Janet Echelman: Taking imagination seriously
TED
“Historic Philadelphia City Hall, its plaza- I felt needed a material for sculpture that was lighter than netting, So we experimented with tiny atomized water particles to create a dry mist that is shaped by the wind and, in testing, discovered that it can be shaped by people, who can interact and move through it without getting wet.”

用法說明
How is "Particles" different from similar structures?What usage mistakes are common with "Particles"?
particles 與 particle
- particles 是名詞 particle 的複數形式，指微小的顆粒或物理學中的粒子。
- particle 作為單數名詞，除了指單一顆粒，也可指語法中的「小品詞」（如介系詞、連接詞等）或表示極少量的「一點點」。
- 使用時需根據上下文判斷是指可數的「多個顆粒」還是不可數的「微量」。
- 在科學或正式語境中，複數形式 particles 更為常見。 EN: Dust particles floated in the beam of sunlight. 翻譯: 塵埃顆粒在陽光光束中漂浮。
EN:There is not a particle of truth in his story.
翻譯:他的故事裡沒有一點真實性。
總結建議
討論物理物質或科學概念時通常使用複數形式 particles，而表示極小量或語法術語時則用單數 particle。
易混淆對比
What is the difference between "Particles" and similar words?How to choose "Particles" vs alternatives?
particles vs atoms
「particles」泛指構成物質的基本微小單元，範圍較廣；「atoms」則特指化學元素中保持其性質的最小單位，是粒子的一種。
particles vs molecules
「particles」是微小物質單元的統稱；「molecules」則是由兩個或多個原子透過化學鍵結合而成的特定粒子。
particles vs grains
「particles」在科學上指微小的物質單元，概念抽象；「grains」通常指肉眼或顯微鏡下可見的固體小顆粒，更具體且常與沙、米、粉末等聯想。

EN:She was talking about particles and waves, and my eyes just glazed over.
翻譯:她當時在講粒子和波，我聽得頭昏眼花。
語氣強調
與具體的「灰塵」或「碎屑」連用時，常用來強調數量極少或微不足道。 EN: There wasn't a single dust particle left on the shelf after she cleaned. 翻譯: 她打掃完後，架子上連一點灰塵粒子都不剩。
EN:He analyzed every tiny particle of evidence in the case.
翻譯:他分析了這案子裡每一丁點微小的證據粒子。
停頓填充

EN:It's made up of, you know, tiny particles that we can't even see.
翻譯:它是由，你知道的，那些我們甚至看不見的微小粒子組成的。
正式寫作注意：在學術或正式寫作中，應避免將 "particles" 用作模糊的填充詞。需明確指出所指的粒子類型（如「基本粒子」、「塵埃粒子」、「懸浮粒子」），並提供精確的定義或上下文，以確保科學嚴謹性。

常見錯誤
What are common mistakes with "Particles"?Which "Particles" sentences look correct but are wrong?
×There are many particles in the air.
✓There are many particles in the air.
The sentence is grammatically correct. The common mistake is thinking 'particles' is uncountable. 'Particle' is a countable noun. The confusion arises because particles are often discussed as a collective mass, but grammatically, we use 'many particles' (countable plural) not 'much particle' (uncountable).
×I found a particle of glass on the floor.
✓I found a piece/shard of glass on the floor.
'Particle' is typically used for very small, often microscopic, pieces of matter (dust, atoms, etc.). For visible fragments of solid materials like glass, wood, or plastic, use 'piece', 'bit', or more specific words like 'shard' (for glass).
×In 'look up', 'up' is a preposition.
✓In the phrasal verb 'look up', 'up' is a particle.
Learners often confuse particles in phrasal verbs with prepositions. A key difference is that a particle can often be separated from the verb by an object (e.g., 'look the word up'), while a preposition cannot. The term 'particle' here refers to its grammatical function, not its physical meaning.
×This particles is too small to see.
✓This particle is too small to see. / These particles are too small to see.
Mismatch in subject-verb agreement. 'Particle' is singular, 'particles' is plural. The determiner ('this/that' vs 'these/those') must also agree in number.
×The particle of the sentence is 'to'.
✓The function word/grammatical particle in the sentence is 'to'.
In everyday language, 'particle' usually means a tiny piece of matter. Using it to mean 'grammatical particle' without context can be confusing. In linguistics, specify 'grammatical particle' or 'function word' for clarity.
