Vzorec užití:
a quantum of [energy/charge/light]
When the atom falls to a lower energy level, it emits a single quantum of light.
Amikor az atom alacsonyabb energiaszintre kerül, egyetlen fénykvantumot bocsát ki.
In this experiment, each electron absorbs exactly one quantum of energy.
Ebben a kísérletben minden elektron pontosan egy energiakvantumot nyel el.
The theory treats radiation as made up of separate quanta rather than a continuous wave.
Učební příklady
The atom gives off one quantum of light.
Az atom egy fénykvantumot bocsát ki.
Each quantum of energy is very small.
Minden energiakvantum nagyon kicsi.
In this model, energy comes in tiny pieces called quanta, one quantum at a time.
Častá chyba:
Learners sometimes think 'quantum' means 'very large' because of the phrase 'a quantum leap'. In physics, a quantum is actually a very small, discrete unit, not a large amount.
Význam
smallest discrete unit in physics
Kolokace
quantum of energy
|quantum of action
|single quantum
|emit a quantum
|absorb a quantum
Synonyma
discrete unit (More general and less technical; does not specifically imply quantum physics.)
Antonyma
continuum (Describes something changing smoothly without separate units, opposite to discrete quanta.)
Témata

Definice
A very small, single unit of energy or another physical thing in quantum physics.
The smallest possible discrete amount of energy, or of another physical quantity, that can exist according to the rules of quantum physics.

Vzorec užití:
quantum [noun]
Quantum mechanics has changed our understanding of how particles behave.
A kvantummechanika megváltoztatta a részecskék viselkedéséről alkotott képünket.
She is doing her PhD in quantum information science.
Kvantuminformáció-tudományból doktorál.
Quantum computers use quantum bits to process information in new ways.
Učební příklady
He studies quantum physics at university.
Az egyetemen kvantumfizikát tanul.

A kvantumszámítógép másképp működik, mint egy hagyományos számítógép.
This is a basic idea in quantum theory.
Častá chyba:
Learners sometimes use 'quantum' by itself to mean 'a big change' in general situations. For that idea, English normally uses the full expression 'a quantum leap', not just 'a quantum'.
Význam
relating to quantum physics
Kolokace
quantum mechanics
|quantum physics
|quantum computer
|quantum theory
|quantum state
|quantum effect
Synonyma
subatomic (Often overlaps in talking about very small particles, but 'subatomic' does not always imply quantum theory specifically.)
Antonyma
classical (In physics, refers to non-quantum theories like Newtonian mechanics or classical electromagnetism.)
Témata
science
|physics
|technology
Definice
About quantum physics or quantum effects at a very small scale.
Relating to or based on quantum theory, especially the behavior of matter and energy at very small scales.

We still do not have the right quantum of data.
Még mindig nem áll rendelkezésünkre a megfelelő mennyiségű adat.
A small quantum of help made a big difference.
Častá chyba:
Learners may overuse this sense in everyday speech. In normal conversation, people usually say 'amount' or 'a lot of' instead of 'a quantum of'.
Význam
specific measurable amount
Kolokace
a quantum of evidence
|a quantum of work
|a quantum of comfort
|a quantum of proof
|sufficient quantum of
Synonyma
amount (More common and general; 'quantum' sounds more formal and technical.)
Antonyma
lack (Emphasizes the absence of an amount where a quantum or sufficient quantity would be expected.)
Témata

Definice
A certain amount of something, usually used in formal or academic English.
A particular, often specified or measurable, amount or quantity of something, especially in formal, academic, or technical writing.

the quantum of [damages/compensation]
The parties agreed on liability but not on the quantum of damages.
A felek a felelősség kérdésében megegyeztek, de a kártérítés összegében nem.
The judge reduced the quantum of compensation awarded to the claimant.
A bíró csökkentette a felperesnek megítélt kártérítés összegét.
There is an ongoing appeal concerning the quantum in this case.
Učební příklady

Az ügyvéd azzal érvelt, hogy a kártérítés összege túl alacsony.
They only fight about the quantum of compensation now.
Most már csak a kártérítés összegéről vitatkoznak.
The court must decide the quantum before the case can end.
Častá chyba:
Learners sometimes think 'quantum' in legal texts still refers to physics. In law, it simply means the amount of money to be paid, especially as damages or compensation.
Význam
amount of legal damages
Kolokace
quantum of damages
|quantum of compensation
|assess the quantum
|determine the quantum
|dispute over quantum
Synonyma
amount (General term; does not carry the specific legal sense of an assessed sum in a court case.)
Antonyma
liability (In legal language, liability is responsibility for harm, while quantum is the size of the payment; they are complementary rather than strict opposites but contrast different aspects of a case.)
Témata

|business
Definice
In legal English, the sum of money that someone must pay as damages or compensation.
In law, the amount of money that a court decides must be paid as damages or compensation.
