I am an identical twin. Whether I am in school or at the supermarket, I always notice the creepy stares as well as the following: “Who’s older? Which one are you? Do you like being a twin? Am I seeing double?” How does one go about answering questions such as these? I’ve always had an identical twin, an exact copy of my genetic make-up, and people have never ceased to be amazed by this. I have trained myself to answer these questions and yes, I love being a twin. I always have a friend by my…
While rich in talent and creativity, what the group lacked was money (sometimes to the point of near starvation) and connections, a reality that Zappa’s independent nature lost an early battle. But sometimes you have to sleep with The Man. An initial record deal came from what certain perspectives might characterize as a happy accident, fame came…
Any object that has a magnetic field is a magnet. In ancient times, the Greeks are attributed to using lodestone, a black l rock because it helped them to find their destination. The first documented man-made magnetic device was the sailor's compass. The development of the first navigational…
When a magnet is in motion near a non-magnetic conductor such as copper and aluminium eddy currents are induced in the conductor, causing a dissipative force called magnetic braking force, or a change in magnetic flux (figure 2). This force is dependent on: The size and shape of the conductor and magnet The strength of the magnet (μ) The conductors conductivity (σ_c) The distance between the conductive surface and the magnet (d) The velocity of the magnet (v) According to Faraday’s law,…
Science is one of the few disciplines that continues to develop in our society, whether it is through technology or new discoveries. When considering my own relationship to the world of science, I often consider the past science classes I’ve taken. Thinking back to learning about the scientific method in elementary school to constructing science fair projects for six consecutive years had me realize how far I had come without really questioning science. The year I had made it past the first…
While this is in fact a more recent study the same holds true for older boomtowns. Sour Lake experienced a huge influx of unmarried men to a town with little else to offer other than the work in the oil industry. The town had no bars, no theater, no stores, essentially no businesses other than the hotel. Many of these single men arrived with no shelter or food and no way to attain these things. Consequently, these men had a lot of time on there hands in which to get into trouble. As a…
The memory of the Khmer Rouge and the prison facility S-21 is one that is shadowed by repressed memories, lack of knowledge of the events, and apathy of the horrors that took place. By analyzing the similarities, differences, and the purpose of the book and movie we can see the issues that we have today in memorializing the genocide in Cambodia. The book Voices from S-21, and the movie Khmer Rouge: Killing machine, try and address the misconceptions that the perpetrators have in their…
magnets are the most common ones. Once they are magnetized they stay so (although they can lose much of their magnetic force). They can be metals found in nature. Temporary magnets hold the properties of a magnet while in a magnetic field, but lost these properties once the field goes away. An example of this would be a paper clip that is charged and can act as a magnet for a limited time. Electromagnets are wires wrapped around a metal center (usually iron). The wires have a current flowing…
They’ll use a nail and a battery to create a magnetic field. It’ll turn the nail into a magnet. Students should be sure to write down their observations throughout the experiment. Students will wrap the center portion of the wire around the nail 10 times so that it forms a coil. They should have extra wire…
The mini torsion device that will be designed for this senior design project will apply a torsional load to a small cylindrical sample with a diameter of 5 mm or 6 mm. The device will need to fit under an optical microscope and will not be able to exceed the weight limits of the sample stage on the optical microscope so that Raman microscopy can be performed on the sample while it is under a torsional load. The device will also need to collect data and calculate the angle of twist of the sample.…
