Ultimate Cup Winners!
Semester champions McGovern and Cohen take home the grand prize! In a very
close matchup, they narrowly beat out the second-place winners Eshelman, White
and Mehta.
Who will win the Ultimate Cup Challenge?
It is for _you_ to decide. Please email me your vote sometime
before Sunday night. The winner will be revealed before you
take the final exam. I will also post the results up onto the
webpage. To make things interesting, you are allowed only one
vote, however you are not allowed to vote on your own project.
Here they are, in alphabetical order:

Cup of Recitation Week #6
Congratulations to Sajjan Mehta! Style and presentation were the keywords for
this victory. As you have probably realized, typing
in coordinates to hit the target (especially with air resistance) makes the game
much harder. Being able to visualize data (or coordinates in this case), is one of the
hallmarks of a good presentation.
Quantum Toys
Ever wanted to play around with Quantum Mechanics? Dr. Goldberg and I have coded up
a nice visual demonstration of the time-evolution of a
quantum harmonic oscillator. The command-line syntax is:
python QHO.py n1 n2 n3 n4
Where n1..n4 are the coefficients of the initial state (ie. [1 0 0 0] represents the ground state, while [1 0 1 0] represents a superposition of the ground state and the second excited state). The red and green lines represent the real and imaginary parts of psi, while the blue line is the observable |psi|**2. The dashed line is the kinetic energy curve. Note that a classical particle could only be found in the space where K > 0. The expected position at the given time is represented by a blue dot. For any superposition of states, notice anything characteristic about it's motion?

Cup of Recitation Week #5
Congratulations to Amanda White! It is hard to choose a single
winner when the end result is a graph, but White's submission was the best of
them all. When presenting a graph clarity it the name of the game. Adding more
information to a graph can leave your audience with less understanding if you
are not careful. Take a look at the
main code along with the attachments

Cup of Recitation Week #4
Congratulations to Andrew Eshelman! The previous weeks left me with
the agonizing decision of choosing a single winner. This week, it was was no
contest. The graded part of the assignment was fine (part A
and part B), well-commented, but no real
difference from the many other submissions.
However Eshelman extended the 1D linear chain to a 2D
triangular structure and its extension
to a 3D
pyramid!
Cup of Recitation Week #3
Congratulations to Sajjan Mehta! For an example of on how to produce clean
well-commented code look no further than the two submissions for
parts A and
part B. I cannot stress how important it is
to produce code that is clean and well-commented; this is for the benefit of others
and yourself!
He also went a step further than most and considered a
general N-body problem. Instead of simply considering a single massive body interacting
pair-wise with its surrounding neighbors, he considered all possible forces
in the system. Great work!
Cup of Recitation Week #2
Congratulations to Alexander Karagodov!
His submission was a great example
of 'adding new physics'. With the assigned problem completed he
went the extra distance by adding a coefficient of restitution (i.e.
a non-elastic collision) to his code. An honorable mention goes to Sajjan who
was narrowly beat out with the same general idea.
Homework #2 solutions have been posted in the sidebar.
As a reminder, office hours (Oct 23) will be today from 3PM-5PM in the computer lab.
Cup of Recitation Week #1
Congratulations Robert Kaylor! While the first assignment did not
leave much for creativity, Mr. Kaylor's assignment
was selected for its attention to detail and the clarity of the resulting graph. Great work!
HW #1 Comments
As with most of the homework assignments, I have created a
solution guide for you. Please review it
carefully and ask me if you have any questions. While I have given 10
points for every problem, each homework assignment will be given the
same weight when it comes to your final grade (breaking each problem into
10 points helps allot the partial credit). Now, for a few comments on the HW itself.
Please make sure that you understand what a dot product and magnitude is, these
concepts are essential to this class. While I am required to take off points
for incorrect units, I am going to take off points for the lack of
proper scientific notation and or significant digits. Please ask me or
look these concepts up, it looks silly when you write 1 / 7.0 = .1428571428571...
