I’m writing about the article “Drones Put Spying Eyes in the Sky” by Stephen Omes published in “Science News for Students.” In this article, the author wants to teach the reader about the possibilities of the new technology known as drones. “Drones have enormous potential to change the way many different people work, since aerial robots can collect huge amounts of data in a short time.” As smaller and cheaper drones are developed and become available, people are using them for many different purposes. The author basically explores the facts, without giving any opinion about them. He shares three main different innovations in the use of drones that make a difference in the world.

In the first example, we are introduced to Thomas Snitch, a computer scientist at the University of Maryland, College Park, who is launching drones in South Africa to help stop poachers from killings rhinos. Snitch, “ combines a drone’s view with math and computer software to find and catch poachers before they strike. Jeff Sloan of the U.S. Geological Survey agency (USGS) recycles military drones for multiple purposes. He explains, “they fly cameras that capture images in natural color. Most also host video cameras that hunt for heat. Anything that emits heat- from vehicle engines to human bodies- produces infrared light. Thermal cameras can detect that infrared light, which the human eye cannot. The cameras push beyond what the human eye can see.” One of their projects is tracking wildlife. In 2009, Sloan’s agency used drones to monitor migration patterns and count the Sandhill Cranes in the San Louis Valley of Colorado. Rory Paul, is an engineer who works with Volt Aerial Robotics, a company that builds drones in Chesterfield, Missouri. Paul says, “ Almost any kind of sensor can be attached to a drone to make measurements. In 2012, Paul’s company used drones to observe a soybean field in Iowa. The cameras could detect insect damage without the farmer having to trek across hundreds of acres of field every day to protect his crops.

Many other uses of drones are described in this interesting article. Drones offer the possibility of increasing a farmer’s crop yield. Scientists are beginning to look at drones as a way of mapping landscapes. Scientists sent in drones to measure radiation levels at the power plant in Japan after the 2011 Tsunami. Recently, archeologists used drones to search for buried remains in a 1,000 year old settlement in the desert of New Mexico. Last spring, storm-chasers seeking to learn more about tornados, sent a drone into a supercell, a type of stormcloud that causes tornados. Drones are available on Amazon.com right now. They are exploring the possibility of using drones to deliver orders. And people have used drones to take aerial photographs of their properties.

The world is changing quickly, even in my short lifetime. I am impressed by the many ways that drones can be used to serve people: conserving and studying wildlife and increasing crop yields are just a few of the many possibilities this technology opens up for us. What if we could design micro drones that could explore microscopic things, including the human body? The possibilities are endless.

Field Trip Blog

Today, I went on a field trip to the Museum of the City of New York. I had a really great time, even though I arrived late from a Murrow tour. I thought the museum was very enjoyable and interesting. I especially loved the exhibit known as the Jeff Chien-Hsing Liao photographs. I appreciate the way he combined many smaller photos into one very large photograph- close to six feet in length. It’s fascinating the way that the pictures have an element of night, day, and morning in them. These were amazing pictures of New York, capturing the beauty of the city.

     I found the Activist New York Exhibit inspiring. So many New Yorkers have fought for their rights and their beliefs. The issues that environmental activists have taken on particularly struck me. Starting with the growing realization that the automobile was destructive to the environment, advocates began protesting against cars and urging their fellow citizens to use bicycles as much as possible. Bike activists have arranged many “Bike-Ins” in the last four decades to convince the city of New York to create separate bike lanes on city streets, and to generally raise awareness about bikes as great exercise, a valid mode of transportation, and a green house emissions-free machine. As I looked at the photographs of the bikers, I felt happy that people have been making an effort to pollute less, be more green, and convince the rest of us to do the same. After leaving the museum, I felt glad and proud to be a New Yorker now.

The Giver Reading Response

The Giver

What if you lived in a society where there is no choice for you and all the color, love, and all the feelings you have, have been eliminated? “The Giver,” by Lois Lowry is about an eleven-year-old boy named Jonas, who lives in a society many years ahead of ours. Is it true that as the Giver says, “when people have the freedom to choose, they choose wrong”?  In “The Giver,” the reader learns that as flawed as we are as human beings, and as safe as a controlled world can seem, we still yearn for the right to exercise our free will and to see the world through our own eyes and our own senses.

At the beginning of the story, Jonas is living his life like any normal kid, but sometimes he sees things, things we know to be colors. In Jonas’s world, the “elders” have eliminated all sight of color because, as the Giver says, “our people made that choice, the choice to go to Sameness. Before my time, before the previous time, back and back and back. We relinquished color when we relinquished sunshine and did away with differences…we gain control of many things. But we had to let go of others.” Jonas lives in a society where everyone must obey the rules and tell the truth. In order to prevent conflict, differences aren’t allowed. In this way, the society Jonas lives in has eliminated fear, pain, envy, and hate. Jonas is unwilling to let go of some important choices.

Jonas is different from all the others in his community because he has the gift of seeing colors. I think this is a metaphor for Jonas’s capacity to see the nuance in life as apposed to just black and white: “if everything’s the same, then there aren’t any choices! I want to wake up in the morning and decide things!” In the final scenes of the book, Jonas risks his life to have a choice and to give the possibility of choice to his community. Starving, he thinks to himself “If he had stayed, he would have starved in other ways. He would have lived a life hungry for feelings, for color, for love.” The reader never learns whether Jonas brings color back to his world or not, but will know that he is willing to die trying. After reading this book, I appreciate all the choices, colors, nuance, and feelings that we have in our society.
