▲ Siena is a city in the Tuscany region of Italy and the capital of the province of Siena. Its historic center was designated as a UNESCO World Heritage Site in 1995. Siena is renowned for its distinctive cuisine, art, museums, medieval views, and the Palio horse race. The streets follow the natural contours of the hills, lined with ancient buildings featuring red brick roofs. Strolling through them feels like stepping back in time to the distant Middle Ages.

▲ In 1990, the historic center of San Gimignano was designated as a World Heritage Site. Today, this ancient town has become a popular tourist destination, often included as a half-day stop when visiting Florence or Siena. Notably, the town is famous for its Vernaccia white wine and saffron. It also boasts a renowned gelato shop, Gelateria Dondoli, which has won multiple World Gelato Championship titles. Be sure to try their signature "Italian Garden" flavor, infused with various spices for a uniquely delightful taste!

▲ "Do two spheres of different sizes hit the ground simultaneously?" Students who have studied physics will surely remember that the great physicist Galileo conducted his famous free-fall experiment right here—at the Leaning Tower of Pisa. The result showed both spheres landed at the same time, proving that an object's falling speed is independent of its mass. This experiment overturned the ancient Greek belief that an object's size determined its falling speed and laid the foundation for modern mechanics. The free-fall experiment is considered one of the most renowned scientific experiments, and the Leaning Tower of Pisa has thus gained worldwide fame.
