 Many of the figures in this summary were taken directly from the Script or Lecture notes created by Professor Vasile Gradinaru.
 
+To add to the one quote regarding Python and type annotation: This is objectively wrong and a really hot take.
+Yes, this applies for small projects, but libraries \textit{DO} need type annotation, as you can't possibly read the entire library's code to use it.
+The reason this quote was even included here is that his coding style is really awful (yes, there were semicolons in his Python-code sometimes)
+and he rambled about bad coding style for about 10 minutes in this lecture.
+
+Meanwhile his code has variable names that neither future him, nor anybody else can make much sense of intuitively.
+You can get away without type annotation in Python, even in larger projects, but only if you give variables proper names!
+
+Moral of the story: Use descriptive variable names and do NOT use $t$, $tt$, $ttt$, \dots
