Another day aboard with nowhere to go, hence this slightly tenuous floor tiling pattern - I thought it was quite pretty though!
Today we visited an active volcano near Santorini, which was all very interesting, but had limited opportunities for taking mathematical photos. The best I could find today were some Greek letters on a can of beer and some pretty reflections in the water when we arrived on Mykonos in the evening.
Monday was a day at sea, with not much to do except lounge around in the sun. We retreated to one of the bars in the afternoon when it got too hot, and decided to attempt to play Set with playing cards.
As we spent the day driving to Manchester, then flying to Munich and finally on to Venice, then getting a coach to the port, then doing our lifeboat safety drill, I had very little time to spot any maths. However, I decided that the infinite mirrored lifts onboard our boat were definitely mathematical enough to become my first photo in the challenge!
