Save SBPL!


Just today I visited my library's website to renew some materials and I saw a post about Save My Library. I read on and I learned that the governor of my state is planning a 4.5 million dollar cut for library funding. This of course has ramifications for my town, but our library is one of the more fortunate ones. Other libraries barely have an adaquate supply of books or resources. If you are a resident of New Jersey, please help.

Lit. Poems

In my literature class, I am given a project to write two poems based upon a setting, character, or theme of the novel The Book Thief. Out of the three poem types, I selected the Diamante Poem, and the Character poem.
This is the Diamante:

"The Owner of the Words"

Words
Colorful persuasive
Changing empowering frightening
Bellicose benign ambitious revered
Orchestrating ruling aspiring
Articulate Inventive
Speaker

This poem is the character poem:

"The Life of Death"

Death
Thoughtful, and Frightful
Who loves observing the world for colorful distractions
Who feels intrigued about Liesel Meminger's life
Who needs to collect souls during a time of war
Who shares his thoughts, words, and life
Who fears humans
Who'd like to see how people view death
Who dreams of a day off
Who ends up returning The Book Thief back to Liesel Meminger


So these are the two poems I wrote. If you have not yet read The Book Thief then please do. The intriguing words, paragraphs, and pages are carried to you by Death itself. The point of view is unique, this story is told from the German side of World War Two. If you have already read this excellent novel, please comment on whether these poems are relevant.

Magnatized Subatomicly


As a vacuum draws the air out of a tube, physicist Tim Gay prepares to smash polarized electrons into select molecules at the end of the tube. A Bayard-Alpert Gauge monitors the progress of the vacuum. Tim Gay studies polarized elections, which are electrons spinning in the same direction, at Nebraska-Lincoln University. In Gay's words, he explains it like this,

"The electrons have to move down the tube and hit a target without bumping into air molecules. Pumping out the air gives electrons a good shot at the target."

Gay studies polarized, or magnetized electrons have many uses. Uses such as improving computers and electronics to more energy efficient light bulbs to answering some of life's fundamental questions. Gay, with funding from the National Science Foundation, uses the magnetized electrons to answer some intriguing questions. Questions such as why DNA twists clockwise.

Naturaly, electrons spin is arbitrary directions, canceling out the magnetic energy. This is why most materials are not magnetic. Making the elections spin in the same direction is time consuming. Gay aims to make the process simple, and easy-to-use. A good source of polarized electrons provide new tools for industry and research. During the process of developing this method, the scientist has trained at least 85 undergraduates in his lab.

"I really view the mission of these experiments as half physics and half training tomorrow's high-tech workforce," Gay said.

Turn It Into Rock


The green house effect is a very important factor of life. The carbon dioxide absorbs the infrared light reflected from the ground. Other gases such as water vapor, methane, nitrous oxide, and ozone join to help the green house effect. This delicate balance has been maintained up until the industrial revolution. During this period humans begin burning fossil fuel to satisfy their luxuries. This is when the green house effect will ultimately doom the earth. Humans do not want to surrender their luxuries, so they find ways to eliminate the carbon dioxide by-products.

One of the ways is to turn the carbon dioxide into rock. This is done by injecting the CO2 into a rock called peridotite which has minerals that react with the CO2 turning it into a solid magnesium carbonate. Such rocks are found in vast amounts in Oman that could store 10 percent of all the carbon emitted by humans in a year. A pipe line or trucks will carry either gas or liquid CO2 into the site. Normally, this reaction would be too slow, but this process could be made use of because of the high pressure involved. Columbia University’s geochemist Peter Kelemen says "Right now we’re working on finding that sweet spot where the system is self-sustaining." Another way of eliminating the green house gas is to inject the carbon dioxide into volcanic basalt 1800 feet under ground. Pressure keeps the gas dissolved and from leaking into the atmosphere. Eventually, the Carbon dioxide bonds with the rock to form a solid carbonate.

I believe that these ideas are indeed crucial to our survival. A combination of these techniques and us humans using less energy will help stabilize the earth. I think that we must give up some luxuries; we cannot depend on these methods alone. We have to cut back, and watch our carbon spending, along with the help of the scientists.

Temperature


Temperture is the measure of the movement of molecules or atoms in a substance. If the tempurature (movement) is higher, the particles colide with each other more often, giving of more energy. There are four ways to measure temperature, Fahrenheit, Celsius, Kelvin, and Rankine. Rankine is not common, but it is basically a scale that starts at absolute zero, and one Rankine degree is one Fahrenheit degree. Here are some places and temperatures on each temperature scale: (http://funphysics.jpl.nasa.gov/adventures/temperature-game.html)

Fahrenheit, Celsius, Kelvin

Boiling point: 212, 100, 373
Death Valley: 134, 57, 324
Human Body: 98.6, 37, 310
Room Temp.: 68, 20, 293
Freezing Point: 32, 0, 273
Mars: -81, -63, 210
Antartica: -128, -89, 183
Saturn: -229, -145, 128
Space: -454.54, -270, 2.7
Super Fluid Helium: -455.76, -271, 2.17

Extinct For Science?


After dissecting various organisms, I was given practical tests, tests that involve real specimens. On the last practical, the practical of the frog, the final question appeared, this question had been pondered by me since the beginning of the dissection period. The question was questioning the ethics of the practice of dissection. The answer I gave was to terminate this practice. This is partly because of the numbers:

For us, one class equals six specimens at six lab tables.
6x5 classes=30 specimens per unit

30x6 7/8 grade units=180 specimens for our school

180x2 middle schools=360 specimens for our town

This doesn't include the high school, or the extra specimens needed for the practical tests.

I have no knowledge on whether these animals were farmed our not, but if they were farmed, I believe it can be less shamed upon. If these animals were taken from the ecosystem, then the practice should stop immediately. Seeing the numbers above, organisms will become extinct very soon. Also, I believe that frogs are now endangered, and the most common organism to dissect is the frog. After the organism is removed from the ecosystem, predators will have to narrow down their food selections, or adapt to different foods, both of which are difficult to do in the short amount of time before starvation. Even if the animals are farmed, they shouldn't be slaughtered for a mature form of "child's play". It would be understandable that they would be killed for food, since we need food, and we consume plants along with animals, balancing out the slaughtering. Dissection after farming still goes against some people's ethics.


Some alternatives to dissection are virtual dissection, photographic documentation, and organism analogs.


Since technology is improving over the past years, I suspect it can be possible to create a virtual frog for dissection. Perhaps the image of the frog can be projected onto an interactive "lab tray" and much like a Smart Board, students can pick up specific dissecting tools and perform on the virtual organism. The con to this is that only the sense of sight is satisfied while virtually dissecting.


There are already plenty of photographs of dissections; students could observe these instead of the real specimen. A con to this is that the pictures are in two dimensions, not three.


Analogues of the organisms can be made, specific organs made of synthetic material to look and feel like the real organ. A student can dissect the analogue just like the regular one, but not get dissecting juices all over them or removing the organisms from the environment. A con would be that mass producing analogues will be costly.


In the end, I believe that dissection should be banned whether the organisms are farmed, or captured in the wild. There are plenty of texts books and photographs. Technology will help improve our experience. If we continue this practice, not much animals will be left on the planet. Likewise, there will be less to study.
