Zwa?

I was looking through my class notepad for something, when I noticed this drawing I did from my last Husserl class (you can click to expand if you want to see how awesomtastic my handwriting is):


It showcases a philosopher sweeping up after a scientist, who appears to be tossing bits and pieces of history in his wake.

My question is - what does this mean, and why did I create it?! I have no recollection of this. Everything seems way more profound when you don't remember its origins (which is one of the suspicions I have of the tendancy of Heideggerians to obsess over correlations with ancient Greek thought...)
