Multiple Truths
It won’t come out. I’ve tried everything. Hot water, scrubbing, soaking, the works. I can’t get it out. I’ve scalded my hands trying to wash it away. Red hands, red carpet, red clothes. Why can’t it just go away? I haven’t tried Oxyclean, but is that how Billy Mayes died? I don’t remember. People of our social standing did not keep Oxyclean in the house anyway. Better not risk it. If I could just go back, maybe it would be different.
I never realized how much he loved me. I just thought I was a convenient wife. You know – of good breeding? I never thought he really loved me. It’s not like he said it. Not once. Then again, how many people from our life were taught how to express love? Few, if any is what I’d bet my, well technically his money on… but he loved me? When did that happen?
The blood, that’s an easy fix to clothes – cold water, soak, repeat. Every little princess learns how to get the blood out when the help won’t. When daddy hurts his princess, or when mommy strikes you a little too hard. When the neighbor calls you a filthy whore, and promises to make you feel the same way. The guilt from him is what is irreversible. I can’t seem to shake this awful feeling. Why should I feel guilty? All I did was cheat. He was the one who killed himself over it. What did he go and do that for? I swear I didn’t know he loved me.
The sirens approach. How’d they find out? Who called them? Who was – Jake. Scared, weak little Jake. I wonder if that’s how he got rid of his guilt. Cheating with a housewife, and calling the cops when the husband dies. Pathetic. He has the physique that models his hobby of running six miles every day, maybe that was why I picked him. Still, I hope he never can outrun his guilt. I blame everything but myself… sort of. I blame his inability to love, but I know I made it impossible for him to tell me he loved me. It is impossible to love a monster, at least that’s what I thought. I start making up a story. From my fairy tale days in a ersatz castle on a cloud, I was quite experienced. I’ll recreate the truth because as for the real truth? That I loved him too? No one will believe it.

Failing Destiny - Viera
Failing Destiny
‘Step… scuff…step…scuff…’ This sound was not foreign to the limping twenty-something year old man. His shoes scuffed along the tile floor as he made his way closer and closer to his destination. Having recently thrown out his tea, the man’s hand felt empty, and he occupied it by squeezing one finger to his palm at a time, like playing an awkward, one-handed saxophone. What brought this man out of bed on a Saturday morning was a woman, but not just any woman. This woman controlled his fate.
Daniel was already a talented sculptor, having studied in France, Italy, and India before returning to America. He returned for the purpose of studying art at a university. This was his second semester back at his American University, and he had already had some business to attend to. When he was 17, Daniel was in car accident, leaving him with night terrors, three funerals to attend, and a permanent knee issue. So, why had Daniel hobbled his way up three flights of stairs without a cane, ignoring the elevator, just to wait in an office? This answer was no different than any of Daniel’s other answers – art. “Daniel Suzuki?”
Daniel’s thin frame had only just found the seat when his name had been called. “Follow me.” The secretary motioned, waiting impatiently for him to catch up with her. Everything about this woman was obnoxious and intrusive, from the smell of her Bubblicious gum, to the sight of her bright pink blouse. “You hurt your ankle or something?”
“I jumped off a roof when I was twelve trying to save a baby rabbit.” Daniel lied to the woman. She nodded and shaped her mouth to an ‘o’, as if this was an acceptable answer. “Down the hall and…?”
“To the left,” The secretary answered, pointing, “can’t miss it.”
“Great, thanks.” Daniel smiled, before adding, “You’re about as helpful as a onion flavored toothpaste.” Three knocks on the right door, and Daniel was welcomed inside and asked to sit down. The woman that he was here to meet was older, about fifty something in age, and smelled vaguely of peppermint.
“So…” Marie smiled warmly, “you’re failing.” Straight to the point. “However, it says here that if you switch your major, and your courses, you could be a top student.” Marie lowered her half moon glasses and looked down her nose at him. “Thoughts?”
Daniel had many thoughts for this woman. Most of which revolved around her place in Dante’s Inferno, or a piece of sandpaper and where she might be able to place it, but he voiced none of them. Standing up, and leaning on her desk, he smiled. “Marie,” He stopped, “May I call you Marie?” He did not wait for a response from her blank face, “Have you ever wanted something so bad, you could…” Pausing for emphasis, He placed a hand on her shoulder and licked his lips, “taste it?”
