Document Summary

Too demanding: demanding on the individual and their values, has to be the best action, Equal responsibility for allowing or failing to prevent as for any positive actions because: value attaches to states of affairs, principle of impartiality. Attack on integrity: alienated from our feelings, alienated from actions. Consequence of jim s inaction is pedro s killing 20. Williams wants to say that each of us is specially responsible for what they do, but what. Pedro does is included in what jim does under utilitarianism. Others actions become part of our own under utilitarianism. Feelings not given much weight in until calculus. Williams: feelings may be an indication of right/wrong.

Reflection Question: What do you value?

I value vacations and playing video games. I put forward the idea these are valuable things to me. However, playing video games is only an instrumental value. In other words, young students play video games because they receive joy and satisfaction from playing video games. Do you agree?

Question 1: Is traveling the world (vacations abroad) desirable because it is instrumentally valuable, i.e., only valuable because it will help you achieve or acquire other things you desire? Is this because you think it is bad (unpleasant) in itself or just neutral (neither desirable nor undesirable)? Or is traveling the world also intrinsically valuable, i.e. valuable for its own sake? If so, why?

Question 2: Is playing video games (Xbox, Playstation, Nintendo Switch) desirable because it is instrumentally valuable, i.e., only valuable because it will help you achieve or acquire other things you desire? Is this because you think it is bad (unpleasant) in itself or just neutral (neither desirable nor undesirable)? Or is playing video games also intrinsically valuable, i.e. valuable for its own sake? If so, why?

A Particle in a box
In order to answer the following questions you will need toconsideran infinite potential
well of length L, in which a particle has been confined.

1. For principal quantum number n=7, write code to calculatethenormalization constant.
Then, plot the probability density function for this state (usingL= 10).
2. Using the properly normalized wave equation from Question1,write code to determine
the expectation values <x> and <x2> . Is <x>oneof the most probable positions? Explain
why.
3. Using the properly normalized wave equation from Question1,write code to determine
the expectation values <p> and <p2> . Show the valueyouobtain for <p2> is equal to
2mE7 (where E7 is the energy of the n = 7 level). Remember that pisa differential
operator so you will have to use the diff command.
4. The uncertainty of a quantum measurement is defined on page222,Equation 6.41 (3rd
edition SMM). Using this equation calculate the uncertainties oftheposition and
momentum of a particle in the n = 5 state. Compute the productofthese uncertainties and
compare this with the prediction of the Heisenberguncertaintyprinciple.
Quantum oscillator
5. Repeat calculations in the previous question for the groundstatewave function of the
quantum oscillator. Comment on the obtained result.

Since we have two electrons with individual spin angularmomentum vectors, we can have a total spin angular momentum vectordefined by,
S ' = S1 + S 2 , which is the sum of the spin angular momentumvectors of the two electrons. The properties
of the total spin angular momentum are analogous to those of theother types of angular momentum that we have studied. The familiarresults are the following for the magnitude and z component of thetotal spin angular momentum vector.

(d) Write the vector addition diagrams for this case of twoelectrons each with magnitude spin 1/2.
(e) Thus, write the possible values for sâ.

components of the total spin angular momentum.

We will now, in a qualitative manner, demonstrate the quantummechanical exchange force resulting from the Pauli ExclusionPrinciple in the form of the antisymmetric totaleigenfunctions.

(j)Byconsideringhowthespatialpartofthetotaleigenfunctionsbehaveswhenthetwoelectrons are in close proximity, argue that the parallel spin casecorresponds to an 2effective repulsive force,while the antiparallel spin case corresponds to an effectiveattractive force.
