快速理解

What does "Quantum" mean?What are 2-3 core uses of "Quantum"?

「quantum」一詞主要源於物理學,指能量或物質的最小單位,現已延伸至計算、金融等領域,表示離散、不連續的量或一次巨大的飛躍。

  1. 1

    物理學核心概念

    EN: The smallest discrete unit of energy or matter in physics.

    翻譯: 物理學中能量或物質的最小離散單位。

  2. 2

    量子力學與計算

    EN: Relating to quantum mechanics or quantum computing, which uses quantum bits (qubits).

    翻譯: 與量子力學或量子計算相關,後者使用量子位元(qubit)進行運算。

  3. 3

    特定數量或份額

    EN: A required or allowed amount, especially in financial or legal contexts.

    翻譯: 特指所需或允許的數量或份額,常見於金融或法律情境。

  4. 4

    比喻:巨大飛躍

    EN: A sudden, large, or significant increase or change.

    翻譯: 比喻突然、巨大或意義重大的增長或變化。

小提醒:注意「quantum leap」在物理學中指量子躍遷(微小的能量變化),但在日常用語中常比喻「巨大的進步」,兩者意義看似相反,需根據上下文判斷。

Aaron O'Connell: Making sense of a visible quantum object

TED

You can be logical and intuitive, And so I consider myself one of these people, along with most of the other experimental quantum physicists, who need a good deal of logic to string together these complex ideas, But at the same time, we need a good deal of intuition to actually make the experiments work.

用法說明

How is "Quantum" different from similar structures?What usage mistakes are common with "Quantum"?

quantum 與 a quantum of

  • quantum 作為名詞,通常指一個不可分割的、離散的「量」或「單位」,尤其在物理學中特指「量子」。它本身是一個可數名詞。
  • a quantum of 這個片語則用於指「特定事物的最小量或基本單位」,常用於較正式的語境,有時帶有「微量」或「最基本份額」的含義。
  • 在非專業語境中,quantum 有時會與 quantity(數量)混淆。Quantity 泛指一般的「量」,可以是任何大小;而 quantum 強調的是「特定的、不可再分的單位量」。

對比範例: EN: The theory explains the behavior of a single quantum of light, called a photon. 翻譯: 這個理論解釋了單一光量子(稱為光子)的行為。

EN:He did not show a quantum of evidence to support his claim.

翻譯:他沒有拿出絲毫證據來支持他的主張。

總結建議

在專業物理領域使用單數 quantum,而在表示「極小量」或「基本單位」的抽象概念時,使用片語 a quantum of

易混淆對比

What is the difference between "Quantum" and similar words?How to choose "Quantum" vs alternatives?

quantum vs particle

「quantum」指能量或物理量的最小單位,強調其不可分割的離散性;「particle」則泛指任何微小的物質單位,如原子、電子或分子,範圍較廣。

quantum vs photon

「quantum」是抽象概念,指任何物理量的最小單位;「photon」則是光量子,是「quantum」概念的一個具體實例,專指光的能量單位。

quantum vs quantized

「quantum」是名詞,指離散的最小單位本身;「quantized」是形容詞,描述某物理量被限制在這些離散數值(量子)的狀態。

口語用法

引述

在口語中,當引述或提及一個複雜、新穎或帶有特定定義的概念時,會使用「quantum」。 EN: He kept talking about the "quantum" of the agreement, but I had no idea what he meant. 翻譯: 他一直在講合約的「quantum」,但我完全不懂他的意思。

EN:In the meeting, someone mentioned a "quantum leap" in technology, and everyone just nodded along.

翻譯:會議中有人提到科技的「quantum leap」,大家就只是跟著點頭。

語氣強調

用於強調變化或差異的巨大與根本性,常帶有誇張或比喻的語氣。 EN: This new policy represents a quantum shift in how we operate. 翻譯: 這項新政策代表了我們運作方式上的 quantum 級轉變。

EN:The difference between the two designs isn't just small; it's quantum!

翻譯:這兩個設計的差別不只是微小,根本是 quantum 級的!

停頓填充

有時說話者會在思考如何描述巨大變化或抽象概念時,將「quantum」作為一個填充詞,以爭取思考時間或製造懸念。 EN: Our approach needs a... quantum... reimagining to succeed. 翻譯: 我們的方法需要一個… quantum… 重新構思才能成功。

EN:The impact was, well, quantum, you know? It changed everything.

翻譯:那個影響,嗯,可以說是 quantum 級的,你懂嗎?它改變了一切。

正式寫作注意:在學術、法律或正式商業文件中,應避免將「quantum」用於上述口語的誇張或填充用途。在這些場合,「quantum」應嚴格用於其專業定義(如物理學的量子,或法律中的「quantum of damages」損害賠償額),以確保精確性。

What are common mistakes with "Quantum"?Which "Quantum" sentences look correct but are wrong?

×The quantum of the particles are very small.

The quantum of the particles is very small.

"Quantum" 作為主詞時,即使後面接 "of + 複數名詞",動詞仍須與單數主詞 "quantum" 一致。

×He made a quantum improvement in his skills.

He made a quantum leap in his skills.

在英文中,表示巨大或飛躍性的進步,固定搭配為 "quantum leap" 或 "quantum jump",而非 "quantum improvement"。

×I need to buy a quantum of milk from the store.

I need to buy a certain amount of milk from the store.

"Quantum" 在現代英文中,主要用於物理學或正式、技術性語境,表示不可分割的最小單位或特定量。在日常購物等一般情境中,使用 "amount", "quantity" 或 "portion" 更為自然。

×This is a quantum theory.

This is quantum theory. / This is quantum mechanics.

當 "quantum" 作為學科名稱的一部分時,通常不加冠詞 "a"。"Quantum theory" 或 "quantum mechanics" 是作為專有名詞般的整體概念。若指特定的一種理論,則可能用 "a quantum theory",但極少見。

×The quanta of light is called photons.

The quanta of light are called photons.

"Quanta" 是 "quantum" 的複數形。當主詞是複數名詞 "quanta" 時,動詞必須使用複數形式。
