Quantum
Explain superposition, particles, and thermodynamics with precision — and say it all out loud.
The formal terms map cleanly — la mecánica cuántica, la superposición cuántica, el entrelazamiento cuántico, el principio de incertidumbre — but what marks you as fluent is knowing how physicists actually shorten them in the room: la cuántica for the whole field, el Heisenberg as an affectionate shortcut for the uncertainty principle, la lambda at the blackboard instead of la longitud de onda. Pop-science talk has its own register too — la partícula de Dios for el bosón de Higgs, partir el átomo for la fisión nuclear. The precision habit that keeps you credible: always specify the framework, clásico or cuántico.
Below: the terms lesson by lesson, the classroom shorthand students really use — and a way to rehearse explaining these concepts out loud, no worksheets involved.
The warm-up pack
The sentences a physicist reaches for mid-explanation — not a formula sheet.
01 · The idea that breaks intuition
La superposición cuántica explica por qué una partícula puede estar en dos estados a la vez.
Quantum superposition explains why a particle can be in two states at once.
This is the one sentence that actually earns the confused look — say it slowly and let it land.
02 · The connection with no distance limit
El entrelazamiento cuántico conecta dos partículas sin importar la distancia.
Quantum entanglement links two particles no matter the distance.
The word entrelazamiento does the work here — "tangled together" is a more honest image than "spooky action."
03 · Heisenberg without the name-drop
El principio de incertidumbre dice que no puedes conocer posición y velocidad a la vez.
The uncertainty principle says you can't know position and velocity at the same time.
You don't need to say "Heisenberg" to sound credible — stating the principle plainly is more convincing.
04 · The particle everyone's heard of
El bosón de Higgs le da masa a las partículas.
The Higgs boson gives particles mass. (Colloquially, la partícula de Dios — "the God particle")
One sentence, and you can explain to a non-physicist why this discovery mattered.
05 · The machine behind the theory
El acelerador de partículas del CERN hizo el descubrimiento.
The CERN particle accelerator made the discovery.
Grounding an abstract idea in an actual place and machine is what makes a scientific claim sound credible out loud.
06 · The force that holds the nucleus together
La fuerza nuclear fuerte mantiene unido el núcleo del átomo.
The strong nuclear force holds the atomic nucleus together.
Fuerte here isn't an adjective for emphasis — it's literally the name of the force, distinct from the "weak" one.
07 · The one-word reaction
¡Pura entropía!
Pure entropy!
What Spanish speakers actually say about a messy room or a chaotic meeting — the physics term doubles as an everyday complaint.
08 · What a material actually does
La conductividad térmica del metal es alta.
The metal's thermal conductivity is high.
This is the difference between "it feels hot" and being able to say why, precisely.
09 · Why light has color
La longitud de onda determina el color de la luz.
Wavelength determines the color of light.
One clean cause-and-effect sentence that explains something people assume is complicated.
10 · From radio to gamma
El espectro electromagnético va desde la radio hasta los rayos gamma.
The electromagnetic spectrum goes from radio waves to gamma rays.
Naming both ends of the spectrum in one breath is what makes the concept feel complete, not half-explained.
11 · What powers the sun
La fusión nuclear es la reacción que alimenta al sol.
Nuclear fusion is the reaction that powers the sun.
The clean, sayable version of a concept people usually only meet in a diagram.

Olivia
Your vocabulary teacher for this pack
There's nothing to memorize in isolation here — in the Quantum lessons you learn these terms by talking, and Olivia puts you in the seminar seat: explain la superposición cuántica and el entrelazamiento to a room of graduate students, with analogies precise enough to survive their questions. Describe the partículas subatómicas of the Standard Model for a general audience. Walk an engineering review through la termodinámica and la resistencia de materiales. Out loud, in Spanish, until the vocabulary stops being translation and starts being thought.
Blank mid-sentence and nothing bad happens — she waits. That's the practice, without unnecessary judgement.
Finish the 6 lessons and Quantum is yours — earned, not given.

Quick answers
El entrelazamiento cuántico. In conversation, students often just use the adjective: particles are entrelazados. And among physicists the whole field is simply la cuántica.
Formally el principio de incertidumbre — but across Latin America you'll hear the affectionate shortcut el Heisenberg. The wave function gets the same treatment: at the blackboard it's just la psi.
El bosón de Higgs — popularly la partícula de Dios in Mexican and Argentine science communication — and el acelerador de partículas, though people usually just say el LHC when they mean CERN's.
La termodinámica — la termo among students — plus la entropía, la conductividad térmica, and la aleación (alloy). Entropía even works as everyday metaphor: puro caos, pura entropía.
In Latin America los quarks is pronounced /kwarks/, not /kjuarks/. Similarly, los neutrinos almost always shows up in the plural — the technical singular is rare in speech.
