   * started figuring out how the proton-neutron mass splitting and the deuteron properties depend on our input parameters
   * fixed several bugs in the code, continued familiarizing ourselves with Fortran and the BBN code
+=== Wednesday, June 11 ===
+  * produced plots of BBN abundance as function of grav. constant
+  * tried to calculate and fit the $p(n,\gamma)d$ rate to use as input; partially succeeded
+=== Thursday, June 12 ===
+  * produced data and plots for BBN abundance as function of $\Lambda_{QCD}$ and $\mu_n$
+  * also looked at the individual effects of $\Lambda_{QCD}$ on the actual inputs to the BBN calculation (neutron-proton mass splitting, neutron life time, deuteron energy, $p(n,\gamma)d$ rate) and identified the life time effect as the main effect driving the change in the <sup>4</sup>He abundance.
