Hi I'm Jimmy, Welcome to my super cool page... I am currently an undergrad in Physics at UC Berkeley. In January 2009 I began working at the Space Sciences Lab with Sam Krucker on RHESSI Hard X-Ray data. You can see my SSL website for more details: sprg.ssl.berkeley.edu/~jgrayson Past work... During Summer 2008, I worked for Scott McIntosh at the High Altitude Observatory in Boulder, CO, as part of the REU program. Along with David Graham (U. Glasgow), I used genetic algorithms in IDL to analyze double-gaussian profiles in Solar transition region spectra. - Abstract - Presentation - Poster - Some Math 54 notes (Spring 2008, Lay and Nagle texts): Linear Algebra up to midterm 1: Theorems, Definitions Linear Algebra for midterm 2: Theorems, Definitions Differential Equations: Theorems, Definitions, Heat and Wave Equations IDL DeCal HW (Spring 2008): Assignment 1: swap_em, eightball.pro Assignment 2: fib.pro, my_fillarr.pro, my_fillarrloop.pro (loop version) Assignment 3: gaus.pro, gaussian.eps, mc_pi.pro, benchmark_output.txt Assignment 4: findel.pro, integrate.pro Assignment 5: fits2sav.pro, betelgeuse.sav, ascii2fits.pro, gal_cat_2_3.fits Assignment 6: forktrans.pro, forkgraph.eps Assignment 7: hrdiagram.eps, hrdiagramcolor.eps