Marie gulped, nodded, and stammered, “W-w-well, sure. Hasn’t everybody?”
“And you’d do anything to get what you want, yes?” Daniel’s voice lowered to a husky whisper.
“Oh God yes.”
“Well, I’m good with my hands.”
“Uh-huh.” Marie closed her eyes.
“And I’ve seen things you could never imagine.”
“What?”
“I’ve seen the horrors of the world that you could never fathom.”
“Daniel, I think it’s best that you-“
“I’ve seen death. I’ve bloody well seen death!” Daniel’s voice raised in volume. “When I close my eyes and sculpt, I create death in my hands for the world to see, but you are going to sit here, and tell me that my future revolves around me putting some paint on a paper?!” In his art class, Daniel refused to do anything but sculpt, pose, and read art related literature (magazines, history, etc.), and for that, he was failing. “Shall I slap some paint on a piece of paper and hang it on your refrigerator? Would that make you all proud?”
“Mr. Suzuki!”
“Marie!” Daniel mimicked. “I will not sit here, and be told that because I believe that art is more than drawing something pretty, that I shall fail. Pass me.” Daniel nearly growled at the flustered woman.
“You’re not making your chances any better!”
“Did I ever really stand a chance?”
“When everybody comes in here, they have the same chances that you were-“
“Don’t lie to me. I deal with art, I don’t deal with lies. You want a piece of art so badly that is happy?”
“Do not raise your voice to me, young man. It is not that simple.”
Snatching the pen from the woman’s hair violently, she shrieked and jumped backwards into her bookshelf, as if she had been struck. A couple of Marie’s coworkers had barged in and started to try to subdue Daniel. “Stop!” Daniel yelled loudly. “Here’s my bag, check that if you want to.” Daniel kicked his bag to some office workers. “I think there’s a plastic fork in there… ooh, scary.” Daniel mocked them. “Give me 45 seconds before you attack me again.” Daniel requested, and with a deep breath, grabbed a napkin from Marie’s breakfast bagel and began.
In red ink, on a napkin was an image of three couples – one gay, one straight, and one lesbian couple. In neat script, Daniel wrote, ‘Give Love Equal Chances.’ Handing her the napkin, Daniel laughed. “There’s your happy drawing. I’m not quitting. I’m not failing, and I don’t draw. However, if you ever need directions around the Louvre, let me know, because I’ve got a showcase going up there in two months.” Without another word, Daniel grabbed his bag, winked at the secretary, who looked horrified, and left.

Sermon 5/11/08
Sermon:
One of my favorite passages of the bible is from the book of First Timothy, and it says “Don’t let anyone look down on you because you are young, but set an example for the believers in speech, in life, in love, in faith, and in purity”. The first time I had heard it was during a camp session in New York. There were only 5 campers, including myself, and two sherpas, and as we sat around a fire, the five of us were surprised by letters from camp counselors that we had had years ago. One of my previous counselors had written that I was never without hope, and that it would always find me, I just have to be willing to look for it. That thought alone has stuck with me during both difficult times and easy times; and it has yet to leave me in the dark.
That summer I hiked up the steepest mountain I had ever seen, and it was almost too difficult for me. About halfway up I started having trouble breathing and I felt like I had no muscles left in my body to continue. I sat down and tried to breathe steadily and a good friend of mine came over and said to me, “You can do this. You can do this because if you quit now, everything you just went through will be for nothing.” The other campers and my sherpa had tried to encourage me to go on, but their words did not hit me in quite the same way that my friend’s had. Thinking back on that now, I can not help but think about the book of Acts, where the people from so many different countries speaking different languages all heard the same words come out of one mouth and understood, breaking through the language barrier. It seems to strike a similarity for me because I suddenly understood all that the others were trying to tell me, I just needed to hear it out of one mouth.
