demonstrate an understanding of the basic concepts of Einstein’s special theory of relativity and of the development of models of matter, based on classical and early quantum mechanics, that involve an interface between matter and energy;

interpret data to support scientific models of matter, and conduct thought experiments as a way of exploring abstract scientific ideas;

describe how the introduction of new conceptual models and theories can influence and change scientific thought and lead to the development of new technologies.

describe the principal forms of nuclear decay and compare the properties of alpha particles, beta particles, and gamma rays in terms of mass, charge, speed, penetrating power, and ionizing ability;

describe the photoelectric effect in terms of the quantum energy concept, and outline the experimental evidence that supports a particle model of light;

describe and explain in qualitative terms the Bohr model of the (hydrogen) atom as a synthesis of classical and early quantum mechanics;

state Einstein’s two postulates for the special theory of relativity and describe related thought experiments (e.g., describe Einstein’s thought experiments relating to the constancy of the speed of light in all inertial frames of reference, time dilation, and length contraction);

apply quantitatively the laws of conservation of mass and energy, using Einstein’s mass-energy equivalence;

describe the Standard Model of elementary particles in terms of the characteristic properties of quarks, leptons, and bosons, and identify the quarks that form familiar particles such as the proton and neutron.
