What about brake fluid which is said to be incompressible. When I push down the brake pedal, the master cylindre pushes the brake liquid inside the hoses which tightens the brakes immediately? So what is the speed of propagation in this scenario if it cannot be faster than c even though brake fluid seems incompressible?
Celia Elliott is an academic professional with extensive experience in grant and proposal writing and journal publishing. She works closely with the department head and associate heads to develop external and internal resources to allow the department to meet its missions of education, research, and public service, and she works with faculty to increase external funding of their research programs.
In addition to her administrative responsibilities, Celia has been involved with the development of the senior thesis sequence for undergraduate physics majors since its inception in 2000. She is currently team-teaching (with Professor Douglas Beck ) two courses on technical communications and research skills, Physics 496 and Physics 499. In Spring 2013, she assisted Professor Lance Cooper with a new writing course for graduate students, PHYS 598PEN. Celia has also contributed to the development of programmatic activities for the department's NSF-sponsored "Research Experiences for Undergraduates" program since 1996.
