hey, in case you need more information, the course descriptions are:
MATH-210*/0.5 Rings and Fields 3L
Integers, polynomials, modular arithmetic, rings, ideals, homomorphisms, quotient rings, division algorithm, greatest common divisors, Euclidean domains, unique factorization, fields, finite fields.
vs.
PHYS-453*/0.5 Specialist Physics Laboratory 6P
To provide students in the SSP degree programs with experience in a range of advanced experiments and techniques. Four experiments are performed selected from, for example, pure and applied nuclear physics, Mössbauer spectroscopy, fluid mechanics, optics, magnetic resonance, quantum effects in the solid state, superconductivity, and superfluidity.
this is a tough choice, because although the lab is more of what a physicist especially in PP, like to be involved in, I'm also inclined to take a lighter course since this is somewhat an elective choice - and the lab course would apparently take 6 hours a weeks of in lab time vs 3 hours for abstract algebra
