wunder beta🌀 The Particles That Make Everything
The tiny cast of particles and forces that build everything you see.
What you’ll learn
- Identify the matter particles of the Standard Model: quarks, leptons, and their three generations.Twelve matter particles, six quarks and six leptons arranged in three generations, build all tangible matter, with the first generation forming everything stable around us.
- Explain how bosons carry three of the four fundamental forces.Forces arise from matter particles exchanging bosons: the gluon carries the strong force, the photon electromagnetism, and the W and Z bosons the weak force, while gravity lies outside the model.
- Describe the Higgs field, its 2012 discovery, and the Standard Model's open questions.The Higgs field gives particles mass; its boson was found at CERN in 2012, completing the model, though gravity, dark matter, and other puzzles show a deeper theory must lie beyond.
Questions this course answers
The Standard Model sorts elementary particles into which broad groups?
The Standard Model includes matter particles (quarks and leptons), force-carrying particles (bosons), and the Higgs boson.
Which particles make up protons and neutrons?
Quarks make up protons and neutrons; for example, two up quarks and a down quark form a proton.
How many generations do the matter particles come in?
Both quarks and leptons are arranged in three generations, each heavier than the last, with the first generation making up stable everyday matter.
Which everyday lepton carries electric current in wires?
The electron is the familiar lepton that orbits atoms and carries electric current; muons and taus are heavier, short-lived cousins.
How are forces transmitted in the Standard Model?
Forces are carried by bosons that matter particles exchange; only a few bosons carry three of the four fundamental forces.
Which boson carries the strong force that holds quarks together?
The strong force is carried by the gluon, which binds quarks into protons and neutrons and holds atomic nuclei together.
