VIEW THIS PAGE Fog and mist are essentially the same thing — cloud banks made of suspended water droplets — so why do we have different words for them? The only difference is the density, but the distinction is highly subjective. In aeronautical terms, if a pilot cannot see further than 1km, it is defined as fog. For motorists, visibility must fall below 200m to be classed as fog, otherwise it is known as mist.
霧和靄實質上是一樣的東西──懸浮的微小水滴所形成的雲層,那為什麼會有不同的名稱呢?它們唯一的差別在於密度,但其區分法則非常主觀。在航空用詞中,若飛行員看不見一公里以外的景象,就稱作霧。對開車族來說,能見度一定要低於兩百公尺才會被歸類為霧,除此之外的都稱為靄。
Whatever you choose to call it, fog forms when air rapidly cools, causing the water vapor to condense. Fog often forms in coastal areas when warm air moves in from the sea. The temperature of the land is colder than the sea, which causes the air to cool.

In today’s experiment you will recreate this scenario to make your very own fog.
What you will need: some hot water, two bottles and two packs of ice cubes.
無論怎麼稱呼,霧是由於空氣急速冷卻,造成水汽凝結而形成。霧通常出現在沿海地區,海上的暖空氣吹向陸地,陸地的氣溫比海面氣溫低,空氣因此冷卻。
今天的實驗中,你將重建上述情景,做出屬於你自己的霧氣。
實驗所需:一些熱水、兩個瓶子和兩包冰塊。
METHODOLOGY方法
Step 1: Fill one bottle with hot water. Tap water will suffice — it does not need to be boiling. Let the bottle stand for ten minutes to heat it up.
Step 2: Fill the other bottle with cold water and allow it to stand.
Step 3: Empty 80 percent of the water out of both of the bottles, so that just a little bit remains at the bottom.
Step 4: Turn both bottles on their side, then take the packs of ice cubes and press them on the bottles. You should notice fog appearing inside the bottle that contained hot water. Hold the ice cubes in place until the bottle is full of fog. No fog will appear in the cold water bottle no matter how long you hold the ice.
步驟一:將一個瓶子裝滿熱水,自來水的熱水即可──不需要用到煮沸的開水。把這個瓶子靜置十分鐘,讓瓶身升溫。
步驟二:將另一個瓶子裝滿冷水後靜置。
步驟三:將兩個瓶子內的水倒出八成,只留下一點水在瓶底。
步驟四:將兩個瓶子平放,然後把兩包冰塊分別壓在兩個瓶子上。你會發現裝熱水的瓶子中產生了霧氣。保持冰塊的位置,直到瓶中充滿霧氣。無論你用冰塊壓多久,裝冷水的瓶子裡都不會產生霧氣。
WHAT HAPPENED? 實驗結果
This simple experiment recreated the conditions that occur naturally to form fog. The air inside the hot water bottle cools quickly causing condensation. The air in the other bottle is already cold, so condensation doesn’t form.

這個簡單的實驗重新建構了大自然形成霧氣的環境。熱水瓶中的空氣急速冷卻而凝結;另一個瓶子中的空氣本來就是冷的,所以不會有水汽凝結。

It’s no secret that Japanese people have a deep affection for noodles. Like in the rest of East Asia, noodles are an important staple food, second only to rice. Japanese people have enjoyed noodles for over 1,000 years. The first noodles came from China and were introduced around 800 CE. As time passed, noodles in Japan not only became widespread but also developed some unique Japanese characteristics. The three most popular types of noodles in Japan are ramen, soba, and udon. Ramen, typically made from wheat flour, is usually thin and firm. The dough is kneaded and left to
Rice is an essential ingredient in Taiwanese cuisine. Many foods are made of rice, adding more variety to our cooking, such as rice cake, or “gui.” Wagui is made by steaming rice flour batter in a bowl. The term “gui” refers to a type of food made from rice, while “wa” refers to a bowl. The pronunciation of “gui” in Taiwanese Hokkien is similar to the word for “nobility” in Chinese, so it is common for people to prepare various types of gui, including wagui, as offerings to the gods or ancestors,. 米是台灣重要的主食,用米製成的食品十分多元,豐富我們的飲食,如米做成的「粿」。粿的意思是米做成的糕點,碗粿是將在來米漿倒入碗中蒸熟,因而得名。粿因為音同「貴」,因此碗粿等粿食常用作供品祭拜神明和祖先。 nobility (n.) 高貴,高尚;貴族 offering (n.) 供品 While Taiwan may not be
On Tuesday last week, the flame for this summer’s Paris Olympics was lit at the birthplace of the ancient Olympic Games in southern Greece in a meticulously choreographed ceremony. It will then be carried through Greece for more than 5,000km before being handed over to French organizers at the Athens venue used for the first modern Olympics in 1896. The pageantry at Olympia has been an essential part of every Olympics for nearly 90 years since the Games in Berlin. It’s meant to provide an ineluctable link between the modern event and the ancient Greek original on which it was initially modelled. Once
Continued from yesterday(延續自昨日) https://www.taipeitimes.com/News/lang As with many aspects of Japanese culture, there is etiquette to follow when you enjoy noodles. To fully experience noodles like a local on your next visit to Japan, consider these simple guidelines. First, be careful where you put your chopsticks. Don’t leave them sticking up in the broth or set them at the side of the bowl. When you have finished eating or if you’re taking a break, place them on the chopstick rest next to the bowl. Also, it is impolite to wave chopsticks around or bring them above mouth-level. Second, don’t take too
