Feynman Diagrams: A Toy Example
We examine the moments of the Gaussian integral and relatethem to Feynman diagrams. We next introduce a quarticterm and show how it leads to a seemingly paradoxical result.The article is addressed to the novice, but we believe that itmay also serve as an opening lecture on the topic of Feynmandiagrams.

Recent Progress on the Black Hole Information Paradox: Computation of the Page Curve
We give a brief overview of the black hole information problem and describe qualitatively the recent research that shows that the von Neumann entropy of Hawking radiation follows the Page curve, and hence is consistent with unitary, information-preserving time evolution.
