Springs Released from Uniform Circular Motion

Matt Carnaghi’s freshman research project on the motion of a collapsing spring released from uniform circular motion has been submitted to the American Journal of Physics. The project resulted in a fruitful collaboration with Jeff Regester of Greensboro Day School and Tom Dooling of UNC Pembroke. A YouTube video describing the project and its results […]

Update on Alan Vasquez Soto’s Research

Alan Vasquez Soto (a) has spent his SuRPS time focusing on CS 1246, a pulsating star about 600 light-years from Earth. Similar to a vibrating guitar string, this star ‘pulses’ once every six minutes, which results in a periodic change in its luminosity. Alan has been using the SKYNET web interface (b) to monitor CS […]

This week in Dr. Barlow’s Universe

Rodrigo Catalan-Hurtado is using the 1.5-meter SMARTS telescope in Chile to collect nightly optical spectra of a newly-discovered binary star system. The attached figure shows an example of a single spectral image. The bright vertical “stripes” are individual spectral orders that together cover the wavelength range 450 nm (leftmost order) to 850 nm (rightmost order). […]

This week in Dr. Fiser’s lab

This week we used a potentiostat to create arrays of nickel tubes ten microns long and approximately 600 nm in diameter. The potentiostat sends a current through a solution of nickel ions, causing the ions to travel into a template with cylindrical pores, creating the tubes. We analyzed these tubes using the scanning electron microscope […]

2015 SuRPS – Matthew Carnaghi

Matthew Carnaghi (’16) is a senior majoring in physics and computer science. Matt is working with Dr. Fiser at HPU in the university’s inaugural Summer Research Program in the Sciences (SuRPS). Their project is titled “Using biomimetic cilia arrays to investigate the flow of mucus in the human lung.” Their goal is to use life-sized artificial cilia (high […]

Physics in Non-Inertial Reference Frames Poster at the Spring 2014 NCS-AAPT Meeting in Boone, North Carolina This project focused on creating classroom-friendly videos of motion in non-inertial reference frames where fictitious forces are required in order to apply Newton’s laws. To explore motion in a linearly accelerating frame, we attached a camera to a fancart […]

Jacob Brooks, 2014 AAPT Winter Meeting

Measuring and Modeling a Boleadora Poster at the 2014 AAPT Winter Meeting in Orlando, Florida The effects of the throwing technique on the motion of a boleadora in flight were investigated. The boleadora is an ancient hunting weapon made of three individual masses connected by rope to a common knot. The dynamics of the boleadora […]

Springs Released From Uniform Circular Motion – The Slinky Drop Extended Poster at the 2014 AAPT Winter Meeting in Orlando, Florida The path of a spring released from uniform circular motion was investigated and compared to a computational model. This study is an extension of the “Slinky drop” experiment, which consists of holding the top […]

Measuring Viscous Fluid Flow with Biomimetic Cilia Presented at the 2013 BigSURS Meeting, High Point University To understand fluid flow driven by cilia in biological systems such as in the lungs and in vertebrate embryos, we fabricated arrays of biomimetic cilia, core-shell microstructures that mimic the size of biological cilia. These biomimetic cilia are 10 […]

An Apparatus to Measure Young’s Modulus Presented at the 2013 BigSURS Meeting, High Point University Young’s modulus, a measure of the deformation of a material in response to an applied force, is an integral variable to consider when designing and engineering systems such as buildings or bridges. Young’s Modulus is the slope of a stress […]
