Coffee and math = good combination?
It was one Thursday afternoon where I spent hours rewriting the series of equations that were in notepad. I was in Starbucks while doing it. It took me a lot of patience and effort in checking the grouping of the equations. It caused me a bit of eye strain because I was just staring at the paper most of the time checking if I’m doing the right thing. The picture above is the product of my break-time from the stressful paper work.
