Below is attached a lab report I recently submitted for my Classical Mechanics lab detailing how fluids affect the motion of oscillators. A spring-mass system was subjected to air, water, and a water-shampoo mixture, to see if the oscillations were affected, and if so, to find the damping ratio.

Morning
First lab was a Classical Mechanics alb where we worked on a cylinder rolling down a plank. We tried to pinpoint the angle at which the cylinder started to slip instead of just rolling. We did this for two cylinders. We then put a mass in static equilibrium and measured the various angles, lengths, and what have you.
Afternoon
In Thermodynamics lab, we found out that every Monday for the rest of the semester we will have to hand in a lab. We have piles of various lab procedures throughout the lab to look for labs to do, but I just finished out my Classical Mechanics lab in this time so I could hand it in.
Evening
Went to work from 4 to 8 PM, then came back home and played some Sonic and Sega All-Stars Racing (with Banjo-Kazooie). It is quite fun of a game.

Morning
Rose at 8 AM to another dull, dreary day. I cannot fathom why it has been raining so much, I do however know I want it to stop. Breakfast, then attended the first class of the day. After Classical Mechanics, where we studied potential energies and the like, I started to build my model rocket which in a few weeks we will be shooting off. Hopefully I can post a picture of it before shooting it off and maybe OF shooting it off.
Afternoon
Quantum was interesting and put what we learned in Mathematica Methods of Physics to use. Planetarium Techniques was cut short because we are just working on scripts for our next planetarium show. Since I had some free time, I worked some more on my rocket, and it is coming along fine and near completion, I think.
Evening
Attended colloquium, which was presented by an alumnus. A brief description copied from the college website is provided below:
Rest of the night was given to finishing up the rocket and writing a lab report for Classical Mechanics.

Katherine Pazamickas, Lycoming College 2009 alumnus and 2010 National Aeronautics and Space Administration (NASA) intern at Goddard Space Flight Center associated with NASA Pennsylvania Space Grant Consortium, will discuss, “Magnetospheric Research, Robotic Satellite Maintenance and NASA Academy." This gala event will take place in Lecture Hall C-303 of the Academic Center. Students, faculty, staff, and the public are invited.
Abstract: Katie Pazamickas will speak about her involvement with the NASA Academy this past summer at NASA's Goddard Space Flight Center. She will briefly introduce highlights of her own research involving sawtooth events in the earth’s magnetosphere, after which, she will focus on the Academy group project, “Investigating the Feasibility and Implementation of Orbit Robotic Satellite Maintenance.” Satellite lifetime typically ranges between 3 to 10 years, depending on the orbit and mission type. Considering the high costs involved in the manufacture and launch of such pieces of hardware, satellite servicing is an area that has generated substantial government and commercial attention in the past 25 years. This project explored a new robotic design to be ideally suited for satellite servicing, addressing the major problems satellites face as they degrade.
Rest of the night was given to finishing up the rocket and writing a lab report for Classical Mechanics.

Morning
As normal a morning as could be. Ate breakfast, surfed the net, then went to classical mechanics. Classical Mechanics is so much different from the first semester of college physics, Physics 225. It really is a whole nother level.
Afternoon
Homework due in Thermodynamics and in Quantum Mechanics. Both of the aforementioned classes were held outside. Quantum mechanics is still a mystery to me, while thermodynamics is getting pretty interesting.
Evening
Steve bought 100 proof Southern Comfort. Tasted it. It was quite thick and had noticeable flavour, somewhat sweet. Reminded me that I need to put up some beer reviews I have notes on somewhere. Stayed up until 2 AM for no real reason. Everyone was in the room talking for a while.

Morning
Finishing touches to the Thermodynamics lab number 2 were completed in the morning. Mostly analyzing the data followed by a terse conclusion. The lab can be viewed here: Lab 02 (.pdf)
In the first class of the day, Classical Mechanics, a homework set was due involving projectile motion and drag forces. I have noticed that most of the problems are not plug and chug, in fact I have not come across a problem that could be solved as such yet. Most problems need to be solved by deriving theorems and formulas from first principles. This gets tough sometimes, but I get the answer right most of the time.
Afternoon
Turned in a lab and some homework. All classes went as schedule. The first of the Planetarium Techniques mini-shows have started, I will be giving mine on Friday. It will be quite easy as long as I find my stars in the dome beforehand so that I know where to look. One of the stars I will be focusing on is in Perseus, so I do not think that one will be a problem.
Evening
Nap after work, then homework until 1 AM.

