The 4 . 2 second part was sped up and slowed down as well . Watch the popped balloons dropping when you use YouTubes video speed setting .

That was forever ago . <| sep |> I have just finished taking MATH 235 . Before taking 135 last year , I hadn ' t touched proper math in about 8 years . So I found 135 and 136 also difficult to wrap my head around at first . This was true of 235 too , though I don ' t think it was really any more difficult than the other units , given that it was building on the foundation of those units too . It certainly takes a bit of work , and maybe a bit more mental wrangling to get good intuition on some of the ideas extradimensional stuff than earlier units , but I don ' t think the actual math was much more difficult .
