Another emblematic building of Pisa is the Duomo (the cathedral). Galileo Galilei was inside the cathedral when he observed the movement of the lamp hanging from the ceiling. He noticed that its oscillatory movement was constant so he discovered the isochronic property of the pendulum. The current lamp isn’t tha same lamp which Galileo observed that lucky day for the science (of course not!) but you can always look at it and try to imagine Galileo Galilei’s thoughts in that moment.
Look at it and enjoy this magic moment:
