At the end of the Experimental Physics unit you should:
1) have learned how to keep a lab notebook
2) be able to combine errors in individual measurements
3) be able to fit a straight line to experimental data using leastsquares methods & hence obtain the gradient, yaxis intercept & their uncertainties

5) be familiar with the gaseous, liquid & solid phases of matter.
6) appreciate the universality of the MaxwellBoltzmann distribution for systems in thermal equilibrium
7) understand how quantities such as latent heat, critical temperature, surface tension, compressibility, elasticity & thermal expansion can be related to the parameters of the inter atomic/molecular potential
8) understand the zeroth & first laws of thermodynamics & the concepts of internal energy, heat & work
9) understand the concept of electric field, Gauss's Law, and potential associated with charges and perform calculations in simple gemoetries.
10) understand capacitance in simple geometries, effect of polar dielectrics and RC circuits.
11) understand the concept of magnetic fields and forces of moving charges and currents,
12)understrand the relation between current and magnetic field inclduing BioSavert and Ampere's Laws and perform calcualtions for simple geometries.
13) understand the concept of induction including Faraday and Lenz's Law and perform cauclations in simple geometries.
14) state Maxwell's Laws in inegral form and explain their relations to laws of electromagnetism.
15) qualitatively describe the magnetic properties of materials and the physical basis behind them.
16) be familiar with the failures of classical physics & how they relate to the early motivation for quantum theory
17) be able to state and appreciate the consequences of the key paradigmshifting notions of early quantum theory such as the deBroglie Hypothesis & the Heisenberg Uncertainty Principle
18) be able to discuss the early models of atomic structure & their relation to optical spectra
19) be able to write down the timedependent &  independent Schrodinger wave eqn & state why the latter has the structure of an eigenvalue eqn
20) be able to apply formal wave mechanics (through the Schrodinger eqn) to a range of fundamental problems concerning scattering & bound states.
