Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the related fields?Crucial in particle physics, condensed matter physics, statistical mechanics, and cosmology
2. Why does a pencil fall when balanced on its tip?The pencil is in an unstable balance; any tiny push makes it fall, breaking the rotational symmetry and settling into a stable, uneven position.
3. How does spontaneous symmetry breaking give particles mass?In the Higgs mechanism, a field gets a non‑zero value that breaks symmetry, and this gives mass to particles like quarks and leptons.

Vacuum Expectation Value (VEV): The average value of a field in its lowest energy state, often non-zero in SSB.
Goldstone Boson: A massless particle predicted by the Goldstone theorem for each spontaneously broken continuous symmetry.
Higgs Mechanism: A process where gauge bosons acquire mass through spontaneous symmetry breaking involving the Higgs field.
Electroweak Symmetry Breaking: The process in the early universe where the electromagnetic and weak forces separated due to SSB.
