Yikes, that exam was way harder than I expected.” (2) “He sent that email to the wrong person—yikes.” (3) “Yikes! Are you okay?”
• 華爾滋（Waltz） 是一種起源於 18 世紀末歐洲的優雅舞蹈與音樂形式，其核心特色為 3/4 拍節奏與明確的「強 - 弱 - 弱」律動，營造出旋轉與漂浮般的流動感。它由奧地利與德國的民間舞蹈發展而來，進入宮廷舞會後成為浪漫與社交自由的象徵；在音樂上以圓舞曲式旋律與流暢線條著稱，而在舞蹈表現上則以連續旋轉、滑行步伐與封閉舞姿為主要特徵。
