the Junospacecraft mission at Jupiter. To study Earth’s ionosphere, MTSU will collect
radio astronomy data during upcoming solar eclipses.We are part of a NASA-affiliated
education project called Radio JOVE that focuses on science education and outreach.

this project will lead to a levitation system that can hold water droplets up to several

and soldering skills will be learned), characterize the different designs (e.g. how
much mass can be held in place?)

Measuring the mass of a soap bubble, Dr. Nathanael Smith
Overview: Have you ever wondered how much a soap bubble weighs? Have you ever thought how you
could possibly measure the mass of a soap bubble? If so, this project is for you!
(If you haven’t wondered about it until now, but think the project sounds cool, this
project is for you, too!)
Activities: Together we will try to figure out a way to measure the mass of a soap bubble. It’s
not as easy as it sounds! You will need to become good at blowing bubbles, potentially
use motion analysis software (and a super duper high-speed camera), and anything else
we can think of.
Minimum student background: An interest in physics.
Bouncing soap bubbles, Dr. Nathanael Smith
Overview: Not long ago I was trying to freeze a soap bubble (this is something you really can
do) by placing it in a cool box with dry ice. To my surprise, the bubble wouldn’t
get down near the dry ice. It kept bouncing off the cool, dense layer of air that
formed over the dry ice. This project will explore the dynamics of the bouncing soap
bubble as it moves and bounces through air with a strong temperature gradient.
Activities: This project will involve both computational and practical components. The dynamics
of a bouncing bubble will be modeled using basic mechanics using either Matlab or
Python. From the model, we should be able to predict the amplitude and frequency of
the bouncing bubble. We will also experimentally measure the motion of a bouncing
bubble, and use video motion analysis to compare experimental results with those of

few tens of microns) on solid substrates. We will use an optical interference technique
to monitor the thickness of a liquid film while it thins. Experimental results will
be compared to theoretical predictions.
Activities: Set up and optimize the optical interference experiment. Measure the film thickness
concurrently in two different locations during the spin coating process. Model the
film thickness using Matlab or Python.

Numerical studies of disordered and strongly correlated electron systems, Dr. Hanna
Overview: In many novel materials the motion of electrons is very correlated due to strong electron-electron
interactions or disorder. As a result in such systems the various exotic phases of
matter and complex phenomena emerge. This includes electron localization, metal-insulator
transitions, superconductivity, and quantum magnetism. Despite pure scientific interest,
such strongly correlated electron materials are also technologically promising with
potential application in energy transmission, energy storage and electronic technology.
Theoretical description of such systems presents one of the main challenges of the
modern Condensed Matter Physics. With increasing computing power, numerical analysis has
now become a central tool in the analysis of the different phases arising in materials
in condensed matter physics. Our primary focus is the use of various numerical methods
to calculate the properties of electrons (correlation effects, spectral functions)
and phase transitions in such materials.

Newton’s equations of motion. Using computer simulations, it is possible to build
numerical models of these collisions that can be compared to observations of interacting
