\textbf{Please compare your description of Johnson Noise and Shot Noise below in your Aims and Introduction Sections with the short description I provided you in the getting started instructions for this lab (reprinted below): }  \textit{\begin{quote}}  \textit{By measuring Johnson noise --- the fluctuating voltage that arises due to the random walk motion of electrons in a resistor (even when current isn't flowing through it) ---- as a function of temperature and frequency ``bandwidth'', we can determine Boltzmann's constant $k_B$, the fundamental constant connecting temperature $T$ to energy $k_B T$. }  \textit{\end{quote}}  \textit{\begin{quote}}  \textit{By measuring Shot noise --- the fluctuations in a measured current of electrons due to quantization of charge --- we can determine the fundamental unit of charge $e$ (the charge on an electron). }  \textit{\end{quote}}  \textit{\begin{quote}}  \textit{Who would have thought you could discover fundamental physics from simple ``noise?'' That's pretty neat! }  \textit{\end{quote}}  \textbf{Notice how this version tries to provide a description of }  \begin{enumerate}  \item what Johnson noise and Shot noise are  \item what we need to measure (and as a function of what variables)  \item and what we aim to determine from the measurement (for example, values for fundamental constants of physics $k_B$ and $e$)  \end{enumerate}.  \textbf{Do you think your classmates in PHY350 would understand these three points from \textit{your paper}, as written?} If not, you need to rewrite your paper in a way that they can.   \textbf{Do you understand these 3 points yourself?} If not, your responsibility is to review the physics --- I recommend reviewing the introductions to sections 1 and 3 of your teachspin manual! --- and make sure you do! Then, rewrite the paper to make it clear you understand what you were doing (and why).
