Evening Under the Stars: Blue Skies and Rainbows

Blue Skies and Rainbows aren’t just the domain of ELO and anthropomorphized green frogs – they’re a part of the type of normal weather everyone experiences. Dr. Joe Weingartner will explain exactly the sky is blue and why rainbows form during and after storms! Not only is the physics behind it not that complicated, but it’s fascinating!

Evening Under the Stars: Feathered Dinosaurs

Tuesday, 7 May 2013: 1st talk at 7PM, same talk at 7:45PM, observing starts at 7:30PM until 9PM. Meet in the lobby of Research Hall.

Just keep an eye out for weather – the event may be postponed or cancelled due to bad conditions – updates will be available here.

Sigma Xi Meeting – Monday November 12, 2012 at 6-8pm

Dear colleagues and students,

You are invited to attend the fall meeting of The George Mason University chapter of Sigma Xi.

Monday November 12, 2012
George’s in the Johnson Center

Meeting hIghlights

Guest speaker, Dr. Bob Weigel
Membership information
Undergraduate Research opportunities at Mason

Faculty, graduate, and undergraduate students from all fields of science and engineering are welcome to attend. You do not need to be a member. 

Sigma Xi is an international science and engineering honor society. For more information about the organization see: http://www.sigmaxi.org/. The goals of the GMU chapter will be to: promote interdisciplinary research among the various science and engineering departments on campus, and provide a means to honor outstanding senior and graduate students for their research.  

A limited number of chapter funded student memberships are available; interested students should plan to attend the meeting to learn more.

Please add this date to your calendar now and plan to join us for a terrific evening!

Best regards,
Rebecca Jones

CFD Seminar : Numerical simulation of flows with interfaces of fluids and frictional materials by Pablo Ortiz

Numerical simulation of flows with interfaces of fluids and frictional materials

Pablo Ortiz, University of Granada
Campus Fuentenueva, 18071 Granada (Spain)
Johnson Center 336,  Meeting Room F, 3:00PM

Refreshments will be served

Some approaches for the numerical simulation of environmental flows with interfaces will be outlined. Two main issues are considered. First, a method for the computation of fluid flow and sediment transport past evolutionary landforms will be treated. The model fully couples flow aloft with developing landforms. Numerical experiments verifying the adopted theoretical and numerical framework will be reproduced, and in particular, evolutionary sand dunes, a fundamental dynamical mechanism with challenging details. Second, a sign-preserving finite element method will be discussed. Sign-preservation is essential for algorithms to avoid unphysical computed
values of a positive definite property transported by a fluid flow.  Some numerical experiments and current developments  for shallow water flows will be reported.

Open Data = Open Access Wednesday Oct. 10, 2012

Open Data = Open Access: A Panel Discussion
Open Data Panel Flyer 

As Mason continues to celebrate Open Access Week throughout the month of October, we reflect on the spirit of innovation that has long been at the heart of the University’s philosophy.

This year’s panel, Open Data = Open Access, highlights the benefits and implications of using open data in scientific disciplines.  Join this event, hosted by the University Libraries and the School of Physics, Astronomy and Computational Sciences, held Wednesday, October 10, 3:00 pm – 4:30 pm in Research Hall, Room 163. A Q&A will follow the discussion.  Light refreshments will be served.

Featured speakers are Dr. Amy Friedlander, senior advisor to the Assistant Director of the Directorate for Social, Behavioral and Economic Sciences at the National Science Foundation; Dr. Kirk Borne, Mason professor of astrophysics and computational science; and Dr. Liping Di, Mason professor and director of the Center for Spatial Information Science and Systems
