When we say that two particles are quantumly entangled, we mean that the particles cannot be looked at independently even when separated by great distances. This means that if we measure one particle, we will automatically get the measurements of the other. This concept is spooky, and can be useful in studying the nature of…

    Absorption spectroscopy is popular form of chemical identification and characterization. Typically, light is passed through a sample once and the intensity of the light after passing through the sample is measured. If light is absorbed by a sample, we expect the amount absorb to increase if the concentration of the solution or the…

My name is Collin Hendershot. For my Junior Independent Study project I observed the effect of concavity on the aerodynamics of high speed automobiles. The two important aerodynamic characteristics of automobiles are downforce and drag. Downforce is the force of air pushing a car toward the road and drag is the force on the car…

I have always thought that one of the most outdated technologies we currently employ in the large scale is propellers for ships. While this isn’t a critical fault in our world it does lead to a lot of inefficiencies. Modern trade ships and super-tankers use millions of tons of fuel annually. This does a great deal…

Solar sails utilize the change in momentum of photons as a means of propulsion. This allows spacecraft with solar sails to significantly reduce their mass, since they do not have to carry onboard fuel (in comparison to traditional rocket-based spacecraft). This project aims at designing a program to display the dynamics of a solar-sail-based spacecraft…

This project uses an electronic circuit to demonstrate something called stochastic resonance. Stochastic resonance (SR) is present many places in nature–from dictating the timing of ice ages to aiding in fish hearing. So, what is it? SR is simply when a random noise signal serves to boost the strength of another, cleaner signal. Audio is…

The purpose of my experiment was to analyze whether the behavior of an RLC (Resistor, Inductor, Capacitor) circuit is noticeably affected by replacing the inductor with an oscillating spring. Common inductors take the form of solenoids which are helical coils of wire that are wrapped around a core. This core can be made of different…

For my Junior Independent Study, I looked into some cool physics videos to find an interesting topic to explore. I found a youtube video about the University of New Mexico Couette cell apparatus for demonstrating laminar flow and decided that watching fluid blend together and then separate out again was an interesting concept. The project…