Ah, Friday morning. The start of a day where everyone is thinking about the end of the day and wouldn't care less if the hours of 9 AM to 5 PM were sucked into a black hole that only affected time. Anyway, my classes were for the most part fine. I found out that I got a 100 on my Classical Mechanics lab, which sort of surprised me. I was only informed via email, so I do not know if any corrections were made.
Afternoon
Finished off some homework involving entropy for Thermodynamics and attended my three classes. Nothing of note went on.
Evening
Work from 3:30 - 8 PM, where I started out in the basement and was then moved up to the hell hole that is the Tween/Teen section. Needless to say, the hours drag on as slow as they possibly could. The rest of the night was full of finishing off homework after browsing Netflix Instant Queue which had nothing on it.

Morning
Woke up at 7 AM, which has become the new norm for me. I worked on finishing touches to a lab report due for Classical Mechanics. At Classical Mechanics lab we worked on using Mathematica 7 to solve projectile motion problems with both linear drag resistance and quadratic drag resistance with differential equations. The output of Mathematica from this lab can be viewed here in PDF format: Lab
Afternoon
My afternoon consisted of working on various homework sets for Thermodynamics and Classical Mechanics. I do not have anything due for Quantum until next week. I then had Thermo lab but decided not to work on it then and will probably due it this weekend.
Evening
Relaxed and did homework.

Morning
Awoke at 7 AM to finish the Quantum Mechanics homework assigned two days before. Of course, the professor said it would be an elementary assignment, but it did give us some challenge. The problem was to find <x>, <p>, <p^2>, <E> of the Psi function:
Took some work but most answers came out to around the cube of the Sine function in some form.
Afternoon
Went to Quantum Mechanics, Planetarium Techniques, and Thermodynamics (in that order) and all classes went as one would come to expect. Nothing was really out of the ordinary, and most of the math seems somewhat manageable as opposed to the past few days where the most fundamental of the quantum theories were derived and physically explained (to the extent that was possible).
Colloquium was quite good, if not almost completely over my head. The speaker, Dr. Rudeger (Derek) Wilke, talked about his work at the Materials Research Institute at Penn State University. The topic was how he is using peizoelectric materials to correct the lenses on an upcoming X-Ray observatory satellite. Here is the description from the Lycoming College website:
Evening
Took a nap, missed dinner, and played some Mass Effect. I will be typing up a lab report tonight for Classical Mechanics and I think I have a Thermodynamics homework due tomorrow. Quite beat and cannot wait for the weekend to catch up on reading and recharge the batteries.

Post-Doctoral Scholar and Visiting Scientist in the Materials Research Laboratory at The Pennsylvania State University, will discuss, “Piezoelectric Lead, Zirconium, Titanium (PZT) Films on Glass Substrates for Gen-X Imaging Systems.” This gala event will take place in the Academic Center Lecture Hall C-303. Students, faculty, staff, and the public are invited.
Abstract: Gen-X is a next generation spaced based x-ray telescope that hopes to study distant, faint objects such as the formation of black holes, distant galaxies, and the early evolution of the universe. They key to achieving the desired goal of 0.1 arcsecond resolution is the implementation of an adaptive optics system that allows on flight corrections of structural or figure errors in the mirror and minor adjustments to alignment. The optics for the telescope consist of "bi-morph" mirrors on flexible glass substrates. These mirrors consist of an iridium/chromium (Ir/Cr) reflective surface on the front side and a piezoelectric Pb(Zr,Ti)O3 (PZT) thin film on the back side. With an active area of ~10,000 m2, developing a scalable approach to depositing PZT of sufficient quality to achieve the necessary actuation presents several processing challenges. The glass chosen for the telescope slumps above 560 oC, far lower than the 700 oC typically used to crystallize PZT films. Additionally, the stresses induced in thin film deposition can significantly warp the substrates due to their flexible nature, potentially introducing more figure errors in the mirror than can be corrected by piezoelectric film. In this talk I will review the fundamentals of piezoelectricity and how piezoelectric films can be used in adaptive optics systems, as well as discussing the progress made to date.It was interesting in I am quite intrigued by the electromagnetic properties involved in the process.