Eventually, I did make it up to the top of the mountain and I am sure I was not able to take it all in at once. I was mystified at how literally breath-taking the view was, and how I could see so much by just being a couple miles up. At that point, I felt the closest to God that I had ever felt, and it allowed me to feel completely surrounded by him. I felt entirely safe and protected, despite the risk of falling off the edge and being in immediate danger. Also in the book of Acts, it says “You have made known to me the paths of life; you will fill me with joy in your presence.” (Acts 2:28)
Afterwards, I went back to the campsite, and a couple days later I was home. That feeling of being privvy to the knowledge that God is always around us that I had found on top of that mountain was unlike anything I had ever experienced, and it is a constant comfort to know that it is still there, whenever I feel completely lost or alone. I hope that each of you can go on to find wherever it is that you find that, and never go on to forget that God is still speaking.

Mr. Kostecki "Light and Mirrors Lab"
Light And Mirrors
Experimenters: Molly Lorenz, Eric Tuvell, and Leo Geggis
Purpose: To find through experimentation images, and to form them with mirrors.
Materials Used:
• Paper
• Eye charts (normal and reverse)
• Meterstick
• Mirror supports
• Pencil
• Protractor
• Ruler
• Small flat mirror
• T-pin
• Tape
• White Paper
Set Up Drawing:
Experimental Procedure: After the normal eye chart had been taped to the wall, I chose line 11 and stepped back to mark the reading line where I could still read it. The distance between the eye chart and the reading point was measured and recorded. Next, a flat mirror was secured to the wall at chest level and the back of the reverse eye chart was held to my chest, and I stepped back until is was barely visible. That spot was marked as the new spot and the distance between it and the mirror was measured. In the next section, after one flat mirror was standing up vertically, a piece of white paper was taped down onto the tabletop securely. Vertically, a pin was set in front of the mirror, on the white piece of paper. After getting down to eye level with the paper, an experimenter put their head to one side of the pin, closed one eye, and used a ruler to draw a line on the paper from the image of the pin to the opened eye. This line was labelled as the outgoing beam. Next, a line labelled as the incoming beam was drawn from the object to the mirror, connecting it with the outgoing beam. Then, a third line was drawn from the eye to the mirror at a 90º angle to the mirror. Then, the fourth line was drawn from the object to the mirror, parallel to the third line. The angle from the outgoing beam and the nearest perpendicular line was measured, along with the angle between the incoming beam and its nearest perpendicular line. From when an experimenter put their head to the side of the pin on was repeated twice more, a new experimenter each time and a new position.
Analysis:
A. Describe the image of the reverse eye chart you saw on the surface of the mirror. Compare it with the appearance of the normal eye chart.
-Compared to the normal eye chart, the reverse eye chart seemed smaller in the mirror.
B. What distance did you measure between the mirror and the reverse eye chart?
-I measured 1.545 m as the distance between the mirror and the reverse eye chart.
C. What distance did you measure between the starting point and the eye chart on the wall?
- I measured the distanced between the starting point and the normal eye chart as 2.545 m.
D. Compare your answers in B and C. What is the relationship between the distances?
-The normal eye chart’s measurement was 1 m larger then that of the reverse eye chart’s measurements.
E. Compare the two angles measure in step 13 for each position. What is the relationship between the angles?
-
F. In your notebook, draw the experimental setup as viewed from above. Include the lines and angles for each trial.

Mr. Kostecki "Pendulums and Spring Waves Lab"
Pendulums and Spring Waves
Experimenters: Molly Lorenz, Eric Tuvell, Leo Geggis
Purpose: To discover the influencing factors of a pendulum’s time period, and experiment with the natural motion of pendulums and waves.
Materials Used:
• 5 metal washers
• 1.00 m cord
• A long, loosely coiled spring
• Masking tape
• Meterstick
• Paper clip
• Protractor
• Stopwatch
• Support stand
Set Up Drawing:
Experimental Procedure: After the pendulum had been set up with a paperclip on one end of the 1 m cord, with .5 m hanging below the base, and a washer on the end of the paperclip, the washer was lifted to a 20º angle from its resting position. At the same time that the washer was released, the stopwatch was started, and was not stopped until the pendulum had completed ten full swings. This was done three times in order to be able to find the average time for one full swing. Next, the washer was lifted to a 15º angle from its resting position and released as the stopwatch was started. Again, the stopwatch was stopped after ten full swings; this was also done three times. Then the cord was shortened to .75 m, and the washer was again released from a 20º angle as the stopwatch started. The stopwatch was stopped after ten full swings a total of three times. Next, the cord was shortened to .15 m, as the washer was released from a 20º angle and the stopwatch was started. The stopwatch was stopped after ten full swings, this being done three times. In the next part of the experiment, a long, loosely coiled spring was held on the floor at both ends by two people, one at each end. One end of the spring was lifted to 30 cm and put back down on the floor very quickly. After this, in one fluid motion, one end of the spring was moved about 15 cm to the right and then 30 cm to the left. Finally, one end of the spring was quickly pushed forward before being pulled back to its original position.
