For anyone in the US, you could celebrate the Golden Ratio Day today 🤓 Enjoy the day! Mathematicians since Euclid have studied the properties of the golden ratio, including its appearance in the dimensions of a regular pentagon and in a golden rectangle, which may be cut into a square and a smaller rectangle with the same aspect ratio. The golden ratio has also been used to analyze the proportions of natural objects as well as man-made systems such as financial markets, in some cases based on dubious fits to data. #mathgeek #celebrating #phiday #goldenratio #math #geometry