Analysis:
A. How much time did it take for the pendulum to complete one full swing when it was raised to a 20º angle?
- When raised to a 20º angle, the time it took for the pendulum to compete one full swing on average was 1.43 s.
B. How much time did it take for the pendulum to complete one full swing when it was raised to a 15º angle?
- The time it took for the pendulum to swing on full swing on average when raised to a 15º angle was 1.41 s.
C. Compare the number of seconds of each swing at each position. Which initial angle required the longest time interval to complete one full swing?
- When the pendulum was raised to a 20º angle, it took longer for it to complete one full swing then when it was raised to a 15º angle.
D. How long did it take for each pendulum to complete one full swing?
-The .75 m pendulum’s full swing took 1.72 s. The .15 m pendulum’s full swing took .79 s.
E. Compare your observations for these pendulums with your observations for the .50 m pendulum.
- At .50 m and 20º, the average time for one full swing was 1.43 s. At .50 m and 15º, the average time for one full swing was 1.41 s. At .75 m and 20º, the average time for one full swing was 1.72 s. At .15 m and 20º, the average time for one full swing was .79 s. As you can see, the longest time was at .75 m and 20º, whereas the shortest time was at .15 m and 20º.
(F-H’s necessary trials were not done.)
I. What did you observe when you quickly lifted the spring and set it back down again?
- The amplitude of the wave travelled down the distance of the wave and then returned.
J. What did you observe when you quickly moved one end of the spring about 15 cm to the right and then 30 cm to the left?
- The wave on the right travelled to the other end before returning with the wave reflected on the left side.
K. What did you observe when you quickly pushed the spring forward and brought it back to its original place?
-The compression travelled down to the end of the spring before returning back to the original end.
Conclusion:
The experiments happened in accordance with our studies, behaving as expected. The pendulum with the shortest length had the smallest period time, whereas the opposite is true as well and the waves also followed our notes and preconceived notions.

- At .50 m and 20º, the average time for one full swing was 1.43 s. At .50 m and 15º, the average time for one full swing was 1.41 s. At .75 m and 20º, the average time for one full swing was 1.72 s. At .15 m and 20º, the average time for one full swing was .79 s. As you can see, the longest time was at .75 m and 20º, whereas the shortest time was at .15 m and 20º.
(F-H’s necessary trials were not done.)
I. What did you observe when you quickly lifted the spring and set it back down again?
- The amplitude of the wave travelled down the distance of the wave and then returned.
J. What did you observe when you quickly moved one end of the spring about 15 cm to the right and then 30 cm to the left?
- The wave on the right travelled to the other end before returning with the wave reflected on the left side.
K. What did you observe when you quickly pushed the spring forward and brought it back to its original place?
-The compression travelled down to the end of the spring before returning back to the original end.
Conclusion:
The experiments happened in accordance with our studies, behaving as expected. The pendulum with the shortest length had the smallest period time, whereas the opposite is true as well and the waves also followed our notes and preconceived notions.

The Ideal Gas Law
Experimenters: Eric Tuvell, Molly Lorenz
Main Purpose: Using the Ideal Gas Law, we should be able to understand the different relationships between pressure, temperature, volume, and how they work ideally at a molecular level.
3) T&V Materials Used:
Gas Law Apparatus Syringe
Air Chamber and Tubing
Short Pieces of Tygon Tubing
Computer Based Laboratory System
2 Large Insulated Containers
Hot Water
Ice
Pressure Sensor
Temperature Sensor
RealTime Physics Heat and Thermodynamics experiment configuration files
3) T&V Predictions:
Prediction 1-3: A low-friction syringe containing air is moved from a water bath at one temperature to one at a higher temperature. (The syringe is left long enough so that the air is in thermal equilibrium with the water baths.) How does the volume of the air change? What do you think will be the mathematical relationship between V and T with the pressure held constant?
We thought that the volume will increase, and that the relationship between volume and temperature will be linear.
3) T&V Experimental Procedure:
After connecting the flask to the pressure probe and to the syringe, we opened Measuring V and T (L05A2-3) on the computer, as both the temperature and pressure sensors were already connected to the computer interface. While some dimensions of the tubing were already given to us, others were not, so measuring with a piece of string, we arrived at our estimated volume of tubing at 8.5 cm3. Setting up Table 1.3 (see attached) with our volume of tubing, and the volume of the sensor being 0 cm3. The flask was submerged in the cup of warm water (approx. 343 K) when the graphing simultaneously began. The sensor was disconnected from the syringe after the pressure and temperature had stopped fluctuating. Then, the piston on the syringe was pulled out to 20 mL and the valve was closed off. After the pressure and temperature had once again, stopped changing, we kept the data point and entered the total volume. After that, every time ice was added to the cup of hot water, the syringe was adjusted so that is remained isobaric, and we kept data points and entered in the new total volume. We repeated that until we had 5 data points down to 3 cm3 as the volume of air in the syringe. Lastly, we used the fit routine to find the relationship between V and T and printed the graph.
3) T&V Analysis:
Question 1-5: What is the relationship between V and T? Is it proportional, linear, inversely proportional, or something else? Did this agree with your prediction?
The relationship between volume and temperature was proportional linear and it did agree with our prediction.
Question 1-6: Write down the relationship between the initial pressure and volume (ViTi) and the final pressure and volume (VfTf) for an isothermal process.
ViTi= 45.5 cm3, VfTf= 16.5 cm3 The initial is larger then the final.
Question 1-7: Are the relationships you found in the past three activities consistent with the ideal gas law? Explain based on your investigations of Boyle’s law, Gay-Lussac’s Law, and Charles’ Law.
The last three activities were consistent with the ideal gas law, PV=nRT. Boyle’s Law, Gay-Lussac’s Law, and Charles’ Law all coincide with one another for the Ideal Gas Law. If one of these laws were false, then they all would, by extension, be false as well.
Ideal Gas Law: PV=nRT
Boyle’s Law: P1V1=P2V2
Gay-Lussac’s Law: P1T2=P2T1
Charles’ Law: V1T2=V2T1
3) T&V Conclusion:
The conclusion was that Charles’ Law was true, stating that V1T2=V2T1. Additionally, the other gas laws were also proved correct.

Computer Based Laboratory System
Pressure Sensor
RealTime Physics Heat and Thermodynamics experiment configuration files
Piece of String
Scissors
1) P&V Predictions:
Prediction 1-1: As you compress the air in a syringe by pushing the piston slowly, what will happen to the pressure? What do you think will be the mathematical relationship between pressure P and volume V?
We thought that the pressure will increase, and the relationship between pressure and volume will be inversely proportional.
1) P&V Experimental Procedure:
When the end of an unsealed syringe was attached to the pressure sensor using the Tygon tubing, the piston was started at 20 mL. Next, the file Pressure vs. Volume (L05A2-1) was opened and we recorded that the volume of the sensor was 0 cm3 for Table 1-1 (see attached). Some dimensions of the tubing we were using were given to us, but we had to account for the rest- so, using a piece of string to bend like the tubing we measure the inside diameter to be .3 cm, the length of the tubing to be 58 cm, and therefore, the estimated volume of the tubing to be 4.1 cm3. These volumes were recorded in Table 1-1 as well. Then, we slowly pushed down on the piston, and when the pressure reading was stable, we kept a data point, we repeated that 4 times. We used the fit routine, finding a relationship between P and V, and lastly, printed the graph.

Question 1-1: What is the relationship between P and V? Is it proportional, linear, inversely proportional, or something else? Did this agree with your prediction?
The relationship between pressure and volume was inversely proportional and did agree with our prediction.
Question 1-2: Write down the relationship between the initial pressure and volume (PiVi) and the final pressure and volume (PfVf) for an isothermal process?
PiVi=19.665, PfVf=17.28 The initial is larger then the final.
